Android Build a Weather App (2015) Concurrency and Error Handling Configuring the Alert Dialog

3,311 Points

In the Alert Dialog my [OK] button is set in the middle of the dialog. But in the lesson its in the bottom right?

How do I fix it so it would be set in the bottom right like in the tutorial?

Here is my source code:


package com.teamtreehouse.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 {

    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Context context = getActivity();
        AlertDialog.Builder builder = new AlertDialog.Builder(context)
                .setTitle(context.getString(R.string.error_title)) //change all the text messages to String resources. Steps: 1. Alt+Enter. 2. give the resource a name 3. then hit ESC key when CONTEXT is highlighted in red.
                .setPositiveButton(context.getString(R.string.error_ok_button_text), null);
    AlertDialog dialog  = builder.create();
        return dialog;


package com.teamtreehouse.stormy;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;

import com.squareup.okhttp.Call;
import com.squareup.okhttp.Callback;
import com.squareup.okhttp.OkHttpClient;
import com.squareup.okhttp.Request;
import com.squareup.okhttp.Response;

import java.io.IOException;

public class MainActivity extends ActionBarActivity {

    public static final String TAG= MainActivity.class.getSimpleName();

    protected void onCreate(Bundle savedInstanceState) {

        String apiKey = "d5faf0cb201f103df4dde0b8b0a4f490";
        double latitude = 9999; //37.8267;
        double longitude = -122.423;
        String forecastUrl = "https://api.forecast.io/forecast/d5faf0cb201f103df4dde0b8b0a4f490/," + apiKey +
                "/" + latitude +"/" + "," + longitude;

        OkHttpClient client = new OkHttpClient();
        Request request = new Request.Builder().url(forecastUrl).build();

        Call call = client.newCall(request);
        call.enqueue(new Callback() {
            public void onFailure(Request request, IOException e) {


            public void onResponse(Response response) throws IOException {
                try { Log.v(TAG, response.body().string()); //

                    if (response.isSuccessful()){
                    else {
                } catch (IOException e) {
                    Log.e(TAG, "Exception caught: ", e);


        Log.d(TAG, "Main UI code is running!");

// the new stuff:
    private void alertUserAboutError() { //visually alert the user that an error has occurred. //we could use toast message but the user may miss it as it disappears quickly // instead use dialogs that requires users to confirm to dismiss
        AlertDialogFragment dialog = new AlertDialogFragment(); //from AlertDialogFragment.java

        // To show the dialog in the activity
        // (we need a few parameters in here), the first is 'fragment manager',
        // fortunately, we can just call 'getFragmentManager()', we don't have to set up one, its already theire for us.
        // and the second parameter is a tag for the dialog.
        // this is just a string tag we can use to refer to it. We can name it anything. but in this case we'll name it 'error_dialog'
        dialog.show(getFragmentManager(), "error_dialog");

Found the error:

        double latitude = 9999; //37.8267;

I forgot to delete the '9999' we purposely made in the tutorial to get the error and uncomment out 37.8267

should be like this:

        double latitude = 37.8267;
