華為手機設置桌面圖標角標提醒的實現

華為手機用戶占有率已經很大，有必要為華為手機支持角標提醒。

首先，要參考官網文檔。

實現

　　1. 申請許可權，這裡有點多，還包含了其他手機的。官方文檔的許可權是不夠的。

<uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="com.huawei.android.launcher.permission.CHANGE_BADGE"/>

    <uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT"/>
    <uses-permission android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT"/>
    <uses-permission android:name="com.android.launcher2.permission.READ_SETTINGS"/>
    <uses-permission android:name="com.android.launcher2.permission.WRITE_SETTINGS"/>

    <uses-permission android:name="org.adw.launcher.permission.WRITE_SETTINGS"/>
    <uses-permission android:name="com.htc.launcher.permission.READ_SETTINGS"/>
    <uses-permission android:name="com.htc.launcher.permission.WRITE_SETTINGS"/>
    <uses-permission android:name="com.qihoo360.launcher.permission.READ_SETTINGS"/>
    <uses-permission android:name="com.qihoo360.launcher.permission.WRITE_SETTINGS"/>

    <uses-permission android:name="org.adw.launcher_donut.permission.WRITE_SETTINGS"/>
    <uses-permission android:name="com.huawei.launcher3.permission.READ_SETTINGS"/>
    <uses-permission android:name="com.huawei.launcher3.permission.WRITE_SETTINGS"/>
    <uses-permission android:name="com.fede.launcher.permission.READ_SETTINGS"/>
    <uses-permission android:name="com.fede.launcher.permission.WRITE_SETTINGS"/>
    <uses-permission android:name="com.sec.android.app.twlauncher.settings.READ_SETTINGS"/>
    <uses-permission android:name="com.sec.android.app.twlauncher.settings.WRITE_SETTINGS"/>
    <uses-permission android:name="com.anddoes.launcher.permission.READ_SETTINGS"/>
    <uses-permission android:name="com.anddoes.launcher.permission.WRITE_SETTINGS"/>
    <uses-permission android:name="com.tencent.qqlauncher.permission.READ_SETTINGS"/>
    <uses-permission android:name="com.tencent.qqlauncher.permission.WRITE_SETTINGS"/>
    <uses-permission android:name="com.huawei.launcher2.permission.READ_SETTINGS"/>
    <uses-permission android:name="com.huawei.launcher2.permission.WRITE_SETTINGS"/>
    <uses-permission android:name="com.android.mylauncher.permission.READ_SETTINGS"/>
    <uses-permission android:name="com.android.mylauncher.permission.WRITE_SETTINGS"/>
    <uses-permission android:name="com.ebproductions.android.launcher.permission.READ_SETTINGS"/>
    <uses-permission android:name="com.ebproductions.android.launcher.permission.WRITE_SETTINGS"/>
    <uses-permission android:name="com.oppo.launcher.permission.READ_SETTINGS"/>
    <uses-permission android:name="com.oppo.launcher.permission.WRITE_SETTINGS"/>
    <uses-permission android:name="com.lenovo.launcher.permission.READ_SETTINGS"/>
    <uses-permission android:name="com.lenovo.launcher.permission.WRITE_SETTINGS"/>
    <uses-permission android:name="com.huawei.android.launcher.permission.READ_SETTINGS"/>
    <uses-permission android:name="com.huawei.android.launcher.permission.WRITE_SETTINGS"/>
    <uses-permission android:name="telecom.mdesk.permission.READ_SETTINGS"/>
    <uses-permission android:name="telecom.mdesk.permission.WRITE_SETTINGS"/>
    <uses-permission android:name="dianxin.permission.ACCESS_LAUNCHER_DATA"/>

　　2. 官方代碼。需要註意包名和類名必須正確，否則無反應

public void SetBadge(int num){
        try{
            String pName= getPackageName();
            Toast.makeText(MainActivity.this, pName, Toast.LENGTH_LONG).show();
            Bundle bunlde =new Bundle();
            bunlde.putString("package", "com.test.badge.example"); // 包名
            bunlde.putString("class", "com.test.badge.example.MainActivity"); //類名
            bunlde.putInt("badgenumber",num);
            Bundle res= this.getContentResolver().call(Uri.parse("content://com.huawei.android.launcher.settings/badge/"), "change_badge", null, bunlde);
        }catch(Exception e){
            Toast.makeText(MainActivity.this, e.getMessage(), Toast.LENGTH_LONG).show();
        }
    }
