L003) TableLayoutで基本的なボタンを複数作る

目的

TableLayoutを使う
Button[] を12個配置する

point

TableLayoutのインスタンスに行インスタンス TableRowを追加
行インスタンスにボタンを配置

TableLayout table = new TableLayout(context);
//forループ
TableRow row = new TableRow(context);  //TableRowインスタンス生成
row.addView(Buttonインスタンス)
table.addView(row)　//TableRowインスタンスをTableLayoutインスタンスに配置
