安卓最简单用zxing生成二维码

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);
    }
