Launch Intent on click of ExpandableListView

Good evening everyone !
I am currently working on an ExpandableListView.
The parent contains 1 ImageView.
The child contains 1 TextView and 3 Buttons.
In terms of display, no problem: everything works as I want.
However, I want to add actions to my buttons and I realize that when I put a SetOnclickListener in the getChildView I am not able to launch a new INTENT.
The examples I find on the internet seem to show only clicks on dynamic elements. However, the buttons are not dynamic in my case.
I planned to use a variable to do a SWITCH and thus launch the right INTENT.
But since it doesn't work, I wonder if my direction is the right one.

Can somoene help me ?
I want to start a new intent on click on Button.
Edit : i add child Click Listener on MainActivity but its works only if i set clickable,focusable = false on the 3 Buttons in layout list_item.xml.
And than the click is on the complete child. I can't say if the click is on Button 1, 2 or 3.
Can we fix it ?

Problem solved.
I do this in ExpandableListAdapter in getChildView.
param.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent next = new Intent(parent.getContext(), parametres.class);
parent.getContext().startActivity(next);
}
});

How to open sub menu after click on menu-item in Navigation drawer?

I implemented a navigation drawer, with navigation view. and i am adding value in navigation view through a menu.xml file.
<android.support.design.widget.NavigationView
android:id="#+id/nvView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:itemTextColor="#android:color/white"
android:background="?attr/colorAccent"
app:menu="#menu/drawer_view"
app:headerLayout="#layout/nav_header"
>
</android.support.design.widget.NavigationView>
every thing is working fine, but i am facing a problem, I want to display submenu's , after click on menu.
I tried many thing's like:-
I add submenu in menu.xml, inside item.
somthing like this..
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item
android:id="#+id/nav_ChangeOutlet_fragment"
android:icon="#drawable/home_icon"
android:title="#string/changeOutlet"
android:checked="true">
<menu>
<group>
<item
android:title="one"></item>
<item
android:title="two"></item>
<item
android:title="three"></item>
</group>
</menu>
then it return me output like this.
Output: click on this link to see output
https://drive.google.com/file/d/0B0B9-WZYydK7RG1yY0tRdkhOSW8/view?usp=sharing
Now problem is that, in this way i am not able to click on menu , only sub menu are clickable here.
I want here to show sub menu , only after click on menu, otherwise sub menu does shown to other or say it is in invisible state

The best solution is to have an expandable list view in navigation view.See the code below
activity_navigation_view.xml
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawer_layout"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:fitsSystemWindows="true">
<include layout="#layout/navigation_view_fragment_container"/>
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_height="match_parent"
android:layout_width="wrap_content"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/navigation_view_header">
<ExpandableListView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#android:color/white"
android:layout_marginTop="192dp"
android:id="#+id/navigationmenu">
</ExpandableListView>
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
The layout navigation header is as below
navigation_view_header.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="192dp"
android:background="#ff5722"
android:padding="16dp"
android:theme="#style/ThemeOverlay.AppCompat.Dark"
android:orientation="vertical"
android:gravity="bottom">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Username"
android:textAppearance="#style/TextAppearance.AppCompat.Body1"/>
</LinearLayout>
In your navigation view activity, set the adapter for the expandable list view.
NavigationViewActivity.java
public class NavigationViewActivity extends AppCompatActivity {
private DrawerLayout mDrawerLayout;
ExpandableListAdapter mMenuAdapter;
ExpandableListView expandableList;
List<ExpandedMenuModel> listDataHeader;
HashMap<ExpandedMenuModel, List<String>> listDataChild;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_navigation_view);
final ActionBar ab = getSupportActionBar();
/* to set the menu icon image*/
ab.setHomeAsUpIndicator(R.drawable.ic_menu);
ab.setDisplayHomeAsUpEnabled(true);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
expandableList= (ExpandableListView) findViewById(R.id.navigationmenu);
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
if (navigationView != null) {
setupDrawerContent(navigationView);
}
prepareListData();
mMenuAdapter = new ExpandableListAdapter(this, listDataHeader, listDataChild, expandableList);
// setting list adapter
expandableList.setAdapter(mMenuAdapter);
}
private void prepareListData() {
listDataHeader = new ArrayList<String>();
listDataChild = new HashMap<String, List<String>>();
// Adding data header
listDataHeader.add("heading1");
listDataHeader.add("heading2");
listDataHeader.add("heading3");
// Adding child data
List<String> heading1= new ArrayList<String>();
heading1.add("Submenu of item 1");
List<String> heading2= new ArrayList<String>();
heading2.add("Submenu of item 2");
heading2.add("Submenu of item 2");
heading2.add("Submenu of item 2");
listDataChild.put(listDataHeader.get(0), heading1);// Header, Child data
listDataChild.put(listDataHeader.get(1), heading2);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
mDrawerLayout.openDrawer(GravityCompat.START);
return true;
}
return super.onOptionsItemSelected(item);
}
private void setupDrawerContent(NavigationView navigationView) {
navigationView.setNavigationItemSelectedListener(
new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
menuItem.setChecked(true);
mDrawerLayout.closeDrawers();
return true;
}
});
}
#Override
public void onFragmentInteraction(Boolean isDataSaved) {
}
}
The adapter for expandable list view is as follows
public class ExpandableListAdapter extends BaseExpandableListAdapter {
private Context mContext;
private List<String> mListDataHeader; // header titles
// child data in format of header title, child title
private HashMap<String, List<String>> mListDataChild;

