情况: 我已根据this question和related sample app on GitHub中的说明向Android中的联系人添加了自定义操作。按下时我想在我的应用程序中拨打该联系人。我能够成功检索按下自定义操作时打开的活动中的联系人。
我执行此操作:
Cursor cursor = context.getContentResolver().query(data, null, null, null, null);
if (cursor != null) {
newIntent = true;
contact = LocalContactAsync.getContacts(cursor, context.getContentResolver()).get(0);
cursor.close();
}
我从Android检索到的data
是:
内容://com.android.contacts/data/2849
注意最后的数字2849,这不是联系人的本机ID。联系人的本机ID为459
。我能够成功检索执行此查询的联系人,以下数据返回:
cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID);
-returns'''
cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)) ;
-returns'样品样品'这是正确的
但是,虽然这是真的:
cursor.getInt(cur.getColumnIndex(
ContactsContract.Contacts.HAS_PHONE_NUMBER)) > 0)
以下函数返回一个空光标:
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
new String[]{id}, null);
-id = 2849在这种情况下如果我填写459我检索到适量的电话号码
真正的联系人有3个号码,所以它应该返回3个号码。
我如何解决这个问题?
编辑:
这是我检索数字的方式,要明确:我得到了正确的名称,但是当联系人有数字时,以下查询会返回null
。
ArrayList<Number> numbers = new ArrayList<>();
if (cur.getInt(cur.getColumnIndex(
ContactsContract.Contacts.HAS_PHONE_NUMBER)) > 0) {
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
new String[]{id}, null);
while (pCur.moveToNext()) {
numbers.add(new nl.coffeeit.clearvoxnexxt.objects.dto.Number(pCur.getString(pCur.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.NUMBER))));
}
pCur.close();
}
return numbers;
请注意,我没有请求意图,我是通过添加到本机联系人的自定义操作收到的,例如Viber和WhatsApp:
完整代码LocalContacts Async:
private static final String TAG = "LocalContactAsync";
private static List<Contact> contacts;
private Context context;
private boolean refreshOtherFragments;
private boolean renew;
private synchronized List<Contact> getContacts(Context context) {
if (!renew && contacts != null) {
return contacts;
}
ContentResolver cr = context.getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
if (cur != null && cur.getCount() > 0) {
contacts = getContacts(cur, cr);
cur.close();
return contacts;
}
if (cur != null) {
cur.close();
}
return new ArrayList<>();
}
public static List<Contact> getContacts(Cursor cur, ContentResolver cr) {
List<Contact> contacts = new ArrayList<>();
while (cur.moveToNext()) {
String id = getId(cur);
String name = getName(cur);
ArrayList<Number> numbers = getNumbers(cur, cr, id);
if (name != null) {
contacts.add(new Contact(id, name, numbers));
}
}
Log.d(TAG, "amount of contacts" + contacts.size());
return contacts;
}
private static ArrayList<Number> getNumbers(Cursor cur, ContentResolver cr, String id) {
ArrayList<Number> numbers = new ArrayList<>();
if (cur.getInt(cur.getColumnIndex(
ContactsContract.Contacts.HAS_PHONE_NUMBER)) > 0) {
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
new String[]{id}, null);
while (pCur.moveToNext()) {
numbers.add(getNumber(pCur));
}
pCur.close();
}
return numbers;
}
private static Number getNumber(Cursor pCur) {
return new nl.coffeeit.clearvoxnexxt.objects.dto.Number(pCur.getString(pCur.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.NUMBER)));
}
private static String getId(Cursor cur) {
return cur.getString(
cur.getColumnIndex(ContactsContract.Contacts._ID));
}
private static String getName(Cursor cur) {
return cur.getString(cur.getColumnIndex(
ContactsContract.Contacts.DISPLAY_NAME));
}
编号DTO的代码:
public class Number implements Parcelable, Serializable {
@SerializedName("number")
@Expose
public String number;
@SerializedName("type")
@Expose
public String type = "";
@SerializedName("inherited")
@Expose
public Boolean inherited = false;
public Number(String number) {
this.number = number;
}
protected Number(Parcel in) {
number = in.readString();
type = in.readString();
byte inheritedVal = in.readByte();
inherited = inheritedVal == 0x02 ? null : inheritedVal != 0x00;
}
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(number);
dest.writeString(type);
if (inherited == null) {
dest.writeByte((byte) (0x02));
} else {
dest.writeByte((byte) (inherited ? 0x01 : 0x00));
}
}

}
@Override

return new Number[size];
}
};
public Number setNumber(String number) {
this.number = number;
return this;
}
}
答案 0 :(得分:1)
首先要注意的是对联系人选择器的调用如下:
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
会像这样返回一个Uri:
content://com.android.contacts/contacts/lookup/3163r328-4D2941473F314D2941473F3131/328
倒数第二个路径(3163r ....)是查找键,而328是NAME_RAW_ID
。
将此与您从sample application获得的意图进行比较。这包含一个看起来像这样的Uri:
content://com.android.contacts/data/2849
正如您所说,使用此Uri调用内容解析程序不足以检索电话号码,尽管它可能用于检索联系人姓名和ID。因此,我们将使用不完整的Intent Uri构建一个新的Lookup Uri,我们可以使用它来获取电话号码。
让我们将以下方法添加到您的LocalContactAsync(我不会重构您到目前为止所做的任何事情,我只会添加您使用的样式):
public static Uri getLookupUri(Cursor cur) {
return getContentUri(getLookupKey(cur), getNameRawId(cur));
}
private static String getLookupKey(Cursor cur) {
return cur.getString(
cur.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
}
private static String getNameRawId(Cursor cur) {
return cur.getString(cur.getColumnIndex(ContactsContract.Contacts.NAME_RAW_CONTACT_ID));
}
private static Uri getContentUri(String lookupKey, String nameRawId) {
return new Uri.Builder()
.scheme("content")
.authority("com.android.contacts")
.appendPath("contacts")
.appendPath("lookup")
.appendPath(lookupKey)
.appendPath(nameRawId)
.build();
}
让我们更改示例应用程序中的ViewingActivity
,以便它实际检索联系人详细信息。我们现在可以使用onResume()
中的以下代码执行此操作:
@Override
protected void onResume() {
super.onResume();
Uri uri = getIntent().getData();
Cursor intentCursor = this.getContentResolver().query(uri, null, null, null, null);
Contact contact = null;
if (intentCursor != null) {
intentCursor.moveToFirst();
Uri lookupUri = LocalContactAsync.getLookupUri(intentCursor);
Cursor lookupCursor = this.getContentResolver().query(lookupUri, null, null, null, null);
contact = LocalContactAsync.getContacts(lookupCursor, this.getContentResolver()).get(0);
intentCursor.close();
lookupCursor.close();
}
}
联系人现在将根据需要包含电话号码。
