Android dialogue transparent

Question

I want to get rid of the border in my dialog box and make it completely transparent, as if the image were at the top of the screen.

My xml dialog is

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

 <ImageView android:id="@+id/ImageView01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:visibility="invisible"/> 

Answer 1

Try entering the code

 Dialog mDialog = new Dialog(mContext, android.R.style.Theme_Translucent_NoTitleBar_Fullscreen); 

Answer 2

try the following:

 mDialog.getWindow().setBackgroundDrawable(new ColorDrawable(0)); 

Answer 3

To get a translucent effect, such as 50% opacity, use:

 Drawable d = new ColorDrawable(Color.BLACK); d.setAlpha(130); mDialog.getWindow().setBackgroundDrawable(d); 

'130' can be changed (0-255) to obtain the desired opacity.

Answer 4

try the following: -

 final Dialog dialog = new Dialog(this); dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT)); dialog.setContentView(R.layout.splash); dialog.show(); 

Answer 5

For API 11+

 Dialog mDialog = new Dialog(mContext, android.R.style.Theme_Holo_Light_Panel); 

Answer 6

The easiest way to do this is that in your DialogFragment onCreate () method, call

 setStyle(DialogFragment.STYLE_NO_FRAME, 0); 

And if the view that you returned to onCreateView has no background, the background of the dialog will be just transparent.

Why? DialogFragment.STYLE_NO_FRAME means that the OS will not do any drawing in the dialog box, and your view is 100% responsible for drawing everything about the dialog.
