我想使用我的地方选择器将标记详细信息保存到android中的SQLite数据库。但是当我运行应用程序时，它会崩溃。有人可以告诉我哪里出错了。
我的数据库处理程序
public class HistoryDBHandler extends SQLiteOpenHelper {
private static final int DATABASE_VERSION = 1; // version
private static final String DATABASE_NAME = "searches.db"; // file saving on device
public static final String TABLE_HISTORY = "History"; // table name
public static final String COLUMN_ID = "PLACE ID";
public static final String COLUMN_NAME = "NAME";
public static final String COLUMN_ADDRESS = "ADDRESS";
public HistoryDBHandler(Context context, String name, SQLiteDatabase.CursorFactory factory, int version) {
super(context, DATABASE_NAME, factory, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
String query = "CREATE TABLE" + TABLE_HISTORY + "(" +
COLUMN_ID + " INT PRIMARY KEY AUTO INCREMENT " +
COLUMN_NAME + " TEXT " +
COLUMN_ADDRESS + " TEXT " + ")";
db.execSQL(query);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
}
public void addHistory(HistorySQLite history){
ContentValues values = new ContentValues();
values.put(COLUMN_NAME, history.get_name());
SQLiteDatabase db = getWritableDatabase();
db.insert(TABLE_HISTORY, null, values);
db.close();
}
// print out database as string
public String printHistory(){
String dbString ="";
SQLiteDatabase db = getWritableDatabase();
String query = "SELECT * FROM " + TABLE_HISTORY + "WHERE 1";
db.close();
return dbString;
}
}
构造
public class HistorySQLite {
private int _id;
private String _address;
private String _name;
public HistorySQLite(String _address, String _name, int _id){
this._address = _address;
this._name = _name;
}
public HistorySQLite(){
}
public void set_id(int _id) {
this._id = _id;
}
public void set_address(String _address) {
this._address = _address;
}
public void set_name(String _name) {
this._name = _name;
}
public int get_id() {
return _id;
}
public String get_address() {
return _address;
}
public String get_name() {
return _name;
}
}
这是我要求执行意图并添加到数据库
的地方选择器 Place place = PlacePicker.getPlace(data, this);
LatLng placeLatLng = place.getLatLng(); // gett lat lng from place
double placeLat = placeLatLng.latitude;
double placeLong = placeLatLng.longitude;
final CharSequence name = place.getName();
final CharSequence address = place.getAddress();
final LatLng location = place.getLatLng();
Marker destination = mMap.addMarker(new MarkerOptions().position(new LatLng(placeLat, placeLong)).title("This is your destination"));
LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
//Current Location
Criteria criteria = new Criteria();
String provider = locationManager.getBestProvider(criteria, true);
Location myLocation = locationManager.getLastKnownLocation(provider);
//Current Location LatLong
final double currentLat = myLocation.getLatitude();
final double currentLng = myLocation.getLongitude();
HistorySQLite history = new HistorySQLite(name.toString(),address.toString(), 1);
//Directions From Current Location To Destination
final Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://maps.google.com/maps?" + "saddr=" + currentLat + "," + currentLng + "&daddr=" + placeLat + "," + placeLong));
intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");
startActivity(intent);
historyDBHandler.addHistory(history);
}
在
中调用数据库historyDBHandler = new HistoryDBHandler(this, null, null , 1); // allows the handler to control the content
// printDatabase();
}
public void printDatabase(){
String dbString = historyDBHandler.printHistory();
textView2.setText(dbString);
}
logcat的

你有＆＃34;创建表＆＃34;语法错误在dbHandler中的onCreate方法中。 试试这个：
public void onCreate(SQLiteDatabase db) {
String query = "CREATE TABLE " + TABLE_HISTORY + "(" +
COLUMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
COLUMN_NAME + " TEXT, " +
COLUMN_ADDRESS + " TEXT " + ");";
db.execSQL(query);
}

创建表语法错误： 更改代码：
String query = "CREATE TABLE" + TABLE_HISTORY + "(" +
COLUMN_ID + " INT PRIMARY KEY AUTO INCREMENT " +
COLUMN_NAME + " TEXT " +
COLUMN_ADDRESS + " TEXT " + ")";
db.execSQL(query);
}
To
String query = "CREATE TABLE" + TABLE_HISTORY + "(" +
+ COLUMN_ID + " INTEGER PRIMARY KEY AUTO INCREMENT ,"
+ COLUMN_NAME + " TEXT,"
+ COLUMN_ADDRESS + " TEXT" + ")";
db.execSQL(query);
}
