我如何在ScrollView中嵌套两个RecyclerView并禁用scrollview的滚动

Question

I have a activity like this:

<?xml version="1.0" encoding="utf-8"?>
<com.hyqfx.recyclerviewtest.LockScrollView
  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">

    <android.support.v7.widget.RecyclerView
      android:id="@+id/recycler_view_1"
      android:layout_width="match_parent"
      android:layout_height="400dp"/>

    <android.support.v7.widget.RecyclerView
      android:id="@+id/recycler_view_2"
      android:layout_width="match_parent"
      android:layout_height="400dp"/>
  </LinearLayout>

</com.hyqfx.recyclerviewtest.LockScrollView>

and the LockScrollView like this:

public class LockScrollView extends ScrollView {
  public LockScrollView(Context context) {
    super(context);
  }

  public LockScrollView(Context context, AttributeSet attrs) {
    super(context, attrs);
  }

  public LockScrollView(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
  }

  @Override public boolean onTouchEvent(MotionEvent ev) {
    return false;
  }
}

In this situation, the scrollview will no scroll first, but when the recyclerview scroll to the bottom, the parent scrollview work again.

But I want the scrollview do not work ever.

Someone can help me? thanks very much!

Answer 1

use NestedScrollView instead of ScrollView

You can use this way either : Add this line to your recyclerView xml view :

android:nestedScrollingEnabled="false"

try it , recyclerview will be smoothly scrolled with flexible height

hope this helped .
