Gostaria de saber se seria possível preencher uma TextView com o conteúdo de um arquivo PHP.
Não me refiro a visualização como em um WebView, gostaria de exibir o código com todas as tags:
Meu código até agora: res/layout/activity_php.xml
    <RelativeLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="center"
        android:background="@color/colorPrimaryDark" >
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="30dp"
            android:orientation="horizontal" >
            <Button
                android:id="@+id/btn_back"
                android:layout_width="40dp"
                android:layout_height="match_parent"
                android:background="@drawable/ic_back" />
            <TextView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:textAlignment="center"
                android:text="@string/title_php"
                android:gravity="center_vertical"
                android:textSize="20dp"
                android:textColor="@color/colorAccent" />
        </LinearLayout>
        <RelativeLayout
            android:id="@+id/view_php"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginTop="30dp"
            android:layout_marginBottom="30dp" >
            <TextView
                android:id="@+id/view_php_content"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:text="AQUI EU GOSTARIA DE EXIBIR O CONTEÚDO DO ARQUIVO PHP!" />
        </RelativeLayout>
        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="30dp"
            android:layout_alignParentBottom="true" >
            <Button
                android:id="@+id/btn_php"
                android:layout_width="wrap_content"
                android:layout_height="20dp"
                android:layout_centerInParent="true"
                android:text="Show content"
                android:textColor="@color/colorPrimaryDark"
                android:background="@color/colorAccent"
                android:textSize="8dp" />
        </RelativeLayout>
    </RelativeLayout>
