我的工作RecyclerView，並嘗試使用上點擊監聽recyclcerview的每個項目使用接口RecyclerVIew onItemClickListener不工作
這裏是我的Activity類：
public class LegacyHomeActivity extends ActivityBaseDrawer {
private List<LegacyVideo> legacyVideoList = null;
private List<Video> videoList = new ArrayList<>();
private RecyclerView mRecyclerView;
private LegacyModeHomeAdapter adapter;
@Override
public void onNetworkStateChanged(boolean connected) {
}
@Override
protected void onCreate(Bundle savedInstanceState) {
isLegacyMode = true;
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_legacy_home);
if (getSupportActionBar() != null) {
setTitle(getString(R.string.footy_legacy_home));
}
ImageView legacy_live_score_imageView = (ImageView) findViewById(R.id.legacy_live_score_imageView);
legacy_live_score_imageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
startActivity(new Intent(LegacyHomeActivity.this, LegacyLiveScoreActivity.class));
}
});
ImageView legacy_highlight_imageView = (ImageView) findViewById(R.id.legacy_highlight_imageView);
legacy_highlight_imageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
startActivity(new Intent(LegacyHomeActivity.this, LegacyHighlightsActivity.class));
}
});
ImageView legacy_news_imageView = (ImageView) findViewById(R.id.legacy_news_imageView);
legacy_news_imageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
startActivity(new Intent(LegacyHomeActivity.this, LegacyNewsActivity.class));
}
});
mRecyclerView = (RecyclerView) findViewById(R.id.legacy_mood_recyclerview);
final LinearLayoutManager layoutManager = new LinearLayoutManager(getApplicationContext(), LinearLayoutManager.VERTICAL, false);
mRecyclerView.setLayoutManager(layoutManager);
adapter = new LegacyModeHomeAdapter(getApplicationContext(), itemClickListener);
mRecyclerView.setAdapter(adapter);
mRecyclerView.setHasFixedSize(true);
swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipeRefreshLayout);
swipeRefreshLayout.setColorSchemeResources(R.color.ThemeColor,
R.color.ThemeColor, R.color.ThemeColor);
swipeRefreshLayout
.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
getLegacyVideoList();
}
});
circularProgressView = (CircularProgressView) findViewById(R.id.circularProgressView);
showLoadingProgress();
getLegacyVideoList();
}
LegacyVideoClickListener itemClickListener = new LegacyVideoClickListener() {
@Override
public void onItemClickListener(int position) {
Video video = videoList.get(position);
VideoPlayerUtil.initVideoPLayer(video, LegacyHomeActivity.this);
}
};
private void getLegacyVideoList() {
FootyLightAPI api = new FootyLightAPI(getApplicationContext(), mResponseListener);
api.getLegacyHomeVideoList();
}
private final FootyLightAPI.ResponseListener mResponseListener = new FootyLightAPI.ResponseListener() {
@Override
public void getResponse(int apiId, final String response) {
switch (apiId) {
case R.integer.ApiLegacyVideoList:
Log.e("Legacy ............", "Response:................" + response);
try {
final ObjectMapper mapper = new ObjectMapper();
legacyVideoList = mapper.readValue(response, new TypeReference<List<LegacyVideo>>() {
});
if (legacyVideoList != null && legacyVideoList.size() > 0) {
videoList.clear();
for (LegacyVideo video : legacyVideoList) {
Log.e("Legacy video", "" + video.getTitle());
Video videoItem = new Video();
if (video.getItemType().equalsIgnoreCase("video")) {
videoItem.setTitle(video.getTitle());
videoItem.setLink(video.getLink());
videoItem.setThumb(video.getThumb());
videoItem.setContentType(video.getContentType());
videoItem.setContentUrl(video.getContentUrl());
videoItem.setDmcaLabel(video.getDmcaLabel());
videoItem.setDmcaContent(video.getDmcaContent());
videoItem.setDmcaDisclaimer(video.getDmcaDisclaimer());
videoItem.setDisplayType(video.getDisplayType());
videoList.add(videoItem);
}
}
}
Log.e("VideoList", "........." + videoList.size());
runOnUiThread(new Runnable() {
@Override
public void run() {
showVideoAdapter();
hideLoadingProgress();
}
});
} catch (Exception e) {
}
break;
default:
break;
}
}
@Override
public void getError(int apiId, int errorCode) {
}
@Override
public void getResponse(String trackingStr, int apiId, String response) {
}
@Override
public void getError(String trackingStr, int apiId, int errorCode) {
}
};
public void showVideoAdapter() {
if (adapter != null) {
adapter.setVideos(videoList);
}
}
}
這裏是我的適配器類
public class LegacyModeHomeAdapter extends RecyclerView.Adapter<LegacyModeHomeAdapter.ItemViewHolder> {
private List<Video> videoList;
private Context mContext;
private LegacyVideoClickListener onVideosRVItemClickListener;
private LayoutInflater getLayoutInflater() {
return LayoutInflater.from(mContext);
}
public LegacyModeHomeAdapter(Context mContext, LegacyVideoClickListener onVideosRVItemClickListener) {
this.mContext = mContext;
this.onVideosRVItemClickListener = onVideosRVItemClickListener;
}
public void setVideos(List<Video> videosList) {
this.videoList = videosList;
notifyDataSetChanged();
}
@Override
public ItemViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = getLayoutInflater().inflate(R.layout.layout_legacy_mode_home_video_item, parent, false);
return new ItemViewHolder(view);
}
@Override
public void onBindViewHolder(ItemViewHolder holder, final int position) {
Video video = videoList.get(position);
Picasso.with(mContext).load(video.getThumb()).into(holder.categoryImage);
holder.categoryName.setText(video.getTitle());
holder.title_image_btn.setText(video.getDisplayType());
holder.VideosItemClickListener(position, onVideosRVItemClickListener);
}
@Override
public int getItemCount() {
if (videoList != null) {
return videoList.size();
}
return 0;
}
public class ItemViewHolder extends RecyclerView.ViewHolder {
private TextView categoryName;
private ImageView categoryImage;
private Button title_image_btn;
public ItemViewHolder(View itemView) {
super(itemView);
categoryName = (TextView) itemView.findViewById(R.id.categoryName);
categoryImage = (ImageView) itemView.findViewById(R.id.categoryImage);
title_image_btn = (Button) itemView.findViewById(R.id.title_image_btn);
}
public void VideosItemClickListener(final int position, final LegacyVideoClickListener videosRVItemClickListener) {
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
videosRVItemClickListener.onItemClickListener(position);
}
});
}
}
}
最後我使用這個接口監聽器：
public interface LegacyVideoClickListener {
public void onItemClickListener(int position);
}
此過程做工精細所有我的應用程序的其他部分，但不工作的這種情況。我不知道問題在哪裏。請幫幫我 。
這不是一個好方法。因爲onBindViewHolder將在回滾器視圖滾動時被調用。所以每當列表滾動時，即使有一點點，它都會爲當前可見的所有項目設置onClickListener，這是無效的。 – CodeCameo
不，它沒有被調用。方法綁定被稱爲永遠recyclerView滾動 –
是啊...這就是我剛纔所說的。當你再次滾動一下時，它會再次爲同一個itemView調用'setOnClickListener'，不是嗎？ – CodeCameo
