hasSystemFeature(PackageManager.FEATURE_CAMERA) 对于没有相机的设备返回 true

我有一个使用相机功能的应用程序，但其部分功能也可以在没有相机功能的情况下运行。所以我已将其放入我的清单中。我有一个使用相机功能的应用程序，但其部分功能也可以在没有相机功能的情况下运行。所以我已将其放入我的清单中。 <uses-permission android:name="android.permission.CAMERA" /> <uses-feature android:name="android.hardware.camera" android:required="false"/> 在我的代码中，我使用此功能检查设备是否有摄像头 final boolean deviceHasCameraFlag = pm.hasSystemFeature(PackageManager.FEATURE_CAMERA); 现在我正在运行 Android 4.0(ICS) 并且没有摄像头的平板电脑上测试我的代码。但我仍然得到 deviceHasCameraFlag 的真实值。这很奇怪还是我错过了什么？我尝试了不同的方法，甚至在蓝牙功能上尝试了相同的方法，因为平板电脑甚至没有蓝牙功能。它适用于蓝牙，但适用于相机。它是什么设备？你得到的答案是一个错误，4.0 现在已经很老了。许多仍然运行此版本的平板电脑制作不正确，硬件和软件都存在多个问题。无论如何，您应该始终准备好处理 Camera.open() 或 Camera.open(0) 上的故障：例如，在某些情况下，设备上的其他软件不会正常释放相机。因此，在您的情况下，您有误报，您尝试打开相机，但失败了，并且您继续，就像设备上没有相机一样，即使PackageManager认为PackageManager.FEATURE_CAMERA可用。虽然我已经接受了 Alex 的答案，但我想把这个答案放在这里，展示如何处理硬件故障和错误。我的发现是在我的低标准 Android 设备的情况下 pm.hasSystemFeature(PackageManager.FEATURE_CAMERA) 即使相机不存在并且似乎是设备错误，也会返回 true。所以每当有场景需要检查设备上是否存在摄像头时，请参考下面的解决方案来了解如何处理此类故障 int numberOfCameras = Camera.getNumberOfCameras(); context = this; PackageManager pm = context.getPackageManager(); final boolean deviceHasCameraFlag = pm.hasSystemFeature(PackageManager.FEATURE_CAMERA); if( !deviceHasCameraFlag || numberOfCameras==0 ) { Log.e(TAG, "Device has no camera" + numberOfCameras); Toast.makeText(getApplicationContext(), "Device has no camera", Toast.LENGTH_SHORT).show(); captureButton.setEnabled(false); } else { Log.e(TAG, "Device has camera" + deviceHasCameraFlag + numberOfCameras); } 在此，我要检查摄像头的数量以及设备是否具有摄像头功能布尔值，因此即使系统返回一个不正确的值，另一个条件也将有助于纠正代码。就我而言，我有以下代码： public boolean hasCameraSupport() { boolean hasSupport = false; if(getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA_ANY)) { //<- this constant caused problems hasSupport = true; } return hasSupport; } 并且它在运行 Android 4.1.1 (API 16) 的 Genymotion 设备上不断返回 false。一旦我将常数 PackageManager.FEATURE_CAMERA_ANY 更改为 PackageManager.FEATURE_CAMERA，我的问题就消失了。我猜测并非所有设备/API 级别都支持PackageManager.FEATURE_CAMERA_ANY。我明白了，你一定会尝试这个，它肯定会起作用...... import android.hardware.Camera; int numCameras = Camera.getNumberOfCameras(); if (numCameras > 0) { System.out.println("camera"); } else { System.out.println("No Camera"); } 对于CameraX，如果设备上没有Camera时FEATURE_CAMERA_ANY方法仍然返回true，您可以添加以下方法。因此，当 CameraX 初始化时，无论 FEATURE_CAMERA_ANY 返回 true 还是 false，如果相机实际上在设备上不可用，下面的方法将确保执行您想要的操作。 private CameraSelector cameraSelector; private ProcessCameraProvider cameraAvailableCheck; private ListenableFuture<ProcessCameraProvider> cameraAvailableCheckFuture; private void checkIfAnyCameraExist() { cameraAvailableCheckFuture = ProcessCameraProvider.getInstance(context); cameraAvailableCheckFuture.addListener(new Runnable() { @Override public void run() { try { cameraAvailableCheck = cameraAvailableCheckFuture.get(); if ((cameraAvailableCheck.hasCamera(cameraSelector.DEFAULT_BACK_CAMERA) || cameraAvailableCheck.hasCamera(cameraSelector.DEFAULT_FRONT_CAMERA) )) { //Do what you want if at least back OR front camera exist } else { //Do what you want if any camera does not exist } } catch (ExecutionException | InterruptedException | CameraInfoUnavailableException e) { // No errors need to be handled for this Future. // This should never be reached. } } }, ContextCompat.getMainExecutor(this)); } 请尝试此代码： private boolean isDeviceSupportCamera() { if (getApplicationContext().getPackageManager().hasSystemFeature( PackageManager.FEATURE_CAMERA)) { // this device has a camera return true; } else { // no camera on this device return false; } } 还是不行请告诉我

在React语义ui列表元素中显示奇怪的字符而不是项目符号点

我正在使用react语义ui列表项目符号，但部署后项目符号点显示像奇怪的字符。我已经在 index.html 文件中包含以下代码我正在使用 React 语义 ui 列表项目符号，但部署后项目符号点显示像奇怪的字符。我已经在index.html文件中包含了以下代码 <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8" /> <link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico" /> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no" /> <meta name="theme-color" content="#000000" /> 我也有这个问题，为什么它们只是偶尔出现，并且不可选，也不属于html？

如何让div在透明背景上有纯色？

<!DOCTYPE html> <html lang="pl"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> <link rel="stylesheet" href="style.css"> </head> <body> <div id="bg"> <div id="topbar"></div> </div> </body> </html> body { background: url(bg.jpg); margin: 0; } #bg { background-color: black; margin: 0; padding: 0; height: 100vh; opacity: 0.7; } #topbar { background-color: gray; height: 80px; width: 100%; } Ive tried adding opacity: 1 to the topbar div and rgba with alpha: 1. The result: there是一个图像，其上有黑色背景，不透明度为 0.7，顶部栏的不透明度也为 0.7。我的目标是实现较暗的图像作为背景和纯色顶栏 div #topbar位于#bg内部，因此调整#bg的不透明度也会影响#topbar。我要做的是省略不透明度并将背景颜色更改为透明黑色。看起来像这样： body { background: url(bg.jpg); margin: 0; } #bg { background-color: rgba(0, 0, 0, 0.7); margin: 0; padding: 0; height: 100vh; } #topbar { background-color: gray; height: 80px; width: 100%; } 这样只有背景颜色是透明的，而不是整个元素。

从数据库中选择 SELECT 选项后如何显示/隐藏 DIV？
