i'm using autocompletebubbletext library (https://github.com/FrederickRider/AutoCompleteBubbleText) which display the list of items to chose from in a list and allow in same time to chose the items from the editetxt..
My problem is as follow:
after the user choses a number of items(=Multiple inputs) .. i want to display a text as an output when clicked on a button (depending on the items chosen of course) as explained in this picture: (https://i.imgur.com/QQuzFvl.png)..
but i got stucked in getting the string of itemsChosen from the edittext
FIRST: i am not sure which return value to use!!
SECOND: i assumed i should use "checkedIds" and I've tried A lot of solution in internet , i've been trying different ideas all day, from what i have tried: ( Ps: i used a toast to see if the methods did work)
edittext.getText().toString() > nothing appears in Toast
i have tried to turn the setHash to String[]: then turning the String[] to one string like:
content=editText.getCheckeditems();//getcheckeditems returns checkedIds which is = new HashSet<String>()
String[] BLANA= content.toArray(new String[content.size()])
data= TextUtils.join(",",BLANA);
it didnt work, in Toast i got"[]"
For the MainActivity.Java (i have the same as here):
https://github.com/FrederickRider/AutoCompleteBubbleText/blob/master/samplelist/src/main/java/com/mycardboarddreams/autocompletebubbletext/samplelist/SampleActivity.java
For MultiSelectEditText.java (i Have same as here) :
https://github.com/FrederickRider/AutoCompleteBubbleText/blob/master/library/src/main/java/com/mycardboarddreams/autocompletebubbletext/MultiSelectEditText.java
WHAT is the solution? (to get a string so i can use it later)
PS: if there is another way(another library or methode) to get what i want to achieve in the first place , i would love to try it..
EDIT: THIS IS A CODE THAT LOOKS PROMISING BUT DIDN'T WORK!
in MultiSelectEditText.java
public String datachosen(){
String [] blan= checkedIds.toArray(new String[0]);
StringBuilder builder = new StringBuilder();
for (String string : blan) {
if (builder.length() > 0) {
builder.append(" ");
}
builder.append(string);
}
String DATATORETURN = builder.toString();
return DATATORETURN;
}
in MAINACTIVTY.JAVA
MultiSelectEditText editText = (MultiSelectEditText)findViewById(R.id.auto_text_complete);
content=editText.datachosen();
Toast.makeText(DecisionTree.this, content,
Toast.LENGTH_LONG).show(); // TOAST INCLUDED IN A BUTTON OF COURSE
OUTPUT: TOAST SHOWS NOTHING!
Solved it ..
i intialize the edit text before on create ..and defin it later after onCreate()..
and got string with the normal edittext.getText().toString(); method!
Simple but was hard to detect the problem!

I need to create a program to store all words in an array list. Then check the user input from the textfield to see if it starts with anything other than numbers and punctuation. Otherwise it will need to display an error and prvent the string to be added to the arraylist and display an appropriate error.
https://pastebin.com/8UwDm4nE
Heres the ActionEvent listener that contins the code to check that. Im not really sure how to get it working.
#Override
public void actionPerformed(ActionEvent e) {
for(int i = 0; i < 1; i++) {
String str = tf.getText(); // MUST BE STORED ON AN ARRAY LIST
ta.append(str + "\n"); // Append the text on new line each
if(str.startsWith(String.valueOf(nums))) { // Check input for a number at the start
error.setText("Error: Word starts a number. Please try again!");
error.setForeground(Color.RED);
ta.append("");
} else if (str.startsWith(String.valueOf(punct))) { // Check if input contains a punctuation at the start
error.setText("Error: Word starts with an illegal character. Please try again!");
error.setForeground(Color.RED);
ta.append("");
}
}
}
I'm going to rephrase your problem a bit as clarification, please correct me if I'm misunderstanding.
You have a text field and a text area. You want a user to type a word into the text field and submit it. If that word starts with a number or punctuation, then indicate an error to the user. Otherwise, add it to the text area (on a new line) and the inner ArrayList.
