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

   xml复制

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

2. Loader View for ImageView defined in layout XML

   xml复制

   <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

   xml复制

   <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

   xml复制

   <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

   xml复制

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

6. Define rectangle round radius using corner. The default corner is 0.

   xml复制

   <com.elyeproj.loaderviewlibrary.LoaderTextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:corners="16" />

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

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

9. Use a custom shimmer color (note: if set, point 7 will not apply, your color will be used even if the Text Style is BOLD)

   xml复制

   <com.elyeproj.loaderviewlibrary.LoaderTextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:custom_color="@android:color/holo_green_dark" />

10. Reset and show shimmer (animation loader) again by calling the below API

    java复制

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