Remove black background on custom dialog

Question

I want to remove the black background on custom dialog as shown in the picture. I\'m sure the black background was from the dialog, not from app\'s background.

Answer 1

you can create xml layout like following and set that layout on dialog(dialog.xml) :

<?xml version="1.0" encoding="utf-8"?>
<ScrollView android:id="@+id/ScrollView01"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android" style="@style/white_background_bl_aatharv">

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical" android:layout_width="fill_parent"
        android:layout_height="wrap_content" android:scrollbars="vertical"
        android:scrollbarAlwaysDrawVerticalTrack="true" android:id="@+id/instructions_view">

        <TextView android:id="@+id/TextView01" android:layout_width="wrap_content"
            android:layout_height="wrap_content" android:textColor="#FFFFFF"
            android:text="text here " />
    </LinearLayout>
</ScrollView>

here is the code to set layout on alert dialog :

AlertDialog alert = cndtnsbuilder.create();
alert.setView(LayoutInflater.from(
currentactivity.this).inflate(
R.layout.dialog, null));
alert.show();

Answer 2

To remove the background color, on layout, you just need to set the background to @null

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@null">

Answer 3

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

Answer 4

Following method worked for me:

getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

Answer 5

//code style in style.xml :

<style name="translucentDialog" parent="android:Theme.Holo.Dialog">
    <item name="android:windowBackground">@android:color/transparent</item>
</style>

// in activity :set style to dialog :

   Dialog dialogconf = new Dialog(TreeAct.this, R.style.translucentDialog);
            dialogconf.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
                   dialogconf.setContentView(R.layout.dialog_layout);

Answer 6

Just change Dialog parent them.

With black backround

<style name="MyDialog2" parent="@android:Theme.Dialog">        

Without black background

<style name="MyDialog2" parent="@android:style/Theme.DeviceDefault.Light.Dialog">
