问题描述
我正在开发一个使用呼叫者姓名的应用程序。问题是我无法在后台启动TTS。也许您可以建议一种更正确的方法来编写此程序，但是现在我创建了2个服务，启动第一个服务后，接收器在后台工作，第二个服务应发出呼叫者的名字。但是我得到了错误：

MainActivity：
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
check_permissions();
}
private void check_permissions() {
if (ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_CALL_LOG) != PackageManager.PERMISSION_GRANTED || ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.SYstem_ALERT_WINDOW) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(MainActivity.this,new String[]{Manifest.permission.READ_CALL_LOG,Manifest.permission.READ_PHONE_STATE,Manifest.permission.READ_CONTACTS,Manifest.permission.FOREGROUND_SERVICE},1);
}
}
@Override
protected void onPostResume() {
super.onPostResume();
}
@Override
protected void onPause() {
super.onPause();
}
public void start_service(View view) {
getApplicationContext().startService(new Intent(this,myService.class));
}
public void stop_service(View view) {
getApplicationContext().stopService(new Intent(this,myService.class));
}
}
背景服务：
public class myService extends android.app.Service {
@Override
public void onCreate() {
Log.d("my_TAG","onCreate");
super.onCreate();
}
@Override
public int onStartCommand(Intent intent,int flags,int startId) {
Log.d("my_TAG","onStartCommand");
return START_STICKY;
}
@Override
public void onDestroy() {
Log.d("my_TAG","onDestroy");
}
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
}
语音服务文字：
public class TTS extends Service implements TextToSpeech.OnInitListener {
private TextToSpeech tts;
private String spokenText;
private boolean isLoaded;
@Override
public void onCreate() {
super.onCreate();
Log.d("my_TAG","onCreate");
tts = new TextToSpeech(this,this);
}
@Override
public int onStartCommand(Intent intent,"onStartCommand");
spokenText = intent.getStringExtra("name");
return START_NOT_STICKY;
}
private void speak() {
if (tts != null && isLoaded){
tts.speak(spokenText,TextToSpeech.QUEUE_FLUSH,null,"1");
}
}
@Override
public void onInit(int status) {
Log.d("my_TAG","onInit entered " + status);
if (status == TextToSpeech.SUCCESS) {
int result = tts.setLanguage(new Locale("en"));
if (result != TextToSpeech.LANG_MISSING_DATA && result != TextToSpeech.LANG_NOT_SUPPORTED) {
Log.d("my_TAG","isLoaded = true;");
isLoaded = true;
speak();
} else {
Log.d("my_TAG","Language has missing data or is not supported");
}
} else {
Log.d("my_TAG","Status unsuccessful");
}
}
@Override
public void onDestroy() {
super.onDestroy();
if (tts != null) {
tts.stop();
tts.shutdown();
}
Log.d("my_TAG","onDestroy");
}
@Override
public IBinder onBind(Intent arg0) {
return null;
}
}
在接收器中：
private void onIncomingCallAnswered(Context ctx,String number,Date start) {
if (number != null) {
Log.e("my_TAG",number + "answered");
intent = new Intent("stop_voice");
intent.putExtra(IS_ENDED_TAG,true);
ctx.sendbroadcast(intent);
}
}
;
private void find_name(String number,Context context) {
ContentResolver contentResolver = context.getContentResolver();
Uri uri = Uri.withAppendedpath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI,Uri.encode(number));
Cursor cursor = contentResolver.query(uri,new String[]{ContactsContract.PhoneLookup.disPLAY_NAME},null);
if (cursor == null) {
return;
}
if (cursor.movetoFirst()) {
contact_name = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.disPLAY_NAME));
} else {
contact_name = "UnkNown contact";
}
if (!cursor.isClosed()) {
cursor.close();
}
}
