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

//code style in style.xml :

// 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);
