## DropDownMenu
[![Android Arsenal](https://img.shields.io/badge/Android%20Arsenal-DropDownMenu-green.svg?style=true)](https://android-arsenal.com/details/1/3803)


This is a DropDownMenu with the advantage of all the dropDownMenus by others before,
I have written it for several times, Now the code is most clearly.

[中文文档](README-cn.md)

##Feature
1. use Adapter to add the SubDropDownMenu. Override the `getView()` method to supply the wantted view.
2. use Generic to make all kinds of model(pojo,javabean...) can be used.
3. use FilterCheckedView which implements `Checkable`, so you can use selector to respond to all user action.
4. use FilterUrl to save the current choosen data, only override `toString()` you will get the url.

## Usage 
the xml: 
```xml
<com.baiiu.filter.DropDownMenu
    android:id="@+id/filterDropDownView"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:id="@id/mFilterContentView" //mFilterContentView must be add into the view.the view can be a RecyclerView or others.
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center_vertical"
        android:textSize="22sp" />
</com.baiiu.filter.DropDownMenu> 
```

the JavaCode:
```java
//set the Adapter.
dropDownView.setMenuAdapter(new DropMenuAdapter(this, titleList));
```

the DropMenuAdapter:
```java
@Override
public int getMenuCount() {
    return titles.length;
}

@Override
public String getMenuTitle(int position) {
    return titles[position];
}

@Override
public int getBottomMargin(int position) {
    return 0;
}

@Override
public View getView(int position, FrameLayout parentContainer) {
    ...
    return createSingleListView();
}
```

add a SingleListView:
```java
private View createSingleListView() {

    SingleListView<String> singleListView = new SingleListView<String>(mContext)
            .adapter(new SimpleTextAdapter<String>(null, mContext) {
                @Override
                public String provideText(String string) {
                    return string;
                }
            })
            .onItemClick(new OnFilterItemClickListener<String>() {
                @Override
                public void onItemClick(String item) {
                    FilterUrl.instance().singleListPosition = item;

                    FilterUrl.instance().position = 0;
                    FilterUrl.instance().positionTitle = item;

                    if (onFilterDoneListener != null) {
                        onFilterDoneListener.onFilterDone(0, "", "");
                    }
                }
            });
            
    //初始化数据
    singleListView.setList(list, -1);//默认不选中
}
```
