# 收缩展开控件ExpandView
### How to
1.Add the JitPack repository to your build file
```
allprojects {
		repositories {
			...
			maven { url 'https://jitpack.io' }
		}
	}
```
2.Add the dependency
```
dependencies {
	        implementation 'com.gitee.eachann_lee:ExpandView:1.0.0'
	}
```

1.0.0功能重构，与业务分离，ExpandView只处理view的展开/收起,目前只支持vertical方向

```xml
 <me.eachann.widget.expand.ExpandView
        android:id="@+id/expand_view_v"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        app:ev_expanded="false"
        app:ev_parallax="0.5">

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="238dp"
            android:background="@android:color/holo_blue_bright"
            android:scaleType="fitXY" />

        <TextView
            android:layout_width="match_parent"
            android:layout_height="44dp"
            android:background="@android:color/holo_green_dark"
            android:text="@string/app_name" />
    </me.eachann.widget.expand.ExpandView>
```

代码中的示例
```java
       mTextView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mExpandViewV.toggle();
                mExpandView.toggle();
//                mHorizontalExpandView.toggle();
            }
        });
        mExpandView.setOnExpansionUpdateListener(new ExpandView.OnExpansionUpdateListener() {
            @Override
            public void onExpansionUpdate(float expansionFraction, int state) {
                Log.e("onExpansionUpdate","expansionFraction="+expansionFraction);
                mIvState.setRotation(expansionFraction*180);
                if(state==COLLAPSED||state==COLLAPSING){
                    mTvState.setText("展开");
                }else{
                    mTvState.setText("收起");
                }
            }
        });
```
