InflateException 在特定情况下，我错过了什么？答案

【问题标题】：InflateException at spefic case, what am I missing?InflateException 在特定情况下，我错过了什么？
【发布时间】：2019-10-16 12:17:18
【问题描述】：

当 ChatActivity 不是 LAUNCHER 活动时，我从 ChatActivity 收到 InflateException，但当我更改清单以使 ChatActivity 是 LAUNCHER 时，应用程序可以正常工作。我可能遗漏了什么，代码中是否遗漏了什么？

16.10 18:15 更新 - 我发现如果我删除

implements View.OnClickListener

从 LoginActivity 应用程序工作（但现在我没有按钮）。这个问题的原因是什么，如何解决？

产生错误时的部分清单 -

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".Activities.LoginActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".Activities.ChatMainActivity"></activity>
    <activity android:name=".Activities.RegisterActivity" />

如果我将文件更改为此（如下），聊天将正常工作 -

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".Activities.LoginActivity"></activity>
    <activity android:name=".Activities.ChatMainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".Activities.RegisterActivity" />

【问题讨论】：

你能发布你的 AppTheme 风格吗？
是的，我更新了帖子。 @SebastienRieu
你能发布完整的堆栈跟踪吗？
是的，我添加了它@paxcow
startActivity(new Intent(LoginActivity.this, MainActivity.class));您的清单中没有 MainActivity。是不是笔误？

标签： android android-inflate

【解决方案1】：

上传登录Activity代码，告诉我哪个是你的父类

【讨论】：

【解决方案2】：

你可以尝试添加

<item name="windowNoTitle">true</item>

你的主要风格，看看是否有效？

【讨论】：

这个错误很奇怪，它说android.support.design.widget.AppBarLayout 但是，你的依赖是材料设计库和android x。你能确保你的项目中没有任何 android.support.design.widget.AppBarLayout 的导入吗？另外，如果您更改了这些，清理并重新构建应用程序也可能会解决问题，如果您还没有尝试过
我尝试通过android studio搜索在所有文件中搜索android.support.design.widget.AppBarLayout，但没有找到任何东西

【解决方案3】：

Didn't find class "android.support.design.widget.AppBarLayout" on path 来自您错误地设置工具栏的活动：

mToolbar = (Toolbar) findViewById(R.id.main_app_bar);
setSupportActionBar(mToolbar);

您的工具栏由com.google.android.material.appbar.AppBarLayout 包裹。

因此无需将其添加到 supportActionBar。只需将您的活动主题定义为NoActionBar（在您的styles.xml 中）并在您的活动中删除setSupportActionBar(mToolbar);
