This library provides an Imageview which can paint a layer on top of the image. This feature could be used for text protection or to apply a tint to an image.
Import the project by adding this line to your build.gradle
compile 'eu.giovannidefrancesco:overlayimageview:1.0'
And then you can drop this tag in your layout:
<eu.giovannidefrancesco.overlayimageview.OverlayImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@drawable/my_beautiful_picture" />
Replace my_beatiful_picture with your own image and you are ready to go.
By default the app puts a black overlay (alpha=0.5) on the image. However, you can always change this by adding the following tags to your xml:
<eu.giovannidefrancesco...
xmlns:app="http://schemas.android.com/apk/res-auto"
app:tintColor="@color/my_beatiful_color"/>
Or set it programmatically:
//red tint
int color = Color.argb(80, 200, 0,0);
//mOverlayImageView has been already set with findViewById...
mOverlayImageView.setTintColor(color);
Of course, any color can be used.
