android 下拉状态栏(SystemUI)常见修改记录

下拉状态栏:

1.下拉状态栏的亮度条：

frameworks/base/packages/SystemUI/src/com/android/systemui/qs/QSPanel.java

mBrightnessView

对应布局文件：quick_settings_brightness_dialog.xml

2.滑动亮度条后过渡到桌面的亮度条

frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBar.java

protected void inflateStatusBarWindow(Context context) { 
        mStatusBarWindow = (StatusBarWindowView) View.inflate(context, 
                R.layout.super_status_bar, null); 
    }

mStatusBarWindow

对应布局文件：super_status_bar.xml

布局文件中对应项：

3.亮度条中的滑动条样式修改

frameworks/base/packages/SystemUI/src/com/android/systemui/settings/ToggleSlider.java

布局文件：status_bar_toggle_slider.xml

4.下拉状态栏的图标块

有两处

/frameworks/base/packages/SystemUI/src/com/android/systemui/qs/tiles/***Tile.java

对应的Vector矢量图文件命名为ic_qs_xxx.xml

AirplaneModeTile:飞行模式，默认有动画的。用图片替换要把动画在代码中注释掉。

BatteryTile:电池。用BatteryMeterDrawable自定义view画出来的。

BluetoothTile:蓝牙

CastTile:投射

CellularTile:移动数据网络，无sim卡

ColorInversionTile:反色

DataSaverTile:流量节省程序

DataUsageDetailView:默认没显示，数据使用细节

DndTile:勿扰donot disturb

FlashlightTile:手电筒

HotspotTile:热点

IntentTile:默认没显示，不知道长啥样

LocationTile:位置信息

RotationLockTile:自动旋转，纵向

ScreenShotTile:截图

UserDetailItemView:默认没显示，不知道长啥样

UserDetailView:默认没显示，不知道长啥样

UserTile:默认没显示，不知道长啥样

WifiTile:Wlan

WorkModeTile:默认没显示，不知道长啥样

还有MTK的

/frameworks/base/packages/SystemUI/src/com/mediatek/systemui/qs/tiles/***Tile.java

HotKnotTile

ApnSettingsTile

DualSimSettingsTile

MobileDataTile

QsIconWrapper

SimDataConnectionTile

5.增删下拉状态栏的图标块

frameworks/base/packages/SystemUI/res/values/config.xml中修改

wifi,cell,battery,dnd,flashlight,rotation,bt,airplane,location,hotknot,screenshot

6.WLAN图标块点击后信号强度

frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/policy/AccessPointControllerImpl.java

    private static final int[] ICONS = { 
        R.drawable.ic_qs_wifi_full_0, 
        R.drawable.ic_qs_wifi_full_1, 
        R.drawable.ic_qs_wifi_full_2, 
        R.drawable.ic_qs_wifi_full_3, 
        R.drawable.ic_qs_wifi_full_4, 
    };

7.修改手机信号强度图

frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/policy/TelephonyIcons.java

    static final int[][] QS_TELEPHONY_SIGNAL_STRENGTH = { 
        { R.drawable.ic_qs_signal_0, 
          R.drawable.ic_qs_signal_1, 
          R.drawable.ic_qs_signal_2, 
          R.drawable.ic_qs_signal_3, 
          R.drawable.ic_qs_signal_4 }, 
        { R.drawable.ic_qs_signal_full_0, 
          R.drawable.ic_qs_signal_full_1, 
          R.drawable.ic_qs_signal_full_2, 
          R.drawable.ic_qs_signal_full_3, 
          R.drawable.ic_qs_signal_full_4 } 
    };

8.单条通知栏ｕｉ修改

修改两个位置：

位置１：

frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/ActivatableNotificationView.java　

protectedvoid onFinishInflate() {}中

修改下面两句

mBackgroundNormal.setCustomBackground

mBackgroundDimmed.setCustomBackground

同时让下面两个方法为空

privatevoid updateOutlineAlpha() {}

publicvoid setFakeShadowIntensity(float shadowIntensity, floatoutlineAlpha, int shadowYEnd,

intoutlineTranslation) {}

位置２：

frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/stack/NotificationStackScrollLayout.java

这个是个ViewGroup，它在onDraw里面还画了次背景。需要干掉这个背景。

让下面这个方法为空。

privatevoid updateBackground() {}

protectedvoid onDraw(Canvas canvas) {}中注销掉下面这句

canvas.drawRect(0,mCurrentBounds.top, getWidth(), mCurrentBounds.bottom,mBackgroundPaint);

