android json add hyperlink to text

android json add hyperlink to text - java

Here is my json output sample:
{"podcast":[{"link":"rtsp:\\live.xxx.ro:554\vod\_definst_\mp4:05\rfm_00.mp4","name":"Recording 1"}
For parsing the json code i use this:
private static final String TAG_LINK = "link";
private static final String TAG_NAME = "name";
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
products = json.getJSONArray(TAG_PRODUCTS);
for (int i = 0; i < products.length(); i++) {
JSONObject c = products.getJSONObject(i);
String link = c.getString(TAG_LINK);
String name = c.getString(TAG_NAME);
HashMap<String, String> map = new HashMap<String, String>();
map.put(TAG_LINK, link);
map.put(TAG_NAME, name);
productsList.add(map);
}
} else {
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
protected void onPostExecute(String file_url) {
pDialog.dismiss();
runOnUiThread(new Runnable() {
public void run() {
ListAdapter adapter = new SimpleAdapter(
PodCast.this, productsList,
R.layout.list_item, new String[] {
TAG_NAME, TAG_LINK },
new int[] { R.id.link, R.id.name });
setListAdapter(adapter);
}
});
For the layout this is the code of the link view:
<TextView
android:id="#+id/name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingTop="6dip"
android:paddingLeft="6dip"
android:paddingBottom="6dip"
android:textSize="17dip"
android:autoLink="web"
android:textColor="#fff"
android:textColorLink="#fff"
android:textStyle="bold"/>
All works well...but in the link view i get the whole link rtsp://live.xxx.ro...etc and i would like to be something like this: NAME So i would have the name and when i click it to open the specified link. Can you guys please help me figure it out how?

Simple...
String href = String.format(" %s ", map.get(TAG_LINK), map.get(TAG_NAME));
textV.setText(Html.fromHTML(href))
Or if you have a link as a resource string; just make sure that the reserved HTML characters aren't converted to HTML entities.
An example that would parse incorrectly:
<string name="a_link"><a href="http://www.google.com">click here</a></string>
To fix it, edit strings.xml manually and convert HTML entities to characters they represent,
so that the above becomes:
<string name="a_link">click here</string>
And it should work.

You need to set a function setOnItemClickListener() and inside it declare something like this:
Uri uri = Uri.parse( "http://www.google.com" );
startActivity( new Intent( Intent.ACTION_VIEW, uri ) );

I have debugged and check Logcat and see that data has loaded and everything normal, but don't know why data can not load to ListView
updated

How to fix this problem?? thank you

You're not providing your list to the list view. You need to add your list to your list view with an adapter. This tutorial should help walk you through the process. http://www.vogella.com/tutorials/AndroidListView/article.html
In your postExecute of your asyncTask you can than call adapter.notifyDataSetChanged(). And your view will update with the new list content.

This code looks really similar... maybe copy the rest of it?
You need an Adapter for your data.
protected void onPostExecute(String result) {
// dismiss the dialog after getting all tracks
pDialog.dismiss();
ListAdapter adapter = new ArrayAdapter<Category>(
CategoryCarActivity.this, // the context
android.R.layout.simple_list_item_1, // Simple list item - will toString() your data
carList // The arraylist
);
// updating listview
setListAdapter(adapter);
}
You can also make a subclass of ArrayAdapter<Category> if you really want to customize a layout.

Adding to Ben's answer, you need to set the list to the listview adapter after the asynctask completes its background functionality i.e in onPostExecute() method of the asynctask.

Need to set the list view as suggested by Ben in onPostExecute().
ListView listView = (ListView) findViewById(R.id.your_list_view_id);
listView.getAdapter().notifyDataSetChanged();

unable to retrieve complete webpage using jsoup, possible fix? [duplicate]

im trying to parse url generated by Bootstrap`s Bootpage.js which looks like
https://example.com/#page-2
but JSOUP cant parse it and showing main url.
how to get normal link from Bootpage or how to make JSOUP to parse it.
Parsing code:
Jsoup.connect("https://example.com/#page-2").followRedirects(true).get();

(See UPDATE below, first/accepted solution didn't met the android requirement, but is left for reference.)
Desktop Solution
HtmlUnit doesn't seem able to handle this site (often the case, lately). So I don't have a plain java solution either, but you could use PhantomJS: download the binary for your os, create a script file, start the process from within your java code and parse the output with a dom parser like jsoup.
Script file (here called simple.js):
var page = require('webpage').create();
var fs = require('fs');
var system = require('system');
var url = "";
var fileName = "output";
// first parameter: url
// second parameter: filename for output
console.log("args length: " + system.args.length);
if (system.args.length > 1) {
url=system.args[1];
}
if (system.args.length > 2){
fileName=system.args[2];
}
if(url===""){
phantom.exit();
}
page.settings.userAgent = 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.120 Safari/537.36';
page.settings.loadImages = false;
page.open(url, function(status) {
console.log("Status: " + status);
if(status === "success") {
var path = fileName+'.html';
fs.write(path, page.content, 'w');
}
phantom.exit();
});
Java code (example to get title and cover-url):
try {
//change path to phantomjs binary and your script file
String outputFileName = "srulad";
String phantomJSPath = "phantomjs" + File.separator + "bin" + File.separator + "phantomjs";
String scriptFile = "simple.js";
String urlParameter = "http://srulad.com/#page-2";
new File(outputFileName+".html").delete();
Process process = Runtime.getRuntime().exec(phantomJSPath + " " + scriptFile + " " + urlParameter + " " + outputFileName);
process.waitFor();
Document doc = Jsoup.parse(new File(outputFileName + ".html"),"UTF-8"); // output.html is created by phantom.js, same path as page.js
Elements elements = doc.select("#list_page-2 > div");
for (Element element : elements) {
System.out.println(element.select("div.l-description.float-left > div:nth-child(1) > a").first().attr("title"));
System.out.println(element.select("div.l-image.float-left > a > img.lazy").first().attr("data-original"));
}
} catch (IOException | InterruptedException e) {
e.printStackTrace();
}

UPDATE
Parsing of websites with javascript based dynamic content in Android is possible using WebView and jsoup.
The following example app uses a javascript enabled WebView to render a Javascript dependent website. With a JavascriptInterface the html source is returned, parsed with jsoup and as a proof of concept the titles and the urls to the cover-images are used to populate a ListView. The buttons decrement or increment the page number triggering an update of the ListView. Note: tested on an Android 5.1.1/API 22 device.

