  };

 

          @Override

  protected void onCreate(Bundle savedInstanceState) {

  super.onCreate(savedInstanceState);

  setContentView(R.layout.activity_main);

  //1,找到控件

 

  gv = (GridView) findViewById(R.id.gv);

 

  //2,自定义适配器

  MyAdapter adapter=new MyAdapter();

  //3,加载

  gv.setAdapter(adapter);

 

  }

private class MyAdapter extends BaseAdapter{

 

          @Override

                    //1,找到布局

                     View view=View.inflate(getApplicationContext(), R.layout.gv_item, null);

                    //2,找到布局要操作的控件

                    ImageView iv= (ImageView) view.findViewById(R.id.iv_icon);

                    TextView tv=(TextView) view.findViewById(R.id.tv_desc);
