AlertDialog theme problems

Question

I'm creating an AlertDialog. If create it like this:

AlertDialog.Builder builder = AlertDialog.Builder((RelationActivity)getContext());
builder.setMessage("No relations found.");
builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {       
    public void onClick(DialogInterface dialog, int id) {
        ((RelationActivity)getContext()).finish();
    }
});
builder.create();
builder.show();

This is the result: http://www.ozze.com.br/1.png

But, if I try to set a theme, like this:

AlertDialog.Builder builder = new AlertDialog.Builder(((RelationActivity)getContext()), android.R.style.Theme_Holo_Light_Dialog);

This is the result: http://www.ozze.com.br/2.png

Please, can anyone help me with this issue? It looks like when using a theme, the theme "surrounds" the alert dialog.

Answer 1

To set a different Theme for the alert dialog like Theme.Holo.Light try to use ContextThemeWrapper as used in Dialog.java in android source:

builder = new AlertDialog.Builder(new ContextThemeWrapper(this, android.R.style.Theme_Holo_Light_Dialog))

Answer 2

Here is link of Original answer here

For quick reference I am posting here
Theme with v7 library android.support.v7.app.AlertDialog

android.support.v7.app.AlertDialog.Builder builder = new android.support.v7.app.AlertDialog.Builder(this,R.attr.alertDialogTheme);

Theme with constructer for android.app.AlertDialog

android.app.AlertDialog.Builder builder = new android.app.AlertDialog.Builder(this,AlertDialog.THEME_HOLO_LIGHT );

But as per new documentation
This constant(AlertDialog.THEME_HOLO_LIGHT) was deprecated in API level 23. Use Theme_Material_Light_Dialog_Alert .

 android.app.AlertDialog.Builder builder = new android.app.AlertDialog.Builder(this,android.R.style.Theme_Material_Light_Dialog_Alert );
