Question

I am new to android. I want to show inserted data from database to a table. I have used List to get the data.

 public List<user> getAllUsers() {
    List<user> users = new ArrayList<user>();

    Cursor cursor = database.query(SqlLiteHelper.TABLE_USER, allColumns, null, null, null, null, null);

    cursor.moveToFirst();
    while (!cursor.isAfterLast()) {
      user varUser = cursorToUser(cursor);

      //Log.v("user name",varUser.getName().toString());

      users.add(varUser);
      cursor.moveToNext();
    }
    //Log.v("user name",users.get(0).getName().toString());

    cursor.close();
    return users;
  }



   private user cursorToUser(Cursor cursor) {
    user varUser = new user();

    //Log.v("user id", cursor.getString(1).toString());

    varUser.setID(cursor.getLong(0));
    varUser.setName(cursor.getString(1));
    varUser.setPhone(cursor.getString(2));
    varUser.setEmail(cursor.getString(3));
    return varUser;
}

I wrote this code on UserDataSource.java

Then where i need to show those data i use the following codes

       databaseSource = new UserDataSource(this);
    databaseSource.open();

    List<user> values = databaseSource.getAllUsers();
    Log.v("information", values.get(0).getName().toString());
    ArrayAdapter<user> adapter = new ArrayAdapter<user>(this, android.R.layout.simple_list_item_1, values);
    setListAdapter(adapter);  

This is not adding the values in the list. I use the log.v to check whether the data is coming back or not. And i found that the data is coming perfectly from the database. Only when i try to print the List or insert it to the simple_list_item_1 then it is doing the problem.

It is printing

com.example.given_n_take.user@41221338

Buts its suppose to print the name from the database.

Database table name is user.

Please let me know what am i missing.

here is my xml file of layout where i am trying to add those list

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >


<Button
    android:id="@+id/all_user_back"
    style="?android:attr/buttonStyleSmall"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="10dp"
    android:text="Back" />



    <ListView
    android:id="@android:id/list"
    android:layout_width="match_parent"
    android:layout_height="384dp" >
</ListView>




</LinearLayout>

Answer 1

If your list shows com.example.given_n_take.user@41221338 this means that you are missing a toString method in your user class. Implement a toString that returns the name of the user.
