Question

I am having an issue with my program, my textveiw will not display any decimals, heres the break down on whats happeneing. The user enters a number in a textEdit (Also how do i make the textedit only accept numbers AND a decimal point?) that number gets converted to a int, sent to my second activity, diveded by 3600, then displayed in a textveiw box. The issue is that when that number is displayed it has no decimal value, for example if its less than 1 it will not display anything, how can i go about fixing this? i need it to at least go to the 1000th place.
Here is my code one activity1:

    public void sendMessage(View view) {
    // Do something in response to button
    Intent intent = new Intent(this, PayTracker.class);
    // Gather text from text boxes
    EditText editText = (EditText) findViewById(R.id.hourly_wage);
    //Create String from text
    String message1 = editText.getText().toString();
    //Convert String to Int
    int HW = 0;
    try{
        HW = Integer.valueOf(message1);
    }
    catch(NumberFormatException nfe){
        //do something else here
        //for e.g. initializing default values to your int variables
    }
    // Send Integers to PayTracker.java
    intent.putExtra(MESSAGE_HW, HW);
    // start new activity
    startActivity(intent);

And then this is activity2 where the number needs to be displayed:

    public void sendMessage(View view) {
    // Receive messages from options page
    Intent intent = getIntent();
    int HW = intent.getIntExtra(Options.MESSAGE_HW, 0);
    // Calculate pay per second
    int PPS = 0;
    PPS = (HW/3600);

    // set textView
    TextView textView = (TextView) this.findViewById(R.id.yourpay);
    textView.setText(String.valueOf(PPS));
}

Any help would be appreciated! thanks!

Answer 1

Use doubles or floats. From what I see, everything should work except that you forgot that 5 divided by 2 as int is 2, and not 2.5.

so do as gtumca said and use doubles; longs are just bigger ints.

in other words…
activity1

try{
    HW = Double.valueOf(message1);
}

activity 2

//double HW = intent.getIntExtra(Options.MESSAGE_HW, 0);
double HW = intent.getDoubleExtra(Options.MESSAGE_HW, 0);
     // pay is rarely a round number
double PPS = HW / 3600;
