android-actionbar

After I updated the Android SDK to version 5.0 the getActionBar() method started to return null causing my app to crash on launch. I am clueless to what's causing this and any existing Stackoverflow threads didn't help. Here is my manifest: <application android:name="App" android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/ActionBarTheme" > styles.xml: <style name="AppBaseTheme" parent="Theme.AppCompat.Light"></style> <!-- Application theme. --> <style name="AppTheme" parent="AppBaseTheme"></style> <style name="ListItemPadding"

I want to preserve the text selection in a webView while preventing any contextual menu of the actioMode from being shown. Neither the new floating one nor the old actionBar, just the selection handles and of course the selection behaviour. Hooking to the actionModeCallback in startActionMode allows me to clear all items in the menu in the callback onCreateActionMode. This works fine on android 6, since an empty floating menu won't show at all, and the actionMode text selection behaviour is preserved. Unfortunately on android < 6 this leaves an empty actionBar shown, how can I completely

I am creating an actionbar with custom looking buttons that I put in the icon section of menu.xml. The problem is that, when I press them, I see both the selected version of the image of the button and the blue background of the holo theme. This is my menu.xml: <menu xmlns:android="http://schemas.android.com/apk/res/android" > <item android:id="@+id/current_position" android:icon="@drawable/ab_location_layer" android:menuCategory="container" android:showAsAction="ifRoom" android:title="Current position"> </item> </menu> The ab_location_layer is this: <selector xmlns:android="http://schemas

I have imported an Android sample project called HorizontalPaging in Android Studio and it works fine when I run it. But when I copied the code into my code, I get a NULL pointer exception in getActionBar() . I have been reading about these problems the whole day but can't get it working. Tried copying the entire code from the sample's MainActivity into my project but no improvements so I am guessing that the problem is in some other file like manifest,styles,etc. MainActivity.java copied from the sample project import android.app.ActionBar; import android.app.FragmentTransaction; import

The method getSupportActionBar() returns null when i invoke it through a Test Case based in Roboelectric and JUnit. This is my simple test case: package com.mobile.test; import static org.hamcrest.CoreMatchers.equalTo; import static org.junit.Assert.assertEquals; import static org.junit.Assert.assertThat; import org.junit.Test; import org.junit.runner.RunWith; import org.robolectric.Robolectric; import org.robolectric.RobolectricTestRunner; import android.app.Activity; import android.content.Intent; import com.mobile.android.core.R; import com.mobile.android.core.activity.MainActivity; import

I am developing an Android application that employs a standard ActionBar. on a certain screen i have a Filter icon that is conditionally required, depending on characteristics of the data being displayed, e.g. some data is filterable Others not. i cannot find any methods on actionbar that look likely candidates for programmaticaly hiding an actionbar action icon. how can i enable/disable an actionbar action icon? Or how can i hide/unhide an actionbar action icon? Have a look at this, it shows how to change menu items at runtime. http://developer.android.com/guide/topics/ui/menus.html

I'm using the action bar with search bar too, and I need to use the ActionBar ico like a Back button: But I'm using the navigation drawer too... How can I dismiss/hide/disable the Navigation Drawer menu to use the back button? My ActionBar code: @Override public boolean onCreateOptionsMenu(Menu menu){ MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.main, menu); this.getSupportActionBar().setDisplayShowCustomEnabled(true); this.getSupportActionBar().setDisplayShowTitleEnabled(false); this.getSupportActionBar().setDisplayHomeAsUpEnabled(true); this.getSupportActionBar()
