推荐答案

您要处理的确定事件，并执行一些动作。

you want to handle the "Ok" event and perform some action.

您必须处理对话框的方法。

You have a method to handle the dialog.

public void displayAlertToChangeActivity(){
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("title");
alert.setMessage("massage");

alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
  public void onClick(DialogInterface dialog, int whichButton) {
   //Do something here where "ok" clicked and then perform intent from activity context
   Intent intent = new Intent(MyActivity.this, MyNextActivity.class);
   MyActivity.this.startActivity(intent);

}
});

alert.show();

}
