音量按键处理流程

Android系统定义了音量volume_uo和volume_down的值KeyEevent,

frameworks/base/core/java/android/view/KeyEvent.java

1. /** Key code constant: Volume Up key.
   
2.      * Adjusts the speaker volume up. */
   
3.     public static final int KEYCODE_VOLUME_UP       = 24;                                                                                         
   
4.     /** Key code constant: Volume Down key.
   
5.      * Adjusts the speaker volume down. */
   
6.     public static final int KEYCODE_VOLUME_DOWN     = 25;

复制代码

在frameworks/base/packages/SystemUI/res/layout/文件下添加volume_add2的xml

1. <?xml version="1.0" encoding="utf-8"?>
   
2. <com.android.systemui.statusbar.policy.KeyButtonView
   
3.         xmlns:android="http://schemas.android.com/apk/res/android"
   
4.         xmlns:systemui="http://schemas.android.com/apk/res-auto"
   
5.         android:id="@+id/volume_add2"
   
6.         android:layout_width="@dimen/navigation_key_width"
   
7.         android:layout_height="match_parent"
   
8.         android:layout_weight="0"
   
9.         systemui:keyCode="24"//这里就是对应按钮的KEYCODE_VOLUME_UP  表示音量+
   
10.         android:scaleType="center"
    
11.         android:contentDescription="@string/accessibility_home"
    
12.         android:paddingStart="@dimen/navigation_key_padding"
    
13.         android:paddingEnd="@dimen/navigation_key_padding

复制代码

音量加按键图像文件路径：
frameworks/base/packages/SystemUI/res/drawable/文件夹下添加


ic_sysbar_volume_add2_button.xml

1. <vector xmlns:android="http://schemas.android.com/apk/res/android"
   
2.         android:width="24dp"
   
3.         android:height="24dp"
   
4.         android:viewportWidth="24.0"
   
5.         android:viewportHeight="24.0">
   
6.     <path
   
7.             android:fillColor="?attr/singleToneColor"
   
8.             android:pathData="M3,9v6h4l5,5L12,4L7,9L3,9zM16.5,12c0,-1.77 -1.02,-3.29 -2.5,-4.03v8.05c1.48,-0.73 2.5,-2.25 2.5,-4.02zM14,3.23v2.06c2.89,0.86 5,3.54 5,6.71s-2.11,5.85 -5,6.71v2.06c4.01,-0.91 7,-4.49 7,-8.77s-2.99,-7.86 -7,-8.77z"/>

最后在NavigationBarFragment.java添加新的按钮属性 ，路径是frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/
