应用程序在横向模式下崩溃

标签： android layout crash landscape

平板电脑/移动设备更改后，应用程序在重新启动时崩溃，

我将仅以横向模式开发应用程序，并且我在layout-land中创建了一个名为acitivty_main的布局，并且我的应用程序中没有任何纵向布局，也没有任何布局文件夹，我还添加了screenOrientation =清单活动中的“横向”。

活动代码关注： 

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {        
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    }
}

Manifest.xml代码如下： 

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.yasir.sample">

    <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=".MainActivity"
            android:screenOrientation="landscape">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

2 个答案:

答案 0 :(得分：3)

Resources$NotFoundException

  

请求时，资源API会抛出此异常   资源无法找到

<强> FYI

  • 移除 的 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

  • 在清单部分添加 android:configChanges="orientation|screenLayout" 。

Finally 

<activity android:name=".MainActivity"
                android:screenOrientation="landscape"
                 android:configChanges="keyboard|keyboardHidden|orientation|screenLayout">

然后 Clean and Rebuild 您的项目。
