如何让我的矩形显示文字，但我甚至无法显示矩形？

Question

Im trying to get this code to work for my android app, but I can't get my rectangle to show up and I don't know how to put text into this rectangle.

This is my shape.xml file

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="rectangle">
    <stroke android:width="1dp"
        android:color="#ababab"
    />

    <padding android:left="1dp"
         android:top="1dp"
         android:right="1dp"
         android:bottom="1dp"
     /> 

    <corners android:bottomRightRadius="7dp" android:bottomLeftRadius="7dp" 
     android:topLeftRadius="7dp" android:topRightRadius="7dp"/>  
</shape>

This is my fragment_task.xml

<GridLayout xmlns:android="http://schemas.android.com/apk/res/android">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/shape"
        android:orientation="vertical"
        android:layout_marginRight="10dp"   
        android:id="@+id/linearLayout">

    </LinearLayout>

</GridLayout>

The linear layout is set to wrap content and has nothing inside. What you probably want to do is putting the text view into the linear layout, so simplty move it, or just remove the linear layout and set the textview background to your drawable.
