Q&A线程很多,但它们都没有提供真正的答案,或者我找不到它。
为了确保你,我在问:
那么,有谁知道如何使用意图(如示例代码)并插入位图中的照片呢?
我现在确实使用了示例代码来启动对话框,以便用户在保存之前允许他插入或取消并可能编辑字段:
// PrivateContactClass c;
// Bitmap photo;
Intent inOrUp = new Intent(ContactsContract.Intents.Insert.ACTION, ContactsContract.Contacts.CONTENT_URI);
inOrUp.setType(ContactsContract.Contacts.CONTENT_TYPE);
inOrUp.putExtra(ContactsContract.Intents.Insert.NAME, ModelUtils.formatName(c));
inOrUp.putExtra(ContactsContract.Intents.Insert.PHONE, getPrimaryPhone());
inOrUp.putExtra(ContactsContract.Intents.Insert.TERTIARY_PHONE, c.getMobile());
inOrUp.putExtra(ContactsContract.Intents.Insert.EMAIL, c.getMail());
inOrUp.putExtra(ContactsContract.Intents.Insert.JOB_TITLE, c.getFunction());
inOrUp.putExtra(ContactsContract.Intents.Insert.NOTES, getSummary());
inOrUp.putExtra(ContactsContract.Data.IS_SUPER_PRIMARY, 1);
startActivity(inOrUp);我找到了解决办法,多亏了朱利安的回答
不只是使用意图,因为我怀疑我们是否能够传递由数据ContentProvider保存的图像的ID,或者在意向中直接传递位图。
扩展自上面的代码
使用带有常量请求代码的startActivityForResult
// must be declared in class-context
private static final int CONTACT_SAVE_INTENT_REQUEST = 1;
...
startActivityForResult(inOrUp,CONTACT_SAVE_INTENT_REQUEST);添加根据意图启动的活动的处理结果。
@Override
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
switch (requestCode) {
case RESULT_INSERT_CONTACT:
if (resultCode == RESULT_OK) {
trySetPhoto();
}
break;
}
}添加方法设置照片
public boolean setDisplayPhotoByRawContactId(long rawContactId, Bitmap bmp) {
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
Uri pictureUri = Uri.withAppendedPath(ContentUris.withAppendedId(RawContacts.CONTENT_URI,
rawContactId), RawContacts.DisplayPhoto.CONTENT_DIRECTORY);
try {
AssetFileDescriptor afd = getContentResolver().openAssetFileDescriptor(pictureUri, "rw");
OutputStream os = afd.createOutputStream();
os.write(byteArray);
os.close();
afd.close();
return true;
} catch (IOException e) {
e.printStackTrace();
}
return false;
}添加方法以搜索联系人并添加联系人照片
private void trySetPhoto() {
// Everything is covered in try-catch, as this method can fail on
// low-memory or few NPE
try {
// We must have an phone identifier by which we search for
// format of phone number is not relevant, as ContentProvider will
// normalize it automatically
if (c.getMobile() != null) {
Uri lookup = Uri.withAppendedPath(
ContactsContract.PhoneLookup.CONTENT_FILTER_URI,
Uri.encode(c.getMobile()));
Cursor c = getContentResolver().query(lookup, null, null, null,
null);
// Remember cursor can be null in some cases
if (c != null) {
// we can obtain bitmap just once
Bitmap photo_bitmap = getPhotoBitmap();
c.moveToFirst();
// if there are multiple raw contacts, we want to set the photo for all of them
while (c.moveToNext()) {
setDisplayPhotoByRawContactId(
c.getLong(c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.RAW_CONTACT_ID)),
photo_bitmap);
}
// remember to clean up after using cursor
c.close();
}
}
} catch (Exception e) {
// Logging procedures
} catch (Error e) {
// Logging procedures
}

为了帮助您,我找到了原始文档:http://java.llp2.dcc.ufmg.br/apiminer/docs/reference/android/provider/ContactsContract.RawContacts.DisplayPhoto.html
阅读以下内容:http://java.llp2.dcc.ufmg.br/apiminer/docs/reference/android/provider/ContactsContract.RawContacts.html
对我来说,一个简单的解决方案是,如果您的代码可以调用:
startActivityForResult(inOrUp, CODE_INSERT_CONTACT);然后在"onActivityResult“中调用”setDisplayPhotoByRawContactId“:
/** @return true if picture was changed false otherwise. */
public boolean setDisplayPhotoByRawContactId(long rawContactId, Bitmap bmp) {
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
Uri pictureUri = Uri.withAppendedPath(ContentUris.withAppendedId(RawContacts.CONTENT_URI,
rawContactId), RawContacts.DisplayPhoto.CONTENT_DIRECTORY);
try {
AssetFileDescriptor afd = getContentResolver().openAssetFileDescriptor(pictureUri, "rw");
OutputStream os = afd.createOutputStream();
os.write(byteArray);
os.close();
afd.close();
return true;
} catch (IOException e) {
e.printStackTrace();
}
return false;
}通常,这段代码来自API的第14版。我不得不对这个话题做研究。
您可以获得rawContactId,如文档中所示:
Uri rawContactUri = RawContacts.URI.buildUpon()
.appendQueryParameter(RawContacts.ACCOUNT_NAME, accountName)
.appendQueryParameter(RawContacts.ACCOUNT_TYPE, accountType)
.build();
long rawContactId = ContentUris.parseId(rawContactUri);我不确定但这些文件会对你有帮助的。对不起我的英语。

被接受的答案不符合问题的要求。
请参阅@yeo100 100的回答,它使用ContactsContract.Intents.Insert.DATA (文档 -有点模糊,很难找到:/),因为联系人照片保存在数据表中的特定类型:
Data.MIMETYPE -> ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE
这对我来说很管用,而且更整洁,更容易管理。
