I have a menu for my main activity (res/menu/main_menu.xml) and I want only one item on the Actionbar and the rest shall be hidden under three dots menu.
The problem is, I never see the three dots item on my actionbar. Why I can't see three dots item? How to force items to be hidden under it?
Note: I use minSdkVersion="14" and I test in AVD.
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item android:id="@+id/menu_item_share"
android:title="@string/share"
android:icon="@android:drawable/ic_menu_share"
app:showAsAction="ifRoom"
android:actionProviderClass="android.widget.ShareActionProvider" />
<item
android:id="@+id/empty"
android:title="@string/options"
android:orderInCategory="101"
app:showAsAction="always"
android:icon="@drawable/baseline_more_vert_black">
<menu>
<item android:id="@+id/action_settings"
android:icon="@android:drawable/ic_menu_preferences"
app:showAsAction="ifRoom"
android:title="@string/settings" />
<item android:id="@+id/action_help"
android:icon="@android:drawable/ic_menu_help"
app:showAsAction="ifRoom"
android:title="@string/help" />
</menu>
</item>
</menu>
You will need to add the baseline_more_vert_black icons to your res/drawable... folders once you've downloaded them from here.
try this;
menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/menu_new_content_facebook"
android:orderInCategory="100"
android:title="@string/str_share_facebook"
app:showAsAction="never" />
<item
android:id="@+id/menu_new_content_twitter"
android:orderInCategory="200"
android:title="@string/str_share_twitter"
app:showAsAction="never" />
</menu>
MainActivity.java
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if(id == R.id.menu_new_content_twitter){
// do something
}
return super.onOptionsItemSelected(item);
}
this solution provided by ban-geoengineering is one very intresting... 3 dot icon sometimes doesn't display if you use android:showAsAction namespace android: instead custom namespace like:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/taskNotificationsBtn"
app:showAsAction="always"
android:icon="@drawable/tasks"/>
But solution provided by ban-geoengineering help me to solve problem with reversing ActionBar items direction to match this to Arabic layout. I have used ActionBarRTLizer library and standard approach with android os 3dots causes some bug when menu item icons cover each other sometimes (very frustratign situation), but this custom solution
<item
android:id="@+id/empty"
android:title="@string/options"
android:orderInCategory="101"
android:showAsAction="always"
android:icon="@drawable/ic_action_overflow">
<menu>
<item android:id="@+id/action_settings"
android:icon="@android:drawable/ic_menu_preferences"
android:showAsAction="ifRoom"
android:title="@string/settings" />
<item android:id="@+id/action_help"
android:icon="@android:drawable/ic_menu_help"
android:showAsAction="ifRoom"
android:title="@string/help" />
</menu>
</item>
solved the problem and RTL works perfectly well! :)
This may also be helpful if you want to handle hardware menu buttons:
@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_MENU) {
// do stuff
return true;
} else {
return super.onKeyUp(keyCode, event);
}
}
and add here: mMenuReference.performIdentifierAction(R.id.menu_0, 1);
in order to replace Sub Menu displayed as overflow menu depending for example on current Activity you could use this solution:
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate your main_menu into the menu
getMenuInflater().inflate(R.menu.main_menu, menu);
// Find the menuItem to add your SubMenu
MenuItem myMenuItem = menu.findItem(R.id.my_menu_item);
// Inflating the sub_menu menu this way, will add its menu items
// to the empty SubMenu you created in the xml
getMenuInflater().inflate(R.menu.sub_menu, myMenuItem.getSubMenu());
}
Why I can't see three dots item?
Your emulator is emulating a device that has a MENU button. If there is a MENU button on the device, the MENU button brings up the overflow.
The solution can be found here https://stackoverflow.com/a/27502405/1808829, which worked perfect for me. No need to work with xml staff, it is done only programatically.
private void getOverflowMenu() {
try {
ViewConfiguration config = ViewConfiguration.get(this);
Field menuKeyField = ViewConfiguration.class.getDeclaredField("sHasPermanentMenuKey");
if(menuKeyField != null) {
menuKeyField.setAccessible(true);
menuKeyField.setBoolean(config, false);
}
} catch (Exception e) {
e.printStackTrace();
}
}
