私はプログラミングを始めたばかりで、スウェーデンの法律書の Android バージョンを作成しています。コードにエラーはありませんが、エミュレーターで実行しようとすると起動しますが、ボタンを押すとすぐに「残念ながら、アプリの名前が停止しました」と表示されます。
私はこのような他の多くのスレッドを調べましたが、それらはすべてコード固有のものであり、したがって私には役に立ちません.
私はエクリプスを使用しています。
それで、親切な魂が私がしたことを見て間違いを見つけるのを助けることができるかどうか疑問に思っていましたか?
これは「Activity_Main_activity.xml」のコーディングです。
<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" />
ご覧のとおり、非常にシンプルです。
MainActivity.java コーディングは次のとおりです。
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);
編集: LogCat を追加しました。これが必要だとは知りませんでした、ごめんなさい！

「メイン アクティビティ」の名前を「Huvud Meny」に変更しました。
私はそれが意図（天才）に何か問題があるに違いないと考えましたが、それが何であるかはわかりません。
誰かが時間を割いて私を助けてくれたら、私はとても幸せです！
