Question

I have a problem with an example I come up googling for android sqlite program, here is a source:

appTest.java

import android.app.Activity;
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import android.os.Bundle;
import android.widget.TextView;

public class appTest extends Activity {
    private static String[] FROM = { "ID", "TIME", "TITLE", };
    private static String ORDER_BY = "TIME DESC";

    private EventsData events;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        events = new EventsData(this);
        try {
            addEvent("Hello, Android!");
            Cursor cursor = getEvents();
            showEvents(cursor);
        } finally {
            events.close();
        }
    }

    private void addEvent(String string) {
        SQLiteDatabase db = events.getWritableDatabase();
        ContentValues values = new ContentValues();
        values.put("titme", System.currentTimeMillis());
        values.put("title", string);
        db.insertOrThrow("event", null, values);
    }

    private Cursor getEvents() {
        SQLiteDatabase db = events.getReadableDatabase();
        Cursor cursor = db.query("event", FROM, null, null, null, null,ORDER_BY);
        startManagingCursor(cursor);
        return cursor;
    }

    private void showEvents(Cursor cursor) {
        StringBuilder builder = new StringBuilder("Saved events:\n");
        while (cursor.moveToNext()) {
            long id = cursor.getLong(0);
            long time = cursor.getLong(1);
            String title = cursor.getString(2);
            builder.append(id).append(": ");
            builder.append(time).append(": ");
            builder.append(title).append("\n");
        }
        // Display on the screen
        TextView text = (TextView) findViewById(R.id.empty);
        text.setText(builder);
    } 
}

class EventsData extends SQLiteOpenHelper {
    private static final String DATABASE_NAME = "events.db";
    private static final int DATABASE_VERSION = 1;

    /** Create a helper object for the Events database */
    public EventsData(Context ctx) {
        super(ctx, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        db.execSQL("CREATE TABLE event (id INTEGER PRIMARY KEY AUTOINCREMENT, time INTEGER,title TEXT NOT NULL);");
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        db.execSQL("DROP TABLE IF EXISTS event");
        onCreate(db);
    }
}

main.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <!-- Note built-in ids for 'list' and 'empty' -->
    <ListView
        android:id="@+id/list"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>
    <TextView
        android:id="@+id/empty"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/empty" />
</LinearLayout>

string.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="app_name">Events</string>
    <string name="empty">No events!</string>
</resources>

the error I receive is……:

java.lang.runtimeexception: unable to start activity componentInfo(test.o/test.o.appTest): android.database.sqlite.SQLiteException: table event has no column named titme: while compiling: insert into event (title, titme) values (?,?);

any ideas?

ok I found this “titme” :), now I have blank screen [ with title of an app ]

Answer 1

change values.put("titme", System.currentTimeMillis()); to values.put("time", System.currentTimeMillis());
