ForegroundViews

Views that support a foreground. Inspired by Chris Banes' gist and this post as well as this.

Gradle Dependency

Add this in your root build.gradle file ( not your module build.gradle file):

allprojects {
  repositories {

...
maven {
 url "https://jitpack.io" 
}
  
}
 
}

Then, add the library to your project build.gradle

dependencies {

  compile 'com.github.Commit451:ForegroundViews:latest.version.here' 
}

Usage

Usage is very similar for each of the foreground views. Within XML:

<com.commit451.foregroundviews.ForegroundLinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:foreground="?attr/selectableItemBackgroundBorderless"
android:orientation="vertical"
android:padding="16dp">
 <!-- Other views go here -->  </com.commit451.foregroundviews.ForegroundLinearLayout>

for ViewGroups and:

<com.commit451.foregroundviews.ForegroundImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/colorPrimary"
android:clickable="true"
android:foreground="?attr/selectableItemBackgroundBorderless"
android:src="@drawable/header_image_1"
android:tint="@color/colorAccent" />

for an ImageView. The key is the foreground XML attribute, which can also be set in code:

Drawable drawable = ContextCompat.getDrawable(this, R.drawable.foreground);
 ForegroundImageView foregroundImageView = (ForegroundImageView) findViewById(R.id.image);
 foregroundImageView.setForeground(drawable);

Supported Views

  • ForegroundImageView
  • ForegroundLinearLayout
  • ForegroundRelativeLayout
  • ForegroundButton
  • ForegroundTextView

There may be others that people want, so pull requests are encouraged! Please note that FrameLayout and CardView already support a foreground for all API levels.

Create Your Own Views

If you take a look at the source, you will see that the supported views all are very similar in construction. Operations are overridden in the views and then passed along to the ForegroundDelegate so that the foreground logic is easily shared and reusable on new views. Most of the time, copying the source of ForegroundLinearLayout and then modifying the name and the extended view is all you need to do.

Note

Foregrounds were added to View as of Android 6.0 (API 23). This library calls through to the 6.0+ methods whenever it is possible. If you have the ability to target 6.0+ (lol yeah right) then you have no need for a library like this. We look forward to the day when targeting 6.0+ is the standard and this library can be deprecated.

Resources

An easy, empowering Kotlin library for RecyclerView.

Android Library to implement stacked horizontal progressbar.

A simple widget that can be used to display menu's which can be animated in and out.

This is a circular widget that can be used to display a count down timer or a count up timer.

AWEX (Android Work EXecutor) is a thread pool to execute tasks that uses Promises to deliver results. Promises that can be cancelled, can be combined or even can process collections in parallel automatically.

Tesela is a code generate based library that helps you implement Model-View-Presenter pattern on Android. It let you annotate methods to make them be executed on UI thread or on a background thread. It will help you to keep a weak reference to the view, so forget about leaking your Fragment or Activity anymore while your background work finishes.
