I am using custom adapter in my list view that is filterable and I am using two arraylists one is for filterable and second one is for when it come first time in list view. It work properly, and I am using checkbox I want to save the state of the checkbox for that I am using hash map, it work properly but it taking to much time to load the has map array list. What is the best way to keep the checkbox in save state.
below is my code
this is my hashmap and hashmap array list
static HashMap<String, String> map = new HashMap<String, String>();
static ArrayList<HashMap<String, String>> mylist = new ArrayList<HashMap<String, String>>();
in this my string data is coming from SQLite database. It work properly I am using it for checkbox save state.
My data is coming in the string array from sqlite:
text = dbOpenHelper.text;
and after that I am adding the data in list view and filtering it from edit text.
edittext = (EditText) findViewById(R.id.EditText01);
listview = (ListView) findViewById(R.id.ListView01);
listview.setAdapter(new MyCustomAdapter(text, image));
System.out
.println("size of map"+map.size());
System.out
.println("size of list"+mylist.size());
edittext.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {
}
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
public void onTextChanged(CharSequence s, int start, int before,
int count) {
filter_flag = 1;
textlength = edittext.getText().length();
text_sort.clear();
image_sort.clear();
for (int i = 0; i < text.length; i++) {
if (textlength <= text[i].length()) {
if (edittext
.getText()
.toString()
.equalsIgnoreCase(
(String) text[i].subSequence(0,
textlength))) {
text_sort.add(text[i]);
image_sort.add(image[i]);
}
}
}
listview.setAdapter(new MyCustomAdapter(text_sort, image_sort));
}
});
and this is my rest of the code
listview.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> adapter, View v,
int position, long id) {
String str = text[position];
if (filter_flag == 0) {
Toast.makeText(getApplicationContext(),
"text[] = " + text[position], Toast.LENGTH_SHORT)
.show();
Toast.makeText(getApplicationContext(),
"image[] = " + image[position], Toast.LENGTH_SHORT)
.show();
Bitmap bitmap = BitmapFactory.decodeResource(
getResources(), image[position]);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] b = baos.toByteArray();
System.out.println("imagesssss" + b);
Intent intent = new Intent(AllBreeds.this,
BreedDescription.class);
intent.putExtra("picture", b);
startActivity(intent);
// finish();
} else {
Toast.makeText(getApplicationContext(),
"text_sort = " + text_sort.get(position),
Toast.LENGTH_SHORT).show();
Toast.makeText(getApplicationContext(),
"image_sort = " + image_sort.get(position),
Toast.LENGTH_SHORT).show();
Bitmap bitmap = BitmapFactory.decodeResource(
getResources(), image_sort.get(position));

bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] b = baos.toByteArray();
System.out.println("imagesssss" + b);
Intent intent = new Intent(AllBreeds.this,
BreedDescription.class);
intent.putExtra("picture", b);
startActivity(intent);
// finish();
}
}
});
}
