我想用 Android 发送短信。
发送短信的目的是什么？
我想显示撰写短信视图，并在消息字段中传递我的预定义文本。
【问题讨论】：
您可以省略电话号码，让用户只从联系人中进行选择，但在正文中插入您的短信文本。代码适用于 Xamarin Android：
var uri = Uri.Parse("smsto:"); //append your number here for explicit nb
var intent = new Intent(Intent.ActionSendto, uri);
intent.PutExtra("sms_body", text);
Context.StartActivity(intent);
在哪里
上下文是Xamarin.Essentials.Platform.CurrentActivity ?? Application.Context
【讨论】：
您可以使用它向任何号码发送短信：
public void sendsms(View view) {
String phoneNumber = "+880xxxxxxxxxx";
String message = "Welcome to sms";
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("sms:" + phoneNumber));
intent.putExtra("sms_body", message);
startActivity(intent);
}
【讨论】：
上面解释的某些内容仅用于将 SMS 置于“准备启动”状态。
正如 Senthil Mg 所说，您可以使用短信管理器直接发送短信，但 SMSManager 已移至 android.telephony.SmsManager
我知道这不是很多更多信息，但有一天它可能会对某人有所帮助。
【讨论】：
从 KitKat 及以上发送短信：- 在您的 AndroidManifest.xml
中添加此权限<uses-permission android:name="android.permission.SEND_SMS"/>
您还应该实现 Marshmallow 及以上版本的运行时权限。
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.defaultmessanginggit">
<uses-permission android:name="android.permission.SEND_SMS"/>
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity
android:name=".ConversationListActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".ComposeSMSActivity"
android:label="@string/title_activity_compose_sms" >
</activity>
</application>
</manifest>
代码如下：-
activity_conversation_list.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent"

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Message" />
</LinearLayout>
ConversationListActivity.java
public class ConversationListActivity extends FragmentActivity {
/**
* Whether or not the activity is in two-pane mode, i.e. running on a tablet
* device.
*/
private int PERMISSIONS_REQUEST_RECEIVE_SMS = 130;
private Button btn_send_sms;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_conversation_list);
btn_send_sms = (Button) findViewById(R.id.btn_send_msg);
btn_send_sms.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
int hasSendSMSPermission = 0;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
hasSendSMSPermission = checkSelfPermission(Manifest.permission.SEND_SMS);
if (hasSendSMSPermission != PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[]{Manifest.permission.SEND_SMS},
PERMISSIONS_REQUEST_RECEIVE_SMS);
} else if (hasSendSMSPermission == PackageManager.PERMISSION_GRANTED) {
Intent intent = new Intent(ConversationListActivity.this, ComposeSMSActivity.class);
startActivity(intent);
}
}else{
Intent intent = new Intent(ConversationListActivity.this, ComposeSMSActivity.class);

就是这样。
【讨论】：
试试下面的代码，然后拨打sendSMS("99999999999", "message");以发送所需号码的短信。
//---sends an SMS message to another device---
@SuppressWarnings("deprecation")
private void sendSMS(String phoneNumber, String message)
{
Log.v("phoneNumber",phoneNumber);
Log.v("MEssage",message);
PendingIntent pi = PendingIntent.getActivity(this, 0,
new Intent(this, **DummyClasshere.class**), 0);
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, null, message, pi, null);
}
请将以下权限放入AndroidManifest.xml 文件中。
<uses-permission android:name="android.permission.SEND_SMS"/>
希望这可能会有所帮助。
更新 来自评论： DummyClasshere.class 是一项活动，无需执行任何流程或您需要在其中导航的类。
您可以使用 Object.class 代替 DummyClasshere.class。
【讨论】：
new Intent() 就可以了。
这允许通过现有应用程序发送短信。 phoneNumber - 是字符串。如果您不想指定电话号码，请使用空字符串“”。
Intent sendIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("smsto", phoneNumber, null));
sendIntent.putExtra("sms_body", "text message");
startActivity(sendIntent);
【讨论】：
您可以使用以下代码：
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("sms:"
+ phoneNumber)));
确保将phoneNumber设置为您要向其发送消息的电话号码
您可以使用（来自 cmets）向 SMS 添加消息：
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("sms:" + phoneNumber));
intent.putExtra("sms_body", message);
startActivity(intent);

如果它可以帮助某人，我会添加我的 SMS 方法。 小心 smsManager.sendTextMessage，如果文本太长，消息不会消失。您必须尊重最大长度，具体取决于编码。 更多信息在这里SMS Manager send mutlipart message when there is less than 160 characters

SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneNumber, null, message, null, null);
在您的 AndroidManifest.xml 文件中包含以下权限
<uses-permission android:name="android.permission.SEND_SMS" />
【讨论】：
这肯定会起作用，在此，不使用任何意图发送消息。
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage("Phone Number", null, "Message", null, null);
此代码用于在后台发送消息（不显示消息编写器），它也可以在广播接收器内部工作。如果你想从广播接收器发送消息。
<uses-permission android:name="android.permission.SEND_SMS"/>
【讨论】：
在 Android 中，我们有类 SmsManager 来管理 SMS 操作，例如发送数据、文本和 pdu SMS 消息。通过调用静态方法 SmsManager.getDefault() 获取该对象。
