How to change the background color around a DialogFragment?

Question

I\'m building a custom DialogFragment. The dialog layout is set to my_dialog.xml, but how can I modify the color around the dialog (the transparent

Answer 1

To get a fully transparent dialog, you can set in onCreateView the following

• setBackgroundDrawable to Color.TRANSPARENT
• setDimAmount to 0

See code example here:

public class TextEditor extends DialogFragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_text_editor, container);

        // make dialog itself transparent
        getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

        // remove background dim 
        getDialog().getWindow().setDimAmount(0);

        //[add more custom code here...]

        return view;
    }
}

Answer 2

change your Text Background on the XML i just edited your code replace it with yours

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" >

<TextView
    android:id="@+id/hello"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:gravity="center"
    android:text="hello" />

because you gave the TextView height and width of 100dp. and set a background for it that will fill the whole dialog. since your main layout is wrap_content. please do accept the answer if that helped you.
Edit : to change the background just add to your layout or to your textview android:background="#232323" you can change these number to any color you like. or you can set a background from the drawable like android:background="@drawable/yourpicturename"
