致命崩溃：焦点搜索返回的视图无法聚焦

Question

当我在EditText中键入内容时，我的应用程序不断崩溃，但这并不总是在某些情况下发生。我在装有Android 4.0.4（ICS）的Samsung
Galaxy Tab 2 10.1 WiFI和3G（GT-P5100）上运行我的应用程序。我使用库存键盘。

这是我的日志：

这是我的EditTexts之一：

    <EditText
    android:id="@+id/input_ftu_position_other"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginLeft="64dp"
    android:ems="20"
    android:inputType="text" />

Answer 1

我也遇到了同样的崩溃，尽管听起来不像是确切的情况，但这也许还是有帮助的：

我有两个EditText框。底部的是顶部的Next Focus
Down。在某些情况下，我会隐藏底部的方框，因此当我从顶部的方框中敲击键盘的下一个时，它将尝试移至底部的方框，但由于被隐藏而崩溃。我通过将底部框（另一个EditText的Next
Down Focus的目标）设置为不可聚焦来解决此问题：

    EditText inputBox = (EditText)findViewById(R.id.Bottom_Box);
    inputBox.setFocusable(false);

我希望这有帮助。
