Custom dialog on Android: How can I center its title?

Question

I\'m developing an Android application.

How can I center the title for a custom dialog that I\'m using?

Answer 1

You can do it programmatically without custom view:

@Override
public void onStart()
{
    super.onStart();

    TextView textViewVanilla = (TextView) this.getDialog().findViewById(android.R.id.title);
    if(textViewVanilla != null)
    {
        textViewVanilla.setGravity(Gravity.CENTER);
    }
    // support for appcompat v7
    TextView textViewAppcompat = (TextView) this.getDialog().findViewById(android.support.v7.appcompat.R.id.alertTitle);
    if(textViewAppcompat != null)
    {
        textViewAppcompat.setGravity(Gravity.CENTER);
    }
}

Thanks @hesam for the idea. For appcompat layout see Android/sdk/platforms/android-26/data/res/layout/alert_dialog_title_material.xml
