Com*_*Guy 55 android contact android-intent whatsapp
我想知道如何将文本发送到特定的WhatsApp联系人.我找到了一些代码来查看特定联系人,但不发送数据.
Cursor c = getContentResolver().query(ContactsContract.Data.CONTENT_URI,
new String[] { ContactsContract.Contacts.Data._ID }, ContactsContract.Data.DATA1 + "=?",
new String[] { id }, null);
c.moveToFirst();
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("content://com.android.contacts/data/" + c.getString(0)));
startActivity(i);
c.close();
这适用于查看whatsapp-contact,但我现在如何添加一些文本？或者Whatsapp开发人员没有实现这样的api？

我认为答案是你的问题和这个答案的混合:https://stackoverflow.com/a/15931345/734687 所以我会尝试以下代码:
Intent i = new Intent(Intent.ACTION_SENDTO, Uri.parse("content://com.android.contacts/data/" + c.getString(0)));
i.setType("text/plain");
i.setPackage("com.whatsapp"); // so that only Whatsapp reacts and not the chooser
i.putExtra(Intent.EXTRA_SUBJECT, "Subject");
i.putExtra(Intent.EXTRA_TEXT, "I'm the body.");
startActivity(i);
我查看了Whatsapp清单,发现ACTION_SEND已注册到活动中ContactPicker,因此无法帮助您.但是ACTION_SENDTO已注册到活动中com.whatsapp.Conversation,这听起来更适合您的问题.
Whatsapp可以作为发送短信的替代品,所以它应该像短信一样工作.如果未指定所需的应用程序(通过setPackage),Android将显示应用程序选择器.因此,您应该查看通过意图发送SMS的代码,然后提供其他包信息.
Uri uri = Uri.parse("smsto:" + smsNumber);
Intent i = new Intent(Intent.ACTION_SENDTO, uri);
i.putExtra("sms_body", smsText);
i.setPackage("com.whatsapp");
startActivity(i);
首先尝试将意图替换ACTION_SEND为ACTION_SENDTO.如果这不起作用,则提供额外的额外费用sms_body.如果这不起作用,请尝试更改uri.
更新 我试图自己解决这个问题,但无法找到解决方案.Whatsapp打开聊天记录,但不接收文本并发送.似乎这个功能没有实现.

我找到了正确的方法,这很简单,你只需要阅读这篇文章:http://howdygeeks.com/send-whatsapp-message-unsaved-number-android/
源代码:phone并且message都是String.
PackageManager packageManager = context.getPackageManager();
Intent i = new Intent(Intent.ACTION_VIEW);
try {
String url = "https://api.whatsapp.com/send?phone="+ phone +"&text=" + URLEncoder.encode(message, "UTF-8");
i.setPackage("com.whatsapp");
i.setData(Uri.parse(url));
if (i.resolveActivity(packageManager) != null) {
context.startActivity(i);
}
} catch (Exception e){
e.printStackTrace();
}
请享用!

我已经做了!
private void openWhatsApp() {
String smsNumber = "7****"; // E164 format without '+' sign
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("text/plain");
sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
sendIntent.putExtra("jid", smsNumber + "@s.whatsapp.net"); //phone number without "+" prefix
sendIntent.setPackage("com.whatsapp");
if (intent.resolveActivity(getActivity().getPackageManager()) == null) {
Toast.makeText(this, "Error/n" + e.toString(), Toast.LENGTH_SHORT).show();
return;
}
startActivity(sendIntent);
}

这种方法也适用于WhatsApp Business应用程序!
将包名更改为sendIntent.setPackage("com.whatsapp.w4b"); 为WhatsApp业务.
非常好的黑客Rishabh,非常感谢,自从过去3年以来我一直在寻找这个解决方案.
根据Rishabh Maurya上面的回答,我已经实现了这个代码,它在WhatsApp上的文本和图像共享都很好.
请注意,在这两种情况下,它都会打开一个whatsapp会话(如果toNumber存在于用户whatsapp联系人列表中),但用户必须单击"发送"按钮才能完成操作.这意味着它有助于跳过联系人选择步骤.
用于短信
String toNumber = "+91 98765 43210"; // contains spaces.
toNumber = toNumber.replace("+", "").replace(" ", "");
Intent sendIntent = new Intent("android.intent.action.MAIN");
sendIntent.putExtra("jid", toNumber + "@s.whatsapp.net");
sendIntent.putExtra(Intent.EXTRA_TEXT, message);
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.setPackage("com.whatsapp");
sendIntent.setType("text/plain");
startActivity(sendIntent);
用于共享图像
String toNumber = "+91 98765 43210"; // contains spaces.
toNumber = toNumber.replace("+", "").replace(" ", "");
Intent sendIntent = new Intent("android.intent.action.MAIN");
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(imageFile));
sendIntent.putExtra("jid", toNumber + "@s.whatsapp.net");
sendIntent.putExtra(Intent.EXTRA_TEXT, message);
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.setPackage("com.whatsapp");
sendIntent.setType("image/png");
context.startActivity(sendIntent);
享受WhatsApping!

