我编写了一个简单的类（AlertDialogBuilder），您可以使用它在按下对话框按钮时禁用自动关闭功能。

它还与Android 1.6兼容，因此它不使用OnShowListener（仅API>=8可用）。

因此，您可以使用此CustomAlertDialogBuilder，而不是使用AlertDialogBuilder。最重要的部分是不应该调用create（），而应该只调用show（）方法。我添加了setCanceledOnTouchOutside（）和setOnDismissListener等方法，这样您仍然可以直接在生成器上设置它们。

我在Android 1.6、2.x、3.x和4.x上测试了它，所以它应该工作得很好。如果你发现一些问题，请在这里评论。

package com.droidahead.lib.utils;

import android.app.AlertDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.view.View;
import android.view.View.OnClickListener;

public class CustomAlertDialogBuilder extends AlertDialog.Builder {
    /**

    private CharSequence mPositiveButtonText = null;
    private CharSequence mNegativeButtonText = null;
    private CharSequence mNeutralButtonText = null;

    private DialogInterface.OnDismissListener mOnDismissListener = null;

    private Boolean mCancelOnTouchOutside = null;

    public CustomAlertDialogBuilder(Context context) {
        super(context);
    }

    public CustomAlertDialogBuilder setOnDismissListener (DialogInterface.OnDismissListener listener) {
        mOnDismissListener = listener;
        return this;
    }

    @Override
    public CustomAlertDialogBuilder setNegativeButton(CharSequence text, DialogInterface.OnClickListener listener) {

    @Override
    public CustomAlertDialogBuilder setPositiveButton(CharSequence text, DialogInterface.OnClickListener listener) {
        mPositiveButtonListener = listener;
        mPositiveButtonText = text;
        return this;
    }

    @Override
    public CustomAlertDialogBuilder setNegativeButton(int textId, DialogInterface.OnClickListener listener) {
        setNegativeButton(getContext().getString(textId), listener);

    }



    @Override
    public AlertDialog create() {
        throw new UnsupportedOperationException("CustomAlertDialogBuilder.create(): use show() instead..");
    }

    @Override
    public AlertDialog show() {
        final AlertDialog alertDialog = super.create();

        DialogInterface.OnClickListener emptyOnClickListener = new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) { }
        };


        // Enable buttons (needed for Android 1.6) - otherwise later getButton() returns null
        if (mPositiveButtonText != null) {
            alertDialog.setButton(AlertDialog.BUTTON_POSITIVE, mPositiveButtonText, emptyOnClickListener);
        }

        if (mNegativeButtonText != null) {
            alertDialog.setButton(AlertDialog.BUTTON_NEGATIVE, mNegativeButtonText, emptyOnClickListener);
        }

        if (mNeutralButtonText != null) {
            alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, mNeutralButtonText, emptyOnClickListener);
        }

        // Set OnDismissListener if available
        if (mOnDismissListener != null) {
            alertDialog.setOnDismissListener(mOnDismissListener);
        }

        if (mCancelOnTouchOutside != null) {
            alertDialog.setCanceledOnTouchOutside(mCancelOnTouchOutside);
        }

        alertDialog.show();

        // Set the OnClickListener directly on the Button object, avoiding the auto-dismiss feature
        // IMPORTANT: this must be after alert.show(), otherwise the button doesn't exist..
        // If the listeners are null don't do anything so that they will still dismiss the dialog when clicked
        if (mPositiveButtonListener != null) {
            alertDialog.getButton(AlertDialog.BUTTON_POSITIVE).setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    mPositiveButtonListener.onClick(alertDialog, AlertDialog.BUTTON_POSITIVE);
                }
            });
        }

        if (mNegativeButtonListener != null) {
            alertDialog.getButton(AlertDialog.BUTTON_NEGATIVE).setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    mNegativeButtonListener.onClick(alertDialog, AlertDialog.BUTTON_NEGATIVE);
                }
            });
        }

        if (mNeutralButtonListener != null) {
            alertDialog.getButton(AlertDialog.BUTTON_NEUTRAL).setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    mNeutralButtonListener.onClick(alertDialog, AlertDialog.BUTTON_NEUTRAL);
                }
            });
        }

        return alertDialog;
    }   
}

EDIT下面是一个关于如何使用CustomAlertDialogBuilder的小示例：

// Create the CustomAlertDialogBuilder
CustomAlertDialogBuilder dialogBuilder = new CustomAlertDialogBuilder(context);

// Set the usual data, as you would do with AlertDialog.Builder
dialogBuilder.setIcon(R.drawable.icon);
dialogBuilder.setTitle("Dialog title");
dialogBuilder.setMessage("Some text..");

// Set your buttons OnClickListeners
dialogBuilder.setPositiveButton ("Button 1", new DialogInterface.OnClickListener() {
    public void onClick (DialogInterface dialog, int which) {
        // Do something...

