android - 可以在服务中扩展 XML 布局吗？ (安卓)

Question

我想在服务中扩展 xml 布局。你怎么做到这一点？我尝试使用充气机和窗口管理器，但我认为它不起作用。这有什么战术吗？谢谢。

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent"
android:orientation="vertical"
android:id="@+id/main"
>
    <LinearLayout
        android:id="@+id/top"
        android:layout_height="match_parent"
        android:layout_width="match_parent"
        android:layout_weight="1"
        android:orientation="horizontal"
        >


    <FrameLayout
        android:id="@+id/topLeft"
        android:layout_width="match_parent"
        android:layout_height="match_parent"

        android:tag="topLeft"
        android:layout_weight="1.0"
        android:background="#ff3d38"></FrameLayout>


    <FrameLayout
        android:id="@+id/topRight"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:tag="topRight"

    android:layout_weight="1.0"
        android:background="#fff839"></FrameLayout>

    </LinearLayout>

<LinearLayout
    android:layout_height="match_parent"
    android:layout_width="match_parent"
    android:layout_weight="1"
    android:orientation="horizontal"
    android:id="@+id/bottom"
    >

<FrameLayout
        android:id="@+id/bottomLeft"
        android:layout_width="match_parent"
        android:layout_height="match_parent"

        android:layout_weight="1.0"
        android:background="#1e22ff">

    </FrameLayout>

    <FrameLayout
        android:id="@+id/bottomRight"
        android:layout_width="match_parent"
        android:layout_height="match_parent"

        android:layout_weight="1.0"
        android:background="#32ff1f"></FrameLayout>

这是我要显示的 xml 的服务代码。

  // wm.addView(mainButton, params);
     wm.addView(mView,params);

   Log.d("tok", "add mview");


   }

可以在服务上放一个图形代码是这样的:

li = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
        wm = (WindowManager) getSystemService(WINDOW_SERVICE);

        WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                //WindowManager.LayoutParams.TYPE_INPUT_METHOD |
                WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,// | WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
                WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH | WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
                PixelFormat.TRANSLUCENT);

        params.gravity = Gravity.RIGHT | Gravity.TOP;
        myview = li.inflate(R.layout.traslucent, null);     

        wm.addView(myview, params);
