和四大组件关系最紧密的Intent-----意图(二)

一、Intent的扩充：

指定Action,Category调用系统Activity，Intent代表了启动某个程序组件的意图，实际上Intent对象不仅可以启动本应用内程序组件，也可启动Android系统的其他应用的程序组件，包含系统自带的程序组件—只要权限允许。实际上android内部提供了大量标准的Acton,Catetory常量，其中用于启动Activity的标准Action常量及对对应的字符串：

标准的action:

常量 对应字符串 简单说明

ACTION_MAIN android.intent.action.MAIN 应用程序入口

ACTION_VIEW android.intent.action.VIEW 显示指定数据

ACTION_ATTACH_DATE android.intent.action.ATTACH_DATE 指定某快数据将被附加到其他地方

ACTION_EDIT android.intent.action.EDIT 编辑指定数据

ACTION_PICK android.intent.action.PICK 从列表中选择某项，并返回所选的数据

ACTION_CHOOSER android.intent.action.CHOOSER 显示一个Activity选择器

ACTION_GET_CONTENT android.intent.action.GET_CONTENT 让用户选择数据，并返回所选数据

ACTION_DIAL android.intent.action.DIAL 显示拨号面板

ACTION_CALL android.intent.action.CALL 直接向指定用户打电话

ACTION_SEND android.intent.action.SEND 向其他人发送数据

ACTION_SENDTO android.intent.action.SENDTO 向其他人发送信息

ACTION_ANSWER android.intent.action.ANSWER 应答电话

ACTION_INSERT android.intent.action.INSERT 插入数据

ACTION_DELETE android.intent.action.DELETE 删除数据

ACTION_RUN android.intent.action.RUN 运行数据

ACTION_SYNC android.intent.action.SYNC 执行数据同步

ACTION_SEARCH android.intent.action.SEARCH 执行搜索

ACTION_WEB_SEARCH android.intent.action.WEB_SEARCH 执行web搜索

ACTION_FACTORY_TEST android.intent.action.FACTORY_TEST 工厂测试的入口点

Category常量：

CATEGORY_DEFAULT android.intent.category.DEFAULT 默认的Category

CATEGORY_BROWSABLE android.intent.category.BROWSABLE 指定该Activity能被浏览器完全调用

CATEGORY_TAB android.intent.category.TAB 指定该Activity作为TabActivity的Tab页

CATEGORY_LAUNCHER android.intent.category.LAUNCHER 设置该Activity随系统启动而运行

startActivity(it);

12.install apk 安装程序

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

打开照相机

<1>Intent i = new Intent(Intent.ACTION_CAMERA_BUTTON, null);
this.sendBroadcast(i);
<2>long dateTaken = System.currentTimeMillis();
String name = createName(dateTaken) + ".jpg";
fileName = folder + name;
ContentValues values = new ContentValues();
values.put(Images.Media.TITLE, fileName);
values.put("_data", fileName);
values.put(Images.Media.PICASA_ID, fileName);
values.put(Images.Media.DISPLAY_NAME, fileName);
values.put(Images.Media.DESCRIPTION, fileName);

inttPhoto.putExtra(MediaStore.EXTRA_OUTPUT, photoUri);
startActivityForResult(inttPhoto, 10);

14.从gallery选取图片

Intent i = new Intent();

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

刚才找app id未果，结果发现用package name也可以
Uri uri = Uri.parse("market://details?id=<packagename>");
这个简单多了

17寻找应用

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

18打开联系人列表

<2>

Uri uri = Uri.parse("content://contacts/people");
Intent it = new Intent(Intent.ACTION_PICK, uri);
startActivityForResult(it, REQUEST_TEXT);

19 打开另一程序

Intent i = new Intent();
ComponentName cn = new ComponentName("com.yellowbook.android2", "com.yellowbook.android2.AndroidSearch");
i.setComponent(cn);
i.setAction("android.intent.action.MAIN");
startActivityForResult(i, RESULT_OK);

20.调用系统编辑添加联系人（高版本SDK有效）：
