【移動應(yīng)用開發(fā)技術(shù)】Android中怎么禁止?fàn)顟B(tài)欄下拉

Android中怎么禁止?fàn)顟B(tài)欄下拉，很多新手對此不是很清楚，為了幫助大家解決這個難題，下面在下將為大家詳細(xì)講解，有這方面需求的人可以來學(xué)習(xí)下，希望你能有所收獲。1.修改SystemUI路徑：==/frameworks/base/packages/SystemUI//src/com/android/systemui/statusbar/phone/PhoneStatusBar.Java==通過在PhoneStatusBar.java類中注冊一個廣播的方式來實(shí)現(xiàn)狀態(tài)欄的禁用和解除，其核心方法就是調(diào)用了disable()方法。disable()是SystemUI自定義的方法，感興趣的同學(xué)可以去看其具體實(shí)現(xiàn)。下面來看下我們在SystemUI中的具體實(shí)現(xiàn)代碼：@@

context.registerReceiver(mStatusShowHide,

statusFilter);既然顯示隱藏的廣播我們已經(jīng)注冊好了，那么看下我們在APP中的具體調(diào)用吧。@Override

protected

void

onResume()

{

super.onResume();

Intent

i

=

Intent("com.aura.statusbar.SHOW_OR_HIDE");

StatusBarManager.DISABLE_EXPAND);

{

super.onPause();

Intent

i

=

new

Intent("com.aura.statusbar.SHOW_OR_HIDE");

i.putExtra("mode",

StatusBarManager.DISABLE_NONE);

sendBroadcast(i);

}在Activity中重寫onResume和onPause方法實(shí)現(xiàn)狀態(tài)欄的禁用和解除禁用。另：StatusBarManager是一個隱藏類，所以調(diào)用的時候可能導(dǎo)入不了包會報(bào)錯，最簡單的方法就是之間用數(shù)值替換，下面列出對應(yīng)關(guān)系。public

DISABLE_SEARCH;所以不能引用StatusBarManager的同學(xué)之間使用其數(shù)值是一樣的。如果有源碼的朋友，可以使用系統(tǒng)編譯的后frameworkjar包作為APP的lib就可以直接使用StatusBarManager方法了。其路徑為/out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/classes.jar。將classes.jar改為framework.jar導(dǎo)入工程就OK了。通過上面的步驟我們知道最關(guān)鍵的就是調(diào)用PhoneStatusBar中disable()方法，我們這里是以廣播的方式實(shí)現(xiàn)的，任何有新方法的同學(xué)可以腦洞大開，只要能實(shí)現(xiàn)調(diào)用到disable()就可以禁用狀態(tài)欄。2.修改PhoneWindowManager路徑:==/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()

{

boolean

ret

=

false;

ret

=

Settings.System.getInt(mContext.getContentResolver(),"status_bar_disabled",

0)

==

1;

return

ret;

}

});在SystemGesturesPointerEventListener.Callbacks的方法中增加一個判斷函數(shù)isGestureIsolated()用于判斷是否支持其對應(yīng)的手勢操作。在這里特別說明一下，在網(wǎng)上找到方法用private

boolean

isGestureIsolated()

{

boolean

ret

=

false;

WindowState

win

=

mFocusedWindow

!=

null

?

mFocusedWindow:mTopFullscreenOpaqueWindowState;

if

(win

!=

null

&&

(win.getSystemUiVisibility()

&

View.SYSTEM_UI_FLAG_IMMERSIVE_GESTURE_ISOLATED)

!=

0)

ret

=

true;

else

ret

=

false;

return

ret;

}getSystemUiVisibility()這種方式做判斷的時候，獲取到的win不一定是當(dāng)前activity的，有時候是statusbar的，所以這樣的效果不是很好，經(jīng)常會下拉出狀態(tài)欄，于是就有了Settings.System.getInt(mContext.getContentResolver(),"status_bar_disabled",

0)

==

1;做判斷的方法，用這種方式有一個好處就是非常直接，需要它禁止下拉的時候，就調(diào)用Settings.System.putInt(getContentResolver(),

"status_bar_disabled",

1);就OK了，解除禁止的時候調(diào)用Settings.System.putInt(getContentResolver(),

"status_bar_disabled",

0);看下Activity中的具體調(diào)用@Override

protected

void

onResume()

{

super.onResume();

//禁止下拉

Settings.System.putInt(getContentResolver(),

"status_bar_disabled",

1);

}

@Override

protected

void

onPause()

{

super.onPause();

//解除禁止

Settings.System.putInt(getContentResolver(),

"status_bar_disabled",

0);

}在AndroidManifest.xml中聲明相應(yīng)的權(quán)限<uses-permission

android:name="android.permission.WRITE_SETTINGS"

/>網(wǎng)上還有修改PhoneWindowManager中的adjustSystemUiVisibilityLw方法的，如:@Override

public

int

adjustSystemUiVisibilityLw(int

visibility){

if

(Settings.System.getInt(mContext.getContentResolver(),"status_bar_disabled",

0)

==

0)

{

mStatusBarController.adjustSystemUiVisibilityLw(mLastSystemUiFlags,

visibility);

}

mNavigationBarController.adjustSystemUiVisibilityLw(mLastSystemUiFlags,

visibility);

//

Reset

any

bits

in

mForceClearingStatusBarVisibility

that

//

are

now

clear.

mResettingSystemUiFlags

&=

visibility;

//

Clear

any

bits

in

the

new

visibility

that

are

currently

being

//

force

cleared,

before

reporting

it.

return

visibility

&

~mResettingSystemUiFlags

&

~mForceClearedSystemUiFlags;

}在adjustSystemUiVisibilityLw增加一個標(biāo)志的判斷，但這種實(shí)現(xiàn)的效果也不是很好，還是會出現(xiàn)下拉能拉下來的情況。綜上所敘，修改PhoneWindowManager實(shí)現(xiàn)禁止下拉的方法還是在SystemGesturesPointerEventListener.Callbacks中增加一個內(nèi)部方法，這個內(nèi)部方法使用標(biāo)志位的形式來判斷是否支持狀態(tài)欄下拉。3.使用StatusBarManager中方法因?yàn)镾tatusBarManager是隱藏方法，所以要在IDE中直接使用的話要導(dǎo)入frameworkjar包，怎么找到frameworkjar在1.修改SystemUI中有說過，這里就不重復(fù)了。直接上代碼：1.在AndroidManifest.xml中聲明相應(yīng)的權(quán)限<uses-permission

android:name="android.permission.STATUS_BAR"/>

<uses-permission

android:name="android.permission.EXPAND_STATUS_BAR"/>網(wǎng)上有文章說要聲明android

:

sharedUserId="android.uid.system"親自測試沒有加上面這行代碼，也是可以使用的。2.在Activity中的引用@Override

protected

void

onResume()

{

super.onResume();

StatusBarManager

statusBarManager

=

(StatusBarManager)

getSystemService(Context.STATUS_BAR_SERVICE);

statusBarManager.disable(StatusBarManager.DISABLE_EXPAND);

}

@Override

protected

void

onPause()

{

super.onPause();

StatusBarManager

statusBarManager

=

(StatusBarManager)

getSystemService(Context.STATUS_BAR_SERVICE);

statusBarManager.disable(StatusBarManager.DISABLE_NONE);

}1.是使用系統(tǒng)簽名，編譯為系統(tǒng)appjava

-jar

signapk.jar

platform.x
