Android: How Do I Enable/disable A Checkbox, Depending On A Radio Button Being Selected First

Basically I have a Radio Group with two radio buttons, one of them is labelled RUN and the other is labelled PASS. Just underneath this I also have a check-box labelled 'Pass Compl

Solution 1:

I've managed to answer my question with a little more research, may help others as well...

privatevoidinitialize() {
    // TODO Auto-generated method stub
        RadioGroup1 = (RadioGroup) findViewById(R.id.runandpass);
        Radio1 = (RadioButton) findViewById(R.id.radiobuttonrun);
        Radio2 = (RadioButton) findViewById(R.id.radiobuttonpass);
        checkBoxcmpltpass = (CheckBox) findViewById(R.id.checkBoxcmpltpass);
        RadioGroup1.setOnCheckedChangeListener(this);
}


 publicvoidonCheckedChanged(RadioGroup group, int checkedId) {
    // TODO Auto-generated method stubswitch(checkedId){
    case R.id.radiobuttonrun:
        checkBoxcmpltpass.setEnabled(false);
    break;

    case R.id.radiobuttonpass:
        checkBoxcmpltpass.setEnabled(true);
    break;
    }
}

Solution 2:

try this :

        mRadioGroup1 = (RadioGroup) findViewById(R.id.runandpass);
        mRadio1 = (RadioButton) findViewById(R.id.radiobuttonrun);
        mRadio2 = (RadioButton) findViewById(R.id.radiobuttonpass);
        mcheckBoxcmpltpass= (RadioButton) findViewById(R.id.checkBoxcmpltpass);
        /*RadioGroup?OnCheckedChangeListener???*/
        mRadioGroup1.setOnCheckedChangeListener(mChangeRadio);
      }
      private RadioGroup.OnCheckedChangeListenermChangeRadio=newRadioGroup.OnCheckedChangeListener()
      {
        @OverridepublicvoidonCheckedChanged(RadioGroup group, int checkedId)
        {
          // TODO Auto-generated method stubif(checkedId==mRadio1.getId())
          {
            /*?mRadio1*/
           mcheckBoxcmpltpass.disabled=false;
          }
          elseif

(checkedId==mRadio2.getId())
      {
        /*?mRadio2*/
        mcheckBoxcmpltpass.disabled=true;
      }      
    }
  }; 

Solution 3:

Use Radiogroup.setOnCheckedChangeListener, then on checked change use checkbox.setenable

Solution 4:

You probably will want to add a listener to your checkbox, that will check for the selection and update the other views as needed.

 captureGrp = (RadioGroup) findViewById(R.id.runandpass);
 myRadio1 = (RadioButton) findViewById(R.drawable.radio1);
 myRadio2 = (RadioButton) findViewById(R.drawable.radio2);
 myRadio3 = (RadioButton) findViewById(R.drawable.radio3);

 captureGrp.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {

     publicvoidonCheckedChanged(RadioGroup group, int checkedId) {


            if (checkedId == R.id.radio1) {
                //disable and enable as needed
            } elseif (checkedId == R.id.radio2) {
                // disable as needed
            } else {
                // add as many as you need
            }
        }

Solution 5:

try this

finalCheckBoxcl_chk= (CheckBox) view.findViewById(R.id.cl_chk);
  cl_chk.setEnabled(false);

This will help you out...
