Android入门第五篇之TableLayout (二) .

上一篇文章，主要将如何UI设计器设计TableLayout + TableRow，由于实际应用中，经常需要在代码里往TableLayout添加数据(9宫图也可以用TableLayout做出来 )，本文就是介绍这方面的简单使用方法。

main.xml的代码如下，用到TableLayout的ID为TableLayout01：

[xhtml] view plaincopyprint?

1. <?xmlversion="1.0"encoding="utf-8"?>
2. <LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"
3. android:orientation="vertical"
4. android:layout_width="fill_parent"
5. android:layout_height="fill_parent"
6. >
7. <TableLayout
8. android:id="@+id/TableLayout01"
9. android:layout_width="fill_parent"
10. android:layout_height="wrap_content">
11. </TableLayout>
12. </LinearLayout>

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TableLayout android:id="@+id/TableLayout01" android:layout_width="fill_parent" android:layout_height="wrap_content"> </TableLayout> </LinearLayout>

JAVA代码如下：

[java] view plaincopyprint?

1. packagecom.LayoutDemo;
2. importcom.LayoutDemo.R;
3. importandroid.app.Activity;
4. importandroid.os.Bundle;
5. importandroid.view.ViewGroup;
6. importandroid.widget.TableLayout;
7. importandroid.widget.TableRow;
8. importandroid.widget.TextView;
9. publicclassLayoutDemoextendsActivity{
10. /**Calledwhentheactivityisfirstcreated.*/
11. privatefinalintWC=ViewGroup.LayoutParams.WRAP_CONTENT;
12. privatefinalintFP=ViewGroup.LayoutParams.FILL_PARENT;
14. @Override
15. publicvoidonCreate(BundlesavedInstanceState){
16. super.onCreate(savedInstanceState);
17. setContentView(R.layout.main);
18. //新建TableLayout01的实例
19. TableLayouttableLayout=(TableLayout)findViewById(R.id.TableLayout01);
20. //全部列自动填充空白处
21. tableLayout.setStretchAllColumns(true);
22. //生成10行，8列的表格
23. for(introw=0;row<10;row++)
24. {
25. TableRowtableRow=newTableRow(this);
26. for(intcol=0;col<8;col++)
27. {
28. //tv用于显示
29. TextViewtv=newTextView(this);
30. tv.setText("("+col+","+row+")");
31. tableRow.addView(tv);
32. }
33. //新建的TableRow添加到TableLayout
34. tableLayout.addView(tableRow,newTableLayout.LayoutParams(FP,WC));
35. }
36. }
37. }

package com.LayoutDemo; import com.LayoutDemo.R; import android.app.Activity; import android.os.Bundle; import android.view.ViewGroup; import android.widget.TableLayout; import android.widget.TableRow; import android.widget.TextView; public class LayoutDemo extends Activity { /** Called when the activity is first created. */ private final int WC = ViewGroup.LayoutParams.WRAP_CONTENT; private final int FP = ViewGroup.LayoutParams.FILL_PARENT; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); //新建TableLayout01的实例 TableLayout tableLayout = (TableLayout)findViewById(R.id.TableLayout01); //全部列自动填充空白处 tableLayout.setStretchAllColumns(true); //生成10行，8列的表格 for(int row=0;row<10;row++) { TableRow tableRow=new TableRow(this); for(int col=0;col<8;col++) { //tv用于显示 TextView tv=new TextView(this); tv.setText("("+col+","+row+")"); tableRow.addView(tv); } //新建的TableRow添加到TableLayout tableLayout.addView(tableRow, new TableLayout.LayoutParams(FP, WC)); } } }

结果如下图：
