draglistview's Issues

Nullpointer on ItemAdapter

Trying to run your DEMO gives me this error:

01-24 15:38:34.486 25175-25175/se.lamnea.exhibition.admin E/AndroidRuntime: FATAL EXCEPTION: main Process: se.lamnea.exhibition.admin, PID: 25175 java.lang.NullPointerException: Attempt to invoke virtual method 'int com.woxthebox.draglistview.DragItemAdapter.getPositionForItemId(long)' on a null object reference at com.woxthebox.draglistview.DragItemRecyclerView.onDragStarted(DragItemRecyclerView.java:258) at com.woxthebox.draglistview.DragListView$2.onDragStarted(DragListView.java:146) at com.woxthebox.draglistview.DragItemAdapter$ViewHolder$1.onLongClick(DragItemAdapter.java:121) at android.view.View.performLongClick(View.java:5236) at android.view.View$CheckForLongPress.run(View.java:20900) at android.os.Handler.handleCallback(Handler.java:739) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:145) at android.app.ActivityThread.main(ActivityThread.java:5951) at java.lang.reflect.Method.invoke(Native Method) at java.lang.reflect.Method.invoke(Method.java:372) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1400) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1195)

I am using your ListFragment class and haven't changed anything about what items are being populated or not.

It seems like the item adapter (here I also use the DEMO ItemAdapter) is null for some reason? But this line is in ListFragment, setting the adapter:
mDragListView.setAdapter(listAdapter, true);

What am I doing wrong? Thank you for the help!

Cannot click on item without dragging

Hi,

I have an EditText inside the drag item. I want to edit that EditText when I click on it and drag the item with a long-click but it's currently seems impossible to me. It starts to drag when I click it (without having to "long-click").

I tried to force onItemLongClicked (of the viewholder) to return false or true but neither works. I also tried setting the grabhandle to the container layout of the whole item (the current grabhandle is the EditText) but then I can't always drag (maybe because the child views almost fill the container), but even if I can drag the item, it's "click to drag" not "long-click to drag".

Am I missing something here? How can I accomplish it?

Thank you.

How to drag rows programmatically

Hi,

Thank you very much for this awesome bunch of code. It really helped me out.
Now I need to programmatically drag a specific row to a new row location.
Instead of dragging by finger I need to do that programmatically.
I checked on This link and This, But I couldn't get, that much of a clue.
For my requirement do I need to create my own DragEvent? (But how can I specify from :to movement of the row) or is it possible to use the existing code?

Regards,

Change the color of the dragView at item drop

@OverRide
public void onItemDragEnded(int fromPosition, int toPosition) {
if (Long.valueOf(toPosition).equals((Long)(mItemArray.get(toPosition).first))) {
Toast.makeText(mDragListView.getContext(), "Correct position", Toast.LENGTH_SHORT).show();
//change the color of item
} else {
Toast.makeText(mDragListView.getContext(), "Incorrect position", Toast.LENGTH_SHORT).show();
//change the color of the item
}
}

If the row is in its correct position, the row should change its color. Also, this row should not be draggable anymore. How can I acheive this?

BUG programmatically removing items

When I remove an item from list using the following method:

public Object removeItem(int pos) {
        if (mItemList != null && mItemList.size() > pos) {
            Object item = mItemList.remove(pos);
            notifyItemRemoved(pos);
            return item;
        }
        return null;
}

The item is only HIDDEN and the row continue taking up space (the list height is not resized).

Here is my code:

@Override
public void onBindViewHolder(ViewHolder holder, int position) {
	super.onBindViewHolder(holder, position);
	String text = mItemList.get(position).second;
	holder.itemView.setTag(text);
	holder.mBtnDelete.setTag(position);
	holder.mBtnDelete.setOnClickListener(new View.OnClickListener() {
		@Override
		public void onClick(final View view) {
			removeItem(Integer.parseInt(String.valueOf(view.getTag())));
			mDragListView.requestLayout();
		}
	});
}

Can you help me?
Thanks in advance (and sorry for my probably bad english),

Can drag and scroll work in ScrollView

I just tried wrapping my DragListView in a Scrollview, but when I try to drag to the bottom, it doesn't seem to scroll.

