Android Intent的几种用法全面总结

2010-09-14 09:48

Intent 应该算是Android中特有的东西。你可以在Intent中指定程序要执行的动作（比如：view,edit,dial），以及程序执行到该动作时所需 要的资料。都指定好后，只要调用startActivity()，Android系统会自动寻找最符合你指定要求的应用程序，并执行该程序。

下面列出几种Intent的用法
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:
Uri uri = Uri.parse(“http://maps.google.com/maps?f=d&saddr=startLat%20startLng&daddr=endLat%20endLng&hl=en “);
Intent it = new Intent(Intent.ACTION_VIEW,URI);
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);

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

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

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

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);

//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);
//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

2.Android Activity和Intent机制学习笔记

**Intent用法实例

1.无参数Activity跳转**

1. Intent it = new Intent(Activity.Main.this, Activity2.class);
2. startActivity(it);

2.向下一个Activity传递数据（使用Bundle和Intent.putExtras）

1. Intent it = new Intent(Activity.Main.this, Activity2.class);
2. Bundle bundle=new Bundle();
3. bundle.putString(“name”, “This is from MainActivity!”);
4. it.putExtras(bundle); // it.putExtra(“test”, “shuju”);
5. startActivity(it); // startActivityForResult(it,REQUEST_CODE);

对于数据的获取可以采用：

1. Bundle bundle=getIntent().getExtras();
2. String name=bundle.getString(“name”);

3.向上一个Activity返回结果（使用setResult，针对startActivityForResult(it,REQUEST_CODE)启动的Activity）

1. Intent intent=getIntent();
2. Bundle bundle2=new Bundle();
3. bundle2.putString(“name”, “This is from ShowMsg!”);
4. intent.putExtras(bundle2);
5. setResult(RESULT_OK, intent);

4.回调上一个Activity的结果处理函数（onActivityResult）

1. @Override
2. protected void onActivityResult(int requestCode, int resultCode, Intent data) {
3. // TODO Auto-generated method stub
4. super.onActivityResult(requestCode, resultCode, data);
5. if (requestCode==REQUEST_CODE){
6. if(resultCode==RESULT_CANCELED)
7. setTitle(“cancle”);
8. else if (resultCode==RESULT_OK) {
9. String temp=null;
10. Bundle bundle=data.getExtras();
11. if(bundle!=null) temp=bundle.getString(“name”);
12. setTitle(temp);
13. }
14. }
15. }
