android - why disabled item is still checkable in listview -


i want listview items , of them checked. if first item not checked other item not enabled, of course, should not checkable @ time. extend listview mylistview this:

public class mylistview extends listview {  public mylistview(context context) {     super(context);     init(); }  public mylistview(context context, attributeset attrs) {     super(context, attrs);     init(); }  public mylistview(context context, attributeset attrs, int defstyle) {     super(context, attrs, defstyle);     init(); }  private void init() {     setadapter(new arrayadapter<string>(getcontext(), android.r.layout.simple_list_item_multiple_choice,array ));     setchoicemode(choice_mode_multiple);      setonitemclicklistener(new onitemclicklistener() {         @override         public void onitemclick(adapterview<?> parent, view view, int position,                 long id) {              sparsebooleanarray posarray = getcheckeditempositions();             boolean bchecked = false;             if( null != posarray ) {                 for( int = 0; < posarray.size(); i++ ) {                     int nidx = posarray.keyat(i);                     if( nidx == 0 ) {                         bchecked = posarray.get(nidx);                         break;                     }                 }             }              if( position == 0 ) {                 bchecked = !bchecked;                  for( int = 1; < array.length; i++ ) {                     getchildat(i).setenabled(!bchecked);                 }             }          }     }); }  private string[] array = { "test1", "test2", "test3", "test4" };  

}

and got problem: disabled items still checkable, there wrong? how should it? thanks.


actually,the problem done pawan yadav's suggestion. bellow code, wish meet same problem.

activity_main.xml:

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:id="@+id/parentlayout"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:paddingbottom="@dimen/activity_vertical_margin"     android:paddingleft="@dimen/activity_horizontal_margin"     android:paddingright="@dimen/activity_horizontal_margin"     android:paddingtop="@dimen/activity_vertical_margin"     tools:context=".mainactivity" >  </relativelayout> 

in activity's oncreate method:

listview listview = new listview(this); string [] datas = new string[36]; // generate data here  final boolean [] status = new boolean[36]; // generate check status here   final myadapter adapter = new myadapter(datas, status);  listview.setadapter(adapter );  listview.setonitemclicklistener(new onitemclicklistener() {      @override     public void onitemclick(adapterview<?> parent, view view, int position,             long id) {         if( position== 0 || status[0] ) {             status[position] = !status[positioin];             adapter.notifydatasetchanged();         }     } }); relativelayout parentlayout = (relativelayout)findviewbyid(r.id.parentlayout); parentlayout.addview(listview); 

listview_checkedtextview.xml:

<?xml version="1.0" encoding="utf-8"?> <checkedtextview xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@android:id/text1"     android:layout_width="match_parent"     android:layout_height="?android:attr/listpreferreditemheightsmall"     android:textappearance="?android:attr/textappearancelistitemsmall"     android:gravity="center_vertical"     android:checkmark="?android:attr/listchoiceindicatormultiple"     android:paddingstart="?android:attr/listpreferreditempaddingstart"     android:paddingend="?android:attr/listpreferreditempaddingend" /> 

activity's inner class:

private class myadapter extends baseadapter{ public myadapter( final string [] datas, final boolean [] status ) {     this.datas = datas;     this.status = status;     inflater = layoutinflater.from(mainactivity.this); }  @override public int getcount() {     return datas.length; }  @override public object getitem(int position) {     return position; }  @override public long getitemid(int position) {     return position; }  @override public view getview(int position, view convertview, viewgroup parent) {     if( null == convertview ) {         convertview = inflater.inflate(r.layout.listview_checkedtextview, null);         convertview = convertview.findviewbyid(r.id.text1);     }       checkedtextview checkedtextview = (checkedtextview) convertview;     checkedtextview.settext(datas[position]);     checkedtextview.setchecked(status[position]);     checkedtextview.setenabled( position == 0 ? true : status[0]);      return convertview; }  private string [] datas; private boolean [] status; private layoutinflater inflater; } 

you need call setclickable(boolean) make not clickable instead of setenabled(boolean)
