1. EditText 에 포커스 주기

SearchInput = (RelativeLayout) findViewById(R.id.SearchInput);

SearchInput.setVisibility(View.VISIBLE);

SearchInput.requestFocus();

2. 현재 포커스 위치한곳에 소프트 키보드 띄우기

1) 키보드 사용 표시

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);

imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);

2) 키보드 사용을 숨기기

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);

imm.hideSoftInputFromWindow(view.getWindowToken(),0);

In this tutorial we are going to show how to use Android’s Speech To Text API. Android currently supports offline mode also. The only thing is that you have to downlad offline language packages.

To learn how to enable offline mode speech to text, please follow the tutorial How to enable offline Speech To Text in Android

See following Steps :

1. Start RecognizerIntent intent with the RecognizerIntent.ACTION_RECOGNIZE_SPEECH as action.
2. Handle the text data returned by Speech to Text API

1. Manifest file

2. Activity layout file

3. Main Activity code

Start the speech recognizer intent using startActivityForResult() with bundle extras.

Required extras:

• EXTRA_LANGUAGE_MODEL

Optional extras:

• EXTRA_PROMPT
• EXTRA_LANGUAGE
• EXTRA_MAX_RESULTS
• EXTRA_RESULTS_PENDINGINTENT
• EXTRA_RESULTS_PENDINGINTENT_BUNDLE

Result extras (returned in the result, not to be specified in the request):

• EXTRA_RESULTS

Note: The extra EXTRA_LANGUAGE_MODEL is mandatory. Also handle ActivityNotFoundException there may be no applications installed in the device to support this speech recognition action.

4. Demonstration
Speech to text demonstration using RecognizerIntent .

Offline mode is not enabled

아래 내용은 안드로이드 6.x 까지만 적용되는 예제입니다.

안드로이드 7.x 부터는 다른 예제를 찾아보세요! ㅜ.ㅜ

참고 : http://duongame.tistory.com/263 (Android 7.0 APK 파일 설치)

웹서버 설정

1. 파일명 : application.properties

message 에서 줄바꿈 하려면 한줄로 적되, 개행할 곳에 \r\n 를 사용하면 된다.

2. 원문파일명 : application.properties.source.txt

기존에 설치된 app 의 AndroidManifest.xml 과 웹서버에 있는 application.properties 의 versionCode 를 비교해서

웹서버 versionCode 값이 더 클 경우 앱에서 팝업으로 알려주게 된다. (최대값이 

2147483647

 이다.)

versionName 은 필요시 사용자에게 보여주기 위한 번호일 뿐이다. (비교 안함)

AndroidManifest.xml 파일의 옵션값이 먹히지 않을 경우 (AndroidStudio를 사용할 경우) build.gradle (Module: app) 내의 옵션이 우선되기 때문이다.

3. 파일 형식 변환

원문 파일을 jdk 폴더 내의 bin폴더에 있는 native2ascii.exe 명령으로 바꾼것이다.

native2ascii.exe application.properties.source.txt application.properties

[사용 방법]

-- versionCode 와 앱의 manifest 파일의 versionCode와 일치시키면 된다. versionName도 마찬가지로 일치시키면 된다.

-- fileName은 앱의 파일 이름을 적어주면된다.

-- message에는 업데이트 된 내용을 적어주면 된다.

-- title은 다운로드 받는 progress dialog의 제목이다.

설정 파일 작성을 완료 했다면 설정 파일과 앱파일을 서버상에 같은 폴더에 업로드 한다.

아래 소스에서는 웹서버의 /download/ 디렉토리에 업로드 하도록 하였다.

           sb.append(str);

        }

        display.setText(sb.toString());

    } catch (IOException e) {

        e.printStackTrace();

    }

        android:layout_width="match_parent"

        android:layout_height="wrap_content" />

        public void run() {

            final ImageView imgNumber = (ImageView) findViewById(R.id.getImage);

            imgNumber.setVisibility(View.GONE);

        }

    };

    Handler myHandler = new Handler();

나중에 클릭리스너나 키이벤트에 아래 내용 추가해서 불러오면 됩니다.

    myHandler.removeCallbacks(myRunnable);       // 반복해서 누를경우 기존 딜레이 취소

    myHandler.postDelayed(myRunnable, 5000);    // 딜레이 호출 (5초뒤 실행)

혹시 안될경우 {, } 밖으로 또는 안으로 이동하며 테스트 해볼것. 위치가 중요합니다.
