待机页面功能

public class CountTimer extends CountDownTimer {
    private Context context;

    
    public CountTimer(long millisInFuture, long countDownInterval, Context context) {
        super(millisInFuture, countDownInterval);
        this.context = context;
    }

    // 计时完毕时触发
    @Override
    public void onFinish() {
        context.startActivity(new Intent(context, MainActivity.class));

    }


    // 计时过程显示
    @Override
    public void onTick(long millisUntilFinished) {
    }
}

 下面的写页面里面

public class baseDispatchTouchActivity extends AppCompatActivity{
    private CountTimer countTimerView;
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        init();
    }
    private void timeStart(){
        new Handler(getMainLooper()).post(new Runnable() {
            @Override
            public void run() {
                countTimerView.start();
            }
        });
    }
    private void init() {
        //初始化CountTimer，设置倒计时为2分钟。
        countTimerView=new CountTimer(120000,1000,baseDispatchTouchActivity.this);
    }

    
    @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        switch (ev.getAction()){
            //获取触摸动作，如果ACTION_UP，计时开始。
            case MotionEvent.ACTION_UP:
                countTimerView.start();
                break;
            //否则其他动作计时取消
            default:countTimerView.cancel();
                break;
        }
        return super.dispatchTouchEvent(ev);
    }
    @Override
    protected void onPause() {
        super.onPause();
        countTimerView.cancel();
    }
    @Override
    protected void onResume() {

        super.onResume();
        timeStart();
    }
}
