Question

嗨我有这个带有图像网格列表的应用程序，我的想法是当用户点击其中一个图像时，浮动图像将显示在同一位置并激活到主图像持有者位置。我试过这样的东西，我在运行时添加一个视图并将其设置为性能不变，我的问题是复制在我的gridview中单击的相同img视图，并在onXouchLister上设置基于getX和getY的浮动位置，但是浮动图像没有显示用户触摸的位置和图像滞后，这是我的代码

 public class MainActivity extends ActionBarActivity implements OnClickListener,
        OnPageChangeListener, UpdateAvatarProgressListener, OnTouchListener {

      ViewGroup mParentView;

      float getX;
      float getY;

      @Override
      protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.fragment_edit);

        mParentView = (ViewGroup) findViewById(R.id.fragment_edit_id);
        img = new ImageView(MainActivity.this);     
        img.setVisibility(View.GONE);
        mParentView.addView(img);
        GridView gridView= (GridView) v.findViewById(R.id.img_gridview);
          gridView.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                 img = (ImageView) view.findViewById(R.id.image_holder);
                 img.setVisibility(View.VISIBLE);

      int[] img_coordinates = new int[2];
      mainImageHolder.getLocationOnScreen(img_coordinates);
      float x = (float) (img_coordinates[0] + mainImageHolder.getWidth() / 2.0);
      float y = (float) (img_coordinates[1] + mainImageHolder.getHeight() / 2.0);
      TranslateAnimation anim = new TranslateAnimation(getX, getY, x, y);
      anim.setDuration(800);

      anim.setAnimationListener(new TranslateAnimation.AnimationListener() {

        @Override
        public void onAnimationStart(Animation animation) {
        }

        @Override
        public void onAnimationRepeat(Animation animation) {
        }

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

      img.startAnimation(anim);
            }
        }
      }

      @Override
      public boolean onTouch(View v, MotionEvent event) {
        // TODO Auto-generated method stub
        getX = event.getX();
        getY = event.getY();
        return false;
      }
    }

我需要这样的link但是我不想使用ViewOverlay，因为它只支持api 18，我想知道窗口管理器，但我读到你不能在windowmanager中制作动画使用自定义。我也使用片段，

~~我有这个图像视图，一个是主图像视图和一些小图像视图。~~

mainimage imageview1 imageview2 imageview3 imageview4 imageview5

我是动画新手，我想尝试一下

现在当我点击imageview1时我想动画从imageview1到mainimage的移动效果然后将mainimage的值设置为imageview1 如果点击了其他图像也一样。

这是我的代码

griView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { ImageLibrary imgLib = adapter.get(position); mainImage = imgLib; } });

我试过这样的事情

mImagesGridView.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { // TODO Auto-generated method stub getX = event.getX(); getY = event.getY(); return false; } }); mImagesGridView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { TranslateAnimation anim = new TranslateAnimation(getX, getY, mGroupImageImageView.getX(), mGroupImageImageView.getY()); anim.setDuration(600); anim.setAnimationListener(new TranslateAnimation.AnimationListener() { @Override public void onAnimationStart(Animation animation) { } @Override public void onAnimationRepeat(Animation animation) { } @Override public void onAnimationEnd(Animation animation) { // set image in mainImage view final float growTo = 0.7f; final long duration = 200; ScaleAnimation grow = new ScaleAnimation(1, growTo, 1, growTo, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f); grow.setDuration(duration / 2); ScaleAnimation shrink = new ScaleAnimation(growTo, 1, growTo, 1, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f); shrink.setDuration(duration / 2); shrink.setStartOffset(duration / 2); AnimationSet growAndShrink = new AnimationSet(true); growAndShrink.setInterpolator(new LinearInterpolator()); growAndShrink.addAnimation(grow); growAndShrink.addAnimation(shrink); mGroupImageImageView.startAnimation(growAndShrink); } }); view.findViewById(R.id.Image_imageview).startAnimation(anim); } });

Answer 1

你可以试试这个

TranslateAnimation anim = new TranslateAnimation(0, 0, amountToMoveRight, amountToMoveDown);
anim.setDuration(1000);

anim.setAnimationListener(new TranslateAnimation.AnimationListener() {

@Override
public void onAnimationStart(Animation animation) { }

@Override
public void onAnimationRepeat(Animation animation) { }

@Override
public void onAnimationEnd(Animation animation) 
{
   // set image in mainImage view 
}
});

view.startAnimation(anim);

Answer 2

我猜这个来自Google的示例符合您的要求

获取源代码并进行一些修改。

在运行时根据用户触摸创建新的图像视图，并将Image Image动画到另一个ImageVIew
