android - 将图像保存到文件android

Question

我在保存图片的问题上需要帮助。我正在使用 adobe photo sdk 来编辑我的图像。文档链接（https://creativesdk.adobe.com/docs/android/#/articles/imageediting/index.html）。他们说使用 .withOutput(Uri) 来保存我创建的图像，但得到我的图像时出错。

public class MainActivity extends AppCompatActivity {
    private static final int IMG_CODE_EDIT = 263;
    private Button mPickbtn;
    private Button mCapturebtn;
    private static int RESULT_LOAD_IMAGE = 1;
    private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 100;
    private String mCurrentPhotoPath;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mPickbtn = (Button) findViewById(R.id.pick_image);
        mCapturebtn = (Button) findViewById(R.id.button2);

        Intent cdsIntent = AdobeImageIntent.createCdsInitIntent(getBaseContext(), "CDS");
        startService(cdsIntent);

    }

    public void takePicture(View view) {
        // create Intent to take a picture and return control to the calling application
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        // start the image capture Intent
        startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
    }

    public void onClick(View view) {

        Intent i = new Intent(
                Intent.ACTION_PICK,
                android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

        startActivityForResult(i, RESULT_LOAD_IMAGE);
    }

    @Override

    @Override

        //Gets the gallery image uri
        if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
            Uri selectedImage = data.getData();
            String[] filePathColumn = {MediaStore.Images.Media.DATA};

            Cursor cursor = getContentResolver().query(selectedImage,
                    filePathColumn, null, null, null);
            cursor.moveToFirst();

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            cursor.close();

            editPic(selectedImage);
        } 

        //picture from camera
        if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
            if (resultCode == RESULT_OK) {
                Uri mPicTaken = data.getData();
                editPic(mPicTaken);
            } else if (resultCode == RESULT_CANCELED) {
                // User cancelled the image capture
            } else {
                // Image capture failed, advise user
            }
        }

                    startActivity(intent);

                    break;

Image Editor 开发人员指南目前说您应该将 a 传递Uri给withOutput()，但这是不正确的。

尝试传递一个File：

    /* 1) Change the argument to your desired location */
    File file = new File(Environment.getExternalStorageDirectory() + File.separator + "test.jpg");
    try {
        file.createNewFile();
    } catch (IOException e) {
        e.printStackTrace();
    }

    Intent imageEditorIntent = new AdobeImageIntent.Builder(this)
            .setData(imageUri)
            .withOutput(file) /* 2) Pass the File here */
            .build();

您对File构造函数的参数应该更改为您想要的任何位置。
