Android Sliding Drawer not Working

Android Sliding Drawer not Working - android

I have Implented Drawer with a SLider listner
But it does not work when swapping fingers Please Tell Me What i am doing wrong:
here is my frag class
public class frag extends android.support.v4.app.Fragment{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
View view = inflater.inflate( R.layout.lists , container);
return view;
}
public void setUp(int Fid ,DrawerLayout drawerLayout)
{
drawerLayout = (DrawerLayout)getActivity().findViewById(R.id.drawer);
drawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
final ActionBar ab = getActivity().getActionBar();
ActionBarDrawerToggle abdl = new ActionBarDrawerToggle(
getActivity(),
drawerLayout,
R.string.action_settings ,
R.string.hello_world) {
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
ab.setTitle("closed");
}
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
ab.setTitle("opened");
}
};
drawerLayout.setDrawerListener(abdl);
}
public void close()
{
DrawerLayout drawerLayout = (DrawerLayout)getActivity().findViewById(R.id.drawer);
drawerLayout.closeDrawers();
}
}
here is the layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="240dp"
android:id="#+id/dll"
android:layout_height="match_parent">
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:gravity="right"
android:id="#+id/drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
>
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/sidebarlist"
android:text="thadssasdisk"
android:textAlignment="center">
</ListView>
</android.support.v4.widget.DrawerLayout>
Slider is not working, I want to create a side Navigation Drawer class
The Activity:
package com.example.shubham.navigation;
import android.content.Context;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.Layout;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.TextView;
import java.util.List;
public class MainActivity extends AppCompatActivity {
DrawerLayout dl;
frag fg;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
fg = (frag)getSupportFragmentManager().findFragmentById(R.id.sidebar);
fg.setUp(R.id.drawer, (DrawerLayout) findViewById(R.id.drawer));
ListView lv = (ListView)findViewById(R.id.sidebarlist);
drawer aa = new drawer(this);
lv.setAdapter(aa);
aa.add("text");
aa.add("fun");
aa.add("learn");
aa.add("To do");
aa.add("Pending");
aa.add("Current");
aa.add("future");
aa.add("Learn");
aa.add("tasks");
aa.notifyDataSetChanged();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
protected void onPostCreate(Bundle savedInstanceState)
{
super.onPostCreate(savedInstanceState);
fg.onViewStateRestored(savedInstanceState);
fg.abdl.syncState();
}
}
the alyout file wher fragment is called:
<RelativeLayout 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"
tools:context=".MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/tview"
android:text="hello world you know who"
android:visibility="invisible"
/>
<fragment
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/sidebar"
class="com.example.shubham.navigation.frag"
></fragment>
</RelativeLayout>

Your implementation for NavigationDrawer is completely wrong. You should call setup() from your parent activity's onCreate() function to initialize ActionBar and NavigationDrawer.
Sample code is given below:
public class MainActivity extends Activity {
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mDrawerToggle;
...
public void onCreate(Bundle savedInstanceState) {
...
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
mDrawerLayout, /* DrawerLayout object */
R.drawable.ic_drawer, /* nav drawer icon to replace 'Up' caret */
R.string.drawer_open, /* "open drawer" description */
R.string.drawer_close /* "close drawer" description */
) {
/** Called when a drawer has settled in a completely closed state. */
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
getActionBar().setTitle(mTitle);
}
/** Called when a drawer has settled in a completely open state. */
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
getActionBar().setTitle(mDrawerTitle);
}
};
// Set the drawer toggle as the DrawerListener
mDrawerLayout.setDrawerListener(mDrawerToggle);
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Pass the event to ActionBarDrawerToggle, if it returns
// true, then it has handled the app icon touch event
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
// Handle your other action bar items...
return super.onOptionsItemSelected(item);
}
}
Android docs: http://developer.android.com/training/implementing-navigation/nav-drawer.html

