两回收视图之间的拖放 [英] Drag and Drop Between Two Recycle View

问题描述

我已经创建了2个Horizo​​ntal recycleView。哪个工作完美我需要在每个recycleView内的项目之间拖放的功能，以及这两个recycleView项目之间的拖放功能。我现在还在做什么 -

  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，LinearLayoutManager.HORIZONTAL，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 ，点击项目+位置）; 
} 
}）; 
（（MyRecyclerViewAdapterInCompleteTask）mAdapterInCompleteTask）.setOnItemClickListener（new MyRecyclerViewAdapterInCompleteTask.MyClickListener（）{
 @Override 
 public void onItemClick（int position，View v）{
 Log.i（LOG_TAG ，点击项目+位置）; 
} 
}）; 
} 
 
 private ArrayList< DataObject> getDataSet（）{
 ArrayList results = new ArrayList< DataObject>（）; （int index = 0; index< 20; index ++）{
 DataObject obj = new DataObject（Some Primary Text+ index，
Secondary+ index）; 
 
 results.add（index，obj）; 
} 
返回结果; 
}

解决方案

如果您仍然对一个简单的解决方案感兴趣在GitHub上查看我的代码。它显示如何拖放两个 RecyclerView s。

I have created 2 Horizontal recycleView. Which is working perfectly. I need the functionality of drag and drop between item inside each recycleView as well as drag and drop between those two recycleView's item. What I did still now -

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, LinearLayoutManager.HORIZONTAL, 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, View v) {
            Log.i(LOG_TAG, " 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;
}

Customised this library and got the things that I want. Link - https://github.com/woxblom/DragListView
