記一次實(shí)現(xiàn)左滑關(guān)閉頁面 返回上個頁面，雖然實(shí)現(xiàn)的不完美 但這也是一種實(shí)現(xiàn)方式 記錄學(xué)習(xí)的過程
     實(shí)現(xiàn)方式是v4 包下的 SlidingPaneLayout 


     private void SlideBackClose() {
              SlidingPaneLayout slidingPaneLayout = new SlidingPaneLayout(this);
    try {
        Field overhangSize = SlidingPaneLayout.class.getDeclaredField("mOverhangSize");
        overhangSize.setAccessible(true);
        overhangSize.set(slidingPaneLayout, 0);
    } catch (Exception e) {
        e.printStackTrace();
    }
    slidingPaneLayout.setPanelSlideListener(new SlidingPaneLayout.PanelSlideListener() {
        @Override
        public void onPanelSlide(View panel, float slideOffset) {

        }

        @Override
        public void onPanelOpened(View panel) {
            finish();
        }

        @Override
        public void onPanelClosed(View panel) {

        }
    });
    slidingPaneLayout.setSliderFadeColor(getResources()
            .getColor(android.R.color.transparent));
    View leftView = new View(this);
    leftView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
    slidingPaneLayout.addView(leftView, 0);
    ViewGroup decorView = (ViewGroup) getWindow().getDecorView();
    ViewGroup decorChild = (ViewGroup) decorView.getChildAt(0);
    decorChild.setBackgroundColor(getResources()
            .getColor(android.R.color.white));
    decorView.removeView(decorChild);
    decorView.addView(slidingPaneLayout);
    slidingPaneLayout.addView(decorChild, 1);
      }
