试试这个:

AlertDialog.Builder builder = new AlertDialog.Builder(this);

builder.setTitle("Confirm");
builder.setMessage("Are you sure?");

builder.setPositiveButton("YES", new DialogInterface.OnClickListener() {

    public void onClick(DialogInterface dialog, int which) {
        // Do nothing but close the dialog

        dialog.dismiss();
    }
});

builder.setNegativeButton("NO", new DialogInterface.OnClickListener() {

    @Override
    public void onClick(DialogInterface dialog, int which) {

        // Do nothing
        dialog.dismiss();
    }
});

AlertDialog alert = builder.create();
alert.show();

试试这个:

AlertDialog.Builder builder = new AlertDialog.Builder(this);

builder.setTitle("Confirm");
builder.setMessage("Are you sure?");

builder.setPositiveButton("YES", new DialogInterface.OnClickListener() {

    public void onClick(DialogInterface dialog, int which) {
        // Do nothing but close the dialog

        dialog.dismiss();
    }
});

builder.setNegativeButton("NO", new DialogInterface.OnClickListener() {

    @Override
    public void onClick(DialogInterface dialog, int which) {

        // Do nothing
        dialog.dismiss();
    }
});

AlertDialog alert = builder.create();
alert.show();

AlertDialog。Builder真的没有那么难用。一开始肯定有点吓人，但一旦你使用了一点，它就变得简单而强大了。我知道你说过你知道如何使用它，但这里只是一个简单的例子:

DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        switch (which){
        case DialogInterface.BUTTON_POSITIVE:
            //Yes button clicked
            break;

        case DialogInterface.BUTTON_NEGATIVE:
            //No button clicked
            break;
        }
    }
};

AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setMessage("Are you sure?").setPositiveButton("Yes", dialogClickListener)
    .setNegativeButton("No", dialogClickListener).show();

你也可以重用那个DialogInterface。OnClickListener如果你有其他是/否框，应该做同样的事情。

如果你是从视图中创建对话框。OnClickListener，你可以使用view.getContext()来获取Context。或者你也可以使用yourFragmentName.getActivity()。

1.创建AlertDialog，设置消息、标题和正面、负面按钮:

final AlertDialog alertDialog = new AlertDialog.Builder(this)
                        .setCancelable(false)
                        .setTitle("Confirmation")
                        .setMessage("Do you want to remove this Picture?")
                        .setPositiveButton("Yes",null)
                        .setNegativeButton("No",null)
                        .create();

2.现在在DialogInterface上找到两个按钮，然后单击setOnClickListener():

alertDialog.setOnShowListener(new DialogInterface.OnShowListener() {
            @Override
            public void onShow(DialogInterface dialogInterface) {
                Button yesButton = (alertDialog).getButton(android.app.AlertDialog.BUTTON_POSITIVE);
                Button noButton = (alertDialog).getButton(android.app.AlertDialog.BUTTON_NEGATIVE);
                yesButton.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        //Now Background Class To Update Operator State
                        alertDialog.dismiss();
                        Toast.makeText(GroundEditActivity.this, "Click on Yes", Toast.LENGTH_SHORT).show();
                        //Do Something here 
                    }
                });

                noButton.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        alertDialog.dismiss();
                        Toast.makeText(GroundEditActivity.this, "Click on No", Toast.LENGTH_SHORT).show();
                        //Do Some Thing Here 
                    }
                });
            }
        });

3.To 显示警报对话框：

alertDialog.show();

注意:不要忘记AlertDialog的Final Keyword。

AlertDialog.Builder altBx = new AlertDialog.Builder(this);
    altBx.setTitle("My dialog box");
    altBx.setMessage("Welcome, Please Enter your name");
    altBx.setIcon(R.drawable.logo);

    altBx.setPositiveButton("Ok", new DialogInterface.OnClickListener()
    {
      public void onClick(DialogInterface dialog, int which)
      {
          if(edt.getText().toString().length()!=0)
          {
              // Show any message
          }
          else 
          {

          }
      }
    });
    altBx.setNeutralButton("Cancel", new DialogInterface.OnClickListener()
    {
      public void onClick(DialogInterface dialog, int which)
      {
          //show any message
      }

    });
  altBx.show();  

芬兰湾的科特林的实现。

你可以像这样创建一个简单的函数:

fun dialogYesOrNo(
        activity: Activity,
        title: String,
        message: String,
        listener: DialogInterface.OnClickListener
    ) {
        val builder = AlertDialog.Builder(activity)
        builder.setPositiveButton("Yes", DialogInterface.OnClickListener { dialog, id ->
            dialog.dismiss()
            listener.onClick(dialog, id)
        })
        builder.setNegativeButton("No", null)
        val alert = builder.create()
        alert.setTitle(title)
        alert.setMessage(message)
        alert.show()
    }

像这样叫它:

dialogYesOrNo(
  this,
  "Question",
  "Would you like to eat?",
  DialogInterface.OnClickListener { dialog, id ->
    // do whatever you need to do when user presses "Yes"
  }
})
