实现一个图片位移动画

        final int[] location = new int[2];
        v.getLocationOnScreen(location);

        int screenWidth = mShaPreferences.getInt("screenWidth", 0);
        int screenHeight = mShaPreferences.getInt("screenHeight", 0);

        FrameLayout.LayoutParams params = (android.widget.FrameLayout.LayoutParams) mImageAnim
                .getLayoutParams();
        params.topMargin = location[1] - Util.px2dip(mContext, 20);
        params.leftMargin = screenWidth / 6;
        mImageAnim.setLayoutParams(params);
        mImageAnim.setVisibility(View.VISIBLE);

        int endX = screenWidth - Util.px2dip(mContext, 30);
        int endY = screenHeight - Util.px2dip(mContext, 20);

        AnimationSet set = new AnimationSet(false);
        TranslateAnimation translateAnimationX = new TranslateAnimation(0,
                endX, 0, 0);
        translateAnimationX.setInterpolator(new LinearInterpolator());
        translateAnimationX.setRepeatCount(0);
        TranslateAnimation translateAnimationY = new TranslateAnimation(0, 0,
                0, endY);
        translateAnimationY.setInterpolator(new AccelerateInterpolator());
        translateAnimationY.setRepeatCount(0);

        set.setAnimationListener(new Animation.AnimationListener() {
            @Override
            public void onAnimationStart(Animation animation) {
            }

            @Override
            public void onAnimationRepeat(Animation animation) {
            }

            @Override
            public void onAnimationEnd(Animation animation) {
                mImageAnim.setVisibility(View.GONE);
            }
        });

        set.addAnimation(translateAnimationY);
        set.addAnimation(translateAnimationX);
        set.setDuration(500);

        mImageAnim.startAnimation(set);
