如何清除选项菜单图标?

将溢出菜单项设置为在xml中不可见:

<item android:id="@+id/action_settings"
    android:title="@string/action_settings"
    android:orderInCategory="100"
    app:showAsAction="never"
    android:visible="false"/>

或在CreateOptionsMenu上删除它:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    menu.findItem(R.id.action_settings).setVisible(false);

    return true;
}

MenuItem item = menu.findItem(R.id.addAction);
item.setVisible(false)

ActivityCompat.invalidateOptionsMenu(YourAtivity.this)

在API上<11使用

supportInvalidateOptionsMenu() method
