点击上显示“溢出”菜单。
菜单/ menu_scrollable_tab.xml
ImageButton我已禁用默认操作栏并使用布局创建了操作栏。我没有使用默认操作栏或工具栏，因为我需要更多地自定义操作栏。
布局/ actionbar.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
tools:context="com.example.scrollingtab.activity.ScrollableTabsActivity">
<item android:id="@+id/action_settings"
android:title="@string/action_settings"
android:orderInCategory="100"
app:showAsAction="always"
android:icon="@drawable/info" />
<item android:id="@+id/action_settings1"
android:title="@string/action_settings"
android:orderInCategory="100"
app:showAsAction="never" />
<item android:id="@+id/action_settings2"
android:title="@string/action_settings"
android:orderInCategory="100"
app:showAsAction="never" />
</menu>
根据客户要求，我使用布局设计了操作栏，外观很好。
默认的<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="50dp" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="50dp"
android:orientation="horizontal"
android:background="@color/actionbar_bg"
android:weightSum="2">
<ImageButton android:id="@+id/ib_navigation"
android:background="@drawable/nv_drawer_24x24"
android:layout_width="0dp"
android:layout_weight=".3"
android:layout_height="50dp"/>
<View
android:layout_width="0dp"
android:layout_height="50dp"
android:layout_weight="1.1"/>
<ImageButton android:id="@+id/ib_navigation1"
android:background="@drawable/info"
android:layout_width="0dp"
android:layout_weight=".3"
android:layout_height="50dp"/>
<ImageButton android:id="@+id/ib_navigation2"
android:background="@drawable/ic_drawer"
android:layout_width="0dp"
android:layout_weight=".3"

</LinearLayout>
</RelativeLayout>
方法没有填充溢出菜单。现在，我想在点击OnCreateOptionsMenu(Menu menu) ImageButton时填充溢出菜单。我不知道如何实现这一点。
任何人都可以帮我这么做。
由于
答案 0 :(得分：0)
您需要覆盖创建自己菜单的方法
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.game_menu, menu);
return true;
}
按钮点击可以调用openOptionsMenu();
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
openOptionsMenu();
}
});
否则
public myOnClickMethod(View v) {
openOptionsMenu();
}
有关菜单的详细信息，请参见此处 http://developer.android.com/guide/topics/ui/menus.html
希望这对你有用
