问题 I want to develop an unlocker. You can unlock by sliding to the right (just like on the iPhone). Wich is the best method to implement this? Should I use a ViewFlipper and a GestureDetector? I have already tried this, but I could slide anywhere on the screen to unlock. The ImageView of the ViewFlipper should slide with my finger and only if my finger is directly on the imageView. 回答1: Try looking at this question for gestures on images, or any view for that matter. 来源： https://stackoverflow

问题 Basically I have a series of imageviews within a linear layout. I've set each of the imageviews layout width and layout height properties to 100dp and 50dp respectively (I've also tried px instead of dp and I've tried changing the imageviews max size) but the imageviews continue to scale rather than staying at this fixed size.
