Android如何在同一时间从相机或图库中挑选图片

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

Intent pickPhotoIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

startActivityForResult(intent, requestCode);

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        if (requestCode == REQUEST_CAMERA) {
            // 从相机返回的结果
            Bitmap photo = (Bitmap) data.getExtras().get("data");
            // 处理图片
        } else if (requestCode == REQUEST_GALLERY) {
            // 从图库返回的结果
            Uri selectedImage = data.getData();
            // 处理图片
        }
    }
}
