How to fix this problem cannot resolve method startResultActivity com.google.zxing.Result?

问题

我尝试在ResultActivity类中打开结果但为什么无法呢

我尝试从图库中的图像扫描QR码

有什么解决方案吗

以下是代码示例

// 这是扫描图像的代码
case R.id.scn_img:
    Intent pickIntent = new Intent(Intent.ACTION_PICK);
    pickIntent.setDataAndType(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "image/*");
    startActivityForResult(pickIntent, 111);
    break;

// 这是onActivityResult代码
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    switch (requestCode) {
        case 111:
            if (data == null || data.getData() == null) {
                Log.e("TAG", "The uri is null, probably the user cancelled the image selection process using the back button.");
                return;
            }
            Uri uri = data.getData();
            try {
                InputStream inputStream = getContentResolver().openInputStream(uri);
                Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
                if (bitmap == null) {
                    Log.e("TAG", "uri is not a bitmap," + uri.toString());
                    return;
                }
                // 其他图像处理逻辑...
            } catch (FileNotFoundException e) {
                Log.e("TAG", "can not open file" + uri.toString(), e);
            }
            break;
    }
}

// 这是ResultActivity类的代码
public class ResultActivity extends AppCompatActivity {
    // ... 其他代码 ...

    // 这是用来启动ResultActivity的静态方法
    public static void startResultActivity(@NonNull Context context, @NonNull BarcodeResult barcodeResult) {
        // 启动ResultActivity的逻辑...
    }

    // ... 其他代码 ...

    // 这是启动ResultActivity的示例
    ResultActivity.startResultActivity(BaseActivity.this, result);

    // ... 其他代码 ...
}

希望这个示例对你有所帮助。如有问题,请随时问我。

英文:

i try to open the result on ResultActivity class but it cant be why?

**i try to scan qr code from image from the gallery **

any solution

here is the code

case R.id.scn_img:
Intent pickIntent = new Intent(Intent.ACTION_PICK);
pickIntent.setDataAndType( android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "image/*");
startActivityForResult(pickIntent, 111);
break;

this is onActivityResult code

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
//the case is because you might be handling multiple request codes here
case 111:
if(data == null || data.getData()==null) {
Log.e("TAG", "The uri is null, probably the user cancelled the image selection process using the back button.");
return;
}
Uri uri = data.getData();
try
{
InputStream inputStream = getContentResolver().openInputStream(uri);
Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
if (bitmap == null)
{
Log.e("TAG", "uri is not a bitmap," + uri.toString());
return;
}
int width = bitmap.getWidth(), height = bitmap.getHeight();
int[] pixels = new int[width * height];
bitmap.getPixels(pixels, 0, width, 0, 0, width, height);
bitmap.recycle();
bitmap = null;
RGBLuminanceSource source = new RGBLuminanceSource(width, height, pixels);
BinaryBitmap bBitmap = new BinaryBitmap(new HybridBinarizer(source));
MultiFormatReader reader = new MultiFormatReader();
try
{
Result result = reader.decode(bBitmap);
//here i want to do the code but this not working
// here is the problem
//********************************
ResultActivity.startResultActivity(BaseActivity.this, result);
//********************************
// toast message it is work good
Toast.makeText(this, "The content of the QR image is: "
+ result.getText(), Toast.LENGTH_SHORT).show();
}
catch (NotFoundException e)
{
Log.e("TAG", "decode exception", e);
}
}
catch (FileNotFoundException e)
{
Log.e("TAG", "can not open file" + uri.toString(), e);
}
break;
}
}

here is my ResultActivity class code

public class ResultActivity extends AppCompatActivity {

break;
}
currentResultFragment = resultFragment;
resultFragment.putQRCode(parsedResult);
ft.replace(R.id.activity_result_frame_layout, resultFragment);
ft.commit();
}

}

error message it is

cannot resolve method startResultActivity com.google.zxing.Result

I want to answer with an example

Thank you

得分: 0

ResultActivity中没有名为startResultActivity的静态方法,该方法接受ContextResult作为参数

BarcodeResultResult不相同

您需要创建一个方法,其签名为public static void startResultActivity(@NonNull Context context, @NonNull Result result) {

英文:

There is no static method by the name of startResultActivity in ResultActivity that takes Context and Result as arguments

BarcodeResult is not the same as Result

You need to create a method with the signature public static void startResultActivity(@NonNull Context context, @NonNull Result result) {
