android – 在合并中膨胀

嗨,我正试图用< merge>来扩充我的布局这里的标签是我的main.xml：

<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://scheR_22_11845@as.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <com.osmgames.kartuves.LinesLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:id="@+id/lines" />

</merge>

这是我的LinesLayout.java：

public class LinesLayout extends FrameLayout {

    public LinesLayout(Context context,AttributeSet attrs) {
        super(context,attrs);
    }
    @Override
    protected void onLayout(Boolean changed,int l,int t,int r,int b) {
        super.onLayout(changed,l,t,r,b);
    }
    @Override
    public Boolean onInterceptTouchEvent(MotionEvent event) {
        super.onInterceptTouchEvent(event);
        return false;
    }
}

而我的main.java：

public class main extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceStatE) {
        super.onCreate(savedInstanceStatE);
        setContentView(R.layout.main);
    }}

所以我想将下面的XML扩展到main.xml.我怎样才能做到这一点？

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://scheR_22_11845@as.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent">

    <ImageView   
         android:layout_width="40dp" 
         android:layout_height="40dp"
         android:layout_gravity="center" 
         android:layout_marginTop="75dp" 
         android:layout_marginRight="40dp"
         android:src="@drawable/line" />

    <ImageView   
         android:layout_width="40dp" 
         android:layout_height="40dp"
         android:layout_gravity="center" 
         android:layout_marginTop="75dp" 
         android:src="@drawable/line" />

    <ImageView   
         android:layout_width="40dp" 
         android:layout_height="40dp"
         android:layout_gravity="center" 
         android:layout_marginTop="75dp" 
         android:layout_marginLeft="40dp"
         android:src="@drawable/line"  />
</FrameLayout>

这是我得到的日志：

InGame.java:59是：

58 FrameLayout item = (FrameLayout)findViewById(R.id.lines);
59 View child = getLayoutInflater().inflate(R.layout.letters3,null);
60 item.addView(child);
