android-actionbar

问题 As the title suggests, I want to put some text in the action bar. Firstly, here's a mockup (in Paint!) of what I'm imagining: I'm really struggling with this. In my activity I put: @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.main_screen, menu); return true; } And in the menu folder I put main_screen.xml: <?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android" > <item android:id="@+id/user_level"

问题 I've tried setting the action bar I custom-made for my application to be transparent. However instead of being completely transparent, it leaves a weird elevation shadow: http://puu.sh/rdYyb/04ce0147f6.jpg The XML for the bar: <android.support.design.widget.AppBarLayout android:id="@+id/appbarlayout" android:layout_width="match_parent" android:layout_height="wrap_content" android:theme="@style/AppTheme.AppBarOverlay"> <android.support.v7.widget.Toolbar android:id="@+id/toolbar" android:layout

问题 I have a menu item as explained in How do I add a button as a menu item?. When I use an icon, I can click on the icon fine. But when I use an actionLayout , I am getting no response on click. Here is the button the actionLayout points to: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" > <Button android:id="@+id/my_btn" android:layout_width="wrap_content"

In order to get the data defined in them (and not sended by the parent Activity) I am wrote the following code: MyFragment frag = (MyFragment) mSectionsPagerAdapter.getActiveFragment(mViewPager,1

问题 I have inflated my action bar and created items. They show in the overflow but when I try to add code and make them show with yourapp:showAsAction="ifRoom", it gives me errors. Here is my main.xml: <menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:yourapp="http://schemas.android.com/apk/res-auto" > <item android:id="@+id/action_settings" android:orderInCategory="100" android:showAsAction="never" android:title="@string/action_settings"/> <item android:id="@+id/home"

问题 I'd like to have a layout where screen real estate is important on smaller screens, but I'd like users to be able to swipe between exactly two tabs. On these smaller screened devices, I don't want to waste an entire row with a scrollable tab widget like this: but fixed tabs offer no indication to users that they can swipe: Users will typically need to view both tabs to complete the task. Is there any way presently to embed tabs with support for "swipe to switch tabs" inside the main action

问题 I want to put a switch button into MenuItem with showAsAction="never" but it's not working.
