Hi Guys, Maybe you all are expert in terms of using RecyclerView in android. This blog is simple example for using filter option with RecyclerView adapter. As for now you will instantiate RecyclerView and set the adapter to RecyclerView as following way. RecyclerView list = (RecyclerView) findViewById(R.id.list); list.setLayoutManager(new LinearLayoutManager(this)); list.setHasFixedSize(true); ArrayList<Number> numbers = new ArrayList<>(); String ONEs[] = {"ZERO", "ONE", "TWO", "THREE", "FOUR", "FIVE", "SIX", "SEVEN", "EIGHT", "NINE", "TEN"}; String TENs[] = {"ZERO", "TEN", "TWENTY", "THIRTY", "FOURTY", "FIFTY", "SIXTY", "SEVENTY", "EIGHTY", "NINETY", "HUNDRED"}; String HUNDREDS[] = {"ZERO", "HUNDRED", "TWO HUND
Consider using simple NavigationView instead of this old Navigation drawer, which based on Material design and much simpler and very flexible than this Navigation drawer.
This NavigationDrawer example is developed by using appcompat library project in eclipse kepler.
Code:
MainActivity.java
Code:
NavigationDrawerFragment.java
Code:
MyDrawerAdapter.java
Code:
HomeFragment.java
Code:
MailFragment.java
And your
activity_main.xml
And your
fragment_navigation_drawer.xml
And your
drawer_list.xml
And your
fragment_home.xml
And your
fragment_mail.xml
And your
fragment_settings.xml
And your
res/menu/global.xml
And your
res/menu/menu.xml
Create a xml called
res/values/myactionbar.xml
And your
res/drawable/actionbar_background.xml

Code:
MyDrawerAdapter.java
import android.content.Context; import android.graphics.Color; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.ImageView; import android.widget.TextView; public class MyDrawerAdapter extends BaseAdapter { private Context context; private String[] titles; private int[] images; private LayoutInflater inflater; private int[] selectedposition; public MyDrawerAdapter(Context context, String[] titles, int[] images, int[] selectedposition) { // TODO Auto-generated constructor stub this.context = context; this.titles = titles; this.images = images; this.inflater = LayoutInflater.from(this.context); this.selectedposition = selectedposition; } @Override public int getCount() { // TODO Auto-generated method stub return titles.length; } @Override public Object getItem(int position) { // TODO Auto-generated method stub return null; } @Override public long getItemId(int position) { // TODO Auto-generated method stub return 0; } @Override public View getView(int position, View convertView, ViewGroup parent) { // TODO Auto-generated method stub ViewHolder mViewHolder; if (convertView == null) { convertView = inflater.inflate(R.layout.drawer_list, null); mViewHolder = new ViewHolder(); convertView.setTag(mViewHolder); } else { mViewHolder = (ViewHolder) convertView.getTag(); } mViewHolder.tvTitle = (TextView) convertView .findViewById(R.id.textView1); mViewHolder.ivIcon = (ImageView) convertView .findViewById(R.id.imageView1); mViewHolder.tvTitle.setText(titles[position]); mViewHolder.ivIcon.setImageResource(images[position]); //Highlight the selected list item if (position == selectedposition[0]) { convertView.setBackgroundColor(Color.WHITE); mViewHolder.tvTitle.setTextColor(Color.BLUE); } else { convertView.setBackgroundColor(Color.TRANSPARENT); mViewHolder.tvTitle.setTextColor(Color.WHITE); } return convertView; } private class ViewHolder { TextView tvTitle; ImageView ivIcon; } }That's all, we have created Navigation Drawer, Now we have to attach Fragment for each item in Drawer, So first our HomeFragment class would be
Code:
HomeFragment.java
import android.app.Activity; import android.os.Bundle; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; public class HomeFragment extends Fragment { /** * Returns a new instance of this fragment for the given section number. */ public static HomeFragment newInstance() { HomeFragment fragment = new HomeFragment(); return fragment; } public HomeFragment() { } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_home, container, false); return rootView; } @Override public void onAttach(Activity activity) { super.onAttach(activity); ((MainActivity) activity).onSectionAttached(1); } }Now our MailFragment class would be
Code:
MailFragment.java
import android.app.Activity; import android.os.Bundle; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; public class MailFragment extends Fragment { /** * Returns a new instance of this fragment for the given section number. */ public static MailFragment newInstance() { MailFragment fragment = new MailFragment(); return fragment; } public MailFragment() { } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_mail, container, false); return rootView; } @Override public void onAttach(Activity activity) { super.onAttach(activity); ((MainActivity) activity).onSectionAttached(2); } }
And your
activity_main.xml
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.android.navigationdrawer.MainActivity" > <!-- As the main content view, the view below consumes the entire space available using match_parent in both dimensions. --> <FrameLayout android:id="@+id/container" android:layout_width="match_parent" android:layout_height="match_parent" /> <!-- android:layout_gravity="start" tells DrawerLayout to treat this as a sliding drawer on the left side for left-to-right languages and on the right side for right-to-left languages.

<ListView 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" android:background="#333333" android:choiceMode="singleChoice" android:divider="@android:color/transparent" android:dividerHeight="0dp" tools:context="com.android.navigationdrawer.NavigationDrawerFragment" />
And your
drawer_list.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" > <ImageView android:id="@+id/imageView1" android:layout_width="0dp" android:layout_height="fill_parent" android:layout_margin="10dp" android:layout_weight=".5" android:src="@drawable/home_blue" /> <TextView android:id="@+id/textView1" android:layout_width="0dp" android:layout_height="fill_parent" android:layout_margin="10dp" android:layout_marginLeft="5dp" android:layout_weight="1.5" android:gravity="left|center_vertical" android:text="TextView" /> </LinearLayout>
And your
fragment_home.xml
<LinearLayout 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" android:background="#0200E4" android:gravity="center" tools:context="com.android.navigationdrawer.MainActivity$HomeFragment" > <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="You are in home fragment!" android:textColor="#ffffff" android:textSize="20sp" android:textStyle="bold|italic" /> </LinearLayout>
And your

And your
res/menu/global.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" > <item android:id="@+id/action_settings" android:orderInCategory="100" android:title="@string/action_settings" app:showAsAction="never"/> </menu>

If you want to customize your ActionBar try the following code.
Create a xml called
res/values/myactionbar.xml
<?xml version="1.0" encoding="utf-8"?> <resources> <!-- the theme applied to the application or activity --> <style name="CustomActionBarTheme" parent="@style/Theme.AppCompat"> <!-- Support library compatibility --> <item name="actionBarStyle">@style/MyActionBar</item> <item name="actionBarTabTextStyle">@style/MyActionBarTabText</item> <item name="actionMenuTextColor">@android:color/white</item> </style> <!-- ActionBar styles --> <style name="MyActionBar" parent="@style/Widget.AppCompat.ActionBar"> <!-- Support library compatibility --> <item name="titleTextStyle">@style/MyActionBarTitleText</item> <item name="background">@drawable/actionbar_background</item> </style> <!-- ActionBar title text --> <style name="MyActionBarTitleText" parent="@style/TextAppearance.AppCompat.Widget.ActionBar.Title"> <item name="android:textColor">@android:color/white</item> </style> <!-- ActionBar tabs text --> <style name="MyActionBarTabText" parent="@style/Widget.AppCompat.ActionBar.TabText"> <item name="android:textColor">@android:color/white</item> <!-- The textColor property is backward compatible with the Support Library --> </style> </resources>
And your
res/drawable/actionbar_background.xml
<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" > <solid android:color="#333333" /> </shape>
