GridView视图

本文实现如下效果

Test_Grid.java

public class Test_Grid extends Activity {
    private GridView gridview;
    private int[] ids={R.drawable.s1,R.drawable.s2,R.drawable.s3,R.drawable.s4,R.drawable.s5};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.grid);
        gridview =(GridView)findViewById(R.id.girdview);
        //设置一行显示几个
        gridview.setNumColumns();
        gridview.setAdapter(new MyGirdAdapter());
        gridview.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                Toast.makeText(Test_Grid.this, ""+position, ).show();

            }
        });
    }

    private class MyGirdAdapter extends BaseAdapter
    {

        @Override
        public int getCount() {
            // TODO Auto-generated method stub
            return ids.length;
        }

        @Override
        public Object getItem(int position) {
            // TODO Auto-generated method stub
            return ids[position];
        }

        @Override
        public long getItemId(int position) {
            // TODO Auto-generated method stub
            return position;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            ImageView image;
            if(convertView==null)
            {
                image=new ImageView(Test_Grid.this);
                image.setLayoutParams(new GridView.LayoutParams(,));
                image.setScaleType(ImageView.ScaleType.CENTER_CROP);
                image.setPadding(, , , );
            }
            else
                image=(ImageView)convertView;

            image.setImageResource(ids[position]);
            return image;
        }

    }

}
