Question

I need to create a component such as progressbar (as you can see in image) to act as slider. I searched Internet and find somethings like:
Custom Drawable for ProgressBar/ProgressDialog
but it was not useful for me. Please tell me how can i create this component?

Answer 1

Create your own drawable, for example progressbar.xml and set android:progressDrawable="@drawable/progressbar attrubute on your progress bar

write in progressbar.xml drawable this code:

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

    <item android:id="@android:id/background">
            <nine-patch android:src="@drawable/progressbar_bg" android:dither="true" />
    </item>

    <item android:id="@android:id/progress">
        <clip>
            <nine-patch android:src="@drawable/progressbar_body" android:dither="true" />
        </clip>
    </item>

</layer-list>

and replace @drawable/progressbar_bg and @drawable/progressbar_body with you own 9 patch png images
