今天帮助哥们解决了一个比较蛋疼的问题，就是在有的情况下会出现设置activity的windowSoftInputMode="adjustResize"时，会失效的情况。

历尽千辛万苦，终于在stackflow上找到解决方法。在activity的根布局上添加fitsSystemWindows="true".

然后adjustResize就可以成功的起作用了。但是在这种情况下，你的titlebar会下移statusbar的高度的距离。所以就必须重写一个layout继承自你所使用的layout，并重写其中的两个方法，贴出代码:

 public class MyLinearLayout extends LinearLayout{

     private int[] mInsets = new int[4];

     public MyLinearLayout(Context context) {
         super(context);
     }

     public MyLinearLayout(Context context, AttributeSet attrs) {
         super(context, attrs);
     }

     public MyLinearLayout(Context context, AttributeSet attrs, int defStyleAttr) {
         super(context, attrs, defStyleAttr);
     }

     @TargetApi(Build.VERSION_CODES.LOLLIPOP)
     public MyLinearLayout(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
         super(context, attrs, defStyleAttr, defStyleRes);
     }

     @Override
     protected final boolean fitSystemWindows(Rect insets) {
         if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
             // Intentionally do not modify the bottom inset. For some reason,
             // if the bottom inset is modified, window resizing stops working.
             // TODO: Figure out why.

             mInsets[0] = insets.left;
             mInsets[1] = insets.top;
             mInsets[2] = insets.right;

             insets.left = 0;
             insets.top = 0;
             insets.right = 0;
         }

         return super.fitSystemWindows(insets);
     }

     @Override
     public final WindowInsets onApplyWindowInsets(WindowInsets insets) {
         if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT_WATCH) {
             mInsets[0] = insets.getSystemWindowInsetLeft();
             Log.e("mInsets[0]",""+mInsets[0]);
             mInsets[1] = insets.getSystemWindowInsetTop();
             Log.e("mInsets[1]",""+mInsets[1]);
             mInsets[2] = insets.getSystemWindowInsetRight();
             Log.e("mInsets[2]",""+mInsets[2]);
             return super.onApplyWindowInsets(insets.replaceSystemWindowInsets(0, 0, 0,
                     insets.getSystemWindowInsetBottom()));
         } else {
             return insets;
         }
     }
}

自己也记录一下。
