java如何在单击按钮后停止“飞溅时间”？

Question

我有一个关于“原始”的视频

单击按钮进入下一个活动，但“飞溅时间”仍在计数

''Button btn_1; VideoView videoView2;

private static int SPLASH_TIME = 10000; // This is 10 seconds

 @Override
        protected void onCreate (Bundle savedInstanceState) {
            super.onCreate (savedInstanceState);
            setContentView (R.layout.activity_pub2);

        btn_1 = (Button) findViewById (R.id.line1);
        btn_1.setOnClickListener (new View.OnClickListener () {
            @Override
            public void onClick (View v) {
                Toast.makeText (Pub2.this, "BOOOOAAAAAA", Toast.LENGTH_SHORT) .show ();
                Intent orderDetail = new Intent (Pub2.this, Main2.class);
                startActivity (orderDetail);
            }
        });

videoView2 = (VideoView) findViewById (R.id.videoView2);
videoView2.setVideoURI (Uri.parse ("安卓.resource: //" + getPackageName () + "/" + R.raw.crop));

videoView2.requestFocus ();

videoView2.start ();

new Handler (). postDelayed (new Runnable () {
            @Override
            public void run () {
                // Do any action here. Now we are moving to next page
                Intent mySuperIntent = new Intent (Pub2.this, MainActivity.class);
                startActivity (mySuperIntent);
                finish ();
            }
        }, SPLASH_TIME);

我可以继续参加新活动，但在“SPLASH_TIME”结束后，SPLASH_TIME=10000； 打断并达到赋予它的意图

Intent mySuperIntent = new Intent (Pub2.this, MainActivity.class);
    startActivity (mySuperIntent);

Answer 1

通过调用handler.removeCallbacksAndMessages(null)停止处理程序。它将从处理程序中删除所有回调。在类中定义一个处理程序

 Handler mHandler= newHandler();
    void foo(){
    mHandler.postDelayed (new Runnable () {
            @Override
            public void run () {
                // Do any action here. Now we are moving to next page
                Intent mySuperIntent = new Intent (Pub2.this, MainActivity.class);
                startActivity (mySuperIntent);
                finish ();
            }
        }, SPLASH_TIME);
    }

   @Override onStop(){
       super.onStop();
       handler.removeCallbacksAndMessages(null);
   }

Answer 2

mVideoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
    @Override
    public void onCompletion(MediaPlayer mediaPlayer) {
                Intent mySuperIntent = new Intent (Pub2.this, MainActivity.class);
                startActivity (mySuperIntent);
                finish ();
    }
 });
