Calling and sending text messages can be said to be the core application. This article will describe its calling method. It can be divided into direct call-direct call or text message sending, or indirect call-to enter the dialing or text message Writing Page, waiting for the user to confirm the content before the user sends out.

First look at the code effect:

First, write activaty on the main interface and create the callandsms class as the default startup page.Package jtapp. callandsms; </p> <p> import java. util. list; </p> <p> import android. app. activity; <br/> import android. content. intent; <br/> import android.net. uri; <br/> import android. OS. bundle; <br/> import android. telephony. smsManager; <br/> import android. view. view; <br/> import android. view. view. onClickListener; <br/> import android. widget. button; <br/> import android. widget. toast; </p> <p> public class CallAndSms extends Activity {<br/>/** Called when the activity is first created. */<br/> @ Override <br/> public void onCreate (Bundle savedInstanceState) {<br/> super. onCreate (savedInstanceState); <br/> setContentView (R. layout. main); </p> <p> setComponent (); <br/>}</p> <p> private void setComponent () {<br/> Button bt1 = (Button) findViewById (R. id. button01); <br/> bt1.setOnClickListener (new OnClickListener () {<br/> @ Override <br/> public void onClick (View v) {<br/> Intent intent = new Intent (<br/> Intent. ACTION_CALL, Uri. parse ("tel: 10010"); <br/> startActivity (intent); <br/>}< br/> }); <br/> Button bt2 = (Button) findViewById (R. id. button02); <br/> bt2.setOnClickListener (new OnClickListener () {<br/> @ Override <br/> public void onClick (View v) {<br/> String smsContent = "102"; <br/> // note: SMS must be divided before being sent <br/> SmsManager sms = SmsManager. getDefault (); <br/> List <String> texts = sms. divideMessage (smsContent); <br/> for (String text: texts) {<br/> sms. sendTextMessage ("10010", null, text, null, null); <br/>}< br/> // note: not checked success or failure yet <br/> Toast. makeText (<br/> CallAndSms. this, <br/> "sms sent", <br/> Toast. LENGTH_SHORT ). show (); <br/>}< br/>}); </p> <p> Button bt3 = (Button) findViewById (R. id. button03); <br/> bt3.setOnClickListener (new OnClickListener () {<br/> @ Override <br/> public void onClick (View v) {<br/> Intent intent = new Intent (<br/> Intent. ACTION_DIAL, Uri. parse ("tel: 10010"); <br/> startActivity (intent); <br/>}< br/> }); <br/> Button bt4 = (Button) findViewById (R. id. button04); <br/> bt4.setOnClickListener (new OnClickListener () {<br/> @ Override <br/> public void onClick (View v) {<br/> Uri uri = Uri. parse ("smsto: 10010"); <br/> Intent it = new Intent (Intent. ACTION_SENDTO, uri); <br/> it. putExtra ("sms_body", "102"); <br/> startActivity (it); <br/>}< br/> }); <br/>}< br/>}

The main UI defines the main. XML code:

<? Xml version = "1.0" encoding = "UTF-8"?> <Br/> <LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android" <br/> android: orientation = "vertical" android: layout_width = "fill_parent" <br/> android: layout_height = "fill_parent" android: gravity = "center"> <br/> <TextView android: layout_width = "fill_parent" <br/> android: layout_height = "wrap_content" android: text = "Direct Method:" <br/> android: gravity = "center"/> <br/> <Button android: text = "Call 10010 Customer Service" android: id = "@ + id/Button01" <br/> android: layout_width = "wrap_content" android: layout_height = "wrap_content"> </Button> <br/> <Button android: text = "text message 10010 balance check" android: id = "@ + id/Button02" <br/> android: layout_width = "wrap_content" android: layout_height = "wrap_content"> </Button> <br/> <TextView android: text = "InDirect Method:" android: id = "@ + id/TextView01" <br/> android: layout_width = "wrap_content" android: layout_height = "wrap_content"/> <br/> <Button android: text = "Call 10010 Customer Service" android: id = "@ + id/Button03" <br/> android: layout_width = "wrap_content" android: layout_height = "wrap_content"> </Button> <br/> <Button android: text = "SMS 10010 balance check" android: id = "@ + id/Button04" <br/> android: layout_width = "wrap_content" android: layout_height = "wrap_content"> </Button> <br/> </LinearLayout>

