我有一个ListView,我绑定到适配器。适配器是我的主类的受保护成员。我有一个侦听器线程,它接收数据并更新我的适配器的源列表。当我调用适配器的notifyDataSetChanged()方法时,抛出异常:
运行时异常:PhoneLayoutInflater(LayoutInflater).inflate(int, ViewGroup,boolean)line:322
我已经读过必须在UI线程上调用notifyDataSetChanged()方法,而我正在这样做。实际上,为了确保,我甚至在UI线程上更新了ListView的数据源。我在侦听器线程中所做的就是更新一个包含数据的受保护成员。这是我正在做的一个例子(请注意,我没有调用AsyncTask的代码部分,但它是从侦听器触发的):
public class main extends Activity() {
protected LinkedList<HashMap<String, String>> adapterDataList = new LinkedList<HashMap<String, String>>();
protected MyDataObject dataObject;
protected SimpleAdapter dataAdapter;
@Override
public void onCreate(Bundle savedInstanceState) {
//call parent oncreate
super.onCreate(savedInstanceState);
//display the main form
setContentView(R.layout.main);
//get a handle on the score list view elements
ListView dataList = (ListView)(findViewById(R.id.datalist));
//link the adapter and the data source
dataAdapter = new SimpleAdapter(this, adapterDataList, R.layout.row, new String[]{"name","address"}, new int[]{R.id.username,R.id.address});
dataList.setAdapter(dataAdapter);
}
protected void refreshData() {
adapterDataList.clear();
Iterator<MyData> iter = MyDataObject.iterator();
while(iter.hasNext()) {
HashMap<String, String> item = new HashMap<String, String>()
item.put("name", iter.name);
item.put("address", iter.address);
adapterDataList.add(item);
}
dataAdapter.notifyDataSetChanged();
}
private class DataTask extends AsyncTask<Data, Void, Data> {
protected void onPostExecute(Data data) {
dataObject = data;
runOnUiThread (new Runnable() { public void run() {
refreshScores();
}});
}
}
...
}
有没有人对我为什么会遇到此异常有任何指示或想法?非常感谢任何帮助。
修改 以下是布局文件,如下所示: main.xml中:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ptl="http://schemas.android.com/apk/res/com.mod0.pubtrivialive"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/datalistcontainer">
<ListView android:id="@+id/datalist"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
row.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:paddingBottom="6dip"
android:paddingTop="4dip">
<TextView android:id="@+id/name"
android:layout_width="80dip"
android:layout_height="wrap_content" />
<TextView android:id="@+id/address"
android:layout_height="wrap_content"
android:layout_weight="1" />
</LinearLayout>
答案 0 :(得分:0)
这看起来不正确dataList.clear();
。您确定要在dataList
而不是adapterDataList
上打电话给您明确的意思吗?
