GridView就是先将控件横向显示，然后纵向显示
效果如上所示
先看一下GridView的布局文件
<?xml version="1.0" encoding="utf-8"?> <GridView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/brainheroall" android:background="#FFeff1ef" android:layout_width="fill_parent" android:layout_height="wrap_content" android:numColumns="auto_fit" android:verticalSpacing="10dp" android:horizontalSpacing="10dp" android:columnWidth="90dp" android:stretchMode="columnWidth" android:gravity="center" />
这是如何显示GridView，下面的xml文件是GridView里面如何显示
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="wrap_content" android:paddingBottom="4dip" android:layout_width="fill_parent"> <ImageView android:layout_height="wrap_content" android:id="@+id/ItemImage" android:layout_width="wrap_content" android:layout_centerHorizontal="true"> </ImageView> <TextView android:layout_width="wrap_content" android:layout_below="@+id/ItemImage" android:layout_height="wrap_content" android:text="" android:textColor="#FF000000" android:layout_centerHorizontal="true" android:id="@+id/ItemText"> </TextView> </RelativeLayout>
下面是Java代码如何使用GridView
package view;import java.util.ArrayList;import java.util.HashMap;import model.HeroSimpleInfo;import service.ObtainInfo;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.KeyEvent;import android.view.View;import android.widget.AdapterView;import android.widget.AdapterView.OnItemClickListener;import android.widget.GridView;import android.widget.SimpleAdapter;import android.widget.Toast;import com.zhychneg.dota.R;public class BrainHeroActivity extends Activity implements OnItemClickListener{ GridView gv=null; long exitTime=0; HeroSimpleInfo []heros=null; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.brainheroall); gv=(GridView) findViewById(R.id.brainheroall); ArrayList<HashMap<String,Object>> al=new ArrayList<HashMap<String,Object>>(); heros=ObtainInfo.getBrainHeroSimpleInfo(); for(int i=0;i<heros.length;i++) { HashMap<String, Object> map = new HashMap<String, Object>(); map.put("icon", heros[i].getRes());//添加图像资源的ID map.put("name", heros[i].getName());//按序号做ItemText al.add(map); } SimpleAdapter sa=new SimpleAdapter(this,al,R.layout.gridview_layout,new String[]{"icon","name"},new int[]{R.id.ItemImage,R.id.ItemText}); gv.setAdapter(sa); gv.setOnItemClickListener(this); } public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Intent intent =new Intent(this,AboutHeroActivty.class); intent.putExtra("HERO", heros[position]); this.startActivity(intent); } }
