You seem to have a logical issue here. You are removing the item and updating the listView, which is correct, but you are not changing the actual List List<RowItem> rowItems; beyond the current scope. When you select HomeFragment again, you are creating a new instance and everything resets.
One solution might be to pass the data from the updated List<RowItem> rowItems; to the next Fragment so that the changes you made are reflected in other Fragments.
Currently, you create your List<RowItem> rowItems by piecing together the following:
member_names = getResources().getStringArray(R.array.Member_names);
product_icons = getResources().obtainTypedArray(R.array.product_icons);
statues = getResources().getStringArray(R.array.statues);
However, when you remove the RowItem from the list, you don't change any of those three variables. Thus, when the new instance of the Fragment is initialized, you create a brand new List of RowItems using the same old data.
In short, here are two possible solutions:
Update the variables member_names, product_icons, statues when you remove the item from the list
Pass the List of RowItem between the Fragments

this is my adapter
#Override

convertView = mInflater.inflate(R.layout.drawer_list_item, null);

ImageView imgIcon = (ImageView) convertView.findViewById(R.id.icon);
TextView txtTitle = (TextView) convertView.findViewById(R.id.title);
final CheckBox ch = (CheckBox) convertView.findViewById(R.id.checkBox);
imgIcon.setImageResource(navDrawerItems.get(position).getIcon());
txtTitle.setText(navDrawerItems.get(position).getTitle());

}
});
// displaying count
// check whether it set visible or not
if(navDrawerItems.get(position).getCounterVisibility()){
}else{
// hide the counter view
}
return convertView;
}
Define one Interface class:
public Interface OnChckBoxClickListener
{
public void onCheckBoxClick(int position, boolean isChecked);
}
After that create object of interface in adapter, see following code:
adapter = new NavDrawerListAdapter(getApplicationContext(),
navDrawerItems, new OnCheckBoxClickLisener()
{
public void OnCheckBoxClick(int position, boolean isChecked)
{
//print here position and isChecked
// also do here code what you want
}
});
After that registered listener in constructor of adapter:
public NavDrawerListAdapter(Context conext, ArrayList<NavDrawerItem> navDrawerItems, OnCheckBoxClickLisener listener)
{
this.context = context;
this.navDrawerItems = navDrawerItems;
this.lisetner = listener;
}
Then set Listener to OnClickOfCheckBox in getView:
ch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
boolean ans = ch.isChecked();
//navDrawerItems.get(position).setCounterVisibility(ans);
listener.OnCheckBoxClick(position, ans);
Toast.makeText(context,String.valueOf(ch.isChecked()),Toast.LENGTH_LONG).show();
}
});

orderFragment.setArguments(bundle);

I think your problem can be traced to this block of code:
public void onClick(DialogInterface dialog, int which) {
orderList.add(myString);
Toast.makeText(getActivity(), orderList+"", Toast.LENGTH_LONG).show();
OrderFragment orderFragment = new OrderFragment();
Bundle bundle = new Bundle();
bundle.putStringArrayList(ORDER_KEY, orderList);
orderFragment.setArguments(bundle);
dialog.cancel();
}
You are trying to create an OrderFragment as a result of the dialog button being clicked. However, since you are not attaching this instance to the activity, the arguments are never set. In the displayView() method you have this:
case 11:
fragment = new OrderFragment();
Basically, the fragment that you have doesn't have any arguments set - this is why you can't see them afterwards.
To deal with this, I can suggest you take a couple of steps:
Implement a proper fragment - fragment communication. Bear in mind that fragments should never communicate directly to one another (except if they are nested, but this is not your case). It would be better if you organize this through the activity - BakeFragment gets the orders, sends them to the activity and the activity sets them as arguments of the OrderFragment. You can get a nice example and more info on this approach here: http://developer.android.com/training/basics/fragments/communicating.html
Reorganize your displayView() method. Currently, you are going to force the creation of a new instance of the desired fragment each time you invoke this method. This can lead to undesired behavior - poor performance, strange state of the back stack, etc. Further more, you won't be able to benefit from the automatic saving of fragment parameters when fragments get recreated. I suggest you make use of tags and firstly check if the fragment, you want to show, is already there.
FragmentManager fm = getSupportFragmentManager();
Fragment fragment = fm.findByTag(THE_FRAGMENT_TAG);
if (fragment == null) {
// logic to create a fragment instance
}
// logic to show the fragment
The only time I see your OrderFragment used in a FragmentTransaction is when it is created in your MainActivity displayView method. There, it has no arguments set on it.
Your BakeFragment does create an OrderFragment and set its arguments, but it is never added through a FragmentTransaction and goes out of scope as soon as your onClick(DialogInterface dialog, int which) method is done executing. Therefore the OrderFragment with arguments set is never used.
Did you mean to show this fragment to the user through the use of a FragmentTransaction? If so, you could have BakeFragment define an interface with a method that indicates to the listener that the user either decided to create an order or cancelled. Have MainActivity implement this interface and register itself as a listener on your BakeFragment.
PS: Why is your logic seemingly reversed with your AlertDialog negative and positive button click handlers?
I have Navigation Drawer and all is ok. but i want add header. In this case i receive this error when i clicked in the Last element of the drawer.
java.lang.ArrayIndexOutOfBoundsException: length=9; index=9

