三星的 TWLauncher 允许应用程序在应用程序图标上创建徽章计数。
这是完全无证的！任何地方都没有提到它，只有少数应用程序在使用它（例如 Facebook、eBay）。
您如何使用此功能为您的应用程序图标添加计数？
这是非常特定于三星设备的。我不是在问一般的Android。我只是在问三星的 Touchwhiz 界面，它目前允许标记。安卓没有。

首先，您需要将以下权限添加到您的 AndroidManifest.xml 文件中。
<uses-permission android:name="com.sec.android.provider.badge.permission.READ" />
<uses-permission android:name="com.sec.android.provider.badge.permission.WRITE" />
列结构如下：
(integer) _id, (text) package, (text) class, (integer) badgecount, (blob) icon, (???) extraData
为了从 BadgeProvider 查询所有结果，请执行以下操作：
// This is the content uri for the BadgeProvider
Uri uri = Uri.parse("content://com.sec.badge/apps");
Cursor c = getContentResolver().query(uri, null, null, null, null);
// This indicates the provider doesn't exist and you probably aren't running
// on a Samsung phone running TWLauncher. This has to be outside of try/finally block
if (c == null) {
return;
}
try {
if (!c.moveToFirst()) {
// No results. Nothing to query
return;
}
c.moveToPosition(-1);
while (c.moveToNext()) {
String pkg = c.getString(1);
String clazz = c.getString(2);
int badgeCount = c.getInt(3);
Log.d("BadgeTest", "package: " + pkg + ", class: " + clazz + ", count: " + String.valueOf(cnt));
}
} finally {
c.close();
}
为了将徽章计数添加到您的应用程序图标
ContentValues cv = new ContentValues();
cv.put("package", getPackageName());
// Name of your activity declared in the manifest as android.intent.action.MAIN.
// Must be fully qualified name as shown below
cv.put("class", "com.example.badge.activity.Test");
cv.put("badgecount", 1); // integer count you want to display
// Execute insert
getContentResolver().insert(Uri.parse("content://com.sec.badge/apps"), cv);
如果您想清除图标上的徽章计数
ContentValues cv = new ContentValues();
cv.put("badgecount", 0);
getContentResolver().update(Uri.parse("content://com.sec.badge/apps"), cv, "package=?", new String[] {getPackageName()});

我创建了一个开源项目，您可以将其作为库导入以协助完成此操作。它已作为 Apache 获得许可，因此请随意使用它。

将这些权限添加到清单
<!--for android badge-->
<uses-permission android:name="com.android.launcher.permission.READ_SETTINGS"/>
<uses-permission android:name="com.android.launcher.permission.WRITE_SETTINGS"/>
<!--for Samsung badge-->
<uses-permission android:name="com.sec.android.provider.badge.permission.READ"/>
<uses-permission android:name="com.sec.android.provider.badge.permission.WRITE"/>
<!--for htc badge-->
<uses-permission android:name="com.htc.launcher.permission.READ_SETTINGS"/>
<uses-permission android:name="com.htc.launcher.permission.UPDATE_SHORTCUT"/>
<!--for sony badge-->
<uses-permission android:name="com.sonyericsson.home.permission.BROADCAST_BADGE"/>
<!--for apex badge-->
<uses-permission android:name="com.anddoes.launcher.permission.UPDATE_COUNT"/>
将这些包名称添加到您的课程中：
final String HOME_PACKAGE_SONY = "com.sonyericsson.home";
final String HOME_PACKAGE_SAMSUNG = "com.sec.android.app.launcher";
final String HOME_PACKAGE_LG = "com.lge.launcher2";
final String HOME_PACKAGE_HTC = "com.htc.launcher";
final String HOME_PACKAGE_ANDROID = "com.android.launcher";
final String HOME_PACKAGE_APEX = "com.anddoes.launcher";
final String HOME_PACKAGE_ADW = "org.adw.launcher";
final String HOME_PACKAGE_ADW_EX = "org.adwfreak.launcher";
final String HOME_PACKAGE_NOVA = "com.teslacoilsw.launcher";
用来 ：
// just put your pachage and main activity class path
String classPath = "ir.faasaa.resa.MainActivity";
ContentValues cv = new ContentValues();
cv.put("package", context.getPackageName());
cv.put("class", classPath);
cv.put("badgecount", count);
context.getContentResolver().insert(Uri.parse(HOME_PACKAGE_SAMSUNG), cv);

