I have a search view in my activity. When I am trying to attach an OnQueryTextListener, it gives me a NullPointerException. Its Java code is as follows
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.allpurpose, menu);
MenuItem searchItem = menu.findItem(R.id.apmenu_search);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener() {
public boolean onQueryTextChange(String newText) {return true;}
public boolean onQueryTextSubmit(String query) {return true;}
};
searchView.setOnQueryTextListener(queryTextListener);
return super.onCreateOptionsMenu(menu);
}
XML Code:
<?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/apmenu_search"
android:icon="#android:drawable/ic_menu_search"
android:title="#string/srch"
android:showAsAction="ifRoom"
android:actionViewClass="android.support.v7.widget.SearchView" />
</menu>
All "Compat" items are used to provide backward compatibility. So in this case MenuItemCompat supports action bar items for versions above 7 (instead of the normal 11). In the java code, if there is MenuItemCompat, then in the xml too there must be a "Compat" item. Now, the "app" namespace supports these "Compat" items. So change the xml like this:
<?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/apmenu_search"
android:icon="#android:drawable/ic_menu_search"
android:title="#string/srch"
app:showAsAction="ifRoom"
app:actionViewClass="android.support.v7.widget.SearchView" />
</menu>

I am trying to get a 3 dot menu to show in my app but can't get it to work.
I have created a file called mymenu.xml under res/menu and the contents are:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/level"
android:title="#string/Level"
app:showAsAction="never">
</item>
</menu>
This is what is in my MainActivity.java file:
#Override
public boolean onCreateOptionsMenu(Menu my_menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.mymenu, my_menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.level:
levelMax = 41;
levelTextView.setText("Level:\nEasy");
mCountDownTimer.cancel();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
What am I doing wrong? Any help would be appreciated. Thanks.

}
});
return super.onCreateOptionsMenu(menu);
}
Can Anyone help me to solve this problem please.
ThankYou.
Lets not use SearchView directly, in your 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=".HomeActivity">
<item
android:id="#+id/action_search"
android:icon="#android:drawable/ic_menu_search"
android:title="Search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="always" />
</menu>
and add this simple code to your java :
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_search:
// Not implemented here
return false;
default:
break;
}
searchView.setOnQueryTextListener(queryTextListener);
return super.onOptionsItemSelected(item);
}
Main_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/action_search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="always|collapseActionView"
android:icon="#android:drawable/ic_menu_search"
android:title="Search" />
</menu>
onCreateOptionMenu method
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.search_view_menu_item, menu);
MenuItem searchViewItem = menu.findItem(R.id.action_search);
final SearchView searchViewAndroidActionBar = (SearchView) MenuItemCompat.getActionView(searchViewItem);
searchViewAndroidActionBar.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
searchViewAndroidActionBar.clearFocus();
return true;
}
#Override
public boolean onQueryTextChange(String newText) {
return false;
}
});
return super.onCreateOptionsMenu(menu);
}
I wanted to create an option menu which shows up similar to Whatsapp even if the device has its own "hardware" option button. The solution I found online worked just fine until I wanted to add another action to the Bar.
Menu:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:title=""
android:id="#+id/addViewedMovie"
android:icon="#mipmap/ic_add_to_queue_black_24px"
android:showAsAction="always"
></item>
<item
android:title=""
android:id="#+id/menu_overflow"
android:icon="#mipmap/ic_more_vert_white_48dp"
app:showAsAction="always">
<menu>
<item
android:id="#+id/show_settings"
app:showAsAction="never"
android:title="#string/setttings"/>
<item
android:id="#+id/show_help"
app:showAsAction="never"
android:title="#string/help"/>
<item
android:id="#+id/show_about"
app:showAsAction="never"
android:title="#string/about"/>
</menu>
</item>
</menu>
And this in my MainActivity:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
return true;
}
With this the app forces the addViewedMovie Action into an Overflow-Menu. Does anyone know how to prevent this?
Try this code and tell me if its work.. you should use app:showAsAction not android:showAsAction also you do not need to use submenu to show 3 dots.. just below code works fine also show 3 dots
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:title="Movie"
android:id="#+id/addViewedMovie"
android:icon="#mipmap/ic_add_to_queue_black_24px"
app:showAsAction="always"/>
<item
android:id="#+id/show_settings"
app:showAsAction="never"
android:title="#string/setttings"/>
<item
android:id="#+id/show_help"
app:showAsAction="never"
android:title="#string/help"/>
<item
android:id="#+id/show_about"
app:showAsAction="never"
android:title="#string/about"/>
</menu>
Create a folder name Menu in your res folder.
menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:myapp="http://schemas.android.com/apk/res-auto">
<item android:id="#+id/search"
android:icon="#drawable/ic_launcher"
myapp:showAsAction="ifRoom" />
<item android:id="#+id/abc"
android:title="ABC" />
<item android:id="#+id/abc1"
android:title="ABC1" />
<item android:id="#+id/abc2"
android:title="ABC2" />
</menu>
In java file put this:-
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.search:
return true;
case R.id.abc:
return true;
case R.id.abc1:
return true;
case R.id.abc2;
return true;
default:
return super.onOptionsItemSelected(item);
}
}
Simple.
use app instead of android as app is for design support library.
