android – 两个回收视图之间的拖放

我创建了2个Horizo​​ntal recycleView.这是完美的.我需要在每个recycleView中的项目之间拖放功能,以及在这两个recycleView项目之间拖放.我现在还做了什么 –

private RecyclerView mRecyclerViewCompletedTask;
private RecyclerView.Adapter mAdapterCompletedTask;
private RecyclerView.LayoutManager mLayoutManagerCompletedTask;
private static String LOG_TAG = "RecyclerViewActivity";
private RecyclerView mRecyclerViewInCompleteTask;
private RecyclerView.Adapter mAdapterInCompleteTask;
private RecyclerView.LayoutManager mLayoutManagerInCompleteTask;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main2);

    mRecyclerViewCompletedTask = (RecyclerView) findViewById(R.id.my_recycler_view_completed_task);
    mRecyclerViewCompletedTask.setHasFixedSize(true);
    mLayoutManagerCompletedTask = new linearlayoutmanager(this);
    mRecyclerViewCompletedTask.setLayoutManager(mLayoutManagerCompletedTask);
    mAdapterCompletedTask = new MyRecyclerViewAdapterCompletedTask(getDataSet());
    mRecyclerViewCompletedTask.setAdapter(mAdapterCompletedTask);
    linearlayoutmanager layoutManager1 = new linearlayoutmanager(this,linearlayoutmanager.HORIZONTAL,false);
    mRecyclerViewCompletedTask.setLayoutManager(layoutManager1);

    mRecyclerViewInCompleteTask = (RecyclerView) findViewById(R.id.my_recycler_view_incomplete_task);
    mRecyclerViewInCompleteTask.setHasFixedSize(true);
    mLayoutManagerInCompleteTask = new linearlayoutmanager(this);
    mRecyclerViewInCompleteTask.setLayoutManager(mLayoutManagerInCompleteTask);
    mAdapterInCompleteTask = new MyRecyclerViewAdapterInCompleteTask(getDataSet());
    mRecyclerViewInCompleteTask.setAdapter(mAdapterInCompleteTask);
    linearlayoutmanager layoutManager2 = new linearlayoutmanager(this,false);
    mRecyclerViewInCompleteTask.setLayoutManager(layoutManager2);
}

@Override
protected void onResume() {
    super.onResume();
    ((MyRecyclerViewAdapterCompletedTask) mAdapterCompletedTask).setonItemClickListener(new MyRecyclerViewAdapterCompletedTask.MyClickListener() {
        @Override
        public void onItemClick(int position,View v) {
            Log.i(LOG_TAG," Clicked on Item " + position);
        }
    });
    ((MyRecyclerViewAdapterInCompleteTask) mAdapterInCompleteTask).setonItemClickListener(new MyRecyclerViewAdapterInCompleteTask.MyClickListener() {
        @Override
        public void onItemClick(int position," Clicked on Item " + position);
        }
    });
}

private ArrayList<DataObject> getDataSet() {
    ArrayList results = new ArrayList<DataObject>();
    for (int index = 0; index < 20; index++) {
        DataObject obj = new DataObject("Some Primary Text " + index,"Secondary " + index);
        results.add(index,obj);
    }
    return results;
}

自定义这个库,得到了我想要的东西.链接 – https://github.com/woxblom/DragListView
