use shuffelArray as global variable

We are trying to use this array of integers in other methods. Setting the final shuffled Array to a global variable has become next to impossible. We have set other variable as global. The goal here is to have a new int [] fix array every time a button is clicked. We have been able to generate a random int [] ar but can not utilize the array in other methods. So our questions after making the random int [] ar how can we use it in the onClickBtnOne method? Code with comments below
public class MainActivity extends AppCompatActivity {
Button btn1,btn2,btn3,btn4,btn5,btn6;
String T1,T2,T3,T4,T5,T6;
int test[] = new int[7];
int count = 0;
int v1,v2,v3,v4,v5,v6;
int[] fix = {3,2,1,4,6,5};
// Trying to not use above values
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn1 = findViewById(R.id.btn1);
btn2 = findViewById(R.id.btn2);
btn3 = findViewById(R.id.btn3);
btn4 = findViewById(R.id.btn4);
btn5 = findViewById(R.id.btn5);
btn6 = findViewById(R.id.btn6);
main(null);
}
// end onCeate
public static void main(String args[]) {
int [] fix = {1,2,3,4,5,6};
shuffleArray(fix);
// Want to USE this fix shuffleArray
//==================================
for (int i = 0; i < fix.length; i++) {
System.out.print(fix[i] + ",");
}
System.out.println();
}
// Implementing Fisher–Yates shuffle
static void shuffleArray(int [] ar) {
// If running on Java 6 or older, use `new Random()` on RHS here
Random rnd = ThreadLocalRandom.current();
for (int i = ar.length - 1; i > 0; i--) {
int index = rnd.nextInt(i + 1);
// Simple swap
int a = ar[index];
ar[index] = ar[i];
ar[i] = a;
}
}
public void onClickBtnOne(View view){
btn1.setBackgroundColor(getColor(R.color.color_Red));
btn1.setEnabled(false);
count = count + 1;
v1 = count;
test[v1] = count;
if(fix[0] == test[v1]){
// Need a global fix[] here
// =========================
T1 = "true";
if(T1.matches("true")){
btn1.setBackgroundColor(getColor(R.color.color_Yellow));
}
}else {
T1 = "false";
}
}

The array you are trying to use does not have an add method you need to put the values in from another variable like this ar[i] = a; So if you use this type of Array declaration List value = new ArrayList<>(); where you declared the other global variable life will be much easier. Modified code below
This will do the shuffle NOTICE value.clear() without this the List will grow each time it is initialized
public void shf(View view){
value.clear();
for (int i = 1; i <= 6; i++) {
value.add(i);
}
Collections.shuffle(value);
}
And here is your test method call value.get(index) Arrays are ZERO based
public void on1(View view){
btn1.setBackgroundColor(getColor(R.color.color_Red));
btn1.setEnabled(false);
if(value.get(0) == 1){
T1 = "true";
if(T1.matches("true")){
btn1.setBackgroundColor(getColor(R.color.color_Yellow));
}
}else {
T1 = "false";
}
}

Android Bookmak Page by Clicking Image not working

I wrote the core to add PDF pages to shared-preference for bookmarks, but when I click the image neither the image get changed nor the page number added to the book mark list.
Below is my code. It show me no error and image get clicked but the page number not added to spinner for book mark list.
Before I used a textview for the task and that was working fine but now I want a tag image to get changed when I tag or un-tag a page.

I resolved my issue by adding a drawable resource
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:drawable="#drawable/tagged" />
<item android:state_checked="false" android:drawable="#drawable/untaged" />
</selector>
and made below changes in my java activity code.
if (((CheckBox) findViewById(R.id.chk_tag)).isChecked()) {
sharedpreferences.edit().putString(KEY_BOOKMARKS, sharedpreferences.getString(KEY_BOOKMARKS, "") + pageNumber + ",").commit();
((CheckBox) findViewById(R.id.chk_tag)).setChecked(true);
dataAdapter.add(pdfView.getPageCount() - (pageNumber - 1) + "");
dataAdapter.notifyDataSetChanged();
} else {
sharedpreferences.edit().putString(KEY_BOOKMARKS, sharedpreferences.getString(KEY_BOOKMARKS, "").replace(pageNumber + ",", "")).commit();
((CheckBox) findViewById(R.id.chk_tag)).setChecked(false);
}

Spinner Value is not preserved for 2nd spinner onStart

I have two spinners, the information on the 2nd spinner is based on the 1st spinner selection
EXAMPLE
SPINNER 1 PROTEIN DAIRY FRUITS
IF SPINNER 1 IS SET WITH PROTEIN then SPINNER 2 EGG CHICKEN
IF SPINNER 1 IS SET WITH FRUITS then SPINNER 2 APPLE ORANGE
Last value selected SPINNER 2 ORANGE
Now I want to preserve the last values selected of the SPINNER1 and SPINNER2, I am using SharedPreferences to accomplish this, it works as expected for SPINNER 1 FRUITS
Position 2 however for SPINNER2 it does not set the last value selected even though the position is correct position 1 when it is called onStart(); it selects the 1st value that is on the array APPLE
Any help would be appreciated
Thanks

