android XML视图在Eclipse中不显示ToggleButton [英] android XML view Does not display ToggleButton in Eclipse

问题描述

在我的Android XML图形布局中，我无法显示我的 ToggleButton 。我收到一些错误（见下文）。此外，我无法使用图形布局编辑任何其他内容。

In my android XML Graphical Layout, I am unable to display my ToggleButton. I receive some errors (see below). Also, I am not able to edit anything else using the Graphical Layout.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.thunder4apps.lanterna.corinthians.MainActivity" >



    <ToggleButton 
    android:id="@+id/togglebutton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textOn="Vibrate on"
    android:textOff="Vibrate off"
    android:onClick="onToggleClicked"/>


</RelativeLayout>

错误：

Exception raised during rendering: -1
Exception details are logged in Window > Show View > Error LogThe graphics preview in the layout editor may not be accurate:
Different corner sizes are not supported in Path.addRoundRect. (Ignore for this session)
Path.isConvex is not supported. (Ignore for this session)

推荐答案

转到您的图形布局并找到API级别的下拉菜单，可能您正在使用最后一个21，并且您没有安装它，根据您的应用更改为其他杠杆。

Go to your graphical layout and locate the drop down of the API levels, probably you are using the last one 21, and you don´t have it installed, change to other lever according to your app.
