关于这一点，我需要您的建议。
对于这一点，我想删除所有建议/自动更正：

}

}

switch (item.getItemId()){
case R.id.menu_back:

case R.id.menu_refresh:
superWebView.reload();
break;
}
return super.onOptionsItemSelected(item);
}
private void onForwardPressed(){
if (superWebView.canGoForward()){
superWebView.goForward();
} else {
Toast.makeText(getApplicationContext(), "Can't Go Further..!", Toast.LENGTH_LONG).show();
}
}
@Override
public void onBackPressed() {
if (superWebView.canGoBack()){
superWebView.goBack();
}else {
finish();
}
}
}
。
这将避免存储字典。
是否可以在没有root权限的情况下以编程方式清除用户词典？
