Android动态修改应用图标最佳实践 - 简书

AndroidManifest.xml 中

<activity-alias
    android:name="包名.ui.mine.SecondActivityAlias"
    android:label="快捷入口"
    android:icon="@mipmap/collection_one"
    android:targetActivity="包名.ui.splash.SplashActivityZs">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity-alias>
<activity-alias
    android:name="包名.ui.mine.SecondActivityAlias2"
    android:label="快捷入口2"
    android:icon="@mipmap/collection_two"
    android:targetActivity="包名.ui.splash.SplashActivityZs">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity-alias>

//注意：SecondActivityAlias  SecondActivityAlias2 需要创建相应的activity  否则下面ComponentName 方法会报 找不到文件问题

/**
 * 下面逻辑是   将快捷入口2禁用  快捷入口开启 
 */

    val context: Application = TTWMyApplication.myApplication!!
    val aliasComponentName = ComponentName(

    val aliasComponentName2 = ComponentName(

    )
    val iPackageManager: PackageManager = context.getPackageManager()
