@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.dialog_share);
    Window window = this.getWindow();
    if (window != null) {
        window.setGravity(Gravity.BOTTOM);  //设置dialog显示的位置
        window.setWindowAnimations(R.style.more_dialog_anim_style); //添加动画

        //解决 状态栏变色的bug

                    Field field = decorViewClazz.getDeclaredField("mSemiTransparentStatusBarColor");
                    field.setAccessible(true);
                    field.setInt(getWindow().getDecorView(), Color.TRANSPARENT);  //去掉高版本蒙层改为透明
                } catch (Exception e) {}
