Animation video review

Question

I use a video review with animation (video.setAnimation (slideinRight);) Everything works fine, except that when switching only the animation of the video image is animated, not the video. When translational animation occurs, I see the box moving and masking over my video, but the video never moves with it. I am at a loss what to do now.

Answer 1

It’s a pity that I answered it quite late, but for what it costs. and if you want to use the slide animation. Try placing the video in a layout and animate the layout.

The way it was configured in my code:

AbsoluteLayout Animationlayout = (AbsoluteLayout)findViewById(R.string.frontlayout); VideoView pvv = new VideoView(getApplicationContext()); pvv.getHolder().addCallback(this); Animationlayout.addView(pvv); // load video data in pvv. 

Then, when you want to animate your video for a slide;

 Animationlayout.animate().xBy(25).setDuration(500).setInterpolator(new BounceInterpolator()); 

Please note that this is an animation system 3.1.

Not sure if classic 2.1 animation will work like that, but it should serve the same.

Material such as rotation / scaling of the layout will not work. The panorama of the layout around and the fading out seem to be just a few things that work.

I'm currently trying to put an animation in a VideoView.

If you look at the source code for Android, VideoView is basically SurfaceView , combined with MediaPlayer with basic player state machine control.

In fact, the real work of “drawing” is apparently handled by the built-in methods in mediaPlayer (aka the implementation of the game engine on your Android device).

We tested the animation on different devices and found that the behavior / implementation of the VideoView video player is not the same among different Android devices:

• Some devices correctly handle player viewing animations.
• others DO NOT, and simply display blur, a black screen or a buggy display ...

In addition, VideoView seems to be written directly to memory, so any “workaround” (for example, an opaque front view and animation settings on this view) does not seem to work.

I would be glad if other reviews were addressed to this :)

Just use TextureView :

More links to TextureView here .

I did a ZoomIn - ZoomOut animation in a TextureView .

Add the xml animation to the Res → anim folder.

zoom_in_out.xml

 <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" android:shareInterpolator="false"> <scale android:duration="1000" android:fillAfter="false" android:fromXScale="1.0" android:fromYScale="1.0" android:interpolator="@android:anim/accelerate_decelerate_interpolator" android:pivotX="50%" android:pivotY="50%" android:toXScale="1.2" android:toYScale="1.2" /> <set android:interpolator="@android:anim/decelerate_interpolator"> <scale android:duration="1000" android:fillBefore="false" android:fromXScale="1.2" android:fromYScale="1.2" android:pivotX="50%" android:pivotY="50%" android:startOffset="500" android:toXScale="1.0" android:toYScale="1.0" /> </set> </set> 

texture_layout.xml

 <?xml version="1.0" encoding="utf-8"?> <TextureView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/textureView" android:layout_margin="50dp" android:background="@android:color/darker_gray" android:layout_width="wrap_content" android:layout_height="wrap_content"> </TextureView> 

TextureViewActivity.java

 import android.graphics.SurfaceTexture; import android.media.MediaPlayer; import android.net.Uri; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.view.Surface; import android.view.TextureView; import android.view.View; import android.view.animation.Animation; import android.view.animation.AnimationUtils; import java.io.IOException; public class TextureViewActivity extends AppCompatActivity implements TextureView.SurfaceTextureListener { private TextureView textureView; private MediaPlayer mMediaPlayer; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.texture_layout); textureView = (TextureView)findViewById(R.id.textureView); textureView.setSurfaceTextureListener(this); textureView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Animation zoomAnimation = AnimationUtils.loadAnimation(TextureViewActivity.this, R.anim.zoom_in_out); textureView.startAnimation(zoomAnimation); } }); } private String getVideoPath(){ return "android.resource://" + getPackageName() + "/" + R.raw.promovideo; } @Override public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int width, int height) { Surface surface = new Surface(surfaceTexture); try { mMediaPlayer= new MediaPlayer(); mMediaPlayer.setDataSource(TextureViewActivity.this, Uri.parse(getVideoPath())); mMediaPlayer.setSurface(surface); mMediaPlayer.prepare(); mMediaPlayer.start(); mMediaPlayer.setLooping(true); } catch (IllegalArgumentException e) { e.printStackTrace(); } catch (SecurityException e) { e.printStackTrace(); } catch (IllegalStateException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } @Override public void onSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height) { } @Override public boolean onSurfaceTextureDestroyed(SurfaceTexture surface) { return false; } @Override public void onSurfaceTextureUpdated(SurfaceTexture surface) { } } 

Done
