继承baseadapter怎么实现

Posted 2023-03-14

参考技术A 1)mListView = (ListView) findViewById(R.id.listView);
mListView.setAdapter(new mListAdapter(this, getdata2()));
//设置Adapter的时候，用this传Context，不要用getApplicationContext()

2)public mListAdapter(Context context, List<HashMap<String, Object>> list)
this.mContext = context;
this.mHashMaps = list;
//将Context传入自定义Adapter中

3)private void ShowInfo()
new AlertDialog.Builder(mContext).setTitle("my listview").setMessage("introduce....").
setPositiveButton("OK", new DialogInterface.OnClickListener()

@Override
public void onClick(DialogInterface dialog, int which)
// TODO Auto-generated method stub


).show();
//这样Builder(mContext)就OK了本回答被提问者采纳
