首先先弄好界面xml代码

<?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="选择语言"
            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="输入需要朗读的文字"
            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="结束"
            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="循环播放"
            android:textColor="#fff"
            android:textSize="30dp"
            android:background="@drawable/loing_btns"
            android:id="@+id/btn2"/>
    </LinearLayout>

然后Mainactivity.java里面

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;
    import android.widget.AdapterView;
    import android.widget.ArrayAdapter;
    import android.widget.Button;
    import android.widget.CompoundButton;
    import android.widget.EditText;
    import android.widget.SimpleAdapter;
    import android.widget.Spinner;
    import android.widget.ToggleButton;
    
    import java.util.ArrayList;
    import java.util.List;
    import java.util.Locale;
    
    
    public class MainActivity extends AppCompatActivity {
        private TextToSpeech textToSpeech = null; //TTS
        private Spinner spinner ; //下拉列表框
        private EditText editText;
        private Button button;
        private String[] langs;//下拉列表款里面的选项
        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);
            editText = (EditText)findViewById(R.id.edt);
            button = (Button)findViewById(R.id.btn);
             Button button1 = (Button)findViewById(R.id.btn1);
            Button button2 = (Button)findViewById(R.id.btn2);
            for (int i = 0;i<langs.length;i++){
                list.add(langs[i]);
            }
            langs = getResources().getStringArray(R.array.languages);
            ArrayAdapter arrayAdapter = new ArrayAdapter(this,R.layout.support_simple_spinner_dropdown_item,langs);
            spinner.setAdapter(arrayAdapter);
            spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() { //下拉列表框点击事件
                @Override
                public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
                    curLang = (String)spinner.getAdapter().getItem((int)l);
                    if(textToSpeech!=null){
                        textToSpeech.stop();
                        textToSpeech.shutdown();
                        textToSpeech = null;
                    }
                    textToSpeech = new TextToSpeech(MainActivity.this,new TTSListener()); //给定一个TTS语音
                }
    
                @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) {
                            e.printStackTrace();
                        }
                    }
                }
            });
        }
    
        private  int SetLanguage(String lang){
            int result = 0;
            if (lang.equals("中文")){
                result = textToSpeech.setLanguage(Locale.CHINESE);
            }
            else if (lang.equals("英文")){

                    }
                }
            }
        }
    
    }

## 如果有不懂得spinner下拉列表框的使用可参考我的上一篇博客里面有详细的介绍，最后祝大家生活愉快，谢谢观看。。。    ##
