图像在动画中消失

我正在创建一个动画,我的图像将转换为屏幕上的不同位置,然后逐渐淡入。我完成了翻译部分(见下文),但现在当我开始淡入淡出动画时,它会在一段时间内消失,然后重新开始。我想要逐渐显示图像逐渐消失......任何想法为什么会发生这种情况?

public static int moveTwo(AnimationListener activity, View apa, int animationmove)


Log.v("MOVETWO", "Started move2");
AnimationSet picMov2 = new AnimationSet(true);
picMov2.setAnimationListener(activity);
RotateAnimation rotate2 = new RotateAnimation(0, 0,
        Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF,
        0.5f);
// rotate1.setStartOffset(50);
rotate2.setDuration(2000);
picMov2.addAnimation(rotate2);
TranslateAnimation trans2 = new TranslateAnimation(-200, -400, 0, 0);
trans2.setDuration(2000);
picMov2.setFillAfter(true);
picMov2.addAnimation(trans2);
apa.startAnimation(picMov2);
animationmove = 3;
return animationmove;





public static int moveThree(AnimationListener activity, View apa, int animationmove)


AlphaAnimation fadein = new AlphaAnimation((float) 0.3, 1);//HERE THE IMAGE IS DISAPPEARING
fadein.setAnimationListener(activity);

fadein.setDuration(2000);
fadein.setFillAfter(true);
apa.startAnimation(fadein);
animationmove=4;
return animationmove;

只需要在同一个地方创建一个翻译动作,这样它就不会回到原来的位置

public static int moveThree(AnimationListener activity, View apa, int animationmove)
{
    Log.v("MOVETHREE", "Started move3");

    AnimationSet picMov3 = new AnimationSet(true);
    picMov3.setAnimationListener(activity);
    AlphaAnimation fadein = new AlphaAnimation((float) 0.4, 1);
    // rotate1.setStartOffset(50);
    fadein.setDuration(duration);
    picMov3.addAnimation(fadein);
    TranslateAnimation trans1 = new TranslateAnimation(-400, -400, 0, 0);
    trans1.setDuration(duration);
    picMov3.setFillAfter(true);
    picMov3.addAnimation(trans1);
    apa.startAnimation(picMov3);
