Gifts-for-designers

Introduction

一个为设计师设计的APP( ´_ゝ`)一个特别简单项目

主要用来练习Rx,当然这个适合初入Rx的看看。

自己参考的教程 给 Android 开发者的 RxJava 详解

Github地址: Gifts-for-designers 可以给个star鼓励下( ◜◡‾)っ✂╰⋃╯

Usage

( ´_ゝ`) 好像这个项目没有很多代码需要解释,不过我还是整理一份

自定义字体

//      字体  Typeface fontFace = Typeface.createFromAsset(getAssets(),  "font/Inconsolata.otf");  Typeface tvFontFace = Typeface.createFromAsset(getAssets(), "font/Lobster.ttf");  editTextHEX.setTypeface(fontFace);  editTextRGB.setTypeface(fontFace);  textView.setTypeface(tvFontFace);

Rx监听输入

RxTextView.textChanges(editTextHEX)                  .subscribeOn(AndroidSchedulers.mainThread())                  .debounce(300, TimeUnit.MICROSECONDS)                  .map(new Func1<CharSequence, String>() {                      @Override                      public String call(CharSequence charSequence) {                          return charSequence.toString();                      }                  })                  .observeOn(AndroidSchedulers.mainThread())                  .doOnNext(new Action1<String>() {                      @Override                      public void call(String s) {                          if (s.length() == 5) {                              setBackground("56abe4", 0);                              editTextRGB.setText("");                          }                          if (!colors.isEmpty()) {                              colors.clear();                              adapter.notifyDataSetChanged();                          }                        }                  })                  .filter(new Func1<String, Boolean>() {                      @Override                      public Boolean call(String s) {                          return s.length() > 5;                      }                  })                  .observeOn(AndroidSchedulers.mainThread())                  .subscribe(new Action1<String>() {                      @Override                      public void call(String s) {                            setBackground(s, 0);  //                        addColorAdapter(s);                          changeToRGB(s);                        }                      })

改变背景颜色(有个过渡效果)

    /**       * @param color       * @param mark  0:HEX 1:RGB       */   public void setBackground(String color, int mark) {          int i = 0;          ValueAnimator paramInteger;          Drawable localDrawable = this.relativeLayout.getBackground();          if ((localDrawable instanceof ColorDrawable))              i = ((ColorDrawable) localDrawable).getColor();            if (mark == 0) {              paramInteger = ValueAnimator.ofObject(new ArgbEvaluator(), i, Color                      .parseColor("#" + color));          } else {              paramInteger = ValueAnimator.ofObject(new ArgbEvaluator(), i, mark);          }              paramInteger.setDuration(500L);          paramInteger.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {                                             public void onAnimationUpdate(ValueAnimator paramAnonymousValueAnimator) {                                                 relativeLayout.setBackgroundColor((Integer)                                                         paramAnonymousValueAnimator.getAnimatedValue());                                             }                                         }            );          paramInteger.start();      }

将16进制转化成RGB

    private void changeToRGB(String s) {          int red = Integer.parseInt(String.valueOf(s.charAt(0)) + s.charAt(1), 16);          int green = Integer.parseInt(String.valueOf(s.charAt(2)) + s.charAt(3), 16);          int blue = Integer.parseInt(String.valueOf(s.charAt(4)) + s.charAt(5), 16);            Log.d(TAG, red + " " + green + " " + blue);          editTextRGB.setText("(" + red + "," + green + "," + blue + ")");        }

Todo&Issues

  • [x] 搭配色算法推荐
  • [ ] 搭配色展示(RecyclerView)
  • [ ] 目前只做了16进制颜色,RGB有些逻辑问题
  • [ ] 删除过快会有卡顿(不知道如何解决)
  • [ ] 颜色保存列表
