This project can help developers implement drag and drop effects quickly.
dependencies {
...
compile 'cc.solart:dragdrop:1.1.0'
}
you can use DragDropListView as GridView, just adding two attributes.
<attr name="fixed_type" format="boolean"/>,<attr name="anim_duration" format="integer"/>
<cc.solart.dragdrop.DragDropListView
android:id="@+id/list_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false"
android:divider="@null"
android:horizontalSpacing="5dip"
android:verticalSpacing="5dip"
android:fadingEdge="none"
android:nestedScrollingEnabled="true"
android:numColumns="4"
app:fixed_type="true"/>you must layout a ImageView for drag shadow
<FrameLayout
android:id="@+id/activity_overlay"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="@+id/tile_drag_shadow_overlay"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:importantForAccessibility="no"
android:visibility="gone" />
</FrameLayout> final ImageView dragShadowOverlay =
(ImageView) findViewById(R.id.tile_drag_shadow_overlay);
mListView.setDragShadowOverlay(dragShadowOverlay);and you must extend AbsTileAdapter to implement two abstract methods that are necessary.
You must implement IDragEntity interface in order to ensure that you are properly ordered.
public class SimpleTileAdapter extends AbsTileAdapter {
private TileView.OnSelectedListener mListener;
public SimpleTileAdapter(Context context, DragDropListener dragDropListener, TileView.OnSelectedListener listener) {
super(context, dragDropListener);
...
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
...
}
@Override
protected IDragEntity getDragEntity(View view) {
...
}
} mListView.getDragDropController().addOnDragDropListener(mSimpleTileAdapter);See examples in detail.
