android4.4上全屏界面实现禁止状态栏下拉 _状态栏

【android4.4上全屏界面实现禁止状态栏下拉】须知少年凌云志，曾许人间第一流。这篇文章主要讲述android4.4上全屏界面实现禁止状态栏下拉相关的知识，希望能为你提供帮助。
附上我改动的方法：PhoneWindowManager.java里面的改动

Acitvity里面使用例如以下方式：

下面是从MTK Online 上面找到的解决方式。保留备用。 Google从KK開始添加了状态栏透明以及全屏界面有通知能够下拉状态栏的设计，而这个设计出现的隐患是设置了FULL_SCREEN的界面是无法禁止状态栏下拉的。这样对一些project測试app可能会造成一定的影响。可是以google默认的设计，应用端无法改动此设计来满足自己的需求。 MTK 内部已经开发提供新的接口来实现全屏界面禁止下拉状态栏，假设贵司的代码还没有这部分逻辑，请參考例如以下： 1. frameworks\base\core\java\android\view\View.java

public static final int SYSTEM_UI_FLAG_IMMERSIVE_STICKY = 0x00001000; +/** +* @hide +* +* NOTE: Flag for {@link #setSystemUiVisibility(int)}: It help user to disable transient +* status bar triggered by gesture +*/ +public static final int SYSTEM_UI_FLAG_IMMERSIVE_GESTURE_ISOLATED = 0x00002000;

2. frameworks\base\policy\src\com\android\internal\policy\impl\PhoneWindowManager.java

// monitor for system gestures mSystemGestures = new SystemGesturesPointerEventListener(context, new SystemGesturesPointerEventListener.Callbacks() { @Override public void onSwipeFromTop() { +if (isGestureIsolated()) +return; if (mStatusBar != null) { requestTransientBars(mStatusBar); } } @Override public void onSwipeFromBottom() { +if (isGestureIsolated()) +return; if (mNavigationBar != null & & mNavigationBarOnBottom) { requestTransientBars(mNavigationBar); } } @Override public void onSwipeFromRight() { +if (isGestureIsolated()) +return; if (mNavigationBar != null & & !mNavigationBarOnBottom) { requestTransientBars(mNavigationBar); } } @Override public void onDebug() { // no-op } +private boolean isGestureIsolated() { +WindowState win = mFocusedWindow != null ? mFocusedWindow : mTopFullscreenOpaqueWindowState; +if (win != null & & (win.getSystemUiVisibility() & View.SYSTEM_UI_FLAG_IMMERSIVE_GESTURE_ISOLATED) != 0) +return true; +else +return false; +} });

3. 請在改动完framework后，將测試app用setSystemUiVisibility的API加上SYSTEM_UI_FLAG_IMMERSIVE_GESTURE_ISOLATED的flag
