代碼部分：

src  GridLayoutTest.java

package cn.com.gridlayouttest;


import android.app.Activity;
import android.os.Bundle;
import android.view.Gravity;
import android.widget.Button;
import android.widget.GridLayout;

public class GridLayoutTest extends Activity {

	GridLayout gridLayout;
	String[] chars=new String[]
			{
				"7","8","9","/",
				"4","5","6","*",
				"1","2","3","-",
				".","0","=","+"
			};
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		gridLayout=(GridLayout) findViewById(R.id.root);
		for(int i=0;i<chars.length;i++){
			Button bn=new Button(this);
			bn.setText(chars[i]);
			bn.setTextSize(40);
			GridLayout.Spec rowSpec=GridLayout.spec(i/4+2);
			GridLayout.Spec columnSpec=GridLayout.spec(i%4);
			GridLayout.LayoutParams params=new GridLayout.LayoutParams(rowSpec,columnSpec);
			//指定該組建佔滿父容器
			params.setGravity(Gravity.FILL);
			gridLayout.addView(bn,params);
		}
	}
