Android Scrollview没有抓住longclick

Question

如标题中所述,我有一个滚动视图应该是在听longclicks,但是没有抓到任何.当我按住滚动视图时没有任何事情发生 - 没有日志,没有触觉反馈,也没有对话框.

提前致谢!

JAVA:

...
ScrollView text_sv = (ScrollView) findViewById(R.id.text_sv);
    text_sv.setOnLongClickListener(new OnLongClickListener() {
        @Override
        public boolean onLongClick(View v) {

            MMMLogs.i("click", "long-click recognized");

            AlertDialog.Builder builder = new AlertDialog.Builder(_this);

            builder
            .setTitle(name)
            .setMessage(DHMenuStorage.notification)
            .setCancelable(false)
            .setNegativeButton("Close", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    dialog.cancel();
                }
            });
            AlertDialog alert = builder.create();
            alert.show();

            return true;
        }

    });
...

好吧,我从来没有确定我的问题的确切来源,但我怀疑它与滚动视图需要自己滚动的听众有某种冲突.

我通过在linearlayout而不是scrollview上设置完全相同的侦听器来解决此问题.简单.希望能帮助到你!