        // Dialog will not dismiss when the button is clicked
        // call dialog.dismiss() to actually dismiss it.
    }
});

// By passing null as the OnClickListener the dialog will dismiss when the button is clicked.               
dialogBuilder.setNegativeButton ("Close", null);

// Set the OnDismissListener (if you need it)       
dialogBuilder.setOnDismissListener(new DialogInterface.OnDismissListener() {
    public void onDismiss(DialogInterface dialog) {
        // dialog was just dismissed..
    }
});

// (optional) set whether to dismiss dialog when touching outside
dialogBuilder.setCanceledOnTouchOutside(false);

// Show the dialog
dialogBuilder.show();

对于ProgressDialogs

要防止对话框自动关闭，必须在显示ProgressDialog后设置OnClickListener，如下所示：

connectingDialog = new ProgressDialog(this);

connectingDialog.setCancelable(false);
connectingDialog.setCanceledOnTouchOutside(false);

// Create the button but set the listener to a null object.
connectingDialog.setButton(DialogInterface.BUTTON_NEGATIVE, "Cancel", 
        (DialogInterface.OnClickListener) null )

// Show the dialog so we can then get the button from the view.
connectingDialog.show();

// Get the button from the view.
Button dialogButton = connectingDialog.getButton( DialogInterface.BUTTON_NEGATIVE);

// Set the onClickListener here, in the view.
dialogButton.setOnClickListener( new View.OnClickListener() {

    @Override
    public void onClick ( View v ) {

        // Dialog will not get dismissed until you call dismiss() explicitly.

    }

});

对于API 8之前的版本，如果editText的内容不正确，我使用一个布尔标志、一个关闭监听器并再次调用dialog.show来解决这个问题。这样地：

case ADD_CLIENT:
        LayoutInflater factoryClient = LayoutInflater.from(this);
        final View EntryViewClient = factoryClient.inflate(
                R.layout.alert_dialog_add_client, null);

        EditText ClientText = (EditText) EntryViewClient
                .findViewById(R.id.client_edit);

        AlertDialog.Builder builderClient = new AlertDialog.Builder(this);
        builderClient
                .setTitle(R.string.alert_dialog_client)
                .setCancelable(false)
                .setView(EntryViewClient)
                .setPositiveButton("Save",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,
                                    int whichButton) {
                                EditText newClient = (EditText) EntryViewClient
                                        .findViewById(R.id.client_edit);
                                String newClientString = newClient
                                        .getText().toString();
                                if (checkForEmptyFields(newClientString)) {
                                    //If field is empty show toast and set error flag to true;
                                    Toast.makeText(getApplicationContext(),
                                            "Fields cant be empty",
                                            Toast.LENGTH_SHORT).show();
                                    add_client_error = true;
                                } else {
                                    //Here save the info and set the error flag to false
                                    add_client_error = false;
                                }
                            }
                        })
                .setNegativeButton("Cancel",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,
                                    int id) {
                                add_client_error = false;
                                dialog.cancel();
                            }
                        });
        final AlertDialog alertClient = builderClient.create();
        alertClient.show();

        alertClient
                .setOnDismissListener(new DialogInterface.OnDismissListener() {

                    @Override
                    public void onDismiss(DialogInterface dialog) {
                        //If the error flag was set to true then show the dialog again
                        if (add_client_error == true) {
                            alertClient.show();
                        } else {
                            return;
                        }

                    }
                });
        return true;

编辑：这只适用于一些评论中提到的API 8+。

这是一个迟到的回答，但您可以在AlertDialog中添加一个onShowListener，然后可以覆盖按钮的onClickListener。

final AlertDialog dialog = new AlertDialog.Builder(context)
        .setView(v)
        .setTitle(R.string.my_title)
        .setPositiveButton(android.R.string.ok, null) //Set to null. We override the onclick
        .setNegativeButton(android.R.string.cancel, null)
        .create();

dialog.setOnShowListener(new DialogInterface.OnShowListener() {

    @Override
    public void onShow(DialogInterface dialogInterface) {

        Button button = ((AlertDialog) dialog).getButton(AlertDialog.BUTTON_POSITIVE);
        button.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View view) {
                // TODO Do something

                //Dismiss once everything is OK.
                dialog.dismiss();
            }
        });
    }
});
dialog.show();

