android系统自带的intent集锦

首先请参看： 《精》Intent各种跳转 Android中常用方法集锦：
1、设置应用当前语言 /** *设置应用当前语言，如： lan=""(表示当前系统语言)， lan=" zh"(中文)， lan=" ja"(日语) * @paramlan */ publicvoidsetLanguage(Stringlan){ Localelocale= newLocale(lan); Locale. setDefault(locale); Configurationconfig= newConfiguration(); config.locale=locale; getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics()); } 2、重启Activity /** *重启Activity,很是巧妙 */ publicvoidreload(){
Intentintent=getIntent(); overridePendingTransition(0,0); intent.addFlags(Intent. FLAG_ACTIVITY_NO_ANIMATION); finish();
overridePendingTransition(0,0); startActivity(intent); } 3、更改系统亮度 /** *更改系统亮度 * @paramvalue */ publicvoidchangeBrightness( intvalue){ System. putInt(getContentResolver(),System. SCREEN_BRIGHTNESS,value); LayoutParamslayoutpars=getWindow().getAttributes(); layoutpars.screenBrightness=value/( float)255; getWindow().setAttributes(layoutpars); } 4、设置全屏 /** *设置全屏 */ protectedvoidsetFullScreen(){ getWindow().requestFeature(Window. FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams. FLAG_FULLSCREEN,WindowManager.LayoutParams. FLAG_FULLSCREEN); } 5、打开网页（ recommended_url在strings.xml文件中配置的，如：http://www.baidu.com） ButtonbuttonRecommended=(Button)findViewById(R.id. buttonRecommended); buttonRecommended.setOnClickListener( newOnClickListener(){ @Override publicvoidonClick(Viewv){ finalIntentintent= newIntent(Intent. ACTION_VIEW,Uri. parse(getString(R.string. recommended_url))); startActivity(intent); } });
6、打开系统相册 privatevoidpicture(){ finalIntentimageIntent= newIntent(Intent. ACTION_PICK,android.provider.MediaStore.Images.Media. INTERNAL_CONTENT_URI); imageIntent.setType("image/*"); startActivityForResult(imageIntent, REQUEST_CODE_CAMERA); } 7、启动拍照 publicvoidstartCamera(){ filename=(imageList.size()+1)+".jpg"; pictureUri=Uri. fromFile( newFile(fileUri,filename)); if(sp== null) sp=getPreferences( MODE_PRIVATE); Editoreditor=sp.edit(); editor.putString("pictureUri",pictureUri.toString()); editor.commit(); Intentintent= newIntent(); intent.setAction("android.media.action.IMAGE_CAPTURE"); intent.putExtra(MediaStore. EXTRA_OUTPUT,pictureUri); startActivityForResult(intent, REQUEST_CODE_CAMERA_SHOOT); }

/**

*照相功能

privatevoidcameraMethod(){

IntentimageCaptureIntent=newIntent(MediaStore.ACTION_IMAGE_CAPTURE);

strImgPath=Environment.getExternalStorageDirectory().toString()+"/CONSDCGMPIC/";//存放照片的文件夹

StringfileName=newSimpleDateFormat("yyyyMMddHHmmss").format(newDate())+".jpg";//照片命名

Fileout=newFile(strImgPath);

if(!out.exists()){

out.mkdirs();

}

out=newFile(strImgPath,fileName);

strImgPath=strImgPath+fileName;//该照片的绝对路径

Uriuri=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);

}

8、启动录像 publicvoidstartVideo(){ filename="video_template"+System. currentTimeMillis()+".mp4"; videoUri=Uri. fromFile( newFile(fileUri,filename)); if(sp== null){ sp=getPreferences( MODE_PRIVATE); } Editoreditor=sp.edit(); editor.putString("videoUri",videoUri.toString()); IntentmIntent= null; mIntent= newIntent(); mIntent.setAction("android.media.action.VIDEO_CAPTURE"); //mIntent.putExtra(MediaStore.EXTRA_OUTPUT,videoUri); //mIntent=newIntent(MediaStore.ACTION_VIDEO_CAPTURE); //mIntent.putExtra(MediaStore.EXTRA_OUTPUT,videoUri);//指定照片存放路径，默认是在/mnt/sdcard/DICM/Camera/目录下， // //mIntent.putExtra("android.intent.extra.sizeLimit",999999999L); //mIntent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY,0);//0表示lowQuality //mIntent.putExtra("android.intent.extra.durationLimit",3600); startActivityForResult(mIntent, REQUEST_CODE_VIDEO_SHOOT);

