Question

我是Android Studio新手。我想通过点击按钮用手机摄像头拍摄照片，然后显示拍摄的照片，照片将自动保存在手机图库中。我找到了一些在线示例，但我拍摄的照片未保存在图库中。我已经使用了下面的代码。我可以帮忙吗？

@Override
public void onClick(View view) {
    switch (view.getId()) {
        case R.id.buttonTakePhoto:
            Intent intent=new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(intent, CAMERA_PIC_REQUEST);
            break;
    }
} 

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == CAMERA_PIC_REQUEST) {
        Bitmap image = (Bitmap) data.getExtras().get("data");
        ImageView imageview = (ImageView) findViewById(R.id.imageView);
        imageview.setImageBitmap(image);
    }
}

要使用相机意图拍摄图像并将其存储在图库中使用此功能，您将获得onActivityResult

的结果

    private void takeImageFromCamera() {
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
        File exportDir = new File(Environment.getExternalStorageDirectory(), "TempFolder");
        if (!exportDir.exists()) {
            exportDir.mkdirs();
        } else {
            exportDir.delete();
        }
        File mTempCameraPhotoFile = new File(exportDir, "/" + UUID.randomUUID().toString().replaceAll("-", "") + ".jpg");
        Log.d("TAG", "/" + UUID.randomUUID().toString().replaceAll("-", "") + ".jpg");
        takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(mTempCameraPhotoFile));


        startActivityForResult(takePictureIntent, Config.CAMERA_PIC_REQUEST);

    }
}