To solve this problem, there are a couple things you'll need:
An ArrayList<String> that is a class member variable where you can store your words
An event handler that handles the button click.
The event handler should:
Parse the string from the text field (using getText(), as you already are).
Do the error checks you're already doing.
If neither of the error conditions are hit (so add an else clause for this), add the word to the text area (which you're already doing) and add it to the ArrayList.
Hopefully this helps you get a clearer idea of how to approach the problem. If not, please post a code sample of what you tried and what error you're specifically running into.
EDIT:
Here is some pseudocode for your if-else error-handling block of code, assuming you declare a new ArrayList to hold your words as a class member:
// as class member variable
List<String> wordList = new ArrayList<>();
// word handler code
if (str starts with a number) {
// handle error
} else if (str starts with punctuation) {
// handle error
} else {
ta.append(str + "\n");
wordList.add(str);
}
I am pulling data from a Website to my application. I want the TextView to display the result I want from the website immediately as the user launches the app. However html codes make the result look weird some times and I am trying to correct it. I have the codes that will do what I am trying to do. I just can't figure out how to get it to do everything automatically at app launch. It needs to pull the code from the website and if it receives any special symbols within the string I want it to correct it as soon as the app launches. Here is an example...
TextView tv = (TextView) findViewbyId(R.id.my_textview_result);
tv.setText(resultFromWebsite);
The result it pulled: You u0026 Me Forever!
The result I want: You & Me Forever! My app should correct that.
Here is my correction code...
public void symbolTextFilter(TextView myTv) {
String getData = tv.getText().toString();
if (getData.contains("u0026") {
String replace = getData.replace("u0026", "&");
myTv.setText(replace);
}
Now on my onCreate Method
TextView tv = (TextView) findViewbyId(R.id.my_textview_result);
tv.setText(resultFromWebsite);
symbolTextFilter(tv);
It will not make that correction. It will if I put the symbolTextFilter(tv) in a onClickListener button though. I don't want to assign the correction in a button. I want it automatically. My guess is, everything that I have in the onCreate is happening too fast for corrections to be made. How do I fix that? Thanks in advance!
Try this:
tv.setText(symbolTextFilter(resultFromWebsite))
You should use the method symbolTextFilter to handle the string only:
public void symbolTextFilter(String input) {
if (input.contains("u0026") {
return input.replace("u0026", "&");
} else {
return input
}
Nevermind, I got it! I'm not sure where the "\" came from because it wasn't in the original string that it pulled before the correction. I fixed it with this...
public String symbolTextFilter(String input) {
if (input.contains("u0026") {
return input.replace("\\" + "u0026", "&");
} else {
return input
}
I want to show sentences for its number.
Getting number with EditText, and sentences are in string.xml
Name of strings are
sen_(number)
ex: sen_1, sen_25
I tried to make the code to String, so I did like this.
(sentence_num is getString of EditText) (sen_1 is "Hello, world!")
String getTxtString = "getText(R.string.sen_" + sentence_num + ")";
TextView scrambled_sen = (TextView)findViewById(R.id.scrambled_sentence);
scrambled_sen.setText(getTxtString);
But it shows getText(R.string.sen_1), not "Hello, world!".
How can I make it show string with its number?
I want to put getTxtString for a java code, not a String.
You could use getResources().getIdentifier() to get the string but a better and non-complicated way is through a switch case or the if else method.
Something like
If(editText value equals something){
return getString(R.string.sen_1);
}
Minimizes the errors that you could cause through the first getIdentifier() method too.
This is a problem I've been trying to fix for 3 hours now.
How the app works:
I've got a list of numbers in a txt file (in assets). I'm reading that txt file line by line and I set the text of a TextView to the current line. Now I have to type the same number in an EditText. But if I compare the EditText and the current line, the app says they are not the same, although they are.
I've got a file in assets with different numbers, like this:
3
9
8
14
[finish]
The [finish] tag will be used later so I can finish the application, but is pretty unnecessary now.
