android - RunTimeException android

Question

My android app gives me this error from logcat:

Caused by: java.lang.RunTimeException: Your content must have a ListView whose id attribute is 'android.R.id.list'

this is my code:

package com.WNF;

import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.app.ListActivity;
import android.content.Intent;


public class Actiemenu extends ListActivity{

@Override 
public void onCreate(Bundle savedInstanceState) { 

super.onCreate(savedInstanceState); 
setContentView (R.layout.actiemenu);

final String[] array = new String[] {
        "Ding", "AnderDing", "Nogeending", "laatseding"
    };

setListAdapter(new ArrayAdapter<String> (this, R.layout.actiemenu, array));
    ListView lv = getListView();
    lv.setTextFilterEnabled(true);



lv.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View v, int position, long id) {

        if (position == 0) {
            Intent een = new Intent(v.getContext(), Acties.class);
            startActivity(een);
        }
        else if (position == 1) {
            Intent twee = new Intent(v.getContext(), Acties2.class);
            startActivity(twee);
        }
    }
});
getIntent();
}
}

Any ideas what can be the problem??

Answer 1

将id 放入ListView您main.xml的

<ListView
android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>

Answer 2

导入这个

import your.package.name.R

在你的情况下：

import com.WNF.R

导入时出现此问题

android.R

代替

package.name.R;
