此项目需要两个类。
BroadcastReceiver
(上课) - 接收短信; ListActivity
(课程) - 显示短信; 由于setListAdapter()
方法需要定义ListActivity
(类),我的问题是如何在以下代码中定义这两个类?
import ....
public class SmsReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent)
{
//---get the SMS message passed in---
Bundle bundle = intent.getExtras();
SmsMessage[] msgs = null;
String str = "";
if (bundle != null)
{
//---retrieve the SMS message received---
Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
for (int i=0; i<msgs.length; i++){
msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
str += "SMS from " + msgs[i].getOriginatingAddress();
}
//----REQUIRE ListActivity(class) to define----//
// how should i define the class here???
//---display in list---
setListAdapter(new ArrayAdapter<String>(this, R.layout.main,str));
ListView listView = getListView();
listView.setTextFilterEnabled(true);
//---method is call when listitem is clicked---
listView.setOnItemClickListener(new OnItemClickListener() {
//described method
});
}
}

根据我的最简单的解决方案是:
1将所有项目存储在扩展BroadcastReceiver
2将带有Intent
的列表传递给扩展ListActivity
的

Kin,您还可以在不扩展列表视图的活动中设置列表视图。请参阅此example。
