android--Simple Texting function

First, prepare the character resource

<string name= "Tip_phone" > Please enter your phone number </string>

<string name= "Tip_sms" > Please enter send Message </string>

<string name= "Tip_send" > Send </string>

Second, the page 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"

tools:context= "${relativepackage}.${activityclass}" >

<textview

Android:id= "@+id/tvphone"

Android:layout_width= "Match_parent"

android:layout_height= "Wrap_content"

android:text= "@string/tip_phone"/>

<edittext

Android:id= "@+id/etphone"

Android:layout_width= "Match_parent"

android:layout_height= "Wrap_content"

android:layout_below= "@+id/tvphone"

Android:inputtype= "Phone"/>

<textview

Android:id= "@+id/tvsms"

Android:layout_width= "Match_parent"

android:layout_height= "Wrap_content"

android:layout_below= "@+id/etphone"

android:text= "@string/tip_sms"/>

<edittext

Android:id= "@+id/etsms"

Android:layout_width= "Match_parent"

android:layout_height= "100DP"

android:layout_below= "@+id/tvsms"

Android:inputtype= "textmultiline"/><!-SMS content line-up

<button

Android:id= "@+id/sendbtn"

Android:layout_width= "Wrap_content"

android:layout_height= "Wrap_content"

android:layout_below= "@+id/etsms"

android:onclick= "Sendsms"

android:text= "@string/tip_send"/>

</RelativeLayout>

Third, the specific implementation of the Code

public class Smsactivity extends Activity {

Private EditText etphone,etsms;

@Override

protected void OnCreate (Bundle savedinstancestate) {

Super.oncreate (savedinstancestate);

Setcontentview (r.layout.activity_sms);

Gets the phone number of the control object

Etphone= (EditText) Findviewbyid (R.id.etphone);

Gets the control object that sent the message

Etsms= (EditText) Findviewbyid (r.id.etsms);

}

public void Sendsms (View v) {

Switch (V.getid ()) {

Case R.ID.SENDBTN:

String Phone=etphone.gettext (). toString ();

String Content=etsms.gettext (). toString ();

2. Message Manager Object

Smsmanager Smsmanager=smsmanager.getdefault ();

3. Split SMS Content

List<string> list=smsmanager.dividemessage (content);

4. Traverse the Sending message

for (String sms:list) {

5. Send a message

Smsmanager.sendtextmessage (phone, NULL, SMS, NULL, NULL);

}

6. Prompt text message sent successfully

Toast.maketext (This, "sent successfully", Toast.length_long). Show ();

Break

Default

Break

}

}

}

Iv. Obtaining permissions

Add text message permissions in Androidmanifest.xml

<uses-permissionandroid:name= "Android.permission.SEND_SMS"/>

The final effect is as follows:
