disable checkbox after checked, android

Question

I want to achieve this : user check on a unchecked checkbox, a toast displayed, the checkbox then become disable..

male.setOnCheckedChangeListener(new OnCheckedChangeListener(){

    @Override
    public void onCheckedChanged(CompoundButton arg0, boolean isChecked) {
   // TODO Auto-generated method stub
   if (isChecked){
    Toast.makeText(CheckBoxTuts.this, "male" , Toast.LENGTH_SHORT).show();
    male.setChecked(false);

   }
    }

       });

the output failed, because they execute on the same time, even I put the male.setChecked(false) outside.. I can't recall there's something to run something 1st, then other thing.. is it thread? really cant remember

If you want to achieve: "user check on a unchecked checkbox, a toast displayed, the checkbox then become disable..",you should try this code:

male.setOnCheckedChangeListener(new OnCheckedChangeListener(){

    @Override
    public void onCheckedChanged(CompoundButton arg0, boolean isChecked) {                   
      if (isChecked){
          Toast.makeText(CheckBoxTuts.this, "male" , Toast.LENGTH_SHORT).show();
          male.setEnabled(false); // disable checkbox 
      }
    }    
});

i used ur code to check whether its working but setEnabled(false) doesn't work. – Terril Thomas Oct 03 '12 at 05:33
@ErrorHandler: its not an invalid method,so how it can't work? what's the problem you are facing? – Hiral Vadodaria Oct 03 '12 at 05:34
It stays Checked even though setenabled is false – Terril Thomas Oct 03 '12 at 05:38
@ErrorHandler: it disables checkbox,that doesn't mean changing status of checkbox.it would remain checked only.it would just don't let you change its state once it gets into "checked" state. – Hiral Vadodaria Oct 03 '12 at 05:39
so even the SetChecked(false) works since its gives false while u debug – Terril Thomas Oct 03 '12 at 05:42

@ErrorHandler: he wanted to disable checkbox,not to get it "unchecked"..and you can't disable checkbox using setChecked(false).it changes status of checkbox to false. please read doc and question for more info. – Hiral Vadodaria Oct 03 '12 at 05:43

Try this....

- Use the setEnabled(false) on the CheckBox

male.setOnCheckedChangeListener(new OnCheckedChangeListener(){

    @Override
    public void onCheckedChanged(CompoundButton arg0, boolean isChecked) {                   
      if (isChecked){

          Toast.makeText(CheckBoxTuts.this, "male" , Toast.LENGTH_SHORT).show();

          male.setEnabled(false);   // Will Disable checkbox 
      }
    }    
});

Try to use .onClickListener(View.OnClickListener) with implemented View.OnClickListener. In body of implemented method you will check if the CheckBox is checked or not and set them.

Ohh in fact. To set enabled/disabled state you need to used View.setEnabled(boolean). – Pawel Oct 03 '12 at 04:52
Using View.setVisibilty(int) will set if the component is showing or not. – Pawel Oct 03 '12 at 04:53
You need to check if the checkBox is checked with method `CheckBox.isChecked()`. – Pawel Oct 03 '12 at 14:34

   if (isChecked){
   Toast.makeText(CheckBoxTuts.this, "male" , Toast.LENGTH_SHORT).show();
    //male.setVisibility(View.GONE);//disappear your check box
    male.setEnabled(false);//disable your check box
}
}

First , Register Your CheckBox to OnCheckedChangeListener.

chk.setOnCheckedChangeListener(this);

then, Overrides it's Method

 @Override
    public void onCheckedChanged(CompoundButton compoundButton, boolean b)
    {
        if (chk.isChecked())
        {
           chk.setEnabled(false);
        }
    }
