android intent和intent action大全

1.Intent的用法：

(1)用Action跳转

1、使用Action跳转，如果有一个程序的AndroidManifest.xml中的某一个 Activity的IntentFilter段中定义了包含了相同的Action那么这个Intent就与这个目标Action匹配。如果这个IntentFilter段中没有定义 Type,Category，那么这个 Activity就匹配了。但是如果手机中有两个以上的程序匹配，那么就会弹出一个对话可框来提示说明。

Action 的值在Android中有很多预定义，如果你想直接转到你自己定义的Intent接收者，你可以在接收者的IntentFilter 中加入一个自定义的Action值（同时要设定 Category值为"android.intent.category.DEFAULT"），在你的Intent中设定该值为Intent的 Action,就直接能跳转到你自己的Intent接收者中。因为这个Action在系统中是唯一的。

2,data/type，你可以用Uri 来做为data,比如Uri uri = Uri.parse(http://www.google.com);

Intent i = new Intent(Intent.ACTION_VIEW,uri);手机的Intent分发过程中，会根据http://www.google.com 的scheme判断出数据类型type 。手机的Brower则能匹配它，在Brower的Manifest.xml中的IntenFilter中首先有ACTION_VIEW Action,也能处理http:的type，

3，至于分类Category，一般不要去在Intent中设置它，如果你写Intent的接收者，就在Manifest.xml的Activity的 IntentFilter中包含android.category.DEFAULT,这样所有不设置 Category（Intent.addCategory(String c);）的Intent都会与这个Category匹配。

4,extras（附加信息），是其它所有附加信息的集合。使用extras可以为组件提供扩展信息，比如，如果要执行“发送电子邮件”这个动作，可以将电子邮件的标题、正文等保存在extras里，传给电子邮件发送组件。

（2）用类名跳转

Intent负责对应用中一次操作的动作、动作涉及数据、附加数据进行描述，Android则根据此Intent的描述，负责找到对应的组件，将 Intent传递给调用的组件，并完成组件的调用。Intent在这里起着实现调用者与被调用者之间的解耦作用。Intent传递过程中，要找到目标消费者（另一个Activity,IntentReceiver或Service），也就是Intent的响应者。

Intent intent = new Intent();

intent.setClass(context, targetActivy.class);

//或者直接用 Intent intent = new Intent(context, targetActivity.class);

startActivity(intent);

不过注意用类名跳转，需要在AndroidManifest.xml中申明activity

2.几种Intent的用法

android 中intent是经常要用到的。不管是页面牵转，还是传递数据，或是调用外部程序，系统功能都要用到intent。在做了一些intent的例子之后，整理了一下intent，希望对大家有用。由于intent内容太多，不可能真的写全，难免会有遗落，以后我会随时更新。如果你们有疑问或新的intent内容，希望交流。

i.setComponent(cn);

i.setAction("android.intent.action.MAIN");

startActivityForResult(i, RESULT_OK);

20 添加到短信收件箱

ContentValues cv = new ContentValues();

cv.put("type", "1");

cv.put("address","短信地址");

cv.put("body", "短信内容");

getContentResolver().insert(Uri.parse("content://sms/inbox"), cv);

21 从sim卡或者联系人中查询

Cursor cursor;

Uri uri;

if (type == 1) {

Intent intent = new Intent();

intent.setData(Uri.parse("content://icc/adn"));

uri = intent.getData();

} else

uri = People.CONTENT_URI;

cursor = activity.getContentResolver().query(uri, null, null, null, null);

while (cursor.moveToNext()) {

int peopleId = cursor.getColumnIndex(People._ID);

int nameId = cursor.getColumnIndex(People.NAME);

int phoneId = cursor.getColumnIndex(People.NUMBER);}

查看某个联系人，当然这里是ACTION_VIEW，如果为选择并返回action改为ACTION_PICK，当然处理intent时返回需要用到 startActivityforResult

Uri personUri = ContentUris.withAppendedId(People.CONTENT_URI, ID);//最后的ID参数为联系人Provider中的数据库BaseID，即哪一行

Intent intent = new Intent(); intent.setAction(Intent.ACTION_VIEW); intent.setData(personUri); startActivity(intent);

22 删除

uri = ContentUris.withAppendedId(People.CONTENT_URI, 联系人id);

int count = activity.getContentResolver().delete(uri, null, null

23 添加到联系人：

ContentValues cv = new ContentValues();

ArrayList<ContentProviderOperation> operationList = new ArrayList<ContentProviderOperation>();

ContentProviderOperation.Builder builder = ContentProviderOperation.newInsert(RawContacts.CONTENT_URI);

builder.withValues(cv);

operationList.add(builder.build());

builder = ContentProviderOperation.newInsert(Data.CONTENT_URI);

builder.withValueBackReference(StructuredName.RAW_CONTACT_ID, 0);

builder.withValue(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE);

builder.withValue(StructuredName.DISPLAY_NAME, "自定义联系人名");

builder.withValueBackReference(Phone.RAW_CONTACT_ID, 0);

builder.withValue(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE);

builder.withValue(Phone.NUMBER, "联系人的phonenumber");

builder.withValue(Data.IS_PRIMARY, 1);

try {

getContentResolver().applyBatch(ContactsContract.AUTHORITY, operationList);

} catch (RemoteException e) {

e.printStackTrace();

} catch (OperationApplicationException e) {

}

23 选择一个图片

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);

intent.addCategory(Intent.CATEGORY_OPENABLE);

intent.setType("image/*");

startActivityForResult(intent, 0);

24 调用

Android

设备的照相机，并设置拍照后存放位置

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Environment .getExternalStorageDirectory().getAbsolutePath()+"/cwj", android123 + ".jpg"))); //存放位置为sdcard卡上cwj文件夹，文件名为android123.jpg格式

startActivityForResult(intent, 0);

25 在market上搜索指定package name，比如搜索com.android123.cwj的写法如下

Uri uri = Uri.parse("market://search?q=pname:com.android123.cwj");

Intent intent = new Intent(Intent.ACTION_VIEW, uri); startActivity(intent);

26获取文件信息，并使用相对应软件打开

private void openFile(File f)

{

Intent intent = new Intent();

intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

intent.setAction(android.content.Intent.ACTION_VIEW);

String type = getMIMEType(f);

intent.setDataAndType(Uri.fromFile(f), type);

startActivity(intent);

}

private String getMIMEType(File f){

String end = f

.getName()

.substring(f.getName().lastIndexOf(".") + 1,

f.getName().length()).toLowerCase();

String type = "";

if (end.equals("mp3") || end.equals("aac") || end.equals("aac")

|| end.equals("amr") || end.equals("mpeg")

|| end.equals("mp4"))

{

type = "audio";

} else if (end.equals("jpg") || end.equals("gif")

|| end.equals("png") || end.equals("jpeg"))

type = "image";

} else

type = "*";

}

type += "/*";

return type;
