Question

我想制作地图活动，我想在操作栏中添加2个按钮。我使用Android Studio 0.8.4创建了项目，但我无法将菜单添加到操作栏。请帮助我

mapview.xml：

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/map"
tools:context=".MapsActivity"
android:name="com.google.android.gms.maps.SupportMapFragment"/>

Maps Activity.java

public class MapsActivity extends FragmentActivity implements LocationListener
{@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater menuInflater = getMenuInflater();
        menuInflater.inflate(R.menu.mapmenu, menu);

        // Calling super after populating the menu is necessary here to ensure that the
        // action bar helpers have a chance to handle this event.
        return true;
}

mapmenu.xml

<?xml version="1.0" encoding="utf-8"?>

<menu xmlns:tools="http://schemas.android.com/tools"
 xmlns:android="http://schemas.android.com/apk/res/android" >



<item android:id="@+id/action_search"
    tools:ignore="AppCompatResource"
    android:orderInCategory="50"
    android:icon="@android:drawable/ic_menu_search"
    android:title="Caută"
    tools:showAsAction="ifRoom"/>
<item android:id="@+id/action_cagain"
    android:icon="@drawable/ic_action_refresh"
    android:title="Încearcă din nou"
    android:orderInCategory="50"
    tools:ignore="AppCompatResource"
    tools:showAsAction="ifRoom"/>

清单：

<activity
        android:configChanges="orientation|screenSize"
        android:name=".MapsActivity"
        android:uiOptions="splitActionBarWhenNarrow"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="com.ferenczandras.transportmures.HARTA" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

谢谢

Answer 1

尝试使用 - ＆gt;工具：showAsAction = “总是”

<item android:id="@+id/action_search"
    tools:ignore="AppCompatResource"
    android:orderInCategory="50"
    android:icon="@android:drawable/ic_menu_search"
    android:title="Caută"
    tools:showAsAction="always"/>
<item android:id="@+id/action_cagain"
    android:icon="@drawable/ic_action_refresh"
    android:title="Încearcă din nou"
    android:orderInCategory="50"
    tools:ignore="AppCompatResource"
    tools:showAsAction="always"/>

Answer 2

请尝试使用tools:showAsAction="ifRoom"

，而不是使用android:showAsAction="always"

Answer 3

更改主题...默认的MAPACTIVITY THeme不会显示活动栏..要么完全从Manifest中的标签中删除它们，要么将其更改为显示操作栏的主题。

这应该记录得更好，但是这样做会显示菜单。

地图活动操作栏菜单按钮
