超简单的Kotlin方法

 with(AlertDialog.Builder(this)) {
        setTitle("Title")
        setView(R.layout.dialog_name)
        setPositiveButton("Ok", null)
        setNegativeButton("Cancel") { _, _ -> }
        create().apply {
            setOnShowListener {
                getButton(AlertDialog.BUTTON_POSITIVE).setOnClickListener {
                    //Validate and dismiss
                    dismiss()
                }
            }
        }
    }.show()

它可以用最简单的方法构建：

带有自定义视图和两个按钮（正和负）的警报对话框。

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()).setTitle(getString(R.string.select_period));
builder.setPositiveButton(getString(R.string.ok), null);

 builder.setNegativeButton(getString(R.string.cancel), new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {

    // Click of Cancel Button

   }
 });

  LayoutInflater li = LayoutInflater.from(getActivity());
  View promptsView = li.inflate(R.layout.dialog_date_picker, null, false);
  builder.setView(promptsView);

  DatePicker startDatePicker = (DatePicker)promptsView.findViewById(R.id.startDatePicker);
  DatePicker endDatePicker = (DatePicker)promptsView.findViewById(R.id.endDatePicker);

  final AlertDialog alertDialog = builder.create();
  alertDialog.show();

  Button theButton = alertDialog.getButton(DialogInterface.BUTTON_POSITIVE);
  theButton.setOnClickListener(new CustomListener(alertDialog, startDatePicker, endDatePicker));

警报日志正面按钮的CustomClickLister：

private class CustomListener implements View.OnClickListener {
        private final Dialog dialog;
        private DatePicker mStartDp, mEndDp;
    public CustomListener(Dialog dialog, DatePicker dS, DatePicker dE) {
        this.dialog = dialog;
        mStartDp = dS;
        mEndDp = dE;
    }

    @Override
    public void onClick(View v) {

        int day1  = mStartDp.getDayOfMonth();
        int month1= mStartDp.getMonth();
        int year1 = mStartDp.getYear();
        Calendar cal1 = Calendar.getInstance();
        cal1.set(Calendar.YEAR, year1);
        cal1.set(Calendar.MONTH, month1);
        cal1.set(Calendar.DAY_OF_MONTH, day1);


        int day2  = mEndDp.getDayOfMonth();
        int month2= mEndDp.getMonth();
        int year2 = mEndDp.getYear();
        Calendar cal2 = Calendar.getInstance();
        cal2.set(Calendar.YEAR, year2);
        cal2.set(Calendar.MONTH, month2);
        cal2.set(Calendar.DAY_OF_MONTH, day2);

        if(cal2.getTimeInMillis()>=cal1.getTimeInMillis()){
            dialog.dismiss();
            Log.i("Dialog", "Dismiss");
            // Condition is satisfied so do dialog dismiss
            }else {
            Log.i("Dialog", "Do not Dismiss");
            // Condition is not satisfied so do not dialog dismiss
        }

    }
}

Done

这可能是一个很晚的回复，但使用setCancelable就可以了。

alertDial.setCancelable(false);

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.

    }

});

如果您正在使用DialogFragment，这是处理Dialog的推荐方法。

AlertDialog的setButton（）方法（我认为AlertDialogBuilder的setPositiveButton（（）和setNegativeButton（）也是如此）所发生的事情是，您使用它设置的按钮（例如AlertDialog.button_POSITIVE）在按下时实际上会触发两个不同的OnClickListener对象。

第一个是DialogInterface.OnClickListener，它是setButton（）、setPositiveButton（（）和setNegativeButton（）的参数。

另一个是View.OnClickListener，它将被设置为在按下任何按钮时自动关闭AlertDialog，并且由AlertDialog自身设置。

您可以做的是使用带有null的setButton（）作为DialogInterface.OnClickListener来创建按钮，然后在View.OnClick Listener中调用自定义操作方法。例如，

@Override
public Dialog onCreateDialog(Bundle savedInstanceState)
{
    AlertDialog alertDialog = new AlertDialog(getActivity());
    // set more items...
    alertDialog.setButton(AlertDialog.BUTTON_POSITIVE, "OK", null);

    return alertDialog;
}

然后，您可以在DialogFragment的onResume（）方法中重写默认AlertDialog的按钮View.OnClickListener（否则将关闭对话框）：

@Override
public void onResume()
{
    super.onResume();
    AlertDialog alertDialog = (AlertDialog) getDialog();
    Button okButton = alertDialog.getButton(AlertDialog.BUTTON_POSITIVE);
    okButton.setOnClickListener(new View.OnClickListener() { 
        @Override
        public void onClick(View v)
        {
            performOkButtonAction();
        }
    });
}

private void performOkButtonAction() {
    // Do your stuff here
}

您需要在onResume（）方法中设置此值，因为getButton（）将返回null，直到显示对话框！

这将导致您的自定义操作方法只被调用一次，默认情况下对话框不会被关闭。

为DialogFragment使用自定义布局，并在内容下添加LinearLayout，该布局可以设置为无边框，以匹配Google Material Design。然后找到新创建的按钮并覆盖其OnClickListener。

例子：

public class AddTopicFragment extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        // Get the layout inflater
        LayoutInflater inflater = getActivity().getLayoutInflater();
        final View dialogView = inflater.inflate(R.layout.dialog_add_topic, null);

        Button saveTopicDialogButton = (Button) dialogView.findViewById(R.id.saveTopicDialogButton);
        Button cancelSaveTopicDialogButton = (Button) dialogView.findViewById(R.id.cancelSaveTopicDialogButton);

        final AppCompatEditText addTopicNameET = (AppCompatEditText) dialogView.findViewById(R.id.addTopicNameET);
        final AppCompatEditText addTopicCreatedByET = (AppCompatEditText) dialogView.findViewById(R.id.addTopicCreatedByET);

        saveTopicDialogButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // validate inputs
                if(addTopicNameET.getText().toString().trim().isEmpty()){
                    addTopicNameET.setError("Topic name can't be empty");
                    addTopicNameET.requestFocus();
                }else if(addTopicCreatedByET.getText().toString().trim().isEmpty()){
                    addTopicCreatedByET.setError("Topic created by can't be empty");
                    addTopicCreatedByET.requestFocus();
                }else {
                    // save topic to database
                    Topic topic = new Topic();
                    topic.name = addTopicNameET.getText().toString().trim();
                    topic.createdBy = addTopicCreatedByET.getText().toString().trim();
                    topic.createdDate = new Date().getTime();
                    topic.save();
                    AddTopicFragment.this.dismiss();
                }
            }
        });

        cancelSaveTopicDialogButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                AddTopicFragment.this.dismiss();
            }
        });

        // Inflate and set the layout for the dialog
        // Pass null as the parent view because its going in the dialog layout
        builder.setView(dialogView)
               .setMessage(getString(R.string.add_topic_message));

        return builder.create();
    }

}
