Scrollview inside DrawerLayout prevents ListView buttons from working [duplicate]

I am trying to use the sliding navigation drawer in the app. However it seems that it's not handling the OnItemClick method. When I click on an item nothing happens.How can I make it work?Thanks
//MainActivity
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
drawer_layout = (DrawerLayout)findViewById(R.id.drawerLayout);
list_view = (ListView)findViewById(R.id.drawerList);
menu_items = getResources().getStringArray(R.array.nav_drawer_items);
list_view.setAdapter(new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, menu_items));
list_view.setOnItemClickListener(this);
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// TODO Auto-generated method stub
Toast.makeText(MainActivity.this, menu_items[position] + " was selected", Toast.LENGTH_LONG).show();
}

Your DrawerLayout's child Views are incorrectly z-ordered. The View for the drawer - in this case, the ListView - needs to be listed last in order to be on top of everything else.

Do it Simple like this: Add these line of code after setContentView(R.layout.activity_main); or what ever your activity name is.
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
// Initializing Drawer Layout and ActionBarToggle
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this,drawer,toolbar,R.string.navigation_drawer_open, R.string.navigation_drawer_close){
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
}
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
};
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
navigationView.bringToFront();
Then Move to next step:
#Override
public boolean onNavigationItemSelected(MenuItem item) {
displaySelectedScreen(item.getItemId());
return true;
}
private void displaySelectedScreen(int itemId){
try {
switch (itemId) {
case R.id.nav_menu1:
startActivity(new Intent(this, BActivity.class));
break;
case R.id.nav_menu2:
startActivity(new Intent(this, CActivity.class));
break;
}
}
catch (Exception e)
{
e.printStackTrace();
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer);
drawer.closeDrawer(GravityCompat.START);
}

For Left Menu Drawer Complete Simple you can try the following Simple....
MainActivity.class
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private String[] navMenuTitles;
private ArrayList<MainDrawerItem> navDrawerItems;

// for lefdrawer
mTitle = mDrawerTitle = getTitle();
// load slide menu items
navMenuTitles = getResources().getStringArray(
R.array.dashboard_leftMenu);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_dashboard_layout);
mDrawerList = (ListView) findViewById(R.id.main_dash_left_list_drawer);
navDrawerItems = new ArrayList<MainDrawerItem>();
navDrawerItems.add(new MainDrawerItem(navMenuTitles[0], 0,
null, false));
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,

// calling onPrepareOptionsMenu() to show action bar icons
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {

};
mDrawerLayout.setDrawerListener(mDrawerToggle);
if (savedInstanceState == null) {
// on first time display view for first nav item
displayView(0);
}
private void displayView(int position) {
// update the main content by replacing fragments

public class MainDrawerItem {

public MainDrawerItem(){

</RelativeLayout>

Ok, your problem will be solved here.
You should add these lines:
mDrawerList.bringToFront();
mDrawerLayout.requestLayout();
Also please note that SlideMenuClickListener should implement AdapterView.OnItemClickListener, not ListView.OnItemClickListener.
For future, please consider using NavigationView instead - it's also highly customizable and much easier, as for me.
Update. As you use support drawer, please try to
android.support.v4.app.Fragment;
android.support.v4.app.FragmentManager;
And use then getSupportFragmentManager().
I believe it should work.
Update2. Try to do like here:
remove ListView with #+id/list from main layout, leave there only frame_container and list_slidermenu.
Update3.
Make xml for fragment:
<?xml version="1.0" encoding="utf-8"?>
<ListView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent">
</ListView>
Make class for fragment:
public class NewFragment extends Fragment {
public NewFragment (){}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.new_fragment, container, false);
ListView list = (Listview) rootView.findViewById(R.id.list);
//then do what you need with this list
return rootView;
}
}
In MainActivity replace container with instance of your NewFragment.

activity_main.xml should be like this
Because of Framelayout tag is a container and must contain the json data listview
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

Your DrawerLayout's child Views are incorrectly z-ordered. The View for the drawer - in this case, the ListView - needs to be listed last in order to be on top of everything else.

