- 1.因为Webview和ScrollView都用滑动事件,导致webview很难被滑动,即使被滑动了一点也非常不顺畅
- 2.解决滑动冲突问题后发现,如果webview嵌套的html中含有轮播图等还是有问题。
使用自定义ScrollWebView解决这个问题
public class ScrollWebView extends WebView{
private float startx;
private float starty;
private float offsetx;
private float offsety;
public ScrollWebView(Context context) {
super(context);
}
public ScrollWebView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public ScrollWebView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
@Override
public boolean onTouchEvent(MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
getParent().requestDisallowInterceptTouchEvent(true);
startx = event.getX();
starty = event.getY();
Log.e("MotionEvent", "webview按下");
break;
case MotionEvent.ACTION_MOVE:
Log.e("MotionEvent", "webview滑动");
offsetx = Math.abs(event.getX() - startx);
offsety = Math.abs(event.getY() - starty);
if (offsetx > offsety) {
getParent().requestDisallowInterceptTouchEvent(true);
Log.e("MotionEvent", "屏蔽了父控件");
} else {
getParent().requestDisallowInterceptTouchEvent(false);
Log.e("MotionEvent", "事件传递给父控件");
}
break;
default:
break;
}
return super.onTouchEvent(event);
}
}
