Static dialog with TextView

Question

what`s wrong with this because I cant compile to apk. Error is Cannot use this in a static context but if I change this to context app freeze when dialog must appear.

public static void mydialog(final Context context) {
    AlertDialog.Builder builder = new AlertDialog.Builder(context);
    TextView myMsg = new TextView(this);
    myMsg.setText("Central");
}

Logcat error:

 android.view.WindowLeaked: Activity com.test.testapp.activities.MenuActivity has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView{430fc9a8 V.E..... R.....I. 0,0-1048,466} that was originally added here

Why do you need a static method to show a Dialog ? – 2Dee May 27 '15 at 13:56 — 2Dee, May 27 '15 at 13:56

A static method is not associated with any particular instance of a class. It is a method associated with the class itself. Thus this has no meaning in a static method- there is no instance of the class to reference.

If this method is in a class that is a Context (e.g. an Application subclass or an Activity), then you can remove the static modifier and use this like you are already trying to do.

but what if I want to keep static method? How can I modify TextView(this) to show proper text in dialog? – Desmo May 27 '15 at 14:04

Switching `this` to `context` should work, but without seeing your logcat from when it freezes it is difficult to say why that wouldn't work for you- it should work just fine. – Bryan Herbst May 27 '15 at 14:05
Arhh...Thanks, solve the problem! :) I forgot to include setView. Just want to know; why is in my method text smaller than if I set builder.setMessage("Message")? – Desmo May 27 '15 at 14:13

You don't appear to be applying any sort of styling to your TextView. AlertDialogs typically use ` style="?android:attr/textAppearanceMedium"` for the message in their XML layout, so you will want to do something similar if you want the same styling. – Bryan Herbst May 27 '15 at 14:18
Thanks. Now I was detect crash issue. If I change orentation of the phone app crashed. I was paste logcat in original post. Is this related to my TextView? – Desmo May 27 '15 at 14:33
