Use the phone number stored in your phone to call and send a message to your contacts.

1. The data stored in the database layout to the phone interface, the operation please see http://blog.csdn.net/xia09222826/article/details/28660653

2. The three effects show the following effects:

1) Custom Effects

2) Single-radio effect

3) Multi-selection effect

3. Tap a contact to make a call or send a text message (for example, a custom effect)

1) Effect view (e.g. click on the number 1 contact): From the phone phone backup interface to jump to the Phoneandemailactitvity interface

2) Program implementation

① Register Click event Lv_users.setonitemclicklistener (this);

② uses Getitematposition () in the Onitemclick () method to obtain data based on location, using intent intent=new intent (mainactivity.this, Phoneandemailactivity.class); From the mobile phone backup interface to the Phoneandemailactitvity interface, use Putextra () method to get the information you want to pass to the Phoneandemailactitvity interface.

Note: You need to use startactivity (intent); Start activity

③ in Phoneandemailactitvity, the use of Intent intent=getintent (); String name = Intent.getstringextra ("username"); final string phone = Intent.getstringextra ("Userphone"); Get information that is passed from the phone backup interface

3) The realization of the function of dialing the telephone

① Create a Click event for a phone call button:

Tv_call.setonclicklistener (New View.onclicklistener () {@Overridepublic void OnClick (View v) {Intent intent=new Intent ( Intent.action_call,uri.parse ("Tel:" +phone)); PhoneandemailActivity.this.startActivity (intent);}});

② the interface shown after clicking is:

4) The implementation of the function of sending SMS

① Create a Click event to send a text message and use the intent object to pass the contact's number to the Messageactivity interface

Tv_massage.setonclicklistener (New View.onclicklistener () {@Overridepublic void OnClick (View v) {Intent intent=new Intent (Phoneandemailactivity.this, Massageactivity.class); Intent.putextra ("Userphone", phone); StartActivity ( Intent);});

The construction of ②messageactivity interface

③ program implementation of the function of sending SMS

A. Use the intent object to get the information passed through the Phoneandemailactitvity interface.

B. Create a sent Click event Send_btn.setonclicklistener (this);

@Overridepublic void OnClick (View v) {int id=v.getid (); switch (ID) {Case r.id.send_btn:string Phonenum=et_phone.gettext (). toString (); String Content=et_content.gettext (). toString (); if (Textutils.isempty (content)) {Toast.maketext (this, R.string.error_sms_content, Toast.length_short). Show ();} Else{smsmanager Smsmanager=smsmanager.getdefault (); Arraylist<string> message = smsmanager.dividemessage (content); for (int i=0;i<message.size (); i++) { Smsmanager.sendtextmessage (Phonenum, Null,message.get (i), NULL, NULL);} Toast.maketext (This, r.string.success_sms_content, Toast.length_long). Show ();} Break;default:break;}

C. Achieving results
