如何在我的android應用程序中的啓動器圖標上顯示徽章計數？

Question

我曾嘗試下面的意圖方法，但它不能正常工作，

Intent intent = new Intent("android.intent.action.BADGE_COUNT_UPDATE"); 
    intent.putExtra("badge_count", 3); 
    intent.putExtra("badge_count_package_name", getApplicationContext().getPackageName()); 
    intent.putExtra("badge_count_class_name", MainActivity.class.getName()); 
    getApplicationContext().sendBroadcast(intent); 

Answer 1

有做的不標準的方式。但是你可以參考第三方庫，但它只支持很少的設備。 您可以檢查以下庫： https://github.com/leolin310148/ShortcutBadger

它可以在三星的TouchWiz發射

public static void setBadge(Context context, int count) { 
    String launcherClassName = getLauncherClassName(context); 
    if (launcherClassName == null) { 
     return; 
    } 
    Intent intent = new Intent("android.intent.action.BADGE_COUNT_UPDATE"); 
    intent.putExtra("badge_count", count); 
    intent.putExtra("badge_count_package_name", context.getPackageName()); 
    intent.putExtra("badge_count_class_name", launcherClassName); 
    context.sendBroadcast(intent); 
} 

public static String getLauncherClassName(Context context) { 

    PackageManager pm = context.getPackageManager(); 

    Intent intent = new Intent(Intent.ACTION_MAIN); 
    intent.addCategory(Intent.CATEGORY_LAUNCHER); 

    List<ResolveInfo> resolveInfos = pm.queryIntentActivities(intent, 0); 
    for (ResolveInfo resolveInfo : resolveInfos) { 
     String pkgName = resolveInfo.activityInfo.applicationInfo.packageName; 
     if (pkgName.equalsIgnoreCase(context.getPackageName())) { 
      String className = resolveInfo.activityInfo.name; 
      return className; 
     } 
    } 
    return null; 
}
