Android原生Gps取得位置決め
11788 ワード
去年は会社がこれを使っていたので、忘れてしまいましたが、今年はまたこの機能を整理してみましょう.
いつものように、コピーが使えます!!!各クラスをコピーすればいい!!!
まず、ツールクラスです.
GPS測位、最初のクラス
GPS管理者クラス
GPS測位情報
GPS測位イベント
使用方法、クリックイベントで呼び出す:
MyListenをカスタマイズし、Activityまたは別の場所で1つカスタマイズすればいいです.
Handlerで詳細情報を取得し、ActivityでHandler全体を表示します.
アドレス位置決めを取得すると微小なばらつきがあり,原生位置決めに起因する.

}使用方法、クリックイベントで呼び出す:
TextView textView = (TextView) findViewById(R.id.getLaocation);
textView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
GPSLocationManager gpsManager = GPSLocationManager.getInstances(MainActivity.this);
gpsManager.setHandler(handler);
//
GPS_FIRST_FIX = true;
gpsManager.start(new MyListener(), true);
}
});
MyListenをカスタマイズし、Activityまたは別の場所で1つカスタマイズすればいいです.
class MyListener implements GPSLocationListener {
@Override
public void UpdateLocation(Location location) {
if (location != null) {
log = location.getLongitude();
lat = location.getLatitude();
if (GPS_FIRST_FIX = true) {
gpsManager.start_TimerTask();
GPS_FIRST_FIX = false;
}
Log.e("gps==", " ：" + location.getLongitude() + "
：" + location.getLatitude());
}
}
@Override
public void UpdateStatus(String provider, int status, Bundle extras) {
if ("gps" == provider) {
Log.e("UpdateStatus--gps", " ：" + provider);
}
}
@Override
public void UpdateGPSProviderStatus(int gpsStatus) {
switch (gpsStatus) {
case GPSProviderStatus.GPS_ENABLED:
// Toast.makeText(MainActivity.this, "GPS ", Toast.LENGTH_SHORT).show();
break;
case GPSProviderStatus.GPS_DISABLED:
// Toast.makeText(MainActivity.this, "GPS ", Toast.LENGTH_SHORT).show();
break;
case GPSProviderStatus.GPS_OUT_OF_SERVICE:
// Toast.makeText(MainActivity.this, "GPS ", Toast.LENGTH_SHORT).show();
break;
case GPSProviderStatus.GPS_TEMPORARILY_UNAVAILABLE:
// Toast.makeText(MainActivity.this, " GPS ", Toast.LENGTH_SHORT).show();
break;
case GPSProviderStatus.GPS_AVAILABLE:
// Toast.makeText(MainActivity.this, "GPS ", Toast.LENGTH_SHORT).show();
break;
}
}
}
Handlerで詳細情報を取得し、ActivityでHandler全体を表示します.
Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
// TODO Auto-generated method stub
//
super.handleMessage(msg);
Geocoder gc = new Geocoder(MainActivity.this, Locale.getDefault());
List locationList = null;
try {
locationList = gc.getFromLocation(lat, log, 1);
} catch (IOException e) {
e.printStackTrace();
}
if (locationList.size() > 0) {
Address address = locationList.get(0);// Address
String locality = address.getLocality();// ， ：
String addressLine = address.getAddressLine(0);// ， ，i=0，
Log.e("motejia", "handleMessage: =============="+locality+"========="+addressLine);
}
// Handler
}
};アドレス位置決めを取得すると微小なばらつきがあり,原生位置決めに起因する.
