Question

在我的应用中，我的倒计时从五点到一点。此时，只要活动开始，计数器就会启动。我想要的是保持5秒钟并等待倒计时直到触摸屏幕。因此倒计时器应该启动触摸事件。

    public class MainActivity extends Activity implements OnGestureListener {
    private static final String FORMAT = "%02d:%02d";

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

        new CountDownTimer(5000, 10) {
            public void onTick(long millisUntilFinished) {
                text.setText("" + String.format("%02d:%03d",
                        TimeUnit.MILLISECONDS.toSeconds(millisUntilFinished) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished)),
                        TimeUnit.MILLISECONDS.toMillis(millisUntilFinished) - TimeUnit.SECONDS.toMillis(TimeUnit.MILLISECONDS.toSeconds(millisUntilFinished))
                ));

                if (animationRunning) {
                    cancel();
                }
            }

            public void onFinish() {
                text.setText("done!");
            }
        }.start();
    }


    @Override
    public boolean onTouchEvent(MotionEvent touchevent) {

    }
}

将倒数计时器放在onTouch内，如下所示

public class MainActivity extends Activity implements OnGestureListener {
    private static final String FORMAT = "%02d:%02d";

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


    }


    @Override
    public boolean onTouchEvent(MotionEvent touchevent) {
        new CountDownTimer(5000, 10) {
            public void onTick(long millisUntilFinished) {
                text.setText("" + String.format("%02d:%03d",
                        TimeUnit.MILLISECONDS.toSeconds(millisUntilFinished) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished)),
                        TimeUnit.MILLISECONDS.toMillis(millisUntilFinished) - TimeUnit.SECONDS.toMillis(TimeUnit.MILLISECONDS.toSeconds(millisUntilFinished))
                ));

                if (animationRunning) {
                    cancel();
                }
            }

            public void onFinish() {
                text.setText("done!");
            }
        }.start();
    }
}

将此部分代码移至onTouchEvent，因为它在活动创建时就是为什么它在您的活动开始时启动

你应该没事

android - 启动onTouch活动
