Android中RadioGroup的用法

Activity中设置RadioGroup的监听方法

        RadioGroup rGroupRepeated=(RadioGroup)findViewById(R.id.rGroup);
        eText=(EditText)findViewById(R.id.eText);
       
        RadioGroup.OnCheckedChangeListener rGroupChangeLisnter=new RadioGroup.OnCheckedChangeListener(){
            @Override
            public void onCheckedChanged(RadioGroup group, int checkedId){
                if(rGroupRepeated.getCheckedRadioButtonId()==R.id.rButtonOk){
                    eText.setEnabled(true);
                     isRepeated=true;
                }else {
                    eText.setEnabled(false);
                    isRepeated=false;
                }
            }
        };
        rGroupRepeated.setOnCheckedChangeListener(rGroupChangeLisnter);

XML中RadioGroup的布局

    android:id="@+id/rGroup"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:checkedButton="@+id/rButtonCancel">
         android:id="@+id/rButtonOk"
     android:text="@string/Ok"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     />
         android:id="@+id/rButtonCancel"
     android:text="@string/Cancel"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     />
