膨胀类Button Android studio时出错

Question

我正在Android Studio中制作一个应用程序，在向MainActivity添加按钮以移动到其他活动后，尽管事实上布局在编辑器中显示正确，但我得到了错误，将在最后发布。在我的项目中还有其他的活动，我没有包括在内，因为错误指的是activity_main.xml，但如果它们是解决这个问题所必需的，我将包括它们。

这里是activity_main.xml。

<?xml version="1.0" encoding="utf-8"?>
<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"
tools:context=".MainActivity">

<ImageView
    android:id="@+id/view_img_main_menu"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:adjustViewBounds="true"
    android:src="@drawable/grocery_img_1" />

<Button
    android:id="@+id/btn_inventory"
    android:layout_width="match_parent"
    android:layout_height="65dp"
    android:layout_below="@id/view_img_main_menu"
    android:text="@string/btn_my_groceries_text"
    android:theme="@style/BtnTheme" />

<Button
    android:id="@+id/btn_shopping_list"
    android:layout_width="match_parent"
    android:layout_height="65dp"
    android:layout_below="@id/btn_inventory"
    android:text="@string/btn_shopping_list_text"
    android:theme="@style/BtnTheme" />

</RelativeLayout>

这里是MainActivity:

public class MainActivity extends AppCompatActivity {

private Button btnInventory;
private Button btnShopList;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    btnInventory = findViewById(R.id.btn_inventory);
    btnShopList = findViewById(R.id.btn_shopping_list);

    btnInventory.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent inventoryIntent = new Intent(MainActivity.this, Inventory.class);
            startActivity(inventoryIntent);
        }
    });

    btnShopList.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent shopListIntent = new Intent(MainActivity.this, ShoppingList.class);
            startActivity(shopListIntent);
        }
    });
}

这是我在运行代码时得到的错误。

这里是 styles.xml:

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:windowBackground">@color/colorLayoutBackground</item>
</style>

<style name="BtnTheme" parent="TextAppearance.AppCompat.Widget.Button.Colored">
    <item name="colorButtonNormal">@color/colorViewBackground</item>
</style>

<style name="TextViewTheme" parent="">
    <item name="android:background">@drawable/rounded_corners</item>
    <item name="android:textColor">@android:color/white</item>
</style>

我试着改变错误所指的Button的属性（第15行，btn_inventory），但没有任何进展。以前没有遇到过这个错误，也不太明白问题出在哪里。我该怎么改才能让它正常工作？看了一下关于同样错误的帖子，我的问题没有得到答案，这个错误出现的原因似乎有不少。

Answer 1

在两个按钮标签改变

android:theme="@style/BtnTheme" 

到

style="@style/BtnTheme"
