How did Google manage to do this? Slide ActionBar in Android application
提问by hwrdprkns
I really want to implement this (the side navigation) in an app of my own, does anyone know how Google managed to do this?
我真的很想在我自己的应用程序中实现这个（侧面导航），有谁知道谷歌是如何做到的？
They seem to have pulled the current window aside and put in a fly-in navigation of their own.
他们似乎已将当前窗口拉到一边，并放入了自己的飞入式导航。

In fact, there's a way to do this. Even without implementing your own ActionBar.
事实上，有一种方法可以做到这一点。即使没有实现你自己的ActionBar.
Just have a look at the hierachyviewer! (Located in the tools directory)
看看hierachyviewer吧！（位于工具目录中）
There's the DecorView, and a LinearLayoutas a child. This LinearLayoutcontains both the ActionBarand the other content. So, you can simply apply some FrameLayout.LayoutParamsto this LinearLayoutand get some space on the left side this way. Then, you can fill this space with your menu-ListView and overlay the other content with a FrameLayout, that, when it's clicked, collapses the menu. So, here's some code:
有DecorView, 和LinearLayout小时候。这LinearLayout包含了ActionBar内容和其他内容。因此，您可以简单FrameLayout.LayoutParams地对此应用一些，LinearLayout并通过这种方式在左侧获得一些空间。然后，您可以使用菜单 ListView 填充此空间，并使用 FrameLayout 覆盖其他内容，即在单击时折叠菜单。所以，这里有一些代码：
First, the class for collapsing / expanding (SlideMenu.java):
首先，用于折叠/展开的类（SlideMenu.java）：

private static boolean menuShown = false;
private static View menu;
private static LinearLayout content;
private static FrameLayout parent;
private static int menuSize;
private static int statusHeight = 0;
private Activity act;
SlideMenu(Activity act) {

((ExtendedViewPager) act.findViewById(R.id.viewpager)).setPagingEnabled(true);
((ExtendedPagerTabStrip) act.findViewById(R.id.viewpager_tabs)).setNavEnabled(true);
menuShown = false;
}
}
Some helping methods (for me, in static Functions.java):
一些帮助方法（对我来说，在静态 Functions.java 中）：
public static int dpToPx(int dp, Context ctx) {
Resources r = ctx.getResources();
return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dp, r.getDisplayMetrics());
}
//originally: http://stackoverflow.com/questions/5418510/disable-the-touch-events-for-all-the-views
//modified for the needs here
public static void enableDisableViewGroup(ViewGroup viewGroup, boolean enabled) {
int childCount = viewGroup.getChildCount();
for (int i = 0; i < childCount; i++) {
View view = viewGroup.getChildAt(i);
if(view.isFocusable())
view.setEnabled(enabled);
if (view instanceof ViewGroup) {
enableDisableViewGroup((ViewGroup) view, enabled);
} else if (view instanceof ListView) {
if(view.isFocusable())
view.setEnabled(enabled);
ListView listView = (ListView) view;
int listChildCount = listView.getChildCount();
for (int j = 0; j < listChildCount; j++) {
if(view.isFocusable())
listView.getChildAt(j).setEnabled(false);
}
}
}
}
Then, the layouts:
然后，布局：
Layout of the menu (res/layout/menu.xml)
菜单布局 (res/layout/menu.xml)
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

</LinearLayout>
<FrameLayout

</LinearLayout>
Layout of the listitems (res/layout/menu_listitem.xml):
列表项的布局（res/layout/menu_listitem.xml）：

android:layout_height="wrap_content"
android:textColor="@color/white"
android:textSize="24dp"
android:layout_marginTop="10dip"
android:layout_marginBottom="10dip" />
</LinearLayout>
How to use it:
如何使用它：
In your onCreate():
在您的onCreate()：
private SlideMenu slidemenu;
@Override
public void onCreate(Bundle savedInstanceState) {
//your onCreate code
slidemenu = new SlideMenu(this);
slidemenu.checkEnabled();
}
In the handler for your ActionBar homebutton:
在 ActionBar 主页按钮的处理程序中：
slidemenu.show();
That's it!
就是这样！
And now, a little screenshot of it in action:
现在，它在行动中的一个小截图：
As far as I know, it is working. If you experience any problems or my explanations are not clear, please contact me!
据我所知，它正在起作用。如果您遇到任何问题或我的解释不清楚，请与我联系！

return super.onInterceptTouchEvent(event);
}

ExtendedPagerTabStrip:
扩展的PagerTabStrip：
package your.cool.app;

import android.content.Context;
import android.support.v4.view.PagerTabStrip;

