【FastDev4Android框架开发】列表头生成带文本或者字母的图片开源库TextDrawable使用和详解(二十二)

jerry Android 2015年11月26日 收藏

(一).前言:   

        今天我们主要来学习一下新的开源框架,TextDrawable。我们经常在一些应用通讯录中看到这样的效果，例如我们加了一个好友，但是该用户没有上传头像图片，那么应用要么默认显示一个默认头像，或者我们就可以自动根据姓名第一个字或者首字母自动生成一个图片。OK,TextDrawable框架(Github地址)就是可以解决这个问题。TextDrawable扩展自Drawable，用于生成文本或者字母的图片的轻量级库，可用于现有/自定义/网络等ImageView类，并且包含一个流接口用于创建drawables以及一个定制的ColorGenerator。效果如下:


       FastDev4Android框架项目地址:https://github.com/jiangqqlmj/FastDev4Android

(二).使用方法:   

       2.1.AS进行集成配置TextDrawable,使用Gradle进行导入: 


  1.        dependencies {
  2.         compile'com.amulyakhare:com.amulyakhare.textdrawable:1.0.1'
  3. }


     2.2.创建简单的标题:



  1. <ImageViewandroid:layout_width="60dp"
  2.           android:layout_height="60dp"
  3.           android:id="@+id/image_view"/>


[注].为ImageView制定了width和height，那么drawable会自动适应大小。

2.3.创建圆角



  1. TextDrawabledrawable1 = TextDrawable.builder()
  2.                 .buildRoundRect("A",Color.RED, 10); // radius in px
  3. TextDrawabledrawable2 = TextDrawable.builder()
  4.                 .buildRound("A",Color.RED);


2.4.增加圆角

   


  1. TextDrawabledrawable = TextDrawable.builder()
  2.                 .beginConfig()
  3.                     .withBorder(4) /* thicknessin px */
  4.                 .endConfig()
  5.                 .buildRoundRect("A",Color.RED, 10);


2.5.修改字体格式


  1. TextDrawabledrawable = TextDrawable.builder()
  2.                 .beginConfig()
  3.                     .textColor(Color.BLACK)
  4.                     .useFont(Typeface.DEFAULT)
  5.                     .fontSize(30) /* size in px*/
  6.                     .bold()
  7.                     .toUpperCase()
  8.                 .endConfig()
  9.                 .buildRect("a",Color.RED)


2.6.使用颜色引擎(颜色生成器)


  1. ColorGeneratorgenerator = ColorGenerator.MATERIAL; // or use DEFAULT
  2. // generate randomcolor
  3. int color1 =generator.getRandomColor();
  4. // generate colorbased on a key (same key returns the same color), useful for list/grid views
  5. int color2 =generator.getColor("user@gmail.com")
  6.  
  7. // declare thebuilder object once.
  8. TextDrawable.IBuilderbuilder = TextDrawable.builder()
  9.                 .beginConfig()
  10.                     .withBorder(4)
  11.                 .endConfig()
  12.                 .rect();
  13.  
  14. // reuse the builderspecs to create multiple drawables
  15. TextDrawable ic1 =builder.build("A", color1);
  16. TextDrawable ic2 =builder.build("B", color2);


2.7.制定宽度和高度


  1. <ImageViewandroid:layout_width="wrap_content"
  2.           android:layout_height="wrap_content"
  3.           android:id="@+id/image_view"/>


[注].这边的ImageView采用自使用width/height，可以使用编码来设置drawable的width/heigth。


  1. TextDrawabledrawable = TextDrawable.builder()
  2.                 .beginConfig()
  3.                     .width(60)  // width in px
  4.                     .height(60) // height in px
  5.                 .endConfig()
  6.                 .buildRect("A",Color.RED);
  7.  
  8. ImageView image =(ImageView) findViewById(R.id.image_view);
  9. image.setImageDrawable(drawable);


2.8.其他特点

  •  可以和其他drawables配合使用，和LayerDrawable，InsetDrawable,AnimationDrawable,TranstionDrawable等等结合使用。
  • 和其他视图兼容(不仅仅是ImageView),可以把它作为TextView，Button等等控件的背景图片。
  • 使用字母或者其他unicode字符来创建有趣的标题。

(三).使用实例:   

