Android CountDownTimer 和 AlertDialog

Question

我希望在 CountDownTimer 完成后显示 AlertDialog，但是当我尝试这样做时出现错误。有没有人有解决方案或更好的方法？

{
new CountDownTimer(60000, 1000) {

 public void onTick(long millisUntilFinished) {
 mTextField.setText(":" + millisUntilFinished / 1000);
 }
 public void onFinish() {
 mTextField.setText("GAME OVER");
 mTextField.setTextSize(50);

     AlertDialog.Builder ADB = new AlertDialog.Builder(getApplicationContext());
     ADB.setTitle("GAME OVER")
        .setMessage(R.string.app_name)
        .setNeutralButton("PRESS BACK AND START GAME TO PLAY AGAIN", null)
        .show();
 }
    }.start();
}

Answer 1

实际上你的代码是完美的我运行它但替换

 AlertDialog.Builder ADB = new AlertDialog.Builder(getApplicationContext());

由用你的 Activity 名称替换游戏

 AlertDialog.Builder ADB = new AlertDialog.Builder(Game.this);