And so, in Gradle build in dependencies, you must have: compile com.android.support:design..... like that. But, I have seen that you already used it below. So,
Just use: app:showAsAction="never" instead of android:showAsAction="always" in your addViewedMovie item.
Remember: never means it will be on overflow menu item. always means is will show in action bar.
If you are using in a fragment, add below line in the onCreate
setHasOptionsMenu(true);
And two more functions
#Override public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
}
Inflate your views in the above method. Listen to the action in the below one.
#Override public boolean onOptionsItemSelected(MenuItem item) {
return super.onOptionsItemSelected(item);
}
I am having trouble setting the menu item text. I want when I start the activity to see the price of all my items in the basket. But whenever I start the shopping list activity I get below error:
java.lang.NullPointerException: Attempt to invoke interface method 'android.view.MenuItem android.view.Menu.findItem(int)' on a null object reference
This is the code:
public class Shopping_list_activity extends AppCompatActivity{
private Menu menu;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.shopping_list_activity);
updateMenuTitles();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
getMenuInflater().inflate(R.menu.menu_shopping_list, menu);
this.menu = menu;
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.menu_shopping_list_saveList) {
Toast.makeText(Shopping_list_activity.this, " Clicked", Toast.LENGTH_SHORT).show();
}
// else if (id == R.id.menu_shopping_list_total){
// Toast.makeText(Shopping_list_activity.this, getPriceOfDisplayedItems() + " total", Toast.LENGTH_SHORT).show();
// }
return super.onOptionsItemSelected(item);
}
private void updateMenuTitles() {
MenuItem menuItem = menu.findItem(R.id.menu_shopping_list_total);
if (getPriceOfDisplayedItems() > 0) {
menuItem.setTitle(String.valueOf(getPriceOfDisplayedItems()));
} else {
menuItem.setTitle("Total: 0.00");
}
}
The getPriceOfDisplayedItems() displays the correct price.
And the XML file :
<?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">
<item
android:id="#+id/menu_shopping_list_total"
android:title="#string/total"
app:showAsAction="always" />
</menu>
Can anyone help me with this problem?
I think onCreate method is called before onCreateOptions menu. That's why this.menu is null. Try moving invocation of updateMenuTitles to onCreateOptionsMenu.
You should add menu_shopping_list_saveList item in your 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">
<item
android:id="#+id/menu_shopping_list_total"
android:title="#string/total"
app:showAsAction="always" />
<item
android:id="#+id/menu_shopping_list_saveList"
android:title="#string/total"
app:showAsAction="always" />
</menu>
I am trying to have a search action on my action bar. I have set an icon and have showAsAction set to always but it is still always displayed in the overflow menu. How can I make it display on the action bar itself? Thanks!
Activity
public class MainActivity extends ActionBarActivity {
#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.
setTitle("Add");
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
Toast.makeText(getApplicationContext(), "Settings",
Toast.LENGTH_LONG).show();
return true;
}
if (id == R.id.action_search) {
Toast.makeText(getApplicationContext(), "Search",
Toast.LENGTH_LONG).show();
return true;
}
return super.onOptionsItemSelected(item);
}
}
Menu XML file
<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.testtabs.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:actionViewClass="android.support.v7.widget.SearchView"
android:icon="#drawable/ic_search"
android:showAsAction="always"
android:title="#string/title_search"/>
</menu>
Either remove
android:actionViewClass="android.support.v7.widget.SearchView"
or delete your case statement for action_search in onOptionsItemSelected. Doing either of those will display the icon.
If you want to use SearchView the callback is handled differently than onOptionsItemSelected.
Documentation here: http://developer.android.com/guide/topics/ui/actionbar.html#ActionView
Just change app:showAsAction instead of android:showAsAction
<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.testtabs.MainActivity" >
<item
android:id="#+id/action_settings"
android:orderInCategory="100"`enter code here`
android:title="#string/action_settings"
app:showAsAction="never"/>
<item
android:id="#+id/action_search"
android:actionViewClass="android.support.v7.widget.SearchView"
android:icon="#drawable/ic_search"
app:showAsAction="always"
android:title="#string/title_search"/>
</menu>
