This TableLayout layout or its parent is useless

场景：初学者有关问题 This TableRow layout or its TableLayout parent is useless

菜鸟问题 This TableRow layout or its TableLayout parent is useless
 界面设置中 TableRow提示 This TableRow layout or its TableLayout parent is useless，搞不清那里出了毛病，程序也运行不起来，感觉是界面的问题，不知道界面能调试吗？？


界面代码如下。
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@id/layout_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/main_background"
    android:orientation="vertical" >

    <RelativeLayout
        android:id="@id/titlebar1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/bar" >

        <Textview
            android:id="@id/titlebar1_title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="10.0dip"
            android:layout_marginTop="7.0dip"
            android:text="@string/titlebar1_title"
            android:textSize="23.0sp" />
    </RelativeLayout>

    <TableLayout
        android:layout_width="match_parent"

        <TableRow>

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:gravity="center_vertical"
                android:text="@string/titlebar1_label"
                android:textColor="@drawable/white"
                android:textSize="20sp"
                android:textStyle="bold" />

            <EditText
                android:id="@id/edit1"
                android:layout_width="200dp"
                android:layout_height="wrap_content"
                android:inputType="text" />
        </TableRow>
    </TableLayout>

    <ListView
        android:id="@id/listView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >
    </ListView>

</LinearLayout>

java文件
public class OreActivity extends Activity
{
        @Override
        protected void onCreate(Bundle savedInstanceState)
        {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.activity_ore);                
        }
｝

android:stretchColumns="1"
