Parsing JSON data and storing into a listview

Parsing JSON data and storing into a listview - android

I'm currently developing a small android weather app. That passes through 3 strings to display three weather elements from the open source weatherAPI. I'm trying to display this in a listview. I got it working when passing in 1 string. But I'm having trouble passing in multiple strings. Any advice would be appreciated
ArrayList<Weather> weatherData = new ArrayList<Weather>();
private ListView listView1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView1 = (ListView) findViewById(R.id.listView1);
String[] city = {
new String("dublin,ire"),
new String("London,uk")
};
for (int i = 0; i < city.length; ++i) {
listView1.add(city[i]);
}
//String city2 = "Dublin,ire";
Button button1 = (Button)findViewById(R.id.button1);
button1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
setContentView(R.layout.activity_main);
Button button1 = (Button) findViewById(R.id.button1);
Log.d("MR.bool", "Button1 was clicked ");
startActivity(new Intent(MainActivity.this, WebViewActivity.class));
}
});
cityText = (TextView) findViewById(R.id.cityText);
condDescr = (TextView) findViewById(R.id.condDescr);
temp = (TextView) findViewById(R.id.temp);
hum = (TextView) findViewById(R.id.hum);
press = (TextView) findViewById(R.id.press);
windSpeed = (TextView) findViewById(R.id.windSpeed);
windDeg = (TextView) findViewById(R.id.windDeg);
imgView = (ImageView) findViewById(R.id.condIcon);
imgView2 = (ImageView) findViewById(R.id.imageView1);
JSONWeatherTask task = new JSONWeatherTask();
task.execute(new String[]{city});
if (city.contains("uk")) {
imgView2.setImageResource(R.drawable.uk);
} else if (city.contains("ire")) {
imgView2.setImageResource(R.drawable.ireland);
} else if (city.contains("de")) {
imgView2.setImageResource(R.drawable.germany);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
private class JSONWeatherTask extends AsyncTask<String, Void, Weather> {
#Override
protected Weather doInBackground(String... params) {
Weather weather = new Weather();
String data = ((new WeatherHttpClient()).getWeatherData(params[0]));
try {
weather = JSONWeatherParser.getWeather(data);
// Let's retrieve the icon
weather.iconData = ((new WeatherHttpClient()).getImage(weather.currentCondition.getIcon()));
} catch (JSONException e) {
e.printStackTrace();
}
return weather;
}
#Override
protected void onPostExecute(Weather weather) {
super.onPostExecute(weather);
if (weather.iconData != null && weather.iconData.length > 0) {
Bitmap img = BitmapFactory.decodeByteArray(weather.iconData, 0, weather.iconData.length);
imgView.setImageBitmap(img);
}
else if(weatherData.size() > 0)
{
ArrayAdapter<Weather> adapter = new ArrayAdapter<Weather>(MainActivity.this,
android.R.layout.activity_list_item, weatherData);
listView1.setAdapter(adapter);
// here you can also define your custom adapter and set it to listView
//according to your own defined layout as items
}
cityText.setText(weather.location.getCity() + "," + weather.location.getCountry());
condDescr.setText(weather.currentCondition.getCondition() + "(" + weather.currentCondition.getDescr() + ")");
temp.setText("" + Math.round((weather.temperature.getTemp() - 273.15)) + "�C");
hum.setText("" + weather.currentCondition.getHumidity() + "%");
press.setText("" + weather.currentCondition.getPressure() + " hPa");
windSpeed.setText("" + weather.wind.getSpeed() + " mps");
windDeg.setText("" + weather.wind.getDeg() + "�");
}
}
}

You can use Gson to parse the json.
I'm assuming that you are receiving a jsonArray. So, you can do something like this:
ArrayList<Weather> weatherArrayList = new ArrayList<Weather>();
Gson gson = new Gson();
JsonParser jsonParser = new JsonParser();
JsonArray jArray = jsonParser.parse(responseStr).getAsJsonArray();
for (JsonElement obj : jArray) {
Weather weatherModel = gson.fromJson(response, Weather.class);
weatherArrayList.add(weatherModel);
}
The code above parse the data in your json and adds them into your "weatherArrayList" this ArrayList you should place it in your adapter and just set in your listview.
This might be your custom adapter
public class WeatherAdapter extends ArrayAdapter<Weather> {
public WeatherAdapter(Context context) {
super(context, 0);
}
#Override
public View getView(int position, View convertView, ViewGroup parent){
// here you should set up the custom view. That is the view of each Item of your ListView
}
}
I hope I helped you :)

