无论如何，有没有要从视图对象中删除onTouchListener? [英] Is there anyway to remove an onTouchListener from a view object?

问题描述

我有一个用于Webview的触摸式侦听器，但是它对Webview的功能有不好的影响，所以我想知道在最初的交互之后是否还有删除触摸式侦听器的方法?

I have an on touch listener for a webview, but it has a bad effect on the functionality of the webview, so I am wondering if there is anyway to removed the on touch listener after the initial interaction?

推荐答案

因此，在您进行活动时，您将设置覆盖的onTouchListener:

So in you activity you would set your overridden onTouchListener:

            mWebView.setOnTouchListener(new View.OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                v.setOnTouchListener(mWebView.mOnTouchListener);
                return false;
            }
        });

您将必须创建一个新类，扩展WebView.然后在其中定义一个OnTouchListener.

And you would have to make a new class, extending WebView. And within it you would define an OnTouchListener.

    public final OnTouchListener mOnTouchListener = new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent rawEvent) {
        return false;
    }
}; 

将ontouchlistener设置为null不会将其重置为默认定义.您仍然必须提供一个实际的侦听器.

Setting the ontouchlistener to null doesn't reset it to the default definition. You still have to provide an actual listener.
