使用视图绑定膨胀类 ImageView 时出错

Question

我正在为我当前的应用程序使用 ViewBinding，但是遇到了问题。

在MainActivity中，我调用了xml的inflate，但是却显示如下错误

Error

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.foxcode.androidscreenmirroring/com.foxcode.androidscreenmirroring.view.MainActivity}: android.view.InflateException: Binary XML file line #11: Binary XML file line #21: Error inflating class ImageView

    at com.foxcode.androidscreenmirroring.view.MainActivity.onCreate(MainActivity.java:45)

...

这是xml代码和我调用的主要代码

activity_main.xml

<androidx.drawerlayout.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/drawerLayout"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context=".view.MainActivity">

    <include
        android:id="@+id/data"
        layout="@layout/layout_data" />

    <com.google.android.material.navigation.NavigationView
        android:id="@+id/nav_view"
        ... />

</androidx.drawerlayout.widget.DrawerLayout>

layout_data.xml

<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:tools="http://schemas.android.com/tools"
    android:background="@drawable/cst_background"
    >

    <include
        android:id="@+id/toolbar"
        layout="@layout/toolbar" />

    <androidx.constraintlayout.widget.Guideline
        android:id="@+id/guide"
        ... />

    // error in xml
    <ImageView
        android:id="@+id/btn_connect"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/cst_background_logo"
        android:onClick="connect"
        android:padding="20dp"
        android:src="@drawable/ic_connect_wifi"
        android:tint="#EEFBFBFB"
        app:layout_constraintBottom_toTopOf="@id/guide"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

MainActivity.java

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
// error in code
    binding = ActivityMainBinding.inflate(getLayoutInflater());
    setContentView(binding.getRoot());
}

我已经找到了很多方法，但仍然找不到解决方案，希望你能帮助。

谢谢大家

Answer 1

从ImageView 中删除android:background="@drawable/cst_background_logo" 这一行并

也改ImageViewdrawableandroid:src="@drawable/ic_connect_wifi"
