I want to create a NavigationView with checkbox or switch , I just want to have this feature in my navigation to items switch and it should work just like this : When I turn one switch to another it changes to off state. What I did to have a switch is, this :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.SwitchCompat
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:id="#+id/switchs"
/>
</LinearLayout>
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<group android:checkableBehavior="single">
<item
android:id="#+id/nav_menu1"
android:icon="#mipmap/ic_launcher"
android:title="Menu 1" />
<item
android:id="#+id/nav_menu2"
android:icon="#mipmap/ic_launcher"
android:title="Menu 2" />
<item
android:id="#+id/nav_menu3"
app:actionLayout="#layout/action_view_switch"
android:icon="#mipmap/ic_launcher"
android:title="Menu 3" />
<item
android:id="#+id/nav_menu4"
app:actionLayout="#layout/action_view_switch"
android:icon="#mipmap/ic_launcher"
android:title="Menu 4" />
</group>
</menu>
But I can not have a value or status a switch and have a listener to see a change status
first of all create a layout action_view_checkbox.xml as below
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<TextView
android:layout_centerVertical="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="#+id/checkbox" />
<android.support.v7.widget.AppCompatCheckBox
android:id="#+id/checkbox"
android:layout_centerVertical="true"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignParentRight="true"
android:text="" />
</RelativeLayout>
and add layout as an item to the menu
<menu xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/check_box_menu"
app:actionLayout="#layout/action_view_checkbox"
android:title="Title" />
</menu>
And check click event as
Menu menu = navigationView.getMenu();
MenuItem menuItem = menu.findItem(R.id.check_box_menu);
View actionView = MenuItemCompat.getActionView(menuItem);
actionView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});

Please, I integrated the new Navigation Controller Component, using navHostFragment. My project runs on one activity-to-many fragments. It got a drawer & toolbar. I read that it is possible to set the ids in both menus (drawer, toolbar), to same ids in nav_graph for navigation when onClick event occurs.

Everything works as per navigation if I use the below:
subText.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// action_global_aboutFragment
NavController navController = Navigation.findNavController(v);
navController.navigate(R.id.nested_settings);
}
});
More Info:
minSdkVersion 23
targetSdkVersion 30
Implementation:
// Java language implementation
def nav_version = "2.3.3"
implementation "androidx.navigation:navigation-fragment:$nav_version"
implementation "androidx.navigation:navigation-ui:$nav_version"
I need a solution to this, as regards IDs to IDs linking. I love the concept. Who got this working on Android Java?
Solved!
Listeners are needed for both Drawer & Toolbar
// setup click listeners for Drawer & Toolbar
drawerView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
int id = menuItem.getItemId();
if(id == R.id.accountFragment) {
// add your code here
} else {
NavigationUI.onNavDestinationSelected(menuItem, navController);
}
drawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
// drawerLayout.closeDrawer(GravityCompat.START);
return true;
}
});
toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
// Handle Menu item selection
switch (item.getItemId()) {
case R.id.aboutFragment:
// add your code here
return true;
default:
// default function;
NavigationUI.onNavDestinationSelected(item, navController);
return true;
}
// return false;
}
});
Thank you.
I want create following customized bottom navigation bar. How I can set custom layout for menu item? or is there exists ready library for creating this type bottom bar easily?
My code below work fine:
First, you need create a Bottom Navigation Activity template project in Android Studio and apply my code below:
button_custom.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageButton
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_gravity="center"
android:background="#drawable/button_border"
android:src="#drawable/ic_baseline_add_24"/>
</FrameLayout>
button_border.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="8dp"/>
<solid android:color="#android:color/holo_blue_light"/>
</shape>
ic_baseline_add_24.xml
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="24dp"
android:height="24dp"
android:tint="#android:color/white"
android:viewportWidth="24"
android:viewportHeight="24">
<path
android:fillColor="#android:color/white"
android:pathData="M19,13h-6v6h-2v-6H5v-2h6V5h2v6h6v2z" />
</vector>
bottom_nav_menu.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/navigation_home"
android:icon="#drawable/ic_home_black_24dp"
android:title="#string/title_home" />
<item
android:id="#+id/navigation_dashboard"
android:title="" />

android:title="#string/title_notifications" />
</menu>

</androidx.constraintlayout.widget.ConstraintLayout>
MainActivity.kt
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val navView: BottomNavigationView = findViewById(R.id.nav_view)
val navController = findNavController(R.id.nav_host_fragment)
// Passing each menu ID as a set of Ids because each
// menu should be considered as top level destinations.
val appBarConfiguration = AppBarConfiguration(setOf(
R.id.navigation_home, R.id.navigation_dashboard, R.id.navigation_notifications))
setupActionBarWithNavController(navController, appBarConfiguration)
navView.setupWithNavController(navController)
//Add custom tab menu
val bottomMenuView = navView.getChildAt(0) as BottomNavigationMenuView
val view = bottomMenuView.getChildAt(1)
val itemView = view as BottomNavigationItemView
val viewCustom = LayoutInflater.from(this).inflate(R.layout.button_custom, bottomMenuView, false)
itemView.addView(viewCustom)
}
}
My result:
This is just themed and the icon is set with: <item android:icon="#drawable/some_icon" ... />.
Requesting a library for such a simple task is a) questionable and b) also considered as off-topic.
The Toolbar shows only the Title from the Item in menu_main for toolbar
My MainActivity Toolbar
<androidx.appcompat.widget.Toolbar

Correctly shown in Android Studio:
What's wrong in that situation?
Incorrectly displayed only on the device, namely, only the title property of the item itself is displayed
I just changing this:
android:actionLayout="#layout/coin_bar"
to this:
app:actionLayout="#layout/coin_bar"

I have tried something for you, hope it will solve your problem and you can customize xmls i.e background of custom_item.xml TextView according to your need.
activity_main.xml

</shape>
rest your MainActivity (java) code is same, there is no need to set a style to your list item text view.
Here is the screen shot of the output.
You can remove styles.
Only you should add android:padding="7dp" to parent LinearLayout and android:background="#drawable/simple_auto" to TextView in custom_item. It is working.
custom_item:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:tools="http://schemas.android.com/tools"
android:padding="7dp"
android:background="#color/cardview_color">
<TextView
android:id="#+id/autoCompleteItem"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/simple_auto"
android:padding="10dp"
android:textSize="15sp"/>
</LinearLayout>
I am having a problem in trying to set up a Navigaion Drawer for a Android App. Here is the for the tutorial I was following. http://www.recursiverobot.com/post/59404388046/implementing-the-new-navigation-drawer-in-android
This is the error that I get when I try to run the code:
Attempt to invoke virtual method 'void android.support.v7.app.ActionBar.setDisplayHomeAsUpEnabled(boolean)' on a null object reference
I believe my problem is somewhere in my xml code. Here is my onCreate() method MainActivity.java:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.content_main);
mTitle = "test";
mPlanetTitles = new String[]{"Home", "Settings", "Application", "Contact Us"};
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
mDrawerList.setAdapter(new ArrayAdapter<String>(this, R.layout.drawer_list_item, mPlanetTitles));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
ActionBar myBar = getSupportActionBar();

I apologize for the excessive question but I was no sure with how much information would be needed. I have tried putting the code that is currently in the content_main.xml in the acivity_main.xml, tried using just getActionBar(). I believe the issue might be somewhere in my ActionBarDrawerToggle declaration. Any help would be appreciated.
