EditText的布局是

<EditText
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:minHeight="88dp"
        android:isScrollContainer="true"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:layout_weight="1"
        android:gravity="left|top"
        android:inputType="textMultiLine"
        android:textAppearance="?android:attr/textAppearanceButton"
        android:hint="@string/Text"
        android:background="@drawable/edittextstyle"
        android:padding="10dp"
        android:textColor="@color/DARK_TEXT_COLOR" >
    </EditText>

没有编辑EditText的代码。只是布局。如果我将inputType属性更改为

文本

应用程序不会崩溃。我错了什么？

从此处更改您的代码：

<EditText
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:minHeight="88dp"
        android:isScrollContainer="true"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:layout_weight="1"
        android:gravity="left|top"
        android:inputType="textMultiLine"
        android:textAppearance="?android:attr/textAppearanceButton"
        android:hint="@string/Text"
        android:background="@drawable/edittextstyle"
        android:padding="10dp"
        android:textColor="@color/DARK_TEXT_COLOR" >
    </EditText>

To This：

<EditText
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:minHeight="88dp"
        android:isScrollContainer="true"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:layout_weight="1"
        android:gravity="left|top"
        android:inputType="textMultiLine"
        android:hint="@string/Text"
        android:background="@drawable/edittextstyle"
        android:padding="10dp"
        android:textColor="@color/DARK_TEXT_COLOR" >
    </EditText>

导致问题的xml代码的这一部分：

android:textAppearance="?android:attr/textAppearanceButton"

希望它有用

EditText StringIndexOutOfBoundsException
