刚开始着手入门android,照着编的Sudiku程序,却出现错误,求解~
manifest中注册about activity不成功,还是无法运行about
manifest。xml如下:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.example.sudoku"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" /> <application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".Sudoku"
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=".About"></activity>
</application>
</manifest>和没有注册前一样出现The application Sudoku has stopped unexpectedly,please try again.发愁了好久,照着例子写的却出错了~~~~~~坐等解答

package org.example.sudoku;
import android.app.Activity;
import android.os.Bundle;public class About extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.about);
}}
下面的是About.xml
<?xml version="1.0" encoding="UTF-8"?>
<Scrollview
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dip">
<Textview
android:id="@+d/about_content"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/about_text"/>
</Scrollview>
最后是main.xml文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:background="@color/background"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="30dip"
android:orientation="horizontal">
<LinearLayout
android:orientation="vertical"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_gravity="center">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/main_title"
android:layout_gravity="center"
android:layout_marginBottom="25dip"
android:textSize="24.5sp"/>
<Button
android:id="@+id/continue_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/continue_label"/>
<Button
android:id="@+id/new_game_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/new_game_label"/>
<Button
android:id="@+id/about_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/about_label"/>
<Button
android:id="@+id/exit_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/exit_label"/> </LinearLayout>
</LinearLayout>
在编译的时候没有提示出错啊??就是运行不出来~~
