I have 6 object button
kartu1 = (Button)findViewById(R.id.kartu1);
kartu2 = (Button)findViewById(R.id.kartu2);
kartu3 = (Button)findViewById(R.id.kartu3);
kartu4 = (Button)findViewById(R.id.kartu4);
kartu5 = (Button)findViewById(R.id.kartu5);
kartu6 = (Button)findViewById(R.id.kartu6);
All this object set to OnclickListener
kartu1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
r = new Random();
int i = r.nextInt(gamb.size());
v.setBackgroundDrawable(gamb.get(i));
}
});
I want to make all the object as an integer, cause there is a condition to count all the object. I have a condition.
if (kartu1 >= 5){
}
How to change kartu1 to integer?
try this
int[] ids={R.id.kartu1 ,R.id.kartu2, R.id.kartu3, R.id.kartu4, R.id.kartu5,R.id.kartu6 };
int clicks=0;
for(int i=0;i<ids.length;i++)
{
Button b=(Button)findViewById(R.id.kartu1);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
r = new Random();
int i = r.nextInt(gamb.size());
v.setBackgroundDrawable(gamb.get(i));
// set the click count in variable
clicks+=1;
if(clicks>=5){
// do stuff here
}
}
});
}
Second Case.
Above assumes that Total clicks on all images 5
if you want to set individual button click count of 5 do like this
public void onClick(View v) {
r = new Random();
int i = r.nextInt(gamb.size());
v.setBackgroundDrawable(gamb.get(i));
// set the click count in variable
String count=b.getContentDescription();
if(count!=null && count.length()!=0)
{
int cnt=Integer.parseInt(count);
cnt+=1;
button.setContentDescription(String.valueOf(cnt));
if(cnt>=5)
{
// do stuff here
}
}
else
{
button.setContentDescription(String.valueOf(1));
}
}

I want to make button which will call two function on click I am using this code currently but when I click it on 3rd time nothing happens and I want to do vice versa like when user click on button 3rd time it will call count 1 again.. this code is currently I am using
#Override
public void onClick(View v) {
clickcount=clickcount+1;
if(clickcount==1)
{
Random i = new Random ();
int c= i.nextInt(7-1) + 1;
bck.setBackgroundColor(Color.BLACK);
TextView textresult = (TextView) findViewById(R.id.textView);
textresult.setTextColor(Color.WHITE);
}
else
{
Random i = new Random ();
int c= i.nextInt(7-1) + 1;
bck.setBackgroundColor(Color.WHITE);
TextView textresult = (TextView) findViewById(R.id.textView);
textresult.setTextColor(Color.BLACK);
}
}
Hello mate Please do like this
clickcount=0;
#Override
public void onClick(View v) {
clickcount = clickcount + 1;
if(clickcount%2 == 1) {
Random i = new Random ();
int c = i.nextInt(7 - 1) + 1;
bck.setBackgroundColor(Color.BLACK);
TextView textresult = (TextView) findViewById(R.id.textView);
textresult.setTextColor(Color.WHITE);
} else {
Random i = new Random ();
int c = i.nextInt(7 - 1) + 1;
bck.setBackgroundColor(Color.WHITE);
TextView textresult = (TextView) findViewById(R.id.textView);
textresult.setTextColor(Color.BLACK);
}
}
Another solution with boolean:
boolean check = true;
#Override
public void onClick(View v) {
Random i = new Random ();
TextView textresult = (TextView) findViewById(R.id.textView);
int c= i.nextInt(7-1) + 1;
bck.setBackgroundColor(check ? Color.BLACK : Color.WHITE);
textresult.setTextColor(check ? Color.WHITE : Color.BLACK);
check = !check;
}
Or if you want two functions:
boolean check = true;
#Override
public void onClick(View v) {
if(check) {
// first function
} else {
// second function
}
check = !check;
}
I'm trying to get an AlertDialog to appear if my counter is above 10.
I have tried using the TextView variable peopleCount in the if statement but it does not work too. I know using TextView will not work but I need to know if there is a workaround.
private TextView peopleCount;
private ImageView plusOne;
private ImageView minusOne;
private ImageView reset;
private int counter;
private View.OnClickListener clickListener = new View.OnClickListener() {
#Override
public void onClick(View v) {
switch(v.getId()) {
case R.id.ivPlusOne :
plusCounter();
break;
case R.id.ivMinusOne :
minusCounter();
break;
case R.id.ivReset :
initCounter();
break;
}
}
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_people);
peopleCount = (TextView)findViewById(R.id.tvPeopleCount);
plusOne = (ImageView)findViewById(R.id.ivPlusOne);
plusOne.setOnClickListener(clickListener);
minusOne = (ImageView)findViewById(R.id.ivMinusOne);
minusOne.setOnClickListener(clickListener);
reset = (ImageView)findViewById(R.id.ivReset);
reset.setOnClickListener(clickListener);
initCounter();
if( counter > 10) {
AlertDialog.Builder peopleAlert = new AlertDialog.Builder(PeopleActivity.this);
peopleAlert.setCancelable(false);
peopleAlert.setTitle("People Count High");
peopleAlert.setMessage("Please check and replenish inventory");
peopleAlert.setPositiveButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogPeople, int which) {
dialogPeople.cancel();
}
});
peopleAlert.show();
}
private void initCounter(){
counter = 0;
peopleCount.setText(counter + "");
}
private void plusCounter(){
counter++;
peopleCount.setText(counter + "");
}
private void minusCounter(){
counter--;
peopleCount.setText(counter + "");
}
I expected the AlertDialog to appear when counter reached 11 but nothing happens.
