我正在使用Android Studio，当我在布局应用程序中使用textview时关闭显示错误：

在我的片段类

中 
public class SubFragment extends Fragment{


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_homescreen, container, false);// getting error here


        return rootView;
    }


}

XML代码：

<LinearLayout
        android:layout_margin="10dp"
        android:layout_width="match_parent"
        android:orientation="vertical"
        android:gravity="center_vertical|center_horizontal"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:background="@drawable/offers">


        <ImageView
            android:id="@+id/imageButtonOffers"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_centerVertical="true"
            android:src="@drawable/offers_icon" />

        <TextView
            android:id="@+id/textViewOffers"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/imageButtonOffers"
            android:layout_centerHorizontal="true"
            android:layout_marginTop="5dp"
            android:gravity="center_horizontal"
            android:text="Offer"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:textColor="@color/white"
            android:textSize="15sp" />


    </LinearLayout>

这段代码与eclipse一起工作正常。我尝试在Studio工作时唯一的问题

答案 0 :(得分：12)

android:background="@drawable/offers"

我希望优惠是图片，它比屏幕大，所以用一些颜色代码替换n试试

喜欢这个

android:background="#ff0000"

希望它有效..

检查一下

android.view.InflateException: Binary XML file line #12: Error inflating class <unknown>

修改

删除此行

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

我清理了你的xml并添加了命名空间：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_margin="10dp"
    android:layout_weight="1"
    android:background="@drawable/offers"
    android:gravity="center_vertical|center_horizontal"
    android:orientation="vertical" >

<ImageView
    android:id="@+id/imageButtonOffers"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/offers_icon" />

<TextView
    android:id="@+id/textViewOffers"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="5dp"
    android:gravity="center_horizontal"
    android:text="Offer"
    android:textAppearance="?android:attr/textAppearanceMedium"
    android:textColor="@color/white"
    android:textSize="15sp" />

</LinearLayout>

当您使用LinearLayout时，参数如＆＃34; android：layout_below＆＃34;或者＆＃34; android：layout_centerHorizo​​ntal＆＃34;并非无效。

我也遇到了这个错误。

我通过简单地重新创建包含.xml的新TextView文件解决了这个问题。 就我而言，错误是xml版本（v21 \ abc.xml）。 代码在Android版本6（marshmallow）中运行良好，而不是在Android 4.4版（kitkat）中运行时抛出错误。

答案 3 :(得分：1)

我遇到了同样的问题。 确保在任何布局中没有 tools:targetApi="lollipop"。相反，在layout下有两个布局，在layout-v21文件夹下添加另一个布局。

答案 4 :(得分：0)

似乎旧版本的Android不支持这样的标签

android:background="@drawable/rounded_corner"
android:textSize="?android:textAppearanceMedium"

在这种情况下，请将其从XML文件中删除，然后尝试从Java或Kotlin代码中加载属性（最好在try ... catch或if ... else子句中）

希望有帮助

答案 5 :(得分：0)

您必须在项目的res->字体文件夹中创建另一个.xml文件。之后，调用.xml文件中的字体文件。 

<font
    android:font="@font/rubikbold"/>

在这里，我的项目中有一个robik粗体字体文件。

答案 6 :(得分：-1)

我遇到了类似的错误，但是我发现属性textAppearance没有正确编写。

最初是android:textSize="?android:textAppearanceMedium"而不是android:textAppearance="?android:textAppearanceMedium"