I notice the sample code uses a SwipeRefreshLayout to achieve this affect, but I was wondering if it was possible to do with a ScrollView as well.

disable drop below top item

Hello! First of all thank you for the very useful library. As the title i want the BoardView only allows user to drop item from above of column. I managed to add a flag called "mCanNotDropBelowTopItem" and use it inside shouldChangeItemPosition method like this:
if(mCanNotDropBelowTopItem && newPos != mAdapter.getItemCount() - 1){
return false;
}
but it doesn't help. Any suggestion?
edit: "mAdapter.getItemCount() - 1" instead of 0 for "Top Item" is because i used "linearLayoutManager.setReverseLayout(true);" for RecyclerView.

Add Header to DragListView

Hello how can i add a header section to the draglistview?

Listview and different views

I was looking to create something to this effect using the vertical listview:

TextView(Section Header)
1 CardView
2 CardView
3 CardView
ImageView(Divider)
TextView(Section Header)
4 CardView
5 CardView
6 CardView
7CardView
ImageView(Divider)

The cards should be able to be dragged above and below all CardViews, TextViews, and ImageViews.

The only way I can see of doing it is by manually changing the viewholder in onbind by setting the visibility of elements etc which is really nasty.

Is there any other way of achieving this?

wrap_content height does not seem to work. ListView always takes full height.

Hi, me again, enjoying this resource very much. However, I'm having trouble showing a DragListView as a smaller portion of my fragment. In the screenshot, you can see that the DragListView is occupying all the vertical space it can instead of wrapping to the height of only its 3 items. It would be great if the view could dynamically size to be just tall enough for its items. If an item were added/removed, it could then resize, like a regular ListView. Or am I missing something?
My code is below the screenshot.

My layout. Notice I have a commented-out ListView which I used to confirm that a normal ListView wraps its height with the exact same attributes.

Code where I set up the DragListView:

private void setupListView(){
        mDragListView = (DragListView) rootView.findViewById(R.id.drag_list_view);
        mDragListView.setDragListListener(new DragListView.DragListListener() {
            @Override
            public void onItemDragStarted(int position) {
                Toast.makeText(getActivity(), "Start - position: " + position, Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onItemDragEnded(int fromPosition, int toPosition) {
                if (fromPosition != toPosition) {
                    Toast.makeText(getActivity(), "End - position: " + toPosition, Toast.LENGTH_SHORT).show();
                }
            }
        });

        mDragListView.setLayoutManager(new LinearLayoutManager(getActivity()));
        listAdapter = new Adapter_SemesterDragItemAdapter(semesterList, R.layout.semester_list_item, R.id.color_tab, false);
        mDragListView.setAdapter(listAdapter, true); // has fixedItemSize
        mDragListView.setCanDragHorizontally(false);

//        ListView tmpListView = (ListView) rootView.findViewById(R.id.drag_list_view);
//        Resources res = getResources();
//        ArrayAdapter<Semester> tmpAdapter = new ArrayAdapter<Semester>(getActivity(), R.layout.my_spinner_item, semesterList);
//        tmpListView.setAdapter(tmpAdapter);
    }

What input is acceptable for the grabHandleId in the DragItemAdapter?

Hello,

Thanks for the handy library. One thing I am unsure of is what kind of input is needed for the grabHandleId. Is it an image? the id of the view to be grabbed?

In your examples, you have it as R.id.image, but when I put in 'R.id.randomBitmap' of my own, it doesn't work. I assume I'm putting the wrong sort of thing in.

yours:
ItemAdapter listAdapter = new ItemAdapter(mItemArray, R.layout.list_item, R.id.image, false);
Mine:

Possible stack overflow (not tested, but quite apparent)

In DragItemAdapter, you've got:

            mGrabView.setOnTouchListener(new View.OnTouchListener() {
                @Override
                public boolean onTouch(View view, MotionEvent event) {
                    if (mDragEnabled && event.getAction() == MotionEvent.ACTION_DOWN) {
                        mDragStartedListener.onDragStarted(itemView, mItemId);
                        return true;
                    }
                    if (!mDragEnabled && itemView == mGrabView) {
                        return onTouch(view, event);
                    }
                    return false;
                }
            });

Shouldn't onTouch(view, event) be onItemTouch(view, event)? Looks like you're going to get a stack overflow otherwise

BoardView only added last adapter for multiple column.

