私が読んだすべてのスレッドのすべての解決策を試しました。なにか提案を?
アプリケーションをデバッグしましたが、Android の内部コードに例外があり、行数がありません。
これがクラスです
package com.beppe.reminder;
import android.app.Activity;
import android.content.Context;
import android.database.Cursor;
import android.os.Bundle;
import android.widget.TextView;
public class ReminderShow extends Activity{
private Context mCtx;
private long ID;
private DBAdapter db;
private Cursor c;
ReminderShow(Context c){
mCtx=c;
}
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
db=new DBAdapter(mCtx);
setContentView(R.layout.reminder_show);
TextView tit=(TextView)findViewById(R.id.title11);
TextView bod=(TextView)findViewById(R.id.body11);
TextView dat=(TextView)findViewById(R.id.date11);
TextView tim=(TextView)findViewById(R.id.time11);
if(getIntent()!=null){
ID=getIntent().getExtras().getLong(DBAdapter.KEY_ROWID);
db.open();
c=db.fetchTaskById((int)ID);
c.moveToFirst();
tit.setText(c.getString(1));
bod.setText(c.getString(2));
dat.setText(c.getString(3).split(" ")[0]);
tim.setText(c.getString(3).split(" ")[1]);
}
}
}
そしてこれがマニフェストです
アクティビティは正しく宣言されており、パッケージから削除すると、コンパイラにエラーが表示されます。
