在我的文本到语音风格的应用程序中我可以设置语音的速度和音高，还有2个变量用于超声波音高设置。如果我设置速度和音高并退出设置菜单一切都很好，问题是如果我按下完成按钮并且频率分析仪运行并设置超声波变量，变量会在偏好编辑器中保存在错误的位置，从而导致在超声值设置的速度和音高，我已经尝试了2天来修复它但没有任何作用，下面是相关的代码，如果你需要更多请问，谁能看到我做错了什么？ / p> 编辑：这是一个apk显示问题，转到设置菜单（从工具栏右上角）设置速度和音高，按完成，关闭应用程序，打开应用程序，转到设置，你会看到荒谬的值设置为速度和音调 Canine Remote apk

此按钮在首选项编辑器中设置音高

editor.putFloat(MYPITCH, pitch);

此按钮在首选项编辑器中设置速度，如果需要查看，我还在此处包含滑块和复选框代码

editor2.putFloat(MYSPEED, speed);
editor2.commit();
tts.setSpeechRate(speed);
}
});
//slider bars to get pitch and speed
cpitch.setProgress(1);
edit.setText("Adjust voice Pitch: " + cpitch.getProgress());
cpitch.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
Globals g = (Globals) getApplication();
@Override
public void onProgressChanged(SeekBar cpitch, int progresValue, boolean fromUser) {

}
@Override
public void onStartTrackingTouch(SeekBar cspeed) {
}
@Override
public void onStopTrackingTouch(SeekBar cspeed) {
edit2.setText("Adjust voice speed: " + progress2);
g.setData3(progress2);
}
});
}
//check boxes
class clicker implements CheckBox.OnCheckedChangeListener {
public void onCheckedChanged(CompoundButton buttonView,

SharedPreferences.Editor editor5 = appPreferences.edit();
if (isChecked) {
if (buttonView == ckultra) {
editor5.putInt(HUMANDOGCAT, 1).commit();
ckultra2.setChecked(false);
}
if (buttonView == ckultra2) {
editor5.putInt(HUMANDOGCAT, 2).commit();
ckultra.setChecked(false);
}
if (buttonView == cklocal) {
editor5.putInt(REMOTE, 1).commit();
}
}
if (!isChecked) {
if (buttonView == ckultra) {
editor5.putInt(HUMANDOGCAT, 0).commit();
}
if (buttonView == ckultra2) {
editor5.putInt(HUMANDOGCAT, 0).commit();
}
if (buttonView == cklocal) {

}
此按钮是导致错误的代码的开头
edit6.setOnClickListener(new View.OnClickListener() {

}
});
//analyze pitch to set ultrasound variables
public void Spectrometer_Start() {
try {
Nb = AudioRecord.getMinBufferSize(freq, AudioFormat.CHANNEL_IN_MONO, AudioFormat.ENCODING_PCM_16BIT) * 4;
N = Nb * Byte.SIZE / Short.SIZE;

mAudioRecord.startRecording();
running=1;
analizer();
} catch (IllegalArgumentException i) {
}
}
此方法将偏好设置保存在首选项编辑器中的错误位置
public void analizer() {
int a=10;
while(tts.isSpeaking())
{
a-=1;
if(a==0)
{
short[] data= new short[muestras];
try {
mAudioRecord.read(data, 0, muestras-1);
Dft(data);
} catch (Exception e) {
e.printStackTrace();
}
a=10;
}
}
mAudioRecord.stop();
mAudioRecord.release();
Globals g = (Globals) getApplication();
running=0;
mean=((freakMax-freakMin)*0.5)+freakMin;
float calcDog = (float) (22000 / mean);
float calcCat = (float) (48000 / mean);
g.setData4(calcDog);
g.setData5(calcCat);
SharedPreferences.Editor editor7 = appPreferences.edit();
editor7.putFloat(ULTRADOG, calcDog);
editor7.putFloat(ULTRACAT, calcCat);
editor7.commit();
}
public void Dft(short[] inreal) {
for (int k = indMin; k < indMax; k++)
{
float sumreal = 0;
float sumimag = 0;
float PI2kn= (float) (PI2n * k);
for (int t = 0; t < muestras; t++) {
double angle = t*PI2kn;
sumreal += inreal[t] * Math.cos(angle);
sumimag += inreal[t] * Math.sin(angle);
}
newFrequency = (Math.sqrt(sumreal * sumreal + sumimag * sumimag));
if (newFrequency < freakMin && newFrequency >= 85) {
freakMin = newFrequency;
}
if (newFrequency > freakMax && newFrequency <= 255) {
freakMax = newFrequency;
}
}
}
此按钮启动输入的语音，并从首选项编辑器接收错误的值
edit9.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String sendComands= edit7.getText().toString();
if (!sendComands.equals("") && settingLanguage == 0){

float NSPEED = appPreferences.getFloat(MYSPEED, (float) 1.0);
float UDOG = appPreferences.getFloat(ULTRADOG, (float) 1.0);
float UCAT = appPreferences.getFloat(ULTRACAT, (float) 1.0);
int HDC = appPreferences.getInt(HUMANDOGCAT, 0);
switch (HDC) {
case 0:
tts.setPitch(NPITCH);
break;
case 1:
tts.setPitch(UDOG);
break;
case 2:
tts.setPitch(UCAT);
break;
}
tts.setSpeechRate(NSPEED);
speakIT(sendComands);
edit7.setHint("Enter text to send");
settingUp=false;
}
if (settingLanguage == 1) {
countryC(sendComands);
settingLanguage=0;
edit7.setHint("Enter text to send");
edit9.setText("Send");
edit7.setVisibility(View.GONE);
edit9.setVisibility(View.GONE);
}
}
});
工具栏中的我的设置菜单带有注释，以便您知道哪些对象执行了哪些操作

答案 0 :(得分：2)
您使用无效密钥将值存储在sharedPreferences中：
这些值用作键：
private static final String MYPITCH = "1.0";
private static final String MYSPEED = "1.0";
private static final String ULTRADOG = "1.0";
private static final String ULTRACAT = "1.0";
此处存储值
editor.putFloat(MYPITCH, pitch);
editor2.putFloat(MYSPEED, speed);
editor7.putFloat(ULTRADOG, calcDog);
editor7.putFloat(ULTRACAT, calcCat);
此处获取值
float NPITCH = appPreferences.getFloat(MYPITCH, (float) 1.0);
float NSPEED = appPreferences.getFloat(MYSPEED, (float) 1.0);
float UDOG = appPreferences.getFloat(ULTRADOG, (float) 1.0);
float UCAT = appPreferences.getFloat(ULTRACAT, (float) 1.0);
您应该使用唯一和有意义的密钥：
private static final String MYPITCH = "my_pitch";
private static final String MYSPEED = "my_speed";
private static final String ULTRADOG = "ultra_dog";
private static final String ULTRACAT = "ultra_cat";
