隐藏操作栏中的标题并显示图标

Question

我想要一个标题栏，显示各种图标，点击后会将用户引导到相应的活动页面。不幸的是，我遇到了以下问题： - 隐藏活动标题 -Icons未显示在活动栏上，但仅显示为下拉列表

以下是我在android manifest中使用的代码

 <activity
            android:name="com.dooba.beta.MoodActivity"
            android:screenOrientation="portrait"
            android:theme="@android:style/Theme.Holo">
         <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>

        </activity>

下面是菜单xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:id="@+id/pageExperience"
          android:icon="@drawable/fork_spoon3"
          android:title="@string/action_experience"/>

    <item android:id="@+id/pageMessaging"
          android:icon="@drawable/messageicon"
          android:title="@string/action_messaging"/>

    <item android:id="@+id/pageEventsBooking"
          android:icon="@drawable/fork_spoon3"
          android:title="@string/action_book"/>
    <item android:id="@+id/pageProfile"
          android:icon="@drawable/fork_spoon3"
          android:title="@string/action_profile" />
     <item android:id="@+id/pageReport"
          android:icon="@drawable/fork_spoon3"
          android:title="@string/action_report" />
      <item android:id="@+id/pageAbout"
          android:icon="@drawable/fork_spoon3"
          android:title="@string/action_about" />
</menu>

以下是调用菜单的活动代码

@Override
    public boolean onCreateOptionsMenu(Menu menu) {

        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main_activity_actions, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle presses on the action bar items
        switch (item.getItemId()) {
            case R.id.pageExperience:
                openPageExperience();
                return true;
            case R.id.pageMessaging:
                openPageMessage();
                return true;

            case R.id.pageEventsBooking:
                openPageBook();
                return true;

            case R.id.pageProfile:
                openPageProfile();
                return true;

            case R.id.pageReport:
                openPageReport();
                return true;

            case R.id.pageAbout:
                openPageAbout();
                return true;

            default:
                return super.onOptionsItemSelected(item);
        }
    }

    private void openPageAbout() {
        // TODO Auto-generated method stub

    }

    private void openPageReport() {
        // TODO Auto-generated method stub

    }

    private void openPageProfile() {
        // TODO Auto-generated method stub

    }

    private void openPageBook() {
        // TODO Auto-generated method stub

    }

    private void openPageMessage() {
        // TODO Auto-generated method stub

    }

    private void openPageExperience() {
        // TODO Auto-generated method stub

    }

}

下面是引用标题图标字符串名称

的字符串xml文件

   <string name="action_experience">Experience</string>
    <string name="action_messaging">Messaging</string>
     <string name="action_book">Book</string>
    <string name="action_profile">Profile</string>
    <string name="action_report">"Report</string>
        <string name="short_name"></string>

    <string name="action_about">About</string>

更新 尝试实现代码时，我收到了以下问题 ActionBar ab = getActionBar（）; getActionBar 类型不匹配：无法从android.app.ActionBar转换为android.support.v7.app.ActionBar

customActionBarView无法解析为变量 main_activity_actions无法解析或不是字段

活动代码

public class MoodActivity extends Activity {

    @Override
    public void onResume() {
        super.onResume();  // Always call the superclass method first
        setCustomActionBarView();

    }

    private void setCustomActionBarView() {
        // TODO Auto-generated method stub
        ActionBar ab = getActionBar();
        ab.setDisplayHomeAsUpEnabled(false);
        ab.setDisplayShowTitleEnabled(false);
        ab.setDisplayShowCustomEnabled(true);
        if(customActionBarView == null){
            LayoutInflater inflator = (LayoutInflater) this .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            customActionBarView = inflator.inflate(R.layout.main_activity_actions,null);

    }

    private void openPageExperience() {
        // TODO Auto-generated method stub

    }

}

更新 我现在有以下问题： getSupportActionBar（）; 它给了我以下问题： 对于MoodActivity类型

，方法getSupportActionBar（）未定义

@Override
    public void onResume() {
        super.onResume();  // Always call the superclass method first
        setCustomActionBarView();

    }

    private void setCustomActionBarView() {
        // TODO Auto-generated method stub
        ActionBar ab = getSupportActionBar();
        ab.setDisplayHomeAsUpEnabled(false);
        ab.setDisplayShowTitleEnabled(false);
        ab.setDisplayShowCustomEnabled(true);
        View customActionBarView;
        if(customActionBarView == null){
            LayoutInflater inflator = (LayoutInflater) this .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            customActionBarView = inflator.inflate(R.layout.main_activity_actions,null);
        }
        ab.setCustomView(customActionBarView);
    }

Answer 1

ActionBar ab = getActionBar();
ab.setDisplayHomeAsUpEnabled(false);
ab.setDisplayShowTitleEnabled(false);
ab.setDisplayShowCustomEnabled(true);
if(customActionBarView == null){
    LayoutInflater inflator = (LayoutInflater) this .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    customActionBarView = inflator.inflate(R.layout.my_custom_view,null);
}
ab.setCustomView(customActionBarView);

这是它的作用：

setDisplayHomeAsUpEnabled(boolean showHomeAsUp)  

当您使用导航抽屉并且希望用户在视图层次结构中上升级别时，将使用

。

setDisplayShowTitleEnabled(boolean showTitle);  

用于决定是否应显示活动的标题

setDisplayShowCustomEnabled(boolean showCustom);  

用于决定是否要显示ActionBar

的自定义视图

然后，您可以使用customActionBarView.findViewById()检索图标并为其添加侦听器。
