Hi, I'm trying to create a radio button group using the resources and recover it on my Activity code, but I'm receiving a NullPointerException when I do that.
Here is my xml code: <?xml version="1.0" encoding="UTF-8"?> > <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"; > android:orientation="vertical" android:layout_width="fill_parent" > android:layout_height="fill_parent"> > > <LinearLayout android:orientation="vertical" > android:layout_width="fill_parent" > android:layout_height="wrap_content" > android:layout_marginTop="10px"> > > <TextView android:layout_width="wrap_content" > android:layout_height="wrap_content" android:text="Share this > log:" /> > <RadioGroup androidid="@+id/shareOptionGroup" > android:layout_width="wrap_content" > android:layout_height="wrap_content" > xmlns:android="http://schemas.android.com/apk/res/android"; > android:orientation="horizontal"> > > <RadioButton androidid="@+id/realTimeButton" > android:layout_width="wrap_content" > android:layout_height="wrap_content" > android:text="Real Time" android:checked="false" > android:layout_gravity="left" android:layout_weight="0"> > </RadioButton> > <RadioButton androidid="@+id/afterSaveButton" > android:layout_width="wrap_content" > android:layout_height="wrap_content" > android:text="After Saving" android:checked="false" > android:layout_gravity="left" android:layout_weight="0"> > </RadioButton> > <RadioButton androidid="@+id/otherButton" > android:layout_width="wrap_content" > android:layout_height="wrap_content" > android:text="Do not share" android:checked="false" > android:layout_weight="0" android:layout_gravity="left"> > </RadioButton> > </RadioGroup> > > </LinearLayout> > </LinearLayout> And I recover it using: public void onCreate(Bundle savedInstanceState) { > super.onCreate(savedInstanceState); > setContentView(R.layout.config_xml); > group = Groupthis.findViewById(R.id.shareOptionGroup); > group.setOnCheckedChangeListener(this); > } when I run it, I receive a NullPointerException on * group.setOnCheckedChangeListener(this)*; Does anybody knows whys is it happening? --Valeriano --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
