I am trying to apply font for my entire application which is having support of multiple indian languages. i am applying the code given below for on or below lollipop.
public void setDefaultAppFont(String fontAssetName)
{
if (Build.VERSION.SDK_INT >= 21)
{
Map newMap = new HashMap();
final String typefaceFieldName = "sans-serif";
newMap.put(typefaceFieldName, Typeface.createFromAsset(appInstance.getAssets(), fontAssetName));
try
{
final Field staticField = Typeface.class.getDeclaredField("sSystemFontMap");
staticField.setAccessible(true);
staticField.set(null, newMap);
}
catch (NoSuchFieldException e)
{
e.printStackTrace();
}
catch (IllegalAccessException e)
{
e.printStackTrace();
}
}
else
{
Typeface typeface = Typeface.createFromAsset(appInstance.getAssets(), fontAssetName);
try
{
Field staticField = Typeface.class.getDeclaredField("DEFAULT");
staticField.setAccessible(true);
staticField.set(null, typeface);
staticField = Typeface.class.getDeclaredField("DEFAULT_BOLD");
staticField.setAccessible(true);
staticField.set(null, typeface);
staticField = Typeface.class.getDeclaredField("SANS_SERIF");
staticField.setAccessible(true);
staticField.set(null, typeface);
staticField = Typeface.class.getDeclaredField("SERIF");
staticField.setAccessible(true);
staticField.set(null, typeface);
staticField = Typeface.class.getDeclaredField("MONOSPACE");
staticField.setAccessible(true);
staticField.set(null, typeface);
}
catch (NoSuchFieldException e)
{
e.printStackTrace();
}
catch (IllegalAccessException e)
{

}
}
Above code allows us to change default english font on or below lollipop devices, but then it is unable to render default english letters coming from strings file and starts converting these english letters into non-english language letters automatically when non-english language is selected by user.
For Example :
I am using a spinner in my application that is having ten language options like, English(Written in english alphabets), Kannada(Written is kannada alphabets), Marathi(Written in marathi alphabets), Gujarati(Written in gujarati alphabets) etc. if user selects a perticular option from that spinner, the whole app language and font changes. It also changes the English(Written in english alphabets) in spinner that should not allowed to be changed in other languages even if user selects any language option.

