android4.4增加动态显示隐藏statusbar和禁止statusbar下拉功能

首先还是在设置->显示里加上图形界面

修改packages/apps/Settings/res/xml/display\_settings.xml

增加

修改packages/apps/Settings/res/values/strings.xml增加

<string name="hide_statusbar_title">Hide StatusBar</string>
        <string name="prohibit_statusbar_title">Prohibit statusbar drop-down</string>

修改packages/apps/Settings/src/com/android/settings/DisplaySettings.java增加

private static final String KEY_STATUSBAR_BAR_DROP = "drop_statusbar";
        private static final String KEY_STATUSBAR_BAR_HIDE = "hide_statusbar";
        public static String ACTION_SHOW_STATUS_BAR = "gzys.hclydao.action.show_status_bar";
        public static String ACTION_HIDE_STATUS_BAR = "gzys.hclydao.action.hide_status_bar";

private CheckBoxPreference mDropSta; //add by hclydao
        private CheckBoxPreference mHideSta; //add by hclydao

增加初始化

mDropSta = (CheckBoxPreference) findPreference(KEY_STATUSBAR_BAR_DROP);
    		mDropSta.setPersistent(false);
    		mHideSta = (CheckBoxPreference) findPreference(KEY_STATUSBAR_BAR_HIDE);
    		mHideSta.setPersistent(false);

在onCreate最后

navcheck = Settings.Global.getInt(resolver, Settings.Global.DROP_STATUSBAR,0);
    		if(navcheck == 1)
    			mDropSta.setChecked(true);
    		navcheck = Settings.Global.getInt(resolver, Settings.Global.HIDE_STATUSBAR,0);
    		if(navcheck == 1)
    			mHideSta.setChecked(true);

基于上篇隐藏Navigationbar已经定义了navcheck

在onPreferenceTreeClick中增加判断

else if(preference == mDropSta) { //add by hclydao
    			boolean isCheck = mDropSta.isChecked();
    			Settings.Global.putInt(getContentResolver(), Settings.Global.DROP_STATUSBAR, isCheck ? 1 : 0);
    		} else if(preference == mHideSta) { //add by hclydao
    			boolean isCheck = mHideSta.isChecked();
    			Settings.Global.putInt(getContentResolver(), Settings.Global.HIDE_STATUSBAR, isCheck ? 1 : 0);
    			Intent mychange;
    			if(isCheck) {
    		            mychange = new Intent(ACTION_HIDE_STATUS_BAR);
    			} else {
    		            mychange = new Intent(ACTION_SHOW_STATUS_BAR);
    			}
    			getActivity().sendBroadcast(mychange);
    		}

图形界面部分就修改完了，接着完善功能

修改frameworks/base/core/java/android/provider/Settings.java增加

public static final String HIDE_STATUSBAR = "hide_statusbar";
           public static final String DROP_STATUSBAR = "drop_statusbar";

保存全局设置

禁止statusbar下拉的完善

修改frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/PanelBar.java增加

import android.provider.Settings;
    import android.content.ContentResolver;

private Context mContext;//add by hclydao

在public PanelBar(Context context, AttributeSet attrs) \{最后增加

mContext = context;

修改public PanelView selectPanelForTouch函数

public PanelView selectPanelForTouch(MotionEvent touch) {
            final int N = mPanels.size();
    		int dropstatus = Settings.Global.getInt(mContext.getContentResolver(), Settings.Global.DROP_STATUSBAR,0);
    		if(dropstatus == 1) //add by hclydao
    			return null;//modify by hclydao
    		else
            	return mPanels.get((int)(N * touch.getX() / getMeasuredWidth()));
        }

修改frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBarView.java增加

import android.provider.Settings;
    import android.content.ContentResolver;

private Context mContext;//add by hclydao

修改函数public PanelView selectPanelForTouch最后的return

int dropstatus = Settings.Global.getInt(mContext.getContentResolver(), Settings.Global.DROP_STATUSBAR,0);
    		if(dropstatus == 1) //add by hclydao
    			return null;//modify by hclydao
    		else
            	return showSettings ? mSettingsPanel : mNotificationPanel;

