Question

我已经成功创建了一个意图选择器，其中列出了图库，文档和相机。但是当我尝试从选择器中选择相机时，点击它时没有任何反应我尝试用Camera Intent创建一个选择器，即使那时结果是一样的。

此确切代码在Marshmallow更新之前正在运行。我怀疑它与它有关。你遇到过类似的问题吗？你是怎么解决的？

以下是我创建意图选择器的代码。

public Intent getPickImageChooserIntent() {

    // Determine Uri of camera image to save.
    fileUri = getCaptureImageOutputUri();

    List<Intent> allIntents = new ArrayList<>();
    PackageManager packageManager = getPackageManager();

    // collect all camera intents
    Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
    for (ResolveInfo res : listCam) {
        Intent intent = new Intent(captureIntent);
        intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
        intent.setPackage(res.activityInfo.packageName);
        if (fileUri != null) {
            intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
        }
        allIntents.add(intent);
    }

    // collect all gallery intents
    Intent galleryIntent = new Intent(Intent.ACTION_GET_CONTENT);
    galleryIntent.setType("image/*");
    List<ResolveInfo> listGallery = packageManager.queryIntentActivities(galleryIntent, 0);
    for (ResolveInfo res : listGallery) {
        Intent intent = new Intent(galleryIntent);
        intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
        intent.setPackage(res.activityInfo.packageName);
        allIntents.add(intent);
    }

    // the main intent is the last in the list (fucking android) so pickup the useless one
    Intent mainIntent = allIntents.get(allIntents.size() - 1);
    for (Intent intent : allIntents) {
        if (intent.getComponent().getClassName().equals("com.android.documentsui.DocumentsActivity")) {
            mainIntent = intent;
            break;
        }
    }
    allIntents.remove(mainIntent);

    // Create a chooser from the main intent
    Intent chooserIntent = Intent.createChooser(mainIntent, "Select source");

    // Add all other intents
    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, allIntents.toArray(new Parcelable[allIntents.size()]));

    return chooserIntent;
}

正如@Tynn所指出的那样，问题在于新的权限模型。我必须为每个权限的权限状态设置运行时检查。

Android Intent.createChooser在点击时不会打开相机活动
