OnClickListener不工作在列表视图

我正在创建一个搜索应用程序，我将XML文件解析到数据库中，然后使用searchview以列表视图返回结果。到那里，它工作正常。OnClickListener不工作在列表视图

但是，当我点击列表中的某个项目时，它不显示我希望显示的布局。我想要的是，当我点击列表视图中的一个项目时，它会显示一个新视图，该项目应该是book_info.xml布局文件。

我试图按照本教程BTW：http://www.mysamplecode.com/2011/11/android-searchview-using-sqlite-fts3.html?showComment=1418227703572#c6915997130457985000

屏幕截图，之前我点击：

我点击之后，它去之前，我做搜索！这是main.xml中

我的代码如下：

正如我看到你在onClickListener使用myList.getItemAtPosition(position);。据我所知，我们不能使用听众以外的任何视图，直到它是最终的。所以如果你想在onClickListener内使用myList，你必须做出最终决定。

我不认为这会工作。我已编辑我的帖子，并添加了一个screeen镜头。我认为导致问题的代码行如下： if（bookLayout == null）{ //膨胀客户信息视图 // LinearLayout leftLayout =（LinearLayout）findViewById（R.id.bookLayout）; View book = getLayoutInflater（）。inflate（R.layout.book_info，bookLayout，false）; bookLayout.addView（book）; bookLayout.addView（book）; } – user3460355

您只想显示一个被点击的项目。如果你添加了bookLayout，那么应该选择多个项目。 –

是的，这是我想要的。我该如何做到这一点，因为目前我正在用我尝试的任何方式获得原始屏幕。 – user3460355
