我试图在我的项目中执行TwoWayView,方法是按照该链接中提供的示例项目。我已经实现了一切,我的代码工作没有任何错误,但实际列表没有得到充气。经过调试,我发现适配器设置正确,getItemCount
方法也返回正数,但其他两个重写的方法onCreateViewHolder
和onBindViewHolder
没有被调用。我不知道为什么它不工作。请参阅下面的部分代码,任何帮助表示赞赏。谢谢。RecyclerView.Adapter的onCreateViewHolder和onBindViewHolder方法没有被调用
MyAdapter.java类
public class MyAdapter extends RecyclerView.Adapter <MyViewHolder> {
private MySimpleCursorAdapter mCursor;
//some other private fields here
public MyAdapter(Context context, Cursor c, int resourceId, ViewType viewType, String containerId) {
mCursor = new MySimpleCursorAdapter(a1,a2,a3,a4,a5,a6); //Passed necessary arguments
....
}
@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
Log.w("onCreateViewHolder", "--------->executed"); //Line not executed
final View view = mCursor.newView(mContext, mCursor.getCursor(), parent);
return new MyViewHolder(view);
}
@Override
public void onBindViewHolder(MyViewHolder holder, int position) {
Log.w("onBindViewHolder", "--------->executed"); //Line not executed
mCursor.bindView(holder.itemView, mContext, mCursor.getCursor());
}
@Override
public int getItemCount() {
Log.w("count", Integer.toString(mCursor.getCount())); //This is executed
return mCursor.getCount();
}
private class MySimpleCursorAdapter extends SimpleCursorAdapter {
public MySimpleCursorAdapter(Context context, int layout, Cursor c, String[] from, int[] to, int flags) {
super(context, layout, c, from, to, flags);
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
View view = mLayoutInflater.inflate(mLayoutToInflate, null);
....
return view;
}
@Override
public void bindView(final View view, Context context, Cursor cursor) {
//Implemented this method for inflating all subviews inside each item of the list
}
}
}
注:我有过类似的问题消失,但提供的答案,因为我的RecyclerView
是不是里面ScrollView
,也是getItemCount
是有不相关的我的问题返回正数。