I tried to manipulate a text to match and extract special or some words in Dart. For example:
I want to check matching of words ends with a given word
String oldText = "website or show me to";
String newText = "show me to tell";
if (oldText.trim().endsWith(newText.trim())) {
final extractText = oldText.trim().substring(newText.length);
print(extractText);
} else {
print("Not matched");
}
I want to extract only word - "tell" so how can I do it? Need to use Regular expression?
Take a look here. I've implemented a regex which will check that tell is followed by end of line $. The regex is probably easier than any other method you might try, plus it's easy to change if conditions change.
void main() {
String oldText = "website or show me to";
String newText = "show me to tell";
RegExp parser = RegExp(r"tell$");
if (parser.hasMatch(oldText)) {
print(parser.stringMatch(oldText).toString());
} else {
print("Not matched");
}
if (parser.hasMatch(newText)) {
print(parser.stringMatch(newText).toString());
} else {
print("Not matched");
}
}
And here is an example where I have removed the check to a function and also set it up so that you can dynamically generate the regex:
void main() {
String oldText = "website or show me to";
String newText = "show me to tell";
String test = "tell";
RegExp parser = RegExp(test+r"$");
print(checkMatch(oldText, parser));
print(checkMatch(newText, parser));
}
checkMatch(text, parser) {
if (parser.hasMatch(text)) {
return(parser.stringMatch(text).toString());
} else {
return("Not matched");
}
}
The attached photo is a representation of my layout.I need to enter the first and last name in the EditTexts. And by pressing the Insert Button, the info is saved to the database. (This part I managed to do) However, on clicking the Show button, the entered input is to be displayed in the TextView which consists of the firstname & lastname. Attached photo
to upload your data into remote database you can use this code
//enregistrement des donnees dans la base de donnees
WebClient client = new WebClient();
Uri uri = new Uri("http://test.com/login.php");
NameValueCollection parameters = new NameValueCollection();
parameters.Add("Email", email);
parameters.Add("Password", password);
client.UploadValuesCompleted += Client_UploadValuesCompleted;
client.UploadValuesAsync(uri, parameters);
it will generate this method
private void Client_UploadValuesCompleted(object sender, UploadValuesCompletedEventArgs e)
{
if (Encoding.UTF8.GetString(e.Result) == "success!!!")
{
Toast.MakeText(this, "success!!!", ToastLength.Long).Show();
}
else if (Encoding.UTF8.GetString(e.Result) == "failed!!!")
{
Toast.MakeText(this, "failed!!!", ToastLength.Long).Show();
}
}
and to retrieve your data you can use code
articles = new JavaList<ModelArticle>();
mWebClient = new WebClient();
mUrl = new Uri(urlAddress);
mWebClient.DownloadDataAsync("your url");
mWebClient.DownloadDataCompleted += MWebClient_DownloadDataCompleted;
it will generate this method
private void MWebClient_DownloadDataCompleted(object sender, DownloadDataCompletedEventArgs e)
{
RunOnUiThread(() =>
{
try
{
string json = Encoding.UTF8.GetString(e.Result);
articles = JsonConvert.DeserializeObject<JavaList<ModelArticle>>(json);
}
catch (Exception exception)
{
Toast.MakeText(this, " Vueillez verifier votre connexion a internet puis reessayer ", ToastLength.Short).Show();
}
});
}
now your result is in the javalist articles don't forget to create a model of your json result
I got Page source using
String pageSource = driver.getPageSource();
Now i need to save this xml file to local in cache. So i need to get element attributes like x and y attribute value rather than every time get using element.getAttribute("x");. But I am not able to parse pageSource xml file to some special character. I cannot remove this character because at if i need element value/text it shows different text if i will remove special character. Appium is use same way to do this.
I was also facing same issue and i got resolution using below code which i have written and it works fine
public static void removeEscapeCharacter(File xmlFile) {
String pattern = "(\\\"([^=])*\\\")";
String contentBuilder = null;
try {
contentBuilder = Files.toString(xmlFile, Charsets.UTF_8);
} catch (IOException e1) {
e1.printStackTrace();
}
if (contentBuilder == null)
return;
Pattern pattern2 = Pattern.compile(pattern);
Matcher matcher = pattern2.matcher(contentBuilder);
StrBuilder sb = new StrBuilder(contentBuilder);
while (matcher.find()) {
String str = matcher.group(1).substring(1, matcher.group(1).length() - 1);
try {
sb = sb.replaceFirst(StrMatcher.stringMatcher(str),
StringEscapeUtils.escapeXml(str));
} catch (Exception e) {
e.printStackTrace();
}
}
try {
Writer output = null;
output = new BufferedWriter(new FileWriter(xmlFile, false));
output.write(sb.toString());
output.close();
} catch (IOException e) {
e.printStackTrace();
}
}
if you will get that kind of problem then catch it with remove special character and parse again.
try {
doc = db.parse(fileContent);
} catch (Exception e) {
removeEscapeCharacter(file);
doc = db.parse(file);
}
It might works for you.
I can able to do same using SAXParser and add handler to do for this.
Refer SAX Parser
I am using the code -
BrowserContentManager browserMngr = new BrowserContentManager(0);
RenderingOptions rendOptions = browserMngr.getRenderingSession().getRenderingOptions();
rendOptions.setProperty(RenderingOptions.CORE_OPTIONS_GUID,RenderingOptions.SHOW_IMAGES_IN_HTML,false);
add(browserMngr);
BrowserContentManagerOAuthDialogWrapper pageWrapper =new BrowserContentManagerOAuthDialogWrapper(browserMngr);
pageWrapper.setConsumerKey("my key");
pageWrapper.setConsumerSecret("my secret");
pageWrapper.setCallbackUrl("https://twitter.com");
try {
pageWrapper.login();
}
catch (Exception e) {
System.out.println("error: "+e.getMessage());
}
This is for Twitter login.The language of the Browser Screen is not in English. So how to change it to English ?.

Note: This Error displaying first "javax.microedition.media.MediaException: There is already another active Player. Call Player.close() on the existing Player to free up the resources." and camera gets open and when i try to take picture this error displays "Error Class Java.lang.ArrayIndexOutOfBoundsException: Index 0>=0"
After _videoControl.getSnapshot( encoding ) has been called you need to close player (i.e. to call player.close(). And that's exactly what the exception tells about.
However this method of taking images is highly unreliable - you'll not be able to use it for every BB device model. I don't know why RIM put it in SDK samples. By doing that RIM pushes developers to a wrong way. As alishaik786 mentiones a proper method of taking images on BB is using Invoke.invokeApplication(Invoke.APP_TYPE_CAMERA, new CameraArguments()) with a FileSystemJournalListener implementation. Just search on StackOverflow on these for the implementation details. I vaguely recall the implementation is painful (like many other parts on BB), but once done it will work on any device.
you got two error
1."javax.microedition.media.MediaException: There is already another active Player. Call Player.close()
this exception thrown if you try to open camera (player) while another instance of camera is already opened. In your code, you need to define the player object as a class level and must close the player after taking the snapshot (also need to close the player if you push from one screen to another).
2."Error Class Java.lang.ArrayIndexOutOfBoundsException: Index 0>=0"
This error may occur when you access encoding array while encoding array size is zero.
You can ensure this issue by using _videoControl.getSnapshot( null), which take the snapshot in default encoding.
So first insure these issue and reply me.
