Android Material Design (with Design support Library) - 4




Introducing Design Support Library , to use Material design component in older version API - android 2.1 and above. You’ll find a navigation drawer view, floating labels for editing text, a floating action button, snackbar, tabs, and a motion and scroll framework to tie them together.

I have used my previous example, so its easy for demonstrate. 

Note:

  • Update your Android SDK support repositories, support library if not updated
  • used compileSdkVersion 'android-MNC' for Android M but you can change it to build in older API
add dependencies in build.gradle file
compile 'com.android.support:appcompat-v7:22.2.0'
compile 'com.android.support:design:22.2.0'
compile 'com.android.support:support-v4:22.2.0'

start with navigation drawer, its very easy to use

lets, design for drawer

 <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_width="match_parent"  
   android:layout_height="match_parent"  
   android:fitsSystemWindows="true">  
   <!-- your content layout -->  
   <!--<FrameLayout  
     android:id="@+id/container"  
     android:layout_width="match_parent"  
     android:layout_height="match_parent" />-->  
   <include layout="@layout/about_fragment"></include>  
   <android.support.design.widget.NavigationView  
     android:id="@+id/nav_draw"  
     android:layout_width="wrap_content"  
     android:layout_height="match_parent"  
     android:layout_gravity="start"  
     app:headerLayout="@layout/drawer_header"  
     app:menu="@menu/drawer" />  
 </android.support.v4.widget.DrawerLayout>  

drawer menus will be a collection of checkable menu items


 <?xml version="1.0" encoding="utf-8"?>  
 <menu xmlns:android="http://schemas.android.com/apk/res/android">  
   <group android:checkableBehavior="single">  
     <item  
       android:id="@+id/navigation_item_1"  
       android:checked="true"  
       android:icon="@drawable/ic_drawer_map"  
       android:title="@string/title_section1">  
     </item>  
     <item  
       android:id="@+id/navigation_item_2"  
       android:icon="@drawable/ic_drawer_people_met"  
       android:title="@string/title_section2" />  
     <item  
       android:id="@+id/navigation_item_3"  
       android:icon="@drawable/ic_drawer_experts"  
       android:title="@string/title_section3" />  
     <item  
       android:id="@+id/navigation_item_4"  
       android:icon="@drawable/ic_drawer_explore"  
       android:title="@string/title_section4" />  
     <item  
       android:id="@+id/navigation_item_5"  
       android:icon="@drawable/ic_drawer_social"  
       android:title="@string/title_section5" />  
     <item  
       android:id="@+id/navigation_item_6"  
       android:icon="@drawable/ic_drawer_social"  
       android:title="@string/title_section6" />  
     <item  
       android:id="@+id/navigation_subheader"  
       android:title="@string/navigation_subheader">  
       <menu>  
         <item  
           android:id="@+id/navigation_sub_item_1"  
           android:title="@string/navigation_sub_item_1" />  
         <item  
           android:id="@+id/navigation_sub_item_2"  
           android:title="@string/navigation_sub_item_2" />  
       </menu>  
     </item>  
   </group>  
 </menu>  

use navigation item Listener


 public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener  

add override method


 @Override  
   public boolean onNavigationItemSelected(MenuItem menuItem) {  
     return false;  
   }  

in onCreate,


 NavigationView nav_draw = (NavigationView) findViewById(R.id.nav_draw);  
 nav_draw.setNavigationItemSelectedListener(this);  

Add Action, on Navigation Item select change onNavigationItemSelected method,


 @Override  
   public boolean onNavigationItemSelected(MenuItem menuItem) {  
     if (menuItem.getItemId() == R.id.navigation_item_1) {  
       Snackbar  
           .make(fab, "First item Selected", Snackbar.LENGTH_LONG)  
               //.setAction(R.string.snackbar_action, myOnClickListener)  
           .show();  
     } else if (menuItem.getItemId() == R.id.navigation_item_2) {  
       //startActivity(new Intent(MainActivity.this, DetailActivity.class));  
       if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {  
         getWindow().setExitTransition(new Explode());  
         Intent intent = new Intent(this, DetailActivity.class);  
         startActivity(intent,  
             ActivityOptionsCompat  
                 .makeSceneTransitionAnimation(this).toBundle());  
       } else {  
         startActivity(new Intent(MainActivity.this, DetailActivity.class));  
       }  
     } else if (menuItem.getItemId() == R.id.navigation_item_3) {  
       String url = "http://www.dj-android.blogspot.com";  
       Intent i = new Intent(Intent.ACTION_VIEW);  
       i.setData(Uri.parse(url));  
       startActivity(i);  
     } else if (menuItem.getItemId() == R.id.navigation_item_4) {  
       /*Snackbar  
           .make(root, "", Snackbar.LENGTH_LONG)  
               //.setAction(R.string.snackbar_action, myOnClickListener)  
           .setActionTextColor(getResources().getColor(R.color.colorRed))  
           .show();*/  
     }  
     menuItem.setChecked(true);  
     drawer_layout.closeDrawers();  
     return false;  
   }  

all this about navigation drawer view, no need to add extra fragment for drawer,

Floating Action Button



The Design library’s FloatingActionButton gives you a single consistent implementation, by default colored using the colorAccent from your theme.

