BoardView

BoardView is a custom view that allows you to be able to re-order items in a list as well as in a board. You can drag and drop items between columns as well as drag and drop columns.

Example

Download library with Jitpack.io

Add this to your build.gradle file for your app.

	allprojects {
		repositories {
			...
			maven { url 'https://jitpack.io' }
		}
	}

Add this to your dependencies in build.gradle for your project.

	dependencies {
	        compile 'com.github.jakebonk:BoardView:1.0.3'
	}

Usage

BoardView utilizes a BoardAdapter, SimpleBoardAdapter is an example of how to extend BoardAdapter.

	BoardView boardView = (BoardView)findViewById(R.id.boardview);
	ArrayList<SimpleBoardAdapter.SimpleColumn> data = new ArrayList<>();
        ArrayList<String> list = new ArrayList<String>();
        list.add("Item 1");
        list.add("Item 2");
        list.add("Item 3");
        list.add("Item 4");
        data.add(new SimpleBoardAdapter.SimpleColumn("Column 1",list));
        data.add(new SimpleBoardAdapter.SimpleColumn("Column 2",list));
        data.add(new SimpleBoardAdapter.SimpleColumn("Column 3",list));
        data.add(new SimpleBoardAdapter.SimpleColumn("Column 4",list));
        data.add(new SimpleBoardAdapter.SimpleColumn("Column 5",list));
        SimpleBoardAdapter boardAdapter = new SimpleBoardAdapter(this,data);
        boardView.setAdapter(boardAdapter);

There are two types of drag listeners, the first is for columns

	 boardView.setOnDragColumnListener(new BoardView.DragColumnStartCallback() {
            @Override
            public void startDrag(View view, int startColumnPos) {

            }

            @Override
            public void changedPosition(View view, int startColumnPos, int newColumnPos) {

            }

            @Override
            public void endDrag(View view, int startColumnPos, int endColumnPos) {

            }
        });

Similarly we can get the drag listener for items

	 boardView.setOnDragItemListener(new BoardView.DragItemStartCallback() {
            @Override
            public void startDrag(View view, int startItemPos, int startColumnPos) {

            }

            @Override
            public void changedPosition(View view, int startItemPos, int startColumnPos, int newItemPos, int newColumnPos) {

            }

            @Override
            public void endDrag(View view, int startItemPos, int startColumnPos, int endItemPos, int endColumnPos) {

            }
        });

Creating your own BoardAdapter

Creating a custom BoardAdapter is pretty similar to that of a BaseAdapter, the main focus being to create some type of object that help you create your custom views for both headers and items.

Things to fix

There is a scaling issue when the column is beginning dragging or has ended dragging. I know this is an issue but I don't know of a good way to solve this at the moment. I eventually will fix it but for now I'm putting it on the back burners.
