Android上GridLayout和java上的感覺差不多，但是在添加布局內部新增控制元件就不是那麼容易了。

grid = (GridLayout)findViewById(R.id.grid); //獲取GridLayout控制元件
			int count=1;
		for(int i=0;i<6;i++)
			for(int j=0;j<5;j++) {
				System.out.println("count:"+count);
				Button btn = new Button(this);
				btn.setWidth(40);           
				btn.setText(String.valueOf(count));
				count++;
				GridLayout.Spec rowSpec = GridLayout.spec(i);     //設定它的行和列
				GridLayout.Spec columnSpec=GridLayout.spec(j);
				GridLayout.LayoutParams params=new GridLayout.LayoutParams(rowSpec,columnSpec);
				params.setGravity(Gravity.LEFT);
				grid.addView(btn,params);
			}