@Override
public boolean onTouchEvent(MotionEvent event) {

if (this.enabled) {
return super.onInterceptTouchEvent(event);
}
return false;
}
public void setNavEnabled(boolean enabled) {
this.enabled = enabled;
}
}
I use this SlideMenufor an Activity with a ViewPagerwith PagerTabStripfor tabs like Talk, Market etc. You can't disable these Views in an easy way, so the two classes above just extend them to stop the onTouchevent when disabled.
我将此SlideMenu用于ViewPager带有PagerTabStrip标签的活动，例如 Talk、Market 等。您无法以简单的方式禁用这些视图，因此上面的两个类只是扩展它们以onTouch在禁用时停止事件。

There are several attemptsat doing this, however I have yet to find a lib or source code on how to implement it successfully with actionbar accross all api levels. One promising lib is here
有几次尝试这样做，但是我还没有找到关于如何使用跨越所有 api 级别的操作栏成功实现它的库或源代码。一个有前途的库在这里
https://github.com/jfeinstein10/SlidingMenu
https://github.com/jfeinstein10/SlidingMenu
here is a video of the example app.
这是示例应用程序的视频。
here is the Google Playapp link.
这是Google Play应用程序链接。
This does work with ActionbarSherlock. You will have to build the SlidingMenu library with ABS to get it working. Works and looks great!
这确实适用于 ActionbarSherlock。您必须使用 ABS 构建 SlidingMenu 库才能使其正常工作。效果很好，看起来很棒！
回答by bk138
Did a roundup of the original implementationand added XML parsing as well as autodetectionof a possibly present actionbar, so it works with the native as well as a support action bar such as ActionBarSherlock.
对原始实现进行了综述，并添加了 XML 解析以及autodetection可能存在的解析actionbar，因此它适用于本机以及支持操作栏，例如ActionBarSherlock.
The whole thing is now a library project together with an example app and is described over at Sliding Menu for androidThanks to sciroccofor the initial idea and code!
整个事情现在是一个库项目和一个示例应用程序，并在android 的滑动菜单中进行了描述。感谢scirocco提供最初的想法和代码！
回答by Medo
If you are using API level greater that 11 you can use a much simpler approach inspired by the answer given by @Scirocco
如果您使用的 API 级别大于 11，则可以使用更简单的方法，其灵感来自@Scirocco 给出的答案
// get content parent that is basically the whole
// app screen (viewed from hierarchy viewer)
final LinearLayout content =
(LinearLayout) findViewById(android.R.id.content).getParent();
// make new value animator with range from 0 to 1
final ValueAnimator animator = ValueAnimator.ofFloat(0, 1);
// set custom duration
animator.setDuration(500);
// on update is called for every value in the
// given range in time frame defined by the duration
animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
public void onAnimationUpdate(ValueAnimator animation) {
// get the current value
float value = ((Float) (animation.getAnimatedValue())).floatValue();
// translate by that value, minus means translate left
content.setTranslationX(-250 * value);
}
});
// start the animator
animator.start();
// make or inflate custom view for test purposes
Button textView = new Button(this);
textView.setText("TestButton");
// add it to the frame layout that is the parent of the content on position 0
FrameLayout parent = (FrameLayout) content.getParent();
parent.addView(textView, 0);
The idea here is to use ValueAnimatorthat transforms and not just animates the main layout with the Action bar, so you can interact with the inflated view you want to use as a sliding panel.
You should replace the hardcoded values with something that is of use to your app.
这里的想法是使用ValueAnimator转换，而不仅仅是通过操作栏为主要布局设置动画，因此您可以与要用作滑动面板的膨胀视图进行交互。您应该使用对您的应用程序有用的内容替换硬编码值。
I hope this helps :)
我希望这有帮助 ：）

