如何从服务中获取窗口? [英] How to get window from a Service?

问题描述

我使用 WindowManager 制作了一个没有 Activity 的 View.

I made a View without an Activity by using the WindowManager.

我想改变视图的状态，如下所示:

I want to change the state of the 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);

但我不能在 Service 中使用 getWindow().

but I cannot use getWindow() in a Service.

有没有办法做到这一点?

Is there a way to do this?

推荐答案

您不能在服务中获得窗口.但是您可以使用WindowManager像您一样添加一个视图(根).

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

并且您还可以通过 updateViewLayout，您可以像下面的代码一样更改窗口的状态(窗口类型、标志、x、y、w、h、重力等...).

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);
