android - OnAnimationEnd不起作用，并且已经研究过

我正在读一本书“ Pragmatics：Hello Android”
并复制代码单词和语法都是正确的，因为我没有错误，但是它没有执行我在onAnimationEnd上告诉它的操作。它像txtView.setText（“ ggag”）这样简单
只是看它是否还在执行...而我注意到这本书的处理方式略有不同。

    Animation fadein = AnimationUtils.loadAnimation(this, R.anim.fade_in);
    fadein.setAnimationListener(new AnimationListener() { /*im thinking the problem is
     that it does all the work from within the setAnimationLIstener instead of like i
     have seen around where the methods onAnimationEnd , onAnimationRepeat are all
     done seprately outside of the
      setAnimationListener(new AnimationListener() {..all work is done here??... } */
     @Override
     public void onAnimationEnd(Animation animation) {
      //startActivity(new Intent(splahActivity.this,menuActivity.class));
      //the above line of code was not working so i added the line below
      //neither executes

                    TextView topLogo = (TextView)findViewById(R.id.lblTop);
      topLogo.setText("dfsgsdfg");

     }

    @Override
    public void onAnimationRepeat(Animation animation) {
      // TODO Auto-generated method stub

    }

    @Override
    public void onAnimationStart(Animation animation) {
     // TODO Auto-generated method stub

    }


    });

所以是的，我的onAnimationEnd代码永远不会执行:(

最佳答案

您是否调用了fadein.start（）？

onAnimationStart（）中的代码（例如记录一条消息）是否运行？
