TableRow動態添加組件時遇到的問題

1. public class Main extends Activity {
2. ScrollView scroll;
3. TableLayout tl1;
4. public void onCreate(Bundle savedInstanceState){
5. super.onCreate(savedInstanceState);
6. this.setContentView(R.layout.main);
7. tl1 = (TableLayout)this.findViewById(R.id.tl1);
8. TableRow tr = new TableRow(this);
9. tr.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
10. TextView tv = new TextView(this);
11. tv.setText("tex");
12. tv.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
13. tr.addView(tv);
14. tl1.addView(tr,new TableLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
15. }

敲代碼時，如果直接敲LayoutParams這個類的話，默認導入的包是Android.view.ViewGroup.LayoutParams;

如果導入了這個包，實際上在Activity中是無法正常顯示要加入的View組件的

真正要導入的包是android.widget.TableRow.LayoutParams;不過這個包在Eclipse中並沒有提示出來，裝了ADT15依然沒有提示。
