在Android中安装后无法在主屏幕上创建应用程序的快捷方式 [英] Unable to create application's shortcut on Home Screen upon installation in android

问题描述

我想在home screen上创建应用程序的快捷方式.

I want to create a shortcut of the application on home screen when it is installed.

我将此添加到了 AndroidManifest.xml

<activity
        android:name="com.example.test.ShortCutActivity"
        android:icon="@drawable/ic_launcher"
        android:label="@string/title_activity_short_cut" >

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

</activity>

我在我的项目中还创建了一个使用ShortCutActivity名称的Actvity.

Also I have a Actvity created with ShortCutActivity name in my project.

ShortCutActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    ShortcutIconResource icon =
            Intent.ShortcutIconResource.fromContext(this, R.drawable.ic_launcher);

        Intent intent = new Intent();

        Intent launchIntent = new Intent(this,MainActivity.class);

        intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, launchIntent);
        intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "ShortCut");
        intent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, icon);

        setResult(RESULT_OK, intent);
}

但是它没有创建任何快捷方式.我想念什么吗?

But it is not creating any shortcut. Am I missing something ?

推荐答案

在您的活动中使用此示例代码，该活动在AndroidManifest.xml中设置为LAUNCHER和MAIN

Use this sample code in your activity which is set as a LAUNCHER and MAIN in AndroidManifest.xml

private void createShortcut(){
     Intent shortcutIntent = new Intent(getApplicationContext(),MainActivity.class);
     shortcutIntent.setAction(Intent.ACTION_MAIN);
     Intent intent = new Intent();
     intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
     intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "ShortcutDemo");
     intent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE,Intent.ShortcutIconResource.fromContext(getApplicationContext(), R.drawable.ic_launcher));
     intent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
     getApplicationContext().sendBroadcast(intent);
}

还要在您的AndroidManifest.xml中应用以下权限

Also apply following permissions in your AndroidManifest.xml

  <uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" />
