Getting Decimal Number From Edittext

I know something similar has already been asked, but I'm having some trouble to get a decimal number that come from keyboard. My Java code in the onCreate method should be: textS0

Solution 1:

Just do this:

double S0 = Double.parseDouble(textS0.getText().toString());

Solution 2:

textS0=(EditText)findViewById(R.id.editS0);
Button btn_S0=(Button)findViewById(R.id.getS0);

btn_S0.setOnClickListener(new View.OnClickListener() 
{
publicvoidonClick(View v)
{

           double S0 = Double.parseDouble(textS0.getText().toString());
}
});

Solution 3:

May b you face null pointer exception in string so try this....

1. get the number decimal from edittext using this

   Double BText=ParseDouble(String.valueOf(edittext.getText()));
   

2. after that paste this code.. it prevents you from null pointer exception

   double ParseDouble(String strNumber) {
   if (strNumber != null && strNumber.length() > 0) {
       try {
           returnDouble.parseDouble(strNumber);
       } catch(Exception e) {
           return -1;
       }
   }
   elsereturn0;
   }
