结合菜单和Tab [英] Combining Menu and Tab
问题描述
我用这标签的布局和ListView从的 http://www.androidhive.info/2012/05/android-combining-tab-layout-and-list-view/ 和Android的菜单，从的 http://www.androidhive.info/2011/09/how-to-create-android-菜单/ 。
我把它们合并在一起，但它不工作。的标签工作，但不为菜单。
这里是我的codeS。
I am using this "Tab layout and Listview" from http://www.androidhive.info/2012/05/android-combining-tab-layout-and-list-view/ and "Android Menus" from http://www.androidhive.info/2011/09/how-to-create-android-menus/. I merge them together, yet it doesn't work. The tab works, but not for the menu. Here are my codes.
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.widget.Toast;
public class optionMenuActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
// Initiating Menu XML file (menu.xml)
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
MenuInflater menuInflater = getMenuInflater();
menuInflater.inflate(R.layout.menu, menu);
return true;
}
/**
* Event Handling for Individual menu item selected
* Identify single menu item by it's id
* */
@Override
public boolean onOptionsItemSelected(MenuItem item)
{
Intent myList = new Intent();
switch (item.getItemId())
{
case R.id.menu_login:
// Single menu item is selected do something
// Ex: launching new activity/screen or show alert message
// Toast.makeText(optionMenuActivity.this, "Bookmark is Selected", Toast.LENGTH_SHORT).show();
myList = new Intent(optionMenuActivity.this, LoginActivity.class);
startActivity(myList);
return true;
case R.id.menu_save:
Toast.makeText(optionMenuActivity.this, "Save is Selected", Toast.LENGTH_SHORT).show();
return true;
case R.id.menu_search:
Toast.makeText(optionMenuActivity.this, "Search is Selected", Toast.LENGTH_SHORT).show();
return true;
case R.id.menu_share:
Toast.makeText(optionMenuActivity.this, "Share is Selected", Toast.LENGTH_SHORT).show();
return true;
case R.id.menu_delete:
Toast.makeText(optionMenuActivity.this, "Delete is Selected", Toast.LENGTH_SHORT).show();
return true;
case R.id.menu_quit:
// Toast.makeText(optionMenuActivity.this, "Preferences is Selected", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
// return true;
default:
return super.onOptionsItemSelected(item);
}
}
}
从标签布局
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>
</TabHost>
这是我menu.xml文件
And this is my menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Single menu item
Set id, icon and Title for each menu item
-->
<item android:id="@+id/menu_login"
android:icon="@drawable/icon_bookmark"
android:title="Login" />
<item android:id="@+id/menu_save"
android:icon="@drawable/icon_save"
android:title="Save" />
<item android:id="@+id/menu_search"
android:icon="@drawable/icon_search"
android:title="Search" />
<item android:id="@+id/menu_share"
android:icon="@drawable/icon_share"
android:title="Share" />
<item android:id="@+id/menu_delete"
android:icon="@drawable/icon_delete"
android:title="Delete" />
<item android:id="@+id/menu_quit"
android:icon="@drawable/icon_preferences"
android:title="Quit" />
</menu>
最后，我的清单。
And lastly, my manifest.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.example"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:name=".WorkDroid5"
android:configChanges="keyboardHidden|orientation"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!-- Inbox Activity -->
<activity android:name=".AnnouncementActivity" />
<!-- Outbox Activity -->
<activity android:name=".HomeworkActivity" />
<!-- Profile Activity -->
<activity android:name=".TimetableActivity" />
<activity android:name=".tt_Friday" />
<activity android:name=".ttFinalDetails" />
<activity android:name=".TimetableAdapter" />
<activity android:name=".tt_Thursday" />
<activity android:name=".tt_Monday" />
<activity android:name=".tt_Tuesday" />
<activity android:name=".tt_Wednesday" />
<activity
android:name=".RegisterActivity"
android:label="Register New Account" >
</activity>
<activity
android:name=".LoginActivity"
android:label="Login to your Account" >
</activity>
<activity
android:name=".optionMenuActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="com.example.example.OPTIONMENUACTIVITY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
<!-- Internet Permissions -->
<uses-permission android:name="android.permission.INTERNET" />
</manifest>
在此先感谢任何人的帮助（

推荐答案
我跑进与TabHost类似的问题。默认情况下，Android的创建你的情况父活动选项菜单，即TabHost。子选项卡未收到 OnCreateOptionsMenu 事件。因此，不创建您的菜单。
I ran into similar problem with TabHost. By default, Android creates an options menu for the parent activity, i.e. TabHost in your case. The child tab does not receive the OnCreateOptionsMenu event. Therefore, your menu is not being created.
把选项菜单中创建/处理code延长TabActivity活动。您可以通过检查哪个选项卡目前通过检查选定 getTabHost.getCurrentTab 或 getTabHost.getCurrentTabTag 和充气相应的菜单。
Put the option menu creation/handling code in the activity extending TabActivity. You can change the preference menu content by checking which tab is currently selected by checking getTabHost.getCurrentTab or getTabHost.getCurrentTabTag and inflating appropriate menu.
