我正在尝试做一个使用标签的应用程序。我遵循这个教程：http: //mobileorchard.com/android-app-development-tabbed-activities/

我成功地使用一项活动完成了一个选项卡，但我的问题是当我尝试使用一些活动来完成该部分时。

我从android开始，你能帮帮我吗？你能说我用的方法好不好？（对不起我的英语^^）

在应用程序意外停止之前，我遇到了错误：

我的 tab_manage.xml：

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

<TabHost android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:id="@android:id/tabhost"
    xmlns:android="http://schemas.android.com/apk/res/android">
    <TabWidget
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@android:id/tabs"/>
    <FrameLayout
        android:id="@android:id/tabcontent"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
    </FrameLayout>
</TabHost>

我的 tabManage.java：它应该将我的 accueil_mobile 活动“放在”第一个选项卡中，并将标识放在

package com.example.joignabilite;

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

@SuppressWarnings("deprecation")
public class TabManage extends TabActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.tab_manage);

        TabHost tabHost=(TabHost)findViewById(android.R.id.tabhost);
        tabHost.setup();   

        //First Tab
        TabSpec spec1=tabHost.newTabSpec("Mobile");
        Intent in1=new Intent(this, AccueilMobile.class);
        spec1.setContent(in1);
        // Second Tab
        TabSpec spec2=tabHost.newTabSpec("Fixe");
        Intent in2=new Intent(this, Identification.class);
        spec2.setContent(in2);

        tabHost.addTab(spec1);
        tabHost.addTab(spec2);
    }
}

我的 accueil_mobile.xml：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

    tools:context=".Identification" >

    <include android:id="@+id/header"
         layout="@layout/header"
         android:layout_height="wrap_content"
         android:layout_width="fill_parent"/>

    <Button android:id="@+id/choix_transfert"
        android:layout_width="@dimen/button_width"
        android:layout_height="@dimen/button_height"
        android:layout_below="@+id/header"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="80dp"
        android:background="@drawable/buttontype1"
        android:text="@string/Transfert" />
    <Button android:id="@+id/choix_filtrage"
        android:layout_width="@dimen/button_width"
        android:layout_height="@dimen/button_height"
        android:layout_below="@+id/header"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="160dp"
        android:background="@drawable/buttontype1"

        android:layout_height="@dimen/button_height"
        android:layout_below="@+id/header"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="240dp"
        android:background="@drawable/buttontype1"
        android:text="@string/Parametres" />

</RelativeLayout>

我的 AccueilMobile.java：

package com.example.joignabilite;

import android.app.Activity;
import android.os.Bundle;

public class AccueilMobile extends Activity{

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.accueil_mobile);

    }
}

答案在堆栈跟踪的第二行。您显然还没有在 AndroidManifest.xml 中定义您的 Activity
