I am trying to create a word game, where all the letters in a word will be added to a grid layout and presented to the user. The user then has to form the word by clicking the letter buttons. The buttons will be disabled once pressed. If the user decides to reset the game, the same grid layout has to be presented again to the user with all the buttons enabled. Is there any function that can be used to set all the buttons as Clickable? Below is the code, I used.
for(final String letter : shuffled_word){
final Button button = new Button(this);
button.setText(letter);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
button.setClickable(false);
}
});
this.game_grid.addView(button);
}
int id = getResources().getIdentifier("button"+i, "id", getActivity().getPackageName());
Button b=(Button) view.findViewById(id);
and then b.setClickable(falsE)

I am creating a word game application , I have created a grid view consisting of buttons. When I click a button in the grid view a popup windows opens which contains all the English alphabets.Now when I click any letter in my pop up window , I want that letter to appear in my grid that is the string in my pop window's button must appear in my grid view's button. , how do I do it?
This is my button's code:
button1.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v) {
layoutInflater = (LayoutInflater) getApplicationContext().getSystemService(LAYOUT_INFLATER_SERVICE);
View container = layoutInflater.inflate(R.layout.activity_popup,null);
popupWindow = new PopupWindow(container,800,1100,true);
popupWindow.showAtLocation(constraintLayout, Gravity.NO_GRAVITY,150,400);
b1=(Button) findViewById(R.id.b1);
String s1 = b1.getText().toString();
button1.setText(s1);
container.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View view, MotionEvent motionevent){
popupWindow.dismiss();
return true;
}
});
}
});
My popup window's code:
b1.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
String s1 = "A";
overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
finish();
}
});
Screenshots of the app
This is my grid layout where the user must enter the letters
When I click any button on the grid this is the pop up window which is displayed.
If I run this , the app is getting stopped.
It might help us if you would share the exact exception that is thrown by your application.
If I unterstand you correctly, then b1 is a button contained in your activity_popup- layout. So you might want to try b1 = (Button) container.findViewById(R.id.b1) instead. If thats not working, post your exception!
My program asks a user to enter their name and click on a button called btn. Once btn is clicked, their name is dynamically added to a TableRow along with another dynamically created Button. It's these Buttons that I'm having an issue with. I need to somehow access them later on in the program. I created a number of IDs in my res/value folder to keep track of each one(changebtn1, changebtn2, etc..). They're all stored in an array called buttonIDs.
Let's say that the user enters the first name, a new row is created with a dynamically created button:
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
tableRow = new TableRow(getApplicationContext());
Button changeButton = new Button(getApplicationContext());
changeButton.setText("Change");
changeButton.setId(buttonIDs[i]);//From res/values
tableRow.addView(changeButton);
tableLayout.addView(tableRow);
i++;
});
Now let's say they enter a second name, another Button is created and so on and so forth. How can I now set an OnClickListener to my first Button that I created, which has the ID of R.id.changeBtn1? In other words, I have all of these dynamically created buttons and am not sure how to add OnClickLsteners() to earlier ones or access them in anyway. Thank you
Or you attach the OnClickListener directly in the creation of the button or you can store the references to the buttons like this:
ArrayList<Button> buttons = new ArrayList<Button>();
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
tableRow = new TableRow(getContext());
Button changeButton = new Button(getContext());
buttons.add(changeButton);
changeButton.setText("Change");
changeButton.setId(buttonIDs[i]);//From res/values
tableRow.addView(changeButton);
tableLayout.addView(tableRow);
i++;
});
for(Button button: buttons){
button.setOnClickListener(new OnClickListener()
...etc...
);
}
You won't waste a lot of memory since the buttons.add() line won't copy the button in the array but just the reference to the button. If you need a in id access to the buttons, use an HashMap, like this:
HashMap<String, Button> map = new HashMap<String, Button>();
map.put("id", new Button(getContext()));
And then access it like this:
Button button = map.get("id");
How about something like this
for(int i=0;i<buttonIDs.size();i++) {
Button currentButton = (Button) findViewById(buttonIDs[i]);
currentButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Stuff
}
});
}
I did not check the code
#filnik The first part of your answer also gave me an idea. I created an OnClickListener method outside of my OnCreate() method.
View.OnClickListener changeTeamName(final Button button) {
return new View.OnClickListener() {
public void onClick(View v) {
//Do Stuff
}
};
}
I then set an OnClickListener to EACH dynamically created Button and use the method that I created.
changeButton.setText("Change");
changeButton.setTag("ButtonOne");
changeButton.setOnClickListener(changeTeamName(changeButton));
The fact that each Button now has an OnClickListener associated with it, they can now perform whatever function I add to my method.
I have 12 buttons in my activity..i want to use them in the following way:
Two buttons should be allowed to click at once and when those two are clicked then some action to be performed..if this action is successful, these two buttons must be "invisible" and if this action is unsuccessful, again there must be option to click any of the two buttons out of all twelve..
i have set the layout of this activity and all the twelve buttons as well.I have also set the onClick method for all of the buttons.
