Answer 1

您使用的ArrayAdapter构造函数假定布局仅包含一个TextView。要使用还包括RelativeLayout的布局，您需要使用constructor，它允许您指定适配器将使用的TextView。

代替

mDrawerList.setAdapter(new ArrayAdapter<String>(this,
    R.layout.drawer_list_icon, mPlanetTitles));

采用

mDrawerList.setAdapter(new ArrayAdapter<String>(this,
    R.layout.drawer_list_icon, android.R.id.text1, mPlanetTitles));
