jak dołączyć słuchacza do przycisku radiowego

Question

Mam aktywność, która wyświetla różne radiobuttons. Radiobuttony są pogrupowane w radiologie. Chcę, aby część radiobuttonu zniknęła, gdy zostanie sprawdzony pewien radiobutton. np. gdy przycisk incydentu jest sprawdzany, znika sygnał radiowy upadku, podróży i choroby. Jak mogę to osiągnąć?

Mam kod foolowing, ale trzeba jakoś dołączyć słuchacza do przycisku incydentu.

@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; 
      } 
     }

Answer 1

spróbuj tak: -

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()) { 

     } 
    } 
}); 

Answer 2

Można ustawić słuchacza na RadioGroup z setOnCheckedChangeListener. Wywołanie zwrotne onCheckedChanged otrzymuje identyfikator nowo sprawdzonego przycisku w parametrze checkedId.

W Twoim przypadku, wystarczy dodać identyfikator do grupy radiowej (w celu pobrania go z kodu)

<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" > 

I użyć następującego kodu:

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; 
     } 
    } 
});