}

9、拍摄视频

privatevoidvideoMethod(){

Intentintent=newIntent(MediaStore.ACTION_VIDEO_CAPTURE);

intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY,0);

startActivityForResult(intent,REQUEST_CODE_TAKE_VIDEO);

}

10、启动录音

/**

*录音功能

privatevoidsoundRecorderMethod(){

Intentintent=newIntent(Intent.ACTION_GET_CONTENT);

intent.setType("audio/amr");

startActivityForResult(intent,RESULT_CAPTURE_RECORDER_SOUND);

}

11、取得系统中所有的Audio文件（AudioInfo是自定义的bean类）： publicAudioInfogetMp3Info(StringaudioPath){ Stringselection=MediaStore.Audio.Media. DATA+"like?";//likeStringpath="/ mnt/ sdcard/music"; String[]selectionArgs={"%"+audioPath+"%"}; String[]projection={ //MediaStore.Audio.Media._ID, MediaStore.Audio.Media. TITLE, MediaStore.Audio.Media. ARTIST, MediaStore.Audio.Media. ALBUM, MediaStore.Audio.Media. DURATION, MediaStore.Audio.Media. SIZE, MediaStore.Audio.Media. DISPLAY_NAME, MediaStore.Audio.Media. DATA//-->FileFullPath }; Cursorcursor= null; cursor=managedQuery(MediaStore.Audio.Media. EXTERNAL_CONTENT_URI,projection,selection,selectionArgs, null); //cursor=managedQuery(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,projection,null,null,null);//selectallaudiofile //Cursorcursor2=query(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,null,null,null,MediaStore.Audio.Media.DEFAULT_SORT_ORDER) AudioInfoaudioInfo= newAudioInfo(); for(cursor.moveToFirst();!cursor.isAfterLast();cursor.moveToNext()){ audioInfo.setTitle(cursor.getString(0).toString()); audioInfo.setArtist(cursor.getString(1).toString()); audioInfo.setAlbum(cursor.getString(2).toString()); audioInfo.setDuration(cursor.getString(3).toString()); audioInfo.setSize(cursor.getString(4).toString()); audioInfo.setFilename(cursor.getString(5).toString()); audioInfo.setFilePath(cursor.getString(6).toString()); Log. e( LOG,audioInfo.toString()+","+cursor.getString(5).toString()+","+cursor.getString(6).toString()); } returnaudioInfo; }
注：取得视频文件的信息有点类似 12、发送电子邮件：

//youneedconfigthemailappinyourandroidmoblefirst,andthemailwillsendbythemailapp.andthereareonebigbug:

//youcan'tsendthemailSilentlyandyouneedtoclickthesendbutton

//第一种方法是调用了系统的mailapp，你首先要配置系统的mailapp，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

publicintsendMailByIntent(){

String[]reciver=newString[]{"181712000@qq.com"};

String[]mySbuject=newString[]{"test"};

StringmyCc="cc";

Stringmybody="测试EmailIntent";

IntentmyIntent=newIntent(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,"mailtest"));

return1;

}

//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。

publicintsendMailByJavaMail(){

Mailm=newMail("wcfXXXX@gmail.com","XXXXX");

m.set_debuggable(true);

String[]toArr={"18170000@qq.com"};

m.set_to(toArr);

m.set_from("18170000@qq.com");

m.set_subject("ThisisanemailsentusingicetestfromanAndroiddevice");

//Toast.makeText(MailApp.this,

//"Therewasaproblemsendingtheemail.",

//Toast.LENGTH_LONG).show();

Log.e("MailApp","Couldnotsendemail",e);

}

return1;

}

13、打电话发短信：调用打电话和发短信功能(ANDROID)
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：
Intentintent=newIntent();
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
IntentmyIntentDial=newIntent(Intent.ACTION_CALL,Uri.parse("tel:"+mobile));
startActivity(myIntentDial); 调用拨打电话界面：
Intentintent=newIntent();
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); 或者 IntentmyIntentDial=newIntent(Intent.ACTION_DIAL,Uri.parse("tel:"+mobile)); startActivity(myIntentDial); 需要添加打电话权限：
<uses-permissionAndroid: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：
SmsManagersmsManager=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(Stringtext: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）
UrismsToUri=Uri.parse("smsto:10086");
IntentmIntent=newIntent(android.content.Intent.ACTION_SENDTO,smsToUri);
mIntent.putExtra("sms_body","TheSMStext");
startActivity(mIntent);

b.调用系统已发送短信界面
UrismsUri=Uri.parse("smsto:106900867734");
Intentintent=newIntent(Intent.ACTION_MAIN,smsUri);
intent.setType("vnd.android-dir/mms-sms");
startActivity(intent);
15、全屏、亮度、模糊度设置 //设置窗体全屏
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);
