OverlayImageView

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.

Usage:

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.

Customization

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.
