我知道這個問題已被問了很多次,但沒有解決我的問題。我正在嘗試在RecyclerView中使用CardView,但目前還沒有運氣。 這裏是我的代碼:如何修復錯誤膨脹類Android.support.v7.widget.CardView
<?xml version="1.0" encoding="utf-8"?>
<Android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.Android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
card_view:cardCornerRadius="4dp"
card_view:cardBackgroundColor="#AA66CC"
card_view:cardElevation="10dp"
android:id="@+id/cv">
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center">
<TextView
android:layout_width="wrap_content"
android:layout_height="40dp"
android:id="@+id/list_item"
android:text="asdasd asdasd tt"
/>
</RelativeLayout>
</Android.support.v7.widget.CardView>
,這裏是我的適配器:
public class ApprovalListAdapter extends Adapter<ApprovalListAdapter.ViewHolder> {
private String[] dataSource;
private Context mContext;
public ApprovalListAdapter(String[] dataArgs, Context context){
dataSource = dataArgs;
mContext = context;
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
// create a new view
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.approval_list_row, parent, false);
ViewHolder viewHolder = new ViewHolder(view);
return viewHolder;
}
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
holder.textView.setText(dataSource[position]);
}
@Override
public int getItemCount() {
return dataSource.length;
}
public static class ViewHolder extends RecyclerView.ViewHolder{
protected TextView textView;
protected CardView cv;
public ViewHolder(View itemView) {
super(itemView);
cv = (CardView) itemView.findViewById(R.id.cv);
textView = (TextView) itemView.findViewById(R.id.list_item);
}
}
}
我還添加所需要的依賴
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:23.0.1'
compile 'com.android.support:support-v4:23.0.1'
compile 'com.android.support:recyclerview-v7:23.0.1'
compile 'com.android.support:cardview-v7:23.0.1'
compile 'com.android.support:design:23.0.1'
compile project(":volley")
}
即CardView工作完全正常時,其不RecyclerView。
沒有行爲意味着你得到什麼確切的問題? – Pavan
