I'm working on my code to check the types of the place base on place details following this document (https://developers.google.com/android/reference/com/google/android/gms/location/places/Place).
I manage the value from List, the question is how I can display the string for example place a is restaurant, place be is bank from the class. Or should I create an array based on the document? Please advise.
final Place place = PlacePicker.getPlace(this, data);
final List<Integer> types = place.getPlaceTypes();
Toast.makeText(getApplicationContext(), types.get(0).toString(), Toast.LENGTH_SHORT).show();
Regards, -sea-
You could do something as crazy as:
int myPlaceType = 1;
Field[] fields = Place.class.getDeclaredFields();
for (Field field : fields) {
Class<?> type = field.getType();
if(type == int.class) {
try {
if(myPlaceType == field.getInt(null)) {
Log.i("Testing", "onCreate: " + field.getName());
break;
}
} catch (IllegalAccessException e) {
e.printStackTrace();
}
}
}
This will print TYPE_ACCOUNTING to your Android console.
Where myPlaceType is the int place type...
Not perfect, and I hope someone has a better suggestion!

Is it possible to show the keys of my strings in strings.xml instead of the value, would be cool to check which key is it directly in the UI.
for example
<string name="jobs_key">Jobs</string>
i would like to show in the UI jobs_key instead of Jobs
use Resources.getResourcesName(int),
Return the full name for a given resource identifier
here you can find the documentation. You can also use reflection:
private ArrayList<String> getKeysName(Context context, String className) {
Class c;
ArrayList<String> fieldsName = new ArrayList<String>();
try {
c = Class.forName(context.getPackageName() + ".R$" + className);
Field[] fields = c.getDeclaredFields();
for (Field f : fields) {
Log.e("LOG_TAG", " " + f.getName());
fieldsName.add(f.getName());
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
return fieldsName;
}
and call it like getKeysName(context, "string");, to get, for instance all the keys declared inside string.xml.
i have a problem with format arrayList.I have one parameter it have value
Licence_car:[[คย1453 กรุงเทพมหานคร], [รง2344 กรุงเทพมหานคร], [รน4679 กรุงเทพมหานคร]] (Data is a ThaiLanguage)
I use this parameter to set entry of list preference but it will show like this
I want to delete character is "[" and "]" to make a variable like this Licence_car:[คย1453 กรุงเทพมหานคร, รง2344 กรุงเทพมหานคร, รน4679 กรุงเทพมหานคร] how can i do that?
This is my code set entry to list preference.
#SuppressWarnings("unchecked")
public void showCar(Context context,ArrayList<String> currentCars){
SharedPreferences MYprefs = context.getSharedPreferences(PREFERENCES, PREFERENCE_MODE);
if (null == currentCars) {
currentCars = new ArrayList<String>();
}
try {
currentCars = (ArrayList<String>) ObjectSerializer.deserialize(MYprefs.getString("car_licence_", ObjectSerializer.serialize(new ArrayList<String>())));
//String[] car_list = currentCars.toCharArray;
Log.d(TAG,"Licence_car:"+currentCars);
final CharSequence[] charSequenceCarEntry = currentCars.toArray(new CharSequence[currentCars.size()]);
mCarDefault.setEntries(charSequenceCarEntry);
mCarDefault.setEntryValues(charSequenceCarEntry);
mCarDelete.setEntries(charSequenceCarEntry);
mCarDelete.setEntryValues(charSequenceCarEntry);
} catch (IOException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
I get a preference value in arrayList and format to CharSequence[] for set entry to list preference i think that i do format from this point but i don't know how can do it.
Thank for any answer and sorry for my English.
Hello Developer,
You can foramt your charsequence before storing into array list ,hete i am giving the sample code please use it so here it is-
CharSequence[] charSequenceCarEntry = new CharSequence[10];
int startindex=charSequenceCarEntry.toString().indexOf("[");
int endindex=charSequenceCarEntry.toString().indexOf("]");
CharSequence cs =charSequenceCarEntry.toString().substring(startindex, endindex);
so in your case use it like-
currentCars = (ArrayList<String>) ObjectSerializer.deserialize(MYprefs.getString("car_licence_", ObjectSerializer.serialize(new ArrayList<String>())));
final CharSequence[] charSequenceCarEntry = currentCars.toArray(new CharSequence[currentCars.size()]);
int startindex=charSequenceCarEntry.toString().indexOf("[");
int endindex=charSequenceCarEntry.toString().indexOf("]");
CharSequence cs =charSequenceCarEntry.toString().substring(startindex, endindex);
mCarDefault.setEntries(cs);
mCarDefault.setEntryValues(cs);
mCarDelete.setEntries(cs);
mCarDelete.setEntryValues(cs);
I have solve this problem. I create input variable is type list<string> car_entry; to input a car_licence and output result is [คย1453 กรุงเทพมหานคร] so i will try to change type variable to String and the output is คย1453 กรุงเทพมหานคร as a result of charSequenceCarEntry is Licence_car:[คย1453 กรุงเทพมหานคร, รง2344 กรุงเทพมหานคร, รน4679 กรุงเทพมหานคร].Ok now It is done thank for any answer again. :)
I need to retrieve some text from a RemoteViews object. It is possible for me to get the LayoutId, but I have no idea how to retrieve text from a TextView that is in this RemoteView (namely a notification).
