我想向特定用户拨打 WhatsApp 电话。我试过了,但不起作用:
Uri uri = Uri.parse("callto:" + phoneNUmber);
Intent i = new Intent(Intent.ACTION_CALL, uri);
i.setPackage("com.whatsapp");
startActivity(i);
我知道如何创建 WhatsApp 消息,代码类似并且有效:
Uri uri = Uri.parse("smsto:" + phoneNUmber);
Intent i = new Intent(Intent.ACTION_SENDTO, uri);
i.setPackage("com.whatsapp");
startActivity(i);
简单的解决方案是,查询 ContactContract.Data 的 _id 和 MIME 类型。
ContentResolver resolver = context.getContentResolver();
cursor = resolver.query(
ContactsContract.Data.CONTENT_URI,
null, null, null,
ContactsContract.Contacts.DISPLAY_NAME);
//Now read data from cursor like
while (cursor.moveToNext()) {
long _id = cursor.getLong(cursor.getColumnIndex(ContactsContract.Data._ID));
String displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
String mimeType = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.MIMETYPE));
Log.d("Data", _id+ " "+ displayName + " " + mimeType );
}
输出将如下所示
12561 雪 vnd.android.cursor.item/vnd.com.whatsapp.profile
12562雪vnd.android.cursor.item/vnd.com.whatsapp.voip.call
现在仅将 MIME 类型为
vnd.android.cursor.item/vnd.com.whatsapp.voip.call
的 _Id 保存在数据库或其他地方
然后您可以像这样与这些联系人发起 Whatsapp 通话
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
// the _ids you save goes here at the end of /data/12562
intent.setDataAndType(Uri.parse("content://com.android.contacts/data/_id"),
"vnd.android.cursor.item/vnd.com.whatsapp.voip.call");
intent.setPackage("com.whatsapp");
startActivity(intent);
要进行 WhatsApp 视频通话,请使用以下 mime 字符串:
String mimeString = "vnd.android.cursor.item/vnd.com.whatsapp.video.call";
要进行 WhatsApp 语音通话,请使用以下 mime 字符串:
String mimeString = "vnd.android.cursor.item/vnd.com.whatsapp.voip.call";
使用以下代码:
String displayName = null;
String name="ABC" // here you can give static name.
Long _id;
ContentResolver resolver = getApplicationContext().getContentResolver();
cursor = resolver.query(ContactsContract.Data.CONTENT_URI, null, null, null, ContactsContract.Contacts.DISPLAY_NAME);
while (cursor.moveToNext()) {
_id = cursor.getLong(cursor.getColumnIndex(ContactsContract.Data._ID));
displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
String mimeType = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.MIMETYPE));
if (displayName.equals(name)) {
if (mimeType.equals(mimeString)) {
String data = "content://com.android.contacts/data/" + _id;
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_VIEW);
sendIntent.setDataAndType(Uri.parse(data), mimeString);
sendIntent.setPackage("com.whatsapp");
startActivity(sendIntent);
}
}
}
此代码是检查号码是否有whatsapp并进行whatsapp音频和视频通话
首先检查号码是否有whatsapp...如果你不知道
if rowContactId (return type of hasWhatsapp) is not equal to '0' then this number has whatsapp.
.
public String hasWhatsapp( getContactIDFromNumber(795486179).toString(),MAinactivity.this )
{
String rowContactId = null;
boolean hasWhatsApp;
String[] projection = new String[]{ContactsContract.RawContacts._ID};
String selection = ContactsContract.Data.CONTACT_ID + " = ? AND account_type IN (?)";
String[] selectionArgs = new String[]{contactID, "com.whatsapp"};
Cursor cursor = getContentResolver().query(ContactsContract.RawContacts.CONTENT_URI, projection, selection, selectionArgs, null);
if (cursor != null) {
hasWhatsApp = cursor.moveToNext();
if (hasWhatsApp) {
rowContactId = cursor.getString(0);
}
cursor.close();
}
return rowContactId;
}
public static int getContactIDFromNumber( contactNumber,Context context)

{
phoneContactID = contactLookupCursor.getInt(contactLookupCursor.getColumnIndexOrThrow(ContactsContract.PhoneLookup._ID));
}
contactLookupCursor.close();
return phoneContactID;

