Question

I use the below code to fetch a particular record from sqlite.

public String getDetails(long phone) throws SQLException{
    Cursor mCursor = db.query(true, DATABASE_TABLE, new String[] {NAME, AGE, AREA, PHONE, SEX}, PHONE + "=" + phone, null, null, null, null, null);
    if(mCursor != null){
        mCursor.moveToFirst();
    }
    String result = mCursor.getString(mCursor.getColumnIndex(NAME));
    return result;
}

And I am calling this method from another class with the below code

dbAdapterExisting.read();
String temp = dbAdapterExisting.getDetails(mobile);
dbAdapterExisting.close();
textViewExistingName.setText(temp);

The record is getting fetched and am able to display the ‘name’ field in textview, but how do i fetch all the fields i.e ‘age’, ‘area’, ‘sex’ and show it on different textviews.

Since your getDetails() method only returns a single string, and you want to fetch multiple items, you need to change some things. Maps are good data structures for returning data this way. For example:

public Map<String, Object> getDetails(long phone) throws SQLException{

    Map<String, Object> map = new HashMap<String, Object>();

    Cursor mCursor = db.query(true, DATABASE_TABLE, new String[] {NAME, AGE, AREA, PHONE, SEX}, PHONE + "=" + phone, null, null, null, null, null);

    if(mCursor != null){
        mCursor.moveToFirst();
    }

    String name = mCursor.getString(mCursor.getColumnIndex(NAME));
    map.put(NAME, name);
    String age = mCursor.getString(mCursor.getColumnIndex(AGE));
    map.put(AGE, age);
    String area = mCursor.getString(mCursor.getColumnIndex(AREA));
    map.put(AREA, area);
    map.put(PHONE, phone);
    String sex = mCursor.getString(mCursor.getColumnIndex(SEX));
    map.put(SEX, sex);

    return map;

}

Then, in your calling code switch to using the Map returned instead:

Map<String, Object> temp = dbAdapterExisting.getDetails(mobile);
// get the name:
String name = temp.get(dbAdapterExisting.NAME);
// etc..
