Question

我是java和android的初学者。我想添加一个抽屉来繁殖活动。我创建了一个基础活动。一切都有效，除非我点击动作栏上的抽屉图标没有显示菜单。怎么了！？

更新我发现当我将DrawerActivity更改为启动活动时，它可以工作，但是当我将MainActivity设置为启动时，图标无效。

Answer 1

可以使用getSupportActionBar()代替getActionBar()方法。并使用DrawerActivity代替ActionBarActivity扩展您的Activity。

Answer 2

将您的onOptionsItemSelected更改为：

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    if (item.getItemId() == android.R.id.home) {
         if (mDrawerLayout.isDrawerOpen(mDrawerList)) {
              mDrawerLayout.closeDrawer(mDrawerList);
         } else {
              mDrawerLayout.openDrawer(mDrawerList);
         }
    }
    return super.onOptionsItemSelected(item);
}

Answer 3

我通过在DrawerActivity中更改onCreate的名称并从MainAcitity的onCreate事件调用它来修复它！
