Android - translating an image larger than the screen size causes blur

I am trying to make a game with several "screens." If the user moves to the edge of the screen, an animation should appear that shifts the current screen and switches to a new screen.

I wanted to do this with TranslateAnimation. First, I compute a bitmap that contains the first and second screens, and then I want to play it in the transitionView, while I hide the levelView that originally contained the first screen. When the transition is complete, I want to hide the "transitionView" again and display the new screen in the "levelView".

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/viewGroup" 
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <view
            class="at.test.game.ScreenTransitionTest2$LevelView"
            android:id="@+id/levelView" 
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>

    <view
            class="at.test.game.ScreenTransitionTest2$TransitionView"
            android:id="@+id/transitionView" 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:visibility="gone"/> 
</RelativeLayout>

ImageView, , . View, (0, 0). , onCreate:

((RelativeLayout)findViewById(R.id.viewGroup)).setClipChildren(false);

:

this.transitionView.setBitmap(calculateBitmap(screen1, screen2));
TranslateAnimation a = new TranslateAnimation(
    Animation.ABSOLUTE, startx, Animation.ABSOLUTE, endx,
    Animation.ABSOLUTE, starty, Animation.ABSOLUTE, endy);
a.setDuration(3000);
a.setFillAfter(true); 
this.transitionView.setAnimation(a);
a.start();

: 480x800 / ( 1000x880, (-40, -40), endcoordinates (-520, -40)) ( , ) (. )

? ? 'wrap_content' view, . ?
