android监听系统状态栏的显示与隐藏(全屏与否)

这个东搞了几天了,累啊!今天终于有个结果,同志们要找办法的只看３就行了,其他的我只用作记录过程

１.想通过,获取当前ACtivity获取,只有ACtivity才能有getWindow() 可是拿不到Activity的实例啊,

PhoneStatusBarView.java:

/* Rect outRect = new Rect();

getWindowVisibleDisplayFrame(outRect);

int statusHeight = outRect.top;

WindowManager windowManager=(WindowManager) context.getSystemService(Context.WINDOW_SERVICE);

Display display=windowManager.getDefaultDisplay();

Log.v(TAG, "statusBarHeight =====================statusHeight= " + statusHeight);

Log.v(TAG, "statusBarHeight =====================display.getHeight()= " + display.getHeight());

//View.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);

//int statusBarHeight = frame.top;

Log.v(TAG, "statusBarHeight ====================== " + statusBarHeight);*/

２.通过phoneStatusBar 的方法setSystemUiVisibility(int vis)找思路:又找到相关资料:http://blog.csdn.net/casun_li/article/details/8963622

但还是无门啊:activity.getWindow().getDecorView().getSystemUiVisibility();只能拿到自己Ｖiew的Visibility值

OnSystemUiVisibilityChangeListener监听的应该是navigate bar(有待验证)

/* Activity activity=((SystemUIApplication)context.getApplicationContext()).mActivity;

Log.v(TAG, "PhoneStatusBarView +++++++++++++++++++++=activity =" + activity);

mContext=context;

setOnSystemUiVisibilityChangeListener(new OnSystemUiVisibilityChangeListener() {

@Override

public void onSystemUiVisibilityChange(int visibility) {

Log.v(TAG, "@@@@@@@@@@@@@@@@@@@onSystemUiVisibilityChange ======visibility =" +visibility);

}

});*/

/* Activity activity=((SystemUIApplication)mContext.getApplicationContext()).mActivity;

Log.v(TAG, "afterOnLayout ***********************************activity =" + activity);

if(android.os.Build.VERSION.SDK_INT>=11){

int vi=activity.getWindow().getDecorView().getSystemUiVisibility();

int thisvi=getSystemUiVisibility();

Log.v(TAG, "afterOnLayout ***********************************vi =" + vi+ " thisvi =" + thisvi);

setSystemUiVisibility(SYSTEM_UI_FLAG_HIDE_NAVIGATION);

setSystemUiVisibility(SYSTEM_UI_FLAG_LOW_PROFILE);

vi=activity.getWindow().getDecorView().getSystemUiVisibility();

thisvi=getSystemUiVisibility();

Log.v(TAG, "++++++afterOnLayout*******************************vi =" + vi+ " thisvi =" + thisvi);

activity.getWindow().getDecorView().setOnSystemUiVisibilityChangeListener(new OnSystemUiVisibilityChangeListener() {

@Override

public void onSystemUiVisibilityChange(int visibility) {

Log.v(TAG, "2@@@@@@@@@@@@@@@@@@@onSystemUiVisibilityChange ======visibility =" +visibility);

}

});

}*/

３.这才是正道啊:将一个view用WindowManager加到窗口:add ,这个View 注册上:OnGlobalLayoutListener 大功告成

写的不详细啊,请大家不要怪,网上找不到这方法啊,至少我没找到

WindowManager.LayoutParams localLayoutParams = new WindowManager.LayoutParams();

localLayoutParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY;//2006;

localLayoutParams.gravity = Gravity.RIGHT | Gravity.TOP;

localLayoutParams.flags = 8;

localLayoutParams.width = 1;

localLayoutParams.height = LayoutParams.MATCH_PARENT;

localLayoutParams.format = PixelFormat.TRANSPARENT;

mWindowHelper=new View(context);

mWindowManager=(WindowManager)context.getSystemService(Context.WINDOW_SERVICE);

mScreenHeight=mWindowManager.getDefaultDisplay().getHeight();

mScreenWidth=mWindowManager.getDefaultDisplay().getWidth();

mWindowManager.addView(this.mWindowHelper, localLayoutParams);

this.mWindowHelper.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {

@Override

public void onGlobalLayout() {

try {

int height=PhoneStatusBarView.this.mWindowHelper.getHeight();

Log.d(TAG, "@@@@@@@@@@@@@@@@@@@==onGlobalLayout() ======height =" +height);

Log.d(TAG, "@@@@@@@@@@@@@@@@@@@==onGlobalLayout() ======mCurrentOrientation =" +mCurrentOrientation);

Log.d(TAG, "@@@@@@@@@@@@@@@@@@@==onGlobalLayout() ======mScreenWidth =" +mScreenWidth);

Log.d(TAG, "@@@@@@@@@@@@@@@@@@@==onGlobalLayout() ======mScreenHeight =" +mScreenHeight);

switch (PhoneStatusBarView.this.mCurrentOrientation) {

case Configuration.ORIENTATION_LANDSCAPE:

if(height==mScreenWidth){

//hide

Log.d(TAG, "@@@@@@@@@@@@@@@@@@@==onGlobalLayout() ======hide...........");

mHandler.removeMessages(MSG_HIDE_STATUS_BAR);

mHandler.sendEmptyMessage(MSG_HIDE_STATUS_BAR);

//mHandler.sendEmptyMessageDelayed(MSG_HIDE_STATUS_BAR, 0);

