二进制 XML Line#0 膨胀异常？答案

【问题标题】：Binary XML Line#0 inflate exception?二进制 XML Line#0 膨胀异常？
【发布时间】：2017-12-11 09:37:13
【问题描述】：

每次我尝试运行我的应用程序时都会收到此错误，我不知道为什么我试图为我的应用程序制作一个基本的欢迎屏幕，然后将转换到我的主页，但目前欢迎屏幕没有加载并且当我运行项目时，应用程序只是说“无法运行应用程序”。我已尝试对项目进行干净的构建和重建，并针对其他人遇到的此错误进行其他修复，但仍然没有运气。

下面我发布了 logcat 在运行时给出的错误。

这是我的 MainActivity 代码：

public class MainActivity extends AppCompatActivity 

{

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
    setContentView(R.layout.welcome_screen);
}
}

这是我的 XMl 代码：

        android:layout_height="match_parent"

        <TextView

            />

        </LinearLayout>

</RelativeLayout>

有人可以帮我解决这个问题吗？

【问题讨论】：

您也可以发布welcomebackground 文件吗？因为你的错误是Caused by: android.content.res.Resources$NotFoundException: Resource "com.example.ross.moviepickerapp:drawable/welcomebackground" is not a Drawable (color or path)
什么是@drawable/welcomebackground
检查drawable/welcomebackground 是否可绘制？
抱歉修复它是一个 .jpg 图像，它位于我的可绘制 v24 文件夹中，但我将其更改为 .png 并将其放入修复它的可绘制文件夹中。

标签： android android-layout android-xml android-drawable

【解决方案1】：

你的线路可能有问题

android:background="@drawable/welcomebackground"

在 xml 文件中。尝试注释此行并清理项目并运行。

使用 new > empty Activity 创建一个新的 android Activity，看看是如何工作的。

【讨论】：

【解决方案2】：

Caused by: android.content.res.Resources$NotFoundException: Resource "com.example.ross.moviepickerapp:drawable/welcomebackground" (7f060064) is not a Drawable (color or path): TypedValue{t=0x1/d=0x7f060064 a=-1 r=0x7f060064}

你需要检查这个文件。

你可以通过Android Studio添加资源，进入app>res>drawable>"右键>新建>"Image Asset" or "Vector Asset"

【讨论】：

【解决方案3】：

不知道是不是和compiledSdkVersion和targetSdkVersion的android库版本有关。以前我在使用时遇到错误：

compileSdkVersion 26
targetSdkVersion 26
'com.android.support:appcompat-v7:26.1.0'
'com.android.support:design:26.1.0'

然后我更改为较新的版本并且它起作用了：

编译SdkVersion 27
targetSdkVersion 27
'com.android.support:appcompat-v7:27.0.2'
'com.android.support:design:27.0.2'

我希望这会有所帮助
