Android 无法启动 Activity，错误膨胀类？

我是安卓新手。我有一些java知识，并且我正在使用Eclipse。 目前，我正在尝试在选项卡中显示地图，并正在查看教程/代码来帮助我。 :)

我已经看到一些关于此错误的问题，但我仍然无法弄清楚我做错了什么。 我正在使用这里的代码： http://vkroz.wordpress.com/2009/07/03/programming-android-%E2%80%93-map-view-within-tab-view/

我只是缺少一些明显的东西？

运行时异常 e: 第 24 行的值

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.test.mapintab/com.test.mapintab.MapInTabActivity}: ... android.view.InflateException: Binary XML file line #24: Error inflating class <unknown>

只是

整个 main.xml:

<?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">

                <RelativeLayout android:id="@+id/emptylayout1" android:orientation="vertical"
                    android:layout_width="fill_parent" android:layout_height="fill_parent"/>

                <TextView android:id="@+id/textview2"
                    android:layout_width="fill_parent" android:layout_height="fill_parent"
                    android:text="Details Details Details Details"/>

        </FrameLayout>
    </LinearLayout> 
</TabHost>

我的其余代码与链接的相同，但我也会将其粘贴到此处。

MapInTabActivity.java

package com.test.mapintab;

import android.app.TabActivity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.widget.FrameLayout;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;

public class MapInTabActivity extends TabActivity {

    TabHost mTabHost;
    FrameLayout mFrameLayout;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        mTabHost = getTabHost();
        TabSpec tabSpec = mTabHost.newTabSpec("tab_test1");
        tabSpec.setIndicator("Map");
        Context ctx = this.getApplicationContext();
        Intent i = new Intent(ctx, MapInTabActivity.class);
        tabSpec.setContent(i);

        mTabHost.addTab(tabSpec);
        mTabHost.addTab(mTabHost.newTabSpec("tab_test2").setIndicator("Details").setContent(R.id.textview2));
        mTabHost.setCurrentTab(0);

    }

}

MapTabView.java：maptabview.xml：Manifest

package com.test.mapintab;

import android.os.Bundle;

import com.google.android.maps.MapActivity;

public class MapTabView extends MapActivity{

    @Override
    protected void onCreate(Bundle icicle){
        super.onCreate(icicle);
        setContentView(R.layout.maptabview);
    }

    @Override
    protected boolean isRouteDisplayed(){
        return false;
    }

}

：

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/maptablayout"
    android:orientation="vertical"
    android:layout_width="fill_parent" android:layout_height="fill_parent">

    <com.google.android.maps.MapView android:id="@+id/mapview"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:clickable="true"            
        android:apiKey="0HRMcD5o6WrBVhmwbWpeyeavZ67PXWOvJeeCx2g"/>

</RelativeLayout>

以及logcat的其余部分（

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.test.mapintab"
    android:versionCode="1"

    <uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS"></uses-permission>

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <uses-library android:name="com.google.android.maps"/>

        <activity
            android:name=".MapInTabActivity" android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

       <activity android:name=".MapTabView" android:label="@string/mapview_name">
           <intent-filter>
              <category android:name="android.intent.category.EMBED"></category>
              <action android:name="android.intent.action.MAIN"></action>
           </intent-filter>
        </activity>

    </application>
</manifest>

我认为重要的部分是我在顶部指出的部分，但也许还有其他我不知道的东西）。

I'm new to android. I have some java knowledge, and I'm using Eclipse.
At the moment I'm trying to display a map within a tab, and am looking at tutorials/code to help me. :)

I've seen a few questions asking about this error, but I can't figure out what I'm doing wrong, still.
I'm using code from here: http://vkroz.wordpress.com/2009/07/03/programming-android-%E2%80%93-map-view-within-tab-view/

Am I just missing something obvious?

