#### 安装教程

1.在项目根目录下的build.gradle文件中，

 ```gradle
allprojects {
    repositories {
        maven {
            url 'https://s01.oss.sonatype.org/content/repositories/releases/'
        }
    }
}
 ```

2.在entry模块的build.gradle文件中，

 ```gradle
 dependencies {
    implementation('com.gitee.chinasoft_ohos:Ohos_Multibackstack: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


XML中添加控件:

```xml
    <StackLayout
            ohos:id="$+id:show_stack"
            ohos:height="match_content"
            ohos:width="match_parent"
            ohos:weight="10"/>
```

```java
       searchFraction = new SearchFraction(this);
               favoritesFraction = new FavoritesFraction(this);
               proFileFraction = new ProFileFraction(this);
               ((FractionAbility) getAbility()).getFractionManager()
                       .startFractionScheduler()
                       .add(ResourceTable.Id_show_stack, searchFraction)
                       .add(ResourceTable.Id_show_stack, favoritesFraction)
                       .add(ResourceTable.Id_show_stack, proFileFraction)
                       .hide(favoritesFraction)
                       .hide(proFileFraction)
                       .show(searchFraction)
                       .submit();
               addAction(searchFraction, -1);
```

```java
      @Override
          protected void onBackPressed() {
              if (list.size() == 1) {
                  stopAbility(intent);
                  System.exit(0);
                  return;
              }
              Action action = (Action) list.get(list.size() - 2);
              int item = action.getItem();
              initComponent();
              if (action.getFraction() instanceof SearchFraction) {
                  searchFraction.setItem(item);
                  setSearchAnimator(search, search_img, ResourceTable.Media_search_true, search_text);
                  selectInt = 0;
              } else if (action.getFraction() instanceof ProFileFraction) {
                  proFileFraction.setItem(item);
                  setSearchAnimator(profile, profile_img, ResourceTable.Media_mine_true, profile_text);
                  selectInt = 2;
              } else if (action.getFraction() instanceof FavoritesFraction) {
                  favoritesFraction.setItem(item);
                  setSearchAnimator(favorites, favorites_img, ResourceTable.Media_heart_true, favorites_text);
                  selectInt = 1;
              }
              ((FractionAbility) getAbility()).getFractionManager()
                      .startFractionScheduler()
                      .hide(searchFraction)
                      .hide(favoritesFraction)
                      .hide(proFileFraction)
                      .show(action.getFraction())
                      .submit();
              if (list.size() != 0) {
                  list.remove(list.size() - 1);
              }
          }
```
