安卓：设置联系人的照片在ListView有姓名和电话号码 [英] Android: Set contact photo in a ListView with name and number

问题描述

我创建一个应用程序，需要显示其照片，姓名和号码的电话联系。我创建了一个ListView和可以显示联系人和电话号码与一个普通的照片，但我不能显示contat的图片。这是我的code：

I'm creating an app that needs to display the phone contacts with its photo, name and number. I've created a ListView and can show contacts and numbers with a generic photo, but I can't show contat's picture. This is my code:

Cursor cursor = getContacts();

String[] fields = new String[] {Contacts.DISPLAY_NAME, Phone.NUMBER};

SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, R.layout.contact_entry, cursor,
            fields, new int[] {R.id.contactEntryText, R.id.contactEntryNumber});

mContactList.setAdapter(adapter);

private Cursor getContacts()

    // Run query
    Uri uri = Phone.CONTENT_URI;
    String[] projection = new String[] {
            Contacts._ID,
            Contacts.DISPLAY_NAME,
            Phone.NUMBER,
            Contacts.PHOTO_ID

    };
    //String selection = Contacts.HAS_PHONE_NUMBER + "='1'";
    String selection = null;
    String[] selectionArgs = null;
    String sortOrder = Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";

    return managedQuery(uri, projection, selection, selectionArgs, sortOrder);
}

我如何可以附加在SimpleCursorAdapter联系人的图片？难道还有其他的？

How can I attach the contact's picture in the SimpleCursorAdapter? Is there another?

非常感谢你。

推荐答案

我想它了。如果有人有同样的问题，我是这样做的：

I figured it out. If someone had the same problem, this is how i did it:

在扩展ListActivity的活动：

In an activity that extends ListActivity:

    @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Cursor names = getNamesAndPictures();
    names.moveToFirst();        
    ListAdapter adapter = new MySimpleCursorAdapter(this, R.layout.contacts,
                names, new String[] {Phones.NAME, Phones.NUMBER}, new int[] {
                R.id.Nombre, R.id.Numero});
    setListAdapter(adapter);
    startManagingCursor(names);
    Log.i(DEBUG_TAG, "Mi numero: " + miNumeroTelefono());        
}

public Cursor getNamesAndPictures(){
     String[] projection = new String[] {
             Phones.NUMBER,
             Phones.PERSON_ID,
             People.NAME,
             People._ID
     };
     String selection = Phones.NAME + "!='null'";
     String sortOrder = Phones.NAME + " COLLATE LOCALIZED ASC";
     Cursor cursor = managedQuery(Phones.CONTENT_URI, projection, selection, null, sortOrder);
     return cursor;
}

在自定义适配器：

public class MySimpleCursorAdapter extends SimpleCursorAdapter {

  ...

  @Override
  public void bindView(View view, Context context, Cursor cursor) {
      ImageView imageView = (ImageView) view.findViewById(R.id.Foto);

      int id = cursor.getColumnIndex(Phones.PERSON_ID);
      Uri uri = ContentUris.withAppendedId(Phones.CONTENT_URI, cursor.getLong(id));
      String uriPhoto = uri.toString();
      String uriPeople = uriPhoto.replace("phones", "people");

      Uri uriFinal = Uri.parse(uriPeople);

      Bitmap bitmap = People.loadContactPhoto(context, uriFinal, R.drawable.avatar02, null);
      imageView.setImageBitmap(bitmap);
      super.bindView(view, context, cursor);
  }
}
