android - 如何在android中通过viewflipper翻转 View ？

Question

在 android 应用程序中，我使用两个 View 翻转器来翻转 View 。我想提供翻转 View 之间的延迟。我正在调用 View 翻转器上的单击处理程序。这是我的代码。

@Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.oldmactwo);

            flipper = (ViewFlipper) findViewById(R.id.jetViewflipper);
            flippercow=(ViewFlipper) findViewById(R.id.cowViewflipper);

            flippercow.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
        Toast.makeText(getApplicationContext(), "on click method call",Toast.LENGTH_SHORT).show();              

        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
                    flipper.setInAnimation(inFromLeftAnimation());
                    flipper.setOutAnimation(outToLeftAnimation());
                    flipper.showPrevious();

                    try {
                        Thread.sleep(1000);
                    } catch (InterruptedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    /*Thread splashThread=new Thread()
                    {
                        public void run() {
                            try {
                                sleep(5000);
                            } catch (InterruptedException e) {
                                // TODO: handle exception
                            }
                            finally{
                                //splashThread.stop();
                            }

                        };
                    };
                    splashThread.start();*/

    Toast.makeText(getApplicationContext(), "delay ends",Toast.LENGTH_SHORT).show();                
                    //getcowFlipper();              
                    flippercow.setInAnimation(inFromBottomAnimation());
                    flippercow.setOutAnimation(outToTopAnimation());
                    flippercow.showNext();
                    //flipper.showPrevious();
    Toast.makeText(getApplicationContext(), "method ends",Toast.LENGTH_SHORT).show();               

                }
            });
     }

在上面的代码中，先执行延迟，然后再执行 View 翻转。

Answer 1

您的 inFromLeftAnimation() + inFromRightAnimation() + outFromLeftAnimation() + outFromRightAnimation() 方法包含如下部分:

inFromLeft.setDuration(400);

以上部分会产生 400 毫秒的延迟。当然你也有 inFromRight，outFromLeft 等。

例子:

    private Animation inFromLeftAnimation() 
    {
      Animation inFromLeft = new TranslateAnimation(
      Animation.RELATIVE_TO_PARENT,  -1.0f, Animation.RELATIVE_TO_PARENT,  0.0f,
      Animation.RELATIVE_TO_PARENT,  0.0f, Animation.RELATIVE_TO_PARENT,   0.0f);

      inFromLeft.setDuration(400);
      inFromLeft.setInterpolator(new AccelerateInterpolator());
      return inFromLeft;
    }
