Android SMS/MMS

First, activity_main.xml layout:

<RelativeLayout xmlns: android = "http://schemas.android.com/apk/res/android"
Xmlns: tools = "http://schemas.android.com/tools"
Android: layout_width = "match_parent"
Android: layout_height = "match_parent"
Android: paddingBottom = "@ dimen/activity_vertical_margin"
Android: paddingLeft = "@ dimen/activity_horizontal_margin"
Android: paddingRight = "@ dimen/activity_horizontal_margin"
Android: paddingTop = "@ dimen/activity_vertical_margin"
Tools: context = ". SmsActivity">

<TextView
Android: id = "@ + id/phone_lable"
Android: layout_width = "wrap_content"
Android: layout_height = "wrap_content"
Android: layout_alignParentTop = "true"
Android: layout_marginTop = "23dp"
Android: text = "@ string/phon_lable"/>

<EditText
Android: id = "@ + id/edit_phone"
Android: layout_width = "match_parent"
Android: layout_height = "wrap_content"
Android: layout_below = "@ + id/phone_lable"
Android: layout_centerHorizontal = "true"
Android: EMS = "10"

Android: inputType = "phone">

 

</EditText>

<TextView
Android: id = "@ + id/sms_lable"
Android: layout_width = "wrap_content"
Android: layout_height = "wrap_content"
Android: layout_alignLeft = "@ + id/edit_phone"
Android: layout_below = "@ + id/edit_phone"
Android: layout_marginTop = "22dp"
Android: text = "@ string/sms_lable"/>

<Button
Android: id = "@ + id/But_sms"
Android: layout_width = "wrap_content"
Android: layout_height = "wrap_content"
Android: layout_alignLeft = "@ + id/edit_sms"
Android: layout_alignParentBottom = "true"
Android: layout_marginBottom = "14dp"
Android: text = "@ string/But_sms"/>

<EditText
Android: id = "@ + id/edit_sms"
Android: layout_width = "match_parent"
Android: layout_height = "wrap_content"
Android: layout_above = "@ + id/But_sms"
Android: layout_alignLeft = "@ + id/sms_lable"
Android: EMS = "10"
Android: inputType = "textMultiLine"/>

 

</RelativeLayout>

Then, add the SMS sending permission to AndroidManifest. xml:
<Uses-permission android: name = "android. permission. SEND_SMS"/>

The following describes how to implement the main code in SmsActivity:

Public class SmsActivity extends Activity {

// Declare the control object
Private Button butten_sms;
Private EditText edit_phone;
Private EditText edit_sms;

@ Override
Protected void onCreate (Bundle savedInstanceState ){
Super. onCreate (savedInstanceState );
// Set the display view
SetContentView (R. layout. activity_sms );

// Obtain the button component
Butten_sms = (Button) findViewById (R. id. But_sms );

// Obtain the input box component
Edit_phone = (EditText) findViewById (R. id. edit_phone );

Edit_sms = (EditText) findViewById (R. id. edit_sms );

// Register button event
Butten_sms.setOnClickListener (new View. OnClickListener (){

@ Override
Public void onClick (View arg0 ){
/**
* Send MMS messages
*/
// Obtain the phone number
String phone_num = edit_phone.getText (). toString ();

// Create intent object
Intent intent = new Intent (Intent. ACTION_SEND );
Intent. putExtra (Intent. EXTRA_STREAM, Uri. parse ("file: // sdcard/a.jpg "));
Intent. putExtra ("address", phone_num );
Intent. putExtra ("exit_on_sent", true );
Intent. putExtra ("subject", "subject: I love you ");
Intent. putExtra ("sms_body", "content: XXXX ");
Intent. setType ("image/jpeg ");

StartActivity (intent );

/* // Obtain the text message manager object
SmsManager smsManager = SmsManager. getDefault ();
// Intent object
PendingIntent pendingIntent = PendingIntent. getBroadcast (
SmsActivity. this, 0, new Intent (), 0 );*/

}
});
}


// Text message function
Public void send (){
// Obtain the number
String phone_Num = edit_phone.getText (). toString ();

// Get the sent text message
String phone_sms = edit_sms.getText (). toString ();

// Obtain the information manager object
SmsManager smsmanager = SmsManager. getDefault ();

// Intent object
PendingIntent pendingIntent = PendingIntent. getBroadcast (SmsActivity. this, 0, new Intent (), 0 );

// If the message length is greater than 70, two messages are sent .. The default value is 70.
ArrayList <String> contents = smsmanager
. DivideMessage (phone_sms );
For (String c: contents ){
// Send information
Smsmanager. sendTextMessage (phone_Num, null, c,
PendingIntent, null );
}

/* // Send information
Smsmanager. sendTextMessage (phone_Num, null, phone_sms, pendingIntent, null );*/

// Effect of toast
Toast. makeText (SmsActivity. this, "sms sent successfully", Toast. LENGTH_LONG). show ();
}

@ Override
Public boolean onCreateOptionsMenu (Menu menu ){
// Inflate the menu; this adds items to the action bar if it is present.
GetMenuInflater (). inflate (R. menu. sms, menu );
Return true;
}

}
