Android- app crashes while adding a navigation drawer to a custom toolbar - android

I've made a custom toolbar and its Right-To-Left. and it looks like this:
I want a navigation drawer appears when I click on the right side icon. But when I add the navigation drawer to app, it crashes. I've tried many things and also searched a lot, but it didn't work.
It'd be GREAT it someone would help me.

now I have this toolbar when I click on the right side icon the drawer opens & closes,
right side drawer

android.widget.ListView.setAdapter(android.widget.ListAdapter)' on a

com.playpersia.mycustomizedtoolbar.MainActivity.onCreate(MainActivity.java:53)
In onCreate method, your listView object is null.
You need to add
listView = (ListView) findViewById(R.id.list_view);
before
listView.setAdapter(new ArrayAdapter<String (this,R.layout.drawer_list_item,pages));
UPDATE:
Change your activity_main.xml to:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<include
layout="#layout/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/toolbar"/>
<android.support.v4.widget.DrawerLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:openDrawer="end"
android:fitsSystemWindows="true"
android:id="#+id/right_drawer">
<!-- Main layout -->
<FrameLayout
android:id="#+id/main_fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/toolbar"
android:text="Hello"/>
</FrameLayout>
<!-- Nav drawer -->
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="left|start" >
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/header_drawer"
android:src="#drawable/my_image" />
<ListView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="end"
android:id="#+id/list_view"
android:entries="#array/pages" />
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
</LinearLayout>

This should be your MainLayout since you are using DrawerLayout:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/right_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<!-- Your contents, for example, CoordinatorLayout with material design -->
<!-- And after main Contents, here you can use NavigationDrawer also -->
</android.support.v4.widget.DrawerLayout>
And instead of commented code, use your contents.
You did it in wrong way, Take a look:
http://developer.android.com/training/implementing-navigation/nav-drawer.html#DrawerLayout
To add a navigation drawer, declare your user interface with a
DrawerLayout object as the root view of your layout. Inside the
DrawerLayout, 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.
For example, the following layout uses a DrawerLayout with two child
views: a FrameLayout to contain the main content (populated by a
Fragment at runtime), and a ListView for the navigation drawer.
Example:
<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">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- The navigation drawer -->
<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>
You may want to take a look at the Material Design Guidelines for this implementation of course:
https://www.google.com/design/spec/patterns/navigation-drawer.html

Why does the toolbar disappear when the background of the fragment is set to a certain color?

I'm working on a drawer layout. I want to replace the main activity screen with a fragment when I click a menu item, but it doesn't show a toolbar when I set the background of a fragment on some color app. Work done so far ...

This is fine when there is no background attribute but toolbar disappears when I add it

<TextView

android:textSize="30sp"
android:textColor="#android:color/black"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is sport section"
/>
</FrameLayout>
You are using relative layout so you have to position every single child in relative layout since you are not doing it. framelayout overlapping the toolbar when there is not color in framelayout toolbar visible to you and it does not go anywhere so whenever you add a color toolbar becomes invisible to you but not from screen it will be under the framelayout...
so add below line in framelayout
android:layout_below="#id/toolbar"

Bottom Sheet is not getting overlayed on bottom App bar

Result I got:
This is the result
Result I wanted:
See in this the frame layout as bottom sheet is overlaying on bottom app bar
Someone please help me
You need to set BottomSheet's elevation more than BottomAppBar's.
Elevation means how your views lay above each other

How to reference ID from other layout

Following this tutorial I moved my ActionBar (Toolbar) from my main layout to another layout and I include the toolbar to my main layout like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.marcelo.notemuevas.MainActivity">
<include
layout="#layout/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#id/my_toolbar">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Servicios"
android:id="#+id/serviciosTxt"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:background="#color/colorPrimaryDark"
android:textColor="#FFFFFF"
android:gravity="center"
android:paddingTop="18dp"
android:paddingBottom="18dp"
/>
<ListView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/serviciosTxt">
</ListView>
</RelativeLayout>
</RelativeLayout>
And my toolbar layout is this:
<?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:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="#+id/my_toolbar"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:elevation="4dp"
android:theme="#style/CustomActionBarTheme"/>
</LinearLayout>
But I got the following error
Why I cant make reference of my toolbar if it has the same id? Can I include my toolbar and make reference so I can put elements below the toolbar?
Edit 1 - Activity Code
package com.marcelo.notemuevas;
import android.content.Intent;

