How can i read the input from the keyboard?

[Wuque]

Hi you all! I'd like to know how to read the inputs from the keyboard on Android. In java i use:


InputStreamReader reader = new InputStreamReader (System.in);
BufferedReader myInput = new BufferedReader (reader);
String str= new String();
str = myInput.readLine();


... but how in Android?

Thanks

Have you looked at this packages:

java.io Provides input and output facilities by means of streaming, filesystem access and serialization.
java.lang Provides core classes of the Android environment.

Go to http://code.google.com/android/reference/packages.html for all android API's

The best way I've seen to this point is to use an EditText object which has a call to getText() that you can make to get what is currently in the corresponding text box.

I generally create the EditText view in the xml file. Be sure to give it an id by using:

android:id="@+id/your_id_here"

Then in the java...above onCreate() you should initialize the object so that you can access it throughout the file. Then within on create you'll want to do the following:

editTextView = (EditText) findViewById(R.id.your_id_here);

Then you should be able at any time to call editTextView.getText()

I am having a problem with a simple pay check calculator.

I have an EditText for hours worked, and one for hourly wages. However, I'm lost when it comes to snagging the input from those EditTexts. I have tried the editText.getText() method, but when I add that to say total = editText.getText() I get an error saying type conversion of Editable to double is not allowed.

Sorry if this is the wrong place to post this. I have tried several searches and this one seemed to be the best place from what the search yielded.

Thanks in andvance

Just thought I would post this in case someone reads through this and is having a similar problem.

I have corrected the problem, although I have ran into a new one, but it was fixed by:

1st of all, the data types I'm working with are float

2nd I changed the declaration of my variables to be:

Float.parseFloat(editText.getText().toString());

And the new problem is?

Wow, didn't think anyone was using this Forum anymore. Thanks for posting.

Anywhere that I have changed the variable declaration of say:

float myFloat = Float.parseFloat(editText.getText().toString());

Causes the app to crash. I can't figure out how to get by this. I have changed the parseFloat() to valueOf() and it still does the same thing. I dunno if I'm using the right things to solve the problem. I only want to perform a simple calculation based upon input from the user.

I am active, not the forum :b

I guess you get an inputformatexception or something in that direction?

If yes, what's in that txtBox.?

Well to be honest I haven't really sat down and tried using the Debugger that comes with Eclipse. All I get is an un-expected error, but to answer your question when I test the application I use float integers 8.0, 7.0, etc.

To be brutaly honest, I have no clue on how to view any of the error messages that may be thrown out. I just get the dreaded box at application startup saying that there was an unexpected error and the application has quit. Then ensues the force close and wondering where I went wrong.
