首先, DrawerLayout这个类是在Support Library里的,需要加上android-support-v4.jar这个包。 然后程序中用时在前面导入import android.support.v4.widget.DrawerLayout; 如果找不到这个类,首先用SDK Manager更新一下Android Support Library,然后在Android SDK/extras/android/support/v4
路径下找到android-support-v4.jar,复制到项目的libs路径,将其Add to Build Path.
http://developer.android.com/reference/android/support/v4/widget/DrawerLayout.html
打开抽屉: DrawerLayout .openDrawer(); 关闭抽屉:DrawerLayout.closeDrawer( );
要注意这几个原则:
1.主view(content view) 必须是drawerlayout的第一个子节点
2.主view宽和高必需match_parent
3.drawer view必须指定android:layout_gravity属性,如果值为“start”,会根据系统的语言顺序自动决定从左滑还是从右
滑
4. drawer view宽度不能太宽,最好不要超过320dp
