GridView android学习

  @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        GridView gridview = (GridView)findViewById(R.id.gridview_red);
        BaseAdapter adapters = new GridAdaper((LayoutInflater) this.getSystemService(GridViewActivity.this.LAYOUT_INFLATER_SERVICE));
        gridview.setAdapter(adapters);
    }

    class GridAdaper extends BaseAdapter{
    	private LayoutInflater mInflater;
    	
    	private List<Integer> list = new ArrayList<Integer>();
    	
    	public GridAdaper(LayoutInflater  flater){
    		super();
    		this.mInflater = flater;
    		for(int i = 0; i< 50; i++)
    		list.add(i);
    	}
    	
    	
		@Override
		public View getView(int position, View convertView, ViewGroup parent) {
			if(convertView == null){
				convertView = mInflater.inflate(R.layout.grid_item, null);

			RelativeLayout layOut = (RelativeLayout) convertView;
			ImageView imageView = (ImageView) layOut.findViewById(R.id.itemImage);
			imageView.setImageResource(R.drawable.grid_ball);
			TextView textView = (TextView) layOut.findViewById(R.id.itemText);
			if(list != null && list.size() > 0){
				textView.setText(""+list.get(position));
			}else{
				textView.setText("null");
			}
			
			layOut.setOnTouchListener(new OnTouchListener() {
				
				@Override

					return false;

			return convertView;
		}
		
		@Override
		public long getItemId(int position) {
			return position;
		}
		
		@Override

    }

 

关键的配置文件：