[ADDITION]
i mean only two out of twelve buttons be allowed to press at once..any two of them..and after that the output of both the buttons be compared..if they are equal then the buttons be invisible else they are still there and once again the user gets a chance to click two buttons..
[CODE]
button1.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
// TODO Auto-generated method stub
RotateAnimation rotate = new RotateAnimation(0,90);
rotate.setFillAfter(true);
button1.startAnimation(rotate);
Random r = new Random();
int next = r.nextInt(5) + 1;
imgV1.setImageResource(images[next]); //imageView1 is given a random image
AlphaAnimation alpha = new AlphaAnimation(0,1);
alpha.setFillAfter(true);
imgV1.startAnimation(alpha);
arg0.clearAnimation();
}});
imgV1.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
// TODO Auto-generated method stub
AlphaAnimation alpha = new AlphaAnimation(1,0);
alpha.setFillAfter(true);
imgV1.startAnimation(alpha);
RotateAnimation rotate = new RotateAnimation(90,0);
rotate.setFillAfter(true);
button1.startAnimation(rotate);
arg0.clearAnimation();
}});
button click gives a random image..image click gives the button back..now i want that when two buttons are clicked and if they have the same image, then they both go invisible..else they both turn back to the buttons and user can again click on any of the two buttons..
Each button has an imageView behind it in the layout..
K.. Now I got it. So, there will be 6 images in your Drawable. Here we go..
Make an Integer array of size 12 to store id's of 6 images. say, int[] images={R.drawable.img1,...};
Also Button firstClick;Drawable back; to know the first clicked button.
Now, our onClick will be as,
findViewById(R.id.button1).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if(count<2){// means first click
firstClick=(Button)v;
back=v.getBackground();
action=images[0];// button1 pressed so index 0
v.setBackgroundResource(action);
v.setEnabled(false);
count++;
}
else{//second click
count=0;
if(action==images[0]){
v.setBackgroundResource(action);
v.setEnabled(false);
}else{
v.setBackgroundDrawable(back); //roll back to old background
firstClick.setBackgroundDrawable(back);
}
}
}
});
You can use setVisibility() method of view(Button) to set it's visibility on or off.
Button b = ( Button )findViewById( R.id.button1 );
b.setVisibility( b.INVISIBLE );
b.setVisibility( b.VISIBLE );
The logic that I thought is like,
You should have two variables in hand globally.
1 for counting button clicks and 2nd for storing first click action(Based upon your app).
I'm taking int action=0,count=0; as global variables.
findViewById(R.id.button1).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if(count<2){// means first click
action=1;// button1 pressed
count++;
}
else{//second click
count=0;
//Here perform your action and based upon it, set visibility. Previous click is available in 'action'
}
}
});
Repeat this for all button clicks. Thats it. I'll prefer your own method to be called for perform actions and set visibility.
I have a Layout with a TextView. The TextView has
android:autoLink="all"
How can I achieve the following:
if user clicks a link, an action associated with that link is executed (i.e., click on phone number invokes dialer, etc.)
if user clicks anywhere else within Layout boundaries, Layout's onClick is called.
Thanks.
Attach an oclicklistener to the TextBox layout, and handle it from there.
TextView txt = (TextView) findViewById(R.id.yourTextBoxId));
txt.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
// USer Clicked the textBox
}
});
The same apply for the Layout, find it and ...
layout.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
// USer Clicked the layout
}
});
I hope it helps.
I'm creating buttons dynamically ...
for(int i=0; i<colSize;i++){
final Button btn = new Button(this);
btn.setText(SectionName[i]);
btn.setTextSize(10);
btn.setPadding(8, 3,8, 3);
btn.setTextColor(Color.WHITE);
btn.setTypeface(Typeface.SERIF, Typeface.BOLD);
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//***Every time that I click my button is selected !:)
btn.setSelected(true);
}
});
}
But how could I deselect the other buttons that were selected, I just want one Button selected! :)
The brutal way (works if you have few buttons) - save your button references and create private method which loops through your buttons and deselects once you don't need
Extend your button class and make it listen for custom event which is generated when one of the buttons is clicked
Look at the RadioGroup implementation
Variation of #1. Instead of creating separate listeners for your buttons create just one and reuse it for all buttons. Extend that listener from OnClickListener and add List field. Each time you assign listener to the button add button reference to that list. Now, when onClick is triggered simply loop through the list and disable "other" buttons
Declare a variable to store the Id of the Clicked Button ::
private int EnabledButton;
set an ID on every button when are created ::
btn.setId(i);
or a tag ::
btn.setTag(i);
then in that Listener get the "EnabledButton", and call a function to deselect the other buttons::
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
EnabledButton=btn.getId();
DeselectButtons();
btn.setSelected(true);
}
});
The Function to deselect the other Buttons ::
public void DeselectButtons() {
for(int i=0; i<NumberofButtons;i++){
if (EnabledButton!= i)
this.findViewById(i).setSelected(false);
}
}
