Android Action Button not shown in action bar - java

I want to display an icon on the action bar. But it always comes in the overflow list. Could you please help me up with a solution. This is my code.
CreateScheduleActivity.java
package com.mpeers.ui;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.ActionBar;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.os.Build;
public class CreateScheduleActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.create_schedule);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.action_bar, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
action_bar.xml in menu folder
<?xml version="1.0" encoding="utf-8"?>
<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/plusicon"
android:title="CS"
android:showAsAction="ifRoom" />
<!-- Settings, should always be in the overflow -->
<item android:id="#+id/action_settings"
android:title="#string/action_settings"
android:showAsAction="never" />
</menu>

If you are using the appcompat support library, you need to define
xmlns:app="http://schemas.android.com/apk/res-auto"
in the parent tag and then use app:showAsAction for controlling the visibility of the action items.
If you are not using the appcompat support library, you can use the android:showAsAction tag for controlling the visibility of the action items.

define xmlns:app="http://schemas.android.com/apk/res-auto" in parent tag.
then use app:showAsAction="ifRoom"
Following is the example 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="com.taazi.android.MainActivity" >
<item
android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:title="#string/action_search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="ifRoom"/>
<item
android:id="#+id/action_right_drawer"
android:icon="#drawable/ic_action_play_over_video"
android:title="#string/action_right_drawer"
app:showAsAction="ifRoom"/>
</menu>

Menu won't show up. I don't know why

I'm just following another tutorial but the result is different. When I'm trying to run my apk, menu icon won't show up on primary layout (activity_main.xml) Anyone knows what I missed?
menu_main_activity.xml
<?xml version="1.0" encoding="utf-8"?>

});
if (notes != null && notes.size() > 0) { //check if we have any notes!
final NoteAdapter na = new NoteAdapter(this, R.layout.view_note_item, notes);
mListNotes.setAdapter(na);
//set click listener for items in the list, by clicking each item the note should be loaded into NoteActivity
mListNotes.setOnItemClickListener(new AdapterView.OnItemClickListener() {

}
});
} else { //remind user that we have no notes!
Toast.makeText(getApplicationContext(), "you have no saved notes!\ncreate some new notes :)"
, Toast.LENGTH_SHORT).show();
}
}
}
And, the last is my activity_main_note.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:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.example.lenovo.home.MainNote">
<ListView
android:id="#+id/main_listview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="visible" />
</LinearLayout>
UPDATE
This is my styles code
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
</resources>
This is my theme code for application.
I have just run your code and it works fine.
I am running it with the following theme in styles.xml:
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
</resources>
In manifest I have android:theme="#style/AppTheme" in the application tag.
And my Activity extends AppCompatActivity
Also check you have put the menu xml in res/menu folder.
The only thing I see but it is regarding the item being selected is that the return statement is wrong, but it doesn't have to do with the icons not appearing.
In onOptionsItemSelected(MenuItem item) you should return true if you handle the request or false if not.
Change it like this:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
boolean rtn = false;
switch (item.getItemId()) {
case R.id.action_create: //run NoteActivity in new note mode
startActivity(new Intent(this, NoteActivity.class));
rtn = true;
break;
case R.id.action_settings:
//TODO show settings activity
rtn = true;
break;
default:
rtn = super.onOptionsItemSelected(item);
}
return rtn;
}
See this question: Should "android: onOptionsItemSelected" return true or false
EDIT I
I see in your styles.xml you are extending Theme.AppCompat.Light.NoActionBar, which doesn't have an ActionBar.
In this case you can switch to a theme with an ActionBar as I am using or otherwise you need to add your own action bar to the layout using a Toolbar.

