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);程序会很据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ACTIVITYIntent 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:
1. Uri uri = Uri.parse(“http://www.google.com”);
2. Intent it = new Intent(Intent.ACTION_VIEW,uri);
3. startActivity(it);
显示地图:
1. Uri uri = Uri.parse(“geo:38.899533,-77.036476″);
2. Intent it = new Intent(Intent.Action_VIEW,uri);
3. 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1. Uri uri = Uri.parse(“tel:xxxxxx”);
2. Intent it = new Intent(Intent.ACTION_DIAL, uri);
3. startActivity(it);
1. Uri uri = Uri.parse(“tel.xxxxxx”);
2. Intent it =new Intent(Intent.ACTION_CALL,uri);
3. 要使用这个必须在配置文件中加入
发送SMS/MMS
调用发送短信的程序1. Intent it = new Intent(Intent.ACTION_VIEW);
2. it.putExtra(“sms_body”, “The SMS text”);
3. it.setType(“vnd.android-dir/mms-sms”);
4. startActivity(it);

it.setDataAndType(uri, “audio/mp3″);
context.startActivity(it);//方法2.
1.
2. Intent it = new Intent(Intent.ACTION_VIEW);
3. Uri uri = Uri.parse(“file:///sdcard/song.mp3″);
4. it.setDataAndType(uri, “audio/mp3″);
5. startActivity(it);
//方法3. 启动一个播放器并播放一个系统声音

market相关1. //搜索应用
2. Uri uri = Uri.parse(“market://search?q=pname:pkg_name”);
3. Intent it = new Intent(Intent.ACTION_VIEW, uri);
4. startActivity(it);
5. //where pkg_name is the full package path for an application
7. //显示指定应用的详细页面（这个好像不支持了，找不到app_id）
8. Uri uri = Uri.parse(“market://details?id=app_id”);
9. Intent it = new Intent(Intent.ACTION_VIEW, uri);
10. startActivity(it);
Uninstall 应用程序
