Android自定义带拼音音调Textview

本文实例为大家分享了android自定义带拼音音调textview的具体代码，供大家参考，具体内容如下

1.拼音textview，简单的为把拼音数组和汉字数组结合在一起多行显示

import android.annotation.suppresslint;
import android.content.context;
import android.graphics.canvas;
import android.graphics.color;
import android.graphics.paint;
import android.text.textpaint;
import android.util.attributeset;
import android.widget.textview;
import com.cgtn.chineselearning.utils.chinesecharacter2spell;
import com.cgtn.common.utils.convertutils;

@suppresslint("appcompatcustomview")
public class spelltextview extends textview {
  private string[] pinyin;
  private string[] chinese;

  private textpaint textpaintspell = new textpaint(paint.anti_alias_flag);
  private textpaint textpaintchinese = new textpaint(paint.anti_alias_flag);

  private int fontsizespell = convertutils.dp2px(12);
  private int fontsizechinese = convertutils.dp2px(12);

  private int colorspell = color.parsecolor("#1b97d6");
  private int colorchinese = color.parsecolor("#000000");
  public spelltextview(context context) {
    super(context);
  }

  public spelltextview(context context, attributeset attrs) {
    super(context, attrs);
  }

  public spelltextview(context context, attributeset attrs, int defstyleattr) {
    super(context, attrs, defstyleattr);
    inittextpaint();
  }

  public void inittextpaint() {
    float denity = getresources().getdisplaymetrics().density;
    textpaintspell.setstrokewidth(denity);
    textpaintchinese.setstrokewidth(denity);
    textpaintspell.settextalign(paint.align.left);
    textpaintchinese.settextalign(paint.align.left);
    //设置字体大小
    textpaintspell.settextsize(fontsizespell);
    textpaintchinese.settextsize(fontsizechinese);
    textpaintspell.setcolor(colorspell);
    textpaintchinese.setcolor(colorchinese);
  }

  @override
  protected void ondraw(canvas canvas) {
    float widthmesure = 0f;
    int comlum = 1;
    float pinyinwidth;
    if (pinyin != null && pinyin.length > 0) {
      for (int index = 0; index < pinyin.length; index++) {
        pinyinwidth = widthmesure + textpaintspell.measuretext(pinyin[index]);
        if (pinyinwidth > getwidth()) {
          comlum++;
          widthmesure = 0;
        }
        canvas.drawtext(pinyin[index], widthmesure, (comlum * 2 - 1) * (textpaintchinese.getfontspacing()), textpaintspell);
        canvas.drawtext(chinese[index],
            widthmesure + (textpaintspell.measuretext(pinyin[index]) - textpaintchinese.measuretext(chinese[index])) / 2,
            (comlum * 2) * (textpaintchinese.getfontspacing()), textpaintchinese);
        if (index + 1 < pinyin.length) {
          widthmesure = widthmesure + textpaintspell.measuretext(pinyin[index] + 1);
        } else {
          widthmesure = widthmesure + textpaintspell.measuretext(pinyin[index]);
        }
      }
    }
  }

  //拼音和汉字的资源
  public void setspellandchinese(string[] pinyin, string[] chinese) {
    this.pinyin = pinyin;
    this.chinese = chinese;
  }

  //设置文字资源
  public void setstringresource(string string) {
    inittextpaint();
    string[] spellarray = chinesecharacter2spell.getpinyinstring(string);
    stringbuilder stringbuilder = new stringbuilder();
    for (string s : spellarray){
      stringbuilder.append(s);
      stringbuilder.append(" ");
    }

    char[] chars = string.tochararray();
    string[] chinesearray = new string[chars.length];
    for (int i = 0; i < chars.length;i++){
      chinesearray[i] = string.valueof(chars[i]);
    }
    setspellandchinese(spellarray,chinesearray);
  }

  //设置文字颜色
  public void setstringcolor(int spellcolor,int chinesecolor) {
    textpaintspell.setcolor(spellcolor);
    textpaintchinese.setcolor(chinesecolor);
  }

  //设置文字大小
  public void setfontsize(float spellfontsize,float chinesefontsize) {
    textpaintspell.settextsize(convertutils.dp2px(spellfontsize));
    textpaintchinese.settextsize(convertutils.dp2px(chinesefontsize));
  }
}

2.汉字转拼音使用 implementation ‘com.belerweb:pinyin4j:2.5.0'

public static string[] getpinyinstring(string character) {
  if (character != null && character.length() > 0) {
    string[] pinyin = new string[character.length()];
    hanyupinyinoutputformat format = new hanyupinyinoutputformat();
    format.setcasetype(hanyupinyincasetype.lowercase);
    format.settonetype(hanyupinyintonetype.with_tone_mark);
    format.setvchartype(hanyupinyinvchartype.with_u_unicode);
    for (int index = 0; index < character.length(); index++) {
      char c = character.charat(index);
      try {
        string[] pinyinunit = pinyinhelper.tohanyupinyinstringarray(c, format);
        if (pinyinunit == null) {
          pinyin[index] = " ";
        } else {
          pinyin[index] = pinyinunit[0];
        }
      } catch (badhanyupinyinoutputformatcombination badhanyupinyinoutputformatcombination) {
        badhanyupinyinoutputformatcombination.printstacktrace();
      }

    }
    return pinyin;
  } else {
    return null;
  }
}