The value of the runtime exception e: 

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.test.mapintab/com.test.mapintab.MapInTabActivity}: ... android.view.InflateException: Binary XML file line #24: Error inflating class <unknown>

Line 24 is just </LinearLayout>

The whole of main.xml:

<?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">

                <RelativeLayout android:id="@+id/emptylayout1" android:orientation="vertical"
                    android:layout_width="fill_parent" android:layout_height="fill_parent"/>

                <TextView android:id="@+id/textview2"
                    android:layout_width="fill_parent" android:layout_height="fill_parent"
                    android:text="Details Details Details Details"/>

        </FrameLayout>
    </LinearLayout> 
</TabHost>

The rest of my code is the same as linked, but I'll paste it here too.

MapInTabActivity.java

package com.test.mapintab;

import android.app.TabActivity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.widget.FrameLayout;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;

public class MapInTabActivity extends TabActivity {

    TabHost mTabHost;
    FrameLayout mFrameLayout;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        mTabHost = getTabHost();
        TabSpec tabSpec = mTabHost.newTabSpec("tab_test1");
        tabSpec.setIndicator("Map");
        Context ctx = this.getApplicationContext();
        Intent i = new Intent(ctx, MapInTabActivity.class);
        tabSpec.setContent(i);

        mTabHost.addTab(tabSpec);
        mTabHost.addTab(mTabHost.newTabSpec("tab_test2").setIndicator("Details").setContent(R.id.textview2));
        mTabHost.setCurrentTab(0);

    }

}

MapTabView.java:

package com.test.mapintab;

import android.os.Bundle;

import com.google.android.maps.MapActivity;

public class MapTabView extends MapActivity{

    @Override
    protected void onCreate(Bundle icicle){
        super.onCreate(icicle);
        setContentView(R.layout.maptabview);
    }

    @Override
    protected boolean isRouteDisplayed(){
        return false;
    }

}

maptabview.xml:

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/maptablayout"
    android:orientation="vertical"

    <com.google.android.maps.MapView android:id="@+id/mapview"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:clickable="true"            
        android:apiKey="0HRMcD5o6WrBVhmwbWpeyeavZ67PXWOvJeeCx2g"/>

</RelativeLayout>

Manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.test.mapintab"
    android:versionCode="1"

    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
    <uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS"></uses-permission>

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <uses-library android:name="com.google.android.maps"/>

        <activity
            android:name=".MapInTabActivity" android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

       <activity android:name=".MapTabView" android:label="@string/mapview_name">
           <intent-filter>
              <category android:name="android.intent.category.EMBED"></category>
              <action android:name="android.intent.action.MAIN"></action>
           </intent-filter>
        </activity>

    </application>
</manifest>

And the rest of logcat (I think the important part was the bit I pointed out at the top, but maybe there's something else I don't know about).

修复此问题：

二进制 XML 文件第 #24 行：错误膨胀类

另外，您的模拟器是否使用 Google API 版本？其他版本没有有这个库。

更新

http://developer.android.com /resources/tutorials/views/hello-mapview.html

Fix this:

Binary XML file line #24: Error inflating class <unknown>

Also for your emulator are you use the Google APIs version? The other versions do NOT have this library.

我尝试了您所关注的链接的示例。在我看来它工作得很好。您的清单文件显示，您尚未在清单文件中声明 MapTabView 活动。在您的清单中使用它

<activity android:name=".MapTabView" android:label="@string/mapview_name">
   <intent-filter>
      <category android:name="android.intent.category.EMBED"></category>
      <action android:name="android.intent.action.MAIN"></action>
   </intent-filter>
</activity>

希望这有帮助！

I tried the example that link you are following. Its working fine in my end. Your Manifest file says, you have not declared the MapTabView activity in the Manifest file. Use this in your manifest

<activity android:name=".MapTabView" android:label="@string/mapview_name">
   <intent-filter>
      <category android:name="android.intent.category.EMBED"></category>
      <action android:name="android.intent.action.MAIN"></action>
   </intent-filter>
</activity>

每当你借用代码时，你应该确保你理解所有代码，因为很多事情都可能出错。看来问题出在你的意图上。你有：

Context ctx = this.getApplicationContext();

通常意图与活动上下文而不是应用程序上下文相关，所以我会检查这一点。

Whenever you borrow code you should make sure you understand all of it, because a lot can go wrong. It seems like the problem is with your intent. You have: 

Context ctx = this.getApplicationContext();

Usually intents are tied to activity contexts not application contexts so I would check that.
