对于我的应用程序,我从ContactsContract API中读取了联系人的照片,该照片在Android KitKat之前运行良好。我找不到有关4.4更改日志中ContactsContract.Contacts.openContactPhotoInputStream()方法更改的具体内容,但我只能在KitKat上复制此内容,并且当该联系人没有照片时。
我使用以下内容阅读了联系人:
public static Bitmap getContactPhoto(final Uri lookupUri, final Context context, boolean preferHighRes)
throws IOException, OutOfMemoryError, NullPointerException{
InputStream photo_stream = ContactsContract.Contacts.openContactPhotoInputStream(context.getContentResolver(),
lookupUri, preferHighRes);
BufferedInputStream input = new BufferedInputStream(photo_stream);
Bitmap contactImg = BitmapFactory.decodeStream(input);
input.close();
return contactImg;
}
此方法的调用如下:
private class retrieveContactPhoto extends AsyncTask<Void, Void, Bitmap> {
Uri contactUri;
ImageView imageView;
public retrieveContactPhoto(Uri contactUri, ImageView iView){
this.contactUri = contactUri;
this.imageView = iView;
}
@Override
protected void onPreExecute(){
imageView.setImageResource(R.drawable.friend_image_default);
}
@Override
protected Bitmap doInBackground(Void... params) {
Bitmap image;
try {
image = ContactLookup.getContactPhoto(contactUri, mContext, true);
} catch (Exception e) {
image = null;
}
return image;
}
@Override
protected void onPostExecute(Bitmap image) {
if(image!=null){
imageView.setImageBitmap(image);
}
}
}
这将会持续几秒钟,但之后我会在LogCat中感到非常悲伤(通常超过50万行错误!?)

我不确定为什么它现在说关闭流,因为这不会发生在任何其他版本的Android上。此外,如果它不在工作线程中,则仍会出现此错误。

您可以尝试对代码进行一些小改动吗?我遇到了类似的问题 - 我的应用只是停留在无限循环中。
试试这个:
InputStream photo_stream = ContactsContract.Contacts.openContactPhotoInputStream((ContentResolver) getContentResolver().query(ContactData, null, null, null, null),lookupUri, preferHighRes);
这对我有用。

如果未设置联系人和照片,则必须使用默认联系人照片,您可以通过此路径找到该照片:
