Android中GridView来显示图片

pu
blic class MainActivity extends Activity {

	private GridView gridView;

	private int res[] = new int[] {R.drawable.an01,
			R.drawable.an02, R.drawable.an03, R.drawable.an01, R.drawable.an02,
			R.drawable.an03,R.drawable.an01,

			R.drawable.an03,R.drawable.an01,
			R.drawable.an02, R.drawable.an03, R.drawable.an01, R.drawable.an02,
			R.drawable.an03 };

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		gridView = (GridView) findViewById(R.id.gridView1);
		
		
		 List<Map<String, Object>> data = new ArrayList<Map<String,Object>>();
		 
		 for(int i=0;i<res.length;i++){
		 Map<String,Object> map = new HashMap<String, Object>();
		    map.put("imageView",res[i]);
		    
		    data.add(map);
		 }
				 
		SimpleAdapter 易做图Adapter = new SimpleAdapter(this, data,R.layout.activity_cell , new String[]{"imageView"}, new int[]{R.id.imageView1});
		
		gridView.setAdapter(易做图Adapter);
		
		
		
		//思考题 在Gridview中 SimpleAdpater  图片添加事件
		
		gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

			@Override
			public void onItemClick(AdapterView<?> parent, View view,
					int position, long id) {
				//可以显示图片大图
				Toast.makeText(getApplicationContext(), "xxxx"+res[position], Toast.LENGTH_LONG).show();
				
			}
		});
		
		
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
