android-toolbar

问题 I am having a hard time with v7 Toolbar. What was once a simple task for ActionBar , now seems overly complex. No matter what style I set, I cannot change either navigation icon (which opens a Drawer) or overflow menu icon (which opens a menu). So I have a Toolbar <android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="wrap_content" android

问题 I've implemented the newest appcompat library and using the Toolbar as action bar. But the problem is I cannot catch the home button / hamburger icon click event. I've tried and looked everything but doesn't seem to find a similar problem. This is my Activity class : protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); toolbar = (Toolbar) findViewById(R.id.toolbar); setSupportActionBar(toolbar); // Set up the drawer.

问题 I am trying to get the navigation drawer to open below the toolbar. <android.support.v4.widget.DrawerLayout 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:id="@+id/drawer_layout" tools:context=".MainActivity"> <RelativeLayout android:layout_width = "match_parent" android:layout_height = "wrap_content"> <include layout="@layout/toolbar" android:id="@+id

问题 I am working on using the newly added Toolbar that was introduced in Lollipop and the AppCompat-v7 library. I followed this guide on setting up the Toolbar I noticed that when you invoke something that will bring up the contextual ActionBar (such as highlighting text for copy/pasting), that it will push the Toolbar down on the page. You can see what I am talking about in the image at the bottom of the page: So, essentially, I set it up like this. I have the Toolbar defined in an xml file that

问题 I'm updating my app with the new Toolbar from the support library v21. My problem is that the toolbar does not cast any shadow if I don't set the "elevation" attribute. Is that the normal behavior or I'm doing something wrong?

问题 On this new project, when setting a toolbar into the main activity java file, it gets the error on "setSupportActionBar(mToolbar)" saying "getSupportActionBar() in AppCompatActivity cannot be applyed to (android.support.v7.widget.Toolbar)" On similar questions, the answers was just to change from "import android.widget.Toolbar" to "import android.support.v7.widget.Toolbar" which is already set. The main activity xml is this: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android

问题 The contextual action mode, when overlayed on top of an android.support.v7.widget.Toolbar, does not appear to filter touches over its entire width, but lets touches "fall through" to (invisible) widgets on the Toolbar. My Toolbar contains a custom widget (one of the declared benefits of Toolbar). I have the contextual action mode styled to overlay the toolbar, and it hides it entirely. However, when I touch where the (now obscured) custom widget was located, the touch passes through to it. I
