6）这是我的日志猫
7）此代码运行启动画面但是当5000ms完成时它会崩溃????
答案 0 :(得分：2)
来自LogCat：
Caused by: java.lang.UnsupportedOperationException: Can't convert to dimension: type=0x3
at android.content.res.TypedArray.getDimensionPixelSize(TypedArray.java:463)
at android.widget.TextView.<init> (TextView.java:898)
at android.widget.TextView.<init> (TextView.java:556)
我认为文本大小不能用字符串表示。
<TextView
...
android:textSize="@string/text_size" />
尝试为所有视图对此值进行硬编码：
<TextView
...
android:textSize="16sp" />
如果有效，请查看Styles and Themes，了解为每个视图设置一个文字大小的适当方法。