How do I make separators for a ListView with a SimpleAdapter

I'm new to the java programming language and I'm trying to build an app. The app has to make a list of worked hours that have been saved in an MySQL database. I found an example app, that helped me retrieving the data from the database and putting it in a ListView.
But now we get to my problem. I want to put separators in the listview.
Now, the date of the worked hours is in every item of the ListView. I want the date only above the first item.
I've searched the internet for a way to do this, but it didn't help me.
This it the code that gets the data and puts it in a ListView:
public class AllUrenActivity extends ListActivity {
String url_all_uren;
String ip;
String proid;
String uid = MainScreenActivity.uid;
String datum;
String datum1;

</LinearLayout>
What is the best way to get the date separators? Thank you.

Add this at the end of list_uren.xml before closing the LinearLayout
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#666666" />
You can change the background to whatever you want.

How to use intent to call the method of next activity in android

What i am doing now is--> i'm getting data from the webservice in one activity and displaying the entire data in a listview. i added just a search functinality on the presented listview itself.
My requirement is --> i should have a search button in the first activity. When it is clicked, should show the related result in second activity, to do this added putExtras in the intent like this intent.putExtra("search", searchBox); that is the second activities search function keyword. but still m not getting the searched output.

}
}

Intents are for activity and not methods inside them , So you cannot use it to call any specific method however you can use extras to figure out what you want to do \
like after when you get extras from Intent you can ,
if extras has "search" value
then do something about it

Fatal exception caused by android.os.NetworkOnMainThreadException

As I am a beginner to Android programming, I was trying to run some tutorials, but upon running the programs( the source code is available here: http://www.androidhive.info/2012/01/android-json-parsing-tutorial/ ) I got an error.
The program is supposed to read in data from a website and process it, but I think there is something wrong with the networking part.
I am fully aware there have been similar questions here on SO, yet I had no clue how to solve it, perhaps anyone could give solutions which I also can understand.
Strange NetworkOnMainThreadException in Android app?
This is a questions which was asked earlier and is identical to my problem, but I had no clue what they are trying to say there, i.e. "To fix you just need to move any thing that is touching the network to its own thread." makes no sense to me whatsoever..
Can anyone please shed some light on this?

Use an AsyncTask to move your network operation off of the main/ui thread and onto a background/worker thread.
Expanding on the example from the tutorial, wrap the JSON stuff inside of an anonymous AsyncTask:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
new AsyncTask<Void, Void, JSONObject>() {
protected JSONObject doInBackground(Void... args) {
// Creating JSON Parser instance
JSONParser jParser = new JSONParser();
// getting JSON string from URL
return jParser.getJSONFromUrl(url);
}
protected void onPostExecute(JSONObject json) {
// Hashmap for ListView
ArrayList<HashMap<String, String>> contactList = new ArrayList<HashMap<String, String>>();
try {
// Getting Array of Contacts
contacts = json.getJSONArray(TAG_CONTACTS);
// looping through All Contacts
for(int i = 0; i < contacts.length(); i++){
JSONObject c = contacts.getJSONObject(i);
// Storing each json item in variable
String id = c.getString(TAG_ID);
String name = c.getString(TAG_NAME);
String email = c.getString(TAG_EMAIL);
String address = c.getString(TAG_ADDRESS);
String gender = c.getString(TAG_GENDER);
// Phone number is agin JSON Object
JSONObject phone = c.getJSONObject(TAG_PHONE);
String mobile = phone.getString(TAG_PHONE_MOBILE);
String home = phone.getString(TAG_PHONE_HOME);
String office = phone.getString(TAG_PHONE_OFFICE);
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(TAG_ID, id);
map.put(TAG_NAME, name);
map.put(TAG_EMAIL, email);
map.put(TAG_PHONE_MOBILE, mobile);
// adding HashList to ArrayList
contactList.add(map);
}
} catch (JSONException e) {
e.printStackTrace();
}
/**
* Updating parsed JSON data into ListView
* */
ListAdapter adapter = new SimpleAdapter(this, contactList,
R.layout.list_item,
new String[] { TAG_NAME, TAG_EMAIL, TAG_PHONE_MOBILE }, new int[] {
R.id.name, R.id.email, R.id.mobile });
setListAdapter(adapter);
// selecting single ListView item
ListView lv = getListView();
// Launching new screen on Selecting Single ListItem
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// getting values from selected ListItem
String name = ((TextView) view.findViewById(R.id.name)).getText().toString();
String cost = ((TextView) view.findViewById(R.id.email)).getText().toString();
String description = ((TextView) view.findViewById(R.id.mobile)).getText().toString();
// Starting new intent
Intent in = new Intent(getApplicationContext(), SingleMenuItemActivity.class);
in.putExtra(TAG_NAME, name);

}
});
}
}.execute((Void) null);
}

android json add hyperlink to text - java

You need to set a function setOnItemClickListener() and inside it declare something like this: Uri uri = Uri.parse( "http://www.google.com" ); startActivity( new Intent( Intent.ACTION_VIEW, uri ) );
