我想创建一个简单的加载器对话框，直到它连接到卫星。 我该如何管理？在调用此方法之前，如何检查它是否先连接到卫星？ 谢谢你的回答！
答案 0 :(得分：2)
您需要为此实施GpsStatus.Listener。
例如，
public class MyActivity extends Activity implements GpsStatus.Listener
{
...
...
...
// add listener into locationManager
locationManager.addGpsStatusListener(this);
@Override
public void onGpsStatusChanged(int)
{
switch (event)
{
case GpsStatus.GPS_EVENT_SATELLITE_STATUS:
break;
case GpsStatus.GPS_EVENT_FIRST_FIX: // this means you found GPS Co-ordinates
break;
case GpsStatus.GPS_EVENT_STARTED:
break;
case GpsStatus.GPS_EVENT_STOPPED:
break;
}
}
}

您可以弹出对话框，请求位置更新，然后在实际获得位置更新时关闭对话框。
答案 2 :(得分：0)
让您Activity实施GpsStatus.Listener
然后使用：
public void onChanged(int event) {
switch (event) {
case GpsStatus.GPS_EVENT_SATELLITE_STATUS:
break;
case GpsStatus.GPS_EVENT_FIRST_FIX:
break;
case GpsStatus.GPS_EVENT_STARTED:
break;
case GpsStatus.GPS_EVENT_STOPPED:
break;
}
}
GpsStatus.GPS_EVENT_FIRST_FIX是GPS系统自启动以来收到首次修复时发送的事件。