Also the RemoteView only contains setters, but no getters, so I guess I have to use the LayoutId (somehow).
Can you help me with that? Thanks!
/edit: The reason why I am asking this, is because I have an AccessibilityService that retrieves the notification. Therefore this is the only way of retrieving the value.
/edit2: I use this code for receiving the notification:
#Override
public void onAccessibilityEvent(AccessibilityEvent event) {
if (event.getEventType() == AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED) {
List<CharSequence> notificationList = event.getText();
for (int i = 0; i < notificationList.size(); i++) {
Toast.makeText(this.getApplicationContext(), notificationList.get(i), 1).show();
}
if (!(parcel instanceof Notification)) {
return;
}
final Notification notification = (Notification) parcel;
doMoreStuff();
}
}
With the notification object I have access to a RemoteViews (notification.contentView) and to a PendingIntent (notification.contentIntent).
To get the layoutId, I can call contentView.getLayoutId()
I proposed a similar solution here that also uses reflection to solve the problem, but in a more approachable fashion. This is my solution. In this context, the RemoteViews came from a Notification, so the first three lines can probably be ignored if you already have access to the RemoteViews object. The link on the page provides a much more detailed explanation of what is actually going on. I hope this will help anyone with a similar problem.
public static List<String> getText(Notification notification)
{
// We have to extract the information from the view
RemoteViews views = notification.bigContentView;
if (views == null) views = notification.contentView;
if (views == null) return null;
// Use reflection to examine the m_actions member of the given RemoteViews object.
// It's not pretty, but it works.
List<String> text = new ArrayList<String>();
try
{
Field field = views.getClass().getDeclaredField("mActions");
field.setAccessible(true);
#SuppressWarnings("unchecked")
ArrayList<Parcelable> actions = (ArrayList<Parcelable>) field.get(views);
// Find the setText() and setTime() reflection actions
for (Parcelable p : actions)
{
Parcel parcel = Parcel.obtain();
p.writeToParcel(parcel, 0);
parcel.setDataPosition(0);
// The tag tells which type of action it is (2 is ReflectionAction, from the source)
int tag = parcel.readInt();
if (tag != 2) continue;
// View ID
parcel.readInt();
String methodName = parcel.readString();
if (methodName == null) continue;
// Save strings
else if (methodName.equals("setText"))
{
// Parameter type (10 = Character Sequence)
parcel.readInt();
// Store the actual string
String t = TextUtils.CHAR_SEQUENCE_CREATOR.createFromParcel(parcel).toString().trim();
text.add(t);
}
// Save times. Comment this section out if the notification time isn't important
else if (methodName.equals("setTime"))
{
// Parameter type (5 = Long)
parcel.readInt();
String t = new SimpleDateFormat("h:mm a").format(new Date(parcel.readLong()));
text.add(t);
}
parcel.recycle();
}
}
// It's not usually good style to do this, but then again, neither is the use of reflection...
catch (Exception e)
{
Log.e("NotificationClassifier", e.toString());
}
return text;
}

CommonsWare in this question says:
... App widgets are write-only: you can push data to them, but you
cannot read them. Instead, when you update your app widget with
new text, you will need to store that text somewhere, perhaps in a
file.
His answer seems to be logical.
If you are targeting on Android 19+, you can use the following code for getting title/text from a Notification object without using any private APIs.
Notification noty = ...;
Bundle extras = noty.extras;
if (extras != null) {
String title = extras.getString(Notification.EXTRA_TITLE);
String text = extras.getString(Notification.EXTRA_TEXT);
}
I am getting the most bizzarre behavior with trying to parse an XML, I run through it step by step and all values are assigned and retrieved in order and then the object I create is added to a HashMap for easy look up, the problem is when I am done retrieving it all the HashMap has null values and the ones that aren't null are the value of the very last node that was read, I have walked through it over and over and it all seems correct, but when it's done loading the values in the HasMap look like:
[0] null
[1] NarrationItem#44e9d170
[2] null
[3] null
[4] NarrationItem#44e9d170
etc, etc.
The format of my XML files is:
<narrations>
<narration id="0" name="A" alias="a" >
<line text="This is a test."></line>
</narration>
<narration id="1" name="B" alias="b" >
<line text="This another a test."></line>
</narration>
<narration id="2" name="C" alias="c" >
<line text="This is STILL a test."></line>
</narration>
</narrations>
And my XML parsing method is follows:
public HashMap<String, NarrationItem> NarrationMap = new HashMap<String, NarrationItem>();
private void LoadNarrationsXML() {
NarrationItem i = new NarrationItem();
String line;
String s;
try {
// Get the Android-specific compiled XML parser.
