Android: Loading Fragment is Slow to Get String Values From SQLite

Android: Loading Fragment is Slow to Get String Values From SQLite - android

I try to use SQLite database to get String values and set these values into TextViews in Fragment.The String values are gotten when Boolean variables are returned true, and when loading the fragment, it takes little bit long time to load.
I have tried to use multiple threads to solve the problem but it does not work apparently. Do you have any idea to be faster load the fragment?
This is a class that be called in the fragment
public class Schedule_Config_Monday{
private Context mContext;
public Schedule_Config_Monday(Context context){
this.mContext = context;
}
public void Monday_Schedule_Settings_0(final TextView textView_1,final TextView textView_2,final TextView textView_3,final TextView textView_4,final TextView textView_5,

These are methods inside of a class extends SQLiteOpenHelper to get Title, Text Color and Background Color
public String Monday_Title(int start, int end){
sqLiteDatabase = this.getReadableDatabase();
String[] columns = new String[]{COLUMN_TITLE,COLUMN_SUBTITLE,
COLUMN_MON,COLUMN_START_TIME,COLUMN_END_TIME};
#SuppressLint("Recycle")
Cursor cursor = sqLiteDatabase.query(TABLE_TIMETABLE,columns,COLUMN_MON + "=" + 1 + " AND " + COLUMN_START_TIME + " = " + start + " AND " + COLUMN_END_TIME + " = " + end,null,null,null,null);
int iTitle = cursor.getColumnIndex(COLUMN_TITLE);
int iSubtitle = cursor.getColumnIndex(COLUMN_SUBTITLE);
StringBuilder result = new StringBuilder();
for (cursor.moveToFirst(); !cursor.isAfterLast(); cursor.moveToNext()){
result.append(cursor.getString(iTitle)).append("\n").append("\n").append(cursor.getString(iSubtitle)).append("\n\n");
}
sqLiteDatabase.close();
return result.toString();
}
//Monday Get TextColor
public String Monday_Text_Color(int start, int end){
sqLiteDatabase = this.getReadableDatabase();
String[] columns = new String[]{COLUMN_TITLE,COLUMN_SUBTITLE, COLUMN_COLOR_TEXT,
COLUMN_MON,COLUMN_START_TIME,COLUMN_END_TIME};
#SuppressLint("Recycle")
Cursor cursor = sqLiteDatabase.query(TABLE_TIMETABLE,columns,COLUMN_MON + "=" + 1 + " AND " + COLUMN_START_TIME + " = " + start + " AND " + COLUMN_END_TIME + " = " + end,null,null,null,null);
int iTextColor = cursor.getColumnIndex(COLUMN_COLOR_TEXT);
StringBuilder result = new StringBuilder();
for (cursor.moveToFirst(); !cursor.isAfterLast(); cursor.moveToNext()){
result.append("#").append(cursor.getString(iTextColor));
}
sqLiteDatabase.close();
return result.toString();
}
//Monday Get Text Background Color
public String Monday_Text_BG_Color(int start, int end){
sqLiteDatabase = this.getReadableDatabase();
String[] columns = new String[]{COLUMN_TITLE,COLUMN_SUBTITLE, COLUMN_COLOR_TEXT_BG,
COLUMN_MON,COLUMN_START_TIME,COLUMN_END_TIME};
#SuppressLint("Recycle")
Cursor cursor = sqLiteDatabase.query(TABLE_TIMETABLE,columns,COLUMN_MON + "=" + 1 + " AND " + COLUMN_START_TIME + " = " + start + " AND " + COLUMN_END_TIME + " = " + end,null,null,null,null);
int iTextColor_BG = cursor.getColumnIndex(COLUMN_COLOR_TEXT_BG);
StringBuilder result = new StringBuilder();
for (cursor.moveToFirst(); !cursor.isAfterLast(); cursor.moveToNext()){
result.append("#").append(cursor.getString(iTextColor_BG));
}
sqLiteDatabase.close();
return result.toString();
}
This is a method that returns true if defined start and end are in the database
public Boolean Monday_Start_End_Time(int start, int end){
sqLiteDatabase = this.getReadableDatabase();
String[] columns = new String[]{COLUMN_MON,COLUMN_START_TIME,COLUMN_END_TIME};
#SuppressLint("Recycle")
Cursor cursor = sqLiteDatabase.query(TABLE_TIMETABLE,columns,COLUMN_MON + "=" + 1 + " AND " + COLUMN_START_TIME + " = " + start + " AND " + COLUMN_END_TIME + " = " + end,null,null,null,null);
boolean result = cursor.moveToFirst();
cursor.close();
sqLiteDatabase.close();
return result;
}
I am currently thinking what makes slow loading fragment is this Boolean check, so that I tried to create a function that returns integer value when the boolean variables are true, but it also slow to load the fragment.
And I am sure the problem is method of public void Monday_Schedule_Settings_0 because when I remove the code, the fragment loads definitely faster.
I would love to hear you advise.

I think your performance problem is that you're closing the database and reopening it with every DB query. You should be closing the cursors, but not closing the database itself. IE you should remove every instance of:
sqliteDatabase.close();

Recursive(Tower Hanoi) UI for android

I want to implement UI through recursive function. When you run it, you should see the process of changing the UI according to the value, but if you insert hanoi(), the process does not come out and the value is printed at once. I think I need to change the move, but it's the same if I put sleep() in the move, and I tried Thread, Handler, AsyncTask, but the results are the same. I'd appreciate your help.

