有人使用RecyclerView找到了一种方法来设置一个onClickListener的项目在RecyclerView? 我想设置一个监听器为每个项目的布局,但这似乎有点太麻烦了 我确信有一种方法让RecyclerView监听onClick事件,但我不能完全弄清楚。

这就是我最后需要的东西,以防有人发现它有用:
public static class ViewHolder extends RecyclerView.ViewHolder {
public ViewHolder(View item) {
super(item);
item.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Log.d("RecyclerView", "onClick:" + getAdapterPosition());
}
});
}
}

您可以将clickListener传递给适配器。
在活动中:
private View.OnClickListener mItemClick = new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = null;
int position = list.getChildPosition(v);
switch (position) {
case 0:
intent = new Intent(MainActivity.this, LeakCanaryActivity.class);
break;
case 1:
intent = new Intent(MainActivity.this, ButterKnifeFragmentActivity.class);
break;
}
if (intent != null) {
MainActivity.this.startActivity(intent);
}
}
};
然后将它传递给适配器:
MainAdapter mainAdapter = new MainAdapter(this, mItemClick);
在适配器的onCreateViewHolder中:
@Override
public MainAdapter.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int position) {
View itemView = activity.getLayoutInflater().inflate(R.layout.main_adapter_item, viewGroup, false);
ViewHolder holder = new ViewHolder(itemView);
itemView.setOnClickListener(mItemClick);
return holder;
}
太简单和有效了。
而不是实现接口视图。OnClickListener内的视图持有人或创建和接口和实现接口在您的活动- 我使用这段代码简单的OnClickListener实现。
public static class SimpleStringRecyclerViewAdapter
extends RecyclerView.Adapter<SimpleStringRecyclerViewAdapter.ViewHolder> {
// Your initializations goes here...
private List<String> mValues;
public static class ViewHolder extends RecyclerView.ViewHolder {
//create a variable mView
public final View mView;
/*All your row widgets goes here
public final ImageView mImageView;
public final TextView mTextView;*/
public ViewHolder(View view) {
super(view);
//Initialize it here
mView = view;
/* your row widgets initializations goes here
mImageView = (ImageView) view.findViewById(R.id.avatar);
mTextView = (TextView) view.findViewById(android.R.id.text1);*/
}
}
public String getValueAt(int position) {
return mValues.get(position);
}
public SimpleStringRecyclerViewAdapter(Context context, List<String> items) {
mBackground = mTypedValue.resourceId;
mValues = items;
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.list_item, parent, false);
view.setBackgroundResource(mBackground);
return new ViewHolder(view);
}
@Override
public void onBindViewHolder(final ViewHolder holder, int position) {
holder.mBoundString = mValues.get(position);
holder.mTextView.setText(mValues.get(position));
//Here it is simply write onItemClick listener here
holder.mView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Context context = v.getContext();
Intent intent = new Intent(context, ExampleActivity.class);
context.startActivity(intent);
}
});
}
@Override
public int getItemCount() {
return mValues.size();
}
}
这个作品。
public class ServiceListAdapter extends RecyclerView.Adapter<ServiceListAdapter.ViewHolder> {
private final Context mContext;
private List<ServiceListModel> categoryList;
private View.OnClickListener onClickListener;
public ServiceListAdapter(Context mContext, List<ServiceListModel> categoryList, View.OnClickListener onClickListener) {
this.categoryList = categoryList;
this.mContext = mContext;
this.onClickListener = onClickListener;
}
@Override
public ViewHolder onCreateViewHolder(final ViewGroup parent, final int viewType) {
final LayoutInflater inflater = LayoutInflater.from(parent.getContext());
final RowServiceListBinding binding = DataBindingUtil.inflate(inflater, R.layout.row_service_list, parent, false);
return new ViewHolder(binding.getRoot(), binding);
}
@Override
public void onBindViewHolder(final ViewHolder holder, final int position) {
holder.binding.rlService.setOnClickListener(onClickListener);
holder.binding.rlService.setTag(position);
}
@Override
public int getItemCount() {
return categoryList.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
private final RowServiceListBinding binding;
public ViewHolder(final View view, final RowServiceListBinding binding) {
super(view);
this.binding = binding;
}
@UiThread
public void bind(final ServiceListModel mAddressModel) {
//this.binding.setAddress(mAddressModel);
}
}
}
在活动/片段中使用
ServiceListAdapter adapter = new ServiceListAdapter(context, serviceList, new View.OnClickListener() {
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.rlService:
int pos = (int) v.getTag();
serviceList.remove(position);
break;
}
}
});
下面是我的代码片段:
v.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
int newPosition = MainActivity.mRecyclerView.getChildAdapterPosition(v);
Intent cardViewIntent = new Intent(c, MainActivityCards.class);
cardViewIntent.putExtra("Position", newPosition);
c.startActivity(cardViewIntent);
}
});
v是onCreateViewHolder的视图 c为背景信息
这对我来说很管用。将OnClickListener附加到onBindView。我真的不知道这是否会影响性能,但它似乎用很少的代码就能很好地工作。
public void onBindViewHolder(ViewHolder holder, final int position) {
holder.view.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Toast.makeText(context, "Recycle Click" + position, Toast.LENGTH_SHORT).show();
}
});
}