Well currently im working on a project and came across Sliding menu,i googled but gets very disappointed to see that no one has given some piece of code or some hint for how to start making a sliding menu,but every one has given link to some github's projects/libraries to use,I decided to do it myself and finally i have my own Sliding Menu Ready...
嗯，目前我正在做一个项目并遇到了滑动菜单，我用谷歌搜索但很失望地看到没有人给出一些代码或一些关于如何开始制作滑动菜单的提示，但每个人都提供了一些链接github 的项目/库使用，我决定自己做，最后我有我自己的滑动菜单准备好......
I have Spent two days on it
我花了两天时间
1. on making animations of sliding
1.关于制作滑动动画
2. on making it work with all screen resolutions
2. 使其适用于所有屏幕分辨率
Its really easy and simple once you get some idea about Animations, i have read some where,its not sensible to re-invent the Wheel(people who are refering to github source code of sliding menu),but i beleif that you should atleast once try to make your own so you get a idea how it actually works and functions :P
一旦你对动画有了一些了解，它真的很容易和简单，我读过一些地方，重新发明轮子是不明智的（那些参考 github 滑动菜单源代码的人），但我相信你应该至少一次尝试制作自己的，以便您了解它的实际工作原理和功能：P
so this is a picture of how my sliding menu will going to work
所以这是我的滑动菜单将如何工作的图片

I've created my own solution for sliding away the view and revealing a menu underneath, as many other solutions appeared to not work on older Android versions or lacked proper instructions on how to get it to work.
我已经创建了自己的解决方案，用于滑动视图并显示下方的菜单，因为许多其他解决方案似乎无法在较旧的 Android 版本上运行，或者缺乏有关如何使其工作的正确说明。
My solution has the following features:
我的解决方案具有以下特点：
- Provides support for sliding away a view to reveal a menu that lies underneath it
- Both the menu and the view above can be any custom View
- Supported on old Android versions (tested to work at least on Android 2.2)
- Works with PhoneGap / Cordova projects
- 支持滑开视图以显示其下方的菜单
- 上面的菜单和视图都可以是任何自定义视图
- 受旧 Android 版本支持（经测试至少可在 Android 2.2 上运行）
- 适用于 PhoneGap / Cordova 项目
The solution uses a custom layout, called SlidingMenuLayout, that you are expected to add 2 views to. The first view you add is the menu, the second is the main view.
该解决方案使用称为 SlidingMenuLayout 的自定义布局，您需要向其中添加 2 个视图。您添加的第一个视图是菜单，第二个是主视图。
The simplest way to add the layout to your existing project is to override your Activity's setContentView()method:
将布局添加到现有项目的最简单方法是覆盖 Activity 的setContentView()方法：
@Override
public void setContentView(View view) {
SlidingMenuLayout layout = new SlidingMenuLayout(this);
layout.setLayoutParams(new LinearLayout.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT,
0.0F));
layout.addView(new MenuView(this));
layout.addView(view);
super.setContentView(layout);
}
In this example, MenuViewis the view that will actually show the menu. It is up to you to implement this view.
Finally, you can add a button (typically in the top left corner of your main view), that calls openMenu()or closeMenu()on the layout as appropriate.
The code for SlidingMenuLayoutis found on the GitHub project page.
在这个例子中，MenuView是实际显示菜单的视图。实现此视图取决于您。
最后，您可以添加一个按钮（通常在主视图的左上角），根据需要在布局上调用openMenu()或closeMenu()。
的代码SlidingMenuLayout可在 GitHub项目页面上找到。

For those of you who uses the SlidingMenulibrary (https://github.com/jfeinstein10/SlidingMenu) there is a way to Hyman it in and it seems to work! With help of @Scirocco put this in your onCreatefor the activity:
对于那些使用SlidingMenu库 ( https://github.com/jfeinstein10/SlidingMenu) 的人来说，有一种方法可以插入它，而且它似乎有效！在@Scirocco 的帮助下，将其放入您onCreate的活动中：
ViewGroup decorView = (ViewGroup) getWindow().getDecorView();
mSlidingMenu = new SlidingMenu(this);
ViewGroup mainContent = (ViewGroup) decorView.getChildAt(0);
decorView.removeView(mainContent);
mSlidingMenu.setContent(mainContent);
decorView.addView(mSlidingMenu);
mMenu = (LinearLayout) View.inflate(this, R.layout.menuview, null);
mSlidingMenu.setMenu(mMenu);
mSlidingMenu.setTouchModeAbove(SlidingMenu.TOUCHMODE_MARGIN);
mSlidingMenu.setBehindOffsetRes(R.dimen.slidingmenu_offset);
basically what it does is replacing the linearlayoutin decor view with the slidingmenuinstead.
基本上它的作用是用代替替换linearlayout装饰视图slidingmenu。
Notice: Ive only tested it lightly but it seems to work.
注意：我只是对其进行了轻微的测试，但它似乎有效。
