三星TWLauncher允许应用在应用程序图标创建徽章计数。

Samsung's TWLauncher allows apps to create badge counts on app icons.

这是完全没有证件任何地方，只有极少数的应用程序都采用这种（脸谱，eBay的命名一对夫妇）。

This is completely undocumented ANYWHERE and only a handful of apps are using this (Facebook, eBay to name a couple).

你如何使用这个功能来计数添加到您的应用程序图标？

How do you use this functionality to add a count to your application icon?

推荐答案

首先，您需要在以下权限添加到您的Andr​​oidManifest.xml文件。

First you'll need to add the following permissions to your AndroidManifest.xml file.

<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

为了查询所有结果从BadgeProvider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();
}

为了添加徽章数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);

如果你想清除你的图标徽章计数

ContentValues cv = new ContentValues();
cv.put("badgecount", 0);
getContentResolver().update(Uri.parse("content://com.sec.badge/apps"), cv, "package=?", new String[] {getPackageName()});  

新 我创建了可以导入作为一个库，以协助这方面的一个开源项目。它的行货与Apache可以随意使用它，请你。

NEW I have created an open source project that you can import as a library to assist with this. It's licensed as Apache so feel free to use it as you please.
