Converting HTML escape sequence to Java

I am receiving a string using REST APIs.
JSONObject obj = new JSONObject(output);
JSONArray contacts = obj.getJSONArray("results");
JSONObject result = contacts.getJSONObject(0);
..
String brandName = result.getString("productName");
In some cases productName comes as Dri-FIT™ Element Half Zip.
I want to show it as "Dri-FIT™ Element Half Zip" in Android, but it shows up in the TextView as Dri-FIT™ Element Half Zip.
Can anyone help me as to how to convert the HTML escape sequence to a valid Java escape sequence so that I can view it?

You can try this. I think this is the best way to show your special symbol.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
tv.setText(Html.fromHtml("Dri-FIT™ Element Half Zip", Html.FROM_HTML_MODE_COMPACT));
}else{
tv.setText(Html.fromHtml("Dri-FIT™ Element Half Zip"));
}

Please replace &#8482 to \u2122 (2122 is hex for 8482)

How to catch a View with Tag by Espresso in Android?

I have a PinCodeView that extends LinearLayout. I have following code in my init() method. DigitEditText extends EditText and just accepts one digit. This view will be used to receive confirmation code which has 4 digits long.
private void init()
{
...
for (int i = 0; i < 4; i++)
{
DigitEditText digitView = getDigitInput();
digitView.setTag(R.id.etPinCodeView, i); // uses for Espresso testing
digitView.setKeyEventCallback(this);
...
}
I have created res/values/ids.xml and this is its content:
<resources>
<item name="etPinCodeView" type="id"/>
</resources>
Now, in Espresso I want to catch each DigitEditText and put a digit in it. How I'm able to do that? I see there are two methodes, withTagKey() and withTagValue() but I have no idea how to get them into work.
I thought something like this might work but seems I'm not able to assign 0 into withTagValue().
onView(allOf(withTagKey(R.id.etPinCodeView), withTagValue(matches(0)))).perform(typeText("2"));

Since withTagValue needs an instance of org.hamcrest.Matcher as an argument, we can create a simple one using the Matcher.is method
to find views with a certain tag in your expresso test:
String tagValue = "lorem impsum";
ViewInteraction viewWithTagVI = onView(withTagValue(is((Object) tagValue)));

After setting the tag in your view somewhere in the app, for those confused about the syntax in Kotlin:
withTagValue(`is`(EXPECTED_TAG))
The complete syntax to assert a tag on a specific view:
onView(
allOf(
withId(R.id.some_id),
withTagValue(`is`(EXPECTED_TAG))
)
)
Simple :)

I solved my problem with this trick. Hope it saves some times for you.
First I used Id rather than tag.
for (int i = 0; i < 4; i++)
{
DigitEditText digitView = getDigitInput();
digitView.setId(R.id.etPinCodeView + i); // uses for Espresso testing
digitView.setKeyEventCallback(this);
...
And this is test for it:
onView(withId(R.id.etPinCodeView + 0)).perform(typeText("2"));
onView(withId(R.id.etPinCodeView + 1)).perform(typeText("0"));
onView(withId(R.id.etPinCodeView + 2)).perform(typeText("1"));
onView(withId(R.id.etPinCodeView + 3)).perform(typeText("6"));

How to get text out of TextView or ListView Android?

I have a ListView. This ListView load this text/data from a URL/HTML code on a webpage. I use a for loop for it like:
for (int i = 0; i < 5; j++) {
// Search and load text in the ListView..
}
But sometimes the webpage has 5 "textfields" but maybe a new post got 8..
So, I don't want to use the 5 in the for loop anymore.. I want a for loop which is loading and loading untill he find a specific line in the html code of the webpage.
For example:
if (MaxLoad != "<p>End of the textfields</p>") {
// Search and load text in the ListView,
// untill the found text is the text between the "".
}
}
else{
Log.e("Max textfields are found!")
}
Sometimes he need to stop after 3 textfields.. But another time he need to stop after 16 textfields..
I hope I was clear enough.
Thanks,
P.S. All my code is working at the moment.. When I use the for loop system, count the textfields in the HTML manually.. Put that value into the for loop, then the code load all the textfields.. But I want it automaticly..

Use the break; statement to break out of your for loop. You can initiate the for loop with a big number like 5000.
for (int i = 0; i < 5000; j++) {
// Search and load text in the ListView..
String ItemText = .......
if ( ItemText.equals ( "blablabla" ) )
break;
}
This could be done more elegant though...

Android Jsoup in service - get text of span

Im pretty new to jsoup. For days im trying now to read out a simple number from a span without any success.
I hope to find help here. My html:
<div class="navi">
<div class="tab mail">
<a href="/comm.php/indexNew/" accesskey="8" title="Messages">
<span class="tabCount">1 </span>
<img src="/b2/message.png" alt="Messages" class="moIcon i24" />
</a>
</div>
The class tabCount excists 3 times though in the whole document and I am interested in the first span with this class.
Now I am trying in onCreate() of a service to create a thread with:
Thread downloadThread = new Thread() {
public void run() {
Document doc;
try {
doc = Jsoup.connect("https://www.bla.com").get();
String count = doc.select("div.navi").select("div.tab.mail").select("a[href]").first().select("tabCount").text();
Log.d("SOMETHING", "test"+(count));
} catch (IOException e) {
e.printStackTrace();
}
}
};
downloadThread.start();
This forces my app to crash. The same if i change text() to ownText(). if i remove text() then the app can start but it gives me null.
what am i doing wrong? By the way, besides the service a webview is loading the same url. might that be a problem?

You only need to select the element you're interested in, you don't need to get every outer element before. In your example you could try
String count = doc.select("span.tabCount").text();
Where you define the type of the element "span" and class name ".tabcount"
For an example that might help you, look at this link
Edit:
Try this code instead, this will get the value of the first span.
Elements elements = doc.select("span.tabCount");
String count = elements.first().text();
And if you want to print all elements you could do like this.
Elements elements = doc.select("span.tabCount");
for (Element e : elements) {
Log.d("Something", e.text();
}

Haven't you meant .select(".tabCount")?
BTW, on Android AsyncTasks are more convenient than Threads. Also, empty catch blocks are a bad practice.

Your select statement is wrong. You can insert the whole selection string in one line. Furthermore you have to prefix "tabCount" with a dot as it is a class.
String count = doc.select("div.navi div.tab.mail a").first().select(".tabCount").text();

Parsing problem in android

I have create an android application where parse data using saxparser .But Problem is that it does not parse the whole string inside the tag. The first 4 or 5 word is shown. Why i do not able to parse the whole string inside the tag. I follow the site....
http://www.androidpeople.com/android-xml-parsing-tutorial-using-saxparser
Please help me . Thank in advance.

Use this in the character method of your xml handler
public void characters (char ch[], int start, int length) {
if (buf!=null) {
for (int i=start; i<start+length; i++) {
buf.append(ch[i]);
}
}
}
Where buf is a string builder.

The tutorial you followed has a bug in their characters method. The characters method may be called multiple times per tag, so you need to append the characters to your current value rather than starting a new String.
