我试图更新控制通过sendListCountWithContent()方法2 ListView项内容（有一个的TextView）上的SmartWatch：的SmartWatch 2的sendListCountWithContent（）抛出ClassCastException异常
public class SmartWatch2Control extends ControlExtension {
private List<String> accs;
@Override
public void onResume() {
accs = Utils.getAllAccounts();
showLayout(R.layout.smartwatch2, null);
sendListCountWithContent(R.id.smartwatch2_list, accs.size(),
bundlesForList(accs));
sendListPosition(R.id.smartwatch2_list, 0);
}
private Bundle[] bundlesForList(List<String> list) {
Bundle[] result = new Bundle[list.size()];
for (int i = 0; i < list.size(); i++) {
Bundle nameBundle = new Bundle();
nameBundle.putInt(Control.Intents.EXTRA_LAYOUT_REFERENCE,
R.id.acc_name);
nameBundle.putString(Control.Intents.EXTRA_TEXT, list.get(i));
Bundle[] views = new Bundle[] { nameBundle };
Bundle b = new Bundle();
b.putInt(Control.Intents.EXTRA_DATA_XML_LAYOUT,
R.layout.smartwatch2_item);
b.putInt(Control.Intents.EXTRA_LIST_ITEM_ID, i);
b.putInt(Control.Intents.EXTRA_LIST_ITEM_POSITION, i);
b.putParcelableArray(Control.Intents.EXTRA_LAYOUT_DATA, views);
result[i] = b;
}
return result;
}
}
当我尝试启动上的SmartWatch 2模拟器我的应用得到异常：

索尼并没有提供API方法网页的javadoc（仅在帐篷），所以我在这里的摘录：
package com.sonyericsson.extras.liveware.extension.util.control;
public abstract class ControlExtension {
<..>
protected void sendListCountWithContent(int layoutReference, int listCount, Bundle[] bundles) {
Intent intent = new Intent(Control.Intents.CONTROL_LIST_COUNT_INTENT);
intent.putExtra(Control.Intents.EXTRA_LAYOUT_REFERENCE, layoutReference);
intent.putExtra(Control.Intents.EXTRA_LIST_COUNT, listCount);
intent.putExtra(Control.Intents.EXTRA_LIST_CONTENT, bundles);
sendToHostApp(intent);
}
<..>
}
当我调用sendListCountWithContent方法应用发送CONTROL_LIST_COUNT_INTENT意图到主机应用程序（的SmartConnect），则主机应用程序重新发送意图仿真器（或连接SmartWatch2），其它建立一个基于布局对意向演员。这里抛出一个ClassCastException。
我不确定，但它看起来像模拟器中的错误。
