我是android开发的新手。按下图像按钮后，我一直在尝试开始新的活动。但是当我尝试在模拟器中运行它时，我总是得到一个错误：“ AppName已停止”。

这是我的代码： 图片按钮：

 <ImageButton
        android:id="@+id/FirstAidButton"
        android:layout_width="80dp"
        android:layout_height="80dp"
        android:layout_toLeftOf="@+id/BodyMassIndex"
        android:background="@null"
        android:contentDescription="@string/firstaid"
        android:src="@drawable/firstaid" 
        android:onClick="fatTutorial" />

爪哇：

public void fatTutorial(View view) {
        Intent intent = new Intent(this, FirstAidTutorial.class);

        startActivity(intent);
    }

显现：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="dr.droid"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="15" />

<application
    android:icon="@drawable/drdroid"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".Home"
        android:label="@string/title_activity_home" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
   <activity android:label="@string/title_text" android:name="dr.droid.FirstAidTutorial"/>

   </application>

</manifest>

接收类（FirstAidTutorial）：

    @Override
    public void onCreate(Bundle savedInstanceState) {
        Intent intent = getIntent();
    }

有任何想法吗？而且，我如何为该新活动创建一个 xml，以便我可以将设计/布局放入其中。谢谢！

在清单文件中声明FirstAidTutorialActivity。

<activity android:label="@string/title_text" android:name=".FirstAidTutorial"/>

如何为该新活动创建一个 xml，以便我可以将设计/布局放入其中。

首先在 res -> layout 文件夹中创建一个 xml 文件，然后在 FirstAidTutorial Activity 中使用setContentView(R.layout.yourlayout);.

public class FirstAidTutorial extends Activity {

    @Override
    public void onCreate(Bundle icicle) {

        super.onCreate(icicle);

        setContentView(R.layout.yourlayout);

    }
}

像这样在清单中声明 FirstAidTutorial。您的包裹应以“com”开头。

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.dr.droid"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />

<application
android:icon="@drawable/drdroid"
android:label="@string/app_name"
android:theme="@style/AppTheme" >


 <activity
    android:name=".Home"
    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=".FirstAidTutorial"
    android:label="@string/app_name" >
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

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

   </application>
