android - 在静态快捷方式中实现共享应用工具

Question

我试图在 Android(如 iOS 平台)中将“共享应用程序”工具实现为应用程序快捷方式。即使没有打开应用程序，此工具也必须在安装后立即存在。我想知道如何在快捷方式 xml 文件中使用此 Intent :

Intent intent = new Intent();
        intent.setAction(Intent.ACTION_SEND);
        intent.putExtra(Intent.EXTRA_TEXT, "https://www.example.com");
        intent.setType("text/plain");

Answer 1

我没有找到任何方法来将 Intent 的 type 属性放入 xml 中。但似乎一个无形主题的 Activity 可以模拟我想要的。

作为documentation说:

Start one activity from another

Static shortcuts cannot have custom intent flags. The first intent of a static shortcut will always have Intent.FLAG_ACTIVITY_NEW_TASK and Intent.FLAG_ACTIVITY_CLEAR_TASK set. This means, when the app is already running, all the existing activities in your app are destroyed when a static shortcut is launched. If this behavior is not desirable, you can use a trampoline activity, or an invisible activity that starts another activity in Activity.onCreate(Bundle), then calls Activity.finish():

In the AndroidManifest.xml file, the trampoline activity should include the attribute assignment android:taskAffinity="". In the shortcuts resource file, the intent within the static shortcut should reference the trampoline activity. For more information about trampoline activities, read Start one activity from another.

我们可以将 android:taskAffinity="" 添加到 manifest 文件中的 InvisibleActivity 以防止应用程序在单击主页按钮时进入后台。

这是我在 AndroidManifest.xml 中设置的隐形 Activity

<activity
    android:name=".InvisibleActivity"
    android:excludeFromRecents="true"
    android:taskAffinity=""
    android:noHistory="true"
    android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen" />

这是我不可见 Activity 中的整个 onCreate() 方法:

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    Intent sendIntent = new Intent();
    sendIntent.setAction(Intent.ACTION_SEND);
    sendIntent.putExtra(Intent.EXTRA_TEXT, "https://www.example.com");
    sendIntent.setType("text/plain");
    startActivity(sendIntent);
    finish();
}

最后这是我的静态快捷方式 xml 文件:

<shortcut
    android:enabled="true"
    android:shortcutId="share_app_shortcut"
    android:icon="@drawable/ic_share"
    android:shortcutShortLabel="@string/shortcut_share_description">

    <intent
        android:action="android.intent.action.VIEW"
        android:targetClass=".InvisibleActivity"
        android:targetPackage="com.example.shortcut">
    </intent>

</shortcut>