When I implemented this, I used the following code with the help of this tutorial:
sliding menu tutorial
Drawer Adapter
public class NavDrawerListAdapter extends BaseAdapter {
private Context context;
private ArrayList<NavDrawerItem> navDrawerItems;
public NavDrawerListAdapter(Context context, ArrayList<NavDrawerItem> navDrawerItems){
this.context = context;
this.navDrawerItems = navDrawerItems;
}
#Override
public int getCount() {
return navDrawerItems.size();
}
#Override
public Object getItem(int position) {
return navDrawerItems.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater)
context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.drawer_list_item, null);
}
ImageView imgIcon = (ImageView) convertView.findViewById(R.id.icon);
TextView txtTitle = (TextView) convertView.findViewById(R.id.title);
TextView txtCount = (TextView) convertView.findViewById(R.id.counter);
imgIcon.setImageResource(navDrawerItems.get(position).getIcon());
txtTitle.setText(navDrawerItems.get(position).getTitle());
// displaying count
// check whether it set visible or not
if(navDrawerItems.get(position).getCounterVisibility()){
txtCount.setText(navDrawerItems.get(position).getCount());
}else{
// hide the counter view
txtCount.setVisibility(View.GONE);
}
return convertView;
}
}
Main Activity
public class MainActivity extends Activity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
// nav drawer title
private CharSequence mDrawerTitle;
// used to store app title
private CharSequence mTitle;
// slide menu items
private String[] navMenuTitles;
private TypedArray navMenuIcons;
private ArrayList<NavDrawerItem> navDrawerItems;
private NavDrawerListAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTitle = mDrawerTitle = getTitle();
// load slide menu items
navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);
// nav drawer icons from resources
navMenuIcons = getResources()
.obtainTypedArray(R.array.nav_drawer_icons);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.list_slidermenu);
navDrawerItems = new ArrayList<NavDrawerItem>();
// Home
navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(0, -1)));
navDrawerItems.add(new NavDrawerItem(navMenuTitles[1], navMenuIcons.getResourceId(1, -1)));
navDrawerItems.add(new NavDrawerItem(navMenuTitles[2], navMenuIcons.getResourceId(2, -1)));
navDrawerItems.add(new NavDrawerItem(navMenuTitles[3], navMenuIcons.getResourceId(3, -1));
navDrawerItems.add(new NavDrawerItem(navMenuTitles[4], navMenuIcons.getResourceId(4, -1)));
navDrawerItems.add(new NavDrawerItem(navMenuTitles[5], navMenuIcons.getResourceId(5, -1)));
navMenuIcons.recycle();
// setting the nav drawer list adapter
adapter = new NavDrawerListAdapter(getApplicationContext(),
navDrawerItems);
mDrawerList.setAdapter(adapter);
// enabling action bar app icon and behaving it as toggle button
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_drawer, //nav menu toggle icon
R.string.app_name, // nav drawer open - description for accessibility
R.string.app_name // nav drawer close - description for accessibility
){
public void onDrawerClosed(View view) {
getActionBar().setTitle(mTitle);
// calling onPrepareOptionsMenu() to show action bar icons
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle(mDrawerTitle);
// calling onPrepareOptionsMenu() to hide action bar icons
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
if (savedInstanceState == null) {
// on first time display view for first nav item
displayView(0);
}
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
// if nav drawer is opened, hide the action items
boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
menu.findItem(R.id.action_settings).setVisible(!drawerOpen);
return super.onPrepareOptionsMenu(menu);
}
#Override
public void setTitle(CharSequence title) {
mTitle = title;
getActionBar().setTitle(mTitle);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Pass any configuration change to the drawer toggls
mDrawerToggle.onConfigurationChanged(newConfig);
}
You then need to add the code for each fragment and the required resources respectively.
The xml layout file for the navigation slider would be similar to the one below:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="48dp"
android:background="#drawable/list_selector">
<ImageView
android:id="#+id/icon"
android:layout_width="25dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginLeft="12dp"
android:layout_marginRight="12dp"
android:contentDescription="#string/desc_list_item_icon"
android:src="#drawable/ic_home"
android:layout_centerVertical="true" />
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_toRightOf="#id/icon"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:textColor="#color/list_item_title"
android:gravity="center_vertical"
android:paddingRight="40dp"/>
<TextView android:id="#+id/counter"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/counter_bg"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="8dp"
android:textColor="#color/counter_text_color"/>
</RelativeLayout>

Android : Button to open Navigation Layout not shown

I am working on an Android application in which I am trying to integrate the Navigation Drawer. The navigation drawer is there, but there is no button for that to open or close it, I just have to drag it via a finger outside. I don't know what I am doing wrong. Any help would be nice.
To integrate the Drawer, I have an activity class, which I am extending instead of Activity to show the drawer within.
Below is the class which is extended by all activities where I want a drawer.
Here is the RestaurantDrawerActivity class :

Here is the screenshot showing that the button is not there :

Replace your code line
mDrawerLayout.setDrawerListener(mDrawerToggle);
To
mDrawerLayout.setDrawerListener(mDrawerToggle);
mDrawerToggle.syncState();

So you don't use the set() method that these
// enabling action bar app icon and behaving it as toggle button
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
two lines aren't executed.
I think these two lines (especially the first one) are needed to show the home button.

Not sure if it'll help but I've noticed the lack of super.onDrawerClosed and super.onDrawerOpened calls in your code and you could get some errors because of that. So, try changing your code to:
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
getSupportActionBar().setTitle(mTitle);
// calling onPrepareOptionsMenu() to show action bar icons
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
getSupportActionBar().setTitle(mDrawerTitle);
// calling onPrepareOptionsMenu() to hide action bar icons
invalidateOptionsMenu();
}

Menu Icon Is never shown

I am trying to show an icon in my action Bar. It is never shown.
My app is working fine. Even the function of the action bar button works as well. Am I missing Something ?
So Far. I added an action bar button as the following :
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"

I tried a lot of codes.
I figured out I have to make this code
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MyActivity" >
to this one
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
Even though it is giving me a strange error in the menu.xml but it works well

Null pointer exception Sliding Menu Fragment View

I am attempting to update my main activity to support toolbar and a more material navigation drawer from this example on on Androidhive http://www.androidhive.info/2013/11/android-sliding-menu-using-navigation-drawer/
This all worked before trying the conversion. Help or guidance is greatly appreciated
I am getting this in my error log.

Extend your MainActivity class using AppCompatActivity.
Then change the following lines:
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
With:
assert getSupportActionBar() != null;
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
And this line inside setTitle() function:
getActionBar().setTitle(mTitle);
To:
getSupportActionBar().setTitle(mTitle);
