How to retrive data of pojo initialized class?

Question

What i already done?

I want to get a call history in a array and want to pass that array to MySQL database so i have created pojo class and set that variable in getter and setter method. here's my java code for pojo class..

public class DataBean {
    String number;
    String type;
    String date;
    String duration;

    public DataBean(String number, String type, String date, String duration) {
        this.number = number;
        this.type = type;
        this.date = date;
        this.duration = duration;
    }

    public String getNumber() {
        return number;
    }

    public void setNumber(String number) {
        this.number = number;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public String getDate() {
        return date;
    }

    public void setDate(String date) {
        this.date = date;
    }

    public String getDuration() {
        return duration;
    }

    public void setDuration(String duration) {
        this.duration = duration;
    }
}

from this pojo class i want set call detail into that initialized variable. here's my java code for MainActivity.and from this code i am making every time a new instance of databean so i'm getting each time a new arraylist but i want just one array of whole data..

public class MainActivity extends AppCompatActivity {

ListView listView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    listView = (ListView) findViewById(R.id.list);
    getCallDetails();
}

public void getCallDetails() {

    String strOrder = android.provider.CallLog.Calls.DATE + " DESC";

    Cursor managedCursor = managedQuery(CallLog.Calls.CONTENT_URI, null, null, null, strOrder);
    int number1 = managedCursor.getColumnIndex(CallLog.Calls.NUMBER);
    int type1 = managedCursor.getColumnIndex(CallLog.Calls.TYPE);
    int duration1 = managedCursor.getColumnIndex(CallLog.Calls.DURATION);


    while (managedCursor.moveToNext()) {

        String number = managedCursor.getString(number1);
        String type2 = managedCursor.getString(type1);
        String date11 = managedCursor.getString(managedCursor.getColumnIndexOrThrow("date")).toString();
        java.util.Date date1 = new java.util.Date(Long.valueOf(date11));
        String duration = managedCursor.getString(duration1);
        String type = null;

        String date = date1.toString();

        int callcode = Integer.parseInt(type2);
        switch (callcode) {
            case CallLog.Calls.OUTGOING_TYPE:
                type = "Outgoing";
                break;
            case CallLog.Calls.INCOMING_TYPE:
                type = "Incoming";
                break;
            case CallLog.Calls.MISSED_TYPE:
                type = "Missed";
                break;

        }
        DataBean dataBean = new DataBean(number, type, date, duration);
        ArrayList<DataBean> arrayList = new ArrayList<>();

        arrayList.add(dataBean);
        Log.d("tag", arrayList.toString());

    }
    managedCursor.close();


    /*//ArrayAdapter adapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, arrayList);
    listView.setAdapter(adapter);*/

}

}

from this i can get number, duration ,date and call type in a logcat.

What i want?

i want to add that in a arraylist of databean don't why but every time databean shows following text..

12-02 15:18:50.636 8034-8034/com.example.hiren.callhistory D/Arrat: [com.example.hiren.callhistory.DataBean@46540ec]

i'm not getting arraylist value and i want insert that array into mysql table.

Answer 1

Here you have a while loop to read a cursor.

while (managedCursor.moveToNext()) {

In there, you want to generate your Bean an insert those in a list.

For now, you only save the value in ONE instance. You should build a new instance each time :

while (managedCursor.moveToNext()) {
    dataBean = new DataBean(...);
}

but for that, you need the value, so save the values of the cursor into the variable you have, not in the instance. And of course. Add the instance in the list after it is instanciate

ArrayList<DataBean> list = new ArraysList<>();
while (managedCursor.moveToNext()) {
    number = managedCursor.getString("number");
    type = managedCursor.getString("type");
    ...
    dataBean = new DataBean(number, type, date, duration);
    list.add(dataBean);
}
Log.d("tag", arrayList.toString());
