你可以让一个完整的图像以实际的方式着色，当你用某种颜色填充某个区域时，它将替换该颜色指定的所有区域待填写.

You can have a complete image colored the actual way and when you fill a certain region with a color, it will replace all the regions that is specified by that color to be filled in.

外行条款:

1. 用户将点击大纲的手
2. 该点击位置将与另一张具有完美颜色编码区域的图像进行检查.对于这种情况，让我们称其为 MASK.所有皮肤区域都将具有相同的颜色.衬衫区域将是另一种颜色.
3. 无论用户点击何处，用户选择的颜色都会应用于 MASK 中具有相似颜色的每个像素，但不是直接在 MASK 上绘制，而是绘制到 OUTLINE 的像素上.

我希望这会有所帮助.

如果你想要一个例子，请随时发表评论，然后我可以用它更新答案，但我认为你可以从这里得到它.

Feel free to comment if you want an example and then I can update the answer with that, but I think you can get it from here.

基本上从像这样的简单图像开始.这我们可以称之为OUTLINE

Basically start off with a simple image like this. This we can call as OUTLINE

那么作为开发人员，您必须做一些工作.在这里，您可以对大纲进行颜色编码.我们将结果称为 MASK.为此，我们使用您想要的相同颜色对区域进行颜色编码.这可以在油漆或其他任何东西上完成.我用 Photoshop 很酷 :D.

Then as the developer, you have to do some work. Here, you color code the OUTLINE. The result we call a MASK. To make this we, color code the regions with the same color that you want. This can be done on paint or whatever. I used Photoshop to be cool lol :D.

然后是算法让它在手机上工作.在阅读代码之前，先看看这个变量.

Then there is the ALGORITHM to get it working on the phone. Before you read the code, look at this variable.

int ANTILAISING_TOLERANCE = 70; //Larger better coloring, reduced sensing

如果您放大图像，特别注意边框的黑色区域，您实际上可以看到，有时计算机会稍微混合颜色.为了说明这种变化，我们使用了这个容差值.

If you zoom up on the image specifically noting the black regions of the border, you can actually see that sometimes, the computer blends the colors a little bit. In order to account for that change, we use this tolerance value.

COLORINGANDROIDACTIVITY.JAVA

package mk.coloring;

import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.Bitmap.Config;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.widget.ImageView;
import android.view.View.OnTouchListener;

public class ColoringAndroidActivity extends Activity implements OnTouchListener{
    /** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    findViewById(R.id.imageView1).setOnTouchListener(this);
}

int ANTILAISING_TOLERANCE = 70;
public boolean onTouch(View arg0, MotionEvent arg1) {
    Bitmap mask = BitmapFactory.decodeResource(getResources(), R.drawable.mask);
    int selectedColor = mask.getPixel((int)arg1.getX(),(int)arg1.getY());           
    int sG = (selectedColor & 0x0000FF00) >> 8;
    int sR = (selectedColor & 0x00FF0000) >> 16;
    int sB = (selectedColor & 0x000000FF);

    Bitmap original = BitmapFactory.decodeResource(getResources(), R.drawable.empty);       
    Bitmap colored = Bitmap.createBitmap(mask.getWidth(), mask.getHeight(), Config.ARGB_8888);
    Canvas cv = new Canvas(colored);
    cv.drawBitmap(original, 0,0, null);

    for(int x = 0; x<mask.getWidth();x++){
        for(int y = 0; y<mask.getHeight();y++){
            int g = (mask.getPixel(x,y) & 0x0000FF00) >> 8;
            int r = (mask.getPixel(x,y) & 0x00FF0000) >> 16;
            int b = (mask.getPixel(x,y) & 0x000000FF);
            if(Math.abs(sR - r) < ANTILAISING_TOLERANCE && Math.abs(sG - g) < ANTILAISING_TOLERANCE && Math.abs(sB - b) < ANTILAISING_TOLERANCE)
                colored.setPixel(x, y, (colored.getPixel(x, y) & 0xFF000000) | 0x00458414);
        }
    }
    ((ImageView)findViewById(R.id.imageView1)).setImageBitmap(colored);

    return true;
}

}

这段代码没有为用户提供很多颜色选择.相反，如果用户触摸某个区域，它会查看MASK 并相应地绘制大纲.但是，您可以制作非常有趣和互动的作品.

This code doesn't provide the user with much of color choices. Instead, if the user touches a region, it will look at the MASK and paint the OUTLINE accordingly. But, you can make really interesting and interactive.

结果

当我摸到那个男人的头发时，它不仅染了头发，还把他的衬衫和手染成了同样的颜色.将其与 MASK 进行比较，以了解发生的情况.

When I touched the man's hair, it not only colored the hair, but colored his shirt and hand with the same color. Compare it with the MASK to get a good idea of what happened.

这只是一个基本的想法.我创建了多个位图，但实际上并不需要.我将它用于测试目的并占用了不必要的内存.而且您不需要在每次点击时重新创建蒙版，等等.

This is just a basic idea. I have created multiple Bitmaps but there is not really a need for that. I had used it for testing purposes and takes up unnecessary memory. And you don't need to recreate the mask on every click, etc.

希望对你有帮助:D

祝你好运
