Android 开发汉字转带声调的拼音

复制代码

一、引入：
implementation("com.github.stuxuhai:jpinyin:1.1.7")

二、布局

复制代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center_horizontal"
    android:orientation="vertical"
    android:padding="16dp">
    <TextView
        android:id="@+id/textViewPinyin"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:background="@drawable/edittext_background" />

    <EditText
        android:id="@+id/editTextPinyin"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="请输入文字" />
    <Button
        android:id="@+id/btnSpeak"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="20dp"
        android:text="朗读" />

</LinearLayout>

三、java 代码
