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.

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"?>

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"

<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.
I'm so frustrated here. I've searched around and tried a bunch of different things here. I've just started this project and am trying to add options to the 3dot menu first. Heres my menu_main.xml:

I have no idea what to do, I'm just hoping I missed something stupid. Ive cleaned the project, and rebuild dozens of times. I'm just trying to run it and see if I get the options to show up.
The id should be like this
#+id/action_settings
yours is (without the + )
#id/action_settings

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.

}
#Override
public boolean onCreateOptionsMenu(Menu menu) {

return true;
}
#Override

}
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"

</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>
I tried to add two action buttons on the action bar, for visibility one is defined as:
android:showAsAction="ifRoom"
another one is defined as:
android:showAsAction="never"
The problem is I can see the ic_action_search icon but I could not see the ic_action_overflow icon. This is the main_activity_actions.xml in menu folder:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:MyFirstApp="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"
MyFirstApp:showAsAction="ifRoom" />
<!-- Settings, should always be in the overflow -->
<item android:id="#+id/action_settings"
android:icon="#drawable/ic_action_overflow"
android:title="#string/action_settings"
MyFirstApp:showAsAction="never" />
</menu>
and this is the Java code that includes the buttons:
#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_activity_actions, menu);
return super.onCreateOptionsMenu(menu);
//return true;
}
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);
}
}
So whats wrong with my code?
cheers
