I have a problem with xml. When I create a NestedScrollView in android studio, it doesn't scroll in the xml preview. It is so important because if I don't see preview I can't see my work. Also when I start the application, I see the latest version that should no longer be there because it was replaced by this code.

Here is my xml code:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context="mn.cdr.du.farnext.insertionActivity.InsertionActivity"
    tools:showIn="@layout/activity_insertion"
    android:paddingLeft="20dp"
    android:paddingRight="20dp"
    >

    <RelativeLayout

        android:layout_height="match_parent">

just change this code in your xml The height of the NestedScrollView Always match_parent

    <?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context="mn.cdr.du.farnext.insertionActivity.InsertionActivity"
    tools:showIn="@layout/activity_insertion"
    android:paddingLeft="20dp"
    android:paddingRight="20dp">

    <RelativeLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content">

This is not issue of height of NestedScrollView

New Android Studio has issues with scrolling ScrollView in Layout Editor. In older versions ScrollView had smooth scrolling behavior in Editor. This is a bug of Android Studio.

Solution that i usually do

  • You can see Design & Text at bottom of Layout Editor. Click on Design, there you will be able to scroll. It works perfectly all times i do.
  • If you want Text Editor scrollable, then restart your IDE (File>Invalidate Cache/ Restart>Just Restart). My Text Editor start working by this trick.
  • Just a work around : You can make your upper views invisible temporarily to see your bottom views.

The height of the NestedScrollView should be match_parent. And the child of it (RelativeLayout) should have height wrap_content.

thanks for the reply .. but in the xml preview don't scroll
layout preview is not stable. do not rely on it. did you try to clean/build project? please run the project and see the effect of changes on app.

ScrollViews usually don't scroll in the XML preview. You can only see them on the device. That's why its always better to have an android phone connected to your system for live testing.

That way, you can easily correct any errors
