Android11在导航栏中添加软关机按钮
一、配置文件准备：
1.准备一张power按钮的图片：
Android11和以往又有不同，不再是用png格式的图片，用的是矢量图。可以阿里巴巴矢量图库里面招图片，再用as转成xml文件，内容如下：
packages/SystemUI/res/drawable/ic_sysbar_power.xml

3.修改config文件：
diff --git a/packages/SystemUI/res/values-sw400dp/config.xml b/packages/SystemUI/res/values-sw400dp/config.xml old mode 100644 new mode 100755 index de33fb5..1a70147 --- a/packages/SystemUI/res/values-sw400dp/config.xml +++ b/packages/SystemUI/res/values-sw400dp/config.xml @@ -22,6 +22,6 @@ <resources> <!-- Nav bar button default ordering/layout --> - <string name="config_navBarLayout" translatable="false">left;volume_sub,back,home,recent,volume_add,screenshot;right</string> + <string name="config_navBarLayout" translatable="false">left;volume_sub,back,home,recent,volume_add,screenshot,power;right</string> </resources> diff --git a/packages/SystemUI/res/values-sw600dp/config.xml b/packages/SystemUI/res/values-sw600dp/config.xml old mode 100644 new mode 100755 index 3c0ee9f..a434084 --- a/packages/SystemUI/res/values-sw600dp/config.xml +++ b/packages/SystemUI/res/values-sw600dp/config.xml @@ -27,7 +27,7 @@ <integer name="quick_settings_user_time_settings_tile_span">1</integer> <!-- Nav bar button default ordering/layout --> - <string name="config_navBarLayout" translatable="false">left;volume_sub,back,home,recent,volume_add,screenshot;right</string> + <string name="config_navBarLayout" translatable="false">left;volume_sub,back,home,recent,volume_add,screenshot,power;right</string> <!-- Animation duration when using long press on recents to dock --> <integer name="long_press_dock_anim_duration">290</integer> diff --git a/packages/SystemUI/res/values-sw720dp/config.xml b/packages/SystemUI/res/values-sw720dp/config.xml old mode 100644 new mode 100755 index b850aef..b28e749 --- a/packages/SystemUI/res/values-sw720dp/config.xml +++ b/packages/SystemUI/res/values-sw720dp/config.xml @@ -27,6 +27,6 @@ <integer name="keyguard_max_notification_count">5</integer> <!-- Nav bar button default ordering/layout --> - <string name="config_navBarLayout" translatable="false">left;volume_sub,back,home,recent,volume_add,screenshot;right</string> + <string name="config_navBarLayout" translatable="false">left;volume_sub,back,home,recent,volume_add,screenshot,power;right</string> </resources> diff --git a/packages/SystemUI/res/values-sw900dp/config.xml b/packages/SystemUI/res/values-sw900dp/config.xml old mode 100644 new mode 100755 index f957d6e..1adb097 --- a/packages/SystemUI/res/values-sw900dp/config.xml +++ b/packages/SystemUI/res/values-sw900dp/config.xml @@ -19,6 +19,6 @@ <resources> <!-- Nav bar button default ordering/layout --> - <string name="config_navBarLayout" translatable="false">left;volume_sub,back,home,recent,volume_add,screenshot;right</string> + <string name="config_navBarLayout" translatable="false">left;volume_sub,back,home,recent,volume_add,screenshot,power;right</string> </resources> diff --git a/packages/SystemUI/res/values/config.xml b/packages/SystemUI/res/values/config.xml old mode 100644 new mode 100755 index eedfe31..9c659ae --- a/packages/SystemUI/res/values/config.xml +++ b/packages/SystemUI/res/values/config.xml @@ -341,7 +341,7 @@ </string-array> <!-- Nav bar button default ordering/layout --> - <string name="config_navBarLayout" translatable="false">left[.5W];volume_sub,back,home,recent,volume_add,screenshot;right[.5W]</string> + <string name="config_navBarLayout" translatable="false">left[.5W];volume_sub,back,home,recent,volume_add,screenshot,power;right[.5W]</string> <string name="config_navBarLayoutQuickstep" translatable="false">back[1.7WC];home;contextual[1.7WC]</string> <string name="config_navBarLayoutHandle" translatable="false">back[40AC];home_handle;ime_switcher[40AC]</string>
二、java代码实现
1.添加按钮：
