Android 在RecyclerView中触摸动画不会'；行不通

在我的列表xml项中，我设置了以下代码：

android:foreground="?android:attr/selectableItemBackground"
android:clickable="true"
android:focusable="true"

当我按下RecyclerView项时，它会产生一些涟漪动画。
要获取项目，请单击我使用的此类：

public class RecyclerItemClickListener implements RecyclerView.OnItemTouchListener {
private OnItemClickListener mListener;

public interface OnItemClickListener {
    public void onItemClick(View view, int position);
}

GestureDetector mGestureDetector;

public RecyclerItemClickListener(Context context, OnItemClickListener listener) {
    mListener = listener;
    mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
        @Override
        public boolean onSingleTapUp(MotionEvent e) {
            return true;
        }
    });
}

@Override
public boolean onInterceptTouchEvent(RecyclerView view, MotionEvent e) {
    View childView = view.findChildViewUnder(e.getX(), e.getY());
    if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) {
        mListener.onItemClick(childView, view.getChildAdapterPosition(childView));
    }
    return false;
}

@Override
public void onTouchEvent(RecyclerView view, MotionEvent motionEvent) {
}

@Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

}
}

并使用如下示例：

rv.addOnItemTouchListener(new RecyclerItemClickListener(getActivity(), new RecyclerItemClickListener.OnItemClickListener() {
                @Override
                public void onItemClick(View view, int position) {
                    Log.d("OnClick", "click at " + position);
                    Intent intent = new Intent(getActivity(), DetailEventActivity.class);
                    intent.putExtra("EVENT", list.get(position - 1));
                    startActivity(intent);
                }
            }));

这是我使用RecyclerView的布局：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v7.widget.RecyclerView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/rv"
        />

</RelativeLayout>

这是我的项目布局的布局：

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:clickable="true"
    android:focusable="true"
    >

我看到了很多问题和答案，我不知道为什么这个代码不起作用。也许有人能帮我

我的问题是按RecyclerView项上的动画按钮。查看项对我不起作用。

在drawable-v21文件夹中创建一个ripple drawable，id掩码用于将涟漪效果限制在您单击的行的边界内： ripple_drawable.xml

<ripple xmlns:android="http://schemas.android.com/apk/res/android"
  android:color="your rippleeffect color">
<item android:id="@android:id/mask"
     android:drawable="@android:color/white" />

你的log.d（“OnClick”，“click at”+位置）；包含点击项目的位置？你的问题是ripple动画不起作用？哇…真的没有人回答你的问题吗？你找到解决办法了吗？

android:background="@drawable/ripple_drawable"
