在 TableLayout 中以编程方式分配行中的列权重

Question

我只想在表中定义一行。对于这一行，我想添加 3 列，其宽度如下：

textView1 ：应该与其内容一样宽

viewDivider：应该是 2px 宽

TextView2：应该占据 tablerow 的剩余区域。

但是，我无法以编程方式实现上述布局。这是代码：

public class Copy_2_of_Test extends Activity {
 TableLayout tableLayout = null;
 TextView textView1 = null;
 TextView textView2 = null;
 View viewDivider = null;

 TableLayout tab = null;

      @Override
      public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView (R.layout.test);
        tableLayout = (TableLayout)this.findViewById(R.id.mainTable);
        addViews();
      }

      private void addViews() {
       // table row with layout params of type TableLayout.LayoutParams
       TableRow tr = new TableRow(this);
        tr.setLayoutParams(new TableLayout.LayoutParams(
                            LayoutParams.FILL_PARENT, 
                            LayoutParams.FILL_PARENT));

       // Textview 1 with layout params of type TableRow.LayoutParams
        textView1 = new TextView(this);
        textView1.setText("Value1");
        textView1.setTextColor(Color.BLACK);
        textView1.setBackgroundColor(Color.YELLOW);
        textView1.setLayoutParams(new TableRow.LayoutParams(
                            LayoutParams.WRAP_CONTENT,
                            LayoutParams.FILL_PARENT));
        tr.addView(textView1);

        viewDivider = new View (this);
        viewDivider.setLayoutParams(new TableRow.LayoutParams(
                            2,
                            LayoutParams.FILL_PARENT));
        viewDivider.setBackgroundColor(Color.MAGENTA);
        tr.addView(viewDivider);


       // Textview 2 with layout params of type TableRow.LayoutParams
        textView2 = new TextView(this);
        textView2.setText("Value2 Value2  Value2  Value2 ");
        textView2.setTextColor(Color.BLACK);
        textView2.setBackgroundColor(Color.YELLOW);
        textView2.setLayoutParams(new TableRow.LayoutParams(
                            LayoutParams.WRAP_CONTENT,
                            LayoutParams.FILL_PARENT));
        tr.addView(textView2);

        // Add row to TableLayout. 
        tableLayout.addView(tr,new TableLayout.LayoutParams(
             LayoutParams.FILL_PARENT,
             LayoutParams.FILL_PARENT));
   }

    }

这是 test.xml：

     <?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:stretchColumns="*"
       android:background="@color/black"
       android:id="@+id/mainTable"> 

     </TableLayout>

我面临上述布局的以下问题：

1）textView1 占用的宽度大于其内容。

2）viewDivider占用了很多宽度并且不限制为2px

感谢您的帮助。

尝试使用 setWidth() 方法设置宽度。
