CalendarView
组件来展示日期,并结合数据库或SharedPreferences记录用户的签到状态。用户点击特定日期时,检查是否已签到,未签则标记为已签,并更新UI显示。SpeechRecognizer
类。以下是一个简单的示例代码:,,``java,import android.content.Intent;,import android.os.Bundle;,import android.speech.RecognitionListener;,import android.speech.RecognizerIntent;,import android.speech.SpeechRecognizer;,import androidx.appcompat.app.AppCompatActivity;,import java.util.ArrayList;,,public class MainActivity extends AppCompatActivity {, private SpeechRecognizer speechRecognizer;,, @Override, protected void onCreate(Bundle savedInstanceState) {, super.onCreate(savedInstanceState);, setContentView(R.layout.activity_main);,, speechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);, speechRecognizer.setRecognitionListener(new RecognitionListener() {, @Override, public void onReadyForSpeech(Bundle params) {},, @Override, public void onBeginningOfSpeech() {},, @Override, public void onRmsChanged(float rmsdB) {},, @Override, public void onBufferReceived(byte[] buffer) {},, @Override, public void onEndOfSpeech() {},, @Override, public void onError(int error) {},, @Override, public void onResults(Bundle results) {, ArrayList matches = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);, if (matches != null && !matches.isEmpty()) {, String recognizedText = matches.get(0);, // 处理识别结果, }, },, @Override, public void onPartialResults(Bundle partialResults) {},, @Override, public void onEvent(int eventType, Bundle params) {}, });,, Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);, intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);, intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1);, speechRecognizer.startListening(intent);, },, @Override, protected void onDestroy() {, super.onDestroy();, if (speechRecognizer != null) {, speechRecognizer.destroy();, }, },},
`,,这段代码创建了一个
SpeechRecognizer实例,并设置了一个
RecognitionListener来处理语音识别的结果。通过调用
startListening`方法启动语音识别,并在识别完成后处理结果。org.json
库,通过JSONObject
和JSONArray
类解析JSON格式的数据,并使用toString()
方法将数据转换为JSON格式。AudioRecord
类来捕获音频数据,并通过AudioTrack
类播放。Powered By Z-BlogPHP 1.7.3
