Question

我在google和stackoverflow上看了很多，最后写了一些代码，我认为应该按预期将联系人放到listview中。但我总是得到这个错误。谁能帮我？

这是我的主要课程：

package com.shoaiblalich.pinchme;

import java.util.ArrayList;

import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.provider.ContactsContract.RawContacts;
import android.app.Activity;
import android.database.Cursor;
import android.view.Menu;
import android.widget.ListView;
import android.widget.SimpleCursorAdapter;

public class Main extends Activity {



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    populateContactList();
}




private void populateContactList() {
    // TODO Auto-generated method stub
    Cursor cur = getContacts();
    String[] fields = new String[] {ContactsContract.Data.DISPLAY_NAME};
    SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,android.R.layout.simple_list_item_1,cur,fields,new int[] {android.R.id.text1});;
    ListView lv = (ListView) findViewById(R.id.listView1);
    lv.setAdapter(adapter);   

}




@SuppressWarnings("deprecation")
private Cursor getContacts() {
    // TODO Auto-generated method stub
    Uri uri = ContactsContract.Contacts.CONTENT_URI;
    String [] projection = new String[] {
            ContactsContract.Contacts._ID,
            ContactsContract.Contacts.DISPLAY_NAME };
    String selection = null;
    String[] selectionArgs = null;
    String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + "COLLATE LOCALIZED ASC";
    return managedQuery(uri,projection,selection,selectionArgs,sortOrder);

}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

}

这就是我的logCat显示的内容：

我真的很难将联系人放到列表视图中。如果我的问题太混乱，有人可以告诉我如何从头开始这样做吗？

Answer 1

由于错误非常明显是语法错误，display_name中的ORDER BY display_nameCOLLATE LOCALIZED ASC后空格丢失了

替换如下

String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";

android：麻烦用联系人填充listview
