最近看了一下安卓生成二维码,我写代码以简洁为主,看了看各位大牛写的都太复杂,自己总结了下,自己以后忘了看看,若是能帮到各位,兄弟甚是开心。
直接点击按钮生成。ed_text为一个文本输入框。
public void open(View view) throws WriterException { String text = ed_text.getText().toString(); /*String match = "^[1-9][0-9]{}";*/ if (text.equals("")){ Toast.makeText(context, "输入为空", Toast.LENGTH_SHORT).show(); }else { Bitmap bitmap; BitMatrix result; MultiFormatWriter multiFormatWriter = new MultiFormatWriter(); result = multiFormatWriter.encode(text, BarcodeFormat.QR_CODE,200,200); int w = result.getWidth(); int h = result.getHeight(); int[] pixels = new int[w * h]; for (int y = 0; y < h; y++) { int offset = y * w; for (int x = 0; x < w; x++) { pixels[offset + x] = result.get(x, y) ? BLACK : WHITE; } } bitmap = Bitmap.createBitmap(w,h,Bitmap.Config.ARGB_8888); bitmap.setPixels(pixels,0,200,0,0,w,h); iv_x.setImageBitmap(bitmap); }