在 android 中，我们没有 iOS 那样的徽章样式方法，但一些制造商支持在应用程序图标上显示徽章。
支持索尼和HTC。
Sony 和 HTC 支持在应用图标上添加徽章。
对于索尼
<uses-permission android:name="com.sonyericsson.home.permission.BROADCAST_BADGE" />
Intent intent= new Intent("com.sonyericsson.home.action.UPDATE_BADGE");
intent.putExtra("com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME", Class Name);
intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", true);
intent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE",number);
intent.putExtra("com.sonyericsson.home.intent.extra.badge.PACKAGE_NAME", packageName);
sendBroadcast(intent);
宏达电：
<uses-permission android:name="com.htc.launcher.permission.READ_SETTINGS" />
<uses-permission android:name="com.htc.launcher.permission.UPDATE_SHORTCUT" />
Intent updateIntent = new Intent("com.htc.launcher.action.UPDATE_SHORTCUT");
updateIntent.putExtra("packagename", packageName);
updateIntent.putExtra("count", number);
this.sendBroadcast(updateIntent);
Intent setNotificationIntent = new Intent("com.htc.launcher.action.SET_NOTIFICATION");
ComponentName localComponentName = new ComponentName(packageName, className);
setNotificationIntent.putExtra("com.htc.launcher.extra.COMPONENT", localComponentName.flattenToShortString());
setNotificationIntent.putExtra("com.htc.launcher.extra.COUNT", number);
this.sendBroadcast(setNotificationIntent);

我将此类用于三星和索尼设备（也可使用https://gist.github.com/Tadas44/cdae2f5995f21bf1c27f）。不要忘记添加<uses-permission android:name="com.sonyericsson.home.permission.BROADCAST_BADGE" />到 AndroidManifest.xml
public class BadgeUtils {
public static void setBadge(Context context, int count) {
setBadgeSamsung(context, count);
setBadgeSony(context, count);
}
public static void clearBadge(Context context) {
setBadgeSamsung(context, 0);
clearBadgeSony(context);
}
private static void setBadgeSamsung(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);
}
private static void setBadgeSony(Context context, int count) {
String launcherClassName = getLauncherClassName(context);
if (launcherClassName == null) {
return;
}
Intent intent = new Intent();
intent.setAction("com.sonyericsson.home.action.UPDATE_BADGE");
intent.putExtra("com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME", launcherClassName);
intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", true);
intent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE", String.valueOf(count));
intent.putExtra("com.sonyericsson.home.intent.extra.badge.PACKAGE_NAME", context.getPackageName());
context.sendBroadcast(intent);
}
private static void clearBadgeSony(Context context) {
String launcherClassName = getLauncherClassName(context);
if (launcherClassName == null) {
return;
}
Intent intent = new Intent();
intent.setAction("com.sonyericsson.home.action.UPDATE_BADGE");
intent.putExtra("com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME", launcherClassName);
intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", false);
intent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE", String.valueOf(0));
intent.putExtra("com.sonyericsson.home.intent.extra.badge.PACKAGE_NAME", context.getPackageName());
context.sendBroadcast(intent);
}
private 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;
}
}

还有另一种工具可用于 Xperia 设备
Intent intent = new Intent();
intent.setAction("com.sonyericsson.home.action.UPDATE_BADGE");
intent.putExtra("com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME", "com.yourdomain.yourapp.MainActivity");
intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", true);
intent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE", "99");
intent.putExtra("com.sonyericsson.home.intent.extra.badge.PACKAGE_NAME", "com.yourdomain.yourapp");
sendBroadcast(intent);
intent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE", "10");

对于 Android 8.0 Oreo 用户-
对于那些在显示带有 Oreo 的三星 S8、S9 或 Pixel设备的徽章计数时遇到问题的人，请注意ShortcutBadger库不支持在问题API>26中Samsung报告的此处。如果是这样，您必须先检查它-isBadgeCounterSupported
public boolean isBadgeCounterSupported() {
// Workaround for bug in ShortcutBadger in version 1.1.19, registered as
// https://github.com/leolin310148/ShortcutBadger/issues/266
if (Build.MANUFACTURER.equalsIgnoreCase("Samsung") && Build.VERSION.SDK_INT >= 26) {
Log.d("LOG_TAG", "Launcher icon badge (ShortcutBadger) is not supported on Samsung devices running Android 8 (or newer).");
return false;
}
return ShortcutBadger.isBadgeCounterSupported(context);
}
唯一的方法是从Notification应用Badges。至于从通知中应用徽章，请参阅Android 文档，并注意“设置自定义通知计数”部分。
Notification notification = new NotificationCompat.Builder(MainActivity.this, "my_channel_01")
.setContentTitle("New Messages")
.setContentText("You've received 3 new messages.")
.setSmallIcon(R.drawable.ic_notify_status)
.setNumber(messageCount) //this badge count
.build();
有关 Android 8.0 中通知的更多信息，请参阅此答案。
