Android Badger Icon 提示 通知 數字

icon上的數字提示通知，Android沒有內建的，所以使用第三方套件ShortcutBadger

使用IDE: Android Studio
1.建立新方案後，在build.gradle(Module:app)檔案裡的dependencies位置裡面加上 compile 'me.leolin:ShortcutBadger:1.1.3@aar' 下載該套件

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'me.leolin:ShortcutBadger:1.1.3@aar'
}