Do it Simple like this: Add these line of code after setContentView(R.layout.activity_main); or what ever your activity name is.
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
// Initializing Drawer Layout and ActionBarToggle
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this,drawer,toolbar,R.string.navigation_drawer_open, R.string.navigation_drawer_close){
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
}
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
};
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
navigationView.bringToFront();
Then Move to next step:
#Override
public boolean onNavigationItemSelected(MenuItem item) {
displaySelectedScreen(item.getItemId());
return true;
}
private void displaySelectedScreen(int itemId){
try {
switch (itemId) {
case R.id.nav_menu1:
startActivity(new Intent(this, BActivity.class));
break;
case R.id.nav_menu2:
startActivity(new Intent(this, CActivity.class));
break;
}
}
catch (Exception e)
{
e.printStackTrace();
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer);
drawer.closeDrawer(GravityCompat.START);
}

For Left Menu Drawer Complete Simple you can try the following Simple....
MainActivity.class
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private String[] navMenuTitles;
private ArrayList<MainDrawerItem> navDrawerItems;
private NavDrawerListAdapter adapter;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// for lefdrawer
mTitle = mDrawerTitle = getTitle();
// load slide menu items
navMenuTitles = getResources().getStringArray(
R.array.dashboard_leftMenu);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_dashboard_layout);
mDrawerList = (ListView) findViewById(R.id.main_dash_left_list_drawer);
navDrawerItems = new ArrayList<MainDrawerItem>();
navDrawerItems.add(new MainDrawerItem(navMenuTitles[0], 0,
null, false));
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,
R.drawable.ic_drawer, // nav menu toggle icon
R.string.app_name, // nav drawer open - description for
// accessibility
R.string.app_name // nav drawer close - description for

) {
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);
}
private void displayView(int position) {
// update the main content by replacing fragments
switch (position) {
case 0:
Toast.makeText(MainActivity.this, ..... + " was selected",Toast.LENGTH_LONG).show();
break;
default:
break;
}
}
private class SlideMenuClickListener implements
ListView.OnItemClickListener {
#Override

// display view for selected nav drawer item
displayView(position);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {

return true;
}
// Handle action bar actions click
switch (item.getItemId()) {
case R.id.action_settings:
return true;
default:
return super.onOptionsItemSelected(item);
}
}
MainDrawerItem.class
public class MainDrawerItem {
private String title;
public MainDrawerItem(){
}
public MainDrawerItem(String title){
this.title = title;
}
public String getTitle(){
return this.title;
}
}
For Adapter Class
public class NavDrawerListAdapter extends BaseAdapter {
private Context context;
private ArrayList<MainDrawerItem> navDrawerItems;
public NavDrawerListAdapter(Context context, ArrayList<MainDrawerItem> navDrawerItems){
this.context = context;
this.navDrawerItems = navDrawerItems;
}
#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);
}
TextView txtTitle = (TextView) convertView.findViewById(R.id.title);
txtTitle.setText(navDrawerItems.get(position).getTitle());
return convertView;
}
}

Android Adapter getView

Sorry, this issue has been treated several times but I still can not solve it.
I have a Navigation Drawer with Fragment that works fine, but if I use it only with Activity I get error
You must supply a resource ID for a TextView.
This is my adapter, I do not think anything wrong. Thanks for the help
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);
}
ImageView imgIcon = (ImageView) convertView.findViewById(R.id.icon);
TextView txtTitle = (TextView) convertView.findViewById(R.id.text1);
imgIcon.setImageResource(navDrawerItems.get(position).getIcon());
txtTitle.setText(navDrawerItems.get(position).getTitle());
return convertView;
}
}

just create a holder class and use textview inside the getview() like this.
holder.textview = (TextView) convertView.findViewById(R.id.text1);
and below class for Holder class.
public class Holder {
TextView textview;
//CheckBox check;
}

How to Add icons adjacent to titles for Android Navigation Drawer

I am currently working on an android app for 4.2.2 that uses the new NavigationDrawer. It works like a charm except for adding icons.
I found some sample code in which the List view becomes a Relative layout in which 2 parallel arrays are nested and rendered by an Array Adapter based on a menu model a way that they are synchronized, I think.
Here is the MainActivity:

How can I simplify the approach. Is there a way to use one array instead of such a complicated structure.
B.t.w. you can find my project on github under:
https://github.com/greenspand/MediSynced
It is a medical app, hence the name.
Thx y'all.

