Navigation drawer without action bar in android

Navigation drawer without action bar in android : 

The navigation drawer is a panel that displays the app’s main navigation options on the left edge of the screen. It is hidden most of the time, but is revealed when the user swipes a finger from the left edge of the screen or, while at the top level of the app, the user touches the app icon in the action bar.
This lesson describes how to implement a navigation drawer using the DrawerLayout APIs available in the Support Library.

Create a Drawer Layout

To add a navigation drawer, declare your user interface with aDrawerLayout object as the root view of your layout. Inside theDrawerLayout, add one view that contains the main content for the screen (your primary layout when the drawer is hidden) and another view that contains the contents of the navigation drawer.

<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"> <FrameLayout android:id="@+id/content_frame" android:layout_width="match_parent" android:layout_height="match_parent" /> <ListView android:id="@+id/left_drawer" android:layout_width="240dp" android:layout_height="match_parent" android:layout_gravity="start" android:choiceMode="singleChoice" android:divider="@android:color/transparent" android:dividerHeight="0dp" android:background="#111"/> </android.support.v4.widget.DrawerLayout>

This layout demonstrates some important layout characteristics:

• The main content view (the FrameLayout above) must be the first child in the DrawerLayout because the XML order implies z-ordering and the drawer must be on top of the content.
• The main content view is set to match the parent view's width and height, because it represents the entire UI when the navigation drawer is hidden.
• The drawer view (the ListView) must specify its horizontal gravity with the android:layout_gravityattribute. To support right-to-left (RTL) languages, specify the value with "start" instead of "left" (so the drawer appears on the right when the layout is RTL).
• The drawer view specifies its width in dp units and the height matches the parent view. The drawer width should be no more than 320dp so the user can always see a portion of the main content.

Hide the action bar

   hide the action bar while create the view using follow code.

this.requestWindowFeature(Window.FEATURE_NO_TITLE);

Initialize the Drawer List & Drawer Latyout

First,you have to initialize the drawer list and the drawer layout.Then have to set the values for the listview using adapter.

mColors = getResources().getStringArray(R.array.colors_array); mDrawerLayout=(DrawerLayout)findViewById(R.id.drawer_layout); mDrawerList=(ListView)findViewById(R.id.left_drawer);

Add Header view 

Inflate the layout into the new view called header.and set the header view into the listview.

header.xml

<?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="wrap_content" >     <RelativeLayout         android:id="@+id/RelativeLayout1"         android:layout_width="match_parent"         android:layout_height="80dp"         android:background="@drawable/bg" >         <TextView             android:id="@+id/textView1"             android:layout_width="match_parent"             android:layout_height="match_parent"             android:layout_alignParentTop="true"             android:layout_margin="5dp"             android:layout_toRightOf="@+id/profile_image"             android:gravity="center_vertical"             android:text="velmuruganandroidcoding.blogspot.in"             android:textAppearance="?android:attr/textAppearanceLarge"             android:textColor="@color/white"             android:textStyle="bold" />         <ImageView             android:id="@+id/profile_image"             android:layout_width="50dp"             android:layout_height="50dp"             android:layout_alignParentLeft="true"             android:layout_centerVertical="true"             android:background="@drawable/icon"             android:layout_margin="5dp"             android:gravity="center_vertical" />     </RelativeLayout> </FrameLayout>

View header=getLayoutInflater().inflate(R.layout.header, null); ImageView pro=(ImageView)header.findViewById(R.id.profile_image); pro.setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { // TODO Auto-generated method stub Toast.makeText(getApplicationContext(), "Clicked",                                                                                    Toast.LENGTH_SHORT).show(); } }); mDrawerList.addHeaderView(header);

Create Adapter for listview

create model class for get and set values.

private class ItemsModel{ private String itemName; private int itemImage; public ItemsModel(String name, int image) { // TODO Auto-generated constructor stub this.itemName=name; this.itemImage=image; } public String getItemName() { return itemName; } public void setItemName(String itemName) { this.itemName = itemName; } public int getItemImage() { return itemImage; } public void setItemImage(int itemImage) { this.itemImage = itemImage; } }

create adapter for listview

private class DrawerAdapter extends BaseAdapter{ ArrayList<ItemsModel> itemsmodel; public DrawerAdapter(ArrayList<ItemsModel> itemModel) { // TODO Auto-generated constructor stub this.itemsmodel=itemModel; } @Override public int getCount() { // TODO Auto-generated method stub return itemsmodel.size(); } @Override public Object getItem(int position) { // TODO Auto-generated method stub return itemsmodel.get(position); } @Override public long getItemId(int position) { // TODO Auto-generated method stub return position; } @Override public View getView(int position, View view, ViewGroup parent) { // TODO Auto-generated method stub if (view == null) {             LayoutInflater mInflater = (LayoutInflater)getSystemService(Activity.LAYOUT_INFLATER_SERVICE);             view = mInflater.inflate(R.layout.list_adapter, null);         } ImageView img=(ImageView)view.findViewById(R.id.img); TextView name=(TextView)view.findViewById(R.id.name); name.setText(itemsmodel.get(position).getItemName()); img.setImageResource(itemsmodel.get(position).getItemImage()); return view; } }

Add the names and images into the model and set the adapter in the listview.

itemModel.add(new ItemsModel("Black",itemImages.getResourceId(0, -1)));        itemModel.add(new ItemsModel("Red",itemImages.getResourceId(1, -1)));         itemModel.add(new ItemsModel("Green",itemImages.getResourceId(2, -1)));         itemModel.add(new ItemsModel("Blue",itemImages.getResourceId(3, -1)));         itemModel.add(new ItemsModel("pink",itemImages.getResourceId(4, -1)));         itemImages.recycle();         drawerAdapter=new DrawerAdapter(itemModel);         mDrawerList.setAdapter(drawerAdapter);

Handle Navigation Click Events

When the user selects an item in the drawer's list, the system calls onItemClick() on theOnItemClickListener given to setOnItemClickListener().

public class DrawerItemClickListener implements OnItemClickListener { @Override public void onItemClick(AdapterView<?> arg0, View view, int position, long arg3) { // TODO Auto-generated method stub if(position != 0){ lastIndex=position; selectItem(position); }else{ mDrawerList.setItemChecked(lastIndex, true); } } } private void selectItem(int position){ Log.d("POS", position+""); Fragment fragment=new ColorsFragment(); Bundle bundle=new Bundle(); bundle.putInt("Position", position-1); fragment.setArguments(bundle); FragmentManager fragmentManager=getFragmentManager();                  fragmentManager.beginTransaction().replace(R.id.content_frame,                       fragment).commit(); mDrawerList.setItemChecked(position, true); setTitle(mColors[position-1]); mDrawerLayout.closeDrawer(mDrawerList); }

in selectItem() you have to call the related fragment to the give position.Here I have create simple fragment and change the background color and text in depends on the give input.

public class ColorsFragment extends Fragment{ private int[] colors; private int position; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootview=inflater.inflate(R.layout.fragment_layout, container,false); position=getArguments().getInt("Position"); RelativeLayout layout=(RelativeLayout)rootview.findViewById(R.id.layout); TextView textView=(TextView)rootview.findViewById(R.id.textview); colors=getActivity().getResources().getIntArray(R.array.colors); textView.setText(getResources().getStringArray(R.array.colors_array)[position]); layout.setBackgroundColor(colors[position]); return rootview; } }
