stretchMode属性值的作用是设置GridView中的条目以什么缩放模式去填充剩余空间。参数stretchMode 可选值为:none,spacingWidth,columnWidth, spacingWidthUniform

注意:spaceWidth和spacingWidthUniform是有差别的，下面通过一个例子说明一下,本人手机屏幕4.7英寸,分辨率为1280×720

1.建立一个Android项目

界面布局文件activity_main.xml如下:

字符串文件strings.xml如下:

     
         
      
       gridviewtest
          
      
       F00
          
      
       0F0
          
      
       00F
          
      
       FF0
          
      
       F0F
          
      
       0FF
          
      
       07F
          
      
       F07
          
      
       70F
      
     

颜色文件colors.xml如下:

     
         
      
       #F00
          
      
       #0F0
          
      
       #00F
          
      
       #FF0
          
      
       #F0F
          
      
       #0FF
          
      
       #07F
          
      
       #F07
          
      
       #70F
      
     

2.编写代码，如下:

public class MainActivity extends Activity {        int []colors=new int[]    {        R.color.c1,R.color.c2,R.color.c3,        R.color.c4,R.color.c5,R.color.c6,        R.color.c7,R.color.c8,R.color.c9    };    int []texts=new int[]    {        R.string.c1,R.string.c2,R.string.c3,        R.string.c4,R.string.c5,R.string.c6,        R.string.c7,R.string.c8,R.string.c9    };    Button button1;    GridView gridview1;        protected void onCreate(Bundle savedInstanceState)    {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);         button1=(Button)findViewById(R.id.button1);        gridview1=(GridView)findViewById(R.id.gridview1);                 button1.setOnClickListener(new OnClickListener()        {             @Override              public void  onClick(View v)             {                 int width=gridview1.getColumnWidth();                 int widthSpace=gridview1.getHorizontalSpacing();                            Toast.makeText(MainActivity.this, "columnWidth:"+width+",widthSpace:"+widthSpace, Toast.LENGTH_LONG).show();             }         });                 final BaseAdapter baseAdapter=new BaseAdapter()        {             @Override            public int getCount() {                return texts.length;            }             @Override            public Object getItem(int arg0) {                return getResources().getString(texts[arg0]);            }             @Override            public long getItemId(int arg0) {                return arg0;            }             @Override            public View getView(int position, View view, ViewGroup viewGroup) {                                 TextView textView=new TextView(MainActivity.this);                textView.setText(getItem(position).toString());                textView.setTextSize(20);                textView.setGravity(Gravity.CENTER);                textView.setBackgroundResource(colors[position]);                textView.setWidth(60);                textView.setHeight(60);                return textView;                             }                     };         gridview1.setAdapter(baseAdapter);              }  }

 3.测试

 当将界面布局文件中GridView的stretchMode设为none,点击按钮，输出的信息为columnWidth:160,widthSpace:16

当将界面布局文件中GridView的stretchMode设为spacingWidth,点击按钮，输出的信息为columnWidth:160,widthSpace:120

当将界面布局文件中GridView的stretchMode设为columnWidth,点击按钮，输出的信息为columnWidth:229,widthSpace:16

当将界面布局文件中GridView的stretchMode设为spacingWidthUniform,点击按钮，输出的信息为columnWidth:160,widthSpace:68
