Intent惯用调用代码

Intent常用调用代码

 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_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);

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);