diff --git a/packages/SystemUI/src/com/android/systemui/statusbar/phone/NavigationBarInflaterView.java b/packages/SystemUI/src/com/android/systemui/statusbar/phone/NavigationBarInflaterView.java old mode 100644 new mode 100755 index 7014673..94dd1c1 --- a/packages/SystemUI/src/com/android/systemui/statusbar/phone/NavigationBarInflaterView.java +++ b/packages/SystemUI/src/com/android/systemui/statusbar/phone/NavigationBarInflaterView.java @@ -67,6 +67,7 @@ public class NavigationBarInflaterView extends FrameLayout public static final String SCREENSHOT = "screenshot"; public static final String VOLUME_ADD = "volume_add"; public static final String VOLUME_SUB = "volume_sub"; + public static final String POWER = "power"; public static final String GRAVITY_SEPARATOR = ";"; public static final String BUTTON_SEPARATOR = ","; @@ -405,6 +406,8 @@ public class NavigationBarInflaterView extends FrameLayout v = inflater.inflate(R.layout.volume_add, parent, false); } else if (VOLUME_SUB.equals(button)) { v = inflater.inflate(R.layout.volume_sub, parent, false); + } else if (POWER.equals(button)) { + v = inflater.inflate(R.layout.power, parent, false); } else if (button.startsWith(KEY)) { String uri = extractImage(button); int code = extractKeycode(button); diff --git a/packages/SystemUI/src/com/android/systemui/statusbar/phone/NavigationBarView.java b/packages/SystemUI/src/com/android/systemui/statusbar/phone/NavigationBarView.java old mode 100644 new mode 100755 index 6b4a157..1679e89 --- a/packages/SystemUI/src/com/android/systemui/statusbar/phone/NavigationBarView.java +++ b/packages/SystemUI/src/com/android/systemui/statusbar/phone/NavigationBarView.java @@ -125,6 +125,7 @@ public class NavigationBarView extends FrameLayout implements private KeyButtonDrawable mVolumeAddIcon; private KeyButtonDrawable mVolumeSubIcon; private KeyButtonDrawable mScreenshotIcon; + private KeyButtonDrawable mPowerIcon; private EdgeBackGestureHandler mEdgeBackGestureHandler; private final DeadZone mDeadZone; @@ -335,6 +336,7 @@ public class NavigationBarView extends FrameLayout implements mButtonDispatchers.put(R.id.screenshot, new ButtonDispatcher(R.id.screenshot)); mButtonDispatchers.put(R.id.volume_add, new ButtonDispatcher(R.id.volume_add)); mButtonDispatchers.put(R.id.volume_sub, new ButtonDispatcher(R.id.volume_sub)); + mButtonDispatchers.put(R.id.power, new ButtonDispatcher(R.id.power)); mDeadZone = new DeadZone(this); mNavColorSampleMargin = getResources() @@ -491,6 +493,10 @@ public class NavigationBarView extends FrameLayout implements return mButtonDispatchers.get(R.id.volume_sub); } + public ButtonDispatcher getPowerButton() { + return mButtonDispatchers.get(R.id.power); + } + public RotationContextButton getRotateSuggestionButton() { return (RotationContextButton) mButtonDispatchers.get(R.id.rotate_suggestion); } @@ -539,6 +545,7 @@ public class NavigationBarView extends FrameLayout implements mVolumeAddIcon = getDrawable(R.drawable.ic_sysbar_volume_add_button); mVolumeSubIcon = getDrawable(R.drawable.ic_sysbar_volume_sub_button); mScreenshotIcon = getDrawable(R.drawable.ic_sysbar_capture_button); + mPowerIcon = getDrawable(R.drawable.ic_sysbar_power); } public KeyButtonDrawable getBackDrawable() { @@ -695,6 +702,7 @@ public class NavigationBarView extends FrameLayout implements getVolumeAddButton().setImageDrawable(mVolumeAddIcon); getVolumeSubButton().setImageDrawable(mVolumeSubIcon); getScreenshotButton().setImageDrawable(mScreenshotIcon); + getPowerButton().setImageDrawable(mPowerIcon); updateRecentsIcon();
2.点击按键时动作处理：
