android 实时添加图片和文字到listview，如何实现？

Answer 1

在activity里面调用addOne就可以了。
图片和文字的显示需要自己写layiout文件R.layout.music_playlist_item

public class MusicPlayListAdapter extends BaseAdapter {

List<? extends PlayListInfo> data;

public MusicPlayListAdapter(List<? extends PlayListInfo> data) {
this.data = data;
}

public void addOne(PlayListInfo music) {
data.add(music);
notifyDataSetChanged();
}

@Override
public int getCount() {
return data.size();
}

@Override
public Object getItem(int position) {
return data.get(position);
}

@Override
public long getItemId(int position) {
return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = LayoutInflater.from(context).inflate(
R.layout.music_playlist_item, null);
}

PlayListInfo music = data.get(position);
........

return convertView;
}

}

Answer 2

写一个自定义的adapter，一个单项的layout
