当用户按下屏幕上的按钮时,我会尝试自动将短信发送到某个号码。
这是我的代码:
Intent smsIntent = new Intent(Intent.ACTION_SENDTO,
Uri.parse("sms:xxxxxxxxxxx"));
smsIntent.putExtra("sms_body", "Hello");
startActivity(smsIntent);
xxxxxxx =电话号码
我拥有以下权限:
<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>
<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
当我按下按钮时,它会转到另一个屏幕,在那里我可以编辑我的文本并按发送。我只是想让它自动完成这个过程,而不会把我带到另一个屏幕。由于我已经定义了我的消息,我只想将其发送给特定的号码。
而且我也不确定我是否将更正的电话号码放在第二行代码中。我是否必须首先将我的国家/地区代码放在那里,或者我可以只放我的手机号码,它会起作用吗?
谢谢

试试这段代码:
String messageToSend = "this is a message";
String number = "2121234567";
SmsManager.getDefault().sendTextMessage(number, null, messageToSend, null,null);
关于号码,您需要输入号码,就像您通过电话拨打电话或以正常方式发送短信一样。

您也可以在Intent中使用构建:
buttonSendSms_intent.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
String smsNumber = edittextSmsNumber.getText().toString();
String smsText = edittextSmsText.getText().toString();
Uri uri = Uri.parse("smsto:" + smsNumber);
Intent intent = new Intent(Intent.ACTION_SENDTO, uri);
intent.putExtra("sms_body", smsText);
startActivity(intent);
}});

试试这个
private static final String SMS_SENT_INTENT_FILTER = "com.yourapp.sms_send";
private static final String SMS_DELIVERED_INTENT_FILTER = "com.yourapp.sms_delivered";
String message = "hey, this is my message";
String phnNo = " " //preferable use complete international number
PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, new Intent(
SMS_SENT_INTENT_FILTER), 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0, new Intent(
SMS_DELIVERED_INTENT_FILTER), 0);
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phnNo, null, message, sentPI, deliveredPI);

简单的方法是使用SmsManager.Telephony。
答案 4 :(得分:0)
首先设置以下权限:
<uses-permission android:name="android.permission.SEND_SMS"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
然后创建以下活动:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<EditText
android:id="@+id/editText"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginEnd="41dp"
android:layout_marginLeft="41dp"
android:layout_marginRight="41dp"
android:layout_marginStart="41dp"
android:layout_marginTop="43dp"
android:ems="10"
android:hint="Enter Phone no"
android:inputType="textPersonName"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<EditText
android:id="@+id/editText2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginEnd="37dp"
android:layout_marginLeft="37dp"
android:layout_marginRight="37dp"
android:layout_marginStart="37dp"
android:layout_marginTop="28dp"
android:ems="10"
android:hint="Enter text"
android:inputType="textPersonName"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/editText" />
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="183dp"
android:text="SEND"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent" />
</android.support.constraint.ConstraintLayout>
现在转到您的 MainActivity.java 文件并添加以下代码:
public class MainActivity extends AppCompatActivity {
EditText e1, e2;
Button b1;
private final static int SEND_SMS_PERMISSION_REQ=1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
e1=findViewById(R.id.editText);
e2=findViewById(R.id.editText2);
b1=findViewById(R.id.button);
b1.setEnabled(false);
if(checkPermission(Manifest.permission.SEND_SMS))
{
b1.setEnabled(true);
}
else
{
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.SEND_SMS}, SEND_SMS_PERMISSION_REQ);
}
b1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String s1=e1.getText().toString();
String s2=e2.getText().toString();
if(!TextUtils.isEmpty(s1)&&!TextUtils.isEmpty(s2))
{
if(checkPermission(Manifest.permission.SEND_SMS))
{
SmsManager smsManager=SmsManager.getDefault();
smsManager.sendTextMessage(s1,null,s2,null,null);
}
else {
Toast.makeText(MainActivity.this, "Permission Denied", Toast.LENGTH_SHORT).show();
}
}
else
{
Toast.makeText(MainActivity.this, "Permission denied", Toast.LENGTH_SHORT).show();
}
}
});
}
private boolean checkPermission(String sendSms) {
int checkpermission= ContextCompat.checkSelfPermission(this,sendSms);
return checkpermission== PackageManager.PERMISSION_GRANTED;
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
switch (requestCode)
{
case SEND_SMS_PERMISSION_REQ:
if(grantResults.length>0 &&(grantResults[0]==PackageManager.PERMISSION_GRANTED))
{
b1.setEnabled(true);
}
break;
}
}
}
成功完成。