隐藏statusbar功能完善

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

增加

public static String ACTION_SHOW_STATUS_BAR = "gzys.hclydao.action.show_status_bar";
    	public static String ACTION_HIDE_STATUS_BAR = "gzys.hclydao.action.hide_status_bar";

在addStatusBarWindow函数最后加上

//add by hclydao
            IntentFilter filter = new IntentFilter();
            filter.addAction(ACTION_HIDE_NAV_BAR);
            filter.addAction(ACTION_SHOW_NAV_BAR);
            filter.addAction(ACTION_SHOW_STATUS_BAR);
            filter.addAction(ACTION_HIDE_STATUS_BAR);
            mContext.registerReceiver(mHideNavBarReceiver, filter);
    		int navcheck = Settings.Global.getInt(mContext.getContentResolver(), Settings.Global.HIDE_STATUSBAR,0);
    		if(navcheck != 0)
    			showStatusBar(false);

在destroy函数最后加上

mContext.unregisterReceiver(mHideNavBarReceiver);//hclydao

文件最后增加

//add by hclydao
        public void showStatusBar(boolean isshow) {
    		if(mStatusBarWindow != null) {/*
    		    WindowManager.LayoutParams lp = (WindowManager.LayoutParams) mStatusBarWindow.getLayoutParams();
    			if(isshow)
    			    lp.height = getStatusBarHeight();
    			else
    				lp.height = 0;
    		    mWindowManager.updateViewLayout(mStatusBarWindow, lp);*/
    			mStatusBarWindow.setVisibility(isshow ? View.VISIBLE : View.GONE);
    		}
    	}
    
        BroadcastReceiver mHideNavBarReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
    			if(intent.getAction().equals(ACTION_HIDE_NAV_BAR)) {
    				//hideNavBar();
    			} else if(intent.getAction().equals(ACTION_SHOW_NAV_BAR)) {
    				//showNavBar();
    			} else if(intent.getAction().equals(ACTION_SHOW_STATUS_BAR)) {
    				showStatusBar(true);
    			} else if(intent.getAction().equals(ACTION_HIDE_STATUS_BAR)) {
    				showStatusBar(false);
    			}
            }
        };

修改frameworks/base/policy/src/com/android/internal/policy/impl/PhoneWindowManager.java增加

public static String ACTION_SHOW_STATUS_BAR = "gzys.hclydao.action.show_status_bar";
    	public static String ACTION_HIDE_STATUS_BAR = "gzys.hclydao.action.hide_status_bar";

int oStatusBarHeight;//add by hclydao

基于前一篇隐藏Navigationbar中在         context.registerReceiver(mHideNavBarReceiver, filter);前增加

filter.addAction(ACTION_SHOW_STATUS_BAR);
            filter.addAction(ACTION_HIDE_STATUS_BAR);

在             hideNavBar();下增加

navcheck = Settings.Global.getInt(mContext.getContentResolver(), Settings.Global.HIDE_STATUSBAR,0);
    		if(navcheck != 0)
    			showStatusBar(false);

在 mHideNavBarReceiver中增加判断

} else if(intent.getAction().equals(ACTION_SHOW_STATUS_BAR)) {
    				showStatusBar(true);
    			} else if(intent.getAction().equals(ACTION_HIDE_STATUS_BAR)) {
    				showStatusBar(false);

增加showStatusBar函数

public void showStatusBar(boolean isshow) {
    		if(isshow) {
    			mStatusBarHeight = oStatusBarHeight;
    		} else {
    			if(mStatusBarHeight == 0)
    				return;
    			oStatusBarHeight = mStatusBarHeight;
    			mStatusBarHeight = 0;
    		}
    		updateRotation(false);
    	}

效果图如下:
