toolbar 设置paddingtop 一直报错
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:background="@color/colorPrimary"
app:theme="@style/ThemeOverlay.AppCompat.ActionBar"
android:paddingTop="@dimen/tool_bar_top_padding">
<TextView
android:id="@+id/toolbar_title"

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:textStyle="bold"
android:textColor="@color/md_white_1000"
android:text="@string/app_name"/>
</android.support.v7.widget.Toolbar>
现以下错误
FATAL EXCEPTION: main Process:
android.view.InflateException: Binary XML file line #2: Error inflating class android.support.v7.widget.Toolbar
Caused by: java.lang.reflect.InvocationTargetException
Caused by: java.lang.UnsupportedOperationException: Can't convert to dimension: type=0x1
错误来源:
Can't convert to dimension: type=0x1找不到dimension
原因android:paddingTop="@dimen/tool_bar_top_padding"只定义在values-21文件夹中, 到5.0以下系统运行时就会出现该错误
