是有没有人知道如何getWindow（）服务在Android？ [英] are there anybody know how to getWindow() in service on android?

问题描述

我通过窗口管理器，在不活动视图。

I made a View without Activity by using WindowManager.

但我不得不改变视图状态像下面

but I have to change state of view like below

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN, WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);

但getWindow（）的服务将无法使用。

but getWindow() can not use in service.

有什么办法？

推荐答案

您不可以得到一个服务的窗口。但是，您可以使用 窗口管理 添加为你已经做了一个视图（根）。

You can't get a window in a Service. But you can use WindowManager to add a view(root) as you did already.

和您还可以更新视图通过<一个href="http://developer.android.com/reference/android/view/ViewManager.html#updateViewLayout%28android.view.View,%20android.view.ViewGroup.LayoutParams%29"相对=nofollow> updateViewLayout ，你可以改变你的窗口的状态（窗式，旗，X，Y，W，H，重力等）中包含codeS。

And You can also update view through updateViewLayout, you can change your window's status(window type, flag, x, y, w, h, gravity, etc...) like below codes.

private WindowManager mWindowManager;
private WindowManager.LayoutParams mLayoutParams;
..........

//let's assume that an event occurred
if(mConfiguration.orientation==Configuration.ORIENTATION_LANDSCAPE){
    mLayoutParams.screenOrientation=Configuration.ORIENTATION_PORTRAIT;
}
mLayoutParams.softInputMode=WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN;

mLayoutParams.gravity = Gravity.TOP|Gravity.CENTER; 
int flag=0
            |WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN
            |WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
            |WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM
            ; 
mLayoutParams.flags=flag;

mWindowManager.updateViewLayout(mRootView, mLayoutParams);
