Android基础之----GridView（网格视图）

                                                                                     GridView（网格视图）

先看效果：

实现：

package com.example.grideviewimpl;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import android.app.Activity;
import android.os.Bundle;
import android.widget.GridView;
import android.widget.SimpleAdapter;

public class MainActivity extends Activity {

    // V
    private GridView gridview;

    // M
    private String[] titles = { "1", "2", "3", "4", "5", "6" };

    private int[] images = { R.drawable.ic_launcher, R.drawable.ic_launcher,
            R.drawable.ic_launcher, R.drawable.ic_launcher,
            R.drawable.ic_launcher, R.drawable.ic_launcher };

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

    // C
    private SimpleAdapter SimpleAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 实例化V层
        gridview = (GridView) findViewById(R.id.gv);

        // 实例化适配器
        SimpleAdapter = new SimpleAdapter(MainActivity.this, getData(),
                R.layout.myitem, new String[]{"titles","images"}, new int[]{R.id.tv,R.id.iv});

        // 载入Gridview
        gridview.setAdapter(SimpleAdapter);

    }

    public List<Map<String, Object>> getData() {

        for (int i = 0; i < titles.length; i++) {
            HashMap<String, Object> map = new HashMap<String, Object>();
            map.put("images", images[i]);
            map.put("titles", titles[i]);
            this.list.add(map);
        }

        return list;
    }
}

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    tools:context="${relativePackage}.${activityClass}" >    <GridView        android:id="@+id/gv"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:gravity="center"        android:numColumns="3" >    </GridView></LinearLayout>

<?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" 
    android:gravity="center"
    >

    <ImageView
        android:id="@+id/iv"
        android:layout_width="50dp"
        android:layout_height="50dp" 
        android:gravity="center"
        />

    <TextView android:id="@+id/tv"
        android:layout_width="50dp"
        android:layout_height="30dp"
        android:gravity="center"         
        />

</LinearLayout>

先写代码吧，有时间再说详细点
