BaseAdapter

BaseAdapter是为ListView、GridView适配数据的抽象类！

public class MainAdapter extends BaseAdapter{
     private LayoutInflater inflater;
     private Context        context;
     public MainAdapter(Context context){
            this.context=context;
            inflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }
    @返回记录的数量
    public int getCount() {
        // TODO Auto-generated method stub
        return num;
    }

    @获取点击的条目数据
    public Object getItem(int arg0) {
        // TODO Auto-generated method stub
        return arg0;
    }

    @获取点击条目的ID
    public long getItemId(int arg0) {
        // TODO Auto-generated method stub
        return arg0;
    }

    @适配数据
    public View getView(int arg0, View arg1, ViewGroup arg2) {
        // TODO Auto-generated method stub
        View view=inflater.inflate(R.layout.test, null);
        TextView tv_name=(TextView)view.findViewById(R.id.textView1);
        Button btn=(Button)view.findViewById(R.id.button1);
        tv_name.setText("标记");
        btn.setText("确认");
        return view;
    }

}

public class MainActivity extends Activity {
    GridView gridView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        GridView gridView = (GridView)findViewById(R.id.gridView1);
        gridView.setAdapter(new MainAdapter(this));

}
}

ProcessInfo info = (ProcessInfo) lv.getItemAtPosition(position);在为Item设置响应事件的时候，获取点击对象。
