Android学习笔记 - 网格视图(GridView)

1. 利用网格视图(GridView)物件来呈现项目列表

2. MainActivity.java

package org.me.android_gridview;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.GridView;
import android.widget.Toast;

public class MainActivity extends Activity {
    private GridView gridView;
    
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.main);
        gridView = (GridView) findViewById(R.id.gridView);
        final String[] list = new String[]{"王建民","郭泓志","倪福德","胡金龙"};
        //设定列表内容
        ArrayAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1,list);
        //设定列数
        gridView.setNumColumns(2);
        gridView.setAdapter(adapter);
        //项目被点选时，回应的动作
        gridView.setOnItemClickListener(new GridView.OnItemClickListener(){
           @Override
           public void onItemClick(AdapterView adapterView,View view,int position,long id) {
               Toast.makeText(MainActivity.this, "您选择的是"+list[position], Toast.LENGTH_SHORT).show();
           }
        });
    }
}
