Android简单实现k线图，

来源：互联网发布：网络称谓谜材编辑：程序博客网时间：2024/05/16 06:35

我并没有根据股票的具体数字进行画图，如果大家需要具体实现的话，就需要根据具体的坐标和股票值进行比例转换，转换好了以后就能进行具体画图了，废话不多说先上图给大家看看

下面我就直接贴源码了非常简单，希望不要喷我
@Override
protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      Display display = getWindowManager().getDefaultDisplay();
      bitmap = Bitmap.createBitmap(display.getWidth(), display.getHeight(), Bitmap.Config.ARGB_8888);
      img = (ImageView) findViewById(R.id.img);
      img.setImageBitmap(bitmap);
      initCanvas();
      initPanit();
      drawMap();
      initText();
      drawKmap();
}

private void initText() {
      canvas.drawText("200",200,1650,paint);
      canvas.drawText("400",400,1650,paint);
      canvas.drawText("600",600,1650,paint);
      canvas.drawText("800",800,1650,paint);
      canvas.drawText("1000",1000,1650,paint);
      canvas.drawText("1200",1200,1650,paint);
      canvas.drawText("1400",1400,1650,paint);
      canvas.drawText("1600",1600,1650,paint);

      //x轴
      canvas.drawText("200",20,1600,paint);
      canvas.drawText("400",20,1400,paint);
      canvas.drawText("600",20,1200,paint);

      canvas.drawText("1600",0,200,paint);
      img.setImageBitmap(bitmap);
      img.invalidate();
}
private void drawKmap() {
      canvas.drawLine(288,968,395,1300,paint);
      canvas.drawLine(395,1300,554,1266,paint);

      canvas.drawLine(788,715,891,758,paint);
      canvas.drawLine(891,758,1256,136,paint);
      img.setImageBitmap(bitmap);
      img.invalidate();
}
private void drawMap() {
      canvas.drawLine(150f, 120f, 150f, 1700f, paint);
      canvas.drawLine(0f, 1600f, 1500f, 1600f, paint);
}
private void initPanit() {
      paint = new Paint();
      paint.setColor(Color.RED);
      paint.setStrokeWidth(10);
      paint.setTextSize(50);
}
Canvas canvas;
private void initCanvas() {
   canvas = new Canvas();
      canvas.setBitmap(bitmap);

}