diff --git a/packages/SystemUI/src/com/android/systemui/statusbar/phone/NavigationBarFragment.java b/packages/SystemUI/src/com/ android/systemui/statusbar/phone/NavigationBarFragment.java old mode 100644 new mode 100755 index 95a9eda..3ef4c3a --- a/packages/SystemUI/src/com/android/systemui/statusbar/phone/NavigationBarFragment.java +++ b/packages/SystemUI/src/com/android/systemui/statusbar/phone/NavigationBarFragment.java @@ -1049,6 +1049,24 @@ public class NavigationBarFragment extends LifecycleFragment implements Callback volumeAddButton.setVisibility(View.GONE); volumeSubButton.setVisibility(View.GONE); } + + ButtonDispatcher powerButton = mNavigationBarView.getPowerButton(); + powerButton.setOnClickListener(this:: powerClick); + powerButton.setOnTouchListener(this:: powerTouch); + + } + + private boolean powerTouch(View v, MotionEvent event) { + if (event.getAction() == MotionEvent.ACTION_UP) { + Intent intent=new Intent("com.xzy.systemui.poweroff"); + getContext().sendBroadcast(intent); + } + return false; + } + + private void powerClick(View v) { + Intent intent=new Intent("com.xzy.systemui.poweroff"); + getContext().sendBroadcast(intent); } private boolean onHomeTouch(View v, MotionEvent event) {
点击按钮，发出关机消息的广播。
3.关机弹框的实现：
注册广播，接受到广播后弹出关机重启选择的弹框
diff --git a/services/core/java/com/android/server/policy/PhoneWindowManager.java b/services/core/java/com/android/server/policy/PhoneWindowManager.java index d966f36..4671c2f 100755 --- a/services/core/java/com/android/server/policy/PhoneWindowManager.java +++ b/services/core/java/com/android/server/policy/PhoneWindowManager.java @@ -2020,6 +2020,7 @@ public class PhoneWindowManager implements WindowManagerPolicy { filter = new IntentFilter(); filter.addAction(Intent.ACTION_DREAMING_STARTED); filter.addAction(Intent.ACTION_DREAMING_STOPPED); + filter.addAction("com.xzy.systemui.poweroff"); context.registerReceiver(mDreamReceiver, filter); // register for multiuser-relevant broadcasts @@ -4494,6 +4495,10 @@ public class PhoneWindowManager implements WindowManagerPolicy { if (mKeyguardDelegate != null) { mKeyguardDelegate.onDreamingStopped(); } + } else if("com.xzy.systemui.poweroff".equals(intent.getAction())) { + + Slog.v(TAG, "wmc...Receive a soft poweroff broadcast."); + showGlobalActionsInternal(); } } };
showGlobalActionsInternal这个方法是调出关机弹框的。
但此时发现弹框是这样的：
经过了解，发现Android 原生的关机界面有两种，一种是LegacyGlobalActions中的dialog,另一种是SystemUI中的GlobalActionsDialog(以上图片)。
继续看弹框的代码流程：
void showGlobalActionsInternal() { if (mGlobalActions == null) { mGlobalActions = new GlobalActions(mContext, mWindowManagerFuncs); } final boolean keyguardShowing = isKeyguardShowingAndNotOccluded(); mGlobalActions.showDialog(keyguardShowing, isDeviceProvisioned()); // since it took two seconds of long press to bring this up, // poke the wake lock so they have some time to see the dialog. mPowerManager.userActivity(SystemClock.uptimeMillis(), false); }
showGlobalActionsInternal->mGlobalActions.showDialog
services/core/java/com/android/server/policy/GlobalActions.java
public void showDialog(boolean keyguardShowing, boolean deviceProvisioned) { if (DEBUG) Slog.d(TAG, "showDialog " + keyguardShowing + " " + deviceProvisioned); if (mGlobalActionsProvider != null && mGlobalActionsProvider.isGlobalActionsDisabled()) { return; } mKeyguardShowing = keyguardShowing; mDeviceProvisioned = deviceProvisioned; mShowing = true; if (mGlobalActionsAvailable && !"box".equals(SystemProperties.get("ro.target.product","unkonw"))) { mHandler.postDelayed(mShowTimeout, 5000); mGlobalActionsProvider.showGlobalActions(); } else { // SysUI isn't alive, show legacy menu. ensureLegacyCreated(); mLegacyGlobalActions.showDialog(mKeyguardShowing, mDeviceProvisioned); } }
在这里就能找到原因了，编译的系统ro.target.product不是box的，所以流程走的是mGlobalActionsProvider.showGlobalActions()，即前面调出的图片。
这样修改一下即可：
index ecd1eab..31250a9 100755 --- a/services/core/java/com/android/server/policy/GlobalActions.java +++ b/services/core/java/com/android/server/policy/GlobalActions.java @@ -65,7 +65,7 @@ class GlobalActions implements GlobalActionsProvider.GlobalActionsListener { mKeyguardShowing = keyguardShowing; mDeviceProvisioned = deviceProvisioned; mShowing = true; - if (mGlobalActionsAvailable && !"box".equals(SystemProperties.get("ro.target.product","unkonw"))) { + if (mGlobalActionsAvailable && !"tablet".equals(SystemProperties.get("ro.target.product","unkonw"))) { mHandler.postDelayed(mShowTimeout, 5000); mGlobalActionsProvider.showGlobalActions(); } else {
此时调用的是mLegacyGlobalActions.showDialog，弹框图片：
