Android - Custom AlertDialog Background Color
Instead of using AlertDialog, I ended up using a Dialog. To get a custom look:
1-Create the Dialog and remove the title area(Otherwise you'll get a blank gray area on top):
myDialog = new Dialog(this);
myDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
2-Design a layout in xml, and set as dialog's content:
myDialog.setContentView(R.layout.mydialog_layout);
3-If the layout is not a rounded rect, it will intersect with the rounded corners of the dialog box. So, design the layout as a rounded rect:
in mydialog_layout.xml:
android:background = "@layout/mydialog_shape"
mydialog_shape.xml:
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle"
>
<gradient android:startColor="#FF0E2E57"
android:endColor="#FF0E2E57"
android:angle="225" android:paddingLeft="20dip"/>
<corners android:bottomRightRadius="5dp" android:bottomLeftRadius="5dp"
android:topLeftRadius="5dp" android:topRightRadius="5dp" android:paddingLeft="20dip"/>
</shape>
4-Add listeners to the buttons in your activity:
Button button = (Button)myDialog.findViewById(R.id.dialogcancelbutton);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
myDialog.cancel();
}});
That's about it.

So I see we can have alertdialogs with gray and white (when setinverse...) background colors.
To learn why I checked themes.xml of the sdk, checking it I was led to drawables and there I realized the alertdialog background is not done programatically but via some images. And these images guarantee that there are two gray(or white when inverse color) horizontal lines on top(title area) and bottom(just above button area) of the dialog when we use LayoutInflater to just set a different backgroundcolor.
So my question is, as LayoutInflator is useless and guessing I have to subclass alertdialog, what do you suggest I do to generate an AlertDialog with a different backgroundcolor? What should I override?

ahmet emrah over 13 years+1 Thx for the answer. So what methods should I override to get a functional custom dialog?

Anthony Graglia over 13 yearsYou can also do this with alert... you just have to inflate the layout first with layoutinflator and then it is the same but easier to assign an icon and title.
