Create shadow for dialog

Question

I want to create a shadow for my custom dialog is that possible ?

GhazalActivity.public void viewShareMenu() {
        Dialog share=new Dialog(this,R.style.shareDialogStyle);
        share.setContentView(R.layout.share_popup_layout);
        LayoutParams params = share.getWindow().getAttributes();
        params.y = this.getResources().getDimensionPixelSize(R.dimen.topbar_height);
        params.gravity=(Gravity.RIGHT|Gravity.TOP);
        share.getWindow().setAttributes(params);
        share.show();
}

styles.xml :

<style name="shareDialogStyle" parent="android:style/Theme.Dialog">
    <item name="android:windowBackground">@color/transparent</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:fadeEnabled">true</item>
    <item name="android:fadeDuration">1500</item>
    <item name="android:shadowColor">@color/temp</item>
    <item name="android:shadowDx">0</item>
    <item name="android:shadowDy">5</item>
    <item name="android:shadowRadius">10</item>
    <item name="android:backgroundDimEnabled">false</item>
</style>

share_popup_layout.xml :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="150dip"
    android:background="@color/bg_Ghazal_share_menu"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <Button
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:gravity="right"
        style="@style/shareDialogButtons"/>
</LinearLayout>

is there any solution for doing that ?

I have created my own custom dialog with a dropped shadow, you can use it as your desire, in the first step you should create a Android shape for both shadow and dialog frame. Here is what I have supplied (dialog_frame_shadow.xml):

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle"> <!-- this shape is used as shadow -->
            <padding android:bottom="5dp"
                android:left="5dp"
                android:right="5dp"
                android:top="5dp"/>
            <solid android:color="#44000000"/>
            <corners android:radius="5dp"/>
        </shape>
    </item>
    <item>
        <shape android:shape="rectangle"> <!-- this is for dialog frame -->
            <corners android:radius="5dp"/>
            <stroke android:color="#ff272727" android:width="2dp" />
            <gradient android:angle="90"
                android:startColor="#ffa7a7a7"
                android:centerColor="#ff6a6a6a"
                android:endColor="#ffa7a7a7"
                android:type="linear"/>
        </shape>
    </item>
</layer-list>

In the next step you should change your dialog theme as what is in the following:

 <style name="my_dialog_theme">
     ...
     <item name="android:windowBackground">@drawable/dialog_frame_shadow</item>
     ...
 </style>

Now you are done, just create a new instance of the Dialog class and apply this theme to it (in Dialog constructor):

Dialog dialog = new Dialog(this, R.style.my_dialog_theme);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.mdialog);
dialog.show();

Here is its screenshot:
