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：

view plaincopy to clipboardprint?

JAVA代码如下：

view plaincopy to clipboardprint?

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：
