Я пытаюсь соединить мою базу данных в два Editview и одно Textview. edit-views хранят, но проблема с сохранением текстовых представлений, я хотел бы сохранить значения Geo points (Lat & Lang) в виде TextView в моей базе данных. Вот мой код
public class Mydatabase4meActivity extends Activity {
/** Called when the activity is first created. */
ArrayList<String> al=new ArrayList<String>();
EditText username_edt,pass_edt;
Bitmap b;
Button login_but;
MyDatabase mdb;
ImageView iv;
SQLiteDatabase sqlite;
TextView tv;
Cursor c;
LocationManager mlocManager;
LocationListener mlocListener;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
username_edt=(EditText)findViewById(R.id.editText1);
pass_edt=(EditText)findViewById(R.id.editText2);
login_but=(Button)findViewById(R.id.button1);
tv=(TextView)findViewById(R.id.textView1);
// text view
mlocManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
mlocListener = new MyLocationListener();
for (String provider: mlocManager.getAllProviders()) {
System.out.println(provider);
Location loc = mlocManager.getLastKnownLocation(provider);
if (loc != null) {
Double latitude = loc.getLatitude();
Double longitude = loc.getLongitude();
String Text = "Current location for provider "+ provider + ":" + "Lat=" + latitude.toString() + " Long=" + longitude.toString();
//tv.getTag(Text);
tv.setText(Text);
//Toast.makeText( getApplicationContext(), Text, Toast.LENGTH_SHORT).show();
}
}
mlocManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 0, 0, mlocListener);
}
public class MyLocationListener implements LocationListener
{
public void onLocationChanged(Location loc) {
// TODO Auto-generated method stub
loc.getLatitude();
loc.getLongitude();
String Text = "My current location is: "+ "Latitud =" + loc.getLatitude() +
"Longitud = " + loc.getLongitude();
//tv.setText(Text);
tv.setText(Text = "My current location is: "+ "Latitud =" + loc.getLatitude() +
"Longitud = " + loc.getLongitude());
//Toast.makeText( getApplicationContext(),Text,Toast.LENGTH_SHORT).show();
}
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
tv.getText();
Toast.makeText( getApplicationContext(),"Gps Disabled",Toast.LENGTH_SHORT ).show();
}
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
tv.getText();
Toast.makeText( getApplicationContext(),"Gps Enabled", Toast.LENGTH_SHORT).show();
}
public void onStatusChanged(String provider, int status,
Bundle extras) {
// TODO Auto-generated method stub
}
}
@Override
protected void onDestroy() {
super.onDestroy();
if (mlocManager != null) {
mlocManager.removeUpdates(mlocListener);
mlocManager = null;
}
// login button
login_but.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mdb=new MyDatabase(getApplicationContext(), "abcdef", null, 1);
sqlite=mdb.getWritableDatabase();
ContentValues cv=new ContentValues();
cv.put("Employeename", username_edt.getText().toString());
cv.put("password", pass_edt.getText().toString());
cv.put("coordinates", tv.getText().toString());
sqlite.insert("employee", null, cv);
String col[]={"Employeename","password","coordinates"};
c=sqlite.query("employee",col, null, null, null, null, null);
if(c!=null){
c.moveToFirst();
do{
int i=c.getInt(c.getColumnIndex("Employeename"));
al.add(""+i);
String str=c.getString(c.getColumnIndex("coordinates"));
al.add(str);
String str1=c.getString(c.getColumnIndex("password"));
al.add(str1);
}while(c.moveToNext());
}
mdb.close();
sqlite.close();
}
});
Toast.makeText(getApplicationContext(), "data is inserted", Toast.LENGTH_SHORT).show();
}
}
вот это класс myDatabase
public class MyDatabase extends SQLiteOpenHelper{
public MyDatabase(Context context, String name, CursorFactory factory,
int version) {
super(context, name, factory, version);
// TODO Auto-generated constructor stub
}
@Override
public void onCreate(SQLiteDatabase db) {
// TODO Auto-generated method stub
db.execSQL("create table employee(Employeename varchar2(10),password integer(10),coordinates varchar2(7,2));");
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
// TODO Auto-generated method stub
}
}
