How to set editText visible/invisible?

In my program I want to be able to hide the edit text when a radio button is check and then reappear when the user clicks the other radio button.

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.waist2height); {
        final EditText h = (EditText)findViewById(R.id.editText2);          
        final RadioButton rCM = (RadioButton) findViewById(R.id.radioCM);
        final RadioButton rFT = (RadioButton) findViewById(R.id.radioFT);                       
        if(rCM.isChecked()){    
            h.setVisibility(View.VISIBLE);              
        }
        else if(rFT.isChecked()){               
            h.setVisibility(View.INVISIBLE);
        }}

The code below is where i have the problem i only added in the relevant part of my code instead of the entire thing 

if(rCM.isChecked()){                    
    h.setVisibility(View.VISIBLE);                  
}
else if(rFT.isChecked()){                   
    h.setVisibility(View.INVISIBLE);
}

Unfortunately I can't seem to get it to work. Am I missing anything? Or have I got it all wrong altogether? I have tried h.setVisibility(View.GONE); however it just ruines the format of the xml.

Try this :

rCM.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
    h.setVisibility(View.VISIBLE);
}
});
rFT.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
    h.setVisibility(View.INVISIBLE);              
}
});

I've made a sample and it works for me just take a look at this code :

I've declared those variables as global 

RadioButton rb1,rb2;
TextView tbHideOrNot;

Then in my onCreate() I've got this :

 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    rb1 = (RadioButton)findViewById(R.id.rb1);
    rb2 = (RadioButton)findViewById(R.id.rb2);
    tbHideOrNot = (TextView)findViewById(R.id.textView);
    rb1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            if(isChecked){
                tbHideOrNot.setVisibility(View.INVISIBLE);
                rb2.setChecked(false);
            }
        }
    });
    rb2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            if(isChecked){
                tbHideOrNot.setVisibility(View.VISIBLE);
                rb1.setChecked(false);
            }
        }
    });

}

In my opinion, that's not a good idea use a RadioButton for the use that you want, I recommend you to use CheckBox cause you can only click ONE and this you have to check if the first RadioButton is clicked and you press the second one you'll have to uncheck the first, etc... well It's your code I'm only giving to you an advice, this code is working for me, let me know if it works for you :)

By the way if you want to use this code : 

if(rCM.isChecked()){                    
 h.setVisibility(View.VISIBLE);                  
}
else if(rFT.isChecked()){                   
 h.setVisibility(View.INVISIBLE);
}

It's fine but you only will hide or not the TextView when you start the Activity and you'll have to put any RadioButton (if you want) android:checked="true" or false if you want to be showed or not the TextView, but with this code you won't get the click event on the RadioButtons.

RadioGroup radioGroup = (RadioGroup) findViewById(R.id.yourRadioGroup);        
    radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() 
    {
        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            if(checkedId==0){

                h.setVisibility(View.VISIBLE);

            }
            else if(checkedId==1){

                h.setVisibility(View.INVISIBLE);
            } 
        }
    });
