Loader View for Android

What It Is

Provide both TextView and ImageView the ability to show shimmer (animation loader) before any text or image is shown. Useful when waiting for data to be loaded from the network. Example below

Features / Usage

1. Loader View for TextView defined in layout XML

   <com.elyeproj.loaderviewlibrary.LoaderTextView
   
   android:layout_width="match_parent"
   
   android:layout_height="wrap_content" />

2. Loader View for ImageView defined in layout XML

   <com.elyeproj.loaderviewlibrary.LoaderImageView
   
   android:layout_width="100dp"
   
   android:layout_height="100dp" />

3. Define the % width of the TextView that shows the loading animation with width_weight

   <com.elyeproj.loaderviewlibrary.LoaderTextView
   
   android:layout_width="match_parent"
   
   android:layout_height="wrap_content"
   
   app:width_weight="0.4" />

4. Define the % height of the TextView that shows the loading animation with height_weight

   <com.elyeproj.loaderviewlibrary.LoaderTextView
   
   android:layout_width="match_parent"
   
   android:layout_height="wrap_content"
   
   app:height_weight="0.8" />

5. Define use gradient of the TextView or ImageView that shows the gradient with use_gradient

   <com.elyeproj.loaderviewlibrary.LoaderTextView
   
   android:layout_width="match_parent"
   
   android:layout_height="wrap_content"
   
   app:use_gradient="true" />

6. Setting the Text Style as BOLD would darken the loading shimmer

7. Other feature of TextView and ImageView is still applicable.

   myLoaderTextView.resetLoader();
    myLoaderImageView.resetLoader();
