Question

我设计了一个没有任何功能的单个活动，只是为了查看UI是否会加载到我的VM（api24）中。它会加载一个空白活动，在加载任何字段之前，它会因以下错误而崩溃：

SDK中出现的预定义类中出现了很多错误。这是一个全新安装的Android Studio，带有一个新的项目文件。这是一个已编辑的空白活动。这是它的XML：

 <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.freek_000.bluetoothatendee.MainActivity">

<TextView
    android:text="       Login"
    android:layout_width="350dp"

    android:layout_marginTop="35dp"
    android:id="@+id/tLogin"

    android:layout_below="@+id/bLogin"
    android:layout_alignLeft="@+id/bLogin"
    android:layout_alignStart="@+id/bLogin" />

Answer 1

问题是由于编辑的文字无法使用背景。删除edittext字段的背景，它加载并运行正常

Answer 2

我认为这个解决方案不是很好；你的崩溃是因为你引用了错误的包；

<EditText
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:inputType="textPassword"
    android:ems="10"
    android:id="@+id/tPassword"
    android:backgroundTint="@drawable/toast_frame"
    android:background="@drawable/toast_frame"
    android:hint="Password"
    android:textColorHint="@color/background_light"
    android:layout_centerVertical="true"
    android:layout_alignLeft="@+id/editText"
    android:layout_alignStart="@+id/editText" />

"@android" 表示您想构建内部资源。但 "toast_frame" 来自您的应用。

资源$ NotFoundException：来自可绘制资源.xml扩展名的文件res / drawable-xxhdpi-v4 / toast_frame.9.png
