A custom RecyclerView for Android TV end.
1.First you can add gradle dependency with command :
dependencies {
......
compile 'com.henryblue.library:tvrecyclerview:0.9.7'
}
To add gradle dependency you need to open build.gradle (in your app folder,not in a project folder) then copy and add the dependencies there in the dependencies block;
2.Add TvRecyclerView in your layout
<app.com.tvrecyclerview.TvRecyclerView
android:id="@+id/tv_recycler_view"
android:layout_width="match_parent"
android:layout_height="580dp"
app:focusDrawable="@drawable/default_focus"/>
3.Set the LayoutManager and Adapter
mTvRecyclerView = (TvRecyclerView) findViewById(R.id.tv_recycler_view);
GridLayoutManager manager = new GridLayoutManager(NormalFocusActivity.this, 3);
manager.setOrientation(LinearLayoutManager.HORIZONTAL);
mTvRecyclerView.setLayoutManager(manager);
int itemSpace = getResources().
getDimensionPixelSize(R.dimen.recyclerView_item_space);
mTvRecyclerView.addItemDecoration(new SpaceItemDecoration(itemSpace));
NormalAdapter mAdapter = new NormalAdapter(this);
mTvRecyclerView.setAdapter(mAdapter);
mTvRecyclerView.setOnItemStateListener(new TvRecyclerView.OnItemStateListener() {
@Override
public void onItemViewClick(View view, int position) {
Log.i(TAG, "you click item position: " + position);
}
@Override
public void onItemViewFocusChanged(boolean gainFocus, View view, int position) {
}
});
mTvRecyclerView.setSelectPadding(35, 34, 35, 38);
<app.com.tvrecyclerview.TvRecyclerView
...
app:scrollMode="followScroll"
app:isAutoProcessFocus="false"
app:focusScale="1.04f"
app:focusDrawable="@drawable/default_focus"
...
/>
