448 PointsI keep getting error messages and I am following along
This is my main activity code
package com.teamrandom.stormy;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import java.io.IOException;
import okhttp3.Call;
import okhttp3.Callback;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;
public class MainActivity extends AppCompatActivity {
public static final String TAG = MainActivity.class.getSimpleName();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String apiKey = "9e64526f3fcfdfc5b4461b124ab998ea";
double latitude = 9999;//37.8267 ;
double longitude = 122.4233 ;
String forecastUrl = "https://api.darksky.net/forecast/" + apiKey + "/" + latitude + "," + longitude;
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder().url(forecastUrl).build();
Call call = client.newCall(request);
call.enqueue(new Callback() {
@Override
public void onFailure(Call call, IOException e) {
}
@Override
public void onResponse(Call call, Response response) throws IOException {
try {
Log.v(TAG, response.body().string());
if (response.isSuccessful()) {
else {
alertUserAboutError();
}
}
} catch (IOException e) {
Log.e(TAG, "Exception caught : ", e);
}
}
});
}
private void alertUserAboutError() {
AlertDialogFragment dialog = new AlertDialogFragment();
dialog.show(getFragmentManager(), "Error_Dialogue");
}
;
}
This is my AlertDialogFragment code
package com.teamrandom.stormy;
import android.app.AlertDialog;
import android.app.Dialog;
import android.app.DialogFragment;
import android.content.Context;
import android.os.Bundle;
public class AlertDialogFragment extends DialogFragment {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Context context = getActivity();
AlertDialog.Builder builder = new AlertDialog.Builder(context);
.setTitle(context.getString(R.string.Error_Title))
.setMessage(getString(R.string.Error_Message))
.setPositiveButton(getString(R.string.error_ok_button_text), null);
AlertDialog dialog = builder.create();
return dialog;
}
}
//The error is here. It sais it is an else without an if. This is in the MainActivity
if (response.isSuccessful()) {
else {
alertUserAboutError();
// Here the error sais 'Cannot resolve method'
.setTitle(context.getString(R.string.Error_Title))
.setMessage(getString(R.string.Error_Message))
.setPositiveButton(getString(R.string.error_ok_button_text), null);

448 PointsI managed to solve the error that sais cannot resolve method.
Just change this snippet of code
.setTitle(context.getString(R.string.Error_Title))
.setMessage(getString(R.string.Error_Message))
.setPositiveButton(getString(R.string.error_ok_button_text), null);
To this
builder.setTitle(R.string.Error_title)
.setMessage(R.string.Error_message)
.setPositiveButton(R.string.Error_ok_button_text, null);

2,027 PointsYour if statement is not closed. When you make an if statement, you must open it with a { and close it with a }.
E.g.
´´´java if(myCondition) { System.out.println("True!"); } else { System.out.println("Not true :("); } ´´´

264 PointsIf you want to chain the methods you shouldn´t put the semicolon when creating the AlertDialogFragment object.
AlertDialog.Builder builder = new AlertDialog.Builder(context)
.setTitle(context.getString(R.string.Error_Title))
.setMessage(getString(R.string.Error_Message))
.setPositiveButton(getString(R.string.error_ok_button_text), null);
That semicolon was causing the problem
