I set the inputType to numberDecimal which works fine, except that this allows people to enter numbers such as Here is a sample InputFilter which only allows max 4 digits before the decimal point and max 1 digit after that. Values that edittext blocks: This solution will not allow the user to enter more than two digit after decimal point. Also you can enter any number of digits before decimal point.
I hope this will help. Thank you. Add the Listener in your onCreate. Try using NumberFormat. Edit — There is no inputType for currency that I could find in the docs. As LeffelMania mentioned, you can correct user input by using the above code with a TextWatcher that is set on your EditText. The requirement is 2 digits after decimal.
There should be no limit for digits before decimal point. So, solution should be. All answers here are pretty complex I tried to make it much simpler. Look at my code and decide for yourself —.
I have modified the above solutions and created following one. You can set number of digits before and after decimal point. The InputFilter I came up with allows you to configure the number of digits before and after the decimal place. Additionally, it disallows leading zeroes. What this does is when you exit editing phase it formats the field to the right format. At them moment it has only 2 decimal charachters.
I think this is pretty easy way to do this. If the user enters a number with more than two numbers after the decimal point, it will be automatically corrected. I wanted to be able to reuse the code in many EditTexts.
This is my solution:. The problem was that the solution only tested the previous text that had been entered, not the current text being entered. So here is my solution that inserts the new character into the original text for validation. I improved on the solution that uses a regex by Pinhassi so it also handles the edge cases correctly.
Before checking if the input is correct, first the final string is constructed as described by the android docs. Like others said, I added this class in my project and set the filter to the EditText I want. Here one important thing is it does solves my problem of not allowing showing more than two digits after the decimal point in that EditText but the problem is when I getText from that EditTextit returns the whole input I typed.
For example, after applying the filter over the EditTextI tried to set input 1. So in the screen it shows 1. Then I wanted to use this input for some other calculations so I wanted to get the text from that input field EditText. When I called mEditText. This works fine for me.Have you ever needed to display numbers with decimal places whilst coding a program? If so, this is the article for you.
To follow along in Android Studio, go into Project view. In order to implement decimal numbers in Android Studio, we use the keyword Double. To convert prices, we need to have a conversion rate. On a new line above the one in which we declared double variables, declare a constant by using the keyword for constants: final. As well, specify the data type Double. Back with our double variables, set priceCAD to equal 9.
You can do negative numbers, but this example requires positive numbers. The emulator will find an integer when it wants a double variable, which requires decimal places. The string we want to be displayed on the screen goes into the quotation marks of the Toast function. To test our code, run the emulator. This price contains 15 decimals. To format the price to two decimal places, add the following before the string in our Toast function: String.
Enclose the string in the parentheses of that code. As well, inside those parentheses, add the parameter Locale. Put a placeholder for the first decimal that appears after the comma.
Separate the numbers with commas, such as priceUSD, 2. The value of priceUSD will be placed in f. If we have another one called 2. You must be logged in to post a comment. Search for: Search. Products Products. Posted on October 18, by Alexandra Kropova.

Limit Decimal Places in Android EditText
I hope this will help. Thank you. I don't like the other solution and I created my own. You just can't type the digit in excess, no other effects! In additional if you write ". Add the Listener in your onCreate. I have modified the above solutions and created following one. You can set number of digits before and after decimal point. I improved on the solution that uses a regex by Pinhassi so it also handles the edge cases correctly. Before checking if the input is correct, first the final string is constructed as described by the android docs.
I really liked Pinhassi's answer, but noticed that after the user had entered the specified number digits after the decimal point you could no longer enter text to the left side of the decimal point. The problem was that the solution only tested the previous text that had been entered, not the current text being entered. So here is my solution that inserts the new character into the original text for validation.
I've also came across this problem. I wanted to be able to reuse the code in many EditTexts. This is my solution:. The requirement is 2 digits after decimal. There should be no limit for digits before decimal point. So, solution should be. This is to build on pinhassi's answer - the issue that I came across was that you couldn't add values before the decimal once the decimal limit has been reached.
To fix the issue, we need to construct the final string before doing the pattern match. This works fine for me. It allows value to be entered even after focus changed and retrieved back.
For example: I have added your class to my library. Thanks again. I have one question. I am trying to create an additional constructor for DecimalFilter similiar to this I can't seem to figure out how to do that.Mask EditText Library - Android Studio Tutorial
Well that's the thing. I don't see anywhere in your class where it triggers a spot I can call it. From what I can tell, after it reaches the decimal size limit, the class doesn't get called again. Where in the class does the code execute when someone tries typing in after they have reached the limit? Thank you for the updates. That is actually what I thought was supposed to be done as well, but the problem is, that Toast message only executes when you enter the decimal limit and also when you backspace from the limit, NOT when you try to type past the limit.
From what I can tell, once you reach the limit, any other keystrokes except the delete key are ignored. I have set breakpoints on the entire class. When you reach the limit, and try and type, nothing in the class gets invoked, hence why I can't figure out where to put the Toast message so it works properly : The idea I am going for is, that if you are typing and the characters go through, then that is fine.
But if you have reached the limit, and you are typing and nothing is showing up, I want the Toast message to advise you that you have reached the limit and that is why no more characters are being entered. That way the user doesn't think the app is just broken or something. Does that make sense? What about this? This toast also invoked when you reach the limit only. The toast goes off once you have typed the final digit and if you delete the final digit.
I want it to only go off when trying to type past the limit. This way, if the limit is 2 decimal places, and the user is trying to type a third digit, they won't be confused, because they will keep getting a toast saying "You can't go past 2 digits". Right now, it is confusing to the user. See the update Brian Choan. By the way trying to toast from setOnKeyListener we will achieve it.
From here the toast message will appear from you are enter the last digit. Post a Comment.
