Android 桌面角標在各大品牌機型上的實現
阿新 • • 發佈：2019-02-15
由於角標在Android原生的系統中沒有支援，所以各個Android手機廠商各自為政。
正如很多資料所說，這一功能完全是效仿IOS，Android本不存在的，對於不支援的廠商如魅族、中興、酷派，必須為他們不盲目跟風而點贊。
做起適配來，真的很麻煩，要針對各個廠商逐個去寫以及測試。
目前做到支援小米、華為、三星、LG、VIVO、ZUK、HTC、NOVA等廠商的Andorid系統
效果如下圖所示
特別說明一下小米自MIUI6.0以後，角標的顯示和通知欄Notification綁在一起。目前我發現的做法，就只有小米需要和Notification綁在一起才能生效。
不過我在這裡的例子因產品需求，全部機型的做法都把Notification綁上。
訊息通知ID
private int MQTT_IM_NOTIFICATION_ID=1007;通知欄Notification的定義
String content = 2 + "個聯絡人發了" + i + "條訊息"; NotificationCompat.Builder builder = new NotificationCompat.Builder(getBaseContext()); builder.setSmallIcon(R.drawable.chat_notify_icon); builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher)); builder.setTicker("收到" + i + "條訊息"); builder.setWhen(System.currentTimeMillis()); Intent intent = new Intent(getBaseContext(), MainActivity.class); intent.setAction(getApplicationContext().getPackageName()); intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); PendingIntent pi = PendingIntent.getActivity(getBaseContext(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); builder.setContentIntent(pi); builder.setContentTitle(getResources().getText(R.string.app_name)); builder.setContentText(content); final Notification n = builder.build(); int defaults = Notification.DEFAULT_LIGHTS; defaults |= Notification.DEFAULT_SOUND; defaults |= Notification.DEFAULT_VIBRATE; n.defaults = defaults; n.flags = Notification.FLAG_SHOW_LIGHTS | Notification.FLAG_AUTO_CANCEL;
廠商
private static String SYSTEM_XIAOMI="XIAOMI"; private static String SYSTEM_SAMSUNG="SAMSUNG"; private static String SYSTEM_HUAWEI_HONOR="HONOR"; private static String SYSTEM_HUAWEI="HUAWEI"; private static String SYSTEM_NOVA="NOVA"; private static String SYSTEM_SONY="SONY"; private static String SYSTEM_VIVO="VIVO"; private static String SYSTEM_OPPO="OPPO"; private static String SYSTEM_LG="LG"; private static String SYSTEM_ZUK="ZUK"; private static String SYSTEM_HTC="HTC";
廠商獲取
OSName=android.os.Build.BRAND.trim().toUpperCase();類名的獲取
主要是得到Activity名字，得到完整的包名、類名
//獲取類名
public static String getLauncherClassName(Context context) {
PackageManager packageManager = context.getPackageManager();
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setPackage(context.getPackageName());
intent.addCategory(Intent.CATEGORY_LAUNCHER);
ResolveInfo info = packageManager.resolveActivity(intent, PackageManager.MATCH_DEFAULT_ONLY);
if (info == null) {
info = packageManager.resolveActivity(intent, 0);
}
return info.activityInfo.name;
}廣播
//廣播
public static boolean canResolveBroadcast(Context context, Intent intent) {
PackageManager packageManager = context.getPackageManager();
List<ResolveInfo> receivers = packageManager.queryBroadcastReceivers(intent, 0);
return receivers != null && receivers.size() > 0;
}小米
特別注意，小米的通知欄提示需要延時操作才會出現角標，但是偶爾還是沒法出現，暫時沒有特別好的解決辦法，不過目前能保證做到較高的成功率。
除了小米以外，其他實現基本沒什麼問題。
//小米
private static void setBadgeOfXiaomi(final Context context,final Notification notification,final int NOTIFI_ID,final int num){
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
try {
Field field = notification.getClass().getDeclaredField("extraNotification");
Object extraNotification = field.get(notification);
Method method = extraNotification.getClass().getDeclaredMethod("setMessageCount", int.class);
method.invoke(extraNotification, num);
} catch (Exception e) {
e.printStackTrace();
Log.e("Xiaomi" + " Badge error", "set Badge failed");
}
// mNotificationManager.notify(0,notification);

其他
做個備案吧，這個真不一定能生效，只能從大多數的做法裡摸規律
//其他
private static void setBadgeOfDefault(Context context,Notification notification,int NOTIFI_ID,int num){

if (canResolveBroadcast(context, intent)) {
context.sendBroadcast(intent);
} else {
Log.e("Default" + " Badge error", "unable to resolve intent: " + intent.toString());
}
NotificationManager notifyMgr = (NotificationManager)(context.getSystemService(NOTIFICATION_SERVICE));
if(num!=0)notifyMgr.notify(NOTIFI_ID, notification);else notifyMgr.cancel(NOTIFI_ID);
}catch (Exception e){
