我开始学习如何为 Android 开发应用程序，但我在 Intent 方面遇到了一些问题——它们似乎根本没有记录。我想要做的就是将用户发送到录像机，他们在那里录制视频，并将视频信息返回到我的应用程序。我知道这是可能的，正如我在其他应用程序中看到的那样，但似乎没有记录 Intent (或者我只是不完全理解 Intent 的工作原理)。

有什么想法吗？

最佳答案

除了上述解决方案，这里还有一些常见的 Intent

//显示网页 Intent :

Uri uri = Uri.parse("http://www.google.com");
Intent it  = new Intent(Intent.ACTION_VIEW,uri);
startActivity(it);

//显示 map Intent :

Uri uri = Uri.parse("geo:38.899533,-77.036476");
Intent it = new Intent(Intent.Action_VIEW,uri);
startActivity(it); 

//显示方法

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);

//调用拨号程序

Uri uri = Uri.parse("tel:xxxxxx");
Intent it = new Intent(Intent.ACTION_DIAL, uri);  
startActivity(it);  

Uri uri = Uri.parse("tel.xxxxxx");
Intent it =new Intent(Intent.ACTION_CALL,uri);
//don't forget add this config:<uses-permission id="android.permission.CALL_PHONE" />

//发送短信/彩信，调用发送程序

Intent it = new Intent(Intent.ACTION_VIEW);   
it.putExtra("sms_body", "The SMS text");   
it.setType("vnd.android-dir/mms-sms");   
startActivity(it);  

//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);  

//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); 

//发送邮件

Uri uri = Uri.parse("mailto:xxx@abc.com");
Intent it = new Intent(Intent.ACTION_SENDTO, uri);
startActivity(it);

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"));  

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"));   


//add extra
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"));

//播放媒体

Intent it = new Intent(Intent.ACTION_VIEW);
Uri uri = Uri.parse("file:///sdcard/song.mp3");
it.setDataAndType(uri, "audio/mp3");
startActivity(it);

Uri uri = Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, "1");   
Intent it = new Intent(Intent.ACTION_VIEW, uri);   
startActivity(it);  

//卸载

Uri uri = Uri.fromParts("package", strPackageName, null);   
Intent it = new Intent(Intent.ACTION_DELETE, uri);   
startActivity(it);

//卸载apk

Uri uninstallUri = Uri.fromParts("package", "xxx", null);
returnIt = new Intent(Intent.ACTION_DELETE, uninstallUri);

//安装apk

Uri installUri = Uri.fromParts("package", "xxx", null);
returnIt = new Intent(Intent.ACTION_PACKAGE_ADDED, installUri);

//播放音频

Uri playUri = Uri.parse("file:///sdcard/download/everything.mp3");
returnIt = new Intent(Intent.ACTION_VIEW, playUri);

//发送额外的

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

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  

//显示程序详情页

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

//搜索谷歌

Intent intent = new Intent();
intent.setAction(Intent.ACTION_WEB_SEARCH);
intent.putExtra(SearchManager.QUERY,"searchString")
startActivity(intent);
