**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][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][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<uses-permission id="android.permission.CALL\_PHONE" />  
  
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][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][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][me_abc.com] "\};      
String\[\] ccs=\{"[you@abc.com][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

**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. \}
