关于全屏模式adjustResize不起作用解决办法， 本来借用官方的AndroidBug5497Workaround 就能解决问题，可是可恨的国产机 华为荣耀就是有问题，会导致底部的TabBar经常显示不出来，看看源码，发现了解决办法：

package com.vocinno.widget;  
      
    import android.app.Activity;  
    import android.graphics.Rect;  
    import android.view.View;  
    import android.view.ViewTreeObserver;  
    import android.widget.FrameLayout;  
      
    /**
     * Created by Administrator on 2016/3/3.
     */  
    public class AndroidBug5497Workaround {  
      
        // For more information, see https://code.google.com/p/android/issues/detail?id=5497  
        // To use this class, simply invoke assistActivity() on an Activity that already has its content view set.  
      
        public static void assistActivity (Activity activity) {  
            new AndroidBug5497Workaround(activity);  
        }  
      
        private View mChildOfContent;  
        private int usableHeightPrevious;  
        private FrameLayout.LayoutParams frameLayoutParams;  
      
        private AndroidBug5497Workaround(Activity activity) {  
            FrameLayout content = (FrameLayout) activity.findViewById(android.R.id.content);  
            mChildOfContent = content.getChildAt(0);  
            mChildOfContent.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {  
                public void onGlobalLayout() {  
                    possiblyResizeChildOfContent();  
                }  
            });  
            frameLayoutParams = (FrameLayout.LayoutParams) mChildOfContent.getLayoutParams();  
        }  
      
        private void possiblyResizeChildOfContent() {  
            int usableHeightNow = computeUsableHeight();  
            if (usableHeightNow != usableHeightPrevious) {  
                int usableHeightSansKeyboard = mChildOfContent.getRootView().getHeight();  
                int heightDifference = usableHeightSansKeyboard - usableHeightNow;  
                if (heightDifference > (usableHeightSansKeyboard/4)) {  
                    // keyboard probably just became visible  
                    frameLayoutParams.height = usableHeightSansKeyboard - heightDifference;  
                } else {  
                    // keyboard probably just became hidden  
                    frameLayoutParams.height = usableHeightNow;  
                }  
                mChildOfContent.requestLayout();  
                usableHeightPrevious = usableHeightNow;  
            }  
        }  
      
        private int computeUsableHeight() {  
            Rect r = new Rect();  
            mChildOfContent.getWindowVisibleDisplayFrame(r);  
            return (r.bottom - r.top);  
        }  
    }

使用起来很容易，在你的setContentView 之后调用：

AndroidBug5497Workaround.assistActivity(this);

完美解决问题 兼容多种手机