and SlideMenuClickListener implements ListView.OnItemClickListener and lauch displayView method.
displayView method code this is:

Edit
This is NavDrawerListAdapter code:
public class NavDrawerListAdapter extends BaseAdapter{

txtCount.setText(navDrawerItems.get(position).getCount());
}else{
// hide the counter view
txtCount.setVisibility(View.GONE);
}
return convertView;
}
}
Edit
SlideMenuClickListener code is:
/**

private class SlideMenuClickListener implements
ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// display view for selected nav drawer item
displayView(position);
}
}
Solved.
The error is in this line (displayVIew method):
setTitle(navMenuTitles[position])
Solution is:
setTitle(navMenuTitles[position-1])

txtTitle.setText(navDrawerItems.get(position).getTitle());
// displaying count
// check whether it set visible or not
if(navDrawerItems.get(position).getCounterVisibility()){
txtCount.setText(navDrawerItems.get(position).getCount());
}else{
// hide the counter view
txtCount.setVisibility(View.GONE);
}
return convertView;
}
xml for header :

Only one thing comes to mind seeing this. ListView headers. Make diffrent Layout for header, inflate it and then set it to your listview
LayoutInflater inflater = (LayoutInflater) MainActivity.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view= inflater.inflate(R.layout.my_header_layout, null);
mDrawerList.addHeaderView(view);
While inflating header you can set OnClickListener if you need one
Overview::
I have a navigation drawer
I am setting the textView color in the adapter when position is 0
to red
On selecting different element in the list that textView is set to
red and others to black
So at anytime only one textview must be set in red(selected
adapter) others in black
Also to note that the reason i am setting red for textview in
adapter when position is o because since its the first fragment shown when it is loaded for the first time
This must be un-selected when i am selecting other adapter which is not
happening
Code i use is::
private class SlideMenuClickListener implements
ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// display view for selected nav drawer item
displayView(position);
setNavDrawerItemNormal();
title=(TextView) view.findViewById(R.id.title);
title.setTextColor(getApplicationContext().getResources().getColor(R.color.red));
}
}
public void setNavDrawerItemNormal()
{
for (int i=0; i< mDrawerList.getChildCount(); i++)
{
View v = mDrawerList.getChildAt(i);
TextView txtview = ((TextView) v.findViewById(R.id.title));
txtview.setTextColor(getApplicationContext().getResources().getColor(R.color.black));

