DragLayout

RecyclerView with GridLayout that can be dragged.You may use this like the Netease ChannelManager or in some otherwise.

The DragLayout implemented with RecyclerView.

Usage:

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

dependencies {
    compile 'com.github.Syehunter:DragLayout:1.0.0'
}

There might be some error occurs when gradle build in Android Studio 2.0 with "META-INF/maven/com.belerweb/pinyin4j/pom.properties"(for I imported Pinyin4j.jar into library), just add this in your build.gradle:

android {
    ...
    packagingOptions {
        exclude 'META-INF/maven/com.belerweb/pinyin4j/pom.properties'
        exclude 'META-INF/maven/com.belerweb/pinyin4j/pom.xml'
    }
}

The layout above is DragRecyclerView, and UnsignedRecyclerView below.

Defaulst is Chinese, and the UnsignedRecyclerView is sort by Pinjin, Use this in your code if you want to change the item content only:

mDragView.datas(dragList)
            .onItemClick(new OnItemClickListener() {
                @Override
                public void onItemClick(RecyclerView.ViewHolder holder, int position) {
                    Toast.makeText(MainActivity.this,
                            "position" + position + "has been clicked", Toast.LENGTH_SHORT).show();
                }
            })
            .onLongPress(new OnLongPressListener() {
                @Override
                public void onLongPress() {
                    mQuitBtn.setVisibility(View.VISIBLE);
                }
            })
            .onItemRemoved(new OnItemRemovedListener<String>() {
                @Override
                public void onItemRemoved(int position, String removedItem) {
                    mUnsignedView.addItem(removedItem);
                }
            })
            .keepItemCount(2)
            .build();

mUnsignedView = (UnsignedRecyclerView) findViewById(R.id.unsignedView);

mUnsignedView.hanZiDatas(unsignedList)
            .onItemRemoved(new OnItemRemovedListener<String>() {
                @Override
                public void onItemRemoved(int position, String removedItem) {
                    mDragView.addItem(removedItem);
                }
            })
            .build();

Method keepItemCount() that could let you set the unmoved item counts, default is 1.

Define your adapter extends BaseDragAdapter or BaseUnsignedAdapter if you don't like this, and dragViewHolder extends BaseDragViewHolder, remember to use DragGridLayoutManager instead of GridLayoutMananger, which will adjust RecyclerView's height to wrap_content(Unfortunately the DragGridLayoutManager doesn't support RecyclerView that has set SpanSizeLookup now, I will fix it in future).
