java - 动画后我无法清除我的 ImageView

Question

我无法让图像消失或从 Activity 中清除它

启动器 Activity :-logo 是声明的 imageview

 Animation img = AnimationUtils.loadAnimation(getApplicationContext(),R.anim.fade);
logo.startAnimation(img);
if(logo.getImageAlpha()==0.1) {
    logo.setImageDrawable(null);
}

fade.xml:-

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"    >
<alpha
    android:duration="4000"
    android:fromAlpha="1.0"
    android:toAlpha="0.0"/>

</set>

我以为 ImageView 会被清除，但事实并非如此。我想要一些方法让 ImageView 在动画结束时消失

没有试过，但我认为它可能会起作用。试试这个:

Animation img = AnimationUtils.loadAnimation(context, R.anim.fade); //no need to use getApplicationContext I think
logo.startAnimation(img);

img.setAnimationListener(new Animation.AnimationListener(){
@Override
public void onAnimationStart(Animation arg0) {
}           
@Override
public void onAnimationRepeat(Animation arg0) {
}           
@Override
public void onAnimationEnd(Animation arg0) {
   //try to clear the image here
   logo.setImageDrawable(null);

   //or you can make the imageview to invisible
   logo.setVisibility(View.INVISIBLE);
}
});
