java– 如何将侦听器附加到单选按钮

我有一个显示各种radiobutton的活动.无线电按钮分组在无线电组中.我希望在检查某个单选按钮时,一些radiobutton会消失.例如,当检查事故按钮时,摔倒,绊倒和疾病的无线电按钮消失.我怎么能实现这个目标？

我有愚蠢的代码,但需要以某种方式将监听器附加到事件按钮.

@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;            }        }

解决方法:

试试这样： –

RadioGroup group = (RadioGroup) findVIEwByID(R.ID.radioGroup1);group.setonChecked@R_419_1962@(new OnChecked@R_419_1962@() {    @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()) {        }     }});
