单选按钮未取消选择

Question

Here is my code, I want to unselect a radio button when I click on it again. Since I have some code that only works when none of the radiobuttons are selected.

    if (TablesOn == true) {
        TablesOn = false;
    } else {
        TablesOn = true;
    }

    if (jRadioButton1.isVisible()==true) {
      jRadioButton1.setVisible(false);
      jRadioButton2.setVisible(false);
      jRadioButton3.setVisible(false);
      jLabel3.setVisible(false);
      jLabel4.setVisible(false);
      jLabel5.setVisible(false);
    } else {
      jRadioButton1.setVisible(true);
      jRadioButton2.setVisible(true);
      jRadioButton3.setVisible(true);
      jLabel3.setVisible(true);
      jLabel4.setVisible(true);
      jLabel5.setVisible(true);
    }

Answer 1

To deselect a RadioButton which is inside of RadioGroup and be able to then select it again, firstly get your RadioGroup :

RadioGroup rg = (RadioGroup) findViewById(R.id.your_radio_group_name_in_layout);

And then do:

rg.check(-1);

Of course, you need some code to save last checked button number, and if it is pressed again, deselect it using the code above.
