Android 收听RecyclerView上的点击

我一直在努力在RecyclerView上实现一个点击监听器。我已经看到了几种方法，并且更愿意处理活动中的ImageView点击，因为我需要将意图传递给另一个活动，并在主线程之外完成一些工作。以下是我迄今为止实施的内容：

在自定义RecyclerView适配器中注册单击

public class BasemapAdapter extends RecyclerView.Adapter<BasemapViewHolder> {

// Context to construct view
private Context mContext;
// Copy of all BasemapItems
private ArrayList<BasemapItem> items;

private int rowLayout;

public BasemapAdapter(ArrayList<BasemapItem> portalItems, int rowLayout, Context context){
    this.mContext = context;
    this.items = portalItems;
    this.rowLayout = rowLayout;
}

@Override
public BasemapViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType){
    View view = LayoutInflater.from(viewGroup.getContext()).inflate(rowLayout, viewGroup, false);

    return new BasemapViewHolder(view);

}

/**
 * Fill the view with data from our adapter
 *
 * @param viewHolder
 * @param position
 */
@Override
public void onBindViewHolder(BasemapViewHolder viewHolder, final int position){
    // get the element from your dataset at this position
    // replace the contents of the view with the element
    viewHolder.basemapImage.setImageBitmap(items.get((position)).basemapImage);
    viewHolder.basemapName.setText(items.get((position)).item.getTitle());

    viewHolder.setBasemapClickListener(new BasemapViewHolder.BasemapClickListener() {
        @Override
        public void onBasemapItemClicked(View view, int position) {
            Log.d("TAG", "clicked at " + position);
        }
    });

}

@Override
public int getItemCount(){
    return items == null ? 0 : items.size();
}
}

在活动中创建适配器的实例

mBasemapAdapter = new BasemapAdapter( mBasemapList , R.layout.row_basemap, this);

mRecyclerView.setAdapter(mBasemapAdapter);

如果要处理ImageView，只需单击鼠标即可，应按如下操作：

@InjectView(R.id.basemapName) TextView basemapName;
@InjectView(R.id.basemapImage) ImageView basemapImage;

private BasemapClickListener clickListener;

public BasemapViewHolder(View itemView) {
    super(itemView);

    ButterKnife.inject(this, itemView);

    // set listener to whole item view
    //itemView.setOnClickListener(this); // comment out this line
    basemapImage.setOnClickListener(this); // <---- add this line
}

---

我通过在TextView上设置onClickListener解决了这个问题，因为它覆盖了ImageView：

BasemapAdapter

    @Override
public void onBindViewHolder(BasemapViewHolder viewHolder, final int position){
    final BasemapItem item = items.get(position);
    // get the element from your dataset at this position
    // replace the contents of the view with the element
    viewHolder.image.setImageBitmap(items.get(position).getImage());
    viewHolder.title.setText(items.get(position).getItem().getTitle());

    viewHolder.title.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if(item != null){
                clickListener.onImageClick(items.indexOf(item));
            }
        }
    });

    viewHolder.itemView.setTag(item);
}

然后我可以从活动内部调用onBaseMapClickListener

        mBasemapAdapter.setOnBaseMapClickListener(new BasemapClickListener() {

        @Override
        public void onImageClick(int position) {
            Toast.makeText(getApplicationContext(), "tapped" + position, Toast.LENGTH_LONG).show();
        }
    });

我一直在整项视图或ImageView上设置侦听器。两者都不适用于我。@jdone我将检查我的编辑并查看。如果无效，请告诉我是否调用了void onClick（视图v）。当前setOnBasemapClickListener（）位于BasemapViewHolder上，它是onBindViewHolder（）中的一个参数，因此无法进行更改。我之前在BasemapAdapter上将它设置为一个内部类，并尝试在视图的onBindViewHolder（）中执行，但代码从未到达onClick（）@jdONeill，这很奇怪。尝试使用findviewbyid而不是imageview的注入，看看它是否有效。是的，在提出问题之前尝试过，没有运气。我有一个简单的应用程序，现在真的很困惑。

    @Override
public void onBindViewHolder(BasemapViewHolder viewHolder, final int position){
    final BasemapItem item = items.get(position);
    // get the element from your dataset at this position
    // replace the contents of the view with the element
    viewHolder.image.setImageBitmap(items.get(position).getImage());
    viewHolder.title.setText(items.get(position).getItem().getTitle());

    viewHolder.title.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if(item != null){
                clickListener.onImageClick(items.indexOf(item));
            }
        }
    });

    viewHolder.itemView.setTag(item);
}

        mBasemapAdapter.setOnBaseMapClickListener(new BasemapClickListener() {

        @Override
        public void onImageClick(int position) {
            Toast.makeText(getApplicationContext(), "tapped" + position, Toast.LENGTH_LONG).show();
        }
    });
