如何在从广播接收器的活动中创建一个文本图形对象

Question

我是Android的新手。我正在尝试创建一个呼叫者名称播音员应用程序。以下是我的代码。日志显示，代码正在执行正常，即文本图形构造函数正在执行并达到OnInit方法，直到最后，当我对其进行测试时，听不到音频。

。

这是我的CustomBroadcastreceiver.java：

public class CustomBroadcastReceiver extends BroadcastReceiver {
protected String newSender;
@Override
public void onReceive(Context context, Intent intent) {
    Log.v("", "logger WE ARE INSIDE!!!!!!!!!!!");
     Intent i=new Intent(context,ReceiverActivity.class);
    TelephonyManager telephony = (TelephonyManager) context
            .getSystemService(Context.TELEPHONY_SERVICE);
    CustomPhoneStateListener customPhoneListener = new    CustomPhoneStateListener();
    telephony.listen(customPhoneListener,
            PhoneStateListener.LISTEN_CALL_STATE);
    Bundle bundle = intent.getExtras();
    String phoneNr = bundle.getString("incoming_number");
    Log.v("", "logger phoneNr: " + phoneNr);
    Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI,
            Uri.encode(phoneNr));
    Cursor cursor = context.getContentResolver().query(uri,
            new String[] { PhoneLookup.DISPLAY_NAME }, phoneNr, null, null);
    if (cursor.moveToFirst()) {
        newSender = cursor.getString(cursor
                .getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));

    }
    i.putExtra("ID", newSender);
    Log.d("","logger intent" + i.getStringExtra("ID"));
    i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(i);
    cursor.close();
}
}

这是接收者。Java

public class ReceiverActivity extends Activity implements TextToSpeech.OnInitListener{
String name;
private TextToSpeech tts;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_receiver);
    Log.d("","logger reached ReceiverActivity");
    tts = new TextToSpeech(this, this);
    Log.d("","logger created tts object");
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.receiver, menu);
    return true;
}
@Override
public void onInit(int status) {
    Log.d("","logger reached onInit");
    if (status == TextToSpeech.SUCCESS) {
        int result = tts.setLanguage(Locale.US); // java.Util.Locale for
                                                    // country codes
        if (result == TextToSpeech.LANG_MISSING_DATA
                || result == TextToSpeech.LANG_NOT_SUPPORTED) {
            Log.e("TTS", "This Language is not supported");
        } else {
            speakOut();
        }
    } else {
        Log.e("TTS", "Initilization Failed!");
    }
}
private void speakOut() {
    tts.speak(name, TextToSpeech.QUEUE_FLUSH, null);
    Log.d("","logger speak executed");
}
}

你能告诉我我要在哪里出错吗？

首先，在活动类中初始化文本对语音对象，然后用字符串参数进行静态方法，其中包含文本到语音的语法。<<<<<<<<<<<<<<<</p>

并用您要宣布的字符串从广播员中调用此静态方法。

public static void speakOut(String message) {
    System.out.println("Message is: " + message);
    tts.speak(message, TextToSpeech.QUEUE_ADD, null);
}
