问题 How can I make my button's size to increase slightly when it is pressed and decrease again when it is released?

Using an OnTouchListener you can listen for different MotionEvents , such as ACTION_DOWN and ACTION_UP . 回答2: button.setOnTouchListener(new View.OnTouchListener() { @Override public

问题 I'm trying to change a TextView style based on its state. My styles.xml contains: <style name="text_normal_ops"> <item name="android:gravity">left</item> <item name="android:textColor">@color/text_usual_color</item> <item name="android:textStyle">bold</item> </style> <style name="text_normal_ops_pressed"> <item name="android:gravity">left</item> <item name="android:textColor">@color/text_pressed</item> <item name="android:textStyle">bold</item> </style> My selector ( text_ops.xml )is defined

问题 Problem description: I have a TextView on a RelativeLayout and I want to color it red when the user touches it, and go on another page when he clicks on it. So I tried to set an OnClickListener to do the click, and an OnTouchListener to implement the touch function ( MotionEvent.ACTION_DOWN ) but this combination doesn't work, because OnTouchListener makes OnClickListener non-functional (don't know why).
