Android Intent的几种用法全面总结

Intent, 用法

Intent应该算是Android中特有的东西。你可以在Intent中指定程序要执行的动作（比如：view,edit,dial），以及程序执行到该动作时所需要的资料。都指定好后，只要调用startActivity()，Android系统会自动寻找最符合你指定要求的应用程序，并执行该程序。 下面列出几种Intent的用法 显示网页: Uri uri = Uri.parse("http://www.google.com"); Intent it  = new Intent(Intent.ACTION_VIEW,uri); startActivity(it); 复制代码 显示地图: Uri uri = Uri.parse("geo:38.899533,-77.036476"); Intent it = new Intent(Intent.Action_VIEW,uri); startActivity(it); 复制代码 路径规划: Uri uri = Uri.parse("http://maps.google.com/maps?f=d&saddr=startLat%20startLng&daddr=endLat%20endLng&hl=en"); Intent it = new Intent(Intent.ACTION_VIEW,URI); startActivity(it); 复制代码 拨打电话: 调用拨号程序 Uri uri = Uri.parse("tel:xxxxxx"); Intent it = new Intent(Intent.ACTION_DIAL, uri);   startActivity(it);   复制代码 Uri uri = Uri.parse("tel.xxxxxx"); Intent it =new Intent(Intent.ACTION_CALL,uri); 要使用这个必须在配置文件中加入<uses-permission id="android.permission.CALL_PHONE" /> 复制代码 发送SMS/MMS 调用发送短信的程序 Intent it = new Intent(Intent.ACTION_VIEW);    it.putExtra("sms_body", "The SMS text");    it.setType("vnd.android-dir/mms-sms");    startActivity(it);   复制代码 发送短信 Uri uri = Uri.parse("smsto:0800000123");    Intent it = new Intent(Intent.ACTION_SENDTO, uri);    it.putExtra("sms_body", "The SMS text");    startActivity(it);   复制代码 发送彩信 Uri uri = Uri.parse("content://media/external/images/media/23");    Intent it = new Intent(Intent.ACTION_SEND);    it.putExtra("sms_body", "some text");    it.putExtra(Intent.EXTRA_STREAM, uri);    it.setType("image/png");    startActivity(it); 复制代码 发送Email Uri uri = Uri.parse("mailto:xxx@abc.com"); Intent it = new Intent(Intent.ACTION_SENDTO, uri); startActivity(it); 复制代码 Intent it = new Intent(Intent.ACTION_SEND);    it.putExtra(Intent.EXTRA_EMAIL, "me@abc.com");    it.putExtra(Intent.EXTRA_TEXT, "The email body text");    it.setType("text/plain");    startActivity(Intent.createChooser(it, "Choose Email Client"));   复制代码 Intent it=new Intent(Intent.ACTION_SEND);      String[] tos={"me@abc.com"};      String[] ccs={"you@abc.com"};      it.putExtra(Intent.EXTRA_EMAIL, tos);      it.putExtra(Intent.EXTRA_CC, ccs);      it.putExtra(Intent.EXTRA_TEXT, "The email body text");      it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text");      it.setType("message/rfc822");      startActivity(Intent.createChooser(it, "Choose Email Client"));    复制代码 添加附件 Intent it = new Intent(Intent.ACTION_SEND);    it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text");    it.putExtra(Intent.EXTRA_STREAM, "file:///sdcard/mysong.mp3");    sendIntent.setType("audio/mp3");    startActivity(Intent.createChooser(it, "Choose Email Client")); 复制代码 播放多媒体    Intent it = new Intent(Intent.ACTION_VIEW); Uri uri = Uri.parse("file:///sdcard/song.mp3"); it.setDataAndType(uri, "audio/mp3"); startActivity(it); 复制代码 Uri uri = Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, "1");    Intent it = new Intent(Intent.ACTION_VIEW, uri);    startActivity(it);   复制代码 Uninstall 程序 Uri uri = Uri.fromParts("package", strPackageName, null);    Intent it = new Intent(Intent.ACTION_DELETE, uri);    startActivity(it); 复制代码

uninstall apk

Uri uninstallUri = Uri.fromParts("package", "xxx", null);

returnIt = new Intent(Intent.ACTION_DELETE, uninstallUri);

复制代码

install apk

Uri installUri = Uri.fromParts("package", "xxx", null);

returnIt = new Intent(Intent.ACTION_PACKAGE_ADDED, installUri);

复制代码

play audio

Uri playUri = Uri.parse("file:///sdcard/download/everything.mp3");

returnIt = new Intent(Intent.ACTION_VIEW, playUri);

复制代码

//发送附件
Intent it = new Intent(Intent.ACTION_SEND);  
it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text");  
it.putExtra(Intent.EXTRA_STREAM, "file:///sdcard/eoe.mp3");  
sendIntent.setType("audio/mp3");  
startActivity(Intent.createChooser(it, "Choose Email Client"));

//搜索应用
Uri uri = Uri.parse("market://search?q=pname:pkg_name");  
Intent it = new Intent(Intent.ACTION_VIEW, uri);  
startActivity(it);  
//where pkg_name is the full package path for an application  

//显示指定应用的详细页面（这个好像不支持了，找不到app_id）
Uri uri = Uri.parse("market://details?id=app_id");  
Intent it = new Intent(Intent.ACTION_VIEW, uri);  
startActivity(it);  
//where app_id is the application ID, find the ID  
//by clicking on your application on Market home  
//page, and notice the ID from the address bar