XmlResourceParser xmlParser = this.getResources().getXml(R.xml.narrations);
while (xmlParser.getEventType() != XmlResourceParser.END_DOCUMENT) {
if (xmlParser.getEventType() == XmlResourceParser.START_TAG) {
s = xmlParser.getName();
if (s.equals("narration")) {
i.Clear();
i.ID = xmlParser.getAttributeIntValue(null, "id", 0);
i.Name = xmlParser.getAttributeValue(null, "name");
i.Alias = xmlParser.getAttributeValue(null, "alias");
} else if (s.equals("line")) {
line = xmlParser.getAttributeValue(null, "text");
i.Narration.add(line);
}
} else if (xmlParser.getEventType() == XmlResourceParser.END_TAG) {
s = xmlParser.getName();
if (s.equals("narration")) {
NarrationMap.put(i.Alias, i);
}
}
xmlParser.next();
}
xmlParser.close();
} catch (XmlPullParserException xppe) {
Log.e(TAG, "Failure of .getEventType or .next, probably bad file format");
xppe.toString();
} catch (IOException ioe) {
Log.e(TAG, "Unable to read resource file");
ioe.printStackTrace();
}
}
The NarrationItem object is a custom object defined as:
public class NarrationItem {
int ID;
String Name;
String Alias;
ArrayList<String> Narration = new ArrayList<String>();
public NarrationItem() { }
public void LoadNarration(int id, String name, String alias, ArrayList<String> narration) {
ID = id;
Name = name;
Alias = alias;
Narration.addAll(narration);// = narration;
}
public void Clear() {
ID = 0;
Name = "";
Alias = "";
Narration.clear();
}
}//End Narration
If someone could point out the problem I'd be very thankful I have sat here staring at this issue for hours.
You're only ever creating one NarrationItem object - you're then using a reference to that object as the value for multiple entries in the map. Don't do that. You need to understand that the map doesn't contain an object as the value - it contains a reference to an object.
You can probably fix this just by creating a new NarrationItem each time instead of calling Clear.
It's not clear how you're looking at the map to see those null values, but if you're using the debugger and looking at the internal data structure, you probably shouldn't really be doing that either - instead, step through the keys, values or entries, i.e. stick within the abstraction that HashMap is meant to support.
I am a new developer on android application. I would like to get the ISO Country code when I pass the mobile number with country code. If I pass the mobile number as 1-319-491-6338, can I get country ISO code as US / USA in android?
I have written the code as follows:
TelephonyManager tm = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
String countryCode = tm.getSimCountryIso();
String mobileno="1-319-491-6338";
Here, where can I pass the mobile number?
Can anybody please help me ?
Thanks in advance
You may not be able to query the country code programmatically via the standard API but you could include a table in your app. Such a table is easily found via Google (e.g. http://countrycode.org/).
Danger Will Robinson!: However, one should ask yourself what question you are trying to answer. Implicit in your question is that assumption that there is a one-to-one mapping between international dialling codes and ISO country codes. This is not true. For example, both the USA and Canada have the international dialling code '1'.
Perhaps think about re-structuring your app's interface. Allow the user to select a country to associate with the phone number but use the table from http://countrycode.org/ to order the most likely candidates at the top?
Had the same problem. Eventually I put all the data in excel and read the excel sheet.
Here is the implementation:
copy-past the country code table from http://countrycode.org/ to Microsoft Excel file.
Save the Excel file as 97-2003 compatible (.xls) in \res\raw\countrycode_org.xls
Download JExcelApi from here
Use the following class to read the file:
public class CountryCodes {
private HashMap mCountryByName = new HashMap();
private HashMap mCountryByCode = new HashMap();;
private ArrayList mCountries = new ArrayList();
public void addCountry(String countryName,String ISO_code,String countryCode){
countryCode = PhoneNumberUtil.normalizeDigitsOnly(countryCode);
Country country = new Country();
country.Name = countryName;
country.Code = countryCode;
country.ISO_code = ISO_code;
mCountryByName.put(countryName, country);
mCountryByCode.put(countryCode, country);
mCountries.add(country);
return;
}
public Country getCountryByCode(String countryCode){
countryCode = PhoneNumberUtil.normalizeDigitsOnly(countryCode);
return mCountryByCode.get(countryCode);
}
public Country getCountryByName(String countryName){
return mCountryByName.get(countryName);
}
public Country getCountryByIsoCode(String ISO_code){
ISO_code = ISO_code.toUpperCase();
for (Country country:mCountries){
String [] strArr = country.ISO_code.split("/| ");
for (String s:strArr){
if (ISO_code.equals(s))
return country;
}
}
return null;
}
public String[] getCountryNamesList(){
String[] res = new String [mCountries.size()];
int i=0;
for (Country c:mCountries){
res[i] = c.Name;
i++;
}
return res;
}

Step-1
You can get country calling code as well as its ISO name in the following URL
http://en.wikipedia.org/wiki/List_of_country_calling_codes
or
http://www.unc.edu/~rowlett/units/codes/country.htm
Step-2 You can get page source of that file using java program. You will get file in HTMl format
Step-3 you can convert those HTML files into XML format using any of available parsers. see Open Source HTML Parsers in Java
Step-4 Form the phone number you can get the calling code. Example if the number is "1-319-491-6338" then calling code is 1
Step-5 Match this calling code against the calling code and country name list that you have got from XML parser. In this way you can get iso country
