Android應用中使用GridView實現數據網格顯示

Android應用中使用GridView實現數據網格顯示

UsingGridView.java源碼：

package com.sinaapp.ssun.girdview; import java.util.*; import android.app.Activity; import android.os.Bundle; 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; public class UsingGridViewActivity extends Activity { private GridView gridView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); gridView = (GridView) this.findViewById(R.id.gridView); show(); } private void show() { List<HashMap<String, Object>> data = new ArrayList<HashMap<String, Object>>(); for(int i=0; i<12; i++){ HashMap<String, Object> hm = new HashMap<String, Object>(); hm.put("image", R.drawable.ic_launcher); hm.put("name", "NO." + i); data.add(hm); } SimpleAdapter adapter = new SimpleAdapter(this, data, R.layout.item, new String[]{"image","name"},new int[]{R.id.imageView,R.id.textView}); gridView.setAdapter(adapter); gridView.setOnItemClickListener(new OnItemClickListener(){ @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { HashMap<String, Object> hm = (HashMap<String, Object>)parent.getItemAtPosition(position); Toast.makeText(UsingGridViewActivity.this, hm.get("name").toString(), Toast.LENGTH_LONG).show(); }}); } }

main.xml文件：

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <GridView android:id="@+id/gridView" android:layout_width="wrap_content" android:layout_height="match_parent" android:numColumns="3" > </GridView> </LinearLayout>

item.xml文件：

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <ImageView android:id="@+id/imageView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/ic_launcher" android:layout_gravity="center_horizontal"/> <TextView android:id="@+id/textView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal"/> </LinearLayout>
