how to get rounded dialog theme for activity

Question

I need to create a activity which should look like as a dialog box with a rounded corners.

For this requirement I set

 android:theme=\"@android:sty         


        

Answer 1

First, create a rounded corner shape drawable like so:

dialogbg.xml:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <corners android:radius="15dp" />
</shape>

Then, go to the layout xml file for your activity, and change it's android:backgorund attribute like so

<RelativeLayout 
    android:layout_width="..." 
    android:layout_height="..." 
    android:background="@drawable/dialogbg">
    <!--views here...-->
</RelativeLayout>

Answer 2

You could make your own theme that has rounded corners. First you'll need a drawable for the Activity background:

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

    <corners android:radius="15dp" />

    <solid android:color="#565656" />

    <stroke
        android:width="3dp"
        android:color="#ffffff" />

    <padding
        android:bottom="6dp"
        android:left="6dp"
        android:right="6dp"
        android:top="3dp" />

</shape>

Next make your own theme that extends the parent Theme.Dialog:

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <style name="ThemeWithCorners" parent="android:Theme.Dialog">
        <item name="android:windowBackground">@drawable/another_test_drawable</item>
    </style>


</resources>

This will be in a file named styles.xml in the res/values folder. Use this theme in the android manifest for the Activity you want:

//...
<activity
            android:name=".ActivityName"
            android:label="@string/app_name"
            android:theme="@style/ThemeWithCorners" >
//...
