在android4.0以上版本中，新增加了GridLayout网格布局，请参考[Android 4.0开发之GridLayOut布局实践][Android 4.0_GridLayOut]和[浅谈android4.0开发之GridLayout布局][android4.0_GridLayout]

<?xml version="1.0" encoding="utf-8"?> 
    <GridLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:columnCount="4"//该网格布局有4列
        android:orientation="horizontal" > //水平依次排列，排满4列后，换行排列
        <Button
            android:layout_column="3"//该按钮定位在第4列上（从0开始计算）
            android:text="/" /> 
        <Button android:text="1" /> 
        <Button android:text="2" /> 
        <Button android:text="3" /> 
        <Button android:text="*" /> 
        <Button android:text="4" /> 
        <Button android:text="5" /> 
        <Button android:text="6" /> 
        <Button android:text="-" /> 
        <Button android:text="7" /> 
        <Button android:text="8" /> 
        <Button android:text="9" /> 
        <Button
            android:layout_rowSpan="3"//该按钮在一列上占3行
            android:layout_gravity="fill"//该按钮填充占满一列3行
            android:text="+" /> 
        <Button
            android:layout_columnSpan="2"//该按钮在一行上占2列
            android:layout_gravity="fill"
            android:text="0" /> 
        <Button android:text="00" /> 
        <Button
            android:layout_columnSpan="3"
            android:layout_gravity="fill"
            android:text="=" /> 
    </GridLayout>

在开发中有些时候完成某些功能，不得不在java代码中实现GridLayout

java代码：

GridLayout.LayoutParams gllpTv;
    gllpTv = new GridLayout.LayoutParams();
    gllpTv.columnSpec = GridLayout.spec(0, 5);//相当于android:layout_columnSpan="5" spec(start,size)参数为起始位置，占几列
    TextView timeText = new TextView(this);
    timeText.setText("********");
    timeText.setTextSize(26);
    timeText.setPadding(10, 50, 0, 5);
    gridlayout.addView(timeText, gllpTv);//把控件和布局参数添加到GridLayout

类似Gridview的使用

for (int j = 0; j < playRecordList.size(); j++) {
            View v = inflater.inflate(R.layout.gridview_playrecord_item_layout, null);
    	ImageView playrecord_img = (ImageView) v.findViewById(R.id.play_record_img);
            TextView playrecord_name = (TextView) v.findViewById(R.id.play_record_name);
    	fb.display(playrecord_img, playRecordList.get(j).getVideoImgUrl());
    	playrecord_name.setText(playRecordList.get(j).getVideoName());
    	playrecord_img.setFocusable(true);
    	playrecord_img.setClickable(true);
    	playrecord_img.setTag(playRecordList.get(j));
    	playrecord_img.setOnClickListener(myCliclListener);
    	gridlayout.addView(v);
    }

还在继续更新中！！！
