Basic usage examples of intent in Android

Package cn.com. chenzheng_java;

Import Android. App. activity;
Import Android. content. intent;
Import android.net. Uri;
Import Android. OS. Bundle;
Import Android. View. view;
Import Android. View. View. onclicklistener;
Import Android. widget. Button;

Public class intentactivity extends activity {
@ Override
Protected void oncreate (bundle savedinstancestate ){
 
Super. oncreate (savedinstancestate );
Setcontentview (R. layout. Intent );
Button button = (button) findviewbyid (R. Id. button1 );
Button. setonclicklistener (New onclicklistener (){

@ Override
Public void onclick (view v ){

Sentsms2 ();
}
});
 
 
}
 
Uri URI;
Intent intent;
 
/**
* Open the web page. The implicit itent determines who will respond to the intent (no permission is required)
*/
Private void showwebpage (){
Uri = URI. parse ("http://www.baidu.com ");
Intent = new intent (intent. action_view, Uri );
Startactivity (intent );
}
/***
* Open a Web Map (no permission required)
*/
Private void showmap (){
Uri = URI. parse ("http://maps.google.com/maps? F = D & saddr = startlat % 20 startlng & daddr = endlat % 20 endlng & HL = EN ");
Intent = new intent (intent. action_view, Uri );
Startactivity (intent );
}
/***
* Calls out the dialing main program (no permission is required)
*/
Private void caller (){
Uri = URI. parse ("Tel: 5556 ");
Intent = new intent (intent. action_dial, Uri );
Startactivity (intent );

}
/***
* Directly call the phone. Note that you must first grant the permission Android. Permission. call_phone.
*/
Private void call (){
Uri = URI. parse ("Tel: 5556 ");
Intent = new intent (intent. action_call, Uri );
Startactivity (intent );

}
/**
* Call the SMS sending program (no permission required)
*/
Private void sentsms (){

Intent = new intent (intent. action_view );
Intent. putextra ("sms_body", "the SMS text ");
Intent. settype ("Vnd. Android-DIR/MMS-SMS ");
Startactivity (intent );

}
/**
* Send text messages directly (permission Android. Permission. send_sms needs to be declared)
*/
Private void sentsms2 (){

Intent = new intent (intent. action_sendto, Uri );
Intent. putextra ("sms_body", "the SMS text ");
// Intent. settype ("Vnd. Android-DIR/MMS-SMS ");
Startactivity (intent );

}
 
 
}

Send email

Private void sendemail (string number ){
Intent emailintent = new intent ();
Emailintent. setaction (intent. action_send );
Emailintent. settype ("plain/text ");
// Set the address
Emailintent. putextra (intent. extra_email, "chenzheng_java@163.com ");
Emailintent. putextra (intent. extra_subject, "set topic ");
Emailintent. putextra (intent. extra_title, "title ");
Emailintent. putextra (intent. extra_text, "body content: Incoming call, phone number:" + number );
Startactivity (
Intent. createchooser (emailintent, "lainiu, select an application ")
);
Log. I ("notification", "email sent successfully ");
}

Method 2 URI uri = URI. parse ("mailto: terryyhl@gmail.com ");
Intent mymailintent = new intent (intent. action_send, Uri );
Startactivity (mymailintent );

Method 3 intent testintent = new intent (intent. action_send );
String [] TOS = {"terryyhl@gmail.com "};
String [] CCS = {"kalaicheng@hotmail.com "};
Testintent. putextra (intent. extra_email, TOS );
Testintent. putextra (intent. extra_cc, CCS );
Testintent. putextra (intent. extra_text, "this is content ");
Testintent. putextra (intent. extra_subject, "this is the title ");
Testintent. settype ("message/rfc822 ");
Startactivity (intent. createchooser (testintent, "send "));
Method 4: Upload the attachment. Here we use the SD card music file as an example intent testn = new intent (intent. action_send );
Testn. putextra (intent. extra_subject, "title ");
Testn. putextra (intent. extra_stream, "file: // sdcard/musicloud ");
Startactivity (intent. createchooser (testn, "send "));
Use javamail. Here I will not introduce the implementation method of javamail, if you are interested, you can go here to take a look, online to find a more detailed article http://www.javaeye.com/topic/352753
Because the current simulator does not have a built-in Gmail client program, after the e-mail program sends data, the simulator will send "No application can perform this action". I do not have an Android phone
