Question

可能重复：
How do I display a contact's photo from the contact's id?

我一直在尝试用我的设备中的联系人照片在我的ListView中填充我的ImageViews，但无济于事。

是否有 COMPLETE解决方案为 API Level 10 执行此操作？

我的LogCat代码：

Why are my contact photos not displaying in listview?

** CustomAdapter类：**

public class CustomAdapter extends ArrayAdapter<String> {

        Cursor c;
        String TAG = "CustomAdapter";
        private Context context = null;
        ArrayList<String> elements = null;
        private ArrayList<String> data = null;

        public static String contactName;
        public static int count = 0;

        private ArrayList<Boolean> itemChecked = null;
        public static List<String> messages;
        public static List<String> contactID;

        String body;
        String phoneNumber;

        public CustomAdapter(Context context, int type, ArrayList<String> elements) {
                super(context, type, elements);

                data = elements;
                this.elements = elements;
                this.context = context;
        }

        // THIS IS SIMPLY A CLASS VIEW WILL HOLD DIFFERENT VIEWS OF YOUR ROW.

Answer 1

使用此代码从联系人中获取照片...........

public static Bitmap loadContactPhoto(ContentResolver cr, long id) {
Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, id);
InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(cr, uri);
// InputStream input = ContactsContract.Contacts.Photo
if (input == null) {
    return null;
}
return BitmapFactory.decodeStream(input);

将此内容写在您想要的地方的代码段中

// set the profile picture
ImageView profile = (ImageView) findViewById(R.id.display_contact_image);
Bitmap bitmap = loadContactPhoto(getContentResolver(), _id);
if(bitmap == null) {
    //Set default contact image
    profile.setImageResource(R.drawable.default_contact_image);
} else {
    profile.setImageBitmap(bitmap);
}

方法是

private static Bitmap loadContactPhoto(ContentResolver cr, long  id) {
    Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, id);
    InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(cr, uri);
    if (input == null) {
        return null;
    }
    return BitmapFactory.decodeStream(input);
}

并分享您尝试过的代码....（从上一周开始：）

是否有一个解决方案，用2.3的联系人照片填充列表视图？
