Android : AccountPicker set Light Theme

问题:

Is it possible to set the theme of picker dialog ?

import com.google.android.gms.common.AccountPicker;
....
String[] accountTypes = new String[]{"com.google"};
Intent intent = AccountPicker.newChooseAccountIntent(null, null,
                accountTypes, false, null, null, null, null);
activity.startActivityForResult(intent, REQUEST_CODE_PICK_ACCOUNT);

My base app theme is android:Theme.Light but that dialog is dark. Thanks.

If you wish to change the theme of the dialog, you should change the newChooseAccountIntent to zza and add two integer arguments. The first one is for overriding the theme and setting it to 1 will change the dialog theme to light.

String[] accountTypes = new String[]{"com.google"};
Intent intent = AccountPicker.zza(null, null, accountTypes, false, null, null, null, null, false, 1, 0);
startActivityForResult(intent, REQUEST_CODE_PICK_ACCOUNT);

you can change it when you overwrite over any args are defined in a parent class in method newChooseAccountIntent(Account var0, ArrayList<Account> var1, String[] var2, boolean var3, String var4, String var5, String[] var6, Bundle var7) {}

it is very simple to change it by adding it to your code...

Intent intent = AccountPicker.newChooseAccountIntent(null, null, new String[]{GoogleAuthUtil.GOOGLE_ACCOUNT_TYPE}, false, null, null, null, null). putExtra("overrideTheme", 1); startActivityForResult(intent, REQUEST_CODE_EMAIL);

1 means the Light Theme

0 means the Dark Theme

When your Accountpicker is declared (I don't know much about AccountPicker) you can set the theme, but it could also be possible that it is this theme, cause it's by the system

EDIT: there's the reason

but I think you could modify it :)
