Question

I’m printing an empty string because I want my display to be nothing when the user clicks clear. But for some reason, it’s coming up with zeros instead, any reason why?

display= (EditText) findViewById(R.id.editText1);}

//When button is clicked, display the text. How do I do this for the rest of my variables?

public void onClick(View v)
{
    switch(v.getId())
    {
         case R.id.bOne: display.append("1"); break;
         case R.id.bTwo: display.append("2"); break;
         case R.id.bThree: display.append("3"); break;
         case R.id.bFour: display.append("4"); break;
         case R.id.bFive: display.append("5"); break;
         case R.id.bSix: display.append("6"); break;    
         case R.id.bSeven: display.append("7"); break;
         case R.id.bEight: display.append("8"); break;
         case R.id.bNine: display.append("9"); break;
         case R.id.bZero: display.append("0"); break;
         case R.id.bPoint: display.append("."); break;
         case R.id.bClear: display.setText("");
         case R.id.bAdd: double counter = Double.toString(display);
                        //counter+=counter;
                        //display.setText(counter);

Edit

I’m programming a caclulator in Java for an Android project through Eclipse. And it’s an EditTExt display.

Answer 1

in your code:

   case R.id.bClear:

       display.setText("");

you miss the break; sentence
