In my app I have one button which works as "pause" and "Resume". Here user can click this button manually to pause and resume. And somethimes I am performing click programatically using view.performClick() method.
The question is....is it possible to know by which click button clicked ?
Thanks
Edit:
I am using timer in my app and I want to pause and resume timer.
Handle the click in a different method:
private void handleClick(boolean manualClick) {
//your code...
}
public void onClick(View view) {
handleClick(true);
}
and do not use view.performClick() to call it automaically, but call handleClick(false)
You can set the flag true/false when click manually, and use that while performing click operation.
if(button.getText().toString().trim().equalsIgnoreCase("pause")){
// puse your timer here or whatever you would like
}else{
//resume your time here or whatever you would like
}

I have a button that calls another button2's performClick(). I want to know if there is any way to check or distinguish if the button2's click is performed programmatically or not.
button.setOnClickListener {
button2.performClick()
}
Let's say I'm sending a request in button2's onClick() method. Can the system that I'm sending this request detect whether I performed this click via not actual click but this performClick() function.
A simple way to do this is to save a boolean value when the click is invoked via the performClick. Example
button2.setOnClickListener {
//The click here is performed by clicking on the button itself
buttonFunctionality();
}
button1.setOnClickListener {
//Button 2 click performed via Button 1
performedProgrammatically = true;
buttonFunctionality();
}
So I have a button with a onClick method like this:
public void myClickHandler(View v){
}
I have multiple checkboxes on one page, and when that button is pressed it will start a timer on all of the checked boxes. Also, most of the timers have different times. Have any ideas on how I can get this working? Thanks!
i think,you can use one timer,or just one thread.computing and send different broadcasts or the same broadcast with different args,handle and dispatch in the method onReceive;
While developing an android app, I have an activity with some buttons. I would like the onClickListener action to start when the user puts his finger on the screen immediately so he isn't able to click two buttons at once.
I do that in iOS by using the touchDown event rather than the default TouchUpInside.
I have absolutely no idea of how this can be done in Android...
Android code :
button.setOnClickListener(clicked);
[...]
View.OnClickListener clicked = new View.OnClickListener() {
public void onClick(View v) {
//Cool stuff there
}
}
thanks for helping !
What you are looking for is using an OnTouchListener instead of the OnClickListener. This will allow you to react upon the first touch of the button and stop reacting on other button touches until the first touch is stopped again.
You can disable the other buttons when you start the click and re-enable them when you are finished.
By default the buttons clicks will be handled on the same thread so their actions would not complete in parallel even if you do not disable them.
I am creating an app which consists of main, register, option activities. Main and register activities should be started only once. I got it. Problem is they are again appearing when I just going back to my mobile home page without clicking exit. Even if I do not click the exit and goes back to home, they should not appear again when I entered!! Is this possible? I am not able to get the solution for this. Any one please help me.. Thankyou
you can override the method onStop() and put finish() there.
So, when the activity will be not longer visible, it will finish. Or you can put finish() after startActivity() call method.
you can do this by.
Button button15 =(Button)findViewById(R.id.button5);
button15.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
finish();
}
}
);
I want to be able to press a button on my program and hold it down (without releasing) to increment a variable. Problem I am having right now is when I conduct the long button press it only runs once, until I release and press again.
First I want to find out if there is a way to do this without having to use the OnTouchListener, and just using the OnLongClick. Is there a way to check the value of the button? For example.. buttondown=true; Conduct a whileloop to increment until the button is released.
Second, I don't want the updates to be delayed, because the incremented value is being drawn as the user holds down the button.
Basically I am doing something like this:
btn_resume.setOnLongClickListener(new OnLongClickListener() {
public boolean onLongClick(View v) {
..code..
return true;
}
});
OnLongClick will only be called once per press. It isn't going to work for your purpose.
If I understood your question correct this can be achieved using a OnLongClickListener.
Check http://developer.android.com/reference/android/view/View.html#setOnTouchListener(android.view.View.OnTouchListener)
OnTouchListener provides a more granular handling of touch events, e.g. KeyDown, KeyUp
I think you can use OnLongClickListener for increment/decrement. But once the long press is done for the button, the longpress has to be canceled or reset for the next long press of the same button.
