the code is:
editText2=(EditText) findViewById(R.id.editText2);
editText3=(EditText) findViewById(R.id.editText3);
float from_value= Float.parseFloat(editText2.getText().toString());
editText3.setText(" "+(from_value * 100.0));
And the logcat error is:
03-18 03:19:07.847: E/AndroidRuntime(875): Caused by: java.lang.NumberFormatException: Invalid float: ""
Seems like the String in editText2 is empty, so it fails to parse it as float.
A possible solution is to check if the String is empty first, and then decide about default value, another is to catch the exception:
float from_value;
try {
from_value = Float.parseFloat(editText2.getText().toString());
}
catch(NumberFormatException ex) {
from_value = 0.0; // default ??
}