如果我们传递 rawContactId,那么我们可以使用它来直接获取与 Whatsapp 呼叫 URI 关联的 ID。
private void whatsAppCall(Context context, String rawContactId) {
try {
int id = whatsAppCallId(context, rawContactId);
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
String uriString = "content://com.android.contacts/data/" + id;
intent.setDataAndType(Uri.parse(uriString), "vnd.android.cursor.item/vnd.com.whatsapp.voip.call");
intent.setPackage("com.whatsapp");
startActivity(intent);
} catch (Exception e) {
Log.e(TAG, "whatsAppCall Exception: " + e);
}
}
private long whatsAppCallId(Context context, String rawContactId){
ContentResolver resolver = context.getContentResolver();
String selection = ContactsContract.Data.MIMETYPE + " = ? AND " + ContactsContract.Data.RAW_CONTACT_ID + " = ? ";
String[] selectionArgs = new String[] { "vnd.android.cursor.item/vnd.com.whatsapp.voip.call", rawContactId };
Cursor cursor = resolver.query(
ContactsContract.Data.CONTENT_URI,
null, selection, selectionArgs,
ContactsContract.Contacts.DISPLAY_NAME);
long _id=0;
while (cursor.moveToNext()) {
_id = cursor.getLong(cursor.getColumnIndex(ContactsContract.Data._ID));
String displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
String mimeType = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.MIMETYPE));
Log.d(TAG, "Data: " + _id+ " "+ displayName + " " + mimeType );
}
return _id;
}
@Adnan Khan 提供的答案适用于 Android 11,但我想提供他的答案的 Kotlin 版本:
val resolver: ContentResolver = requireContext().contentResolver
val cursor: Cursor? = resolver.query(
ContactsContract.Data.CONTENT_URI,
null, null, null,
ContactsContract.Contacts.DISPLAY_NAME)
while(cursor!!.moveToNext()) {
val _id: Long = cursor.getLong(cursor.getColumnIndex(ContactsContract.Data._ID))
val displayName: String = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.DISPLAY_NAME))
val mimeType: String = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.MIMETYPE))
Log.i("Intents", "$_id $displayName $mimeType")
现在,Kotlin 中的意图是这样的: _id是你之前路由得到的值
val intent = Intent()
intent.action = Intent.ACTION_VIEW
intent.setDataAndType(Uri.parse("content://com.android.contacts/data/_id"),
"vnd.android.cursor.item/vnd.com.whatsapp.voip.call")
intent.setPackage("com.whatsapp")
startActivity(intent)
最后但并非最不重要的是将以下内容添加到 AndroidManifest.xml 中:
<uses-permission
android:name="android.permission.CALL_PHONE"
androd:maxSdkVersion="30" />
<uses-permission
android:name="android.permission.READ_CONTACTS"
androd:maxSdkVersion="30" />
此后,您需要进入设置 -> 应用程序 -> 选择您的应用程序并将这两个权限标记为允许。
应用程序应该有一种方式在第一次运行时询问您,但这是另一个主题。

对于那些迟到的人:希望这个答案能够通过提供从电话号码到
Intent
发起视频通话的简化流程来改进其他答案。
请注意,只有在设备上注册了联系人并且安装了 WhatsApp 时,此功能才有效。在清单中,您将需要权限
READ_CONTACTS
和 CALL_PHONE
,以及定义 <queries>
包的 com.whatsapp
标签。
private void call(String phoneNumber) {
Long contactId = this.findContactId(phoneNumber);
if(contactId == null){
this.message("No contact registered with this phone number.");
return;
}
Long dataId = this.findWAVideoCallDataId(contactId);
if(dataId == null){
this.message("Contact has no whatsapp video call link.");
return;
}
this.openVideoCallAppLink(dataId);
}
这将查询
Contacts
表并返回与电话号码关联的 ContactId
。
private Long findContactId(String phoneNumber) {
ContentResolver resolver = getApplicationContext().getContentResolver();
Uri filterUri = Uri.withAppendedPath(ContactsContract.CommonDataKinds.Phone.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
String[] projection = new String[]{ContactsContract.CommonDataKinds.Phone.CONTACT_ID};
Cursor cursor = resolver.query(filterUri, projection, null, null, null);
try {
if (cursor.moveToNext()) {
return cursor.getLong(cursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
}
} finally {
cursor.close();
}
return null;
}
这将查询
Data
表并查找与具有 mimeType ContactId
的
vnd.android.cursor.item/vnd.com.whatsapp.video.call
关联的子记录
private Long findWAVideoCallDataId(Long contactId) {
String[] projection = new String[]{ContactsContract.Data._ID};
String selection = ContactsContract.Data.CONTACT_ID + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?";
String[] selectionArgs = new String[]{contactId.toString(), "vnd.android.cursor.item/vnd.com.whatsapp.video.call"};
Cursor cursor = getApplicationContext().getContentResolver().query(
ContactsContract.Data.CONTENT_URI,
projection,
selection,
selectionArgs,
null
);
if (cursor != null) {
try {
if (cursor.moveToNext()) {
return cursor.getLong(cursor.getColumnIndexOrThrow(ContactsContract.Data._ID));
}
} finally {
cursor.close();
}
}
return null;
}
最后,这个
DataId
用来组成Intent
的URI。
private void openVideoCallAppLink(Long dataId) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse("content://com.android.contacts/data/" + dataId),
"vnd.android.cursor.item/vnd.com.whatsapp.video.call");
intent.setPackage("com.whatsapp");
if (intent.resolveActivity(getPackageManager()) != null) {
startActivity(intent);
} else {
message("No app resolved to open whatsapp link.");
}
}
