android系统自带的intent集锦
/**
* 照相功能
*/
private void cameraMethod() {
Intent imageCaptureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
strImgPath = Environment.getExternalStorageDirectory().toString() + "/CONSDCGMPIC/";//存放照片的文件夹
String fileName = new SimpleDateFormat("yyyyMMddHHmmss").format(new Date()) + ".jpg";//照片命名
File out = new File(strImgPath);
if (!out.exists()) {
out.mkdirs();
}
out = new File(strImgPath, fileName);
strImgPath = strImgPath + fileName;//该照片的绝对路径
Uri uri = Uri.fromFile(out);
imageCaptureIntent.putExtra(MediaStore.EXTRA_OUTPUT, uri);//指定照片存放路径，默认是在/mnt/sdcard/DICM/Camera/目录下
imageCaptureIntent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(imageCaptureIntent, RESULT_CAPTURE_IMAGE);
}
}
9、 拍摄视频
private void videoMethod() {
Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 0);
startActivityForResult(intent, REQUEST_CODE_TAKE_VIDEO);
}
/**
* 录音功能
*/
private void soundRecorderMethod() {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("audio/amr");
startActivityForResult(intent, RESULT_CAPTURE_RECORDER_SOUND);
}
// you need config the mail app in your android moble first,and the mail will send by the mail app. and there are one big bug:
//you can't send the mail Silently and you need to click the send button
//第一种方法是调用了系统的mail app，你首先要配置系统的mail app，但是这个方法的最大问题是，你运行这个方法后它并不会默认的发送邮件，而是弹出mail的app界面，你需要手动的点击发送
public int sendMailByIntent() {
String[] reciver = new String[] { "[email protected]" };
String[] mySbuject = new String[] { "test" };
String myCc = "cc";
String mybody = "测试Email Intent";
Intent myIntent = new Intent(android.content.Intent.ACTION_SEND);
myIntent.setType("plain/text");
myIntent.putExtra(android.content.Intent.EXTRA_EMAIL, reciver);
myIntent.putExtra(android.content.Intent.EXTRA_CC, myCc);
myIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, mySbuject);
myIntent.putExtra(android.content.Intent.EXTRA_TEXT, mybody);
startActivity(Intent.createChooser(myIntent, "mail test"));
return 1;
}
/*this method can't be used in android mobile successful,but it can run normally in PC.
Because it will cause the java.lang.NoClassDefFoundError: javax.activation.DataHandler error
May be there are some way to solove it ......there are always javax package not found in android virtual mobile.
By the way ,the method use Apache mail jar
*/
//第二种，是调用了apache的common库，在pc上可以正常运行，但是在android虚拟机中会报错java.lang.NoClassDefFoundError: javax.activation.DataHandler error
//javax包无法找到，我看了下这个问题还是比较普遍的，大家普遍表示虚拟机是被阉割的版本，javax好像存在不全，这个实际上就无法运行
public int sendMailByApache() {
try {
HtmlEmail email = new HtmlEmail();
// 这里是发送服务器的名字
email.setHostName("smtp.gmail.com");
// 编码集的设置
email.setTLS(true);
email.setSSL(true);
email.setCharset("gbk");
// 收件人的邮箱
email.addTo("[email protected]");
// 发送人的邮箱
email.setFrom("[email protected]");
// 如果需要认证信息的话，设置认证：用户名-密码。分别为发件人在邮件服务器上的注册名称和密码
email.setAuthentication("wcf1000", "00000");
email.setSubject("测试Email Apache");
// 要发送的信息
email.setMsg("测试Email Apache");
// 发送
email.send();
} catch (EmailException e) {
// TODO Auto-generated catch block
Log.i("IcetestActivity", e.getMessage());
}
return 1;
}
/*
* this method use javamail for android ,it is a good jar,
* you can see the demo in http://www.jondev.net/articles/Sending_Emails_without_User_Intervention_(no_Intents)_in_Android
* and you also need three jars ,which I offered in attachement
*
* */
//第三种，实际是javamail有人做了移植，专门为android做了开发，这下就比较好了，网上的demo代码也比较到位，只有一个问题，就是要自己添加一个mail.java，而且对stmp要手动添加。
//其实理论上还应该有一种，自己实现smtp服务器，全程采用socket编程，直接与目标服务器交流，这个win下面我写过，但是android下就算了，而且长期来讲面临着smtp服务器以后会被进行方向查询，以提高安全性。
public int sendMailByJavaMail() {
Mail m = new Mail("[email protected]", "XXXXX");
m.set_debuggable(true);
String[] toArr = {"[email protected]"};
m.set_to(toArr);
m.set_from("[email protected]");
m.set_subject("This is an email sent using icetest from an Android device");
m.setBody("Email body. test by Java Mail");
try {
//m.addAttachment("/sdcard/filelocation");
if(m.send()) {
Log.i("IcetestActivity","Email was sent successfully.");
} else {
Log.i("IcetestActivity","Email was sent failed.");
}
} catch (Exception e) {
// Toast.makeText(MailApp.this,
// "There was a problem sending the email.",
// Toast.LENGTH_LONG).show();
Log.e("MailApp", "Could not send email", e);
}
return 1;
}
}
1.打电话
可以自己写界面，在button的单击事件中添加如下代码即可：
Intent intent = new Intent();
intent.setAction("android.intent.action.CALL");
intent.setData(Uri.parse("tel:"+ mobile));//mobile为你要拨打的电话号码，模拟器中为模拟器编号也可
startActivity(intent);
或者
startActivity(myIntentDial);
intent.setAction("android.intent.action.DIAL");
intent.setData(Uri.parse("tel:"+ mobile));//mobile为你要拨打的电话号码，模拟器中为模拟器编号也可
startActivity(intent);
<uses-permission Android:name="android.permission.CALL_PHONE" />
14.发短信
和打电话差不多，在button的单击事件中添加如下代码：
SmsManager smsManager = SmsManager.getDefault();
ArrayList<String> texts = smsManager.divideMessage(content);//拆分短信,短信字数太多了的时候要分几次发
for(String text : texts){
smsManager.sendTextMessage(mobile, null, text, null, null);//发送短信,mobile是对方手机号
}
对应发短信权限：
<uses-permissionAndroid:name="android.permission.SEND_SMS" />
附：调用系统 发送短信 和 已发送短信界面
a. 调用系统发送短信界面（并指定短信接收人和短信内容）
Uri smsToUri = Uri.parse("smsto:10086");
Intent mIntent = new Intent( android.content.Intent.ACTION_SENDTO, smsToUri );
mIntent.putExtra("sms_body", "The SMS text");
startActivity( mIntent );
b. 调用系统已发送短信界面
Uri smsUri = Uri.parse("smsto:106900867734");
Intent intent = new Intent(Intent.ACTION_MAIN, smsUri);
intent.setType("vnd.android-dir/mms-sms");
startActivity(intent);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
//设置窗体始终点亮
getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON,
WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
//设置窗体背景模糊
getWindow().setFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND,
WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
