Question

我正在expandablelistview上打开标题，然后子标题。但是，当我单击副标题时，它应该打开新活动。

请在这里帮助我，而不是单击显示子项的吐司。

private OnChildClickListener myListItemClicked =  new OnChildClickListener() {

    public boolean onChildClick(ExpandableListView parent, View v,
                                int groupPosition, int childPosition, long id) {

        //get the group header
        HeaderInfo headerInfo = SectionList.get(groupPosition);
        //get the child info
        DetailInfo detailInfo =  headerInfo.getProductList().get(childPosition);
        //display it or do something with it
        Toast.makeText(getBaseContext(), "Clicked on Detail " + headerInfo.getName()
                + "/" + detailInfo.getName(), Toast.LENGTH_LONG).show();
        return false;
    }
};

将ThisActivity替换为您当前的活动，并将YourNewActivity替换为您要进行的新活动

private OnChildClickListener myListItemClicked = new OnChildClickListener() {

    public boolean onChildClick(ExpandableListView parent, View v,
                                int groupPosition, int childPosition, long id) {

        //get the group header
        HeaderInfo headerInfo = SectionList.get(groupPosition);
        //get the child info
        DetailInfo detailInfo =  headerInfo.getProductList().get(childPosition);
        //display it or do something with it
        Toast.makeText(getBaseContext(), "Clicked on Detail " + headerInfo.getName()
                + "/" + detailInfo.getName(), Toast.LENGTH_LONG).show();

    switch(childPosition) {
    case 0:
        Intent intent = new Intent(ThisActivity.this, YourNewActivity0.class);
        break;
    case 1:
        Intent intent = new Intent(ThisActivity.this, YourNewActivity1.class);
        break;
    case 2:
        Intent intent = new Intent(ThisActivity.this, YourNewActivity2.class);
        break;
}

    startActivity(intent);
        return false;
    }
};
