Question

编辑：

对于带有ellipsize java.lang.ArrayIndexOutOfBoundsException:的TextView，我得到middle 例外。这是我的TextView

        <TextView
        android:id="@+id/textView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="25dp"
        android:layout_marginRight="25dp"
        android:ellipsize="middle"
        android:maxLines="1"
        android:paddingLeft="10dp"
        android:paddingRight="27dp"
        android:text="123456 123 1234567890123456"
        android:textSize="16sp" />

我已尝试使用此异常，并使用此给定的margin，padding，textSize和singleLine导致calculateEllipsis()方法。

这是 CrashLog

以下是我未获得例外

的情况

如果我删除最后一个字符（设置文字＆＃34; 123456 123 123456789012345＆＃34;删除＆＃39; 6＆＃39;从最后一个）那么我就不会得到例外
如果我设置textSize 14sp ，那么我就不会有任何异常
如果我设置了ellipsize =＆＃34;结束＆＃34;它运作良好。
它在具有相同TextView属性的高分辨率设备中工作正常。

我认为使用大字和＃34; 1234567890123456＆＃34;制作 ellipsize middle （16个字符）导致此异常。

这是我的设备规格：

型号： HUAWEI Y320-U30
Android 版本：4.2.2

任何人都可以解释这种情况下calculateEllipsis()方法的错误。

提前致谢。

Answer 1

我得到了答案。如果我同时使用android:ellipsize="middle"和android:maxLines="1"，那么前lolipop设备会出现错误。解决方案是使用android:singleLine="true"。这可以防止我的崩溃。这是bug report。您也可以查看answer
