How to change button image on click?

由 痴心易碎 提交于 2019-12-12 03:56:27
问题 I am using images and hrefs to create buttons. Code look like this: <a href="http://www.zive.sk"><img src="res/images/zive.png" alt="Zive.sk" id="ziveCircle"></a> Is there any way to change image src if user press button? Maybe some event handler which will determine that user has pressed image? It should act as normal button so when user press it and keep pressed it should change image src and when he releases the button then the href should be loaded (normal button behaviour). PS: I cannot

Test if a javax.swing.JButton is pressed down

由 |▌冷眼眸甩不掉的悲伤 提交于 2019-12-11 02:55:24
问题 I would like to check whether a certain javax.swing.JButton (regular push-button) is pressed down (before it was released). Is there any option at all to check whether a button is down? The most trivial solution is to add a MouseListener that will respond to the mouse click and release events. But, this does not cover the case where the button was activated by the Enter key, or any other way. I don't want to disable activating the mouse by keyboards or other ways - I just want to know when is

问题 My button consists of only letters. Every time i press it, it has a black background. How do i disable the black background? I don´t want to change the color, i want to disable the pressed state. 回答1: You need to create selector under drawable folder and set color or image over there for different sates of the button. I have created one sample application for you and am pasting code snippet: Code for button_selector.xml that contains selector code for button which you will need to put under

Java KeyListener - How to detect if any key is pressed?

由 青春壹個敷衍的年華 提交于 2019-12-08 08:16:00
问题 I've added a KeyListener to a TextArea and wish to check if any key is pressed down. I have the following but it's too clumsy to check for all the letters and numbers: public void keyPressed(KeyEvent e) { if(e.getKeyCode() == KeyEvent.VK_A || e.getKeyCode() == KeyEvent.VK_B || e.getKeyCode() == KeyEvent.VK_C ||e.getKeyCode() == KeyEvent.VK_D etc...){ } } 回答1: You wouldn't need any if statements. The keyPressed method is fired whenever a key is pressed, so you're automatically thrown into the

To increase a button's size when it is pressed in Android

由 荒凉一梦 提交于 2019-12-06 09:27:30
How can I make my button's size to increase slightly when it is pressed and decrease again when it is released? This is for highlighting the pressed button, by using size in addition to a different color. Regards, Kiki Make your Button a field, and modify its size in the OnTouchListener associated with it. Using an OnTouchListener you can listen for different MotionEvents , such as ACTION_DOWN and ACTION_UP . button.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { RelativeLayout.LayoutParams layoutParams = (RelativeLayout