The file used to listen to the broadcast message sent by the SMS,

Receiversms. Java code:

Package jtapp. callandsms; </P> <p> Import android. content. broadcastreceiver; <br/> Import android. content. context; <br/> Import android. content. intent; <br/> Import android. OS. bundle; <br/> Import android. telephony. smsmessage; <br/> Import android. widget. toast; </P> <p> public class receiversms extends broadcastreceiver {</P> <p> @ override <br/> Public void onreceive (context, intent) {<br/> If (in Tent. getaction (). equals (<br/> "android. provider. telephony. sms_received ") {<br/> stringbuilder sb = new stringbuilder (); <br/> bundle = intent. getextras (); <br/> If (bundle! = NULL) {<br/> object [] PDUS = (object []) bundle. get ("PDUS"); <br/> smsmessage [] msgs = new smsmessage [PDUS. length]; <br/> for (INT I = 0; I <PDUS. length; I ++) {<br/> msgs [I] = smsmessage <br/>. createfrompdu (byte []) PDUS [I]); <br/>}< br/> for (smsmessage S: MSGs) {<br/> Sb. append ("received from"); <br/> Sb. append (S. getdisplayoriginatingaddress (); <br/> Sb. append ("SMS, content:"); <br/> Sb. append (S. getdisplaymessagebody (); <br/>}< br/> toast. maketext (<br/> context, <br/> "received short message:" + sb. tostring (), <br/> toast. length_long ). show (); <br/>}</P> <p >}< br/>

In androidmanifest. XML, the permission, activity, and handler settings are as follows:

<? XML version = "1.0" encoding = "UTF-8"?> <Br/> <manifest xmlns: Android = "http://schemas.android.com/apk/res/android" <br/> package = "jtapp. callandsms "Android: versioncode =" 1 "Android: versionname =" 1.0 "> <br/> <application Android: icon =" @ drawable/icon "Android: label = "@ string/app_name" <br/> Android: debuggable = "true"> <br/> <activity Android: Name = ". callandsms "Android: Label =" @ string/app_name "> <br/> <intent-filter> <br/> <action Android: Name =" android. intent. action. main "/> <br/> <category Android: Name =" android. intent. category. launcher "/> <br/> </intent-filter> <br/> </activity> <br/> <Cycler Android: Name = ". receiversms "Android: enabled =" true "> <br/> <intent-filter> <br/> <action Android: Name =" android. provider. telephony. sms_received "/> <br/> </intent-filter> <br/> </javaser> <br/> </Application> <br/> <uses-Permission Android: name = "android. permission. call_phone "> </uses-Permission> <br/> <uses-Permission Android: Name =" android. permission. send_sms "> </uses-Permission> <br/> <uses-Permission Android: Name =" android. permission. receive_sms "> </uses-Permission> <br/> </manifest>

 

 

Add, send email code snippets:

// Email <br/> Button bt5 = (Button) findViewById (R. id. button05); <br/> bt5.setOnClickListener (new OnClickListener () {<br/> @ Override <br/> public void onClick (View v) {<br/> // Setup the recipient in a String array <br/> String [] mailto = {"noam@gmail.com "}; <br/> // Create a new Intent to send messages <br/> Intent sendIntent = new Intent (Intent. ACTION_SEND); <br/> // Write the body of theEmail <br/> String emailBody = "You're password is :"; <br/> // Add attributes to the intent <br/> // sendIntent. setType ("text/plain"); // use this line for testing <br/> // in the emulator <br/> sendIntent. setType ("message/rfc822"); // use this line for testing <br/> // on the real phone <br/> sendIntent. putExtra (Intent. EXTRA_EMAIL, mailto); <br/> sendIntent. putExtra (Intent. EXTRA_SUBJECT, "Your Password"); <br/> sendIntent. putExtra (Intent. EXTRA_TEXT, emailBody); <br/> startActivity (sendIntent); <br/>}< br/> });
