Android的 - 斯普利特绘制对象 [英] Android - Split Drawable

问题描述

我试图将图像分割成块，可以说，例如16块（4×4）。

I am attempting to split an image into pieces, lets say for example 16 chunks (4x4).

我发现这样的例子很多用java，而Android不具备的BufferedImage并没有什么......我想。

I have found so many examples with java, but Android does not have BufferedImage and what not... I think.

我对如何一个体面的想法，但我真的不知道从哪里开始。

I have a decent IDEA on how to, but I don't really know where to start.

我应该使用位图或绘制？

Should I use a bitmap or a drawable?

有没有一种方法来拆分或我将不得不做出一个自定义的方法？

Is there a method to split or will I have to make a custom method?

我应该使用一个GridView保持分离像？

Should I use a GridView to hold the split images?

我不希望传达给COM的newbish并希望有人帮我这个忙，我希望做我自己满意的，但我没有得多一个想法从哪里开始，因为我是新以图形的Java和Android。

I don't want to com across as newbish and wanting to have someone do this for me, I want the satisfaction of doing it myself, but I don't have to much of an idea where to start since I am new to graphics in Java and Android.

希望我的大部分问题都回答的，甚至有例子可我找不到某种原因。

Hopefully most of my questions are answerable and maybe even have examples available that I can't find for some reason.

推荐答案

我觉得你需要这个

void createImageArrays()
{
    Bitmap bMap = BitmapFactory.decodeResource(getResources(), image);
    Bitmap bMapScaled = Bitmap.createScaledBitmap(bMap, 240, 240, true);

    bitmapsArray[0] = Bitmap.createBitmap(bMapScaled, 0, 0, 80, 80);
    bitmapsArray[1] = Bitmap.createBitmap(bMapScaled, 80, 0, 80, 80);
    bitmapsArray[2] = Bitmap.createBitmap(bMapScaled, 160, 0, 80, 80);
    bitmapsArray[3] = Bitmap.createBitmap(bMapScaled, 0, 80, 80, 80);
    bitmapsArray[4] = Bitmap.createBitmap(bMapScaled, 80, 80, 80, 80);
    bitmapsArray[5] = Bitmap.createBitmap(bMapScaled, 160, 80, 80, 80);
    bitmapsArray[6] = Bitmap.createBitmap(bMapScaled, 0, 160, 80, 80);
    bitmapsArray[7] = Bitmap.createBitmap(bMapScaled, 80, 160, 80, 80);
    bitmapsArray[8] = Bitmap.createBitmap(bMapScaled, 160, 160, 80, 80);

}

原始图像是240x240，我把它分成9个80×80的

The original image is 240x240 and I divided it into 9 pieces of 80x80
