如何编程创建简单的形象？

问题描述

我要在我的应用程序编程方式创建简单的图像。简单的形象是黑色背景，这是编程创建的文本。可能吗？谢谢。

解决方案

  INT宽度= 200;
    INT高= 100;
    点阵位图= Bitmap.createBitmap（宽度，高度，Config.ARGB_8888）;
    帆布油画=新的Canvas（位）;

    涂料粉刷=新的油漆（）;
    paint.setColor（Color.BLACK）;
    paint.setStyle（Paint.Style.FILL）;
    canvas.drawPaint（油漆）;

    paint.setColor（Color.WHITE）;
    paint.setAntiAlias​​（真正的）;
    paint.setTextSize（14.f）;
    paint.setTextAlign（Paint.Align.CENTER）;
    canvas.drawText（你好Android的！（宽/ 2.F），（身高/ 2.F），油漆）;
 

然后你想什么做的位图。例如：

  ImageView的形象=新ImageView的（）;
image.setImageBitmap（位）;
 

I need to create simple image in my application programatically. Simple image is black background with text which is created programatically. Is it possible? Thank you.

解决方案

    int width = 200;
    int height = 100;
    Bitmap bitmap = Bitmap.createBitmap(width, height, Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);

    Paint paint = new Paint();
    paint.setColor(Color.BLACK); 
    paint.setStyle(Paint.Style.FILL);       
    canvas.drawPaint(paint);

    paint.setColor(Color.WHITE);
    paint.setAntiAlias(true);
    paint.setTextSize(14.f);
    paint.setTextAlign(Paint.Align.CENTER);
    canvas.drawText("Hello Android!", (width / 2.f) , (height / 2.f), paint);

And then do whatever you wanted to do with the Bitmap. For example:

ImageView image = new ImageView();
image.setImageBitmap(bitmap);
