1-dars. Android ilovalari haqida ikkita asosiy tushuncha

shutdown(): Ushbu metod TextToSpeech foydalanadigan resurslarni yopadi.

stop(): bu metod gapirishni to'xtatadi.

Endi Android Studio-da ishlashni boshlaylik. Hozir yaratadigan ilovamizda TextToSpeech sinfidan foydalanishni o'rganib olamiz. Ilovamizda matn kiritish uchun EditText-dan foydalanamiz. Matnni kiritgandan so'ng matnni ovozga aylantirish uchun tugma qo'shamiz. Demak, boshladik.
Android Studio-da yangi ilova yarating. activity_main.xml faylini quyidagicha o'zgartiring:

xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="8dp"
android:transitionGroup="true"
tools:context=".MainActivity">


android:id="@+id/editText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentStart="true"
android:layout_alignParentLeft="true"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_marginTop="46dp"
android:textColor="#2f7fff" />


android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/editText"
android:layout_centerHorizontal="true"
android:layout_marginTop="46dp"
android:text="Tinglash" />



Endi TextToSpeech kodini qo'shish uchun MainActivity.java faylini o'zgartiring:
package com.example.android.texttospeech;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;

import android.speech.tts.TextToSpeech;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

import java.util.Locale;

public class MainActivity extends AppCompatActivity {

TextToSpeech t1;

EditText ed1;
Button b1;

@Override

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ed1 = findViewById(R.id.editText);
b1 = findViewById(R.id.button);

t1 = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {

@Override
public void onInit(int status) {
if (status != TextToSpeech.ERROR) {
t1.setLanguage(Locale.ENGLISH);
}
}
});

b1.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
String toSpeak = ed1.getText().toString();
Toast.makeText(getApplicationContext(), toSpeak, Toast.LENGTH_SHORT).show();
t1.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null);
}
});
}

public void onPause() {

if (t1 != null) {
t1.stop();
t1.shutdown();
}
super.onPause();
}
}
Bu kodda yuqorida aytilgan metodlardan foydalanilgan.
Endi ilovani ishga tushiring:

Endi matn maydoniga bir nechta so'z yoki matnni kiriting va "TINGLASH" tugmasini bosing. Kiritilgan matnni ko'rsatuvchi xabar chiqadi va siz matn(so'z)ni inglizcha talaffuzini eshitishingiz mumkin. Chunki biz java kodida setLanguage(Locale.ENGLISH) qilib ingliz tilini tanlagandik. Siz o'zingiz boshqa tilni tanlashingiz mumkin:

Sizlarga ulashmoqchi bo'lgan ma’lumotlarim shulardan iborat edi. Sizlarga foydali bo’ldi degan, umiddaman. Ko'proq ma'lumot olish uchun:
