我试图做一个转换的动画从底部到屏幕中间的图像视图。一旦动画完成，我想要的图像视图呆在那里。我不想让setFillAfter（真），因为我想要的ImageView的实际位置进行更新。

我这样做，目前有2图像视图（一个在动画的起点和一个底），我与setVisibility玩到实现这一目标。这是做事情的正确方法？这里是code我用：

 ＆LT; ImageView的
    机器人：ID =@ + ID / ivStart
    机器人：layout_width =WRAP_CONTENT
    机器人：layout_height =WRAP_CONTENT
    机器人：layout_alignParentBottom =真
    机器人：layout_alignParentRight =真
    机器人：背景=@可绘制/ typer_step_1
    机器人：重力=中心
     /＆GT;



＆LT; ImageView的
    机器人：ID =@ + ID / ivMiddle
    机器人：layout_width =WRAP_CONTENT
    机器人：layout_height =WRAP_CONTENT
    机器人：layout_alignParentRight =真
    机器人：layout_centerVertical =真
    机器人：背景=@可绘制/ typer_step_1
    机器人：重力=中心
    机器人：能见度=隐形
     /＆GT;








     TranslateAnimation翻译=新TranslateAnimation（0，mDestLoc1 [0] -mSrcLoc1 [0]，0，mDestLoc1 [1] -mSrcLoc1 [1]）;
translate.setDuration（2000）;
translate.setAnimationListener（新AnimationListener（）{

    @覆盖
    公共无效onAnimationStart（动画动画）{}

    @覆盖
    公共无效onAnimationEnd（动画动画）{
        ivMiddle.setVisibility（View.VISIBLE）
                        ivStart.setVisibility（View.INVISIBLE）


    }

    @覆盖
    公共无效onAnimationRepeat（动画动画）{}

}）;

ivStart.startAnimation（翻译）;
 

解决方案

那么你必须树立新的的LayoutParams 为您查看该动画。当动画完成，在你的 onAnimationEnd 部分，设置新的位置的查看。

  TranslateAnimation翻译=新TranslateAnimation（0，mDestLoc1 [0] -mSrcLoc1 [0]，0，mDestLoc1 [1] -mSrcLoc1 [1]）;
     translate.setDuration（2000）;
     translate.setAnimationListener（新AnimationListener（）{

         @覆盖
         公共无效onAnimationStart（动画动画）{}

         @覆盖
         公共无效onAnimationEnd（动画动画）{
             RelativeLayout.LayoutParams面值=新RelativeLayout.LayoutParams（LayoutParams.WRAP_CONTENT，LayoutParams.WRAP_CONTENT）;
             par.topMargin = mDestLoc1 [1] -mSrcLoc1 [1];
             par.leftMargin = mDestLoc1 [0] -mSrcLoc1 [0];
             view.setLayoutParams（PAR）;
         }

         @覆盖
         公共无效onAnimationRepeat（动画动画）{}

     }）;

     view.startAnimation（翻译）;
 

I am trying to to do a translate animation on an image view from the bottom to the middle of the screen. Upon finish of the animation, I want the image view to stay there. I dont want the setFillAfter(true) because I want the actual position of the imageview to be updated.

I do it currently by having 2 image view (one at the start of animation and one at the end) and I play with the setVisibility to achieve this. Is this the correct way to do things? Here is the code I used:

<ImageView
    android:id="@+id/ivStart"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"
    android:background="@drawable/typer_step_1"
    android:gravity="center"
     />



<ImageView
    android:id="@+id/ivMiddle"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:layout_centerVertical="true"
    android:background="@drawable/typer_step_1"
    android:gravity="center"
    android:visibility="invisible"
     />    








     TranslateAnimation translate = new TranslateAnimation(0, mDestLoc1[0]-mSrcLoc1[0], 0, mDestLoc1[1]-mSrcLoc1[1]);                   
translate.setDuration(2000);
translate.setAnimationListener(new AnimationListener(){

    @Override
    public void onAnimationStart(Animation animation) {}

    @Override
    public void onAnimationEnd(Animation animation) {
        ivMiddle.setVisibility(View.VISIBLE)
                        ivStart.setVisibility(View.INVISIBLE)


    }

    @Override
    public void onAnimationRepeat(Animation animation) {}

});

ivStart.startAnimation(translate);

Then you must set new LayoutParams for your View which is animating. When animation finishes, in your onAnimationEnd part, set new position of your View.

     TranslateAnimation translate = new TranslateAnimation(0, mDestLoc1[0]-mSrcLoc1[0], 0, mDestLoc1[1]-mSrcLoc1[1]);                   
     translate.setDuration(2000);
     translate.setAnimationListener(new AnimationListener(){

         @Override
         public void onAnimationStart(Animation animation) {}

         @Override
         public void onAnimationEnd(Animation animation) {
             RelativeLayout.LayoutParams par = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
             par.topMargin = mDestLoc1[1]-mSrcLoc1[1];
             par.leftMargin = mDestLoc1[0]-mSrcLoc1[0];
             view.setLayoutParams(par);              
         }

         @Override
         public void onAnimationRepeat(Animation animation) {}

     });

     view.startAnimation(translate);
