this is my adapter
#Override
public View getView(final 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);

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());
ch.setSelected(navDrawerItems.get(position).getCounterVisibility());
ch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
boolean ans = ch.isChecked();
navDrawerItems.get(position).setCounterVisibility(ans);
Toast.makeText(context,String.valueOf(ch.isChecked()),Toast.LENGTH_LONG).show();
}
});
// 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();
}
});

Hide a Navigation Drawer Menu Item - Android

I have a navigation drawer. When an event is called, I want to hide one of my navigation menu item for user. How can I do that?

}

I want to hide my navigation drawer menu item at index 2. How to do that?
UPDATE
I have 5 menu items in my navigation drawer, I want to hide one of them when some event is called.

NavigationView navigationView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
hideItem();
}
private void hideItem()
{
navigationView = (NavigationView) findViewById(R.id.nav_view);
Menu nav_Menu = navigationView.getMenu();
nav_Menu.findItem(R.id.nav_settings).setVisible(false);
}

This will work as setInvisibility(GONE):
Menu nav_Menu = navigationView.getMenu();
nav_Menu.findItem(R.id.nav_profile).setVisible(false);
nav_Menu.findItem(R.id.menu_login).setVisible(true);
nav_Menu.findItem(R.id.menu_logout).setVisible(false);
nav_Menu.findItem(R.id.menu_regsitration).setVisible(true);

Kotlin version
val navigationView: NavigationView = findViewById(R.id.nav_view)
val navMenu: Menu = navigationView.menu
navMenu.findItem(R.id.nav_remove_ads).isVisible = true

You can delete the second item of listview via following code:
navDrawerItems.remove(2);
((BaseAdapter)adapter).notifyDataSetChanged();

NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
Menu menu =navigationView.getMenu();
MenuItem target = menu.findItem(R.id.nav_target);
target.setVisible(false);

Hide/Show Navigation item
Make changes in your NavDrawerListAdapter as follow,
public class MyListAdapter extends BaseAdapter {
Context context;
ArrayList<ItemListModel> listMenuItem;
ArrayList<ItemListModel> listMenuItem1;
int hideViewIndex = -1;
public MyListAdapter(Context context, ArrayList<ItemListModel> listMenuItem) {
this.context = context;
this.listMenuItem = listMenuItem;
listMenuItem1=new ArrayList<ItemListModel>(listMenuItem);
}
#Override
public int getCount() {
return listMenuItem.size();
}
#Override
public Object getItem(int position) {
return listMenuItem.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
private class ViewHolder
{
private ImageView imgLogo;
private TextView txtItemName;
}
public void hideView(int pos)
{
listMenuItem.remove(pos);
notifyDataSetChanged();
}
public void showView(int pos)
{
listMenuItem.add(pos, listMenuItem1.get(pos));
notifyDataSetChanged();
}
#SuppressLint("InflateParams")
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder = null;
if(convertView == null)
{
LayoutInflater myLayoutInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = myLayoutInflater.inflate(R.layout.activity_item_list, null);
viewHolder = new ViewHolder();
viewHolder.imgLogo = (ImageView) convertView.findViewById(R.id.imgLogo);
viewHolder.txtItemName = (TextView) convertView.findViewById(R.id.txtItemName);
convertView.setTag(viewHolder);
}
else
{
viewHolder = (ViewHolder) convertView.getTag();
}
ItemListModel itemListModel = listMenuItem.get(position);
viewHolder.imgLogo.setImageDrawable(itemListModel.getImageLogo());
viewHolder.txtItemName.setText(itemListModel.getStrItemName());
return convertView;
}
and call this method in activity as follow,
adapter.hideView(2);
//adapter.showView(2);

//hide logout menu item when the user is not loggrd in
//Checking the condition whether the user is logged in or not
if (!SharedPrefManager.getmInstance(this).isLoggedIn()){
Menu nav_Menu = navigationView.getMenu();
nav_Menu.findItem(R.id.nav_logout).setVisible(false);
}
//SharedPrefManager .java class where we define the isLoggedIn Method()
import android.content.Context;
import android.content.SharedPreferences;
import com.motortrade.motortrade.t_Model.User;
public class SharedPrefManager {
private static final String SHARED_PREF_NAME = "my_shared_pref";
private static SharedPrefManager mInstance;
private Context mCtx;
private SharedPrefManager(Context mCtx){
this.mCtx = mCtx;
}
public static synchronized SharedPrefManager getmInstance(Context mCtx){
if (mInstance == null){
mInstance = new SharedPrefManager(mCtx);
}
return mInstance;
}
public boolean isLoggedIn(){
SharedPreferences preferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE);
return preferences.getInt("user_id", -1) != -1;
}

navigationView = findViewById(R.id.nav_view);
navigationView.getMenu().findItem(R.id.nav_profile).setVisible(false);

NavigationView navigationView;
mapIntentActivity = getIntent();
navItemString = mapIntentActivity.getStringExtra("success");
if(navItemString != null) {
navigationView = (NavigationView) findViewById(R.id.nav_view);
Menu nav_Menu = navigationView.getMenu();
nav_Menu.findItem(R.id.nav_car).setVisible(false);
}

If we need to hide the menu item permanently (not temporary and programmatically), we can hide it in the XML view, in the menu.xml file by adding line android:visible="false":
<item
android:id="#+id/action_create"
android:title="#string/menu_action_create"
android:visible="false" />

Making first list item bigger than remaining items in Navigation Bar

I am having a navigation drawer working fine and it get displayed like this :
Now I want A profile picture of person at top like in google plus :
I had taken the help from http://www.androidhive.info/2013/11/android-sliding-menu-using-navigation-drawer/
But am not able to understand how to modify the xml such that I can make the uppermost list item with more height than remaining items of the list.

Seeing the comment here is getView method .Now what should i do next ?
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);
}
ImageView imgIcon = (ImageView) convertView.findViewById(R.id.icon);
TextView txtTitle = (TextView) convertView.findViewById(R.id.title);
TextView txtCount = (TextView) convertView.findViewById(R.id.counter);
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()){
txtCount.setText(navDrawerItems.get(position).getCount());
}else{
// hide the counter view
txtCount.setVisibility(View.GONE);
}
return convertView;
}
xml for header :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="100dp"
android:background="#drawable/list_selector">
<ImageView
android:id="#+id/icon"
android:layout_width="25dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginLeft="12dp"
android:layout_marginRight="12dp"
android:contentDescription="#string/desc_list_item_icon"
android:src="#drawable/ic_home"
android:layout_centerVertical="true" />
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_toRightOf="#id/icon"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:textColor="#color/list_item_title"
android:gravity="center_vertical"
android:paddingRight="40dp"/>
</RelativeLayout>

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

(FRAGMENT) UPDATE LISTVIEW WHEN I CLICK FRAGMENT MENU

if i delete item/s on listview and then i click the home menu in navigation drawer the listview won't update.

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

Drawer items Selected effect in android

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>
