Android动态修改应用图标

最近遇到一个功能模块化管理APP, 需要根据不同的业务动态替换应用图标和启动页,搜了大量资料,总结用"别名"activity-alias标签比较实用 简单

直接上代码

布局代码

AndroidManifest.xml 代码

MainActivity 代码

public class Main18Activity extends AppCompatActivity {
    private ComponentName mComponentName1;

    private ComponentName mComponentName2;

    private ComponentName mComponentNameDefault3;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main18);
        String packageName = getPackageName();
        mComponentName1 = new ComponentName(this, packageName + ".MainActivity");
        mComponentName2 = new ComponentName(this, packageName + ".Main2Activity");
        mComponentNameDefault3 = new ComponentName(this, packageName + ".Main3Activity");

    }


    private void enableComponent(ComponentName componentName) {
        getPackageManager().setComponentEnabledSetting(componentName,
                PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
                PackageManager.DONT_KILL_APP);
    }

    private void disableComponent(ComponentName componentName) {
        getPackageManager().setComponentEnabledSetting(componentName,
                PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
                PackageManager.DONT_KILL_APP);
    }

    public void monClick(View view) {
        enableComponent(mComponentName1);
        disableComponent(mComponentName2);
        disableComponent(mComponentNameDefault3);
    }

    public void monClickq(View view) {
        enableComponent(mComponentName1);
        disableComponent(mComponentName2);
        disableComponent(mComponentNameDefault3);
    }

    public void monClickw(View view) {
        disableComponent(mComponentName1);
        enableComponent(mComponentName2);
        disableComponent(mComponentNameDefault3);
    }

    public void monClicke(View view) {
        disableComponent(mComponentName1);
        disableComponent(mComponentName2);
        enableComponent(mComponentNameDefault3);
    }
}

注意: AndroidManifest.xml  android:enabled="false" false表示只会显示一个图标   true表示显示同时存在

现在就可以根绝不同业务活动等需求调用不同的 启动页 APP名字  图标
