有没有办法通过克隆选中的RadioButton取消选中RadioButton？

Answer 1

RadioGroup radioGroup;
RadioButton radioButton1;
RadioButton radioButton2;
RadioButton radioButton3;

boolean hack = false;

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    radioGroup = (RadioGroup) findViewById(R.id.rg);
    radioButton1 = (RadioButton) findViewById(R.id.r1);
    radioButton2 = (RadioButton) findViewById(R.id.r2);
    radioButton3 = (RadioButton) findViewById(R.id.r3);

    OnClickListener radioClickListener = new OnClickListener()
    {

        public void onClick(View v)
        {
            if (v.getId() == radioGroup.getCheckedRadioButtonId() && hack)
            {
                radioGroup.clearCheck();
            }
            else
            {
                hack = true;
            }
        }
    };

    OnCheckedChangeListener radioCheckChangeListener = new OnCheckedChangeListener()
    {

        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)
        {
            hack = false;
        }
    };

    radioButton1.setOnCheckedChangeListener(radioCheckChangeListener);
    radioButton2.setOnCheckedChangeListener(radioCheckChangeListener);
    radioButton3.setOnCheckedChangeListener(radioCheckChangeListener);

    radioButton1.setOnClickListener(radioClickListener);
    radioButton2.setOnClickListener(radioClickListener);
    radioButton3.setOnClickListener(radioClickListener);

}

好了,我已经更新了.这应该适用菲利普斯
