防止单击更改SeekBar进度 [英] Prevent single tap from changing SeekBar progress

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 clickable 属性>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;
}}
