Is there any libraries are available to convert Cursor object to direct XML or JSON .
For example , we have a table with two columns id,name. When i get cursor object from DB. With out looping cursor i want to convert it into
<XML>
<id>1<id>
<name>xyz</name>
</XML>
Thanks in advance.
Use this:
JSONArray array = new JSONArray();
if (cursor != null && cursor.getCount() > 0) {
while (cursor.moveToNext()) {
JSONObject object = new JSONObject();
try {
object.put("id", cursor.getString(0));
object.put("name", cursor.getString(1));
array.put(object);
} catch (JSONException e) {
e.printStackTrace();
}
}
And if you want to create a XML data than use this: Link. Hope it will help you.
Let us say that I have table named "persons" with some data
id | name | lastname
1 | john | Doe
2 | jane | Smith
and this is my simple code:
public String getRecords(String selectQuery){
String recordSet = null;
Cursor mCursor = database.rawQuery(selectQuery, null);
String[] colName = mCursor.getColumnNames();
if (mCursor != null) {
recordSet = "{";
mCursor.moveToFirst();
do{
StringBuilder sb = new StringBuilder();
int columnsQty = mCursor.getColumnCount();
for(int idx=0; idx<columnsQty; ++idx){
sb.append(mCursor.getString(idx));
if(idx<columnsQty-1){
sb.append(";");
}
}
if(mCursor.getPosition()>0){
recordSet +=",";
}
String row = formatRecords(colName, sb.toString());
recordSet+= "\""+mCursor.getPosition()+"\":["+row+"]";
}while(mCursor.moveToNext());
recordSet += "}";
return recordSet;
}
}
public String formatRecords(String[] colname, String rowData){
String formatedData = null;
String[] data = rowData.split(";");
int colCount = colname.length;
if(rowData !=null){
formatedData = "{";
for(int col=0; col<colCount; col++){
if(col>0){
formatedData += ", ";
}
formatedData += "\""+colname[col]+"\":\""+data[col]+"\"";
}
formatedData += "}";
}
Log.i(tag, formatedData);
return formatedData
Then I will use it as
String data = getRecords("SELECT * FROM persons");
the return will like:
{"0":[{"id":"1","name":"john","lastname":"Doe"}],"1":[{"id":"2","name":"jane","lastname":"Smith"}]}
Anyway I made the return type as String for general purpose. :) Thanks.
