Answer 1

public void openDialog(View view){
  AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
  alertDialogBuilder.setMessage("Are you sure,You wanted to make decision");

  alertDialogBuilder.setPositiveButton("yes", new DialogInterface.OnClickListener() {
     @Override
     public void onClick(DialogInterface arg0, int arg1) {
        Toast.makeText(MainActivity.this,"You clicked yes button",Toast.LENGTH_LONG).show();
     }
  });

  alertDialogBuilder.setNegativeButton("No",new DialogInterface.OnClickListener() {
     @Override
     public void onClick(DialogInterface dialog, int which) {
        finish();
     }
  });

  AlertDialog alertDialog = alertDialogBuilder.create();
  alertDialog.show();

}

只要调用这个方法openDialog();在你的 setContentView(R.layout.activity_main); 之后例子

setContentView(R.layout.activity_main);
openDialog();
