How to call setText() using a Float data type?

Question

    public void onClick(View v) {
    switch(v.getId()){
    case R.id.save2:
        s = text.getText().toString();
        number = Float.parseFloat(num.getText().         


        

Answer 1

If you pass a numeric value as the text to a text field, Android will try to interpret it as a resource Id. Make it a text first. The preferred way is to do:

num.setText(String.valueOf(returnnum));
