Android java compare xml string with edittext

I want to compare a xml string with a string from an edittext oder button.
first I set the text of the button:
button1.setText(getString(R.string.okey));
and now I want to check if the text from the button is the same as R.string.okey from the xml file. Like this I can leave out a new variable.
Is it possible to check if the strings are the same with something like this?
if (button1.getText().toString().equals(getString(R.string.okey))){
}
But that doesn't work for me.
Thank you in advance.

this must work, its just to simple. you must change somehow text on button or maybe getString returns different text (Locale changed?). use logging or debugger to check what is button1.getText().toString() and getString(R.string.okey) at the moment of comparison (equals call)
boolean areEqual = button1.getText().toString().equals(getString(R.string.okey));
Log.i("justChecking", "getString:" + getString(R.string.okey) +
", button1.getText:" + button1.getText().toString() +
", are equal:" + areEqual);
if (areEqual){
}
How to Write and View Logs with Logcat

Store them in variables
String a = button1.getText()+"";
String b = getString(R.string.str)+"";
if(a.equals(b)){ }

String with \n in single string android

I have multiple value in single string, but I want to send in every string value on new line. I have written the following code, but it's not working.
String text ="Address" + strpropertyAddress +"\n"+ "Price" + strPrice;
This is my service method where i pass the string.
sendPropertyApi(text, sendto);
I have checked every where, and it is exactly same. Basically the string data should be sent in on a new line, but it's sent in on a single line.

Assuming(Because of Android tag) you are setting this text in textView or editText, for that I think you have to escape \. So use \\n instead. Try following:
String text ="Address" + strpropertyAddress +"\\n"+ "Price" + strPrice;
Or it is always better to use default line separator like following:
String text ="Address" + strpropertyAddress +System.getProperty("line.separator")+ "Price" + strPrice;

I Build a Brain Trainer app but Not Showing my TEXTVIEW when i run my app and warning is showing do not concatenate text display with setText

sumTextView.setText(Integer.toString(a) + " + " + Integer.toString(b));
This Line show warning you see in pic..

Use String.format();
sumTextView.setText(String.format("%1$d + %2$d", a, b));
With this you can format a string correctly with multiple variables, no matter whether they are strings or integers. This example takes the value of variable a and replaces the placeholder %1$d with it. Same goes for the other variable.

take an string copy whole line in it, then show string in setText
String str = (Integer.toString(a) + " + " + Integer.toString(a));
sumTextView.setText(str);

1. The First String Says that do not concate string with setText property.
String txt = String.valueOf(a) + " + " + String.valueOf(b);
sumTextView.setText(str);
2. Second warning says that your program have possibility to crash or genearte an exception in case if value of a or b is null or not an integer.
So check condition if(a!=null and b!=null) then display text in if condition.

Update "Log.i" in TextView with ScrollBar

I have in my layout.xml a TextView with "id = txtLog".
Where do the test results from my application using:
Log.i("Result:", "Value of x = " + x);
for show result in LogCat.
It is possible to show these results "Log.i" within the TextView?
Note: I left a space at the bottom of my application to show the TextView.
Like a console.
I would like to display these messages on TextView.
If possible create a scroll bar and display every time I use Log.i
I am a beginner, do not know if it is possible. Yet thanks.

I would think
myTextView.setText(myTextView.getText() + "Value of x = " + x + "\n");
would work.
EDIT:
Also, to make the TextView scrollable, you need to set a movement method like so:
myTextView.setMovementMethod(new ScrollingMovementMethod());
EDIT 2:
If you want the information to go to both Log.i and a TextView, then you need a method that holds a reference to the TextView you want to update.
public static void LogToView(TextView myTextView, String title, String message) {
Log.i(title, message);
myTextView.setText(myTextView.getText() + title + ": Value of x = " + x + "\n");
}
Put that in whatever class or in your Activity class. Use it instead of Log.i and the message will be passed to both.

Removing newline from string

Here's my issue:
I have a database and it is full of episodes of a tv show. One column denotes the episode number. I want to display the episodes in a list like this:
Episode 1
Episode 2
Episode 3
etc.
I'm using my own adapter class that extends SimpleCursorAdapter to do this...
Since I had formatting errors I am using Android.R.layout.simple_list_item_1 and Android.R.id.text1
Basically the only reason I have a custom adapter is so I can do something like this:
textView.setText("Episode " + cursor.getString("column_for_episode_number");
The problem is, I get a list that looks like this:
Episode
1
Episode
2
Episode
3
When I try something like this(which worked in a different portion of my code):
String text = "Episode " + cursor.getString("blah");
text = text.replaceAll("\\n","");
I get the exact same list output :(
Why don't I use create a custom view with two textboxes next to each other? It is hard for me to get that to look pretty :/

text.replaceAll(System.getProperty("line.separator"), "");

There is a mistake in your code. Use "\n" instead of "\\n"
String myString = "a string\n with new line"
myString = myString.replaceAll("\n","");
Log.d("myString",myString);

Check if there is new line at the beginning before you replace and do the same test again:
for(int i=0; cursor.getString("blah").length()-1; i++)
{
if(cursor.getString("blah").charAt(i)=='\\n') <-- use the constant for the line separator
{
Log.i("NEW LINE?", "YES, WE HAVE");
}
}
Or use the .contains("\n"); method:
Check the xml for the width of the textview as well.
Why are you using getString() when you are fetching an integer? Use getInt() and then use Integer.toString(theint) when you are setting the values in a textview.

This could help you:
response = response.replaceAll("\\s+","");

It sounds like you are hitting wrapping issues rather than newline issues. Change this:
String text = "Episode " + cursor.getString("blah");
To this:
String text = "Episode" + cursor.getString("blah");
And see if that changes the output. Post your layout xml please?

this worked for my (on android 4.4):
(where body is a string with a newline entered from an EditText view on handset)
for (int i=0; i<body.length(); i++) {
if (body.charAt(i) == '\n' || body.charAt(i) == '\t') {
body = body.substring(0, i) + " " + body.substring(i+1, body.length());
}
}

have you tried
cursor.getString("blah").trim()
