我试图填充一个tablelayout与单元格和行拉伸填充整个屏幕.像这样:

在Eclipse的Graphical Layout窗口中设计的这个布局给出了我想要的东西(android:layout_weight解决了垂直拉伸):

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_gravity="center"
    android:stretchColumns="*" >

    <TableRow
        android:id="@+id/tableRow1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center" android:layout_weight="1">

        <ImageView
            android:id="@+id/imageView1"
            android:layout_gravity="center"
            android:src="@drawable/add" />
        <ImageView
            android:id="@+id/imageView2"
            android:layout_gravity="center"
            android:src="@drawable/bound" />
        <ImageView
            android:id="@+id/imageView3"
            android:layout_gravity="center"
            android:src="@drawable/cod" />
    </TableRow>

    <TableRow
        android:id="@+id/tableRow2"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_weight="1" >

    <ImageView
        android:id="@+id/imageView4"
        android:layout_gravity="center"
        android:src="@drawable/delete" />
    <ImageView
        android:id="@+id/imageView5"
        android:layout_gravity="center"
        android:src="@drawable/delete2" />
    <ImageView
        android:id="@+id/imageView6"
        android:layout_gravity="center"
        android:src="@drawable/floppy" />
    </TableRow>
</TableLayout>

我试图在代码中创建相同的外观但到目前为止失败.这是我的活动的创建:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.tablelo);

    TableLayout tl = (TableLayout) findViewById(R.id.table);
    Log.d(TAG, "Width :" + tl.getWidth());
    for (int …
