Like that you don't need the Database for take back information.Are you passionate about aviation and electric mobility? Do you want to be part of an innovative startup that is changing the game in the field of electrical design? Look no further than our team! With your intent.putExtra(SELECTED_DEVICE, selecteddevice) you send only the type of device, if you put other information you can take them back from the UpdateDevice and you can SetText() of your EditText with the old data! You can send the old data with the putExtra(). If i understood well, your problem is 'how can i pass to the activity the old data so the user can read them and update?'. I think a simple search within the database to extract all the values that match the device name would work best and then convert the device number attribute to a string and the device password to another string, i just cant work that bit out. looping through all rows and adding to list SQLiteDatabase db = this.getReadableDatabase() Ĭursor cursor = db.rawQuery(selectQuery,null) String selectQuery = 'SELECT * FROM ' + TABLE_NAME

Public class DeviceManager extends Activity implements AdapterView.OnItemSelectedListener Ĭursor = db.query(TABLE_NAME,projections,null,null,null,null,null) Here is my main activity code: package ben.findmyflock I am very new to Java, and I can't figure out how to retrieve the corresponding values from the spinner on the previous page to populate the three different TextView so that the user can update the information. When they select update, they open a new activity with three text views, device name, device number and device password. When the user selects the desired device, they then have the option to update its information or delete it.

On my MainActivity I have a spinner which is populated with data from the 'device_names' table of my SQLite database. I am currently building a small android application.
