Intent常用调用代码

显示Web网页:

Uri uri = Uri.parse("http://www.android123.com.cn");  
  
Intent it =new Intent(Intent.ACTION_VIEW,uri);  
  
startActivity(it); 

显示Google地图:

Uri uri = Uri.parse("geo:38.899533,-77.036476");  
  
Intent it =new Intent(Intent.Action_VIEW,uri);  
  
startActivity(it);  

Maps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:

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);  

注意需要权限

<uses-permission id="android.permission.CALL_PHONE"/>

发送SMS/MMS

Intent it =new Intent(Intent.ACTION_VIEW);  
  
it.putExtra("sms_body", "android开发网欢迎您");  
  
it.setType("vnd.android-dir/mms-sms");  
  
startActivity(it);   

发送短信

Uri uri = Uri.parse("smsto:10086");  
  
 Intent it =new Intent(Intent.ACTION_SENDTO, uri);  
  
 it.putExtra("sms_body", "10086"); //正文为10086  
  
 startActivity(it);     

发送彩信

Uri uri = Uri.parse("content://media/external/images/media/10"); //该Uri根据实际情况修改，external代表外部存储即sdcard  
  
 Intent it =new Intent(Intent.ACTION_SEND);  
  
 it.putExtra("sms_body", "android123.com.cn");  
  
 it.putExtra(Intent.EXTRA_STREAM, uri);  
  
 it.setType("image/png");  
  
 startActivity(it);  

发送Email

Uri uri = Uri.parse("mailto:android123@163.com");  
  
 Intent it =new Intent(Intent.ACTION_SENDTO, uri);  
  
 startActivity(it);  

Intent it =new Intent(Intent.ACTION_SEND);  
  
 it.putExtra(Intent.EXTRA_EMAIL, "android123@163.com");  
  
 it.putExtra(Intent.EXTRA_TEXT, "android开发网测试");  
  
 it.setType("text/plain");  
  
 startActivity(Intent.createChooser(it, "选择一个Email客户端"));     

Intent it=new Intent(Intent.ACTION_SEND);    
  
 String[] tos={"android123@163.com"};     //发送到  
  
 String[] ccs={"ophone123@163.com"};    //抄送  
  
 it.putExtra(Intent.EXTRA_EMAIL, tos);    
  
 it.putExtra(Intent.EXTRA_CC, ccs);    
  
 it.putExtra(Intent.EXTRA_TEXT, "正文");    
  
 it.putExtra(Intent.EXTRA_SUBJECT, "标题");    
  
 it.setType("message/rfc822");    //编码类型  
  
 startActivity(Intent.createChooser(it, "选择一个Email客户端"));  

Email添加附件

Intent it = new Intent(Intent.ACTION_SEND);  
  
it.putExtra(Intent.EXTRA_SUBJECT, "正文");  
  
it.putExtra(Intent.EXTRA_STREAM, "file:///sdcard/nobody.mp3"); //附件为sd卡上的nobody MP3文件  
  
sendIntent.setType("audio/mp3");  
  
startActivity(Intent.createChooser(it, "选择一个Email客户端"));  

播放多媒体

Intent it = new Intent(Intent.ACTION_VIEW);  
  
Uri uri = Uri.parse("file:///sdcard/nobody.mp3");  
  
it.setDataAndType(uri, "audio/mp3");  
  
startActivity(it);  
  
Uri uri = Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, "1"); //从系统内部的MediaProvider索引中调用播放  
  
Intent it = new Intent(Intent.ACTION_VIEW, uri);  
  
startActivity(it);     

Uninstall卸载程序

Uri uri = Uri.fromParts("package", packageName, null); //packageName为包名，比如com.android123.apkInstaller  
  
Intent it = new Intent(Intent.ACTION_DELETE, uri);  
  
startActivity(it);  

进入联系人界面

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

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);  

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);
