Question

how to convert value from getLongitude() and getLatitude() to format that can be accepted by the EditText?

it works if i put them into Toast like this

String message = "Current Location \nLongitude: "+location.getLongitude()+"\nLatitude: "+location.getLatitude();
Toast.makeText(getApplicationContext(), message, Toast.LENGTH_LONG).show();

but if i put them into EditText like this, the application will stopped and error

tv_obj_long.setText(location.getLongitude());
tv_obj_lat.setText(location.getLatitude());

i think the format is wrong, i’m trying with Double.toString() but it still error

how to fix this?

thanks

this is my code on the button

btn_obj_useKor.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View arg0) {
      showCurrentLocation();
   }
});

this is the function called by the button

public void showCurrentLocation() {
        Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
        if (location != null) {
                showToastStatus(location);
                tv_obj_long.setText(String.valueOf(location.getLongitude()));
                tv_obj_lat.setText(String.valueOf(location.getLatitude()));
            }else{
                Toast.makeText(getApplicationContext(), "Terjadi Kesalahan dalam pengambilan koordinat", Toast.LENGTH_LONG).show();
        }
    };

this is the toast that works

public void showToastStatus(Location location){
        String message = "Current Location \nLongitude: "+location.getLongitude()+"\nLatitude: "+location.getLatitude();
        Toast.makeText(getApplicationContext(), message, Toast.LENGTH_LONG).show();
    }

and this is my xml

<TextView
        android:text="Longitude"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"/>
      <EditText
        android:id="@+id/tv_obj_long"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"/>
      <TextView
        android:text="Latitude"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"/>
      <EditText
        android:id="@+id/tv_obj_lat"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"/>

I know the problem now,

I placed the declaration in wrong place

Look at this

public void showCurrentLocation() {
        Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
        if (location != null) {
                showToastStatus(location);
                tv_obj_long.setText(String.valueOf(location.getLongitude()));
                tv_obj_lat.setText(String.valueOf(location.getLatitude()));
            }else{
                Toast.makeText(getApplicationContext(), "Terjadi Kesalahan dalam pengambilan koordinat", Toast.LENGTH_LONG).show();
        }
    };

i added this code on second line

final TextView error_text = (TextView) findViewById(R.id.error_text);

and it works!!

i placed that code in onCreate before
T___T
