Adding icon to toolbar Android - android

I am trying to add an icon to my toolbar using these two lines
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setIcon(R.drawable.logo);
The icon is added, however it's added in the center of the toolbar, how can I add it to the right corner of the toolbar for example?
This is my action_bar_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/app_name"
android:textColor="#ffffff"
android:id="#+id/action_bar_text"
android:textSize="18sp" />
</LinearLayout>

There is no direct way to set icon towards RIGHT in toolbar. An alternate way is to make use of Menu.
You can do the following
Create a Menu.xml in res/menu.xml folder
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item android:id="#+id/menu_item"
android:icon="#drawable/logo"
app:showAsAction="always"/>
</menu>
In the Activity Implement the following method.
#Override
public boolean onCreateOptionsMenu(Menu menu){
getMenuInflater().inflate(R.menu.right_menu, menu);
return super.onCreateOptionsMenu(menu);
}
Now with the above changes, you will see the icon on the right side of toolbar.
You can implement the tap by using the below method:-
#Override
public boolean onOptionsItemSelected(MenuItem item){
switch(item.getItemId()){
case R.id.menu_item: //this item has your app icon
Toast.makeText(this,"Tapped on icon",Toast.LENGTH_SHORT).show();
return true;
default: return super.onOptionsItemSelected(item);
}
}

How to get action bar three dots view reference

I need to get the View representing the three dots on the action bar.
(The reason I want the view reference is to pass it to a showcase library to show the showcaseView.)
No luck finding a solution. Any idea how to do that?
You can add the 3 dots using the below code. Add the below lines in your layout file.
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:textColor="#color/colorPrimaryDark"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:paddingLeft="25dp"
android:paddingRight="15dp"
android:text="⋮"
android:textAppearance="?android:textAppearanceLarge"
android:textSize="25dp" />
Value in android:text field helps you display the 3 vertical dots
known as vertical-ellipsis.

You can use the TextView now to perform your further actions. I hope this is what you are looking for. Comment if you are stuck with anything. Thank-You.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.activity_main_actions, menu);
return super.onCreateOptionsMenu(menu);
}
Try to add this code in main activity after adding a view activity_main_actions.xml in res/menu like as below
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- Search / will display always -->
<item android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:title="#string/action_search"
android:showAsAction="ifRoom"/>
</menu>

How to make the three dots appear in the Android toolbar

I am new in Android applications development, and I am trying to develop an application in UI I added a toolbar but In don't know why the three dots in the right side of the toolbar, it is necessary for me because I want to add a logout button there.
here is the toolbar layout:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="wrap_content"
android:background="#000">
</android.support.v7.widget.Toolbar>
And here is where i add the toolbar inside the activity class:
toolbar= (Toolbar) findViewById(R.id.app_bar);
setSupportActionBar(toolbar);
toolbar.setTitle(R.string.app_name);
toolbar.setTitleTextColor(getResources().getColor(R.color.com_facebook_button_background_color_focused));
and this is my menu.xml:
<?xml version="1.0" encoding="utf-8"?>
<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=".HomeActivity">
<item android:id="#+id/action_settings"
android:title="Settings"
android:orderInCategory="100"
app:showAsAction="always"
android:icon="#drawable/icon"
/>
<item
android:id="#+id/action_search"
android:title="Search">
</item>
</menu>
And what is weird is that in the android studio preview the three dots are shown:
what I am doing wrong ?
Create Android Resource Directory of type menu in res folder and add xml file named: user_menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/logout_menu"
android:orderInCategory="100"
android:title="#string/action_logout"
app:showAsAction="never" />
</menu>
In your Activity:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.user_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.logout_menu:
// Do whatever you want to do on logout click.
return true;
default:
return super.onOptionsItemSelected(item);
}
}
The three dots were hidden because they were black, and the toolbar background is black, so I had to add this white theme
android:theme="#style/ThemeOverlay.AppCompat.Dark"
to my toolbar layout.
In onCreateOptionmenu() one file will be inflating automatically. Remove that file and three dots will be removed.
Or
If this function is not included in your activity file then remove the file under res\menu folder.

How to create a button in ActionBar with icon and text?

