Question

我在点击按钮上显示了一个布局。我希望在10秒后隐藏该布局。

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    mVolHandler = new Handler();
    mVolRunnable = new Runnable() {
        public void run() {
            mVolLayout.setVisibility(View.GONE);
        }
    };
}


private OnTouchListener mVolPlusOnTouchListener = new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        mVolLayout.setVisibility(View.VISIBLE);
        mVolHandler.postDelayed(mVolRunnable, 10000);
    }
}

Answer 1

利用Handler＆amp; Runnable。

您可以使用Handler的postDelayed来延迟Runnable。

Runnable mRunnable;
Handler mHandler=new Handler();

mRunnable=new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                yourLayoutObject.setVisibility(View.INVISIBLE); //If you want just hide the View. But it will retain space occupied by the View.
                yourLayoutObject.setVisibility(View.GONE); //This will remove the View. and free s the space occupied by the View    
            }
        };

现在在onButtonClick事件中你必须告诉Handler在X毫秒后运行一个runnable：

mHandler.postDelayed(mRunnable,10*1000);

如果您想取消此操作，则必须使用mHandler.removeCallbacks(mRunnable);

更新（根据编辑问题） 您只需要使用removeCallbacks()

从Handler中删除回调

所以只需在onTouch方法中更新您的代码，如下所示：

mVolLayout.setVisibility(View.VISIBLE);
mVolHandler.removeCallbacks(mVolRunnable);
mVolHandler.postDelayed(mVolRunnable, 10000);

单击按钮时，您可以使用Animation启动，持续时间为10秒，淡出布局，并可能在最后将其可见性设置为GONE。

Answer 3

以下代码会在3秒内隐藏您的布局。您可以通过更改此处为延迟更改的常量来更改时间。

         private void HideLayout() {

     final View view=volume_control_layout;
     view.postDelayed(new Runnable() {

        public void run() {
            if(!volume_controller.isPressed())
            {
            view.setVisibility(View.INVISIBLE);
            }
            else
            {
                HideLayout();
            }
        }
    }, 3000); // (3000 == 3secs)

    }

使用处理程序在10秒后隐藏布局。使用后延迟方法

    public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    pd=ProgressDialog.show(this,"","Loading, Please wait .. ",true);

    setTitle("set title");
    final Handler uiThreadCallback=new Handler();
    final Runnable runInUIThread= new Runnable(){
        public void run(){
            fnDraw();
            pd.dismiss();

        }
    }; 
    new Thread(){
        @Override public void run(){
            uiThreadCallback.post(runInUIThread);
        }
    }.start();
}
public void fnDraw(){
    setContentView(R.layout.define ur xml if any);
    i1=(ImageView)findViewById(R.id.i1);
    t1=(TextView)findViewById(R.id.t1);
    t2=(TextView)findViewById(R.id.t2);

    timerRegister=new Timer();
    lIteration=0;
    checkTime=new TimerTask(){
        public void run(){
            if(lIteration==1){
                timerRegister.cancel();
                uiDrawThreadCallback.post(runInUIDrawThread);
            }
            lIteration++;
            return;
        }
    };
    timerRegister.scheduleAtFixedRate(checkTime,0,10000);
}
final Handler uiDrawThreadCallback=new Handler();
final Runnable runInUIDrawThread= new Runnable(){
    @Override
    public void run(){
        fnDrawAgain();
    }
};
public void fnDrawAgain(){
    Intent intent=new Intent(this,new class you want to open.class);
    startActivity(intent);
}

}

尝试一下，我确信它会在你的创建屏幕上运行

以上都不是好的解决方案。想象一下，10s后视图不可见（例如：它向下滚动），因此Visibility.GONE将无法使用它。我仍在寻找解决方案
