Android簡單實現k線圖，
阿新 • • 發佈：2019-02-08
我並沒有根據股票的具體數字進行畫圖，如果大家需要具體實現的話，就需要根據具體的座標和股票值進行比例轉換，轉換好了以後就能進行具體畫圖 了，廢話不多說先上圖給大家看看
下面我就直接貼原始碼了 非常簡單，希望不要噴我
@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);
