现在淘宝,京东等App在节假日打开时,都是采用一套节假日的图标,这种不用发版本,又可以随着后台配置动态替换图标固然是很方便,体验很好的事情.

动态替换图标使用的是manifest文件配置入口别名activity-alias：

配置文件：

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.example.mychangeicondome">    <application        android:allowBackup="true"        android:icon="@mipmap/ic_launcher"        android:label="@string/app_name"        android:supportsRtl="true"        android:theme="@style/AppTheme">        <activity            android:icon="@mipmap/ic_launcher"            android:name=".MainActivity"            android:label="@string/app_name">            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>        <activity-alias            android:icon="@mipmap/ic_launcher"            android:name=".test_activity"            android:enabled="false"            android:label="OtherName"            android:targetActivity=".MainActivity">            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity-alias>    </application></manifest>

代码：

public class MainActivity extends AppCompatActivity {    private ComponentName componentName;    private ComponentName componentNameDefault;    private PackageManager packageManager;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        //获取组件别名        componentName = new ComponentName(getBaseContext(), getPackageName() + ".test_activity");        componentNameDefault = new ComponentName(getBaseContext(), getClass().getName());        packageManager = getPackageManager();    }    /**     *     * 切换状态   sijienet.com      * @param view     */    public void mclick(View view){        if (packageManager.getComponentEnabledSetting(componentName)==PackageManager.COMPONENT_ENABLED_STATE_DISABLED || packageManager.getComponentEnabledSetting(componentName) == PackageManager.COMPONENT_ENABLED_STATE_DEFAULT){            packageManager.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED,PackageManager.DONT_KILL_APP);            packageManager.setComponentEnabledSetting(componentNameDefault, PackageManager.COMPONENT_ENABLED_STATE_DISABLED,PackageManager.DONT_KILL_APP);        }else if (packageManager.getComponentEnabledSetting(componentName)==PackageManager.COMPONENT_ENABLED_STATE_ENABLED){            packageManager.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED,PackageManager.DONT_KILL_APP);            packageManager.setComponentEnabledSetting(componentNameDefault, PackageManager.COMPONENT_ENABLED_STATE_ENABLED,PackageManager.DONT_KILL_APP);        }    }}
