群发短信(不是直接发送，只是调起系统短信发送页面，联系人自动填入)
这里面注意的就是symbol分隔符，目前测试都已经适配(也反编译过CM的WhatsCall产品)
public static void sendSms(Context context, String text, List<String> numbers) {
String numbersStr = "";
String symbol = "Samsung".equalsIgnoreCase(Build.MANUFACTURER) ? ",": ";";
if (numbers != null && !numbers.isEmpty()) {
numbersStr = TextUtils.join(symbol, numbers);
}
Uri uri = Uri.parse("smsto:" + numbersStr);
Intent intent = new Intent();
intent.setData(uri);
intent.putExtra("sms_body", text);
intent.setAction(Intent.ACTION_SENDTO);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
String defaultSmsPackageName = Telephony.Sms.getDefaultSmsPackage(context);
if (defaultSmsPackageName != null) {
intent.setPackage(defaultSmsPackageName);
}
}
if (!(context instanceof Activity)) {
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
}
try {
context.startActivity(intent);
} catch (Exception e) {
}
}
上面代码是不需要任何权限的！
如果要做短信群发可以使用:
smsManager.sendTextMessage(etNumber.getText().toString(), null,etMessage.getText().toString(), null, null);
后面2个参数是监听短信发送成功失败等状态
发送短信记得添加权限：
<uses-permission android:name="android.permission.SEND_SMS"/>
读取手机联系人信息：
<uses-permission android:name="android.permission.READ_CONTACTS"/>
public static List<PhoneContact> getAllContactList(Context context) {
List<PhoneContact> smsContactList = new ArrayList<>();
try {
Cursor cursor = context.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
new String[]{ContactsContract.CommonDataKinds.Phone.CONTACT_ID, ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME}
, null, null, ContactsContract.CommonDataKinds.Phone.SORT_KEY_PRIMARY);
if (cursor != null && cursor.getCount() > 0) {
String lastPhone = null;
while (cursor.moveToNext()) {
PhoneContact smsContact = new PhoneContact();
smsContact.name = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
smsContact.contactId = cursor.getLong(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
String phone = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
if (!TextUtils.isEmpty(phone)) {
//安卓本身的电话获取出来是经过格式化的， 不是连续的数字
phone = formatNum(phone);
smsContact.number = phone;
if (TextUtils.isEmpty(phone) || TextUtils.equals(lastPhone, phone)) {
continue;
}
lastPhone = phone;
}
smsContactList.add(smsContact);
}
}
if (cursor != null) {
try {
cursor.close();
} catch (Throwable throwable) {
}
}
} catch (Exception e) {
}
return smsContactList;
}
private static String formatNum(String phone) {
if (phone != null) {
char x20 = 0x20;
char xa0 = 0xa0;
phone = phone.replace(x20, xa0);
phone = phone.replace(" ", "");
phone = phone.replace(" ", "");
phone = phone.replace("-", "");
}
return phone;
}
关于检查某些权限是否授权：
（这是编译的targetSDK导致，可以如下代码处理！但是发现有些华为，小米手机，去设置页面关闭权限，下面代码还是不好使，知道具体怎么解决的，可以留言告知谢谢！）
int targetSdkVersion = 0;
try {
final PackageInfo info = context.getPackageManager().getPackageInfo(
context.getPackageName(), 0);
targetSdkVersion = info.applicationInfo.targetSdkVersion;
} catch (Exception e) {
}
boolean isGrant = false;
if (targetSdkVersion >= Build.VERSION_CODES.M){
isGrant = ContextCompat.checkSelfPermission(context, Manifest.permission.READ_CONTACTS) == PackageManager.PERMISSION_GRANTED;
}else{
isGrant = PermissionChecker.checkSelfPermission(context, Manifest.permission.READ_CONTACTS) == PermissionChecker.PERMISSION_GRANTED;
}
