如何将数据从主活动传递到android中的数据库

Question

MainActivity

@Override
public void onLocationChanged(Location location) {
    Log.d(TAG, "Firing onLocationChanged..............................................");
    mCurrentLocation = location;
    mLastUpdateTime = DateFormat.getTimeInstance().format(new Date());
    String lat = String.valueOf(mCurrentLocation.getLatitude());
    String lng = String.valueOf(mCurrentLocation.getLongitude());

}

Database.java

public void insertSettings(String lattitude, String longitude)
{
    SQLiteDatabase db = getReadableDatabase();
    ContentValues values = new ContentValues();
    values.put(LATTITUDE, lattitude);
    values.put(LONGITUDE, longitude);
    db.insertOrThrow(LOCATE_TABLE, null, values); 
}

我需要将字符串lat和字符串lng传递给数据库...我是新的......所以请原谅我的错误并请求帮助。
