Hi I want to open a activity when a if statement comes true. like "if gameStatus are equal to 12, then open scoreActivity". The Code:

The activity that i want to open will show to the player his score. the activity is equal to all game modes, there will be some test to the app understant what path should go on. test like this one:
"
if (gameStatus == 12) {
gameScore = gameScore*55;
TextView scoreText = (TextView) findViewById(R.id.textView8);
scoreText.setText(gameScore);
}
else if (gameStatus == 15){
"
There are 4 game modes: This is the 6x4 game, where we can find 24 cards (12 images).
else if (gameStatus == 15){
Intent intent = new Intent(Game6x4Activity.this, NextActivity.class);
startActivity(intent);
}
I think, you are asking for this. You can pass value to another activity with
intent.putExtra("key",desired value);
i wrote a code for calculating some weights. they are integer weights.
and i need to save them in every time the button is clicked.
please help me. i cant see why the compiler gives me an error when i try to push the button for the second time. here is my complete code:
public class TrainingActivity extends Activity {
private EditText etIn1, etIn2, etDesired;
private TextView prevInput;
int W[][] = new int[2][];
int X[][] = new int[30][];
int w0=0, w1=0, w2=0, p=1, sum=0, clicks=0;
private Button nxtData;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.training_activity);
View backgroundImage = findViewById(R.id.background);
Drawable background = backgroundImage.getBackground();
background.setAlpha(40);
etIn1= (EditText) findViewById(R.id.etInput1);
etIn2 = (EditText) findViewById(R.id.etInput2);
etDesired = (EditText) findViewById(R.id.etDesired);
prevInput = (TextView) findViewById(R.id.prevInput);
nxtData = (Button) findViewById(R.id.nextData);
nxtData.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
int sum = 0;
++clicks;
int intetIn1 = Integer.parseInt(etIn1.getText().toString());
int intetIn2 = Integer.parseInt(etIn2.getText().toString());
int intetDesired = Integer.parseInt(etDesired.getText().toString());
X[clicks-1] = new int[] {intetIn1, intetIn2, 1};
prevInput.setText("Last Inputs: (" + intetIn1 + ", " + intetIn2 +
", " + intetDesired + ")");
if(clicks == 1) {
if(intetDesired == 1) {
W[0] = new int[] {intetIn1, intetIn2, 1};
W[1] = W[0];
} else if(intetDesired == (-1)){
W[0] = new int[] {-intetIn1, -intetIn2, -1};
W[1] = W[0];
}
} else if(clicks > 1) {
for(int i=0; i<3; i++){
sum = sum + W[clicks-1][i] * X[clicks-1][i];
} if(sum>0 && intetDesired==1) {
W[clicks] = W[clicks-1];
} else if(sum<0 && intetDesired==(-1)) {
W[clicks] = W[clicks-1];
} else if(sum<=0 && intetDesired==1) {
for(int i=0; i<3; i++) {
W[clicks][i] = W[clicks-1][i] + X[clicks-1][i];
}
} else if(sum>=0 && intetDesired==(-1)) {
for(int i=0; i<3; i++) {
W[clicks][i] = W[clicks-1][i] - X[clicks-1][i];
}
}
}
etIn1.setText("");
etIn2.setText("");
etDesired.setText("");
}
});
}}
and here is the exception it throws:
java.lang.ArrayIndexOutOfBoundsException: length=2; index=2
UPDATEEEEEEEE
i fixed the problem with arrayindexoutofboundexception by changing W[2][] to W[20][]. but in some clicks it gives me this error:
java.lang.NullPointerException
and it's not clear in which clicks. sometimes it's in the second click. or some times it's in fourth click. please help.
W[clicks] = W[clicks - 1];
in above line, you have get error because you have only define size of the array
int W[][] = new int[2][];
so it assigned W[0][] and W[1][] only
When click on second time variable clicks value is 2 then compiler gives ArrayIndexOutOfBoundException
EDITED.............................................................
you have got null value because of your bad logic and not proper way to build two dimensional array. Pls use debug tool to find the actual problem to implement logic and use two dimensional array like below example in java or android:
List<List<Integer>> triangle = new ArrayList<List<Integer>>();
List<Integer> row1 = new ArrayList<Integer>(1);
row1.add(2);
triangle.add(row1);
List<Integer> row2 = new ArrayList<Integer>(2);
row2.add(3);row2.add(4);
triangle.add(row2);
triangle.add(Arrays.asList(6,5,7));
triangle.add(Arrays.asList(4,1,8,3));
System.out.println("Size = "+ triangle.size());
for (int i=0; i<triangle.size();i++)
System.out.println(triangle.get(i));
I am working on a methods in which when I use a single loop with condition it checks both if and else conditions. But when I add more than one loop with condition it only checks else condition I do not know where is problem. please help me for that
here is my code
public void compareArray() {
ArrayList<Boolean> subset = new ArrayList<>();
for (int j = 0; j < (arrayBeef1.length); j++) {
for (int i = 0; i < Items.size(); i++) {
if ((arrayBeef1[j].equals(Items.get(i)))) {
subset.add(true);
break;
}
}
}
if (subset != null) {
if (arrayBeef1.length == subset.size()) {
Intent nextClass = new Intent();
nextClass.setClass(AddItem.this, BeefRecipes.class);
startActivity(nextClass);
finish();
} else {
Toast.makeText(getApplicationContext(), "Un-Matched", Toast.LENGTH_LONG).show();
}
}
for(int j = 0 ; j < (arrayBeef2.length) ; j++) {
for (int i = 0; i < Items.size(); i++) {
if ((arrayBeef2[j].equals(Items.get(i)))) {
subset.add(true);
break;
}
}
}
if (subset != null) {
if (arrayBeef2.length == subset.size()) {
Intent nextClass = new Intent();
nextClass.setClass(AddItem.this, BeefRecipes.class);
startActivity(nextClass);
finish();
} else {
Toast.makeText(getApplicationContext(), "Un-Matched", Toast.LENGTH_LONG).show();
}
}
where Item array is dynamic array which is populated through spinner and beefArray1 and two are
String[] arrayBeef1 = { "carrot","ginger",
"onion","beef","unsalted butter"};
String[] arrayBeef2 = { "garlic","olive oil", "onion",
"Dijon mustard","beef","salt","carrot","rosemary"};
and Items arraList is produced with similar items
please help what should I do with this method

The problem is you cannot addView(view) directly to GridView, because it is an AdapterView which does not allow that. So you have to do this operation in your Adapter. You just have to add more data to the adapter and after call notifyDataSetChanged() on the adapter, so your GridView will be added the View by itself.
I have many buttons(81) from the left and right part of my layout. All in all, I have 162 buttons. I put those buttons to Button[] and I handle it properly.

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
}
