Calling android dialog without it fading the background

I have this nice dialog view I set my UserInputDialog class to:

    <LinearLayout android:id="@+id/LinearLayout01" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical"
    xmlns:android="http://schemas.android.com/apk/res/android">

        <TextView
        android:id="@+id/nameMessage"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="What is your name Captain?"
        >
        </TextView>
        <EditText
        android:id="@+id/nameEditText"
   开发者_高级运维     android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textSize="18sp"
        >
        </EditText>
    <LinearLayout android:id="@+id/LinearLayout02" android:layout_width="fill_parent" android:layout_height="wrap_content" 
        android:layout_gravity="center_horizontal">
    <Button
        android:id="@+id/okButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="OK">
        </Button>
        <Button android:id="@+id/cancelButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Cancel">
        </Button>               
    </LinearLayout>
</LinearLayout>

I want my dialog to show up but for the background to not fade out. Is this possible? Cause the view that calls this dialog has a neato background I would like to be shown as a backdrop to the dialog.

I found this online:

<style name="doNotDim" parent="@android:style/Theme.Dialog">
    <item name="android:backgroundDimAmount">0</item>
</style >

but not sure how to apply that to my dialog? I have a class called public class UserInputDialog extends Dialog implements OnClickListener. It sets its content view to the layout described above.

I think I am doing this all right, just not sure how to add that style so I can NOT fade the background.

Secondary question: Can you get new looks on your dialog (by say having an image or icon display with your text there) by using Themes?

You can also remove the dim effect by code with the following:

dialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);

Create a res/values/styles.xml file and add this to it.

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <style name="Theme.DoNotDim" parent="android:Theme">
    <item name="android:backgroundDimEnabled">false</item>
  </style>
</resources>

And apply the theme to your activity.

<activity android:name=".SampleActivity" android:theme="@style/Theme.DoNotDim">

Create a custom style and place it in your values folder

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <style name="YourCustomStyle" parent="android:Theme">
    <item name="android:backgroundDimEnabled">false</item>
  </style>
</resources> 

To set a style to an individual dialog you can use

Dialog dialog = new Dialog(context, R.style.YourCustomStyle);

For displaying dialog like TrueCaller do this:

In styles.xml file.

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <style name="myBackgroundStyle" parent="android:Theme.Dialog">
    <item name="android:backgroundDimEnabled">false</item>
  </style>
</resources>

In AndroidManifest.xml do this:

<activity android:name=".SampleActivity" android:theme="@style/myBackgroundStyle">
