Preventing Negative Numbers in TextView
<p>I have a TextView that displays a number (in this case, the number is 10). </p>

<p>Now, i have a button so the user has to press that button 10 times in order for the number to hit 0, resulting in moving on to the next level. However, </p>

<p>I can keep hitting that button and it starts its way back into the negatives (-1, -2, etc.). </p>

<p>I tried to think of how I would prevent this but I'm at loss.. any ideas?</p>

<p>-----------------------------------EDIT-----------------------------------------</p>

<p>Okay, so here is my update (I got it to stop at 0):</p>

<pre><code>public void onClick(View v) {
        // TODO Auto-generated method stub

        if (scr &gt;= 1) {

            scr = scr - 1;
           TextView Score = (TextView) findViewById(R.id.Score);
           Score.setText(String.valueOf(scr));
        }

        if (scr == 10) 
        {
               aCounter.start();
        }

        if (scr == 1) 
        {
            aCounter.cancel();
            new AlertDialog.Builder(Tap_Game_Activity.this)
             .setTitle("Congratulations!").setMessage("Go to Level 2?")
             .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
              public void onClick(DialogInterface AlertDialog, int PositiveButton) {
                  setContentView(R.layout.activity_level02_activity);
              }
               })
             .setNegativeButton("No", new DialogInterface.OnClickListener() {
                  public void onClick(DialogInterface AlertDialog, int NegativeButton) {
                   }
                   }).show();
        }

    }});
</code></pre>

<p>}</p>

<p>(EDIT!): I fixed the AlertDialog by changing the 2 'Else If' statements to just 'If' statements. However, my timer still doesn't work :(, any help?</p>
