Java – Android unchecking radio buttons

androidjavaradio-button

I have this 3 Radio buttons, let's assume radio1, radio2, radio3. What i did is if i checked radio1 and radio2, the radio3 will be uncheckable and so on. So i can only check 2 buttons at a time.

Then i made this button that if i clicked it, it will unchecked all the checked radio buttons. Now what my problem is whenever i try to check radio1 and radio2 and clear it. The radio3 still won't be clickable even if the radio1 and 2 aren't checked anymore. 

RadioButton radio1;
RadioButton radio2;
RadioButton radio3;
Button clear;
TextView tv;

protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.secondxml);
radio1 = (RadioButton) findViewById(R.id.rd1);
radio2 = (RadioButton) findViewById(R.id.rd2);
radio3 = (RadioButton) findViewById(R.id.rd3);
radio1.setOnCheckedChangeListener(this);
radio2.setOnCheckedChangeListener(this);
radio3.setOnCheckedChangeListener(this);
tv = (TextView) findViewById(R.id.tv);
clear = (Button) findViewById(R.id.clear);
clear.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View arg0) {
        // TODO Auto-generated method stub
    radio1.setChecked(false);
    radio2.setChecked(false);
    radio3.setChecked(false);
    tv.setText("");
    }
});
}

@Override
public void onCheckedChanged(CompoundButton arg0, boolean arg1) {
    // TODO Auto-generated method stub
    if(radio1.isChecked() && radio2.isChecked()){
        tv.setText("Radio1 and 2 is checked ");
        radio3.setClickable(false);
    }
    if(radio1.isChecked() && radio3.isChecked()){
            radio2.setClickable(false);
        tv.setText("radio 1 and 3 is checked");

    }
    if(radio2.isChecked() && radio3.isChecked()){
        radio1.setClickable(false);
        tv.setText("radio2 and 3 is checked");

    }
}

}

Best Answer

You have therefore set radio3 to not be clickable by calling radio3.setClickable(false); when you selected radio1 and radio2. Your clear button doesn't reverse this.

I suggest in your onClick(...) method for your clear OnClickListener you call

radio1.setClickable(true);
radio2.setClickable(true);
radio3.setClickable(true);

this would stop them being disabled when you clear the selection, bringing them back to the default state.
