Keep Coding

I need to set my wide image (1800x1201px) as the background of my activity so I can place the app logo and sign in/sign up buttons above.
I tried using a FrameLayout with an ImageView. The animation is working, however the image is not filling the entire FrameLayout height.
Activity
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/splash_base_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="br.com.myapp.app.activities.SplashActivity">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/splash_bg_image"
android:src="#drawable/splash_background"
android:contentDescription=""
android:scaleType="matrix"
android:adjustViewBounds="false"
android:cropToPadding="false" />
</FrameLayout>
Activity Class
public class SplashActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
animateBackground();
}
private void animateBackground() {
final ImageView splashImage = (ImageView) findViewById(R.id.splash_bg_image);
splashImage.startAnimation(outToLeftAnimation());
}
private Animation outToLeftAnimation() {
Animation outtoLeft = new TranslateAnimation(
Animation.RELATIVE_TO_PARENT, 0.0f,
Animation.RELATIVE_TO_PARENT, -1.0f,
Animation.RELATIVE_TO_PARENT, 0.0f,
Animation.RELATIVE_TO_PARENT, 0.0f);
outtoLeft.setDuration(20000L);
return outtoLeft;
}
}
Here's how it is currently previewed on Android Studio:
I tried setting layout_height both with match_parent and wrap_content, but could not find the right scaleType to make it fill the screen height and create the right to left animation.
UPDATE
I created a larger image (3840x2560) for xxx-hdpi devices and now the preview shows the image the way I need, however when I run the app it has blank spaces on top and bottom.
Also I need to create kind of a "boomerang" animation so when the image has gone right to left it reverses the animation from left to right, and so on.
Updated image:

Change android:adjustViewBounds="false" to android:adjustViewBounds="true" and make its height match_parent and it's done.

Hi can you refer this example Android: proportionally stretch an ImageView to fit the whole screen width while maintaining its aspect ratio
