Android Intent用法详解

如果是从BroadcastReceiver 启动一个新的Activity , 不要忘记i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

public class MyReceiver extends BroadcastReceiver{
public static final String action=”acc”;
public void onReceive(Context context, Intent intent) {
Intent i=new Intent(context,Receivered.class);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}

1. 指定act ion 和type
// SIM import

Intent importIntent = new Intent(Intent.ACTION_VIEW);
importIntent.setType(“vnd.android.cursor.item/sim-contact”);
importIntent.setClassName(“com.android.phone”, “com.android.phone.SimContacts”);
menu.add(0, 0, 0, R.string.importFromSim)
.setIcon(R.drawable.ic_menu_import_contact)
.setIntent(importIntent);

2. 指定act ion, da ta和type
(1)隐式查找type
示例代码：

uri: content://simcontacts/simPeople/(id)
intent = new Intent(“android.intent.action.SIMEDIT”,uri);
startActivity(intent);

程序会根据data中的uri去查找匹配的type（必须的）
provider中的getType()
case SIM_PEOPLE_ID:
return “vnd.android.cursor.item/sim-contact”;
配置文件中的filter设定
AndroidManifest.xml
也可以自己设定type，但只能使用 setDataAndType()
3. 其他设定intent的属性方式

Intent setComponent(ComponentName component)
Intent setClassName(Context packageContext, String className)
Intent setClassName(String packageName, String className)
Intent setClass(Context packageContext, Class cls)

打开其他APK文件的ACTIVITY

Intent mIntent = new Intent();
ComponentName comp = new ComponentName(“com.android.a”,”com.android.a.AbcActivity” );
mIntent.setComponent(comp);
mIntent.setAction(“android.intent.action.MAIN”);
startActivity(mIntent);

显示网页:

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

显示地图:

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

路径规划:
1. Uri uri = Uri.parse(“http://maps.google.com/maps?f=d&saddr=startLat%20startLng&daddr=endLat%20endLng&hl=en”);
2. Intent it = new Intent(Intent.ACTION_VIEW,URI);
3. startActivity(it);
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);

直接拨号

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权限
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);

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Email

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”));

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”));

播放多媒体
//方法1.

Uri uri = Uri.parse(“file:///sdcard/song.mp3″);
Intent it = new Intent(Intent.ACTION_VIEW, uri);
// it.addFlags(it.FLAG_ACTIVITY_NEW_TASK);//非必须选项
it.setDataAndType(uri, “audio/mp3″);
context.startActivity(it);

//方法2.

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

//方法3. 启动一个播放器并播放一个系统声音

Uri uri = Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, “1″);
 Intent it = new Intent(Intent.ACTION_VIEW, uri);
 startActivity(it);
Uninstall 程序
 Uri uri = Uri.fromParts(“package”, strPackageName, null);
 Intent it = new Intent(Intent.ACTION_DELETE, uri);
 startActivity(it);

uninstall apk

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

install apk

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

play audio

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

哈，原来你还没贴完，我再加个:
//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”));

market相关
//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);
