onclick

问题 My rows contain a button that has its own click listener set in my adapter's getView. I'm able to distinguish between my button clicks and the actual row item clicks using android:descendantFocusability="blocksDescendants" in the row's parent. When I click on a button it sets the button background properly, my problem is as I scroll through the list its setting it for different rows as well. I assume theirs an issue somewhere with views recycling. Here's my code: @Override public View getView

问题 Which tags can have an onClick function, and which cannot?

问题 I have placed image button on top of image view which is inside a CardView. I want to trigger some action when user clicks on Image button. However first problem is when I get the image button using findViewById inside MainActivity, it returns null(may be because image view is inside item_row xml which shows row data in the card view). The other problem is how to tackle such scenario where activity_main.xml is different which contains recycler view which has item_row.xml having image button

问题 Brief summary of my app: there are 2 buttons and a text view widget. Once the user clicks on the "Start" button, it will trigger a method in the that will shift the "main" button to another part of the screen. The text view will keep track of how many times the user clicks the "main" button.

问题 I am building an Android app using a pile of switch statements to switch between views. Everything was going fine until I added a block of cases that cause a fatal error when the app is starting up. The cases are called by onClick statements in the XML. The offending block of cases is actually part of a block of statements that work fine. Can anyone see what I'm missing? What's causing the fatal error? I'm including snippets of the broken code and working code along with the logCat file. 05
