我跟隨this tutorial on hiding/showing toolbar when list is scrolling。安卓與Material DesignSupport不會隱藏工具欄
如果我使用的源項目工作正常，但當我試圖創建一個示例時，它不起作用。 我有隱藏工具欄和標籤的問題。
這是我的主要活動。
<?xml version="1.0" encoding="utf-8"?>

recyclerview
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.RecyclerView
android:id="@+id/my_recycler_view"
android:scrollbars="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android" />
MyAdapter
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder>
{
int mSize;
Context mContext;
LayoutInflater mLayoutInflater;
public MyAdapter(int mSize, Context context) {
this.mSize = mSize;
this.mContext = context;
this.mLayoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = mLayoutInflater.inflate(R.layout.item_recyclerview,parent,false);
MyViewHolder myViewHolder = new MyViewHolder(v);
return myViewHolder;
}
@Override
public void onBindViewHolder(MyViewHolder holder, int position) {
holder.textView.setText("position: "+position);
}
@Override
public int getItemCount() {
return mSize;
}
public class MyViewHolder extends RecyclerView.ViewHolder{
public TextView textView;
public MyViewHolder(View itemView) {
super(itemView);
textView = (TextView) itemView.findViewById(R.id.textView);
}
}
}
，這是我的片段與回收站視圖。
public class ListFragment extends Fragment {
protected RecyclerView mRecyclerView;
public int mSize;
public int getmSize() {
return mSize;
}
public void setmSize(int mSize) {
this.mSize = mSize;
}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.recycler_view,container,false);
Log.i("mSizeOnCreateView", String.valueOf(mSize));
mRecyclerView = (RecyclerView) v.findViewById(R.id.my_recycler_view);
mRecyclerView.setHasFixedSize(true);
LinearLayoutManager llm = new LinearLayoutManager(getActivity());
llm.setOrientation(LinearLayoutManager.VERTICAL);
mRecyclerView.setLayoutManager(llm);
MyAdapter myAdapter = new MyAdapter(mSize,getActivity());
mRecyclerView.setAdapter(myAdapter);
return v;
}
}
