Question

我需要创建嵌套的recyclerView，如

RecyclerView Contains-> CardView contains-> RecyclerView。

如果我点击卡片我只能获得儿童位置，但我也需要父卡位置。如何同时处理Recyclerview和CardView的点击事件？

MainActivity.java：

public class MainActivity extends Activity {
LinearLayout linView;
private RecyclerView main_view;
RootAdapter adapter2;
private RelativeLayout mRelativeLayout;
private Context mContext;
private Activity mActivity;

int pos = 0;
int main_pos;

private static RecyclerView.Adapter adapter;
private static RecyclerView.Adapter adapterCo;
private RecyclerView.LayoutManager layoutManager;
private static ArrayList<DataModelMain> dataMain;
private static ArrayList<DataModel_CO> dataCo;
static View.OnClickListener myOnClickListener;
static View.OnClickListener onClickListener;
private static ArrayList<Integer> removedItems;
TestMain mainData = new TestMain();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    prof = (ImageView) findViewById(R.id.profile);

    main_view = (RecyclerView) findViewById(R.id.recycler_main);

    mRelativeLayout = (RelativeLayout) findViewById(R.id.partners);
    cont = (TextView) findViewById(R.id.mobile);
    iconType = (ImageView) findViewById(R.id.icon_type);
    linView = (LinearLayout) findViewById(R.id.layout_view);

    // Get the application context
    mContext = getApplicationContext();
    // Get the activity
    mActivity = MainActivity.this;

    myOnClickListener = new MyOnClickListener(this);
    onClickListener = new OnClickListener(this);

    main_view.setHasFixedSize(true);

    layoutManager = new LinearLayoutManager(
            this,
            LinearLayoutManager.VERTICAL,
            false
    ) {


    };

    main_view.setLayoutManager(layoutManager);
    main_view.setItemAnimator(new DefaultItemAnimator());
    dataMain = new ArrayList<DataModelMain>();

    getMainData();
    setMainView();
}
}

private void getMainData() {

    for (int i = 0; i < mainData.passengers.length; i++) {
        dataMain.add(new DataModelMain(
                mainData.type[i],
                mainData.passengers[i],
                mainData.p_name[i],

                mainData.p_time[i]
        ));
    }

    adapter2 = new RootAdapter(this, dataMain);
    main_view.setAdapter(adapter2);
}


private class MyOnClickListener implements View.OnClickListener {

    private final Context context;

    private MyOnClickListener(Context context) {

    private void showIcons(View v) {

如何使root / parent cardView 可点击？

为父convertlerView的 cardView 项提供ID。将它放在ViewHolderClass中，然后将一个onCLickListener分配给BindViewHolder中的cardView，如下所示：

rootViewHolder.rootCardView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
               // keep an track of the selected position of the cardView and store it in a global/local variable
            }
        });

您可以使用

跟踪所选cardView的适配器位置

rootViewHolder.getAdapterPosition()

Note: rootViewHolder is written as per your ViewHolder class

我希望这会有所帮助!!