}else if(height<mScreenWidth){

//show

Log.d(TAG, "@@@@@@@@@@@@@@@@@@@==onGlobalLayout() ======show...........");

mHandler.removeMessages(MSG_SHOW_STATUS_BAR);

mHandler.sendEmptyMessage(MSG_SHOW_STATUS_BAR);

//mHandler.sendEmptyMessageDelayed(MSG_SHOW_STATUS_BAR, 200);

}

break;

default:

if(height==mScreenHeight){

//hide

Log.d(TAG, "@@@@@@@@@@@@@@@@@@@==onGlobalLayout() ======hide...........");

mHandler.removeMessages(MSG_HIDE_STATUS_BAR);

mHandler.sendEmptyMessage(MSG_HIDE_STATUS_BAR);

//mHandler.sendEmptyMessageDelayed(MSG_HIDE_STATUS_BAR, 200);

}else if(height<mScreenHeight){

//show

Log.d(TAG, "@@@@@@@@@@@@@@@@@@@==onGlobalLayout() ======show...........");

mHandler.removeMessages(MSG_SHOW_STATUS_BAR);

mHandler.sendEmptyMessage(MSG_SHOW_STATUS_BAR);

//mHandler.sendEmptyMessageDelayed(MSG_SHOW_STATUS_BAR, 200);

}

break;

}

} catch (Exception e) {

// TODO: handle exception

}

}

});

引发的android.os.DeadObjectException　异常:　　1.请注意注册与取消 2.将mWindowHelper放在服务中,不要放在另一个View中.(否则meizu手机出错,但其他手机正常)

private boolean mAddWindowHelper=false;

public void addWindowHelper(){

if(mAddWindowHelper)return;

Log.d(TAG, " addWindowHelper()... mOnGlobalLayoutListener= "+mOnGlobalLayoutListener);

try {

mWindowManager.addView(this.mWindowHelper, localLayoutParams);

this.mWindowHelper.getViewTreeObserver().addOnGlobalLayoutListener(mOnGlobalLayoutListener);

mAddWindowHelper=true;

} catch (Exception e) {

Log.e(TAG, " Exception e: "+e.getMessage());

}

}

public void removeWindowHelper() {

if(!mAddWindowHelper)return;

Log.d(TAG, " removeWindowHelper()... mOnGlobalLayoutListener= "+mOnGlobalLayoutListener);

try {

this.mWindowHelper.getViewTreeObserver().removeGlobalOnLayoutListener(mOnGlobalLayoutListener);

mWindowManager.removeView(this.mWindowHelper);

mAddWindowHelper=false;

} catch (Exception e) {

Log.e(TAG, " Exception e: "+e.getMessage());

}

}

4.采用3. 以前的方法:在OnLayout()方法里面调用afterLayout(): 这样就有了全屏的问题,弹出tick后,特别是在4..2.２中

@Override

protected void onLayout(boolean changed, int l, int t, int r, int b) {

Log.v(TAG, "onLayout ====================== ");

super.onLayout(changed, l, t, r, b);

//afterOnLayout();

}

private void afterOnLayout(){

getWindowVisibleDisplayFrame(mRect);

int newTop = mRect.top;

Log.d(TAG,"*****************************************rc.top === "+newTop);

Log.d(TAG, "*****************************************mOldTop === "+mOldTop);

Log.d(TAG, "******************* PhoneStatusBar.mIsExpanding="+PhoneStatusBar.mIsExpanding);

Log.d(TAG, "**************************************** isRemoteEvent="+isRemoteEvent);

if (PhoneStatusBar.mIsExpanding || isRemoteEvent) {

newTop = statusBarHeight; // 拉下来时显示自己的状态栏View 当为全屏时,收回时隐藏自己的状态栏View

isRemoteEvent = false;

//服务没开 当为全屏时,有时会隐藏不了,所以这里处理一下,收回时隐藏自己的状态栏View

//因为PhoneStatusBar.mIsExpanding还是==true;

//Log.d(TAG, "+++++++++++++++++++ Service.isRuning()="+EspierNotificationsService.isRuning());

//Log.d(TAG, "+++++++++++++++++++ mService.mAnimating="+mService.mAnimating);

if(!EspierNotificationsService.isRuning() && PhoneStatusBar.mIsExpanding && mService.mAnimating){

mHandler.removeMessages(MSG_AFTER_LAYOUT);

mHandler.sendEmptyMessageDelayed(MSG_AFTER_LAYOUT, 200);

}

}

if (newTop != mOldTop) {

if (newTop == 0) {

windowManagerParams.height = 0;

RemoteStatusBarService.getInstance(getContext()).sendRemoteBroadcast();

} else {

windowManagerParams.height = statusBarHeight;

}

mOldTop = newTop;

updateViewPosition();

}

}

private void updateViewPosition() {

try {

Log.d(TAG, "&&&&&&&&&&&&&&&&&&&&&&&+ updateViewPosition().....windowManagerParams.height="+windowManagerParams.height);

//4.2.2系统:　在视频播放时状态栏就是不消失,其他更新状态栏的方法(如更新时间)全没作用:原因不明

//因此在windowManagerParams.height让状态栏Gone

if(android.os.Build.VERSION.SDK_INT>=17 ){

if(windowManagerParams.height==0){

windowManager.removeView(this);

windowManager.addView(this, windowManagerParams);

}else{

windowManager.updateViewLayout(this, windowManagerParams);

}

}else{

windowManager.updateViewLayout(this, windowManagerParams);

}

} catch (Exception e) {

e.printStackTrace();

Log.e(TAG, "&&&&&&&&&&&&&&&&&&&&&&& updateViewPosition().....e="+e.getMessage());

}

}
