如何将BaseAdapter设置为RecyclerView？
如何将BaseAdapter设置为RecyclerView？
提问于 2018-06-04 18:22:13
每当我需要实现自定义的ListView或GridView时。我总是使用这样一个BaseAdapter类：
public class CustomFlowerGridViewAdapter extends BaseAdapter {
private HashMap<String, String> mFlowerFeed = new HashMap<>();
private Context mContext;
static LayoutInflater mFlowerInflater = null;
CustomFlowerGridViewAdapter(Context context, ArrayList<HashMap<String, String>> data) {
super();
this.mContext = context;
MainActivity.flowerArrayFeedList = data;
mFlowerInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount() {
return MainActivity.flowerArrayFeedList.size();
}
@Override
public Object getItem(int i) {
return MainActivity.flowerArrayFeedList.size();
}
@Override
public long getItemId(int i) {
return i;
}
@Override
public View getView(int i, View view, ViewGroup viewGroup) {
final ViewHolder holder;
if(view == null){
view = mFlowerInflater.inflate(R.layout.flower_grid_row, viewGroup, false);
holder = new ViewHolder();
holder.name = (TextView) view.findViewById(R.id.mainGridName);
view.setTag(holder);
mFlowerFeed = MainActivity.flowerArrayFeedList.get(i);
mFlowerImage = MainActivity.flowerArrayImageList.get(i);
}
else{
holder = (ViewHolder) view.getTag();
mFlowerFeed = MainActivity.flowerArrayFeedList.get(i);
mFlowerImage = MainActivity.flowerArrayImageList.get(i);
}
holder.name.setText(mFlowerFeed.get("name"));
return view;
}
private class ViewHolder {
TextView name
}
}但是，现在我正在尝试实现一个Horizontal ListView。在做了一些研究之后，我发现实现水平ListView的“正确”方法是使用RecyclerView。这就是我的MainActivity
CustomFlowerGridViewAdapter customFlowerGridViewAdapter = new CustomFlowerGridViewAdapter(MainActivity.this, flowerArrayFeedList);
flowersGrid.setAdapter(customFlowerGridViewAdapter);问题是当我尝试设置适配器时。

我找到了一个很简单的解决方案。不需要处理RecyclerViews
然后，在包装器内，指定角度为90。
com.github.rongi.rotate_layout.layout.RotateLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/mainFlowersGridL"
android:layout_below="@+id/mainFlowersHeading"
android:layout_width="match_parent"
android:layout_height="170dp"
app:angle="90"> <!-- Specify rotate angle here -->
<GridView
android:id="@+id/mainFlowersGrid"
android:layout_below="@+id/mainFlowersHeading"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</GridView>
</com.github.rongi.rotate_layout.layout.RotateLayout>然后，在自定义元素xml文件中。将布局指定为-90。
