在动态视图中翻译动画效果不佳

Question

In this project, I want to move TextView's clone from top TextView place to bottom TextView place when button is click.

I got a problem in using Translate Animation. I want to move a view to exact position(Like in Zapya).

In Zapya, when user select item and choose "send", the gridview item's clone move to user icon. So, I use Translate Animation to move view. And I created a view dynamically to show item's clone.

Using Translate Animation works with view that is initially created in xml but not with view that is dynamically created.

The code is here

    top = (TextView) findViewById(R.id.textviewtop);
    bottom = (TextView) findViewById(R.id.textviewbottom);
    button = (Button) findViewById(R.id.button);


    button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            int []from = new int[2];
            int []to = new int[2];

              from[0] = (int) top.getX();
            from[1] = (int) top.getY();
             to[0] = (int) bottom.getX();
            to[1] = (int) bottom.getY();
            ViewGroup vg = (ViewGroup) top.getParent();

            view = new TextView(getApplicationContext());
            view.setWidth(top.getWidth());
            view.setHeight(top.getHeight());
            view.setX(from[0]);
            view.setY(from[1]);
            view.setText(top.getText());
            view.setVisibility(View.VISIBLE);
            view.setTextColor(Color.BLACK);
            view.setId(0x23454657);
            vg.addView(view);


            TranslateAnimation anim = new TranslateAnimation( 0, 0 , from[1], to[1] );
            anim.setDuration(1000);
            anim.setFillAfter( true );
            view.startAnimation(anim);



        }
    });

and xml file

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/rl"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/textviewtop"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_alignParentTop="true"
        android:text="@string/hello_world" />


    <Button 
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:text="Move"/>

    <TextView
        android:id="@+id/textviewbottom"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_alignParentBottom="true"
        android:text="@string/hello_world" />
</RelativeLayout>

"view" show only starting and ending time. But not in between. How can I solve that. Please tell if there's any other way. I will thanks a ton.

增加持续时间，可能是一个问题

anim.setDuration(4000);
