淡入只发生在第一个动画android

Question

我正在创建一个动画，其中有3个图像将在整个屏幕上生成动画。当中间图像到达屏幕中间时，它将淡入。

一切工作正常，只有当第一个图像碰到中间时它正在淡入，当第二个和第三个图像碰到中间时，它们不会退色in。

每张图片都有自己的视图。并在所有相同的视图上执行淡入方法。

请参阅下面的代码。让我知道你是否需要更多信息。

以下是模拟幻灯片在屏幕上移动的过程。 moveThree是动画淡入淡出。 moveOne和moveTwo是屏幕上图像的翻译。

public static int secondProcess(AnimationListener activity, View apa1,View apa2, View apa3,int animationmove) 
{ 
    Log.d("2", "SECOND PROCESS"); 
    moveOne(activity, apa2); 
    moveTwo(activity,apa1); 
    animationmove = 3; 
    return animationmove; 

} 

public static int thirdProcess(AnimationListener activity, View apa1,View apa2,View apa3, int animationmove) 
{ 
    Log.d("3", "THIRD PROCESS"); 
    moveThree(activity,apa1); 
    animationmove = 4; 
    return animationmove; 
} 

public static int fourthProcess(AnimationListener activity, View apa1, View apa2,View apa3,int animationmove) 
{ 
    Log.d("4", "FOURTH PROCESS"); 
    moveOne(activity, apa3); 
    moveTwo(activity, apa2); 
    moveFour(activity,apa1); 
    animationmove = 5; 
    return animationmove; 

} 


public static int fifthProcess(AnimationListener activity, View apa1,View apa2,View apa3, int animationmove) 
{ 
    Log.d("5", "FIFTH PROCESS"); 
    moveThree(activity,apa2);//IN THE SECOND VIEW HERE THE IMAGE IS NOT FADING 
    animationmove = 6; 
    return animationmove; 

} 

moveThree方法：

private static void moveThree(AnimationListener activity, View apa) 
{ 
    Log.v("MOVETHREE", "Started move3"); 
    AnimationSet picMov3 = new AnimationSet(true); 
    picMov3.setAnimationListener(activity); 
    AlphaAnimation fadein = new AlphaAnimation((float) 0.3, 1); 
    fadein.setFillAfter(true); 

    fadein.setDuration(duration); 
    picMov3.addAnimation(fadein); 
    TranslateAnimation trans1 = new TranslateAnimation(-500, -500, 0, 0); 
    trans1.setDuration(duration); 
    picMov3.setFillAfter(true); 
    picMov3.setInterpolator(interpolator); 
    picMov3.addAnimation(trans1); 

    apa.startAnimation(picMov3); 


} 

Answer 1

你只调用moveThree第一个视图。您还需要打电话，如果其他意见：

moveThree(activity,apa1); 
moveThree(activity,apa2); 
moveThree(activity,apa3);
