我的代码做了不同的事情，但没有完全像我想要的那样。
问题 -
当应用程序启动时，主页不显示。
选择项目时，不会隐藏横向栏(NavigationDrawer)。直到我在侧栏外面点击它才显示下一个片段。
请帮助:(

如果您对错误有所了解，请帮我修复行为。
答案 0 :(得分：0)
对于初学者来说，试试这个，当你点击一个项目时它应该隐藏横向栏：
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.menu01, //nav menu toggle icon
R.string.app_name, // nav drawer open - description for accessibility
R.string.app_name // nav drawer close - description for accessibility
) {
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
getActionBar().setTitle(mTitle);
// calling onPrepareOptionsMenu() to show action bar icons
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
//getActionBar().setTitle(mDrawerTitle);
// calling onPrepareOptionsMenu() to hide action bar icons
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
我现在会更深入地研究你的问题。
