Question

我在Adapter RecyclerView中单击按钮时出现问题。点击按钮总是更多点击以获得响应。但我想点击一下，然后得到回应..

这是我的按钮。

<Button
        android:id="@+id/btn_action"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:drawableTop="@drawable/ic_add_white_24dp"
        android:theme="@style/Button.Blue" />

这是我的适配器

public class NewsAdapter extends RecyclerView.Adapter<NewsAdapter.ViewHolder> implements View.OnClickListener {

    .............

    private OnNewsItemClickListener OnNewsItemClickListener;

    public void setOnNewsItemClickListener(OnNewsItemClickListener onNewsItemClickListener) {
        this.OnNewsItemClickListener = onNewsItemClickListener;
    }

    public interface OnNewsItemClickListener {
        public void onActionClick(View v, int position);

    }

    public NewsAdapter(Activity activity, ArrayList<HashMap<String, String>> News,
                       ArrayList<HashMap<String, String[]>> newsArticleImages) {
        this.activity = activity;
        dataNews = News;


    }


    @Override
    public void onClick(View v) {

        final int viewId = v.getId();
        if (viewId == R.id.btn_action) {
            if (OnNewsItemClickListener != null) {
                OnNewsItemClickListener.onActionClick(v, (Integer) v.getTag());
            }
        }
    }

    public class ViewHolder extends RecyclerView.ViewHolder {

        @Bind(R.id.btn_action)
        Button btn_action;

        public ViewHolder(View vi) {
            super(vi);
            ButterKnife.bind(this, vi);

        }

    }

    @Override
    public NewsAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
                                                     int viewType) {
        View v = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.pin_item_news_recyclerview, parent, false);
        ViewHolder holder = new ViewHolder(v);
        holder.btn_action.setOnClickListener(this);
        return holder;
    }

    public void onBindViewHolder(final ViewHolder holder, int position) {



    }
.............
}

这个我的Activity调用ClickListener

public class BusinessActivity extends AppCompatActivity implements OnRefreshListener, NewsAdapter.OnNewsItemClickListener {


        @Bind(R.id.grid_view) RecyclerView list;

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

            adapter = new NewsAdapter(BusinessActivity.this, NewsList,
                    NewsArticleImagesList);
            adapter.setOnNewsItemClickListener(this);
            list.setHasFixedSize(true);

            list.setAdapter(adapter);

        }



    @Override
    public void onActionClick(View v, int position) {

        HashMap<String, String> news = new HashMap<String, String>();
        news= adapter.dataNews.get(position);
        String btn_des = news.get(Variabel.KEY_BTN_DES);
        if(btn_des.equals("Add News")) {
            Bundle b = new Bundle();
            Intent i;
            i = new Intent(BusinessActivity.this, AddNewsActivity.class);
            b.putString(Variabel.KEY_BUSINESS_NAME, business_name);
            b.putString(Variabel.KEY_INFO_FULL, info_full);
            b.putString(Variabel.KEY_SUB_INFO_FULL, sub_info_full);
            b.putString(Variabel.KEY_ID_BUSINESS, _idBusiness);
            i.putExtras(b);
            startActivity(i);
        }
    }
    }

那么如何解决呢？

如果它响应点击事件，我猜它正常工作。这可能只是需要时间。尝试单击一次并等待一段时间。如果它正在响应那么它的工作正常。这可能是性能问题。发布您的代码，以便我们可以更好地了解实际发生的情况。

尝试使用以下适配器，并根据需要进行任何更改。您的“ViewHolder”类应该实现View.OnClickListener而不是适配器本身。

单击适配器RecylerView中的按钮？
