在我的应用中,我传递给适配器(扩展了ArrayAdapter&gt;)这样的列表:List<Map<String, String>>
。此列表中的单个记录如下所示:{received=true, text=Some sort of text}
这是我的getView方法:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
Map<String, String> singleRecord = new HashMap<String, String>();
singleRecord = records.get(position);
View rowView = convertView;
if (rowView == null) {
LayoutInflater layoutInflater = context.getLayoutInflater();
rowView = layoutInflater.inflate(record_layout, null);
}
//To test get method I do:
String to_put = singleRecord.get(KEY_TEXT);
Log.e("Adapter", to_put);
////
TextView singleText = (TextView) rowView.findViewById(R.id.singleID);
singleText.setText(singleRecord.get(KEY_TEXT));
//viewHolder.singleText.setText(tekst);
return super.getView(position, convertView, parent);
}
正如你所看到的,我希望我的TextView能够使用key来设置我的地图所包含的文本:&#34; KEY_TEXT&#34 ;;为了测试get方法是否正常工作我把它放在Log中它看起来是正确的,但是当我将textview的文本设置为我放入LogCat(来自地图的文本)的相同文本时,我没有得到密钥的值:&#34; KEY_TEXT&#34;,我得到的内容如下:{received=true, text=Some sort of text}
所以它只是一个转换为String的记录。有人知道为什么会这样吗?
答案 0 :(得分:0)
请使用以下代码:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
Map<String, String> singleRecord = new HashMap<String, String>();
View vi = convertView;
singleRecord = records.get(position);
vi = mLayoutInflater.inflate(R.layout.record_layout, null);
TextView tv1 = (TextView) vi
.findViewById(R.id.singleID);
tv1.setText(singleRecord.get(KEY_TEXT));
return vi;
}
