就像当我们想在Android应用程序中播放音频文件时,我们使用媒体播放器并从RAW文件夹中获取音频文件,我们只是播放它。我想做的就是想从字符串数据中播放音频。例子 :字符串值=" Hello Sir";
我想播放此字符串" Hello Sir"作为音频。
您可以使用TextToSpeech
:
public class MainActivity extends AppCompatActivity {
private TextToSpeech mTextToSpeech;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTextToSpeech = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
@Override
public void onInit(int status) {
if (status != TextToSpeech.ERROR) {
mTextToSpeech.setLanguage(Locale.UK);
speak("Hello sir");
}
}
});
}
private void speak(String text) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
textToSpeechGreater21(text);
} else {
textToSpeechUnder20(text);
}
}
@SuppressWarnings("deprecation")
private void textToSpeechUnder20(String text) {
HashMap<String, String> map = new HashMap<>();
map.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "MessageId");
mTextToSpeech.speak(text, TextToSpeech.QUEUE_FLUSH, map);
}
@TargetApi(Build.VERSION_CODES.LOLLIPOP)
private void textToSpeechGreater21(String text) {
String utteranceId = this.hashCode() + "";
mTextToSpeech.speak(text, TextToSpeech.QUEUE_FLUSH, null, utteranceId);
}
}