}
TextView lblListHeader = (TextView) convertView

ImageView headerIcon= (ImageView)convertView.findViewById(R.id.iconimage);
lblListHeader.setTypeface(null, Typeface.BOLD);
lblListHeader.setText(headerTitle.getIconName());
headerIcon.setImageDrawable(headerTitle.getIconImg());
return convertView;
}
#Override

I have posted whole code for clarity. Hope this helps.......

You can create it using a ExpandableListview.
look at this

I prefer you should go with custom layout in side navigation drawer.
Here is sample link - how to implement custom layout in navigation drawer.
You also need to implement expandable listview in side navigation drawer for your scenario, here is sample of expandable list view.
You need to combine both things to achive navigation drawer with expandable list.

In the Navigation Drawer layout xml file. Above drawerView and inside your parent layout add an image view as shown below:
<ImageView
android:id="#+id/image"
android:layout_width="280dp"
android:layout_height="140dp"
android:src="respective_source_of_image" />
This should be sufficient. Hope this helps.
Use Recycler View to create a navigation drawer. Recycler view is used most now. In your navigation drawer fragment have your layout file as shown below. This make you achieve your objective:
<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"
tools:context="com.ms.t.tms.NavigationDrawerFragment">
<ImageView
android:id="#+id/image"
android:layout_width="280dp"
android:layout_height="140dp"
android:src="respective_image_src" />
<android.support.v7.widget.RecyclerView
android:id="#+id/drawerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/image"
android:background="#color/colorPrimary"></android.support.v7.widget.RecyclerView>
</RelativeLayout>

You can simply do it following this sample :
<?xml version="1.0" encoding="utf-8"?>
<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">
<!-- insert you main view childs here -->
</FrameLayout>
<!-- The navigation drawer -->
<LinearLayout
android:layout_width="240dp"
android:layout_gravity="end"
android:background="#color/colorPrimary"
android:orientation="vertical"
android:layout_height="match_parent">
<ImageView
android:layout_width="240dp"
android:layout_height="140dp"
android:src="#drawable/logo" />
<ListView
android:id="#+id/left_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="end"
android:choiceMode="singleChoice"
android:background="#color/colorPrimary"/>
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
You will have your image added before the listview. You can manage your view like any other view.
Hope it will help you ;)

but you do understand that ExpandableListView work like what I asked you..?
when you press on parent the parent expands (unless you state otherwise) and when you clikc on it again the parent collapses..
if you want to be able to expand the parent and also be able to check and uncheck the parent checkbox you need to give two views in the same row of the parent, the first is the checkbox and the second is the parent title (which can be empty like "")
they should be side by side.
you can do somthing like this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/Rl11"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:background="#drawable/desserts_main_expand"
android:orientation="horizontal" >
<ImageView
android:id="#+id/checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:clickable="true"
android:cropToPadding="true"
android:padding="4dp"
android:scaleType="fitXY"
android:src="#android:drawable/ic_menu_add" />
<TextView
android:id="#+id/ParentTextI"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_marginLeft="10dp"
android:layout_marginTop="10dp"
android:layout_toLeftOf="#+id/addIng"
android:layout_toRightOf="#+id/Side_image"
android:gravity="center_vertical"
android:scrollHorizontally="true"
android:text="dummy text"
android:textAlignment="center"
android:textColor="#color/white"
android:textSize="20sp"
android:textStyle="bold|italic" />
</RelativeLayout>
and then in the adapter:
declare a global variable
CheckBox checkbox;
**this is only for the parent checkbox part
public View getGroupView(int groupPosition, boolean isExpanded, View convertView,
ViewGroup parent) {
checkbox.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if(checkbox.isChecked()=true)
{checkbox.setChecked(false);}
else checkbox.setChecked(true);
ParentActivity.checkall();
}
});
and then in ParentActivity:
add a function that checks every child of the same parent:
public static void checkall()
{
for(int j=0 ; j<files.size() ; j++)
{if (listAdapter.checkbox.isChecked()==true)
{files.get(j).setChecked(true)};
}
I have made the code specially for you so there might be some error cause i havnt checked it..
but it supposed to be somthing like this.
