我有一个显示各种单选按钮的活动.单选按钮分组在单选组中.当检查某个radiobutton时，我想要一些radiobutton消失.例如，当事件按钮被选中时，跌倒、旅行和疾病单选按钮消失.我怎样才能做到这一点?

I have an activity that displays various radiobuttons. The radiobuttons are grouped in radiogroups. I want some of the radiobutton to disappear when a certain radiobutton is checked. eg when the incident button is checked the fall, trip and illness radiobutton disappear. how can i achieve this?

我有愚蠢的代码，但需要以某种方式将侦听器附加到事件按钮.

I have the foolowing code but need to somehow attach a listener to the incident button.

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.reportsomethinglayout);

         resolution = (EditText)findViewById(R.id.editTextresolution);
        // resolution.setInputType(InputType.TYPE_NULL);
        // showSoftKeyboard(resolution);



         accident  = (RadioButton)findViewById(R.id.radioButtonaccident);
         incident  = (RadioButton)findViewById(R.id.radioButtonincident);
         concern  = (RadioButton)findViewById(R.id.radioButtonconcern);
         fall  = (RadioButton)findViewById(R.id.radioButtonfall);
         trip  = (RadioButton)findViewById(R.id.radioButtonTrip);
         illness  = (RadioButton)findViewById(R.id.radioButtonillness);





    }



     public void onRadioButtonClicked(View view) {
            // Is the button now checked?
            boolean checked = ((RadioButton) view).isChecked();

            // Check which radio button was clicked
            switch(view.getId()) {
                case R.id.radioButtonaccident:
                    if (checked)
                        Log.e(TAG, "accident radiobutton checked");
                    break;
                case R.id.radioButtonincident:
                    if (checked)
                        Log.e(TAG, "incident radiobutton checked");

                            fall.setVisibility(View.GONE);
                            trip.setVisibility(View.GONE);
                            illness.setVisibility(View.GONE);
                    break;
            }
        }

推荐答案

试试这样:-

RadioGroup group = (RadioGroup) findViewById(R.id.radioGroup1);

group.setOnCheckedChangeListener(new OnCheckedChangeListener() {

    @Override
    public void onCheckedChanged(RadioGroup group, int checkedId) 
       {
        // TODO Auto-generated method stub
        if(radiobutton1.isChecked()) {
             fall.setVisibility(View.GONE);
             trip.setVisibility(View.GONE);
             illness.setVisibility(View.GONE);
        } else if(radiobutton2.isChecked()) {

        }
     }
});