OnCreate only runs once, You need to move the if statement to a function and call it from your plusCounter() and minusCounter() functions.
I wish to add the following functionality to my game:
-When the game is complete (no more cards are visible on screen) then move to a new activity
I am aware how to move to another activty using intents but I am not sure how to implement the functionality in this case.
I.e. what variable/info can I use to ensure the game is complete when I move before moving to the next activity?
For reference, The game is based off this open source game Images of the game are shown here to give an idea.

The easiest way to do this would be to check win conditions with an if statement. This should be done in the method when a turn is actually taken which I assume happens in the turnCard() method.
if (winConditionMet) {
displayWinningScreen();
} else if (lossConditionMet) {
displayLosingScreen();
}
If conditions have been met, then call a method which handles wrapping up that screen, and then launching a new activity. For instance you could add a button to the screen with whatever text you wanted, that when pushed, would take the user to the next screen, be it your score screen, replay screen, main menu, or what have you.
Edit: Okay, since this is a game of memory, you could iterate through the cards at the end of every turn taken and check if any card still has its image set to backImage. If there are none left that are set to backImage, you can then end the game with your code inside of the if statement.
Or, instead of using an ArrayList, you could use some form of Map to keep track of if each card has been permanently turned up or not with the boolean value.
How can i change background color of my layout by clicking on a Button ?
This is my code :
Button color_change;
LinearLayout layout;
int value = 1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
color_change = (Button)findViewById(R.id.color_btn);
layout = (LinearLayout)findViewById(R.id.LL);
color_change.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (value == 1) {
layout.setBackgroundColor(Color.RED);
}
else if (value == 2) {
layout.setBackgroundColor(Color.BLUE);
}
else if (value == 3) {
layout.setBackgroundColor(Color.MAGENTA);
}
else if (value == 4) {
layout.setBackgroundColor(Color.DKGRAY);
value = 0;
}
value++;
}
});
But i want replace if else condition with other code , because this code is complex and i want short code.
So any one suggest me, how can i short my code ?
You can try this
put all color into a array and in onclick method get particular color from the array and set it like
int color[]=new int[]{Color.BLUE,Color.RED,Color.GRAY};
color_change.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (value <color.length) {
layout.setBackgroundColor(color[value]);
}
value++;
}
});
There is no magic. Use the switch instead of else ifs. For the added clarity, you might consider having constants or something as values to value, so that you don't have to deal with hard-coded integers.
You could use an array to store the data:
int[] colors = {Color.RED, Color.BLUE, Color.BLACK};
int index = value % colors.length;
layout.setBackgroundColor(colors[index]);
value++;
You will use like this...
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
switch(value)
{
case 1:layout.setBackgroundColor(Color.RED);
break;
case 2:layout.setBackgroundColor(Color.BLUE);
break;
case 3: layout.setBackgroundColor(Color.MAGENTA);
break;
case 4:layout.setBackgroundColor(Color.DKGRAY);
value = 0;
break;
}
value++;
}
});
A list of colors you want to use
List<int> colorsList = new List<int>();
colorsList.add(Color.RED);
colorsList.add(Color.WHITE);
colorsList.add(Color.BLUE);
colorsList.add(Color.GREEN);
//here you can add other colors to list
Iterator<int> colorIterator = colorsList.iterator();
function to get next color
int getNextColor()
{
if(colorIterator.hasNext())
{
return colorIterator.next();
}
else
{
colorIterator = colorsList.iterator();
return colorIterator.next();
}
}
and here is your listener
color_change.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
int color = getNextColor();
layout.setBackgroundColor(color);
}
});
How to change the android button after 2 clicks ?
the first time to change button i will use this code
{
public void onClick(View v) {
b.setBackgroundDrawable(getResources().getDrawable(R.drawable.menubuttonpressed));
}
}
I want to change the button view again after pressing it one more time
how can i do that ?
Perhaps do it like this:
int count = 0;
public void onClick(View v) {
count++;
if(count == 2){
count = 0;
b.setBackgroundDrawable(getResources()
.getDrawable(R.drawable.menubuttonpressed));
}
}
This will set the background after every 2nd click on your button (view).
private int clickCount =0;
public void onClick(View v) {
if (clickCount==0) {
b.setBackgroundDrawable(getResources().getDrawable(R.drawable.menubuttonpressed));
} else {
// do something else
}
clickCount++;
}
Well, one way is to keep a counter.
numberOfClicks = 0;
...
public void onClick(View v) {
...
if(numberOfClicks==0)
b.setBackgroundDrawable(getResources().getDrawable(R.drawable.menubuttonpressed0));
else if(numberofClicks==1)
b.setBackgroundDrawable(getResources().getDrawable(R.drawable.menubuttonpressed1));
...
numberofClicks++;
}
