view.getRootView().getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener){

    }
}

当加入沉浸式时，在AndroidManifest中设置android:windowSoftInputMode="stateUnspecified|adjustUnspecified"失效

在代码onCreate()#setContentView()之后加入getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
(使用getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);不可以)
