Question

当我在Android 2.1中运行程序时。我收到错误应用程序意外停止然后强制关闭。我一次又一次清理项目然后构建但问题仍然存在。此程序需要显示电子邮件地址 ListView上模拟器的所有联系人。

码

public class Trial3 extends Activity {

ListView lvItem;
private Button btnAdd;
String displayName="", emailAddress="", phoneNumber="";
ArrayList<String> contactlist=new ArrayList<String>();
ArrayAdapter<String> itemAdapter;


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
   lvItem = (ListView)this.findViewById(R.id.listview);  
   btnAdd = (Button)this.findViewById(R.id.btn);
   itemAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,contactlist);
   lvItem.setAdapter(itemAdapter);
   btnAdd.setOnClickListener(new View.OnClickListener() {
       public void onClick(View v) {
           GetEmails();
           Toast.makeText(Trial3.this, "working...", Toast.LENGTH_SHORT).show();
       }
   }); 
}

private void GetEmails()
{
    ContentResolver cr =getContentResolver();
    Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
    while (cursor.moveToNext()) 
    {       
        String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
        Cursor emails = cr.query(Email.CONTENT_URI,null,Email.CONTACT_ID + " = " + id, null, null);
        while (emails.moveToNext()) 
        {               
            emailAddress = emails.getString(emails.getColumnIndex(Email.DATA));
            contactlist.add(emailAddress);
            itemAdapter.notifyDataSetChanged();
        }
        emails.close();

    }
    cursor.close(); 
}
}

如何解决这个问题？

Answer 1

添加权限以将联系人数据读取到您的应用程序清单中：

<uses-permission android:name="android.permission.READ_CONTACTS"/>

Answer 2

缺少权限

添加清单

<uses-permission android:name="android.permission.READ_CONTACTS"/>

Answer 3

获取android权限

<uses-permission android:name="android.permission.READ_CONTACTS"/>

在<manifest>之前的AndroidManifest.xml文件上。

Answer 4

在清单中添加权限

<uses-permission android:name="android.permission.READ_CONTACTS"/>
