Android – Adding a list view inside a listitem

androidandroid-fragmentslistadapter

I am using list fragment with a list header and need to add a set of list inside the first list item.
something like following

I am using custom list adapter to load the list items. Now for List Item 1 – I need to add a subview on top of list item from within the list adapter. How should I go about this? I am not sure if expandable list item is what I wanna use here.

My custom adapter's getView looks something like this:

public View getView(int position, View convertView, ViewGroup parent) {
   ViewHolder holder = null;
   int type = getItemViewType(position);

   if (convertView == null) {
   holder = new ViewHolder();

   switch (type) {

    case TYPE_LIST_ITEM_1:
        convertView = mInflater.inflate(R.id.list_item_one, null);
        /* add code */                          
        /* add another list adapter? */
        break;

    case TYPE_LIST_ITEM_OTHERS:
        convertView = mInflater.inflate(R.layout.list_item_other, null);
        /* add code for below list */
        break;

    }
    convertView.setTag(holder);
   } 
   else {
    holder = (ViewHolder)convertView.getTag();
   }

   return convertView;
  }

What would be a optimal way of going about it, without losing the header view which uses

     myListView.addHeaderView(myHeaderView);

A ScrollView in a ScrollView isn't possible on Android without major bugs, Google says to not do it. You could have a LinearLayout inside of your list item (with its orientation set to vertical) and manually use addView() to add views to the LinearLayout that will be displayed with the layout's set orientation.

Java – custom listview adapter getView method being called multiple times, and in no coherent order

This is not an issue, there is absolutely no guarantee on the order in which getView() will be called nor how many times. In your particular case you are doing the worst thing possible with a ListView by giving it a height=wrap_content. This forces ListView to measure a few children out of the adapter at layout time, to know how big it should be. This is what provides ListView with the convertViews you see passed to getView() even before you scroll.

Java – Custom adapter, selected item background

you can use selector to highlight item

In drawable folder create a xml file

list_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" android:exitFadeDuration="@android:integer/config_mediumAnimTime">

    <item android:drawable="@color/blue" android:state_activated="true"/>
    <item android:drawable="@color/blue" android:state_selected="true"/>
    <item android:drawable="@color/transparent"/>

</selector>

and set listSelector in xml for your listview like

android:listSelector="@drawable/list_selector"

color.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <color name="BLACK">#000000</color>
    <color name="WHITE">#FFFFFF</color>
    <color name="light_grey">#a5acb0</color>
    <color name="brown">#525964</color>
    <color name="dark_grey">#212121</color>
    <color name="aqua">#a6b1ba</color>
    <color name="red_cherry">#C9282D</color>
    <color name="silver">#A9A9A9</color>
    <color name="black">#000000</color>
    <color name="transparent">#00000000</color>
    <color name="white">#FFFFFF</color>
    <color name="blue">#00aceb</color>
    <color name="spiritclips_bck">#8AB8E0</color>
    <color name="translucent_black">#55000000</color>
    <color name="grid_bck">#627583</color>
    <color name="grey">#393430</color>
    <color name="dark_grey_bg">#1f1c17</color>
    <color name="login_font_color_1">#546778</color>
    <color name="login_font_color_2">#8E8E8E</color>
    <color name="blue_txt">#0f5690</color>

</resources>

for custom_list_item the layout should be

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="?android:attr/activatedBackgroundIndicator" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="20sp"
        android:textStyle="bold" />

</LinearLayout>

and minimum version of your application should be 11
