Question

我有自定义的scrollview编写，没有来自平板电脑的手写笔工作正常。使用Tablet手写笔时，即使禁用了滚动功能，此customScrollview也允许手写笔执行滚动。

public class CustomScrollView extends ScrollView {

    private boolean enabled = false;

    public CustomScrollView(Context context) {
        super(context);
    }

    public CustomScrollView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomScrollView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        return enabled;
    }

    public void setEnabled(boolean enabled) {
        this.enabled = enabled;
    }

    public boolean getEnabled() {
        return this.enabled;
    }
}

Answer 1

你可以尝试一下。

Answer 2

试试这个：

@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
    if (ev.getToolType(TOOL_TYPE_STYLUS)) { 
        // also, here you should check if it should be disabled at this point
        return !enabled;
    } else {
        return enabled;
    }
}

覆盖onInterceptHoverListener诀窍。现在，如果启用了scrollview，则会处理Stylus onhover滚动，一旦scrollview enabled = false，就不会处理相同的滚动。

    public class CustomScrollView extends ScrollView {

        private boolean enabled = false;

        public CustomScrollView(Context context) {
            super(context);
        }

        public CustomScrollView(Context context, AttributeSet attrs) {
            super(context, attrs);
        }

        public CustomScrollView(Context context, AttributeSet attrs, int defStyleAttr) {
            super(context, attrs, defStyleAttr);
        }

        @Override
        public boolean onInterceptTouchEvent(MotionEvent ev) {
            return enabled;
        }

        public void setEnabled(boolean enabled) {
            this.enabled = enabled;
        }

      @Override
        public boolean onInterceptHoverEvent(MotionEvent event) {
   if (this.enabled)
        {
            return false;
        }
        else
        {
          return true;
        }

}

       public boolean getEnabled() {
            return this.enabled;
        }
    }

如何禁止Scrollview滚动手写笔？
