アプリケーションにカウントダウンタイマーを実装しました。正常に動作しています。今、ダイアログ ボックスのアクセス許可 (はいまたはいいえ) を使用してアプリに終了ボタンを実装しました。ユーザーが [はい] を押してから終了し、[いいえ] を押してゲームに戻ります。終了ボタンをクリックするとカウントダウンタイマーを一時停止し、ダイアログボックスのボタンなしで再開します。

これが私のコードです:-

public class QuestionActivity extends Activity implements OnClickListener{
    private Question currentQ;
    private GamePlay currentGame;
    public CountDownTimer counterTimer;
    private Button nextBtn1, nextBtn2, nextBtn3, nextBtn4, nextBtn5;


            @Override
            public void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.question);
                processScreen();
         }
                /**
         * Configure current game and get question
         */
         private void processScreen()
         {
        currentGame = ((Application)getApplication()).getCurrentGame();
        currentQ = currentGame.getNextQuestion();
        nextBtn1 = (Button) findViewById(R.id.answer1);
        nextBtn1.setEnabled(true);
        nextBtn1.setOnClickListener(this);
        nextBtn2 = (Button) findViewById(R.id.answer2);
        nextBtn2.setEnabled(true);
        nextBtn2.setOnClickListener(this);

        nextBtn5.setEnabled(true);
        nextBtn5.setOnClickListener(this);
        /**

         */
        setQuestions();

    }

こんにちは、そのようなことをしてください-

package com.example.dialogboxwithtimer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button btn = (Button) findViewById(R.id.button1);

        textTimer = (TextView) findViewById(R.id.textTimer);

        startButton = (Button) findViewById(R.id.btnStart);

    }

    public void alertMessage() {
        DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener() {

                switch (which) {
                case DialogInterface.BUTTON_POSITIVE:

                    Toast.makeText(MainActivity.this, "Yes Clicked",

                    break;

                case DialogInterface.BUTTON_NEGATIVE:
                    // No button clicked
                    // do nothing
                    startTime = SystemClock.uptimeMillis();
                    myHandler.postDelayed(updateTimerMethod, 0);

                    Toast.makeText(MainActivity.this, "No Clicked",
                            Toast.LENGTH_LONG).show();
                    break;
                }
            }
        };

        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setMessage("Are you sure?")
                .setPositiveButton("Yes", dialogClickListener)
                .setNegativeButton("No", dialogClickListener).show();
    }

    private Runnable updateTimerMethod = new Runnable() {

        public void run() {
            timeInMillies = SystemClock.uptimeMillis() - startTime;
            finalTime = timeSwap + timeInMillies;

            int seconds = (int) (finalTime / 1000);

            myHandler.postDelayed(this, 0);
        }

    };

}

そして、あなたのレイアウトで-

    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

    <Button
        android:id="@+id/button1"
        android:layout_width="fill_parent"

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"

        <TextView
