java中方法回調

onResult爲方法回調

RecognizeService.recGeneral(this, FileUtil.getSaveFile(getApplicationContext()).getAbsolutePath(),
        new RecognizeService.ServiceListener() {
            @Override
            public void onResult(String result) {
                infoPopText(result);
            }
        }); 

分別實現 onResult,OnError兩個方法 

OCR.getInstance(ctx).recognizeGeneral(param, new OnResultListener<GeneralResult>() {
    @Override
    public void onResult(GeneralResult result) {
        StringBuilder sb = new StringBuilder();
        for (WordSimple wordSimple : result.getWordList()) {
            Word word = (Word) wordSimple;
            sb.append(word.getWords());
            sb.append("\n");
        }
        listener.onResult(result.getJsonRes());
    }

    @Override
    public void onError(OCRError error) {
        listener.onResult(error.getMessage());
    }
});