I've defined the following strings and views:
public String curval;
public EditText etds;
public TextView curvalte;
A part of my onCreate() method:
etds = (EditText)findViewById(R.id.editText1);
buttonds = (Button)findViewById(R.id.button1);
curvalte = (TextView)findViewById(R.id.textView2);
try {
inds = this.getAssets().open(assetname);
} catch (IOException e) {
e.printStackTrace();
}
readerds = new BufferedReader(new InputStreamReader(inds));
Now I'm reading from the file and setting it as text of curvalte:
curval = readerds.readLine();
curvalte.setText(curval);
And it works just fine.
But then you have to type the same number that is now shown in curvalte in the EditText.
If I try to use equals() on the text in EditText with curval, it always says that EditText.getText().toString doesn't equal curval:
if(etds.getText().toString().equals(curval.toString()){
// The code here
}else{
// This is what I get
Toast.makeText(getBaseContext(), "Wrong answer!", Toast.LENGTH_LONG).show();
}
Even if I enter the correct answer, I get that toast saying it's wrong.
Removing the .toString() didn't fix it and I've got no idea what I could try.
Maybe it's because of the string that actually contains a number?
Try printing both of the values out and looking at them. You may not even be getting the right values from the file or perhaps your getting some weird formatting characters like "\n"
Try this with .trim(), sometimes that is the issue
if(etds.getText().toString().trim().equals(curval.toString().trim()){
// The code here
}else{
// This is what I get
Toast.makeText(getBaseContext(), "Wrong answer!", Toast.LENGTH_LONG).show();
}
Alright, I found the problem. It was the formatting of the assets file!
Cp1252 encoding fixed it.
Maybe you have spaces in the string or the difference between Uper and LowerCase. Try this version:
if(etds.getText().toString().trim().toLowerCase().equals(curval.toString().trim().toLowerCase())){
Log.i("Yes", "equal");
} else {
Log.i("NO", "not equal");
}
I'm writing an app that takes in an input from the AddBook class, allows it to be displayed in a List, and then allows the user to Search for their book. To this end, I'm creating a temporary EditText, binding it to the box where the user actually enters their search value, then (after ensuring that it is not empty) I compare what they've entered for the ISBN number with the ISBN numbers of each entry in the arrayList of <Book> custom objects, the list being named books.
Problem is, when I try to parse the EditText into an Int, it doesn't seem to work. I first tried using toString() on the EditText, then using Integer.parseInt() on the result of that method, but it hasn't worked out, as the conversion is seemingly unsuccessful;
All of the resources are in place and the code compiles properly, so those aren't the problems here.
EditText myEdTx = (EditText) findViewById(R.id.bookName);
if(myEdTx.getText().equals("")){Toast toast = Toast.makeText(this, "Please enter something for us to work with!", Toast.LENGTH_SHORT);
toast.show();}
else{
//resume here
for(int i=0; i<books.size(); i++)
{
Book tBook = new Book(i, null, null); tBook = books.get(i); String s=myEdTx.toString();
int tInt = Integer.parseInt(s);`
To get the string representation of an EditText's content, use:
String s = myEdTx.getText().toString();
Using toString() directly on the EditText gives you something like:
android.widget.EditText{40d31450 VFED..CL ......I. 0,0-0,0}
...which is clearly not what you want here.
You assume the user inputs a number into the text field, but that is unsafe, as you only get a string text (which theoretically can contain non-numbers as well). When I remember correctly, you can adjust a text field in android where a user only can input numbers, which should suit you more.
NumberFormatException occurs when Integer.parse() is unable to parse a String as integer, so, its better to Handle this exception.
String s = myEdTx.getText().toString();
try {
int tInt = Integer.parseInt(s);
} catch( NumberFormatException ex ) {
//do something if s is not a number, maybe defining a default value.
int tInt = 0;
}
So the current String here you are trying to parse is with white space in the line
and integer class unable to parse that white space. So use following code.
String s=myEdTx.getText().toString();
int tInt = Integer.parseInt(s.trim());
String s = myEdtx.getText().toString().trim();
int iInt = Integer.parseInt(s);
