DropDownMenu
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.
##Feature
- use Adapter to add the SubDropDownMenu. Override the
getView()method to supply the wantted view. - use Generic to make all kinds of model(pojo,javabean...) can be used.
- use FilterCheckedView which implements
Checkable, so you can use selector to respond to all user action. - use FilterUrl to save the current choosen data, only override
toString()you will get the url.
##ScreenShot 
Usage
the 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:
//set the Adapter. dropDownView.setMenuAdapter(new DropMenuAdapter(this, titleList));
the DropMenuAdapter:
@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:
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, "", "");
}
}
}
);
//?????
singleListView.setList(list, -1);
//?????
}