I want to create a button in ActionBar with text and icon. Something like on the screenshot below.
I've tried this code. But it doesn't work. It displays only icon without text.
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/create"
android:title="#string/create"
android:icon="#drawable/ic_apply"
android:showAsAction="always|withText" />
</menu>
Read up on Toolbar
Since Toolbar is basically a ViewGroup, you can add child views. An example :
<Toolbar
android:id = "#+id/myToolbar"
android:layout_height = "wrap_content"
android:layout_width = "match_parent"
android:minHeight = "?attr/actionBarSize"
android:background = "?attr/colorPrimary" >
<Button
android:layout_height = "wrap_content"
android:layout_width = "match_parent"
android:text = "My button"
android:layout_gravity = "right" />
</Toolbar>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- Search, should appear as action button -->
<item android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:title="#string/action_search"
android:showAsAction="ifRoom" />
</menu>
If you mentioned android:showAsAction="ifRoom"
it is considered as Action bar button.
Inflating Menu:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu items for use in the action bar
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_activity_actions, menu);
return super.onCreateOptionsMenu(menu);
}
Handling Click event:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle presses on the action bar items
switch (item.getItemId()) {
case R.id.action_search:
openSearch();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
Assuming you are using AppCompat:
Your question maybe similar to: https://stackoverflow.com/a/18262141/950427
Make sure you bringing in the correct namespace: xmlns:yourapp="http://schemas.android.com/apk/res-auto".
Here is the example from the docs:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:yourapp="http://schemas.android.com/apk/res-auto" >
<item android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:title="#string/action_search"
yourapp:showAsAction="ifRoom" />
...
</menu>
Explanation from the docs:
Using XML attributes from the support library Notice that the
showAsAction attribute above uses a custom namespace defined in the
tag. This is necessary when using any XML attributes defined by
the support library, because these attributes do not exist in the
Android framework on older devices. So you must use your own namespace
as a prefix for all attributes defined by the support library.
Documentation: http://developer.android.com/guide/topics/ui/actionbar.html#ActionItems
You can create different xml layout for actionbar and in that use buttons or text.
Example:
actionbar.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:orientation="vertical">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Enter Text"
android:textColor="#ffffff"
android:textStyle="bold"
android:textSize="#dimen/actionbar_title"/>
</LinearLayout>
use actionbar.xml in java file:
DisplayMetrics metrics = getResources().getDisplayMetrics();
ActionBar actionbar = getActionBar();
Drawable d=getResources().getDrawable(R.drawable.action2);
getActionBar().setBackgroundDrawable(d);
getActionBar().setIcon(android.R.color.transparent);
TextView title;
getActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
getActionBar().setCustomView(R.layout.actiobar);
title= (TextView)findViewById(R.id.title);
title.setText("BUSINESS");

Is it possible to Implement Toggle Button in Action Menu Item using Actionbar sherlock in android

