Java 如何将侦听器附加到单选按钮

我有一个显示各种单选按钮的活动。单选按钮按放射组分组。我希望当某个单选按钮被选中时，某些单选按钮消失。当事故按钮被选中时，坠落、绊倒和疾病按钮消失。我怎样才能做到这一点

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

@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;
            }
        }

试着这样做：-

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()) {

        }
     }
});

您可以使用

setOnCheckedChangeListener

在

RadioGroup

上设置侦听器。

onCheckedChanged

回调接收

checkedd

参数中新选中按钮的ID

在您的情况下，只需向您的无线电组添加一个ID（以便从代码中检索）

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()) {

        }
     }
});

<RadioGroup
    android:id="@+id/category_group"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal" >

RadioGroup categoryGroup = (RadioGroup) findViewById(R.id.category_group);
categoryGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {

@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
    switch(checkedId) {
        case R.id.radioButtonincident:
            // 'Incident' checked
            fall.setVisibility(View.GONE);
            trip.setVisibility(View.GONE);
            illness.setVisibility(View.GONE);
            break;
        case R.id.radioButtonaccident:
            // 'Accident' checked
            break;
        case R.id.radioButtonconcern:
            // 'Concern' checked
            break;
        }
    }
});
