您在这里做错了,您在调用StartActivityForResult
之后添加了参数。
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, TAKE_PICTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, uriImage);
把这个换掉
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, uriImage);
startActivityForResult(intent, TAKE_PICTURE);
同时,您为图像捕获和从图库中选择图像设置了相同的请求代码,您必须设置不同的请求代码。
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == TAKE_PICTURE && resultCode== RESULT_OK){
Bitmap bitmap = (Bitmap) data.getExtras().get("data");
Intent i = new Intent(getActivity(), Upload.class);
i.putExtra("image", bitmap);
startActivity(i);
}
//TAKE_PICTURE(int 1) request code for camera capture
//PICK_PICTURE_FROM_GALLERY (int 2) code for select image from gallery.
if (requestCode == PICK_PICTURE_FROM_GALLERY && resultCode== RESULT_OK){
Bitmap bitmap = (Bitmap) data.getExtras().get("data");
Intent i = new Intent(getActivity(), Upload.class);
i.putExtra("image", bitmap);
startActivity(i);
}
}
在“开发者选项”设置中,我使用“不保留活动”模式。我需要从画廊选择图像,并在我的应用程序中使用它的URI。打开图库以选取图像的代码是: 当我选择图像时发生问题。“请等待...”显示消息,然后我返回图库中的“选择图像”。打开此模式时,HTC One X设备会发生这种情况。在三星Galaxy S3中不会出现此问题。当此模式打开时,如何在HTC ONE X设备上解决它?
用户可以从图库中捕获或选择图像。我想把那个图像上传到服务器上。 这是我的相机密码- 这是我从图库中选择图像的代码- 另外,我用下面的代码显示图像- 现在,我想把这个图像转换成base64并上传到服务器。
编辑:我调试了应用程序,并用初始化了。这消除了错误,但是现在ImageView没有得到更新,但是当我从Gallery中选择image时,它已经更新了。
我在drawable文件夹(example.jpg,sue.png)中有2个图像。 我想打开drawable文件夹作为一个库来选择一个新的图像,然后新的图像将替换原始图像(在本例中,原始图像是example.jpg) 但是当我打开图库选择新图像时,却没有图像可供选择。 我应该如何解决这个问题? 下面是我的代码: ProfileActivity: XML:
有没有一个标准的方法来调用对话框选择从相机或从图库(如内置电话簿或Skype)的图像? 我看了一下这个,但是代码打开了图库,没有建议从相机中选择它。 设备:Samsung Galaxy Tab Android:2.3.3
图库和相机在调试中正确打开(使用模拟器和真实设备),软件包请求权限(我在android清单中设置了它们),并在接受它们后打开图库。没有警告/错误。当我使用发布应用程序并在我的手机上测试它(小米redmi Note 7)时,图像选择器不会打开图库。按钮不做任何事情,应用程序也不会崩溃。我没有尝试,但我打赌它会起作用。正如我所说,我有image_picker的最新版本api 29的权限,并尝试用flu