Adding icons to the ActionBar on Android

Im following the next tutorial: Adding Action Buttoms, I did it step by step but when I run my app doesn´t shows any icon. I was debugging but everything seems correct and I have any nullPointerException or something like that.
This is my mainActivity:
package com.training.training.appone;
import android.content.Intent;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.widget.EditText;
public class MyActivity extends ActionBarActivity {
public final static String EXTRA_MESSAGE = " com. training.example.appone.MESSAGE";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
//getMenuInflater().inflate(R.menu.menu_my, menu);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_activiy_actions, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
public void sendMessage(View view){
Intent intent = new Intent(this, DisplayMessageActivity.class);
EditText editText = (EditText) findViewById(R.id.txt_edit_message);
String message = editText.getText().toString();
// El primer parametro es el KeyName:
intent.putExtra(EXTRA_MESSAGE, message);
startActivity(intent);
}
}
And I put this XML:
<?xml version="1.0" encoding="utf-8"?>
<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" />
<!-- Settings, should always be in the overflow -->
<item android:id="#+id/action_settings"
android:title="#string/action_settings"
android:showAsAction="never" />
</menu>
I have an error in the last line "android:showsAsAction="never", I have the libray downloaded and referenced in my build gradle: compile 'com.android.support:appcompat-v7:22.0.0' I also tryed changed "android" to "res-auto", but it says that the items must have a title (they have them):
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/res-auto">
<!-- 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" />
<!-- Settings, should always be in the overflow -->
<item android:id="#+id/action_settings"
android:title="#string/action_settings"
android:showAsAction="never" />
</menu>
My library:
In this point I have no idea what happends.
Make the following changes in your menu.xml
<menu
....
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
...
app:showAsAction="never" />
</menu>
And if you want to display your menu on actionBar then it should be app:showAsAction="always".
In your XML file, Please change this line
app:showAsAction="always"
instead of
android:showAsAction="never"
Probably as you are using AppCompat library, you should use
app:showAsAction="never"
instead
android:showAsAction="never"
If you look at the xml schemas in the tutorial you have both:
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:yourapp="http://schemas.android.com/apk/res-auto"
Notice the xmlns:android and xmlns:yourapp are different. So all you need to do is:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:yourapp="http://schemas.android.com/apk/res-auto">
<!-- Search, should appear as action button -->
<item android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:title="#string/action_search"
yourapp:showAsAction="ifRoom" />
<!-- Settings, should always be in the overflow -->
<item android:id="#+id/action_settings"
android:title="#string/action_settings"
yourapp:showAsAction="never" />
</menu>
The android and yourapp tags can be named however you want. They are just a named reference to the schema.

Cant use Appbar with Buttons

I started working with the Holo Theme, and I want to build my app with this Theme (without using the Compact)
The problem is that my App bar is whithout the Buttons. (I cannot use the ifRoom option for showing the menus icons).
my menu 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=".MainActivity">
<item
android:id="#+id/action_settings"
android:orderInCategory="100"
android:title="#string/action_settings"
app:showAsAction="never" />
<item
android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:orderInCategory="105"
app:showAsAction="ifRoom"
android:title="#string/action_search"
/>
<item
android:id="#+id/action_edit"
android:icon="#drawable/ic_action_edit"
android:orderInCategory="110"
android:title="#string/action_edit"
app:showAsAction="ifRoom" />
and my Java Class:
package myfirsttry.another;
import android.app.Activity;
import android.content.Intent;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.EditText;
public class MainActivity extends Activity{
public final static String EXTRA_MESSAGE = "linir.key";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
public void sendMessage(View view){
Intent intent = new Intent(this, secondActivity.class);
EditText editText = (EditText)findViewById(R.id.etInput);
String message = editText.getText().toString();
intent.putExtra(EXTRA_MESSAGE,message);
startActivity(intent);
}
}
Thanks
The app:showAsAction is only applicable if you use AppCompat as is strongly recommended for compatibility and consistency across all API levels.
If you'd like to only use the system provided action bar, then you'd replace all instances of app:showAsAction with android:showAsAction.