修改后效果：

9.多条通知栏的背景修改

frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/NotificationPanelView

默认背景就是当前界面截图加了个黑色透明度。

这个要谨改，因为会影响到按下power键唤醒屏幕时候的锁屏。如果把背景设成黑色，可能power键唤醒屏幕后，多条通知栏的背景是黑的。

10.删除修改显示布局边界，GPU呈现模式分析，Nearby

GPU呈现模式分析，显示布局边界都是packages/apps/Settings中的

在AndroidManifest.xml中可以找到

label对应的string在framework/base/packages/SettingsLib中

icon对应的drawable在packages/apps/Settings中

packages/apps/Settings/src/com/android/settings/qstile/DevelopmentTiles.java

Nearby是谷歌的玩意，修改的话也能修改，就是加判定在TileQueryHelper.java中修改，当然上面的

GPU呈现模式分析，显示布局边界也可以这么修改。只不过不建议用这种方式修改。

删除这三个东西：

frameworks/base/packages/SystemUI/src/com/android/systemui/qs/customize/TileQueryHelper.java

中

    private class QueryTilesTask extends 
            AsyncTask>, Void, Collection> {}
		doInBackground{}中
            List services = pm.queryIntentServicesAsUser( 
                    new Intent(TileService.ACTION_QS_TILE), 0, ActivityManager.getCurrentUser());
这句修改为
			//lqp 
            	//List services = pm.queryIntentServicesAsUser( 
               //     new Intent(TileService.ACTION_QS_TILE), 0, ActivityManager.getCurrentUser()); 
		List services = new ArrayList(); 

11.为原生android下拉状态栏新增自动调节亮度开关

alps/device/mediatek/mt6735/bird.mk

alps/frameworks/base/packages/SystemUI/bird/res/layout/ui_icon_qs_brightness_dialog.xml

alps/frameworks/base/packages/SystemUI/bird/res/values-zh-rCN/strings.xml

alps/frameworks/base/packages/SystemUI/bird/res/values/strings.xml

alps/frameworks/base/packages/SystemUI/bird/src/com/bird/systemui/BirdFeatureOption.java

alps/frameworks/base/packages/SystemUI/res/layout/quick_settings_brightness_dialog.xml

alps/frameworks/base/packages/SystemUI/src/com/android/systemui/qs/QSPanel.java

.../base/packages/SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBar.java

alps/packages/apps/Settings/src/com/android/settings/DisplaySettings.java

三个地方需要同步，设置中的显示DisplaySettings.下拉状态栏的图标处QSPanel，点击滑条后的PhoneStatusBar。

如何同步？　使用观察者模式。

在Switch进行操作后需要变更Settings.System.SCREEN_BRIGHTNESS_MODE值。在值变化后Switch控件状态需要同步变化。

QSPanel.java中代码：

//liuqipeng add 20170619 BUG #26165 
import android.widget.CompoundButton; 
import android.widget.ToggleButton; 
import android.widget.Switch; 
import android.provider.Settings; 
import android.widget.CompoundButton.OnCheckedChangeListener; 
import android.database.ContentObserver; 
import static android.provider.Settings.System.SCREEN_BRIGHTNESS_MODE; 
import static android.provider.Settings.System.SCREEN_BRIGHTNESS_MODE_AUTOMATIC; 
import static android.provider.Settings.System.SCREEN_BRIGHTNESS_MODE_MANUAL; 
//liuqipeng end 20170619
public QSPanel(Context context, AttributeSet attrs) {
		//liuqipeng add 20170619 BUG #26165 
		if(BirdFeatureOption.BIRD_SHOW_AUTO_BRIGHT_SWITCH){ 
			View mAutoBrightRl=findViewById(R.id.auto_bright_rl); 
			mAutoBrightRl.setVisibility(View.VISIBLE); 
			Switch mAutoBright=(Switch)findViewById(R.id.auto_bright_switch); 
		    int brightnessMode = Settings.System.getInt(context.getContentResolver(), 
		            SCREEN_BRIGHTNESS_MODE, SCREEN_BRIGHTNESS_MODE_MANUAL); 
			mAutoBright.setChecked(brightnessMode != SCREEN_BRIGHTNESS_MODE_MANUAL); 
			mAutoBright.setOnCheckedChangeListener(new OnCheckedChangeListener() { 
			 
				@Override 
				public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 
				    Settings.System.putInt(context.getContentResolver(), SCREEN_BRIGHTNESS_MODE, 
				            isChecked ? SCREEN_BRIGHTNESS_MODE_AUTOMATIC : SCREEN_BRIGHTNESS_MODE_MANUAL); 
				} 
			}); 
			ContentObserver BrightnessMode = new ContentObserver(new Handler()) { 
				@Override 
				public void onChange(boolean selfChange) { 
					super.onChange(selfChange); 
					int brightnessMode = Settings.System.getInt(context.getContentResolver(), 
							SCREEN_BRIGHTNESS_MODE, SCREEN_BRIGHTNESS_MODE_MANUAL); 
					mAutoBright.setChecked(brightnessMode != SCREEN_BRIGHTNESS_MODE_MANUAL); 
				} 
			}; 
			context.getContentResolver().registerContentObserver(Settings.System.getUriFor(Settings.System.SCREEN_BRIGHTNESS_MODE),true, BrightnessMode); 
		} 
｝
		//liuqipeng end 20170619