See the Method i am using to add multiple List in Board View.

private void addColumnList(List mItemArrayParent) {
ArrayList<Pair<Long, ProjectsList>> mItemArray = new ArrayList<>();
for (int i = 0; i < mItemArrayParent.size(); i++) {
for (int loop=0;loop<mItemArrayParent.get(i).getProjectList().size();loop++) {
ProjectsList projectsList = mItemArrayParent.get(i).getProjectList().get(loop);
mItemArray.add(new Pair<>(Long.parseLong(projectsList.getProjectID()), projectsList));
}
int addItems = mItemArray.size();
Log.e("Size","/"+addItems);
AdapterDepartment listAdapter = new AdapterDepartment(mItemArray, R.layout.column_item, R.id.item_layout, true);
View header = View.inflate(getActivity(), R.layout.column_header, null);
((TextView) header.findViewById(R.id.header)).setText(mItemArrayParent.get(i).getDeptName());
((TextView) header.findViewById(R.id.header_count)).setText(Integer.toString(addItems));
mBoardView.addColumnList(listAdapter, header, false);
mItemArray.clear();
}
}

Facing Space in the creation of ListView

Every time I try to make a list, even when the adapter is of this type:
ArrayList<Pair<Long, String>> but actually I want to use ArrayList<Pair<Integer, DeliveryResponseViewModel>>

When DeliveryResponseViewModel is a Object I made.

The List is created with multiple spaces.
If I have 3 elements, it will create 9 spaces, with this logic: Right View, empty, empty, Second Right View, empty, empty, Third Right View, empty, empty
I think I being missing some kind of library maybe about the ProGuard rules, or maybe I missing something bigger.

How to update item data upon being dragged

Hi,

I would like to update data on the item being dragged.

For example (attached picture), I'm dragging Item 2, so I would like to change Item 2 data on the fly, on every canDragItemAtPosition event, that is, Item 1 should show dynamic data along the way being moved.

Is there a way to get access to that view being dragged?

Any idea would be appreciated.

Anyway to set `DragItemRecyclerView mRecyclerView` gravity to TOP?

Hi, it's me again from issue #40

I'm not sure if this problem is related to your library or not, so please kindly help if you have time.

The problem occurs here is when an EditText is focused with myEditText.requestFocus(); or being pressed, the keyboard appears and covers that EditText (The EditTexts at the top of the screen which are still visible when the keyboard popups work just fine). I solved this problem once but the structure was different (Your DragListView was a nested child inside a RecyclerView). I solved it by setting the android:layout_gravity="top" for the RecyclerView parent. But now I don't need the nested anymore so your DragListView is the parent now and I use ViewType to create the different ViewHolder. The android:layout_gravity="top" won't work anymore.

I started thinking that maybe setting DragItemRecyclerView mRecyclerView gravity to TOP may solve the problem.

I tried adding a new method into your DragListView class:

public void setLayoutGravityToTop(){
        ViewGroup.LayoutParams layoutParams = mRecyclerView.getLayoutParams(); 
        LinearLayout.LayoutParams castLayoutParams = (LinearLayout.LayoutParams) layoutParams; 
        castLayoutParams.gravity = Gravity.TOP; 
        mRecyclerView.setLayoutParams(castLayoutParams);
        Log.d("check","Done setting!");
    }

But it doesn't seems to work. The Log was never shown.

Thank you.

Incosistent drag behaviour

Hi Wox,

I'm probably missing something here.

• After implementing the library I noticed I'm getting some problems with the visibility of the items.
  • The list was not visible, because all items together with the "floating" view have visibility set to invisible: click
  • I had to set the item visiblity to VISIBLE manually in onBindViewHolder(): click
• After setting the visibility manually i get some inconsistent behaviour: click
  • The "floating" view is show properly, but the list item is not hidden
  • Items move inadequately up and down the list
  • Items are reordered even by the slightest y-movement
• I initially thought this might be caused by the fact that the list is placed in a ScrollView. It's not - I tested it outside of the ScrollView, same bahaviour.
• My code
  • Setting up the RecyclerVIew
  • Adapter
  • Item layout
• Device is Nexus 5 with 6.0.1; SDK Tools v25.2.4
