我想在 NestedScrollView 中放置一个 RecylerView,如下所示
活动服务菜单.xml
<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="HELLO" />
<android.support.v7.widget.RecyclerView
android:id="@+id/rv"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="8dp" />
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
ServiceMenuActivity.java
public class ServiceMenuTActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_service_menu_t);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
RecyclerView rv = (RecyclerView) findViewById(R.id.rv);
rv.setLayoutManager(new LinearLayoutManager(getApplicationContext()));
rv.setHasFixedSize(true);
rv.setAdapter(new RvAdapter());
}
private static class RvAdapter extends RecyclerView.Adapter<RvAdapter.RvHolder> {
@Override
public RvHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View serviceMenuItemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item_service_menu, parent, false);
return new RvHolder(serviceMenuItemView);
}
@Override
public void onBindViewHolder(RvHolder holder, int position) {
}
@Override
public int getItemCount() {
return 100;
}
public static class RvHolder extends RecyclerView.ViewHolder {
public RvHolder(View itemView) {
super(itemView);
}
}
}
}
我已将linearLayout 放在scrollView 和nestedScrollView 中。但是 RecyclerView 是不可见的。如果我用 FrameLayout 或任何其他布局替换 ScrollView,那么 RecyclerView 是可见的。
我想使用 nestedScrollView 并在滚动 recyclerView 时滚动整个布局。不幸的是 recyclerView 甚至不可见。