NOTE:: I Can achieve my objective with application variable, but i am trying to do without it, programatically
The main idea that You don't need to have any additional variables in adapter / activity, because Android component already have one for lists with single choice. The following solution works fine in your case:
Assume your layout (activity_main.xml):
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- The navigation drawer -->
<GridView android:id="#+id/list_slidermenu"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#111"/>
</android.support.v4.widget.DrawerLayout>
Please note android:choiceMode="singleChoice" - that property will let the list track selected item by itself.
Remove all color setting code from the activity. Instead, use setChecked() to let the list know which item is selected:
public class MainActivity extends ActionBarActivity {
private static final String TAG = "MainActivity";
private DrawerLayout mDrawerLayout;
private GridView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
// nav drawer title
private CharSequence mDrawerTitle;
// used to store app title
private CharSequence mTitle;
// slide menu items
private String[] navMenuTitles;
private TypedArray navMenuIcons;
private ArrayList<NavDrawerItem> navDrawerItems;
private NavDrawerListAdapter adapter;
private TextView title;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTitle = mDrawerTitle = getTitle();
// load slide menu items
navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);
// nav drawer icons from resources
navMenuIcons = getResources()
.obtainTypedArray(R.array.nav_drawer_icons);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (GridView) findViewById(R.id.list_slidermenu);
navDrawerItems = new ArrayList<NavDrawerItem>();
// Recycle the typed array
navMenuIcons.recycle();
mDrawerList.setItemChecked(0, true); // NOTE: Set 0 item as checked!
mDrawerList.setOnItemClickListener(new SlideMenuClickListener());
// setting the nav drawer list adapter
adapter = new NavDrawerListAdapter(getApplicationContext(), navDrawerItems);
mDrawerList.setAdapter(adapter);
// enabling action bar app icon and behaving it as toggle button
getActionBar().setDisplayHomeAsUpEnabled(true);
//getActionBar().setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
android.R.drawable.ic_input_delete, //nav menu toggle icon
R.string.app_name, // nav drawer open - description for accessibility
R.string.app_name // nav drawer close - description for accessibility
) {
public void onDrawerClosed(View view) {
getActionBar().setTitle(mTitle);
// calling onPrepareOptionsMenu() to show action bar icons
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle(mDrawerTitle);
// calling onPrepareOptionsMenu() to hide action bar icons
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
if (savedInstanceState == null) {
// on first time display view for first nav item
displayView(0);
}
}
/**
* Slide menu item click listener
* */
private class SlideMenuClickListener implements ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
displayView(position);
// NOTE: new item is checked now
mDrawerList.setItemChecked(position, true);
}
}
...
}
In the adapter - just check if item is checked or not and set corresponding test color:
public class NavDrawerListAdapter extends BaseAdapter {
private Context context;
private ArrayList<NavDrawerItem> navDrawerItems;
public NavDrawerListAdapter(Context context, ArrayList<NavDrawerItem> navDrawerItems){
this.context = context;
this.navDrawerItems = navDrawerItems;
}
#Override
public int getCount() {
return navDrawerItems.size();
}
#Override
public Object getItem(int position) {
return navDrawerItems.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater)
context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.drawer_list_item, null);
}
// TODO: Here ViewHolder pattern can be used or
ImageView imgIcon = (ImageView) convertView.findViewById(R.id.icon);
TextView txtTitle = (TextView) convertView.findViewById(R.id.title);
// NOTE: check which item is Checked an set corresponding text color
if (((GridView)parent).isItemChecked(position)) {
txtTitle.setTextColor(context.getResources().getColor(R.color.red));
} else {
txtTitle.setTextColor(context.getResources().getColor(R.color.black));
}
imgIcon.setImageResource(navDrawerItems.get(position).getIcon());
txtTitle.setText(navDrawerItems.get(position).getTitle());
return convertView;
}
}
With above code, text color will be changed only after pointer up (when you press item it's color will still hold old value). If you need it to change color during pressed state, then use the following code in the adapter:
// NOTE: check which item is Checked an set corresponding text color
if (((GridView)parent).isItemChecked(position)) {
//txtTitle.setTextColor(context.getResources().getColor(R.color.red));
txtTitle.setTextColor(context.getResources().getColorStateList(R.color.red_selector));
} else {
//txtTitle.setTextColor(context.getResources().getColor(R.color.black));
txtTitle.setTextColor(context.getResources().getColorStateList(R.color.black_selector));
}
And provide color/red_selector.xml and color/black_selector.xml. E.g. color/black_selector.xml should look the following way:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="#color/red"/>
<item android:color="#color/black"/>
</selector>
