我正在構建一個使用RecyclerView和CardView的應用程序。由於RecyclerView沒有onItemClickListener方法，我找到了一個這樣做的類實現，並且能夠將此類插入到我的項目中。將RecyclerView放在圖像前
在每張卡片中，我將一個imageView（我正在使用Glide加載圖像）和一對TextViews。當TextView低於圖像時，我可以完美地使用onItemClickListener，但我決定將圖像放在背景爲黑色透明的RelativeLayout中。
問題是，在此更改後onItemClickListener停止工作。圖像佔據整個cardView並且TextView位於其前面。通過點擊這些元素中的任何一個，該方法都不起作用。我認爲我需要將recyclerView放在活動的前面，但我不知道如何去做。我試圖使用recyclerView.bringToFront（），但它不起作用。
這是（在白色區域點擊時，點擊監聽器工作）前，把卡：
這是卡現在（當我點擊任何地方點擊監聽器不工作）：
這是我ItemClickSupport類：
public class ItemClickSupport {
private final RecyclerView mRecyclerView;
private OnItemClickListener mOnItemClickListener;
private OnItemLongClickListener mOnItemLongClickListener;
private View.OnClickListener mOnClickListener = new View.OnClickListener() {
@Override
public void onClick(View v) {
if (mOnItemClickListener != null) {
RecyclerView.ViewHolder holder = mRecyclerView.getChildViewHolder(v);
mOnItemClickListener.onItemClicked(mRecyclerView, holder.getAdapterPosition(), v);
}
}
};
private View.OnLongClickListener mOnLongClickListener = new View.OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
if (mOnItemLongClickListener != null) {
RecyclerView.ViewHolder holder = mRecyclerView.getChildViewHolder(v);
return mOnItemLongClickListener.onItemLongClicked(mRecyclerView, holder.getAdapterPosition(), v);
}
return false;
}
};
private RecyclerView.OnChildAttachStateChangeListener mAttachListener
= new RecyclerView.OnChildAttachStateChangeListener() {
@Override
public void onChildViewAttachedToWindow(View view) {
if (mOnItemClickListener != null) {
view.setOnClickListener(mOnClickListener);
}
if (mOnItemLongClickListener != null) {
view.setOnLongClickListener(mOnLongClickListener);
}
}
@Override
public void onChildViewDetachedFromWindow(View view) {
}
};
private ItemClickSupport(RecyclerView recyclerView) {
mRecyclerView = recyclerView;
mRecyclerView.setTag(R.id.item_click_support, this);
mRecyclerView.addOnChildAttachStateChangeListener(mAttachListener);
}
public static ItemClickSupport addTo(RecyclerView view) {
ItemClickSupport support = (ItemClickSupport) view.getTag(R.id.item_click_support);
if (support == null) {
support = new ItemClickSupport(view);
}
return support;
}
public static ItemClickSupport removeFrom(RecyclerView view) {
ItemClickSupport support = (ItemClickSupport) view.getTag(R.id.item_click_support);
if (support != null) {
support.detach(view);
}
return support;
}
public ItemClickSupport setOnItemClickListener(OnItemClickListener listener) {
mOnItemClickListener = listener;
return this;
}
public ItemClickSupport setOnItemLongClickListener(OnItemLongClickListener listener) {
mOnItemLongClickListener = listener;
return this;
}
private void detach(RecyclerView view) {
view.removeOnChildAttachStateChangeListener(mAttachListener);
view.setTag(R.id.item_click_support, null);
}
public interface OnItemClickListener {
void onItemClicked(RecyclerView recyclerView, int position, View v);
}
public interface OnItemLongClickListener {
boolean onItemLongClicked(RecyclerView recyclerView, int position, View v);
}
}
這是我從我的活動稱之爲：
ItemClickSupport.addTo(recyclerView).setOnItemClickListener(new ItemClickSupport.OnItemClickListener() {
@Override
public void onItemClicked(RecyclerView recyclerView, int position, View v) {
Intent intent = new Intent(getBaseContext(), MovieDetails.class);
intent.putExtra("movie_name", movies.get(position).getTitle());
intent.putExtra("movie_rating", movies.get(position).getVoteAverage().toString());
intent.putExtra("movie_description", movies.get(position).getOverview());
intent.putExtra("movie_cover", movies.get(position).getPosterPath());
intent.putExtra("movie_date", movies.get(position).getReleaseDate());
intent.putExtra("movie_language", movies.get(position).getOriginalLanguage());
intent.putExtra("movie_backdrop", movies.get(position).getBackdropPath());
//intent.putExtra("album_name", albumList.get(position).getName());
//intent.putExtra("album_thumbnail", Integer.toString(albumList.get(position).getThumbnail()));
//intent.putExtra("number_songs", Integer.toString(albumList.get(position).getNumOfSongs()));
startActivity(intent);
}
});
這是我的適配器：
public class MoviesAdapter extends RecyclerView.Adapter<MoviesAdapter.MyViewHolder> {
private Context mContext;
private List<MovieItem> movieList;
public class MyViewHolder extends RecyclerView.ViewHolder {
public TextView title, count;
public ImageView thumbnail, overflow, star1, star2, star3, star4, star5;
public MyViewHolder(View view) {
super(view);
title = (TextView) view.findViewById(R.id.title);
count = (TextView) view.findViewById(R.id.count);
thumbnail = (ImageView) view.findViewById(R.id.thumbnail);
star1 = (ImageView) view.findViewById(R.id.rating_image1);
star2 = (ImageView) view.findViewById(R.id.rating_image2);
star3 = (ImageView) view.findViewById(R.id.rating_image3);
star4 = (ImageView) view.findViewById(R.id.rating_image4);
star5 = (ImageView) view.findViewById(R.id.rating_image5);
//overflow = (ImageView) view.findViewById(R.id.overflow);
}
}
public MoviesAdapter(Context mContext, List<MovieItem> movieList) {
this.mContext = mContext;
this.movieList = movieList;
}
@Override
public MoviesAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.album_card, parent, false);
return new MyViewHolder(itemView);
}
@Override
public void onBindViewHolder(final MoviesAdapter.MyViewHolder holder, int position) {
MovieItem movie = movieList.get(position);
holder.title.setText(movie.getTitle());
holder.count.setText("R: " + movie.getVoteAverage().toString() + "/10");
Glide.with(mContext).load("https://image.tmdb.org/t/p/w500" + movie.getPosterPath()).into(holder.thumbnail);
}
@Override
public int getItemCount() {
return movieList.size();
}
}
嘗試onItemClickListener，它會在你點擊cardview不論TextView的或imageview的我希望它會幫助你可以分享你的適配器代碼工作。 。 – Sahil

感謝您的答覆！我只是將我的適配器添加到代碼中。 –
