Android实战--汉字转全拼

上一节介绍了天气预报小DEMO的制作，有些人就觉得打拼音不符合用户的习惯，怎么改成打汉字并且可以实现功能呢？这里就要用到汉字转全拼，这时我们就要引入jar包：

将jar包解压后导入我们的工程：（导入方法自行百度）

然后我们编写我们的布局文件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <EditText
        android:id="@+id/edit"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="南京" />

    <Button
        android:id="@+id/transfomer"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="转换" />

    <TextView
        android:id="@+id/show"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="" />

</LinearLayout>

编写工具类：

package com.lzg.hanzitopinyin;

import net.sourceforge.pinyin4j.PinyinHelper;
import net.sourceforge.pinyin4j.format.HanyuPinyinCaseType;
import net.sourceforge.pinyin4j.format.HanyuPinyinOutputFormat;
import net.sourceforge.pinyin4j.format.HanyuPinyinToneType;
import net.sourceforge.pinyin4j.format.HanyuPinyinVCharType;
import net.sourceforge.pinyin4j.format.exception.BadHanyuPinyinOutputFormatCombination;

public class HanZiToPinYin {
    /**
     * 返回一个字的拼音
     * @param hanzi
     * @return
     */
    public static String toPinYin(char hanzi){
        HanyuPinyinOutputFormat hanyuPinyin = new HanyuPinyinOutputFormat();
        hanyuPinyin.setCaseType(HanyuPinyinCaseType.LOWERCASE);
        hanyuPinyin.setToneType(HanyuPinyinToneType.WITHOUT_TONE);//没有声调
        hanyuPinyin.setVCharType(HanyuPinyinVCharType.WITH_U_UNICODE);
        String[] pinyinArray=null;
        try {
            //是否在汉字范围内
            if(hanzi>=0x4e00 && hanzi<=0x9fa5){
                //pinyinArray = PinyinHelper.toHanyuPinyinStringArray(hanzi, hanyuPinyin);
                pinyinArray = PinyinHelper.toHanyuPinyinStringArray(hanzi, hanyuPinyin);
            }
        } catch (BadHanyuPinyinOutputFormatCombination e) {
            e.printStackTrace();
        }
        //将汉字返回
        return pinyinArray[0];
    }
}

编写activity：

package com.lzg.hanzitopinyin;

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

public class TestActivity extends Activity {
    /** Called when the activity is first created. */
    EditText editText;
    TextView tView;
    Button trbButton;
    String pinyin;
    String hanziString;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        editText = (EditText) findViewById(R.id.edit);
        tView = (TextView) findViewById(R.id.show);
        trbButton = (Button) findViewById(R.id.transfomer);
        trbButton.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                hanziString = editText.getText().toString();
                pinyin = getPinyin(hanziString);
                tView.setText("拼音：" + pinyin + "n" + "汉字：" + hanziString);

            }
        });

    }

    private String getPinyin(String hanzi) {
        String pinyin = "";
        for (int i = 0; i < hanzi.length(); i++) {
            pinyin += HanZiToPinYin.toPinYin(hanzi.charAt(i));

        }
        return pinyin;
    }
}

运行实例如下：
