android - OnAnimationEnd 不起作用，是的，我研究过

Question

我在读一本书“Pragmatics: Hello Android”并逐字复制代码，语法都是正确的，因为我没有收到任何错误，但它没有按照我告诉它在 onAnimationEnd 上执行的操作执行。它应该带我去我的下一个 Activity ，但因为那不起作用我改变了它变成像 txtView.setText("ggag") 这样简单的东西只是为了看看它是否在执行……我注意到这本书讲述它的方式略有不同……

    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

    }


    });

是的，我的 onAnimationEnd 代码从未执行过 :(

Answer 1

你调用 fadein.start() 了吗？

onAnimationStart() 中的代码(例如记录消息)是否运行？