它允许您为您尝试与之通信的特定用户打开WhatsApp对话屏幕:
private void openWhatsApp() {
String smsNumber = "91XXXXXXXX20";
boolean isWhatsappInstalled = whatsappInstalledOrNot("com.whatsapp");
if (isWhatsappInstalled) {
Intent sendIntent = new Intent("android.intent.action.MAIN");
sendIntent.setComponent(new ComponentName("com.whatsapp", "com.whatsapp.Conversation"));
sendIntent.putExtra("jid", PhoneNumberUtils.stripSeparators(smsNumber) + "@s.whatsapp.net");//phone number without "+" prefix
startActivity(sendIntent);
} else {
Uri uri = Uri.parse("market://details?id=com.whatsapp");
Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri);
Toast.makeText(this, "WhatsApp not Installed",
Toast.LENGTH_SHORT).show();
startActivity(goToMarket);
}
}
private boolean whatsappInstalledOrNot(String uri) {
PackageManager pm = getPackageManager();
boolean app_installed = false;
try {
pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
app_installed = true;
} catch (PackageManager.NameNotFoundException e) {
app_installed = false;
}
return app_installed;
}

看看我的答案:https://stackoverflow.com/a/40285262/5879376
Intent sendIntent = new Intent("android.intent.action.MAIN");
sendIntent.setComponent(new ComponentName("com.whatsapp","com.whatsapp.Conversation"));
sendIntent.putExtra("jid", PhoneNumberUtils.stripSeparators("YOUR_PHONE_NUMBER")+"@s.whatsapp.net");//phone number without "+" prefix
startActivity(sendIntent);

这将首先搜索指定的联系人,然后打开聊天窗口.如果没有安装WhatsApp,那么try-catch块处理这个.
String digits = "\\d+";
Sring mob_num = 987654321;
if (mob_num.matches(digits))
{
try {
/linking for whatsapp
Uri uri = Uri.parse("whatsapp://send?phone=+91" + mob_num);
Intent i = new Intent(Intent.ACTION_VIEW, uri);
startActivity(i);
}
catch (ActivityNotFoundException e){
e.printStackTrace();
Toast.makeText(this, "WhatsApp not installed.", Toast.LENGTH_SHORT).show();
}
}
我正在尝试使用另一个应用程序在 WhatsApp 中发送短信。
假设我们有一个按钮，在按钮上单击您调用下面的方法。
sendTextMsgOnWhatsApp("+91 9876543210", "你好，这是我的测试消息");
public void sendTextMsgOnWhatsApp(String sContactNo, String sMessage) {
String toNumber = sContactNo; // contains spaces, i.e., example +91 98765 43210
toNumber = toNumber.replace("+", "").replace(" ", "");
/*this method contactIdByPhoneNumber() will get unique id for given contact,
if this return's null then it means that you don't have any contact save with this mobile no.*/
String sContactId = contactIdByPhoneNumber(toNumber);
if (sContactId != null && sContactId.length() > 0) {
/*
* Once We get the contact id, we check whether contact has a registered with WhatsApp or not.
* this hasWhatsApp(hasWhatsApp) method will return null,
* if contact doesn't associate with whatsApp services.
* */
String sWhatsAppNo = hasWhatsApp(sContactId);
if (sWhatsAppNo != null && sWhatsAppNo.length() > 0) {
Intent sendIntent = new Intent("android.intent.action.MAIN");
sendIntent.putExtra("jid", toNumber + "@s.whatsapp.net");
sendIntent.putExtra(Intent.EXTRA_TEXT, sMessage);
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.setPackage("com.whatsapp");
sendIntent.setType("text/plain");
startActivity(sendIntent);
} else {
// this contact does not exist in any WhatsApp application
Toast.makeText(this, "Contact not found in WhatsApp !!", Toast.LENGTH_SHORT).show();
}
} else {
// this contact does not exist in your contact
Toast.makeText(this, "create contact for " + toNumber, Toast.LENGTH_SHORT).show();
}
}
private String contactIdByPhoneNumber(String phoneNumber) {
String contactId = null;
if (phoneNumber != null && phoneNumber.length() > 0) {
ContentResolver contentResolver = getContentResolver();
Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
String[] projection = new String[]{ContactsContract.PhoneLookup._ID};
Cursor cursor = contentResolver.query(uri, projection, null, null, null);
if (cursor != null) {
while (cursor.moveToNext()) {
contactId = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.PhoneLookup._ID));
}
cursor.close();
}
}
return contactId;
}
public String hasWhatsApp(String contactID) {
String rowContactId = null;
boolean hasWhatsApp;
String[] projection = new String[]{ContactsContract.RawContacts._ID};
String selection = ContactsContract.RawContacts.CONTACT_ID + " = ? AND " + ContactsContract.RawContacts.ACCOUNT_TYPE + " = ?";
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;
}
在AndroidManifest.xml文件中添加以下权限
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
<uses-permission android:name="android.permission.INTERNET" />
Whatsapp have its own API
Intent sendIntent = new Intent("android.intent.action.MAIN");
sendIntent.setAction(Intent.ACTION_VIEW);
sendIntent.setPackage("com.whatsapp");
String url = "https://api.whatsapp.com/send?phone=" + "Phone with international format" + "&text=" + "your message";
sendIntent.setData(Uri.parse(url));
if(sendIntent.resolveActivity(context.getPackageManager()) != null){
startActivity(sendIntent);
}
Code updated check added for Activity is available or not.
现在可以通过WhatsApp Business API实现这一点。只有企业可以申请使用。这是直接向电话号码发送消息而无需任何人工交互的唯一方法。
发送普通消息是免费的。看起来您需要在服务器上托管 MySQL 数据库和 WhatsApp Business 客户端。
