Android中ViewPager+TabLayout+RecyclerView+点击事件的传递

Activity代码：

public class DownLoadedActivity extends AppCompatActivity implements DownLoadedFragment.onRecyclerItemClick {

@BindView(R.id.down_image_view)
ImageView mDownImageView;
@BindView(R.id.down_tab_layout)
TabLayout mDownTabLayout;
@BindView(R.id.down_view_pager)
ViewPager mDownViewPager;
@BindView(R.id.down_delete_iamge)
ImageView mDownDeleteIamge;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_down);
ButterKnife.bind(this);
initView();
}

private void initView() {
List<DownLoadedBaseFragment> fragments = new ArrayList<>();
fragments.add(new DownLoadedFragment());
fragments.add(new DownLoadedFragment());
DownloadedAdapter adapter = new DownloadedAdapter(getSupportFragmentManager(), fragments);
mDownViewPager.setAdapter(adapter);
mDownTabLayout.setupWithViewPager(mDownViewPager);
}

@Override
public void onRecyclerItemClick(int message) {
Toast.makeText(this, String.valueOf(message), Toast.LENGTH_SHORT).show();
}

@OnClick({R.id.down_image_view, R.id.down_delete_iamge})
public void onClick(View view) {
switch (view.getId()) {
case R.id.down_image_view:

break;
case R.id.down_delete_iamge:

break;
}
}
}

DownloadedAdapter代码：

public class DownloadedAdapter extends FragmentPagerAdapter {

private List<DownLoadedBaseFragment> mFragments;

public DownloadedAdapter(FragmentManager fm, List<DownLoadedBaseFragment> fragments) {
super(fm);
mFragments = fragments;
}

@Override
public Fragment getItem(int position) {
return mFragments.get(position);
}

@Override
public int getCount() {
int ret = 0;
if(mFragments != null){
ret = mFragments.size();
}
return ret;
}
@Override
public CharSequence getPageTitle(int position) {
return mFragments.get(position).getFragmentTitle();
}
}

DownLoadedBaseFragment 代码

public abstract class DownLoadedBaseFragment extends Fragment {
public DownLoadedBaseFragment(){

}

public abstract String getFragmentTitle();

}

DownLoadedFragment代码

public class DownLoadedFragment extends DownLoadedBaseFragment {
private onRecyclerItemClick mListener;
@BindView(R.id.down_recycler_view)
RecyclerView mDownRecyclerView;

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_downloaded, null);
ButterKnife.bind(this,view);
initView();
return view;
}

private void initView() {
DownloadedRecycylerAdapter adapter = new DownloadedRecycylerAdapter(getActivity());
adapter.setOnRecyclerItemClick(new DownloadedRecycylerAdapter.onRecyclerItemClick() {
@Override
public void onItemClick(View view, int position) {
mListener.onRecyclerItemClick(position);
Log.d("Test", "onItemClick: " + position);
}
});
mDownRecyclerView.setAdapter(adapter);
LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
mDownRecyclerView.setLayoutManager(layoutManager);
}

@Override
public String getFragmentTitle() {
return "Play";
}

public interface onRecyclerItemClick{
public void onRecyclerItemClick(int message);
}
public void onAttach(Activity activity){
super.onAttach(activity);
try {
mListener = (DownLoadedFragment.onRecyclerItemClick) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString()
+ "must implement OnGridViewSelectedListener");
}
}

}

RecyclerView适配器DownloadedRecycylerAdapter代码：

public class DownloadedRecycylerAdapter extends RecyclerView.Adapter<DownloadedRecycylerAdapter.MyViewHolder>{
private Context mContext;
private onRecyclerItemClick mOnRecyclerItemClick;
public DownloadedRecycylerAdapter(Context context) {
mContext = context;
}

@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(mContext).inflate(R.layout.down_loaded_recycler_view_item, parent, false);
ButterKnife.bind(view);
return new MyViewHolder(view);
}

@Override
public void onBindViewHolder(MyViewHolder holder, int position) {
if (mOnRecyclerItemClick != null){
if(!holder.itemView.hasOnClickListeners()){
holder.itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
int pos = holder.getPosition();
mOnRecyclerItemClick.onItemClick(v,pos);
}
});
}
}
}

@Override
public int getItemCount() {
return 12;
}

public static class MyViewHolder extends RecyclerView.ViewHolder{

public MyViewHolder(View itemView) {
super(itemView);
}
}
public interface onRecyclerItemClick {
void onItemClick(View view, int position);
}
public void setOnRecyclerItemClick(onRecyclerItemClick mOnRecyclerItemClick) {
this.mOnRecyclerItemClick = mOnRecyclerItemClick;
}
}
