Question

继承baseadapter怎么实现

Answer 1

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
