android - 隐藏应用程序图标

Question

我正在做一个 Android 应用程序。我想在模拟器中隐藏应用程序图标，我想通过按一些数字(例如 456#)来启动我的应用程序。有办法做到这一点吗？

要以编程方式从启动器中隐藏应用程序图标，您可以执行此操作

    PackageManager packageManager = context.getPackageManager();
    ComponentName componentName = new ComponentName(context,
            LauncherActivity.class);
    packageManager.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
            PackageManager.DONT_KILL_APP);

按数字启动应用程序首先在mainfest文件中添加以下权限

     <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>

然后注册接收者

<receiver android:name=".LaunchAppViaDialReceiver"> 
    <intent-filter> 
    <action android:name="android.intent.action.NEW_OUTGOING_CALL"/>
    </intent-filter> 
</receiver>

然后创建一个接收类

  public class LaunchAppViaDialReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    Bundle bundle = intent.getExtras();
    if (null == bundle)
        return;
    String phoneNubmer = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
             //here change the number to your desired number
    if (phoneNubmer.equals("12345")) {
        setResultData(null);
        Gaurdian.changeStealthMode(context,
                PackageManager.COMPONENT_ENABLED_STATE_ENABLED);
        Intent appIntent = new Intent(context, LauncherActivity.class);
        appIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(appIntent);
    }

}
