exListView.setAdapter(exlvAdapter);
//遍历所有group,将所有项设置成默认展开
intgroupCount = exListView.getCount();
for (inti=0; i
加一句代码如下:
settingLists.setGroupIndicator(this.getResources().getDrawable(R.layout.expandablelistviewselector));
或xml设置:
android:groupIndicator="@drawable/groupIndicator_selector"
大功告成
elistview.setGroupIndicator(null);//将控件默认的左边箭头去掉,
2在自定义的继承自BaseExpandableListAdapter的adapter中有一个方法
/** * 父类view */ @Override
public View getGroupView(intgroupPosition, booleanisExpanded, View convertView, ViewGroup parent)
{ Log.i("zhaoxiong","parent view");
LinearLayoutparentLayout=(LinearLayout) View.inflate(context, R.layout.wowocoupons_parent_item, null);
TextViewparentTextView=(TextView)parentLayout.findViewById(R.id.parentitem);
parentTextView.setText(parentlist.get(groupPosition));
ImageViewparentImageViw=(ImageView) parentLayout.findViewById(R.id.arrow);
//判断isExpanded就可以控制是按下还是关闭,同时更换图片
if(isExpanded){
parentImageViw.setBackgroundResource(R.drawable.arrow_down);
}else{
parentImageViw.setBackgroundResource(R.drawable.arrow_up); }
return parentLayout;
}
exList.setOnGroupExpandListener(new OnGroupExpandListener() {
@Override
public void onGroupExpand(int groupPosition) {
for (int i = 0; i < getData().size(); i++) {
if (groupPosition != i) {
exList.collapseGroup(i);
}
}
}
});
3.expandablelistview的Group点击事件,onGroupClick的返回值false展开,true不展开
tt_list.setOnGroupClickListener(new OnGroupClickListener() {
@Override
public boolean onGroupClick(ExpandableListView parent, View v,
int groupPosition, long id) {
IsFlag=true;
if(adapter.getGroupData().get(groupPosition).getList().size()==1){
Bundle b=new Bundle();
b.putInt("saveIndex", 0);
// b.putString("mac", mac);
// b.putString("deviceId", mDeviceId);
b.putSerializable("datalist", adapter.getGroupData().get(groupPosition).getList());
Intent i=new Intent(WappushBindingActivity.this,VideoPlayerActivity.class);
i.putExtras(b);
startActivity(i);
}
// int groupCount = tt_list.getCount();
// for (int i=0; i
