above is my MainActivity file code. i implementing simple navigationdrawer with custom actionbar. that's why drawer icon not showing in some devices. if i used default actionbar than it works fine.
below is my output:
help me for solve this bug.
Sagar Maiyad
I solved my problem by replacing:
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setDisplayUseLogoEnabled(false);
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setHomeButtonEnabled(true);
actionBar.setIcon(null);
with:
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM | ActionBar.DISPLAY_SHOW_HOME | ActionBar.DISPLAY_HOME_AS_UP);
actionBar.setIcon(android.R.color.transparent);
More correct answer is this.
As per warning from log,
W/ActionBarDrawerToggle(28554): DrawerToggle may not show up because Navigation Icon is not visible. You may need to call actionbar.setDisplayHomeAsUpEnabled(true);