下面我们来具体实例：首先看一下实现的效果：


我们这边创建一个TextDrawablesTestActivity,在里面使用一个列表来分别展示11中不同的效果分别为:

  1. SAMPLE_RECT
  2. SAMPLE_ROUND_RECT
  3. SAMPLE_ROUND
  4. SAMPLE_RECT_BORDER
  5. SAMPLE_ROUND_RECT_BORDER
  6. SAMPLE_ROUND_BORDER
  7. SAMPLE_MULTIPLE_LETTERS
  8. SAMPLE_FONT
  9. SAMPLE_SIZE
  10. SAMPLE_ANIMATION
  11. SAMPLE_MISC

具体实现代码如下:


  1. packagecom.chinaztt.fda.test;
  2.  
  3. importandroid.graphics.Color;
  4. importandroid.graphics.Typeface;
  5. importandroid.graphics.drawable.AnimationDrawable;
  6. importandroid.graphics.drawable.Drawable;
  7. importandroid.os.Bundle;
  8. importandroid.view.LayoutInflater;
  9. importandroid.view.View;
  10. importandroid.view.ViewGroup;
  11. importandroid.widget.BaseAdapter;
  12. importandroid.widget.ImageView;
  13. importandroid.widget.ListView;
  14. importandroid.widget.TextView;
  15.  
  16. importcom.amulyakhare.textdrawable.TextDrawable;
  17. importcom.amulyakhare.textdrawable.util.ColorGenerator;
  18. importcom.chinaztt.fda.ui.R;

(四).源码分析:  

阅读整个该开源代码，其实实现这个效果只有两个类，ColorGenerator和TextDrawable。ColorGenerator为颜色生成引擎比较简单。

4.1.ColorGenerator.java


  1. packagecom.amulyakhare.textdrawable.util;
  2.  
  3. importjava.util.Arrays;
  4. importjava.util.List;
  5. importjava.util.Random;
  6.  
  7. /**

  11. public classColorGenerator {
  12.  
  13.     //使用默认颜色
  14.     public static ColorGenerator DEFAULT;
  15.     //使用物料模式颜色
  16.     public static ColorGenerator MATERIAL;
  17.     static {
  18.         DEFAULT = create(Arrays.asList(
  19.                 0xfff16364,
  20.                 0xfff58559,
  21.                 0xfff9a43e,
  22.                 0xffe4c62e,
  23.                 0xff67bf74,
  24.                 0xff59a2be,
  25.                 0xff2093cd,
  26.                 0xffad62a7,
  27.                 0xff805781
  28.         ));
  29.         MATERIAL = create(Arrays.asList(

  32.                 0xffba68c8,
  33.                 0xff9575cd,
  34.                 0xff7986cb,
  35.                 0xff64b5f6,
  36.                 0xff4fc3f7,
  37.                 0xff4dd0e1,
  38.                 0xff4db6ac,
  39.                 0xff81c784,
  40.                 0xffaed581,

  44.                 0xffffb74d,
  45.                 0xffa1887f,
  46.                 0xff90a4ae
  47.         ));
  48.     }
  49.  
  50.     private final List<Integer> mColors;
  51.     private final Random mRandom;
  52.  
  53.     //使用静态方法 来创建对象
  54.     public static ColorGeneratorcreate(List<Integer> colorList) {
  55.         return new ColorGenerator(colorList);
  56.     }
  57.     private ColorGenerator(List<Integer>colorList) {
  58.         mColors = colorList;
  59.         mRandom = newRandom(System.currentTimeMillis());
  60.     }
  61.  
  62.     //生成一个随机颜色
  63.     public int getRandomColor() {
  64.         returnmColors.get(mRandom.nextInt(mColors.size()));
  65.     }
  66.  
  67.     //获取具体的衍生
  68.     public int getColor(Object key) {
  69.         returnmColors.get(Math.abs(key.hashCode()) % mColors.size());
  70.     }
  71. }


4.2.TextDrawable进行构建生成相应的drawble,该采用构建者模式生成，根据我们的需求，来进行相应的构建组装即可。具体代码就不注释了，阅读起来很清晰的。

           我们的项目已经配置集成了TextDrawble的例子,大家以后在做通讯录相关的应用的时候列表中的图标根据根据姓名去设置了。同时欢迎大家去Github站点进行clone或者下载浏览:
