I am using a SimpleCursorAdapter to populate a ListView. I am retrieving the following two values from a sqlite Database: name and activated. In my Row ListView, I have a ToggleButton named alarm_activated. In the onCreateLoader() Method, I would like to set the setChecked() to true when the value in the Database is 1, otherwise set the setChecked value to false. Furthermore, I would like to change the background color of the ToggleButton in the same onCreateLoader() Method. I have developed the following code for retrieving the values, which is working properly.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mydb = new DBHelper(this);
Cursor cursor = getContentResolver().query(CONTENT_URI, null, null, null, "name, activated");
alarmlv = (ListView)findViewById(R.id.listViewAlarms);
dataAdapter = new SimpleCursorAdapter(getBaseContext(), R.layout.listview_row, cursor,
new String[]{ mydb.ALARMS_COLUMN_NAME, mydb.ALARMS_ACTIVATED }, new int[]{ R.id.alarm_name, R.id.alarm_activated}, 0);
alarmlv.setAdapter(dataAdapter);
getSupportLoaderManager().initLoader(0, null, this);
}
Meanwhile, I am having difficulties referencing the ToggleButtons in the Row View in order to set their properties as described above. Here is my starting code:
public Loader<Cursor> onCreateLoader(int arg0, Bundle arg1) {
alarm_activated = (ToggleButton)row.findViewById(R.id.alarm_activated);
if (activationInt == 1) {
alarm_activated.setChecked(true);
alarm_activated.getBackground().setColorFilter(Color.BLUE, PorterDuff.Mode.MULTIPLY);
} else {
alarm_activated.setChecked(false);
}
alarm_activated.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
buttonView.getBackground().setColorFilter(Color.BLUE, PorterDuff.Mode.MULTIPLY);
} else {
buttonView.getBackground().setColorFilter(Color.LTGRAY, PorterDuff.Mode.MULTIPLY);
}
}
});
return new Loader(this);
}
You should create a custom adapter which extends SimpleCursorAdapter
and use it instead of SimpleCursorAdapter
, then override the getView
method and get the reference of child elements from there.
