Android系统Intent的应用

Android系统Intent的使用
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:[email protected]");

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, "[email protected]");  

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={"[email protected]"};    

String[] ccs={"[email protected]"};    

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
    /** *//**
     * 获得包安装Intent
     * @param tempFile
     * @return
     */
    public static Intent getPackageInstallIntent(File tempFile)
    {
        Uri mPackageURI = Uri.fromFile(tempFile);
        Intent in = new Intent();
        in.setAction(Intent.ACTION_VIEW);
        in.addCategory(Intent.CATEGORY_DEFAULT);
        in
                .setComponent(new ComponentName(
                        "com.android.packageinstaller",
                        "com.android.packageinstaller.PackageInstallerActivity"));
        in.setDataAndType(mPackageURI,
                "application/vnd.android.package-archive");
        in.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        return in;
    }