可以添加builder.show（）；在返回之前的验证消息之后；

这样地

    public void login()
{
    final AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setView(R.layout.login_layout);
    builder.setTitle("Login");



    builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener()
    {
        @Override
        public void onClick(DialogInterface dialog, int id)
        {
            dialog.cancel();
        }
    });// put the negative button before the positive button, so it will appear

    builder.setPositiveButton("Ok", new DialogInterface.OnClickListener()
    {
        @Override
        public void onClick(DialogInterface dialog, int id)
        {
            Dialog d = (Dialog) dialog;
            final EditText etUserName = (EditText) d.findViewById(R.id.etLoginName);
            final EditText etPassword = (EditText) d.findViewById(R.id.etLoginPassword);
            String userName = etUserName.getText().toString().trim();
            String password = etPassword.getText().toString().trim();

            if (userName.isEmpty() || password.isEmpty())
            {

                Toast.makeText(getApplicationContext(),
                        "Please Fill all fields", Toast.LENGTH_SHORT).show();
                builder.show();// here after validation message before retrun
                               //  it will reopen the dialog
                              // till the user enter the right condition
                return;
            }

            user = Manager.get(getApplicationContext()).getUserByName(userName);

            if (user == null)
            {
                Toast.makeText(getApplicationContext(),
                        "Error ethier username or password are wrong", Toast.LENGTH_SHORT).show();
                builder.show();
                return;
            }
            if (password.equals(user.getPassword()))
            {
                etPassword.setText("");
                etUserName.setText("");
                setLogged(1);
                setLoggedId(user.getUserId());
                Toast.makeText(getApplicationContext(),
                        "Successfully logged in", Toast.LENGTH_SHORT).show();
               dialog.dismiss();// if every thing is ok then dismiss the dialog
            }
            else
            {
                Toast.makeText(getApplicationContext(),
                        "Error ethier username or password are wrong", Toast.LENGTH_SHORT).show();
                builder.show();
                return;
            }

        }
    });

    builder.show();

}

另一种解决方案

我想从用户体验的角度提出另一个答案。

为什么要在单击按钮时阻止对话框关闭？大概是因为您有一个自定义对话框，用户尚未在其中做出选择或尚未完全填写所有内容。如果他们还没有完成，那么你根本不应该让他们点击肯定按钮。只要禁用它，直到一切就绪。

这里的其他答案提供了许多技巧来覆盖积极的按钮点击。如果这一点很重要的话，安卓系统难道不会提供一个方便的方法吗？他们没有。

相反，Dialogs设计指南显示了这种情况的一个示例。在用户做出选择之前，“确定”按钮将被禁用。根本不需要任何压倒一切的技巧。用户很明显，在继续之前，仍需要做一些事情。

如何禁用正极按钮

有关创建自定义对话框布局的信息，请参阅Android文档。它建议您将AlertDialog放在DialogFragment中。然后，您需要做的就是在布局元素上设置侦听器，以知道何时启用或禁用肯定按钮。

如果自定义对话框具有单选按钮，请使用RadioGroup.OnCheckedChangeListener。如果自定义对话框有复选框，请使用CompoundButton.OnCheckedChangeListener。如果自定义对话框具有EditText，则使用TextWatcher。

正面按钮可以这样禁用：

AlertDialog dialog = (AlertDialog) getDialog();
dialog.getButton(AlertDialog.BUTTON_POSITIVE).setEnabled(false);

这是一个完整的正在工作的DialogFragment，带有一个禁用的肯定按钮，如上图所示。

import android.support.v4.app.DialogFragment;
import android.support.v7.app.AlertDialog;

public class MyDialogFragment extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        // inflate the custom dialog layout
        LayoutInflater inflater = getActivity().getLayoutInflater();
        View view = inflater.inflate(R.layout.my_dialog_layout, null);

        // add a listener to the radio buttons
        RadioGroup radioGroup = (RadioGroup) view.findViewById(R.id.radio_group);
        radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(RadioGroup radioGroup, int i) {
                // enable the positive button after a choice has been made
                AlertDialog dialog = (AlertDialog) getDialog();
                dialog.getButton(AlertDialog.BUTTON_POSITIVE).setEnabled(true);
            }
        });

        // build the alert dialog
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setView(view)
                .setPositiveButton("OK", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int id) {
                        // TODO: use an interface to pass the user choice back to the activity
                    }
                })
                .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        MyDialogFragment.this.getDialog().cancel();
                    }
                });
        return builder.create();
    }

    @Override
    public void onResume() {
        super.onResume();

        // disable positive button by default
        AlertDialog dialog = (AlertDialog) getDialog();
        dialog.getButton(AlertDialog.BUTTON_POSITIVE).setEnabled(false);
    }
}

自定义对话框可以从如下活动运行：

MyDialogFragment dialog = new MyDialogFragment();
dialog.show(getFragmentManager(), "MyTag");

笔记

为了简洁起见，我省略了将用户选择信息传递回活动的通信接口。不过，文档显示了如何做到这一点。该按钮在onCreateDialog中仍然为空，因此我在onResume中禁用了它。如果用户切换到另一个应用程序，然后在不关闭对话框的情况下返回，则会再次禁用它。这可以通过取消选择任何用户选项或从onCreateDialog调用Runnable来在下次运行循环中禁用按钮来解决。view.post（newRunnable（）{@覆盖公共空运行（）{AlertDialogdialog=（AlertDialog）getDialog（）；dialog.getButton（AlertDialog.BUTTON.POSITIVE）.setEnabled（false）；}});
