Answer ref

make a file fetchData.java
import android.os.AsyncTask;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
public class fetchData extends AsyncTask<Void,Void,Void> {
String data ="";
String dataParsed = "";
String singleParsed ="";
#Override
protected Void doInBackground(Void... voids) {
try {
URL url = new URL("https://api.myjson.com/bins/107msz");
HttpURLConnection httpURLConnection = (HttpURLConnection)
url.openConnection();
InputStream inputStream = httpURLConnection.getInputStream();
BufferedReader bufferedReader = new BufferedReader(new
InputStreamReader(inputStream));
String line = "";
while(line != null){
line = bufferedReader.readLine();
data = data + line;
}
JSONArray JA = new JSONArray(data);
for(int i =0 ;i <JA.length(); i++){
JSONObject JO = (JSONObject) JA.get(i);
singleParsed = "Name:" + JO.get("name") + "\n"+
"Password:" + JO.get("password") + "\n";
dataParsed = dataParsed + singleParsed +"\n" ;
}
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(Void aVoid) {
super.onPostExecute(aVoid);
MainActivity.data.setText(this.dataParsed);
}
}
Another file MainActivity.java
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
Button click;
public static TextView data;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
click = (Button) findViewById(R.id.button);
data = (TextView) findViewById(R.id.fetcheddata);
click.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
fetchData process = new fetchData();
process.execute();
}
});
}
}
In your Activity_main.xml write this code
<?xml version="1.0" encoding="utf-8"?>

Assigning a string to a text value in an async task called from AppWidgetProvider

I am trying to set a textview value in a widget via an async task. I created a simple widget whose layout looks like this:
widget_test.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="#drawable/widget_bg_normal"
>
<TextView
android:id="#+id/widget_tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="testing 123"
android:layout_gravity="center_horizontal|center"
android:layout_marginTop="5dip"
android:padding="10dip"
android:textColor="#android:color/black"
>
</TextView>
</LinearLayout>
My AppWidgetProvider code is:
package com.example.beerportfoliopro;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.Context;
/**
* Created by Mike on 12/26/13.
*/
public class HelloWidget extends AppWidgetProvider {
#Override
public void onEnabled(Context context){
//build url for async task
String url = "hiddenURL";
//call async task
new GetRandomBeer(context).execute(url);
}
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds){
//todo: call update code, which should be the same as onEnabled
}
}
This above code should control what happens when the app is enabled (aka when user adds the app to their home screen) and what the app should do when it updates itself based on the time set in my hello_widget-provider.xml here:
<?xml version="1.0" encoding="utf-8"?>
<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"
android:minWidth="146dip"
android:minHeight="72dip"
android:updatePeriodMillis="1000"
android:initialLayout="#layout/widget_test"
>
</appwidget-provider>
For testing purposes I am not having my asynctask parse any json yet I am just trying to change the value of the text on my widget via the async task. Here is the code for my async task:

}
protected void onPostExecute(String result){
Log.d("taste","Inside get taste");
//decode json here
try{
//todo: get all beer data
//todo: set text views with data

}
catch(Exception e){
}
}

try {

StatusLine statusLine = response.getStatusLine();
int statusCode = statusLine.getStatusCode();
if (statusCode == 200) {
HttpEntity entity = response.getEntity();
InputStream inputStream = entity.getContent();
BufferedReader reader = new BufferedReader(
new InputStreamReader(inputStream));
String line;
while ((line = reader.readLine()) != null) {
stringBuilder.append(line);
}
inputStream.close();
} else {

}

}
return stringBuilder.toString();
}
}
My problem right now is that right now my widget_tv is showing the error:
cannot resolve symbol widget_tv

Your TextView ID should be: R.id.widget_tv not R.widget_tv

have you called setContentView(view) in the activity class that you are passing to the asynctask before executing the asynctask? if not you should use the layout inflater to inflate the textview
((Activity) c).getLayoutInflater().inflate(R.id.widget_tv, null);

Download images from remote URLs

Currently I am developing an Android app containing a list view which displays links for Youtube videos. The application gets its data from the server as JSON. Now I am trying to display thumbnails for these video from this subdomain - http://img.youtube.com/vi/.

You can use UniversalImageLoader
it very simple for using -imageLoader.displayImage(imageUri, imageView);

Downloading images and then displaying in ListView is bad process. Because just think if you are having >100 images then it will take more time to display it.
And now optimization which i would suggest is: Implement logic for lazy loading of Images inside ListView.
Refer below examples:
Lazy List by Fedor
Universal Image Loader
ImageLoader by Novoda

In youtube JSON data ,The entire videos information will be in "entry" JSON array. You are creating same tag name for all the entires in the Hashmap.. If you give same tag for all entries then it will display last entry image. Please change the TAG NAME to "map.put(CA_IMG+i, ca_link + ".jpg");"
I hope this solution will be helpful for you.

change background color or text color before clicking in listview, dynamically using json

Can anyone tell me how to change the background color or text color of each row displayed based on the data dynamically.I have modified the example/SourceCode which I got online,will paste the code below.
Change Backgroundcolor of row to Blue if magnitude > 8.5
or
Change Backgroundcolor of Text to Blue if magnitude > 8.5
Note:Color should change, Before Clicking on the list.
Thanks a lot I appreciate the help.

You need to override the setViewBinder() method of your Adapter. Check this link.
Try the following code and let me know:
SimpleAdapter adapter = new SimpleAdapter(this, mylist , R.layout.main,
new String[] { "name", "magnitude" },
new int[] { R.id.item_title, R.id.item_subtitle });
adapter.setViewBinder(new SimpleAdapter.ViewBinder() {
#Override
public boolean setViewValue(View view, Object data,
String textRepresentation) {
int v=view.getId();
if(v==R.id.item_subtitle && Float.valueOf(data.toString())>8.5){
((View) view.getParent()).setBackgroundColor(Color.BLUE);
}
TextView TV=(TextView) view;
TV.setText(data.toString());
return true;
}
});
setListAdapter(adapter);

SimpleAdapter is for static data. If you want to optimize it you'd better off create your own custom adapter.
