在实现popupwindow显示及消失的功能时,功能代码如下:  
if (mViewReleasePop == null) \{  
mViewReleasePop = LayoutInflater.from(mActivity).inflate(R.layout.layout\_relaease\_secret, null);  
\}  
if (mReleasePopupWindow == null) \{

mReleasePopupWindow = new PopupWindow(mViewReleasePop, LinearLayout.LayoutParams.MATCH_PARENT
                    , LinearLayout.LayoutParams.WRAP_CONTENT);
            mReleasePopupWindow.setFocusable(true);
            mReleasePopupWindow.setOutsideTouchable(true);
    
            mReleasePopupWindow.setOnDismissListener(new PopupWindow.OnDismissListener() {
                @Override
                public void onDismiss() {
                    WindowManager.LayoutParams lp = mActivity.getWindow().getAttributes();
                    lp.alpha = 1.0f;
                    mActivity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
                    mActivity.getWindow().setAttributes(lp);
                }
            });
        }
    
        if (mReleasePopupWindow != null && mReleasePopupWindow.isShowing()) {
            return;
        }
    
        mReleasePopupWindow.setAnimationStyle(R.style.showPopupAnimation);
        mReleasePopupWindow.showAtLocation(mParentLinearl, Gravity.BOTTOM, 0, 0);
    
        WindowManager.LayoutParams lp = mActivity.getWindow().getAttributes();
        lp.alpha = 0.3f;
        mActivity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
        mActivity.getWindow().setAttributes(lp);

功能测试时发现在6.0以上版本功能是正常，但是低于6.0的安卓手机上，点击外部不会消失，并且点击返回键的onKeyDown事件都被拦截掉了，对比之前写的功能正常的代码，发现少了一句代码，

mReleasePopupWindow.setBackgroundDrawable();
            因为目前没有背景，就写成
            mReleasePopupWindow.setBackgroundDrawable(new PaintDrawable(Color.TRANSPARENT));

添加之后，在4.4，5.0，6.0机器上测试，功能都恢复了正常，特此记录。
