How to make custom dialog with rounded corners in android

Create a xml in drawable , say dialog_bg.xml

<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android">    <solid        android:color="@color/white"/>    <corners        android:radius="30dp" />    <padding        android:left="10dp"        android:top="10dp"        android:right="10dp"        android:bottom="10dp" /></shape>

set it as the background in your layout xml

android:background="@drawable/dialog_bg"

Set the background of the dialog's root view to transparent, because Android puts your dialog layout within a root view that hides the corners in your custom layout.

dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

You need to do the following:

• Create a background with rounded corners for the Dialog's background:

  <?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android"android:shape="rectangle" >    <solid android:color="#fff" />    <corners        android:bottomLeftRadius="8dp"        android:bottomRightRadius="8dp"        android:topLeftRadius="8dp"        android:topRightRadius="8dp" /></shape>

• Now in your Dialog's XML file in the root layout use that background with required margin:

  android:layout_marginLeft="20dip"android:layout_marginRight="20dip"android:background="@drawable/dialog_background"

• finally in the java part you need to do this:

  dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);dialog.setContentView(layoutResId);View v = getWindow().getDecorView();v.setBackgroundResource(android.R.color.transparent);

This works perfectly for me.

dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

this works for me
