I'm struggling with the toolbar and drawer. I'm trying to make the burger switch to arrow when I'm adding a new fragment to the backstack but there is no way to do it.
Maybe I'm missing something but I could not find a way. Anyone had the same problem?
This is the declaration:
mDrawerToggle = new ActionBarDrawerToggle(
getActivityCompat(), /* host Activity */
mDrawerLayout, /* DrawerLayout object */
((BaseActivity) getActivityCompat()).getToolbar(),
R.string.navigation_drawer_open, /* "open drawer" description for accessibility */
R.string.navigation_drawer_close /* "close drawer" description for accessibility */
)
This is the function I call when a fragment is added to the back stack
public void setToggleState(boolean isEnabled) {
if (mDrawerLayout == null)
return;
if (isEnabled) {
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
mDrawerToggle.onDrawerStateChanged(DrawerLayout.LOCK_MODE_UNLOCKED);
} else {
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
mDrawerToggle.onDrawerStateChanged(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
}
mDrawerToggle.syncState();
}
I think all you have to do is to delete the third argument. Thus:
mDrawerToggle = new ActionBarDrawerToggle(
getActivityCompat(), /* host Activity */
mDrawerLayout, /* DrawerLayout object */
// ((BaseActivity) getActivityCompat()).getToolbar(), <== delete this argument
R.string.navigation_drawer_open, /* "open drawer" description for accessibility */
R.string.navigation_drawer_close /* "close drawer" description for accessibility */
);
May it helps.