String Slecteditem = itemname[position];
Toast.makeText(getApplicationContext(), Slecteditem, Toast.LENGTH_SHORT).show();
Intent myIntent = new Intent(MainActivity.this, carpinteria.class);
myIntent.putExtra("key", 5); //Optional parameters
MainActivity.this.startActivity(myIntent);
}
});
}
public boolean onCreateOptionsMenu(Menu menu){
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu, menu);
return true;
}
}
Edit 2 - Solution
Now I make it work, I added a new Id to the include then I make reference to it like James Lockhart and Phan Văn Linh suggest (dont know why the first time didnt work) so my new question is, the IDs works like variables? only exist where it has been declared?
This is the working xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.marcelo.notemuevas.MainActivity">
<include
layout="#layout/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/toolbarLayout"
/>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#id/toolbarLayout">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Servicios"
android:id="#+id/serviciosTxt"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:background="#color/colorPrimaryDark"
android:textColor="#FFFFFF"
android:gravity="center"
android:paddingTop="18dp"
android:paddingBottom="18dp"
/>
<ListView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/serviciosTxt">
</ListView>
</RelativeLayout>
</RelativeLayout>
In your XML
<include
android:id=#"+id/toolBarLayout" // set the id for layout that contains toolbar
layout="#layout/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#id/toolBarLayout"> // change my_toolbar to toolBarLayout
Then you access to your Toolbar by change
Toolbar myToolbar = (Toolbar) findViewById(R.id.my_toolbar);
to
LinerLayout myLinear = (LinerLayout) findViewById(R.id.toolBarLayout);
Toolbar myToolbar = (Toolbar) myLinear.findViewById(R.id.my_toolbar);
Please try this:
In your toolbar layout file, in the LinearLayout tag, set the 'android:id' attribute to a unique layout id name, for example: android:id="#+id/toolbarLayout"
Once you have completed (1), in your main layout refer to your toolbar layout file as follows: android:layout_below="#id/toolbarLayout"
Hope this helps.

Navigation Drawer not working my Code in Android?

I am working with Navigation Drawer in Android.I have code from some examples.In my code working to change the drawer open and drawer close title but the panel is not open.I not insert the ListView array. My main Problem is not open the panel.Is anything I missed in the code?

DrawerLayout expects it's first child to be the actual layout and the second one to be the drawer. So, to make it work you should change your layout to (assuming that your entire drawer consists of only one ListView):
<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">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:layout_height="150dp"
android:layout_width="match_parent"
android:id="#+id/toolbar"
android:background="?attr/colorPrimary"
android:minHeight="?android:attr/actionBarSize"/>
</LinearLayout>
<ListView
android:id="#+id/drawer_list"
android:layout_width="240dp"
android:layout_height="match_parent"
android:background="#000000"
android:layout_gravity="start"/>
</android.support.v4.widget.DrawerLayout>
It looks like your xml layout needs to be re-arranged. The DrawerLayout should wrap two items; 1) a View or ViewGroup to set as the page content (e.g., RelativeLayout containing a Toolbar and Fragment container); 2) a View or ViewGroup that holds your NavigationDrawer items (e.g., ListView).
<android.support.v4.widget.DrawerLayout
android:id="#+id/navigation_drawer_layout"
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">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="#+id/your_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:background="#color/your_toolbar_color"
android:minHeight="?attr/actionBarSize"/>
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/your_toolbar"/>
</RelativeLayout>
<ListView
android:id="#+id/your_drawer_list"
android:layout_width="#dimen/drawer_width"
android:layout_height="match_parent"
android:layout_gravity="left"
android:background="#color/your_drawer_color"
android:divider="#null"/>
</android.support.v4.widget.DrawerLayout>
You can get a more detailed explanation and examples here:
https://developer.android.com/training/implementing-navigation/nav-drawer.html
If your list is empty and you have the height as wrap_content, the height will be 0. Changing it to match_parent will have it fill the screen regardless of the content.
<ListView
android:id="#+id/drawer_list"
android:layout_width="240dp"
android:layout_height="match_parent"
android:background="#000000"
android:layout_gravity="start"/>

DrawerLayout prevents touch events on EditText

I have a DrawerLayout, which has an EditText and a ListView in it.
The problem is, that I cannot touch my EditText or ListView items. Instead of it
DrawerLayout recieves all the touch events. Clicking on any item in the DrawerLayout causes DrawerLayout to close (which I guess is the default onTouch method in the drawerlayout class)
<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/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/background" >
<-- my main layouts here -->
</FrameLayout>
<LinearLayout
android:id="#+id/left_linear"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
android:clickable="true"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:clickable="true"
android:orientation="horizontal" >
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#drawable/noborder"
android:clickable="true"
android:hint="search box 1"
android:padding="8dp"
android:singleLine="true" />
<ImageView
android:layout_width="40dp"
android:layout_height="40dp"
android:padding="5dp"
android:src="#android:drawable/ic_menu_search" />
</LinearLayout>
<ListView
android:id="#+id/left_drawer"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#111"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp" />
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
Try drawerlayout.requestDisallowInterceptTouchEvent(true) in your oncreate
Set Both edit text and text view explicitly as clickable .. then implement something like this for list view
/******************************Listener for Drawer***************/
private class DrawerItemClickListener implements ListView.OnItemClickListener
{
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
//your code here based on posotion
}
}
you can set the listener using something like this
DrawerList.setOnItemClickListener(new DrawerItemClickListener());
i found a similar problem i have update sdk and specially Extra Folder and it work fine.
I've test your code and it's working fine on my device.
Thanks i hope it help.
i have done something like this,
i have updated your code.
edittext can now take focus
create main.xml

Try to add your Edittext and textview of the layout in below lines
android:focusableInTouchMode="true"
android:focusable="true"
or
oncreate methos you use requestfocus(your element id);
thank you.
