推荐答案

如果您的布局有TabHost（或类似的布局或视图）， TabHost的孩子可能会扰乱你的WebView的焦点。

If your layout have TabHost (or similar layout or view), TabHost's child may disturb your webview's focus.

我有同样的问题，我将这些观点的可成为焦点ATTR为假，并能正常工作。

I have same problem and I set these view's focusable attr to "false" and works fine.

for (int i = 0; i < tabHost.getTabWidget().getChildCount(); i++) {
  tabHost.getTabWidget().getChildAt(i).setFocusable(false);
}
