Android Learning Notes---Get selected values for Radiogroup

1, Get Radiogroup control: Radiogroup radiogroup = (radiogroup) Findviewbyid (R.id.myradiogroup);

2, get RadioButton control; RadioButton RadioButton = (RadioButton) Findviewbyid (Radiogroup.getcheckedradiobuttonid ());

3, gets the value of the selected radio: String text = Radiobutton.gettext (). toString ();

4, add a listener event for Radiogroup to listen for event response inside the component: Radiogroup.setoncheckedchangelistener (New Radiogroup.oncheckedchangelistener ( {@Override public void oncheckedchanged (radiogroup group, int checkedid) {//In this function is used to change the value of the selected RadioButton and/or any Please refer to the following selectradiobtn (); } });

5, in the oncreat need to initialize the above four information;

6, the overall use of the sample: protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);                 Setcontentview (R.layout.waterselect);         Getviews (); Setlistenerforview (); }

private void Getviews () {//Get Radio component information for water inside the library, Radiogroup = (radiogroup) Findviewbyid (r.id.iswaterbycontent); }

private void Setlistenerforview () {//Select Radio Selectradiobtn (); Monitoring Event Radiogroup.setoncheckedchangelistener (new Radiogroup.oncheckedchangelistener () {@Override public void for Sheung Shui in the vault  OnCheckedChanged (radiogroup Group, int checkedid) {selectradiobtn (); }  }); }

private void Selectradiobtn () {RadioButton = (RadioButton) Findviewbyid (Radiogroup.getcheckedradiobuttonid ());    Waterin = Radiobutton.gettext (). toString ();     LOG.I ("Radio", Waterin); }
