关于DrawerLayout的小问题

• 问题描述：在开发中用作DrawerView的控件，在拖出时是附带阴影。想要取消掉；

• 解决思路：先百度。 给出两种解决办法

drawableLayout.setScrimColor(Color.TRANSPARENT);
drawableLayout.setDrawerShadow(R.drawable.shape_transparent, GravityCompat.START);

很明显不是我遇到的，网上通常解决的是边上的灰色遮盖。

我后来翻看源码，看到Elevation,便想到这是高度的原因。再仔细找找看到了下面这些代码

/**
     * Sets the base elevation of the drawer(s) relative to the parent, in pixels. Note that the
     * elevation change is only supported in API 21 and above.
     *
     * @param elevation The base depth position of the view, in pixels.
     */
    public void setDrawerElevation(float elevation) {
        mDrawerElevation = elevation;
        for (int i = 0; i < getChildCount(); i++) {
            View child = getChildAt(i);
            if (isDrawerView(child)) {
                ViewCompat.setElevation(child, mDrawerElevation);
            }
        }
    }

结果显而易见了

drawableLayout.setDrawerElevation(0f);
