NumberFormatException Error

Question

the code is:

editText2=(EditText) findViewById(R.id.editText2);
editText3=(EditText) findViewById(R.id.editText3);
float from_value= Float.parseFloat(editTe         


        

Answer 1

to me the best way is to do it like this:

editText2=(EditText) findViewById(R.id.editText2);
editText3=(EditText) findViewById(R.id.editText3);

if(!editText2.getText().toString().matches("")){
float from_value= Float.parseFloat(editText2.getText().toString());
editText3.setText(" "+(from_value * 100.0));
}

And also add this line to your xml for editText2

android:inputType="numberDecimal"

Hope it helps !
