本文在上一篇初步介绍TableLayout常用属性的基础上,将进一步介绍如何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:
1
2
3
4
5
6
7
8
9
10
11
12

<? 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代码部分如下:

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:
