android-toolbar

问题 I have extended the well-known Google Navigation Drawer Example by adding Toolbar and right-side Drawer in a simple test project at GitHub: How to add a "burger" button to the Toolbar - which would open the right Drawer (currently you can only swipe it with a finger)? The "burger" button for the left Drawer is already there and works well (probably added by ActionBarDrawerToggle?) Here is my current activity_main.xml: <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas

问题 Can anybody help me to find the way to remove the left margin of the navigation drawer icon (mentioned by red rectangle below )? I am using toolbar here. 回答1: This removes the left margin from toolbar. mainToolbar.setContentInsetsAbsolute(0, 0); Or you can set left inset to 0dp in toolbar xml: android:contentInsetLeft="0dp" Other way is to define that padding in the styles.xml: <style name="ToolbarStyle" parent="@style/Widget.AppCompat.Toolbar"> <item name="contentInsetStart">0dp</item> <item

问题 I get this weird margin in my app toolbar between icon and navigation icon in the toolbar (as in the image). I've got no idea about where it comes from and how to remove it. After searching the internet I found this: <android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/toolbar" android:layout_height="wrap_content" android:layout_width="match_parent" android:fitsSystemWindows="true"

问题 Here is a picture of the large padding gap after the menu icon: This occurred after not working on my project for a month (summer school). I just came back to it and noticed this larger than normal gap on the toolbar after I updated Android Studio. I can't find any questions/solutions about this on SO.

This is my activity_main.xml <?xml version="1.0" encoding="utf-8"?> <android.support.v4.widget.DrawerLayout 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" android:id="@+id/drawer_layout" android:layout_width=

问题 I used this example to build a layout with two NavigationViews: http://v4all123.blogspot.de/2016/03/simple-example-of-navigation-view-on.html It works fine. But also in the demo on this site you can see, that the Toolbar isn't 100% in the middle. The left button has more space to the left than the right button to the right border.
