我想在RecyclerVIEw中单击某项(CardVIEw)时显示Toast.此Toast必须向我显示单击的项目的位置.
当我单击CardVIEw时,我看到了波纹-这意味着单击了该卡-但不幸的是,我没有看到任何吐司.有人可以解释我为什么吗？提前致谢.

这是我的适配器：

public class MainRecyclerVIEwAdapter extends RecyclerVIEw.Adapter<MainRecyclerVIEwAdapter.MyMainVIEwHolder> {private List<information> mainInfo;MyDatabase myDatabase;public MainRecyclerVIEwAdapter(List<information> mainInfo) {    this.mainInfo = mainInfo;}public static class MyMainVIEwHolder extends RecyclerVIEw.VIEwHolder {    TextVIEw TitleTextVIEw, notesTextVIEw, dateTextVIEw, timeTextVIEw;    ImageVIEw imageVIEw;    linearLayout linearLayout;    public MyMainVIEwHolder(VIEw itemVIEw) {        super(itemVIEw);        linearLayout = (linearLayout) itemVIEw.findVIEwByID(R.ID.mainLayout);        imageVIEw = (ImageVIEw) itemVIEw.findVIEwByID(R.ID.imgIcon);        TitleTextVIEw = (TextVIEw) itemVIEw.findVIEwByID(R.ID.Title_TextVIEw);        notesTextVIEw = (TextVIEw) itemVIEw.findVIEwByID(R.ID.notes_TextVIEw);        dateTextVIEw = (TextVIEw) itemVIEw.findVIEwByID(R.ID.date_TextVIEw);        timeTextVIEw = (TextVIEw) itemVIEw.findVIEwByID(R.ID.time_TextVIEw);        itemVIEw.setonClickListener(new VIEw.OnClickListener() {            @OverrIDe            public voID onClick(VIEw v) {                Toast.makeText(v.getContext(), "position: " + Integer.toString(getAdapterposition()), Toast.LENGTH_LONG).show();            }        });    }}@OverrIDepublic MyMainVIEwHolder onCreateVIEwHolder(VIEwGroup parent, int vIEwType) {    VIEw v = LayoutInflater.from(parent.getContext()).inflate(R.layout.main_single_raw, parent, false);    MyMainVIEwHolder holder = new MyMainVIEwHolder(v);    return holder;}public voID delete(int position){    mainInfo.remove(position);    notifyItemRemoved(position);}@OverrIDepublic voID onBindVIEwHolder(final MyMainVIEwHolder holder, final int position) {    holder.imageVIEw.setimageResource(mainInfo.get(position).getICON_ID());    holder.TitleTextVIEw.setText(mainInfo.get(position).getTitle());    holder.notesTextVIEw.setText(mainInfo.get(position).getNOTES());    holder.dateTextVIEw.setText(mainInfo.get(position).getDATE());    holder.timeTextVIEw.setText(mainInfo.get(position).getTIME());}@OverrIDepublic int getItemCount() {    return mainInfo.size();}}

这是我的cardVIEw的布局文件：

解决方法:

问题解决了！这是工作代码：

public static class MyMainVIEwHolder extends RecyclerVIEw.VIEwHolder {    TextVIEw TitleTextVIEw, notesTextVIEw, dateTextVIEw, timeTextVIEw;    ImageVIEw imageVIEw;    linearLayout linearLayout;    public MyMainVIEwHolder(final VIEw itemVIEw) {        super(itemVIEw);        linearLayout = (linearLayout) itemVIEw.findVIEwByID(R.ID.mainLayout);        imageVIEw = (ImageVIEw) itemVIEw.findVIEwByID(R.ID.imgIcon);        TitleTextVIEw = (TextVIEw) itemVIEw.findVIEwByID(R.ID.Title_TextVIEw);        notesTextVIEw = (TextVIEw) itemVIEw.findVIEwByID(R.ID.notes_TextVIEw);        dateTextVIEw = (TextVIEw) itemVIEw.findVIEwByID(R.ID.date_TextVIEw);        timeTextVIEw = (TextVIEw) itemVIEw.findVIEwByID(R.ID.time_TextVIEw);        itemVIEw.setClickable(true);        itemVIEw.setFocusableIntouchMode(true);        itemVIEw.setonClickListener(new VIEw.OnClickListener() {            @OverrIDe            public voID onClick(VIEw v) {                Toast.makeText(itemVIEw.getContext(), "position: " + Integer.toString(getAdapterposition()), Toast.LENGTH_LONG).show();            }        });        linearLayout.setonClickListener(new VIEw.OnClickListener(){            @OverrIDe            public voID onClick(VIEw v) {                Toast.makeText(itemVIEw.getContext(), "position: " + Integer.toString(getAdapterposition()), Toast.LENGTH_LONG).show();            }        });    }}

所以现在,如果我单击linearLayout-在整个cardVIEw上单击-我会看到它的位置！
