一次只能选择一个单选按钮

Question

我在收音机组中有两个单选按钮.我还有2个androd:按钮复选框 - 用于取消选择单选按钮时的复选框,以及用户选择复选框时的checkbox_v.我也implemnted一个方法onRadioButtonClick,以确保只有一个单选按钮有绘制:复选框和其他已checkbox_v.我怎样才能实现onRadioClick来做到这一点？任何的想法？

public void onRadioButtonClick(View v)
{
    RadioButton button = (RadioButton) v;
    boolean checkBox1Selected;
    boolean checkBox2Selected = false;

    Toast.makeText(MainActivity.this,
        button.getId()+ " was chosen."+R.id.wificheckBox,
        Toast.LENGTH_SHORT).show();

    if ( button.getId() ==R.id.wificheckBox) {
        // Toggle status of checkbox selection
        checkBox1Selected = radiowifiButton.isChecked();

        // Ensure that other checkboxes are not selected
        if (checkBox2Selected) {
            radiomobileButton.setChecked(false);
            checkBox2Selected = false;
        }
        else if (button.getId() ==R.id.wifimobilecheckBox) {
            // Toggle status of checkbox selection
            checkBox2Selected = radiomobileButton.isChecked();
            // Ensure that other checkboxes are not selected
            if (checkBox1Selected) {
                radiowifiButton.setChecked(false);
                checkBox1Selected = false;
            }
        }
    }

如果它们在放射组中,则一次只能选择一个.如果您希望两者都能被选中,请从放射组中删除它们.
