工具栏菜单不再起作用

Question

I changed from a normal ActionBar to the new Toolbar. My problem is that my old menu doesn't work. When I click on the overflow icon nothing happens. I'm using appcompat v7 but I could not find any solution. Can someone help me?

Menufunctions:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu
    getMenuInflater().inflate(R.menu.chatmenu, menu);

    return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case R.id.onlineliste:
        getOnlineList();
        return true;
    case R.id.settings:
        showSettings();
        return true;
    case R.id.logout:
        logout();
        return true;
    default:
        return super.onOptionsItemSelected(item);
    }
}

Chatmenu:

        <?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/onlineliste" 
    android:title="@string/userliste"
    app:showAsAction="always">
</item>
<item 
          android:id="@+id/settings" 
          android:title="@string/settings" 
          app:showAsAction="never">
</item>
    <item 
          android:id="@+id/logout" 
          android:title="@string/logout" 
          app:showAsAction="never">
</item>
</menu>

Theme

<style name="AppTheme.Base" parent="Theme.AppCompat.Light">
    <item name="colorPrimary">#428bca</item>
    <item name="colorPrimaryDark">#428bca</item>
    <item name="android:windowNoTitle">true</item>
    <item name="theme">@style/ThemeOverlay.AppCompat.Dark</item>
    <item name="windowActionBar">false</item>
</style>

Toolbar

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="?attr/actionBarSize"
    android:background="?attr/colorPrimaryDark" />

Answer 1

Oh my godness I got it. Thank you for all your help guys! The problem was that I had a RelativeLayout which was overlapping the toolbar but I did not see this directly. THe solution was to add

android:layout_below="@+id/toolbar" to the relativ layout and now everything works fine.

Again thanks for all your help guys and sorry!

Answer 2

try this one:

<?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/onlineliste" 
    android:visible="true" 
    android:title="@string/userliste" 
    app:showAsAction="never">
</item>
<item 
          android:id="@+id/settings" 
          android:visible="true" 
          android:title="@string/settings" 
          app:showAsAction="never">
</item>
    <item 
          android:id="@+id/logout" 
          android:visible="true" 
          android:title="@string/logout" 
          app:showAsAction="never">
</item>

also your theme must have a parent of Theme.AppCompat and your Activity must extends from ActionBarActivity

Answer 3

Probably you need to set your Toolbar as the activity ActionBar, using:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.your_layout);

    Toolbar toolbar = (Toolbar) findViewById(R.id.your_toolbar);
    setSupportActionBar(toolbar);

Answer 4

You are not returning true from the onCreateOptionMenu().

The documentation says that

You must return true for the menu to be displayed; if you return false it will not be shown.

Insead of

return super.onCreateOptionsMenu(menu);

which always return false. Return true from onCreateOptionsMenu(menu);

Check out the documentation here. Source Link