How to display name in spinner dynamically from server

Hi Now I'm retrieving data to spinner dynamically, but now it displaying some id's but those Id details are stored in other table, I want display those details in the spinner instead of id. And if I select particular product in spinner according that product details should display in list.
I'm using Retrofit method for retrieving data from server
package cfirst.live.com.activity;
public class Pos_outlet extends AppCompatActivity implements RestCallback,View.OnClickListener{
Spinner spinner;
ArrayList<String> products;
String numberAsString, product_name;
int i;
private int cartProductNumber = 0;
String[] items;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.pos_outlet);
sharedPreference = new MySharedPreference(Pos_outlet.this);
GsonBuilder builder = new GsonBuilder();
gson = builder.create();
initViews();
}
private void initViews() {
row1 =(TableRow)findViewById(R.id.row1);
spinner=(Spinner)findViewById(R.id.spinner);
POSStoreID = (TextView) findViewById(R.id.POSStoreID);
POSLocationID = (TextView) findViewById(R.id.POSLocationID);
Intent intent = getIntent();
id = intent.getStringExtra("id");
index_id= intent.getStringExtra("index_id");
callStoreDetaislsAPI();
callSmbProductsAPI();
getProductAPI();
}
// **Using this api I'm setting id'd to spinner**
private void getProductAPI() {
HashMap<String, String> map = new HashMap<String, String>();
map.put("store", index_id);
Toast.makeText(getApplicationContext(),index_id, Toast.LENGTH_LONG).show();
RestService.getInstance(Pos_outlet.this).getproductlist(map, new MyCallback<List<PosmultistoresModel>>(Pos_outlet.this,
Pos_outlet.this, true, "Finding products....", GlobalVariables.SERVICE_MODE.GET_PRODUCTS));
}
// **this API have product Id's Details**
private void callSmbProductsAPI() {
HashMap<String, String> map = new HashMap<String, String>();
map.put("index_id", product);
//Toast.makeText(getApplicationContext(),added_by, Toast.LENGTH_LONG).show();
RestService.getInstance(Pos_outlet.this).getSmbProduct(map, new MyCallback<List<PosSmbProductModel>>(Pos_outlet.this,
Pos_outlet.this, true, "Fetching details....", GlobalVariables.SERVICE_MODE.SMB_PRODUCT));
}
#Override
public void onClick(View v) {
switch(v.getId()) {
case R.id.AddtoBasket:
callPosProductsAPI();
callSmbProductsAPI();
break;
}
}
#Override
public void onFailure(Call call, Throwable t, GlobalVariables.SERVICE_MODE mode) {
//Toast.makeText(getApplication(),"failure",Toast.LENGTH_LONG).show();
}
#Override
public void onSuccess(Response response, GlobalVariables.SERVICE_MODE mode) {
switch (mode) {
//** I'm setting data to spinner **
case GET_PRODUCTS:
try {
List<PosmultistoresModel> businessgroups = (List<PosmultistoresModel>) response.body();
product_name = businessgroups.get(0).getProduct();
List<PosmultistoresModel> list=null;
for(i=0;i<businessgroups.size();i++)
{
list=businessgroups;
}
items = new String[list.size()];
for(int i=0; i<businessgroups.size(); i++){
//Storing names to string array
items[i] = list.get(i).getProduct();
}
ArrayAdapter<String> adapter1;
adapter1 = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_spinner_dropdown_item, items);
//setting adapter to spinner
spinner.setAdapter(adapter1);
} catch (Exception e) {
e.printStackTrace();
}
break;**
// ** Product id details (title, image, etc) Api
case SMB_PRODUCT:
try {
ArrayList<PosSmbProductModel> products = (ArrayList<PosSmbProductModel>) response.body();
//Product_id = products.get(0).getProduct();
// for (int i = 0; i < products(); i++) {
Title = products.get(0).getTitle();
productname1.setText(Title);
imageid12 = products.get(0).getMain_image();
Picasso.with(this).load("https://www.consumer1st.in/pre_production/uploads/" + imageid12).into(imageid1);
}
// }
catch(Exception e)
{
e.printStackTrace();
}
break;
}
}
}

I am assuming that your product_name = businessgroups.get(0).getProduct(); is getting a pruduct.
First of all please remove this part
product_name = businessgroups.get(0).getProduct();
List<PosmultistoresModel> list=null;
for(i=0;i<businessgroups.size();i++)
{
list=businessgroups;
}
items = new String[list.size()];
for(int i=0; i<businessgroups.size(); i++){
//Storing names to string array
items[i] = list.get(i).getProduct();
}
then can you try
ArrayList<String> productList = new ArrayList<>();
for (int i = 0; i < businessgroups.size(); i++) {
productList.add(businessgroups.get(i).getProduct());
}
And finally
adapter1 = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_spinner_dropdown_item, productList);

