android – 无法在导航抽屉的ActionBar中更改应用程序图标旁边的向上插入符号
我目前正在尝试按照Google IO 2013指南实施新的NavigationDrawer.我正在使用ActionbarSherlock.代码运行良好.唯一的问题是,当拉出导航抽屉时,我无法切换应用程序图标旁边的“向上”插入符号.我在下面粘贴我的整个代码.请帮助.

解决方法
如果你不需要移动3行(比如在gmail应用程序中),你可以添加：
<item name="homeAsUpIndicator">@drawable/ic_drawer</item> <item name="android:homeAsUpIndicator">@drawable/ic_drawer</item>
在你的活动主题中.我更喜欢在我的应用程序中使用另一个库.
ic_drawer可以从这里下载：

Android ActionBar /工具栏消失在我的应用程序中
所以我有一个应用程序.目前有3个活动…我正在用意图从另一个活动中启动活动
MainActivity > ChallongeLogin > ChallongeEvents
在我的MainActivity和ChallongeLogin中,应用程序顶部有一个大栏,列出了我的应用程序名称.但是,当我最终阅读ChallongeEvents时,该条消失了……我不记得做任何特别的事情使该条消失了.为什么消失了？

解决方法:
根据您的要求,您必须扩展AppCompatActivity而不是Activity.
public class ActivityName extends AppCompatActivity {
// ...
}
AppCompatActivity is from the appcompat-v7 library. Principally, this
offers a backport of the action bar. Since the native action bar was
added in API Level 11, you do not need AppCompatActivity for that.
However, current versions of appcompat-v7 also add a limited backport
of the Material Design aesthetic, in terms of the action bar and
varIoUs widgets. There are pros and cons of using appcompat-v7, well
beyond the scope of this specific Stack Overflow answer.

Android NavigationView 导航抽屉的使用
1.抽屉布局(drawerlayout)
activity_main.xml中的总体布局设置为drawerlayout
2.拖入NavigationView组件(在container中)
3.给NavigationView组件设置头部布局
<1>在app--->src--->main-->res-->layout中新建NavigationView组件headlayout对应的head_layout.xml布局文件
<2>在activity_main.xml文件中添加head_layout.xml的对应关系
app:headerLayout="@layout/head_layout"
4.给NavigationView组件添加菜单
<1>app--->src--->main--->res,选中res,右击new--->android resource file
<2>设置抽屉组件在屏幕的左侧
android:layout_gravity="left"
<3>在activity_main.xml文件中添加menu_navi.xml的对应关系
app:menu="@menu/menu_navi"
<4>navigation总体xml代码设置
<android.support.design.widget.NavigationView
android:id="@+id/navi"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="left"
app:headerLayout="@layout/head_layout"
app:menu="@menu/menu_navi" />
5.java后台代码
public class MainActivity extends AppCompatActivity {
NavigationView navigationView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
navigationView=findViewById(R.id.navi); //天坑：navigation一定要初始化
navigationView.setItemIconTintList(null); //设置navigationView菜单的图标
View view=navigationView.getHeaderView(0); //获取抽屉的头部
ImageView imageView=view.findViewById(R.id.imageView); //获取头部的图片组件
imageView.setonClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(MainActivity.this,"您选择的是头部组件",Toast.LENGTH_SHORT).show();
}
});
final TextView textView=view.findViewById(R.id.textView3);
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
textView.setText("您选择的是："+menuItem.getTitle().toString());
return true;
}
});
}
}
Android UI ActionBar功能-Action Bar 左上角的向上或返回按钮
ActionBar在左上角还提供了一个向上或返回的按钮，默认情况下是隐藏的需要在代码中开启：
官方文档：http://wear.techbrood.com/training/basics/actionbar/adding-buttons.html#UpNav
向上功能：
先打开功能选项，设置ActionBar的DisplayHomeAsUpEnabled=true：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getActionBar().setDisplayHomeAsUpEnabled(true);
}public class ParentActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.parent_activity);
}
}<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="parent activity">
</TextView>
</LinearLayout>然后在AndroidManifest.xml文件中配置向上功能：
详细请查看上方的官方说明文档；
返回功能：
先打开功能选项，设置ActionBar的DisplayHomeAsUpEnabled=true：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getActionBar().setDisplayHomeAsUpEnabled(true);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
finish();
break;
default:
break;
}
return super.onOptionsItemSelected(item);
}
android – ActionBarCompat – 应用程序图标操作(点击)不能在4.0设备上工作
我有
Android ActionBarCompat项目的这个问题：在Android 4.0的模拟器上,单击应用程序图标不会导致任何onoptionsItemSelected事件,而它适用于所有其他操作系统版本.
任何输入都非常感谢！
解决方法
您是否看到应用图标有任何触摸反馈？ (当你按下它会发光吗？)
由于许多活动不使用操作栏主页按钮,因此在Android 4.0上运行的API 14应用程序中,默认情况下禁用. (这样,用户不要尝试按它,看到它发光,并想知道为什么没有发生.)想要使用这个应用程序应该调用ActionBar#setHomeButtonEnabled(true).
我们应该修改ActionBarCompat样本,使之更清楚.让您开始运行的一个简单方法是修改ActionBarHelperICS.java并添加以下内容：
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mActivity.getActionBar().setHomeButtonEnabled(true);
}
在一个应用程序中,您需要更多的控制来打开和关闭此功能,您将需要进行进一步的更改.
