问题描述
我在Android应用中使用的是 SeekBar 。当用户在 SeekBar 上的任意位置单击时,其进度值将更改。我只希望在用户滑动 SeekBar 拇指时更改进度值(就像iOS中的 UISlider 一样)。
I am using a SeekBar in my Android app. When a user single taps anywhere on the SeekBar, its progress value is changed. I only want the progress value to change when the user slides the SeekBar thumb (just like a UISlider in iOS).
我尝试设置 SeekBar 为假,但这没有用。如何实现所需的行为?
I have tried setting the clickable property of the SeekBar to false but that didn't work. How can I achieve the desired behavior?
推荐答案我本周遇到了相同的问题,并使用自定义的SeekBar解决了该问题:遵循我的代码:
I faced the same issue this week and I resolved it using a custom SeekBar: following my code:
public class Slider extends SeekBar { private Drawable mThumb; public Slider(Context context) { super(context); } public Slider(Context context, AttributeSet attrs) { super(context, attrs); } @Override public void setThumb(Drawable thumb) { super.setThumb(thumb); mThumb = thumb; } @Override public boolean onTouchEvent(MotionEvent event) { if (event.getAction() == MotionEvent.ACTION_DOWN) { if (event.getX() >= mThumb.getBounds().left && event.getX() <= mThumb.getBounds().right && event.getY() <= mThumb.getBounds().bottom && event.getY() >= mThumb.getBounds().top) { super.onTouchEvent(event); } else { return false; } } else if (event.getAction() == MotionEvent.ACTION_UP) { return false; } else { super.onTouchEvent(event); } return true; }}希望这会有所帮助
