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
/** Key code constant: Volume Up key.
* Adjusts the speaker volume up. */
public static final int KEYCODE_VOLUME_UP = 24;
/** Key code constant: Volume Down key.
* Adjusts the speaker volume down. */
public static final int KEYCODE_VOLUME_DOWN = 25;在frameworks/base/packages/SystemUI/res/layout/文件下添加volume_add2的xml
<?xml version="1.0" encoding="utf-8"?>
<com.android.systemui.statusbar.policy.KeyButtonView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:systemui="http://schemas.android.com/apk/res-auto"
android:id="@+id/volume_add2"
android:layout_width="@dimen/navigation_key_width"
android:layout_height="match_parent"
android:layout_weight="0"
systemui:keyCode="24"//这里就是对应按钮的KEYCODE_VOLUME_UP表示音量+
android:scaleType="center"
android:contentDescription="@string/accessibility_home"
android:paddingStart="@dimen/navigation_key_padding"
android:paddingEnd="@dimen/navigation_key_padding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
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="24dp"
android:height="24dp"
android:viewportWidth="24.0"
