Google从KK开始增加了状态栏透明以及全屏界面有通知可以下拉状态栏的设计,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,这样对一些工程测试app可能会造成一定的影响,但是以google默认的设计,应用端无法修改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,如果贵司的代码还没有这部分逻辑,请参考如下:
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. 請在修改完framework后,將測試app用setSystemUiVisibility的API加上SYSTEM_UI_FLAG_IMMERSIVE_GESTURE_ISOLATED的flag
