问题:
In google developer blog post . I read about new way to create navigation drawer using new dependency called
compile 'com.android.support:design:22.2.0'
but I didn’t found exact way to create navigation drawer using this new dependency.
In build.gradle , I have added dependency
compile 'com.android.support:design:22.2.0' compile 'com.android.support:appcompat-v7:22.0.0'
in layout file added following code (based on google blog post)
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true"> <!-- your content layout --> <android.support.design.widget.NavigationView 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>
Aslo I tried to extend class using ActionBarActivity but its deprecated?
Ref:http://android-developers.blogspot.in/2015/05/android-design-support-library.html
Any help appreciated .Thank you

Hi try following steps
Add Android design support library dependency
compile 'com.android.support:design:22.2.1'
Create a header for the navigation drawer
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="150dp" android:background="@drawable/header" android:padding="16dp" android:orientation="vertical" android:gravity="bottom"> <TextView android:textColor="#ffffff" android:textSize="18sp" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Nirav Kalola\nnkDroid" /> </LinearLayout>
Create a menu for navigation drawer items
<menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" tools:context="nkdroid.tutorial.navigationview.MainActivity"> <group android:checkableBehavior="single"> <item android:id="@+id/navigation_item_1" android:icon="@drawable/ic_action_home" android:title="Home"/> <item android:id="@+id/navigation_item_2" android:icon="@drawable/ic_action_info" android:title="About Us"/> <item android:id="@+id/navigation_subheader" android:title="Tutorials"> <menu> <item android:id="@+id/navigation_sub_item_1" android:icon="@drawable/ic_image_looks_one" android:title="Android Tutorials"/> <item android:id="@+id/navigation_sub_item_2" android:icon="@drawable/ic_image_looks_two" android:title="IOS Tutorials"/> </menu> </item> </group> </menu>
Create Navigation View with header and items
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/drawer_layout" android:fitsSystemWindows="true"> <!--Main content--> <LinearLayout android:orientation="vertical" android:id="@+id/main_content" android:layout_width="match_parent" android:layout_height="match_parent"> <include layout="@layout/app_bar"/> </LinearLayout> <!--Navigation Drawer--> <android.support.design.widget.NavigationView android:id="@+id/main_drawer" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_gravity="start" app:headerLayout="@layout/drawer_header" app:menu="@menu/menu_drawer"/> </android.support.v4.widget.DrawerLayout>

R.id.navigation_item_1: savedInstanceState.getInt("SELECTED_ID"); itemSelection(mSelectedId); } private void setToolbar() { toolbar= (Toolbar) findViewById(R.id.toolbar); if (toolbar != null) { setSupportActionBar(toolbar); } } private void initView() { mDrawer= (NavigationView) findViewById(R.id.main_drawer); mDrawer.setNavigationItemSelectedListener(this); mDrawerLayout= (DrawerLayout) findViewById(R.id.drawer_layout); } private void itemSelection(int mSelectedId) { switch(mSelectedId){ case R.id.navigation_item_1: mDrawerLayout.closeDrawer(GravityCompat.START); break; case R.id.navigation_item_2: mDrawerLayout.closeDrawer(GravityCompat.START); break; case R.id.navigation_sub_item_1: mDrawerLayout.closeDrawer(GravityCompat.START); break; case R.id.navigation_sub_item_2: mDrawerLayout.closeDrawer(GravityCompat.START); break; } } @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); drawerToggle.onConfigurationChanged(newConfig); } @Override public boolean onNavigationItemSelected(MenuItem menuItem) { menuItem.setChecked(true); mSelectedId=menuItem.getItemId(); itemSelection(mSelectedId); return true; } @Override public void onSaveInstanceState(Bundle outState, PersistableBundle outPersistentState) { super.onSaveInstanceState(outState, outPersistentState); //save selected item so it will remains same even after orientation change outState.putInt("SELECTED_ID",mSelectedId); } }

hello @user3739665 i am also trying to lean support library, but i don't think there is proper way(because no sample available right now). so here is my tried code, just for demonstration how to use that lib.
i change that layout to like below added main fragment, you can also add toolbar.
<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:fitsSystemWindows="true" android:layout_height="match_parent"> <!-- 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" />
i have create drawer.xml for menu and drawer_header.xml for user detail just like show in blog
my activity code
public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener { Toolbar toolbar; View root; NavigationView nav_draw; DrawerLayout drawer_layout; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //setContentView(R.layout.activity_main); root = getLayoutInflater().inflate(R.layout.activity_main, null); setContentView(root); toolbar = (Toolbar) findViewById(R.id.toolbar); setSupportActionBar(toolbar); final ActionBar ab = getSupportActionBar(); ab.setHomeAsUpIndicator(R.drawable.ic_menu); ab.setDisplayHomeAsUpEnabled(true); drawer_layout = (DrawerLayout)findViewById(R.id.drawer_layout); nav_draw = (NavigationView) findViewById(R.id.nav_draw); nav_draw.setNavigationItemSelectedListener(this); /* getSupportFragmentManager().beginTransaction() .replace(R.id.container, new AboutPagerFragment()) .commit();*/ } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case android.R.id.home: drawer_layout.openDrawer(GravityCompat.START); return true; } return super.onOptionsItemSelected(item); } @Override public boolean onNavigationItemSelected(MenuItem menuItem) { if (menuItem.getItemId() == R.id.navigation_item_1) { Snackbar .make(root, "First item Selected", Snackbar.LENGTH_LONG) //.setAction(R.string.snackbar_action, myOnClickListener) .show(); } menuItem.setChecked(true); drawer_layout.closeDrawers(); return false; } /*@Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.menu_main, menu); return true; }*/
}
add this in you build.gradle
dependencies { 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' }
drawer.xml
<?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:title="@string/navigation_item_1"> </item> <item android:id="@+id/navigation_item_2" android:title="@string/navigation_item_2" /> <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>
drawer_header.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:gravity="center" android:layout_height="130dip"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:textAppearance="?android:attr/textAppearanceMedium" android:text="Medium Text" android:id="@+id/textView" /> </LinearLayout>
EDIT
added navigation item open,close, enable items selection
回答3:
The "java part" can look like this:
Set your activity as a listener
navView.setNavigationItemSelectedListener(this);
And than handle events the same way you handle menu interaction
@Override public boolean onNavigationItemSelected(MenuItem menuItem) { int id = menuItem.getItemId(); menuItem.setChecked(true); drawerLayout.closeDrawers(); if (id == R.id.some_item_1) { } else if (id == R.id.some_item_2) { } else { throw new IllegalStateException("Unsupported menu item"); } return true; }
Check this github project for all examples of using design library.
回答4:
It's not clear exactly what your issue is (in what way did it not work?), but perhaps you missed the fact that you muse actually define the 'drawer_header' layout and the 'drawer' menu?
If that's not the problem, please explain in more detail exactly what you're having a problem with.