You can use a custom list view along with the list adapter to display the counter besides the list item in the drawer. And then add whatever code you want to your counter method.
Here's the code I implemented in my navigation drawer supported android app :
getter/setter methods class for the drawer :
package info.aea.drawer;
public class NavDrawerItem {
private String title;
private String tag;
private int icon;
private String count = "0";
// boolean to set visibility of the counter
private boolean isCounterVisible = false;
public NavDrawerItem(){}
public NavDrawerItem(String title, String tag, int icon){
this.title = title;
this.tag = tag;
this.icon = icon;
}
public NavDrawerItem(String title, String tag, int icon, boolean isCounterVisible, String count){
this.title = title;
this.tag = tag;
this.icon = icon;
this.isCounterVisible = isCounterVisible;
this.count = count;
}
public String getTitle(){
return this.title;
}
public String getTag(){
return this.tag;
}
public int getIcon(){
return this.icon;
}
public String getCount(){
return this.count;
}
public boolean getCounterVisibility(){
return this.isCounterVisible;
}
public void setTitle(String title){
this.title = title;
}
public void setTag(String tag){
this.tag = tag;
}
public void setIcon(int icon){
this.icon = icon;
}
public void setCount(String count){
this.count = count;
}
public void setCounterVisibility(boolean isCounterVisible){
this.isCounterVisible = isCounterVisible;
}
}
This is the list adapter I used to display the list. check the display count method in the end :
package info.aea.drawer;
import info.aea.snippets.R;
import java.util.ArrayList;
import android.app.Activity;
import android.content.Context;

here's my layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<ImageView
android:id="#+id/drawer_item_icon"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginLeft="10sp"
android:layout_marginRight="10sp"
android:src="#drawable/ic_launcher" />
<TextView
android:id="#+id/drawer_item_text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="25sp"
android:paddingTop="8sp"
android:paddingBottom="8sp"
android:paddingLeft="15sp" />
</LinearLayout>

Simplest way I did it is this way:
1. Make this as your drawer xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tashan="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:orientation="horizontal"
android:padding="#dimen/spacing_small" >
<ImageView
android:id="#+id/drawer_item_icons"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginLeft="#dimen/spacing_small"
android:layout_marginStart="#dimen/spacing_small"
android:contentDescription="#string/test_string"/>
<TextView
android:id="#+id/drawer_item_labels"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginLeft="#dimen/spacing_normal"
android:layout_marginStart="#dimen/spacing_small"
android:paddingLeft="#dimen/spacing_small"
android:paddingRight="#dimen/spacing_small"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textColor="#58585b" />
</LinearLayout>
2. Add these values to your 'dimens.xml'. Never hardcode values!
<dimen name="spacing_normal">16dp</dimen>
<dimen name="spacing_small">8dp</dimen>
3. For Icons array add this String Array to 'strings.xml
<string-array name="array_main_menu">
<item>#drawable/1</item>
<item>#drawable/2</item>
<item>#drawable/3</item>
<item>#drawable/4</item>
<item>#drawable/5</item>
</string-array>
4. In your Adapter access this array by using a Typed Array instance.
TypedArray typedArray=getResources().obtainTypedArray(R.array.array_main_menu);
5. Inside the getView of your adapter, set image to Imageview like this.
mIcon.setImageResource(typedArray.getResourceId(position, -1));
here mIcon is your ImageView.

With recent versions of Support Library, the easiest way is to use a NavigationView. Here is a nice tutorial, and here is the official documentation.
A NavigationView is included as second view in the DrawerLayout (instead of ListView from OP code), for example:
<android.support.design.widget.NavigationView
android:id="#+id/navigation"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:menu="#menu/left_menu" />
Then, the menu should be populated with titles and icons, like (left_menu.xml):
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group
android:id="#+id/leftMenuId"
android:checkableBehavior="single">
<item
android:id="#+id/item1"
android:icon="#drawable/ic_zzblack_24dp"
android:title="Title1" />
<item
android:id="#+id/settings"
android:icon="#drawable/ic_settings_black_24dp"
android:title="Settings" />
</group>
</menu>
