我一直在努力寻找并修复此错误。我不确定究竟是什么导致了错误,但是当我尝试运行这个类时我的应用程序崩溃了。我认为它可能与ListView或数组有关。
我的Java文件:
package com.example.ispoke;
import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class AustralianAnimalsMenu extends ListActivity{
String AusAnimalItm[] = {"Aus Animal 1", "Aus Animal 2", "Aus Animal 3", "Aus Animal 4", "Aus Animal 5"};
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_australiananimalsmenu);
setListAdapter(new ArrayAdapter<String>(AustralianAnimalsMenu.this, android.R.layout.activity_list_item, AusAnimalItm));
}
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
super.onListItemClick(l, v, position, id);
String selection = AusAnimalItm[position];
try{
Class<?> ourClass = Class.forName("com.example.ispoke." + selection);
Intent ourIntent = new Intent(AustralianAnimalsMenu.this, ourClass);
startActivity(ourIntent);
}catch(ClassNotFoundException ell){
ell.printStackTrace();
}
}
}
我的xml文件:
