ListView 应用程序中的 EditText 崩溃答案

【问题标题】：EditText in ListView App CrashesListView 应用程序中的 EditText 崩溃
【发布时间】：2013-04-07 12:10:13
【问题描述】：

我在同一活动上有 2 个 listView，其中每行都有一个 EditText。

第一个问题：每当我尝试在一个 EditText 中写一些东西时行文本要么不显示，要么用一种奇怪的语言。

第二个：当我写完“这不起作用”时，如果我按下后退按钮，使键盘消失应用程序崩溃。

另一方面，如果我按下 EditText，那么键盘就会出现，然后在不写任何东西的情况下按下它就可以正常工作..

谢谢。

【问题讨论】：

标签： android android-listview android-edittext

【解决方案1】：

您是否在 SDK 级别 16 上运行？ It may be related to this problem.

还要确保您不会不小心将资源 ID 提供到 TextView 的 setText()：

holder.id.setText(getId(getItem(position)));

在没有看到您的代码的情况下，getId() 可能会返回一个 int，而您可能希望将其结果指定为字符串：

holder.id.setText(String.valueOf(getId(getItem(position))));

【讨论】：

我用getId public String getId(HashMap<String, String> item){ return item.get(TAG_ID).toString(); }返回一个字符串
getName() 和 getQuant() 怎么样？
它们都在返回字符串，这个 listView 工作正常，直到我添加了 editText。我有一个假设，但不确定。我的 listView 包含在另一个视图中，当键盘弹出时它位于屏幕底部，它将所有组件向上移动。我想知道这是否会导致 listView 出现任何问题。如果可能的话？是否有任何修复..整个视图在 FrameLayout 上的另一件事..不确定所有这些是否有帮助
实际上要添加我的 logcat 中有一个部分显示 spannable.StringBuilder 不能为零
我找到了解决办法。在那个答案link 中，在我将其更改为android:inputType="textNoSuggestions" 之后，EditText 输入出现了问题
