在 imageview 中显示联系人图片。

【问题标题】：Displaying a contacts picture in imageview.在 imageview 中显示联系人图片。

【问题描述】：

我使用以下查询联系人的图片：

Uri phUri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_URI,String.valueOf(contactId));

结果我得到了类似的东西：

content://com.android.contacts/contacts/3699

然后我尝试将其设置为图像视图：

Uri IMAGE_URI = Uri.parse(image);
                IMAGE_URI= Uri.withAppendedPath(IMAGE_URI, Contacts.Photo.CONTENT_DIRECTORY);
                try{
                    ((ImageView) view.getTag(R.id.imageView1)).setImageURI(IMAGE_URI);

                }catch (Exception e){
                    System.out.println(e);
                }

它引发了一个找不到文件的异常，但是 catch 块中的 System.out.println() 会打印一个错误的位图 uri。上面的代码几天前可以正常工作，不知道出了什么问题。

【问题讨论】：

  • 请关注github.com/loopj/android-smart-image-view
  • Contacts.Photo.CONTENT_DIRECTORY 自 API 级别 5 以来已被弃用，不明白你为什么要使用它。在此处查看openContactPhotoInputStream：developer.android.com/reference/android/provider/… 并可能在使用上面收到的输入流的 BitmapFactory.decodeStream 将其设置为 imageView 之前解码图像
  • IDE 没有给我一个折旧警告，所以我不知道。不过我好像发现了问题。我隔离了问题代码，并且确实返回值不同我以某种方式在问题项目中获得了修剪结果。现在我正试图衡量为什么会这样。

【解决方案1】：

您拥有的 Uri 不是确切的文件，使用该 ID，您应该使用 managedQuery 检索图像

想法会是这样的

private void setContactInfo(long id){
Bitmap photoBitmap = null;
Uri contactUri = ContentUris.withAppendedId(
        ContactsContract.Contacts.CONTENT_URI, id);

Cursor cursor = managedQuery(contactUri, null, null, null, null);
cursor.moveToFirst();
contact_text.setText(cursor.getString(cursor
        .getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)));//contact.text is a     textView used to displays the contact name

String id = getIntent().getData().getLastPathSegment();
// Photo cursor

String photoWhere = ContactsContract.Data.CONTACT_ID + " = ? AND "
        + ContactsContract.Data.MIMETYPE + " = ?";
String[] photoWhereParams = new String[] { id,
        ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE };
Cursor photoCur = managedQuery(ContactsContract.Data.CONTENT_URI, null,
        photoWhere, photoWhereParams, null);
photoCur.moveToFirst();
if (photoCur.moveToFirst() && photoCur != null) {

    byte[] photoBlob = photoCur.getBlob(photoCur
            .getColumnIndex(Photo.PHOTO));
    if (photoBlob != null) {
        photoBitmap = BitmapFactory.decodeByteArray(photoBlob, 0,
                photoBlob.length);

        contact_image.setImageBitmap(photoBitmap);//contact_image is an ImageView
    } else {
        photoBitmap = BitmapFactory.decodeResource(getResources(),
                 android.R.drawable.ic_menu_report_image);//android.R.drawable.ic_menu_report_image is the default image if a Contact doesn't have any image stored
        contact_image.setImageBitmap(photoBitmap);
    }

}
cursor.close;
photoCur.close;         

}

【讨论】：

  • 这让我很吃惊，因为代码在一段时间前就可以工作了！
  • 我没有尝试过，但我曾使用类似的 id 和媒体查询从图库中检索图像
  • 在解析重复的变量名称后，在String id = getIntent().getData().getLastPathSegment(); 给我一个 NPE。
  • 而不是 getIntent 使用你在 onActivity Result 中获得的意图
  • 关于managedQuery：此方法在 API 级别 11 中已弃用。请改用CursorLoader。
