Android 2.3和Android 4.0上的联系人照片uri

我的代码有问题。我需要获取联系人照片uri，并在ImageView中显示图片。我写了这段代码，它在Android2.3中正常工作

Uri myUri = getPhotoUriById( this, contactId );
(ImageView)myImageView.setImageUri( myUri );

public static Uri getPhotoUriById( Context context, Long id ) {
    if( id == null || context == null ) return null;

    Uri photo = Uri.parse( "android.resource://"+ context.getPackageName() +"/" + R.drawable.no_photo );

    Cursor cursor = context.getContentResolver().query( Contacts.CONTENT_URI,
            new String[]{ Contacts.PHOTO_ID },
            Contacts._ID + " = " + id + " AND " + Contacts.PHOTO_ID + " != 0",
            null,
            null );
    if( cursor != null ) {
        if( cursor.moveToFirst()) {
            photo = ContentUris.withAppendedId( Contacts.CONTENT_URI, id );
            photo = Uri.withAppendedPath( photo, Contacts.Photo.CONTENT_DIRECTORY );
        }
        cursor.close();
    }
    return photo;
}

但当我在安卓4.0（ICS）上测试它时。我有很多问题

我的错误在哪里？

几天后，我写了正确的代码。这适用于所有android版本。 这是我的解决办法

public static Uri getPhotoUriById( Context context, Long id ) {
    if( id == null || context == null ) return null;

    Uri photo = Uri.parse( "android.resource://"+ context.getPackageName() +"/" + R.drawable.no_photo );

    try {
        Cursor cursor = context.getContentResolver().query( Contacts.CONTENT_URI,
                new String[]{ Contacts.PHOTO_ID, "photo_uri" },
                Contacts._ID + " = " + id + " AND " + Contacts.PHOTO_ID + " != 0",
                null,
                null );
        if( cursor == null )
            return photo;
        if( !cursor.moveToFirst()) {
            cursor.close();
            return photo;
        }
        String sUri;
        if(( sUri = cursor.getString( cursor.getColumnIndex( "photo_uri" ))) != null ) {
            cursor.close();                                                         // content://com.android.contacts/display_photo/1
            return Uri.parse( sUri );
        }
        cursor.close();
        return photo;
    } catch( Exception e ) {
        Cursor cursor = context.getContentResolver().query( Contacts.CONTENT_URI,
                new String[]{ Contacts.PHOTO_ID },
                Contacts._ID + " = " + id + " AND " + Contacts.PHOTO_ID + " != 0",
                null,
                null );
        if( cursor == null )
            return photo;
        if( !cursor.moveToFirst()) {
            cursor.close();
            return photo;
        }
        cursor.close();
        photo = ContentUris.withAppendedId( Contacts.CONTENT_URI, id );
        photo = Uri.withAppendedPath( photo, Contacts.Photo.CONTENT_DIRECTORY );
        return photo;
    }
}

“photo_uri”是一个常量Contacts.photo_uri，它是从API级别11添加的。

原始答案运行良好，但我认为它可以改进很多。我看不出try/catch有什么必要，因为您可以只使用底部部分的代码，而底部部分没有折旧方法。这支持API级别10-19（可能低于该级别，但我从未检查过）。这就是我的目的

    Uri photo = ContentUris.withAppendedId( ContactsContract.Contacts.CONTENT_URI, id);
    photo = Uri.withAppendedPath( photo, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY );
    Bitmap bitmap =  MediaStore.Images.Media.getBitmap(contentResolver, photo);

如果没有照片，它将抛出异常

您找到答案了吗？如果你发现它，请分享它，因为我面临着同样的问题嗨，我有一个问题，这段代码时，我在使用，它给了我坏的URI在ICS安卓版在正文中的尝试。任何解决方案或者我遗漏了什么？正如你所说的“photo_uri”是从API级别11添加的，那么它将如何在android应用程序支持2.2中使用呢？我正在为同步联系人映像获取不同的URI，如content://com.android.contacts/contacts/271/photo 因此，它没有给出任何图像作为回报，而是给出了异常，正如我上面所说的那样。@RushabhPatel catch（）块在具有API 10及更低版本的设备上工作，因为getContentResolver（）.query（）会给出异常，在这种情况下，这个函数返回content://com.android.contacts/contacts/251/photo.@RushabhPatel如果您在API 11及更高版本的设备上测试它，可能另一行代码会给您一个异常。那么，我想，您将无法获得正确的URI。那么，哪一行给了你一个例外？
