- 我开发了应用程序，其中有4个声音文件一起播放
- 第一声 ：
- 按下下一步按钮-第二声音 ：
- 在上一个按钮按下时
- 第三声 ：
- 播放项目的声音
-
第四种声音：
- 在项目上播放（项目如何说话）
-
一切正常，直到用户播放和第四个快速的文本到语音引擎崩溃
媒体播放器： 错误 （-19， 0） 安卓
- 我尝试重置媒体播放器，在下一个和上一个按钮中释放并停止，但在几次来回和第四次后仍然停止了项目的声音。
我做了什么：
public class A extends Activity {
int imgArr[] = {R.drawable.a, R.drawable.b, R.drawable.c, R.drawable.d};
int soundsrc[] = {R.raw.a, R.raw.b, R.raw.c, R.raw.d};
String pro[] = new String[]{"a", "b", "c", "d"};
ImageView iView;
int count = 0;
TextToSpeech txtToSpeech1;
MediaPlayer mp;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_names);
stopService(new Intent(this, PlayMusic.class));
iView = (ImageView) findViewById(R.id.imageView5);
iView.setImageResource(R.drawable.befora);
txtToSpeech1 = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
@Override
public void onInit(int status) {
if(status != TextToSpeech.ERROR) {
txtToSpeech1.setLanguage(Locale.UK);
txtToSpeech1.speak(pro[count], TextToSpeech.QUEUE_FLUSH, null);
}
}
});
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
aSounds();
}
}, 1000);
}
@Override
public void onDestroy() {
// Don't forget to shutdown!
if (txtToSpeech1 != null) {
txtToSpeech1.stop();
txtToSpeech1.shutdown();
}
super.onDestroy();
}
public void onPause(){
if(txtToSpeech1 !=null){
txtToSpeech1.stop();
txtToSpeech1.shutdown();
}
super.onPause();
}
public void aSounds() {
mp = MediaPlayer.create(ANames.this, soundsrc[count]);
mp.start();
}
public void forwardd(View v) {
buttonSounds(R.raw.multimedia_button_click);
if (count < imgArr.length && count >= 0) {
count++;
if (count == imgArr.length)
count = 0;
iView.setImageResource(imgArr[count]);
if (txtToSpeech1.isSpeaking()) {
Log.i("Tag", "Stop speaking");
txtToSpeech1.stop();
}
txtToSpeech1.speak(pro[count], TextToSpeech.QUEUE_FLUSH, null);
// Execute some code after 2 seconds have passed
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
aSounds();
}
}, 1000);
}
}
public void backwardd(View v) {
buttonSounds(R.raw.multimedia_button_click);
if (count >= 0 && count < imgArr.length) {
count--;
if (count == -1) {
count = imgArr.length - 1;
}
iView.setImageResource(imgArr[count]);
txtToSpeech1.speak(pro[count], TextToSpeech.QUEUE_FLUSH, null);
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
aSounds();
}
}, 1000);
}
}
public void onImageClick(View v) {
txtToSpeech1.speak(pro[count], TextToSpeech.QUEUE_FLUSH, null);
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
aSounds();
}
}, 1000);
}
public void home(View v) {
buttonSounds(R.raw.multimedia_button_click);
Intent ii = new Intent(ANames.this, PlayMusic.class);
finish();
startService(ii);
}
public void buttonSounds(int src) {
mp = MediaPlayer.create(ANames.this, R.raw.multimedia_button_click);
mp.start();
}
}
-- 我已经尝试了很长时间
- 尝试了几乎所有关于媒体播放器工作的堆栈溢出答案。
- 还有如何在单击按钮时停止，释放，重置，启动媒体播放器，但对我没有任何用处。
--所以最后决定把问题放在堆积如山的堆里寻求帮助
-- 任何帮助都非常欢迎，提前感谢
如果按钮播放声音效果，如 1-4 秒。考虑使用 SoundPool 类。据我所知，它应该用于那些东西。媒体播放器错误链接和链接。似乎无论谁收到错误 19，都需要释放他正在播放的资源。
