fullScreen时的软键盘监听(非重写Layout方式)

应用场景:

manifest中activity设置如下属性:

android:windowSoftInputMode="stateHidden"
android:theme="@android:style/Theme.Light.NoTitleBar.Fullscreen"

 此时按照网上搜索的通常方法,重写linearLayout,会不起作用,因为layout的bottom属性在全屏中不变。

改用api 1就有ViewTreeObserver来监听layout变化:

//获取最外层Layout
final View rootView=((ViewGroup)findViewById(android.R.id.content)).getChildAt(0);
		
rootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
			
			@Override
			public void onGlobalLayout() {
                                Rect rect = new Rect();
				rootView.getWindowVisibleDisplayFrame(rect);

				int rootHeight=rootView.getRootView().getHeight();

				int displayHeight=rect.height();
                                int diffHeight=rootHeight-displayHeight;
				if(diffHeight==0){
                                //键盘收起
                                }else{
                                //键盘弹出
                                }
                      }
});
