纠结...

Answer 1

Caused by: java.lang.IllegalArgumentException: The handle attribute is must refer to an existing child.
看这个错误，
看了下资料@Override
    protected void onFinishInflate() {
        mHandle = findViewById(mHandleId);
        if (mHandle == null) {
            throw new IllegalArgumentException("The handle attribute is must refer to an"
                    + " existing child.");
        }
        mHandle.setOnClickListener(new DrawerToggler());        mContent = findViewById(mContentId);
        if (mContent == null) {
            throw new IllegalArgumentException("The content attribute is must refer to an" 
                    + " existing child.");
        }
        mContent.setVisibility(View.GONE);
    }mHandle或mContent 是空的话就有这个问题。        int handleId = a.getResourceId(R.styleable.SlidingDrawer_handle, 0);
        int contentId = a.getResourceId(R.styleable.SlidingDrawer_content, 0);确认你的sdk里有这个SlidingDrawer_handle和SlidingDrawer_content的资源。
你可以在程序里试试getResourceId这两句话，应该是里面有一个的空的

Answer 2

你在mapView上用这个，呵呵，那会是什么样子的呢
