关于Contacts的那点事儿

很久没有更新博客了。

一直没整明白，Android中的Contacts是如何组织数据的，于是今天折腾了一下Contacts的结构。

留底以备以后参考。

private String testOne() throws Exception {
    	
    	final Cursor people = getContentResolver().query(Contacts.CONTENT_URI, null, null, null, null);

    	StringBuilder sb = new StringBuilder();
    	while(people.moveToNext()) {
    		long id = people.getLong(people.getColumnIndex(Contacts._ID));
    		String name = people.getString(people.getColumnIndex(PhoneLookup.DISPLAY_NAME));
    		if(id==1) {
    			
    			sb.append("---id is "+id+",name is "+name+"\n");
    			
    			//String IsPhone = people.getString(people.getColumnIndex(Contacts.HAS_PHONE_NUMBER));
    			//if( (Integer.parseInt(IsPhone) > 0) ){}
    			
    			Cursor c = null; 
			// Cursor c = getContentResolver().query(CommonDataKinds.Phone.CONTENT_URI, 
			//		null,CommonDataKinds.Phone.CONTACT_ID+"="+id,null,null);
			//while(c.moveToNext()){
			//	long i = c.getLong(c.getColumnIndex(Contacts._ID));
			//    String num=c.getString(c.getColumnIndex(CommonDataKinds.Phone.NUMBER));
			//    sb.append("phone=id:"+i+", n:"+num+"\n");
			//}
			//c.close();
    			
    			c=getContentResolver().query(Data.CONTENT_URI, null, Data.CONTACT_ID+"="+id, null, null);
    			while(c.moveToNext()){
    				long j=c.getLong(c.getColumnIndex(Contacts._ID));
    				String typ=c.getString(c.getColumnIndex(Data.MIMETYPE));
    				String str="";
    				if(typ.equals(CommonDataKinds.Im.CONTENT_ITEM_TYPE)){
    					str=c.getString(c.getColumnIndex(CommonDataKinds.Im.PROTOCOL))+",";
    					str+=c.getString(c.getColumnIndex(CommonDataKinds.Im.DATA));
    				}
    				else if(typ.equals(CommonDataKinds.Email.CONTENT_ITEM_TYPE)){
    					str=c.getString(c.getColumnIndex(CommonDataKinds.Email.TYPE))+",";
    					str+=c.getString(c.getColumnIndex(CommonDataKinds.Email.DATA));
    				}
    				else if(typ.equals(CommonDataKinds.Note.CONTENT_ITEM_TYPE)){
    					str=c.getString(c.getColumnIndex(CommonDataKinds.Email.DATA));
    				}
    				else if(typ.equals(CommonDataKinds.Phone.CONTENT_ITEM_TYPE)){
    					str=c.getString(c.getColumnIndex(CommonDataKinds.Phone.TYPE))+",";
    					str+=c.getString(c.getColumnIndex(CommonDataKinds.Phone.DATA));
    				}
    				else if(typ.equals(CommonDataKinds.Photo.CONTENT_ITEM_TYPE)){
    					byte[] buf = c.getBlob(c.getColumnIndex(CommonDataKinds.Photo.PHOTO));
    					str="len is "+buf.length;
    				}
    				else if(typ.equals(CommonDataKinds.Nickname.CONTENT_ITEM_TYPE)){
    					str=c.getString(c.getColumnIndex(CommonDataKinds.Nickname.TYPE))+",";
    					str+=c.getString(c.getColumnIndex(CommonDataKinds.Nickname.DATA));
    				}
    				sb.append("data=id"+j+", t:"+typ+"\n, n:"+str+"\n");
    			}
    			c.close();
    			
    			
    		}
    		
    	}
    	
    	people.close();
    	return sb.toString();
    }
