致命崩溃：焦点搜索返回了无法获得焦点的视图

问题描述

当我在EditText中输入内容时，我的应用程序不断崩溃，但这种情况在某些情况下不会发生。我正在三星Galaxy Tab 2 10.1 WiFI上运行我的应用程序。 3G（GT-P5100）与Android 4.0.4（ICS）。我使用股票键盘。

My application keeps crashing when I type something in a EditText, but this does not happen always only in some cases. I am running my app on a Samsung Galaxy Tab 2 10.1 WiFI & 3G (GT-P5100) with Android 4.0.4 (ICS). I use the stock Keyboard.

这是我的logcat：

这是我的一个EditTexts：

This is my one of my EditTexts:

    <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" />

推荐答案

我遇到了同样的崩溃，尽管它并没有听起来像确切的情况，也许这仍然会有所帮助：

I was having this same crash and although it doesn't sound like the exact situation, perhaps this will still be helpful:

我有两个EditText框。最下面一个是前一个下一个焦点。在某些情况下我会隐藏底部的盒子，所以当我从顶部盒子敲击键盘的下一个时，它会尝试去底部，但是因为它被隐藏会崩溃。我通过将底部框（另一个EditText的Next Down Focus的目标）设置为不可聚焦来修复此问题：

I had two EditText boxes. The bottom one was the Next Focus Down of the top one. In some situations I would hide the bottom box, so when I hit next on the keyboard from the top box, it would try to go the bottom one, but would crash since it was hidden. I fixed this by setting the bottom box (the target of another EditText's Next Down Focus) as not focusable:

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

我希望这有帮助。
