Question

我使用gallery从手机中选择视频和图像并将其加载到应用程序。我使用代码：

Intent photoPickerIntent = null;
if (Build.VERSION.SDK_INT < 19) {
    photoPickerIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    photoPickerIntent.setType("image/* video/*");
} else {
    photoPickerIntent = new Intent(Intent.ACTION_GET_CONTENT);
    photoPickerIntent.setType("image/* video/*");
}

一切都很好，但是当我进入内部存储/ DCIM时，我只能选择图像。视频文件是灰色的，我无法选择它们。有什么想法吗？

Answer 1

试试此代码

private static final int VIDEO_GALLERY_REQUEST = 2;
Uri video_uri;

addVideoButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent galleryIntent = new Intent(Intent.ACTION_GET_CONTENT);
            galleryIntent.setType("video/");
            startActivityForResult(galleryIntent,VIDEO_GALLERY_REQUEST);
        }
    });
 @Override
 public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode == VIDEO_GALLERY_REQUEST && resultCode == -1){
        video_uri = data.getData();

    }
}

Answer 2

启动意图：

Intent pickIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
pickIntent.setType("image/* video/*");
startActivityForResult(pickIntent, IMAGE_PICKER_SELECT);

检查视频和图片：

public void onActivityResult(int requestCode, int resultCode, Intent data) {

if (resultCode == RESULT_OK) {
    Uri selectedMediaUri = data.getData();

    if (selectedMediaUri.toString().contains("images")) {
        //Your image
    } else  if (selectedMediaUri.toString().contains("video")) {
        //Your video
    }
}

此代码解决了我的问题：

if (Build.VERSION.SDK_INT < 19) {
    Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
    intent.setType("image/* video/*");
    startActivityForResult(Intent.createChooser(intent, getResources().getString(R.string.select_picture)), SELECT_GALLERY);
} else {
    Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
    intent.addCategory(Intent.CATEGORY_OPENABLE);
    intent.setType("image/*");
    intent.putExtra(Intent.EXTRA_MIME_TYPES, new String[] {"image/*", "video/*"});
    startActivityForResult(intent, SELECT_GALLERY_KITKAT);
}

这一行：

intent.putExtra(Intent.EXTRA_MIME_TYPES, new String[] {"image/*", "video/*"});

视频无法在Android中选择