 <android.support.design.widget.FloatingActionButton  
     android:layout_width="wrap_content"  
     android:layout_height="wrap_content"  
     android:layout_margin="16dp"  
     android:clickable="true"  
     android:id="@+id/fab_action"  
     android:src="@drawable/ic_discuss"  
     app:layout_anchor="@id/appbar"  
     app:layout_anchorGravity="bottom|right|end" />  


Collapsing Toolbars




Adding a Toolbar directly to an AppBarLayout gives you access to the enterAlwaysCollapsed and exitUntilCollapsed scroll flags, but not the detailed control on how different elements react to collapsing. For that, you can use CollapsingToolbarLayout.


 <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"  
   xmlns:app="http://schemas.android.com/apk/res-auto"  
   android:id="@+id/main_content"  
   android:layout_width="match_parent"  
   android:layout_height="match_parent"  
   android:fitsSystemWindows="true">  
   <android.support.design.widget.AppBarLayout  
     android:id="@+id/appbar"  
     android:layout_width="match_parent"  
     android:layout_height="200dip"  
     android:fitsSystemWindows="true"  
     android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">  
     <android.support.design.widget.CollapsingToolbarLayout  
       android:id="@+id/collapsing_toolbar"  
       android:layout_width="match_parent"  
       android:layout_height="match_parent"  
       android:fitsSystemWindows="true"  
       app:contentScrim="?attr/colorPrimary"  
       app:expandedTitleMarginEnd="64dp"  
       app:expandedTitleMarginStart="48dp"  
       app:layout_scrollFlags="scroll|exitUntilCollapsed">  
       <ImageView  
         android:id="@+id/backdrop"  
         android:layout_width="match_parent"  
         android:layout_height="match_parent"  
         android:fitsSystemWindows="true"  
         android:scaleType="centerCrop"  
         android:src="@drawable/my_pic"  
         app:layout_collapseMode="parallax" />  
       <android.support.v7.widget.Toolbar  
         android:id="@+id/toolbar"  
         android:layout_width="match_parent"  
         android:layout_height="?attr/actionBarSize"  
         app:layout_collapseMode="pin"  
         app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />  
     </android.support.design.widget.CollapsingToolbarLayout>  
   </android.support.design.widget.AppBarLayout>  
   <android.support.v4.widget.NestedScrollView  
     android:layout_width="match_parent"  
     android:layout_height="match_parent"  
     android:padding="10dip"  
     app:layout_behavior="@string/appbar_scrolling_view_behavior">  
     <TextView  
       android:id="@+id/textView"  
       android:padding="10dip"  
       android:layout_width="wrap_content"  
       android:layout_height="wrap_content"  
       android:elevation="5dp"  
       android:textColor="@color/textColorPrimary"  
       android:background="@drawable/myrect"  
       android:text="@string/intro"  
       android:textAppearance="?android:attr/textAppearanceMedium" />  
   </android.support.v4.widget.NestedScrollView>  
   <android.support.design.widget.FloatingActionButton  
     android:layout_width="wrap_content"  
     android:layout_height="wrap_content"  
     android:layout_margin="16dp"  
     android:clickable="true"  
     android:id="@+id/fab_action"  
     android:src="@drawable/ic_discuss"  
     app:layout_anchor="@id/appbar"  
     app:layout_anchorGravity="bottom|right|end" />  
 </android.support.design.widget.CoordinatorLayout>

Why Domain-Specific AI Agents Beat One Big Agent

Everyone is building agents right now. Real estate firms. Independent insurance brokers. Fortune 500 companies with budgets big enough to hire an army of consultants. Ask around and you'll hear the same story everywhere: "we're building our own agent." And yet almost nobody is asking the obvious question: why does the default approach keep failing? One large, general-purpose agent gets wired up to every tool the business owns. It impresses in the demo. Then it quietly stalls before production. There's a gap between what businesses want and what they're actually getting. They want AI woven into their data, their workflows, their day-to-day operations. What they get instead is one oversized agent trying to be a sales rep, a compliance officer, and a customer support line, all at once. That gap is an architecture problem, not a model problem. Key Takeaways The default "one big agent" pattern breaks down on context bloat, cost, fragility, and portability...

Don't Ship AI Agent Skills Without Evals

At the AI Engineer World's Fair on July 1, 2026, Philipp Schmid, a Staff Engineer on the Gemini API and agents team at Google DeepMind, asked a room full of engineers a simple question: who uses skills with their coding agents? Every hand went up. Who has evals for those skills? Almost none. That gap is the entire talk, which Schmid also wrote up on his own blog, philschmid.de/testing-skills . His team indexed the skills ecosystem through SkillsBench and found the same pattern everywhere: people ship a SKILL.md file after two manual test runs and move on. It looks fine in a demo. It quietly corrupts outputs in production, because bad skills don't crash. They just make the agent confidently wrong. If you've already read our breakdown of Matt Pocock's Claude Code skills library , think of this as the other half of that story: what happens once you've installed a skill and it's actually running against real prompts. Key Takeaways SkillsBench indexed 47,000+ un...
