Android How To Subtract String From Given String

I'm getting string in button. text I want to display only specific character only but when click show full value in toast how I will do that? Button e01; String[] days = new String

Solution 1:

you can substract from the length.

Stringnumbers= days[1].substring(days[1].length() - 8);

the date is 10 characters, minus 2 it gives last 11

Solution 2:

If you want to show 11 from 2013/09/11 you can do it as -

String[] stringArray = days[1].split("/");
String elevenString = stringArray[stringArray.length-1];

Edit -

e01.setText(elevenString);
eo1.setTag(days[1]);

Now in onclick do this -

@OverridepublicvoidonClick(View v){
    // TODO Auto-generated method stubswitch (v.getId()) {
        case R.id.e01:
            value = (String) e01.getTag();
            Toast.makeText(this, value, Toast.LENGTH_SHORT).show();
            //value=// 2013/09/11break;
    }
}

Solution 3:

Since you are showing a date then year is 4 characters + 2 for month + 2 /,then total of 6 characters you can use subString like below

Toast.makeText(this, value.substring(5), Toast.LENGTH_SHORT).show();

This should work perfectly.

NB:- Never use this way if the string is variable,not like this one.

Solution 4:

String[] SeperatedDateValue= days[1].split("/");//days[1] = "2013/09/11"

/*SeperatedDateValue[0]//Year
SeperatedDateValue[1]//Month
SeperatedDateValue[0]//Day*/


e01.setText(SeperatedDateValue[0]);

And on Button Click

Display your date string as it is on the Toast by using your days[] variable values
