同步类.java

public class SyncClass extends Application {

menu_main.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"      tools:context=".MainActivity"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
    android:id="@+id/action_settings"
    android:title="@string/action_settings"
    android:orderInCategory="100"
    app:showAsAction="never" />
<item
    android:id="@+id/menu_item_share"
    app:showAsAction="ifRoom"
    android:title="Share"
    android:actionProviderClass="android.widget.ShareActionProvider" />

此外，我想将 Material Design 主题应用到我的项目中。我已经完成了以下操作:-

Android list :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.musicginni" >
<uses-sdk
    android:minSdkVersion="14"
    android:targetSdkVersion="21" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.VIBRATE"/>
<application
    android:allowBackup="true"
    android:icon="@drawable/iconw"
    android:theme="@style/Theme.AppCompat"
    android:name=".SyncClass">
    <activity
        android:name=".StartUp"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAINACTIVITY" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
</application>

</manifest>

这是 styles.xml(v21) 文件

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="AppTheme" parent="android:Theme.Material.Light">
    <item name="android:colorPrimary">#ff95609b</item>
    <item name="android:colorPrimaryDark">#ff644469</item>
    <item name="android:textColorPrimary">#fff8f7ec</item>
    <item name="android:windowBackground">@color/custom_theme_color</item>
    <item name="android:navigationBarColor">#ff403a25</item>
</style>
<color name="custom_theme_color">#ffffffff</color>
</resources>

样式.xml文件

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="android:Theme.Holo.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="android:actionBarStyle">@style/MyActionBar</item>
    <item name="android:absListViewStyle">@style/MyListView</item>
</style>
<style name="MyActionBar" parent="@android:style/Widget.Holo.Light.ActionBar">
    <item name="android:background">#ff774d7d</item>
</style>
<style name="MyListView" parent="@android:style/Widget.Holo.Light.ListView">
    <item name="android:background">#ffb3aac6</item>
</style>

</resources>

在我编译 appcompat v7 库并使用 ActionBarActivity 而不是 Activity 之前， Material 设计工作正常。

Answer 1

更改为:

<item
    android:id="@+id/menu_item_share"
    app:showAsAction="ifRoom"
    android:title="Share"
    app:actionProviderClass="android.support.v7.widget.ShareActionProvider"    />

和:

 @Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_main, menu);
    MenuItem item = menu.findItem(R.id.menu_item_share);
    ShareActionProvider MenuSAP = (ShareActionProvider)  MenuItemCompat.getActionProvider(item);
    MenuSAP.setShareIntent(createShareIntent());
    return super.onCreateOptionsMenu(menu);
}

如果你使用 progaurd 你需要这个:

-keep class android.support.v7.widget.ShareActionProvider { *; }

编辑试试这个:

    getMenuInflater().inflate(R.menu.menu_main, menu);
    new ShareActionProvider(this).setShareIntent(createShareIntent());

    return super.onCreateOptionsMenu(menu);
