GridView 简单使用

GridView  最 简单使用示例。

布局：

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:orientation="vertical"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:background="@drawable/bg"

    android:gravity="center_horizontal"

    >

    

    <include layout="@layout/top_bar" />

<View   

    android:layout_width="fill_parent"

    android:layout_height="1dip"

    android:background="#FF789977"

    />

     

    <EditText  android:id="@+id/search"

      android:layout_width="fill_parent"

     android:layout_height="wrap_content"

     android:hint="输入查询"

      

     android:drawableRight="@drawable/ic_btn_search"

     />

 

   <GridView   android:id="@+id/gr"

     android:layout_width="wrap_content"

     android:layout_height="wrap_content"

     android:horizontalSpacing="8dip"

     android:verticalSpacing="10dip"

     android:numColumns="3"

     android:gravity = "center"

     android:stretchMode="columnWidth"

     android:layout_marginLeft="3dip"

      android:layout_marginRight="3dip"

     

     />

    

</LinearLayout>

R.cell.xml:

<?xml version="1.0" encoding="utf-8"?>

 <RelativeLayout    xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="wrap_content"

    >

 <ImageView    

    android:id="@+id/image"

    android:layout_width="wrap_content"

    android:layout_height="90dip"

    />

    

 <TextView android:layout_width="wrap_content"

  android:layout_below="@id/image" android:layout_height="wrap_content"

  android:text="TextView01" android:layout_centerHorizontal="true"

  android:textColor="#FF45b576"

  android:id="@+id/itemText">

</TextView>

</RelativeLayout>

代码：

public class mActivity extends Activity {

    

  

    

    private  List<Map<String,Object> > items;

 

 

    private int imgIds[] = new int[]{R.drawable.ktv,R.drawable.ktv1,R.drawable.ktv2,

                                    R.drawable.ktv3,R.drawable.ktv4,R.drawable.ktv5,

                                    R.drawable.ktv8,R.drawable.ktv7,R.drawable.ktv6,};

     

    private String ktvnames[] ={"音乐房子","浪漫","匣子Kbox",

                            "心动KTV","糖果","快乐歌声",

                            "榕树歌城","好乐迪","欢乐迪"};

    

    

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        this.requestWindowFeature(Window.FEATURE_NO_TITLE);

        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,

                WindowManager.LayoutParams.FLAG_FULLSCREEN);

        setContentView(R.layout.main5);

  

        

        items = new ArrayList<Map<String,Object>>();

        for ( int i =0; i<imgIds.length; i++){

            

            Map<String,Object> item = new HashMap<String,Object>();

            item.put("img", imgIds[i]);

            item.put("ktvname", ktvnames[i]);

            items.add(item);

            

        }

        

        

        SimpleAdapter  adapter = new SimpleAdapter(this, items, R.layout.cell,

                new String[]{"img","ktvname"}, new int[]{R.id.image,R.id.itemText}){

            

        };

        

        

        GridView  gd = (GridView)findViewById(R.id.gr);

        gd.setAdapter(adapter);

        

        //滚动滑轮 选择

        gd.setOnItemSelectedListener(new OnItemSelectedListener(){

            @Override

            public void onItemSelected(AdapterView<?> arg0, View arg1,

                    int pos, long arg3) {

                

                Toast.makeText(mActivity.this, "选中了"+ ktvnames[pos] +"KTV", Toast.LENGTH_SHORT).show();

                

            }

            @Override

            public void onNothingSelected(AdapterView<?> arg0) {

                

                

            }});

       

 }
