您好我正在尝试制作一个应用程序,该应用程序使用 listView 显示项目列表,并且当用户从列表中选择一个项目时。该应用程序将调用链接到所选项目的特定类,但是我在第二个@override 遇到错误,说覆盖必须覆盖超类。这是我的类和 xml 代码。
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageView
android:id="@+id/imageView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="@drawable/botanicgate" />
<ListView
android:id="@+id/listView"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
</LinearLayout>
package com.fyp.gulliver;
import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.TextView;
public class HotSpot extends ListActivity{
/** Called when the activity is first created. */
String places[] = {"BotanicGarden", "Sentosa"};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.hotspot);
ListView listView = (ListView) findViewById(R.id.listView);
listView.setAdapter(new ArrayAdapter
(HotSpot.this, android.R.layout.simple_list_item_1,
places));
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// TODO Auto-generated method stub
Class ourClass;
String item = ((TextView)view).getText().toString();
try {
ourClass = Class.forName
("com.fyp.gulliver." + item);
Intent ourIntent = new Intent(HotSpot.this, ourClass);
startActivity(ourIntent);
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
}
}
由于我还是 android 的新手,因此我不知道我犯了什么错误,如果其他人可以帮助我解决我的错误,我将不胜感激谢谢:D
