문제

Currently this is my scrollbar.xml file:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >

    <gradient
        android:angle="45"
        android:centerColor="@color/blue"
        android:endColor="@color/blue"
        android:startColor="@color/blue" />

    <corners android:radius="8dp" />

</shape>

And this is my ScrollView:

<ScrollView
    android:id="@+id/scrollView1"
    android:scrollbarThumbVertical="@drawable/scrollbar"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentRight="true"
    android:layout_below="@+id/btnBack" >

This is the scrollbar it gives me. It's good, except it's too thick and obvious. It may not look thick in this screenshot, but it really is.

enter image description here

Am I able to set a ScrollView property to adjust the width/thickness of the scrollbar? Or can I put a property in my gradient?

해결책

add the following property to your layout

android:scrollbarSize="50dip"

다른 팁

see the android:scrollbarSize="" attribute of ScrollView.

<ScrollView
    android:id="@+id/scrollView1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentRight="true"
    android:layout_below="@+id/btnBack"
    android:scrollbarSize="4dp"
    android:scrollbarThumbVertical="@drawable/scrollbar" >

For making very easy and using many times, same type of scrollbar in list view, use as a style and color in style.xml and color.xml in values folder.

i.e. in Android Studio :

Project_Name/app/main/res/values

and the code in

style.xml

 <resources>    
   <style name="mScrollBar">
     <item name="android:scrollbarSize">1dp</item>
     <item name="android:scrollbarThumbVertical">@color/base_color</item>
   </style>
 </resources>

in color.xml

 <?xml version="1.0" encoding="utf-8"?>
 <resources>
     <color name="Salmon">#FA8072</color>
 </resources>
