取消选中RadioButton的替代方法

Question

是否有任何可能的方法通过在选中的RadioButton上签名来取消选中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); 

} 

好吧，现在我已经更新了它。这应该工作Philipz