Return button to previous activity with BaseAdapter

I currently have two activities doing HTTP requests.
The first activity contains a CustomList class extends BaseAdapter.
On the second, there is a previous button allowing me to return to the first activity.
Returning to the first activity, I would like to be able to recover the state in which I left it. That is to say to be able to find the information which also come from an HTTP request. I would like to find the data "infos_user" which is in the first activity and all the data in the BaseAdapter.
My architecture is as follows: Activity 0 (HTTP request) -> Activity 1 (with BaseAdapter and HTTP request) -> Activity 2 (HTTP request)
I put all the code because I really don't know how can I do this :/

Thanks for your help.

if you want to maintain GetChildrenList state as it is then just call finish() rather than new intent on previous button click as follow
replace in GetLearningGoalsList
#Override
public void onClick(View v) {
Intent myIntent = new Intent(GetLearningGoalsList.this, GetChildrenList.class);
myIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(myIntent);
return;
}
with
#Override
public void onClick(View v) {
finish();
}

Remove an item from view inside an adapter

I am trying to remove an item from view when its flag become 4. I tried mObjects.remove(position) and then notifyDataSetChanged(). but it didn't worked.we tried all the following
if (getItem(position).getFlag().trim().equalsIgnoreCase("4")) {
remove(position);
adapter.notifyDataSetChanged();
matcheslistview.setAdapter(adapter);
also this one
// mObjects.remove(position)
// notifyDataSetChanged();
and this one
// mObjects.remove(position);
//remove(position);
//mainObjects.remove(position);
//notifyDataSetChanged();
and this one
// Object toRemove = adapter.getItem(position);
// mObjects.remove(toRemove);
// mObjects.clear();
and all the time we got java.lang.IndexOutOfBoundsException: Invalid index 1, size is 0.Here is the complete adapter class

Don't remove the object in getview, if you have to filter it, filter it before sending out to adapter. May be possible that while creating the child view the 1st cell has tag "4" now the view didn't create(since return was not called) but you are trying to remove its position, so it will definitely give you IndexOutOfBoundsException.
My best solution would be, set the adapter with
new ArrayList<LikeMatcheddataForListview>()
whenever you start the screen. Once your AsyncTask completes filter out the child with tags "4"(better filter it out in the asynctask only, less task in ui thread) then refresh the adapter, like
public void refresh(ArrayList<LikeMatcheddataForListview>() arrObjects){
objects = arrObjects;
notifyDataSetChanged();
}
Check it out, it should do the trick

Please try following
Your code
if (getItem(position).getFlag().trim().equalsIgnoreCase("4")) {
mObjects.remove(position);
adapter.notifyDataSetChanged();
matcheslistview.setAdapter(adapter);
}
TO
do not set adapter again to list view
if (getItem(position).getFlag().trim().equalsIgnoreCase("4")) {
mObjects.remove(position);
notifyDataSetChanged();
}

This may not be correct approach to remove the item form listview.
Whenever your adapter data is getting changed then just check if that flag matches your string i.e. "4" in each item and remove the respective item from the list and just call notifyItemRemoved with position insted of notifyDataSetChanged

can't show the thumbnail from youtube?

this app should show thumbnail , title, and the duration of each video in the playlist selected , but thumbnail remain white
the application works but It don't show the thumbnail of the video in the playlist
how can I do ? you have any solution?
THIS IS MY CODE
public class MainActivity extends Activity {

Use Picasso to set the image url like so:
Picasso.withContext(this).load(thumbnailUrl).into(myImageView);
To do this you'll need to return the JSON object in the doInBackground method, or use something like Retrofit (as I mentioned in the comment above) to get a nice POJO and return that. Then in the postExecute you can use the thumbnail url in the JSON (or POJO) and set it using Picasso above. Picasso will take care of downloading and caching the image for you and loading it into the image view.

On Click Of Tabs(Radio Button) My Memory Getting Double

My layout is very complex. I have to make full page scrollable so what i did is - i have a gridView adapter for my gridview items and one custom adapter which has four tabs and then i set my gridview in that custom adapter. Then this whole view is set on my main activity which has a listview so its now scrolling with full page but issue is with memory.
I have 4 tab click events on custom adapter from which i am sending those click events through put extra to main activity where i have four web service and a condition that if 1st tab is selected then 1st web service call will occur and new adapter will set on main activity.
problem: when i click on 1st tab my memory size is 130 MB and on click of 2nd tab it raises to double so and same thing is happen when i click on 3rd tab. I am using lazy loading for loading my images which also maintains my caching, i have tried clear(), notifyDataSetChanged() but doesn't make any change. My memory is increasing on each click of tabs.
Here is my code:

The description you showed is indicating a possible memory leak. Check my answer for this question. My guess is that you should use the Application context instead of the Activity context in your code. Use the video in the answer mentioned to know how to identify the leak.
