I have a CustomAdapter for a listview and I need to save all checkbox states from an array of boolean using SharedPreferences, I would like to save the name of the trick (an Array of String) as the Key and the state for each trick.
Example how SharedPreferences that I have in mind:
("name of the trick", false/true) ("ATW - Around the World", false/true)
Everytime the user change any state it needs to update inside the SharedPreference for the clicked trick.
I tried the two methods below to test but it didn't work, I don't know how to make this work.
storeArray() and loadArray().
listview with the checkboxes
public class CustomAdapter0 extends BaseAdapter {
public CustomAdapter0(String[] tricks, Context context) {
this.tricks = tricks;
this.context = context;
isClicked = new boolean[tricks.length];
for(int i = 0; i < isClicked.length; i++) isClicked[i] = false;
}
private String[] tricks;
private Context context;
private boolean[] isClicked;
private LayoutInflater layoutInflater;
@Override
public int getCount() {
return tricks.length;
}
@Override
public Object getItem(int i) {
return tricks[i];
}
@Override
public long getItemId(int i) {
return i;
}
@Override
public View getView(final int i, View convertView, ViewGroup viewGroup) {
View row = convertView;
if(convertView == null){
layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = layoutInflater.inflate(R.layout.custom_listview_tricks, null);
}
TextView textView = row.findViewById(R.id.name_xml);
ImageButton imageButton = row.findViewById(R.id.unmastered_xml);
textView.setText(tricks[i]);
if (isClicked[i]) imageButton.setBackgroundResource(R.drawable.mastered);
else imageButton.setBackgroundResource(R.drawable.unmastered);
**loadArray**(tricks[i], context);
imageButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
ImageButton clickedView = (ImageButton) view;
int clickedPosition = (int)clickedView.getTag();
isClicked[clickedPosition] = !isClicked[clickedPosition];
notifyDataSetChanged();
**storeArray**(isClicked, tricks, context);
}
});
imageButton.setTag(i);
return row;
}
public boolean **storeArray**(boolean[] array, String[] arrayName, Context mContext) {
SharedPreferences prefs = mContext.getSharedPreferences("preferencename", 0);
SharedPreferences.Editor editor = prefs.edit();
editor.putInt(arrayName +"_size", array.length);
for(int i=0;i<array.length;i++)
editor.putBoolean(arrayName + "_" + i, array[i]);
return editor.commit();
}
public Boolean[] **loadArray**(String arrayName, Context mContext) {
SharedPreferences prefs = mContext.getSharedPreferences("preferencename", 0);
int size = prefs.getInt(arrayName + "_size", 0);
Boolean array[] = new Boolean[size];
for(int i=0;i<size;i++)
array[i] = prefs.getBoolean(arrayName + "_" + i, false);
return array;
}
}
