试试下面的代码:

AlertDialog.Builder builder1 = new AlertDialog.Builder(context);
builder1.setMessage("Write your message here.");
builder1.setCancelable(true);

builder1.setPositiveButton(
    "Yes",
    new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {
            dialog.cancel();
        }
    });

builder1.setNegativeButton(
    "No",
    new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {
            dialog.cancel();
        }
    });

AlertDialog alert11 = builder1.create();
alert11.show();

试试下面的代码:

AlertDialog.Builder builder1 = new AlertDialog.Builder(context);
builder1.setMessage("Write your message here.");
builder1.setCancelable(true);

builder1.setPositiveButton(
    "Yes",
    new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {
            dialog.cancel();
        }
    });

builder1.setNegativeButton(
    "No",
    new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {
            dialog.cancel();
        }
    });

AlertDialog alert11 = builder1.create();
alert11.show();

在材质组件库中，你可以使用MaterialAlertDialogBuilder

   MaterialAlertDialogBuilder(context)
        .setMessage("Are you sure you want to delete this entry?")
        .setPositiveButton("Delete") { dialog, which ->
            // Respond to positive button press
        }
        .setNegativeButton("Cancel") { dialog, which ->
            // Respond to positive button press
        }   
        .show()

使用Compose 1.0。X你可以使用:

val openDialog = remember { mutableStateOf(true) }

if (openDialog.value) {
    AlertDialog(
        onDismissRequest = {
            // Dismiss the dialog when the user clicks outside the dialog or on the back
            // button. If you want to disable that functionality, simply use an empty
            // onCloseRequest.
            openDialog.value = false
        },
        title = null,
        text = {
            Text(
                "Are you sure you want to delete this entry?"
            )
        },
        confirmButton = {
            TextButton(
                onClick = {
                    openDialog.value = false
                }
            ) {
                Text("Delete")
            }
        },
        dismissButton = {
            TextButton(
                onClick = {
                    openDialog.value = false
                }
            ) {
                Text("Cancel")
            }
        }
    )
}

David Hedlund发布的代码给了我错误:

无法添加窗口-空令牌无效

如果你得到同样的错误，请使用下面的代码。它的工作原理!

runOnUiThread(new Runnable() {
    @Override
    public void run() {

        if (!isFinishing()){
            new AlertDialog.Builder(YourActivity.this)
              .setTitle("Your Alert")
              .setMessage("Your Message")
              .setCancelable(false)
              .setPositiveButton("ok", new OnClickListener() {
                  @Override
                  public void onClick(DialogInterface dialog, int which) {
                      // Whatever...
                  }
              }).show();
        }
    }
});

你可以试试这个....

    AlertDialog.Builder dialog = new AlertDialog.Builder(MainActivity.this);
dialog.setCancelable(false);
dialog.setTitle("Dialog on Android");
dialog.setMessage("Are you sure you want to delete this entry?" );
dialog.setPositiveButton("Delete", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int id) {
        //Action for "Delete".
    }
})
        .setNegativeButton("Cancel ", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
            //Action for "Cancel".
            }
        });

final AlertDialog alert = dialog.create();
alert.show();

你可以创建Activity并扩展AppCompatActivity。然后在清单中加入下一种风格

<activity android:name=".YourCustomDialog"
            android:theme="Theme.AppCompat.Light.Dialog">
</activity>

充气它的按钮和TextViews

然后把这个当做一个对话。

例如，在linearLayout中，我填充下一个参数:

android:layout_width="300dp"
android:layout_height="wrap_content"
