问题描述
最小SDK为21.当我在回收适配器中单击cardview时,不会发生波纹效应,而是转到下一个屏幕. recyclerview位于片段中.
Min SDK is 21. When I click on a cardview in my recycler adapter, the ripple effect doesn't happen and just goes to the next screen. The recyclerview is inside a fragment.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.v7.widget.CardView
android:id="@+id/entire_card"
android:layout_width="match_parent"
android:layout_height="265dp"
android:layout_margin="8dp"
android:foreground="?android:attr/selectableItemBackground"
app:cardUseCompatPadding="true"
app:cardCornerRadius="2dp"

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ProgressBar
android:id="@+id/progressbar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_centerHorizontal="true"
android:paddingTop="120dp"
android:visibility="visible"/>
<ImageView
android:id="@+id/pet_image"
android:layout_width="match_parent"
android:layout_height="210dp"
android:layout_alignParentTop="true"
android:scaleType="centerCrop"
android:src="@drawable/placeholder"
android:visibility="gone"
/>
<TextView
android:id="@+id/pet_description"
android:layout_width="fill_parent"
android:layout_height="55dp"
android:layout_below="@+id/pet_image"
android:padding="10dp"
android:textColor="#FFFFFF"
android:visibility="gone"
android:textSize="20sp"
android:background="@color/primaryColour"
/>
</RelativeLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
我在每个项目上都有onClick的适配器代码.
Adapter code where I have my onClick for each item.
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
public TextView petInfo;
public ImageView imgURL;
public ProgressBar progressBar;
private Context itemContext;
public ViewHolder(View v){
super(v);
imgURL = (ImageView) v.findViewById(R.id.pet_image);
petInfo = (TextView) v.findViewById(R.id.pet_description);
progressBar = (ProgressBar) v.findViewById(R.id.progressbar);
itemContext = v.getContext();
v.setOnClickListener(this);
}
@Override
public void onClick(View v){
Intent intent= new Intent(itemContext, DetailCardLayout.class);
Integer position = getAdapterPosition();
intent.putExtra("CARDVIEW_POSITION", position);
v.getContext().startActivity(intent);
}
}
推荐答案
您的卡片视图包含覆盖卡片视图表面的相对布局,因此请在相对布局中写入波纹效果.
Your card view contains relative layout which covers the card view surface, so write ripple effect in relative layout.
<android.support.v7.widget.CardView
android:id="@+id/cardView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:cardPreventCornerOverlap="false"
app:cardElevation="2dp"
app:cardUseCompatPadding="false"
app:cardCornerRadius="2dp"
android:layout_marginBottom="8dp"
android:layout_marginRight="8dp"
android:layout_marginLeft="8dp"
>
<RelativeLayout
android:id="@+id/rl_bookmark"
android:background="?attr/selectableItemBackground"
android:clickable="true"
android:layout_width="match_parent"
android:layout_height="match_parent"> ...
