### 安装教程
1.在项目根目录下的build.gradle文件中，
 ```
 allprojects {
    repositories {
        maven {
            url 'https://s01.oss.sonatype.org/content/repositories/releases/'
        }
    }
 }
```
2.在entry模块的build.gradle文件中，
 ```
 dependencies {
 implementation('com.gitee.chinasoft_ohos:loaderviewlibrary:1.0.0')
    ......
 }
```

在sdk6，DevEco Studio 2.2 Beta1下项目可直接运行
如无法运行，删除项目.gradle,.idea,build,gradle,build.gradle文件，
并依据自己的版本创建新项目，将新项目的对应文件复制到根目录下

### 使用说明

1. Loader View for TextView defined in layout XML
    ```xml
    <com.elyeproj.loaderviewlibrary.LoaderTextView
         ohos:layout_width="match_parent"
         ohos:layout_height="wrap_content" />
    ```

2. Loader View for ImageView defined in layout XML
    ```xml
    <com.elyeproj.loaderviewlibrary.LoaderImageView
         ohos:layout_width="100dp"
         ohos:layout_height="100dp" />
    ```

3. Define the % width of the TextView that shows the loading animation with `width_weight`
    ```xml
    <com.elyeproj.loaderviewlibrary.LoaderTextView
         ohos:layout_width="match_parent"
         ohos: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
    <com.elyeproj.loaderviewlibrary.LoaderTextView
         ohos:layout_width="match_parent"
         ohos: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
    <com.elyeproj.loaderviewlibrary.LoaderTextView
         ohos:layout_width="match_parent"
         ohos:layout_height="wrap_content"
         app:use_gradient="true" />
    ```

6. Define rectangle round radius using `corner`. The default corner is 0.
    ```xml
    <com.elyeproj.loaderviewlibrary.LoaderTextView
         ohos:layout_width="match_parent"
         ohos: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
    <com.elyeproj.loaderviewlibrary.LoaderTextView
         ohos:layout_width="match_parent"
         ohos:layout_height="wrap_content"
         app:custom_color="$color:holo_green_dark" />
    ```

10. Reset and show shimmer (animation loader) again by calling the below API
    ```java
    myLoaderTextView.resetLoader();
    myLoaderImageView.resetLoader();
    ```