I have an app, which have toggle button in action menu item, though i'm using Actionbar Sherlock, I don't know, how to place the toggle button in the action menu item. I don't want to place as a custom layout in action bar, but i want to place it as a Menu item. If anyone find solution, Please help me out.
Purpose, If I change the state of toggle button, it will sort the person based on ALphabets and again in Date of Birth.
Thanks in Advance!
Just add it like a normal Menu Button, check its state with a boolean variable, and you can change the icon and title when changing the sortmode
boolean birthSort=false;
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_toggle:
if(birthSort){
//change your view and sort it by Alphabet
item.setIcon(icon1)
item.setTitle(title1)
birthSort=false;
}else{
//change your view and sort it by Date of Birth
item.setIcon(icon2)
item.setTitle(title2)
birthSort=true;
}
return true;
}
return super.onOptionsItemSelected(item);
}
Don't forget to add it in xml like any other menu button and configure android:showAsAction if you want to show it in overflow or outside of it.
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/menu_toogle"
android:showAsAction="ifRoom"
android:title="Share"
/>
</menu>
Other approach would be to use a custom layout for your ActionBar:
Basically you define a layout that contains your Toggle:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ToggleButton
android:id="#+id/actionbar_service_toggle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textOn="Logging On"
android:textOff="Logging Off" />
</RelativeLayout>
ALTERNATIVE 1:
Then in your Activity or Fragment container you do:
ActionBar actionBar = getSupportActionBar();
actionBar.setCustomView(R.layout.actionbar_top);
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_HOME | ActionBar.DISPLAY_SHOW_CUSTOM);
...
ToggleButton button = (ToggleButton) findViewById(R.id.actionbar_service_toggle);
Notice that you are having a real ToggleButton and you are handling it in code as a real object ToggleButton, which has lots of advantages compared to having you re-implement your own toggle (theme, reliability, views hierarchy, native support...).
Source code here.
ALTERNATIVE 2:
Another way to do it is embed your custom view into a regular menu view:
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/myswitch"
android:title=""
android:showAsAction="always"
android:actionLayout="#layout/actionbar_service_toggle" />
</menu>
If like me the actionLayout isn't working for you, try app:actionLayout="#layout/actionbar_service_toggle" instead of android:actionLayout="#layout/actionbar_service_toggle" as well as app:showAsAction="always" instead of android:showAsAction="always"
This is because if you use appCompat the android namespace won't be used.
So here's the final version:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ToggleButton
android:id="#+id/actionbar_service_toggle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textOn="Logging On"
android:textOff="Logging Off" />
</RelativeLayout>
and
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/myswitch"
android:title=""
app:showAsAction="always"
app:actionLayout="#layout/actionbar_service_toggle" />
</menu>
create xml file in menu:
menu.xml
<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="si.ziga.switchinsideab.MainActivity">
<item android:id="#+id/switchId" android:title="" android:showasaction="always" android:actionlayout="#layout/switch_layout">
<item android:id="#+id/action_settings" android:orderincategory="100" android:title="#string/action_settings" app:showasaction="never">
</item></item></menu>
And then navigate to your layout folder make a new xml file
and name it switch_layout.xml
Here's the code:
switch_layout.xml
<!--?xml version="1.0" encoding="utf-8"?-->
<relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="match_parent" android:orientation="horizontal">
<switch android:id="#+id/switchAB" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerhorizontal="true" android:layout_centervertical="true">
</switch></relativelayout>
In your MainActivity class copy and paste this code:
MainActivity.java
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
switchAB = (Switch)menu.findItem(R.id.switchId)
.getActionView().findViewById(R.id.switchAB);7
Or follow this link about this stuff
Here somthing easy
<?xml version="1.0" encoding="utf-8"?>
<item
android:title="#string/mode"
android:id="#+id/switch1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:switchMinWidth="56dp"
android:layout_marginTop="120dp"
app:showAsAction="ifRoom"
app:actionViewClass="androidx.appcompat.widget.SwitchCompat"
android:checked="false"/>

Center SearchView in Action Bar

How can I center an ActionView (a SearchView in particular) inside of a Action Bar?
As seen in the Google Books app:
My current layout setup (search_layout.xml):
<?xml version="1.0" encoding="utf-8"?>
<SearchView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:queryHint="#string/search_hint" />
My Action Bar XML file (menu.xml):
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:icon="#+android:drawable/ic_menu_search"
android:title="#string/search"
android:showAsAction="always|collapseActionView"
android:id="#+id/searchMenuItem"
android:actionLayout="#layout/search_layout" />
</menu>
Is there a way to mimic the behaviour of the Books' SearchView?
A View centered in the ActionBar can't be achieved with Action Items in an xml menu, as far as I can tell. However it can be implemented by setting a custom layout to the ActionBar. A basic example:
An Activity:
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ActionBar actionBar = getActionBar();
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
actionBar.setDisplayShowHomeEnabled(true);
actionBar.setCustomView(R.layout.actionbar_layout);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
where actionbar_layout is:
<?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="match_parent">
<SearchView
android:id="#+id/mySearchView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:iconifiedByDefault="false" />
</RelativeLayout>
creates this on a 7'' tablet:
Note the iconifiedByDefault attribute set to false on the SearchView which forces it to appear expanded and not just as an icon. This may require that you hide the softkeyboard programmatically or it will be launched open when the Activity starts.
Have a look here. You can just use the android:actionViewClass="android.widget.SearchView" attribute, and that should work just fine (keep in mind that you can get a reference to the searchView in Java, and change the hint there if that's what you want).
