The main content of this article is to explain "Android how to achieve app local switch between logo and name", interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Next let the editor to take you to learn "Android how to achieve app local switch between logo and name" bar!

First of all, in the AndroidManifest.xml file of app, configure the logo and app names to be replaced

Eg: the following is configured with a default set of two sets of icon and names for switching

Android:enabled: when set to "true", the Activity of the current alias is enabled, and the current icon and the current application name are enabled: when set to "false", the Activity of the current alias is stopped

Android:icon: the application icon for the current alias

Android:label: the application name of the current alias

Android:name: alias. Naming rules are the same as Actively.

Android:targetActivity: the name of the actual Activity called by alias

Then there is code switching: an introduction to related methods.

Toggle the enable / stop state on any component defined in the manifest file through PackageManager.

PackageManager.setComponentEnabledSetting

Sets the enabling settings for package components (activities, receivers, services, providers). This setting overrides any enabled state set by the component in its inventory.

Parameters:

Components to be enabled by componentName-

The newly enabled state of the newState- component.

Optional behavior flags for flags-

Package com.cgg.change_iconimport android.content.ComponentNameimport android.content.Contextimport android.content.pm.PackageManagerimport androidx.appcompat.app.AppCompatActivityimport android.os.Bundleimport android.widget.Buttonimport android.widget.ImageViewimport android.widget.RadioGroupimport androidx.annotation.StringDefclass MainActivity: AppCompatActivity () {val APP_D = "com.cgg.change_icon.DefaultAliasActivity" val APP_1 = "com.cgg.change_icon.Alias1Activity" val APP_2 = "com.cgg.change_icon.Alias2Activity" Private var mPackageManager: PackageManager? = null override fun onCreate (savedInstanceState: Bundle?) {super.onCreate (savedInstanceState) setContentView (R.layout.activity_main) mPackageManager = applicationContext.packageManager findViewById (R.id.iv_0). SetOnClickListener {ShowComponent (APP_D)} findViewById (R.id.iv_1). SetOnClickListener {ShowComponent (APP_1)} FindViewById (R.id.iv_2). SetOnClickListener {ShowComponent (APP_2)}} private fun ShowComponent (app: String) {packageManager.run {setComponentEnabledSetting (componentName) PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP) setComponentEnabledSetting (ComponentName (baseContext, app), PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP)}

Paste the layout, too.

Now that the function is over, let's talk about the defects.

When the replacement icon needs to be packaged, it is pre-embedded in the code. After icon switch is the same as the flicker, if you update the package without activity-alias, it will cause the risk that APP will never find it from the desktop again.
