這是一款可以語音播報多功能的app。。。下面說說實現程式碼吧

先看一下效果圖：

首先先弄好介面xml程式碼

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent" tools:context="com.example.myapplication.MainActivity"
    android:orientation="vertical"
    android:background="@drawable/bei">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="選擇語言"
        android:textColor="#c6b821"
        android:textSize="30dp"/>
    <Spinner
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/spinner"></Spinner>
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="輸入需要朗讀的文字"
        android:textSize="30dp"
        />
    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/edt"
        android:background="@drawable/edt"
        />
    <Button
        android:layout_marginTop="10dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="播放"
        android:textColor="#fff"
        android:textSize="30dp"
        android:id="@+id/btn"
        android:background="@drawable/loing_btns"/>
    <Button
        android:layout_marginTop="10dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="結束"
        android:textColor="#fff"
        android:textSize="30dp"
        android:background="@drawable/loing_btns"
        android:id="@+id/btn1"/>
    <Button
        android:layout_marginTop="10dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="迴圈播放"
        android:textColor="#fff"
        android:textSize="30dp"
        android:background="@drawable/loing_btns"
        android:id="@+id/btn2"/>
</LinearLayout>
 

然後Mainactivity.java裡面

package com.example.myapplication;

import android.content.DialogInterface;
import android.speech.tts.TextToSpeech;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;

public class MainActivity extends AppCompatActivity {

    private Spinner spinner ; //下拉列表框
    private EditText editText;

    private String[] langs;//下拉列表款裡面的選項
    private String curLang;
    private List<String> list = new ArrayList<String>();
    private ArrayAdapter<String> arrayAdapter;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        langs = getResources().getStringArray(R.array.languages);
        spinner = (Spinner)findViewById(R.id.spinner);

        for (int i = 0;i<langs.length;i++){

        spinner.setAdapter(arrayAdapter);
        spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() { //下拉列表框點選事件
            @Override

                curLang = (String)spinner.getAdapter().getItem((int)l);
                if(textToSpeech!=null){
                    textToSpeech.stop();
                    textToSpeech.shutdown();
                    textToSpeech = null;
                }
                textToSpeech = new TextToSpeech(MainActivity.this,new TTSListener()); //給定一個TTS語音
            }

            @Override
            public void onNothingSelected(AdapterView<?> adapterView) {

            }
        });
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                textToSpeech.speak(editText.getText().toString(), TextToSpeech.QUEUE_FLUSH, null);
            }
        });
        button1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                textToSpeech.stop();
            }
        });
        button2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                for(int i = 0;i<10;i++) {
                    textToSpeech.speak(editText.getText().toString(), TextToSpeech.QUEUE_ADD, null);
                    try {
                        Thread.sleep(2000);
                    } catch (InterruptedException e) {

如果有不懂得spinner下拉列表框的使用可參考我的上一篇部落格裡面有詳細的介紹，最後祝大家生活愉快，謝謝觀看。。。