//---------------------------------------HERE IS THE PROBLEM SETTING THE CORRECT VALUE FOR SPINNER --------------------

Resources res = getResources();
oilsFoodInformation = res.getStringArray(R.array.SpinnerArrayInfoOils);
if (spinnerFoodCategoryRow1.getSelectedItemPosition() == positionRow1) {
tToast("OILS TYPE TRUE");
int positionRow1Oils = sharedPrefGetInfo.getInt("ROW1-OILS", 0);
//THIS IS THE CORRECT POSITION FOR SPINNER 2

if (positionRow1Oils >= 0) {

res.getStringArray(R.array.SpinnerArrayInfoOils));
spinnerFoodNameRow1.setAdapter(spinnerFoodNameRow1Adapter);
tToast("Iteration # = " + n);
// LOAD SPINNER INFORMATION ROW1 OILS
if (n == positionRow1Oils) {
tToast("SPINNER FOOD NAME IS SET");
spinnerFoodNameRow1.setSelection(positionRow1Oils); // NOT
// WORKING
}
}
} // end if
}
// -----------------------------------------------------------------------------------------------------------------------
currentDateString = DateFormat.getDateInstance().format(new Date());
keyRow1 = currentDateString + "-" + "keyRow1";
getBackInformationRow1 = sharedPrefGetInfo.getString(keyRow1, "");
// MAKE SURE THE ARRAY KEY IS NOT EMPTY
if (!getBackInformationRow1.equals("")) {
getBackInformationParseRow1 = getBackInformationRow1.split(" - ", 4);
textViewProteinRow1.setText(getBackInformationParseRow1[0]);
textViewCarbsRow1.setText(getBackInformationParseRow1[1]);
textViewFatRow1.setText(getBackInformationParseRow1[2]);
textViewCaloriesRow1.setText(getBackInformationParseRow1[3]);
}
}// end class

To fix my problem I just got the info stored (sharedPref) on onStart(); and set the spinner using the position (positionRow1Oils) gotten from it, on the method selection for spinner1 spinnerFoodNameRow1.setSelection(positionRow1Oils);
public void onStart() {
super.onStart();
positionRow1Oils = sharedPrefGetInfo.getInt("ROW1-OILS", 0);
}
public String getSelectedFoodCategoryRow1() {
Resources res = getResources();
String selectedspinnerFoodCategoryRow1 = (String) spinnerFoodCategoryRow1.getSelectedItem();
sharedPrefStoreInfo = PreferenceManager.getDefaultSharedPreferences(this);
//FOOD NAME OILS ROW1
if (spinnerFoodCategoryRow1.getSelectedItemPosition() == 0)
{
//POPULATE INFORMATION FROM STRINGS XML TO FOOD NAME SPINNERS DEPENDING ON INFORMATION ON SELECTED ON FOOD CATEGORY SPINNER ROW1
spinnerFoodNameRow1Adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, res.getStringArray(R.array.SpinnerArrayInfoOils));
spinnerFoodNameRow1.setAdapter(spinnerFoodNameRow1Adapter);
//PRESERVE SPINNER INFORMATION ROW1
int selectedPosition = spinnerFoodCategoryRow1.getSelectedItemPosition();
SharedPreferences.Editor editor = sharedPrefStoreInfo.edit();
editor.putInt("ROW1", selectedPosition);
editor.commit();
*//SET SPINNER FOODNAME OILS WITH THE INFORMATION (POSITION) GOT FROM SHARERE PREFERENCE*
spinnerFoodNameRow1.setSelection(positionRow1Oils);
return selectedspinnerFoodCategoryRow1;
}
It seems that, when a spinner2 information is set based in spinner1 information, to preserve the information from spinner2 it should be set in spinner1 method and not on the onStart();
It hope it helps someone facing the same issue.

Using AlertDialog.Builder to build custom AlertDialog class

I have a Class FoodDialog that extends AlertDialog that I have customized to how I would like it to look.
I am now wanting to edit the positive/negative buttons using an AlertDialog.Builder, however, when I attempt to build an instance of FoodDialog using a builder, I am facing an 'Incompatible types' error where the builder is asking for AlertDialog instead I am providing it with an extension of AlertDialog - is there a way around this?
If not, is there a way I can edit the positive/negative buttons of my custom AlertDialog class FoodDialog?
Below is my FoodDialog class. The yes/no buttons I have there are ones I have created myself, but I would like the ones that are part of the AlertDialog.Builder to appear instead as these buttons get pushed out of sight when the soft keyboard appears:

You can catch your buttons click listener as follows:
yesBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//yes button click code here
}
});
noBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//no button click code here
}
});
You can use the logcat to see if your listener are being fired.

Add Numbers from TextView Android

I need to pick a button, 'H' which represents the atomic element in periodic table, as many times as needed, and it has to add up the overall weight number, and display it in the mw_results.
So far, I am only able to display it, for two times, as I had hard coded it the value.
Any ideas how I could keep adding the number, without hard coding it..?
Thanks.!
Below is the code:
public void Chem()
{
final Dialog g = new Dialog(Sol.this);
g.setContentView(R.layout.table);
final float[] MoWeight = {0};
mw_result = (TextView)findViewById(R.id.editText);
mf_result = (EditText)findViewById(R.id.editText4);
Chemname = "";
final String space = " ";
final int number = 0;
Button H = (Button) g.findViewById(R.id.H);
Button C = (Button) g.findViewById(R.id.C);
H.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
switch (v.getId()) {
case R.id.H:
mf_result.append(String.valueOf("H"));
mw_result.setText(String.valueOf(123));
float MoWeight = Float.valueOf(mw_result.getText().toString());
MoWeight = Float.valueOf(mw_result.getText().toString()) + MoWeight;
String mw_res=Float.toString(MoWeight);
mw_result.setText(mw_res);
mw_result = (TextView)findViewById(R.id.editText);
g.dismiss();
}
}
});
C.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
switch (v.getId()) {
case R.id.C:
mf_result.append(String.valueOf("C"));
mw_result.setText(String.valueOf(456));
float MoWeight = Float.valueOf(mw_result.getText().toString());
MoWeight = Float.valueOf(mw_result.getText().toString()) + MoWeight;
String mw_res=Float.toString(MoWeight);
mw_result.setText(mw_res);
mw_result = (TextView)findViewById(R.id.editText);
g.dismiss();
}
}
});
g.show();
}

It seems like you're resetting the text view back to 123 and 456 respectively on each click.
It's kinda hard to see exactly what you want, but this might help you to get on the right track:
public void Chem()
{
final Dialog g = new Dialog(Sol.this);
g.setContentView(R.layout.table);
final float[] MoWeightArray = {0}; //rename this for readability -- is this used at all?
mw_result = (TextView)findViewById(R.id.editText);
mf_result = (EditText)findViewById(R.id.editText4);
Chemname = "";
final String space = " ";
final int number = 0;
Button H = (Button) g.findViewById(R.id.H);
Button C = (Button) g.findViewById(R.id.C);
H.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
switch (v.getId()) {
case R.id.H:
String sMW= mw_result.getText().toString();
mf_result.append(String.valueOf("H"));
if (sMW.matches("")) {
mw_result.setText(String.valueOf(123));
}
else{
float MoWeight = Float.valueOf(sMW);
MoWeight += 123;
String mw_res=Float.toString(MoWeight);
mw_result.setText(mw_res);
//mw_result = (TextView)findViewById(R.id.editText); no need for this
g.dismiss();
}
}
}
});
C.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
switch (v.getId()) {
case R.id.C:
String sMW= mw_result.getText().toString();
mf_result.append(String.valueOf("C"));
if (sMW.matches("")) {
mw_result.setText(String.valueOf(456));
}
else{
float MoWeight = Float.valueOf(sMW);
MoWeight += 456;
String mw_res=Float.toString(MoWeight);
mw_result.setText(mw_res);
//mw_result = (TextView)findViewById(R.id.editText); No need for this
g.dismiss();
}
}
}
});
g.show();
}

Try this:
public void Chem()
{
final Dialog g = new Dialog(Sol.this);
g.setContentView(R.layout.table);
final float[] MoWeight = {0};
mw_result = (TextView)findViewById(R.id.editText);
mf_result = (EditText)findViewById(R.id.editText4);
Chemname = "";
final String space = " ";
final int number = 0;
Button H = (Button) g.findViewById(R.id.H);
Button C = (Button) g.findViewById(R.id.C);
mw_result.setTag(1);//1 in case you're updating 123 values
mw_result.setTag(2);//2 in case you're updating 456 values
H.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
int key = Integer.parseInt(mw_result.getTag().toString());
if(key==2){
mw_result.setTag(1);//1 in case you're updating 123 values
mf_result.append(String.valueOf("H"));
mw_result.setText(String.valueOf(123));
g.dismiss();
}
else{
float MoWeight = Float.valueOf(mw_result.getText().toString());
MoWeight = Float.valueOf(mw_result.getText().toString()) + 1;
String mw_res=Float.toString(MoWeight);
mw_result.setText(mw_res);
}
}
});
C.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
int key = Integer.parseInt(mw_result.getTag().toString());
if(key==1){
mw_result.setTag(2);//1 in case you're updating 123 values
mf_result.append(String.valueOf("C"));
mw_result.setText(String.valueOf(456));
g.dismiss();
}
else{
float MoWeight = Float.valueOf(mw_result.getText().toString());
MoWeight = Float.valueOf(mw_result.getText().toString()) + 1;
String mw_res=Float.toString(MoWeight);
mw_result.setText(mw_res);
}
}
});
g.show();
}
