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:

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);

发送短信

1. Uri uri = Uri.parse(“smsto:0800000123″);

2. Intent it = new Intent(Intent.ACTION_SENDTO, uri);

3. it.putExtra(“sms_body”, “The SMS text”);

4. startActivity(it);

发送彩信

1. Uri uri = Uri.parse(“content://media/external/images/media/23″);

2. Intent it = new Intent(Intent.ACTION_SEND);

3. it.putExtra(“sms_body”, “some text”);

4. it.putExtra(Intent.EXTRA_STREAM, uri);

5. it.setType(“image/png”);

6. startActivity(it);

2. Uri uri = Uri.parse(“mailto:xxx@abc.com”);

3. Intent it = new Intent(Intent.ACTION_SENDTO, uri);

4. startActivity(it);

1. Intent it = new Intent(Intent.ACTION_SEND);

2. it.putExtra(Intent.EXTRA_EMAIL, “me@abc.com”);

3. it.putExtra(Intent.EXTRA_TEXT, “The email body text”);

4. it.setType(“text/plain”);

5. startActivity(Intent.createChooser(it, “Choose Email Client”));

1. Intent it=new Intent(Intent.ACTION_SEND);

2. String[] tos={“me@abc.com”};

3. String[] ccs={“you@abc.com”};

4. it.putExtra(Intent.EXTRA_EMAIL, tos);

5. it.putExtra(Intent.EXTRA_CC, ccs);

6. it.putExtra(Intent.EXTRA_TEXT, “The email body text”);

7. it.putExtra(Intent.EXTRA_SUBJECT, “The email subject text”);

//方法1.

Uri uri = Uri.parse(“file:///sdcard/song.mp3″);

Intent it = new Intent(Intent.ACTION_VIEW, uri);

it.setDataAndType(uri, “audio/mp3″);

context.startActivity(it);

//方法2.

2. Intent it = new Intent(Intent.ACTION_VIEW);

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

1. Uri uri = Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, “1″);

2. Intent it = new Intent(Intent.ACTION_VIEW, uri);

3. startActivity(it);

Uninstall 程序

1. Uri uri = Uri.fromParts(“package”, strPackageName, null);

2. Intent it = new Intent(Intent.ACTION_DELETE, uri);

3. startActivity(it);

uninstall apk

1. Uri uninstallUri = Uri.fromParts(“package”, “xxx”, null);

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

8. Uri uri = Uri.parse(“market://details?id=app_id”);