I got error in tis line :

But I added element in "kelimebol" array in this code :

How I can resolve this problem - error?
I wait your help and answers.
Note : I doesn't had a good English. I hope you can understand me. Pardon me.

type missmatch : cannot convert from string to int

public void clickresult(View v){
String temp = "";
int cards[] = {etnumber1.getText().toString(),etnumber2.getText().toString(),
etnumber3.getText().toString(),etnumber4.getText().toString()
,etnumber4.getText().toString()};
int noOfCard = cards.length;
for (int marker = 1; marker < noOfCard; marker++) {
for (int j = 0; j < marker; j++) {
if (cards[marker] < cards[j]) {
int tmp = cards[marker];
cards[marker] = cards[j];
cards[j] = tmp;
}
}
}
for (int i = 0; i < noOfCard; i++) {
temp += cards[i] + " ";
}
Toast.makeText(this, temp, Toast.LENGTH_LONG).show();
}
it still have one error -> type missmatch : cannot convert from string to int
how to fix that
int cards[] = {etnumber1.getText().toString(),etnumber2.getText().toString(),
etnumber3.getText().toString(),etnumber4.getText().toString()
,etnumber4.getText().toString()};

#Override
protected void onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.your_fragment_layout, container, false);
etnumber1 = (EditText)findViewById(R.id.etnumber1);
etnumber2 = (EditText)findViewById(R.id.etnumber2);
etnumber3 = (EditText)findViewById(R.id.etnumber3);
etnumber4 = (EditText)findViewById(R.id.etnumber4);
etnumber5 = (EditText)findViewById(R.id.etnumber5);
}
public void onClickResult(){
String cards[] = {etnumber1.getText().toString,
etnumber2.getText().toString(),
etnumber3.getText().toString(),
etnumber4.getText().toString(),
etnumber5.getText().toString()
};
int noOfCard = cards.length;
Arrays.sort(cards);
StringBuilder builder = new StringBuilder();
for (String s : cards)
builder.append(s).append(" ");
Toast.makeText(context, builder.toString(), Toast.LENGTH_SHORT).show();
}
This will sort your array and display it in a Toast in this format: "2 3 5 6 7" (according to the numbers you provided). If the EditTexts are going to have only numbers, consider using NumberPicker instead.
LENGTH_SHORT can also be LENGTH_LONG.

Whenever I click on the button, just like in mine sweeper game, many buttons are randomly opened. And when it is opened, I am changing its background into R.drawable.affected. The goal of the game is to open all the buttons in left and right. My question is this, how can I check if all of the buttons are set in R.drawable.affected? Because after that, I will execute a method that will congratulate the user. Thanks in advance.
EDIT:
for (int i = 0; i < btn_right.length; i++) {
final int a = i;
int counter_total_affected = 0;
btn_right[i].setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (counter == 1) {
right_lung.add(a);
btn_right[a].setBackgroundResource(R.drawable.affected);
counter_total_affected++;
} else if (counter == 2) {
for (int i = 0; i < 2; i++) {
int n = i;
right_lung.add(a + n);
}
try {
for (int i = 0; i < 2; i++) {
int n = i;
btn_right[a + n].setBackgroundResource(R.drawable.affected);
counter_total_affected++;
}
} catch (Exception e) {
e.printStackTrace();
}
} else if (counter == 3) {
right_lung.add(a);
btn_right[a].setBackgroundResource(R.drawable.affected);
counter_total_affected++;
} else if (counter == 4) {
for (int i = 0; i < 25; i++) {
int n = i;
right_lung.add(a + n);
}
try {
for (int i = 0; i < 25; i++) {
int n = i;
btn_right[a + n].setBackgroundResource(R.drawable.affected);
counter_total_affected++;
}
} catch (Exception e) {
e.printStackTrace();
}
} else if (counter == ...) {
//statements...
} else if (counter_total_affected == (btn_left.length + btn_right.length)) {
//CONGRATULATORY METHOD
}
counter++;
}
}

Increment the counter each time you change background of button and compare its value with length of button array. if both are same that means, all button backgrounds are set.
Try this :
for (int i = 0; i < btn_right.length; i++) {
final int b = i;
btn_right[i].setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if btn_right[i].getDrawable().getConstantState().equals
(getResources().getDrawable(R.drawable.affected).getConstantState()))
{
if(counter == btn_right.length){
//Congratulate user...
}
}else{
btn_right[b].setBackgroundResource(R.drawable.affected);
counter++;
}
}
}

U can set Tag:
for (int i = 0; i < btn_right.length; i++) {
final int b = i;
btn_right[i].setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (counter == 1) {
right_affected.add(b);
btn_right[b].setBackgroundResource(R.drawable.affected);
btn_right[b].setTag('1');
} else {
//some stuff here...
}
}
}
after congratulate the user set its Tag to 0.
EDIT:
ArrayList<Integer> arrayofId =new ArrayList<Integer>();
#Override
public void onClick(View v) {
if (counter == 1) {
right_affected.add(b);
btn_right[b].setBackgroundResource(R.drawable.affected);
arrayofId.add(b);//need to convert int to Integer.
} else {
//some stuff here...
}
}
To congratulate:
for(int i=0;i<arrayofId.size();i++)
{
// you can get here id of effected buttons

this all of my code.

You don't show where you create your handler (onCreate ? onStart ? somewhere else ?). Is it started from the main thread ? If so, you need to be provide a more complete stack trace so we can understand.
If you're starting it from another thread then that's the issue because it's attempting to change progressDialog and that must be done from the main thread.
PS: if you used an AsyncTask you wouldn't have to scratch your head around this as it's designed to do exactly what you want and be thread safe.
Post comment : use an AsyncThread : add the progress bar in onPreExecute(), change run() to doInBackground() and move the dismiss() to onPostExecute(

Android: Loading Fragment is Slow to Get String Values From SQLite - android

I think your performance problem is that you're closing the database and reopening it with every DB query. You should be closing the cursors, but not closing the database itself. IE you should remove every instance of: sqliteDatabase.close();
