Android 在回收器列表视图中设置所选项目的背景色

我想更改“回收者”列表视图中某个视图的背景颜色，并在同一列表视图中单击另一个项目时恢复为默认颜色

我的回收器视图模板如下

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/list_view_click_background"
    xmlns:custom="http://schemas.android.com/apk/res-auto">


    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:weightSum="2"
        android:padding="10dp">

        <com.kahoindia.dev.customclasses.KaHOTextView
            android:id="@+id/txtHomework"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:paddingLeft="10dp"
            style="@style/kaho_content_label_textview_style"
            custom:CustomTextViewFont="@string/kaho_segoeui_regular_font"
            android:layout_weight="1.5"
            />

        <com.kahoindia.dev.customclasses.KaHOTextView
            android:id="@+id/txtDate"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:gravity="right"
            android:paddingRight="10dp"
            custom:CustomTextViewFont="@string/kaho_segoeui_regular_font"
            style="@style/kaho_content_description_textview_style"
            android:layout_weight="0.5"/>

    </LinearLayout>

</LinearLayout>

和KahoiRecycleServiceItemClickListener接口

public interface KaHOIRecyclerViewItemClickListener {
    void onClick(View view, int position);

    void onLongClick(View view, int position);
}

但这突出了多重立场。请帮助我

尝试使用

视图

而不是

mRecyclerView.getChildAt（i）

否其不起作用您是否尝试过为recycler视图项目添加单击侦听器（当您将项目绑定到recycler视图时）？是的，我尝试过。。同样不起作用的请发布RecyclerTouchListener的代码，以及KahoiRecyclerviceItemClickListener类，所以我可以帮忙。

 public class RecyclerTouchListener implements RecyclerView.OnItemTouchListener {

        private GestureDetector gestureDetector;
        private KaHOIRecyclerViewItemClickListener clickListener;

        public RecyclerTouchListener(Context context, final RecyclerView recyclerView, final KaHOIRecyclerViewItemClickListener clickListener) {
            this.clickListener = clickListener;
            gestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
                @Override
                public boolean onSingleTapUp(MotionEvent e) {
                    return true;
                }

                @Override
                public void onLongPress(MotionEvent e) {
                    View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
                    if (child != null && clickListener != null) {
                        clickListener.onLongClick(child, recyclerView.getChildLayoutPosition(child));
                    }
                }
            });
        }

        @Override
        public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {

            View child = rv.findChildViewUnder(e.getX(), e.getY());
            if (child != null && clickListener != null && gestureDetector.onTouchEvent(e)) {
                clickListener.onClick(child, rv.getChildLayoutPosition(child));
            }
            return false;
        }

        @Override
        public void onTouchEvent(RecyclerView rv, MotionEvent e) {
        }

        @Override
        public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

        }
    }

public interface KaHOIRecyclerViewItemClickListener {
    void onClick(View view, int position);

    void onLongClick(View view, int position);
}
