我刚刚开始编程，正在制作瑞典法律书籍的安卓版本。我的代码没有错误，但是当我尝试在模拟器中运行它时，它会启动，但只要按下一个按钮，它就会显示“不幸的是，应用程序的名称已停止。”
我查看了许多其他类似的线程，但它们都是特定于代码的，因此对我没有用。
我正在使用 Eclipse。
所以，我想知道是否有任何善良的灵魂可以通过我所做的事情来帮助我找到错误？
这是“Activity_Main_activity.xml”编码：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".HuvudMeny" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:text="Kapitel 1, Om Brott och Brottspåföljder"
android:onClick = "kapett" />
如您所见，它非常简单。
这是 MainActivity.java 编码：
import com.example.brottsbalken.Kap1;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
public class HuvudMeny extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_huvud_meny);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_huvud_meny, menu);
return true;
}
public void kapett(View view) {
Intent intent1 = new Intent(this, Kap1.class);
startActivity(intent1);
编辑：添加了 LogCat。不知道你需要这个，对不起！

我将“主要活动”的名称更改为“Huvud Meny”。
我想这一定是意图（天才）有问题，但我不知道它是什么。
如果有人花时间帮助我，我会非常高兴！
