android - 如何像fb图像一样缩放地图？

Question

我显示此链接以缩放图像http://developer.android.com/training/animation/zoom.html

我想尝试我的地图片段：当我点击隐藏地图时，地图应该最大化，然后再次点击最小化地图，使用类似http://developer.android.com/training/animation/zoom.html的动画

public class MainActivity extends FragmentActivity {
private LinearLayout layout;
private LinearLayout layoutmap;
private TextView search_txt_hide_map;
boolean hide = false;
private Animator mCurrentAnimator;

private int mShortAnimationDuration;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    layout = (LinearLayout) findViewById(R.id.search_lin_search_list);
    layoutmap = (LinearLayout) findViewById(R.id.search_lin_map);
    search_txt_hide_map = (TextView) findViewById(R.id.search_txt_hide_map);

    search_txt_hide_map.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            if (hide) {
                hide = false;
                zoomImageFromThumb();

            } else {
                hide = true;
                zoomImageFromThumb();

            }

        }
    });

     }

 private void zoomImageFromThumb() {

    if (mCurrentAnimator != null) {
        mCurrentAnimator.cancel();
    }

    final LinearLayout expandedImageView =layoutmap;
    layout.setVisibility(View.GONE);

    final Rect startBounds = new Rect();

    finalBounds.offset(-globalOffset.x, -globalOffset.y);

    float startScale;
    if ((float) finalBounds.width() / finalBounds.height()
            > (float) startBounds.width() / startBounds.height()) {
        startScale = (float) startBounds.height() / finalBounds.height();
        float startWidth = startScale * finalBounds.width();
        float deltaWidth = (startWidth - startBounds.width()) / 2;
        startBounds.left -= deltaWidth;
        startBounds.right += deltaWidth;
    } else {
        startScale = (float) startBounds.width() / finalBounds.width();
        float startHeight = startScale * finalBounds.height();
        float deltaHeight = (startHeight - startBounds.height()) / 2;
        startBounds.top -= deltaHeight;
        startBounds.bottom += deltaHeight;
    }

    expandedImageView.setVisibility(View.VISIBLE);

    expandedImageView.setPivotX(0f);
    expandedImageView.setPivotY(0f);

    AnimatorSet set = new AnimatorSet();
    set
            .play(ObjectAnimator.ofFloat(expandedImageView, View.X, startBounds.left,

    set.setDuration(mShortAnimationDuration);
    set.setInterpolator(new DecelerateInterpolator());
    set.addListener(new AnimatorListenerAdapter() {
        @Override
        public void onAnimationEnd(Animator animation) {
            mCurrentAnimator = null;
        }

        @Override
        public void onAnimationCancel(Animator animation) {
            mCurrentAnimator = null;
        }
    });
    set.start();
    mCurrentAnimator = set;

    final float startScaleFinal = startScale;
    expandedImageView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if (mCurrentAnimator != null) {
                mCurrentAnimator.cancel();
            }

            AnimatorSet set = new AnimatorSet();
            set
                    .play(ObjectAnimator.ofFloat(expandedImageView, View.X, startBounds.left))
                    .with(ObjectAnimator.ofFloat(expandedImageView, View.Y, startBounds.top))

                            .ofFloat(expandedImageView, View.SCALE_X, startScaleFinal))
                    .with(ObjectAnimator
                            .ofFloat(expandedImageView, View.SCALE_Y, startScaleFinal));
            set.setDuration(mShortAnimationDuration);
            set.setInterpolator(new DecelerateInterpolator());
            set.addListener(new AnimatorListenerAdapter() {
                @Override
                public void onAnimationEnd(Animator animation) {
                    expandedImageView.setVisibility(View.GONE);
                    mCurrentAnimator = null;
                }

                @Override
                public void onAnimationCancel(Animator animation) {
                    expandedImageView.setVisibility(View.GONE);
                    mCurrentAnimator = null;

            });
            set.start();
            mCurrentAnimator = set;
        }
    });
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

}

这是我的xml：
