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();

使用Anko (Kotlin开发人员的官方库)，您可以简单地使用

alert("Alert title").show()

或者更复杂的:

alert("Hi, I'm Roy", "Have you tried turning it off and on again?") {
    yesButton { toast("Oh…") }
    noButton {}
}.show()

导入Anko:

implementation "org.jetbrains.anko:anko:0.10.8"

试试Kotlin

AlertDialog.Builder(this)
            .setTitle("Title")
            .setPositiveButton("Yes"){ dialog, which ->

            }
            .setNegativeButton("No", null)
            .setMessage("Your given alert message...")
            .show()

对我来说

new AlertDialog.Builder(this)
    .setTitle("Closing application")
    .setMessage("Are you sure you want to exit?")
    .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
          @Override
          public void onClick(DialogInterface dialog, int which) {

          }
     }).setNegativeButton("No", null).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")
            }
        }
    )
}