No actions or icons showing on the actionbar; only in overflow

I'm not really new to programming but a complete fresh noob regarding android and java.
I recently made the decision to programm an Android App using this tutorial.
I got till the actionbar and can even display some actions like search and settings in the overflow. What I cant manage to do is to let an action appear on the actionbar(with or without icon).
I managed to it once with this tutorial but I somehow cant repeat it on my actual "Tutorialapp".
Here is my code:
main.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="com.example.newapp.MainActivity" >
<item
android:id="#+id/action_settings"
android:orderInCategory="100"
android:title="#string/action_settings"
app:showAsAction="never"/>
<item
android:id="#+id/action_search"
android:orderInCategory="1"
android:icon="#drawable/ic_action_search"
android:title="#string/action_search"
android:showAsAction="always"/>
</menu>
MainActivity.java:
package com.example.newapp;
import android.support.v7.app.ActionBarActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends ActionBarActivity {
public final static String EXTRA_MESSAGE = "com.example.newapp.MESSAGE";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
switch (item.getItemId()) {
case R.id.action_search:
openSearch();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
private void openSearch() {
Toast.makeText(this, "This is a Search Button", Toast.LENGTH_SHORT).show();
}
public void sendMessage (View view){
Intent intent = new Intent(this, DisplayMessageActivity.class);
EditText editText = (EditText) findViewById(R.id.edit_message);
String message = editText.getText().toString();
intent.putExtra(EXTRA_MESSAGE, message);
startActivity(intent);
}
}
try swapping the menu items:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:title="#string/action_search"
android:showAsAction="always"/>
<item
android:id="#+id/action_settings"
android:orderInCategory="101"
android:title="#string/action_settings"
app:showAsAction="never"/>
</menu>
I dont know why, but you need to specify in java code the action always. I had the same problem, and I solved it like that:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
menu.findItem(R.id.actionSearch).setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
return true;
}
Hope it solve your problem. :D!! Good Luck!

How to add action bar to Android app?

I just start with Android. Want to add action bar following the tutorial. I was added res/menu/main_activity_actions.xml:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:NecoSeparator="http://schemas.android.com/apk/res-auto" >
<!-- Search, should appear as action button -->
<item android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:title="#string/action_search"
NecoSeparator:showAsAction="ifRoom" />
<!-- Settings, should always be in the overflow -->
<item android:id="#+id/action_settings"
android:title="#string/action_settings"
android:showAsAction="never" />
In MainActivity.java i do:
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);
}
But Eclipse says that cant find : R.menu.main_activity_actions.
What's wrong with this code? I have to do something more with this xml file?
UPDATE
MainActivity.java
package com.example.necoseparator;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.widget.EditText;
public class MainActivity extends Activity {
public final static String EXTRA_MESSAGE = "com.example.myfirstapp.MESSAGE";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#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);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle presses on the action bar items
switch (item.getItemId()) {
case R.id.action_search:
openSearch();
return true;
case R.id.action_settings:
openSettings();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
public void sendMessage(View view) {
Intent intent = new Intent(this, DisplayMessageActivity.class);
EditText editText = (EditText) findViewById(R.id.edit_message);
String message = editText.getText().toString();
intent.putExtra(EXTRA_MESSAGE, message);
startActivity(intent);
}
}
I Think main problem is to saving your menu layout, if you have an error in file its might happened. please change your menu file with my code and save that and import R file (make sure that is not android.R and its must be YourPackageName.R) then clean your project and run.
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/action_settings"
android:orderInCategory="100"
android:showAsAction="never"
android:title="filtered"
/>
<item
android:id="#+id/menu_load"
android:icon="#drawable/ic_luncher"
android:orderInCategory="200"
android:showAsAction="always"
android:title="update"/>
</menu>
Remove this line xmlns:NecoSeparator="http://schemas.android.com/apk/res-auto and try again
<!-- Settings, should always be in the overflow -->
<item android:id="#+id/action_settings"
android:title="#string/action_settings"
android:showAsAction="never" />
</menu>
You can use Toolbar
toolbar = (Toolbar) findViewById(R.id.toolbar1);
setSupportActionBar(toolbar);
and add list of menus
