[转] Android 在程序中如何动态的修改程序图标

<http://stackoverflow.com/a/41501402>

亲测可以!
测试机器环境如下:
Meizu Mx4 - Android 5.1 - Flyme 5.1.11.1A

First prepare your new app icons for each resolution and put them into the corresponding mipmap folders.

Then use activity-alias, for example, in your AndroidManifest.xml, edit this:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<activity-alias
android:name=".MainAliasActivity"
android:enabled="false"
android:icon="@mipmap/ic_launcher_fight"
android:label="Main Alias Activity"
android:targetActivity=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity-alias>

Add the following code when you want to change your app icon

1
2
3
4
5
6
7
8
9
PackageManager pm = getPackageManager();
pm.setComponentEnabledSetting(
getComponentName(),
PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
PackageManager.DONT_KILL_APP);
pm.setComponentEnabledSetting(
new ComponentName(this, "YOUR PACKAGE.MainAliasActivity"),
PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
PackageManager.DONT_KILL_APP);

To reset the app icon you can use the same way.
