如何在中间创建带有徽标的QR码 [英] How do create QR code with logo in the middle

问题描述

可以使用android在QR码图像中间添加徽标图像吗？



我已经生成了QR码，但现在我需要的是在二维码的中间插入徽标图片。



有没有办法实现这个目标。



这是我的QR代码，带有Logo代码：



> private String LOG_TAG =" GenerateQRCode";

private Bitmap myLogo， bitmap，bitMerged;



public void onClick（查看v）{



EditText qrInput =（EditText） findViewById（R.id.qrInput）;

String qrInputText = qrInput.getText（）。toString（）;

Log.v（LOG_TAG，qrInputText）;

Point point = new Point（）;

// display.getSize（point）;

int width = point.x;

int height = point.y;

int smallerDimension = width<身高？ width：height;

smallerDimension = smallerDimension * 3/4;



//用二维码图像编码

QRCodeEncoder qrCodeEncoder = new QRCodeEncoder（qrInputText，null，Contents.Type.TEXT，BarcodeFormat.QR_CODE.toString（），smallerDimension）;

try {

bitmap = qrCodeEncoder .encodeAsBitmap（）;



myLogo = BitmapFactory.decodeResource（getResources（），R.drawable.image）;



bitMerged = mergeBitmaps（bitmap，myLogo）;



ImageView myImage =（ImageView）findViewById（R.id.imageView1）;



myImage.setImageBitmap（bitMerged）;



} catch（WriterException e）{

e。 printStackTrace（）;

}

}

公共静态位图mergeBitmaps（位图bmp1，位图bmp2）{

位图bmOverlay = Bitmap.createBitmap（bmp1.getWidth（），bmp1.getHeight（），bmp1.getConfig（） ）;

Canvas canvas = new Canvas（bmOverlay）;

canvas.drawBitmap（bmp1，new Matrix（），null）;

canvas .drawBitmap（bmp2,0,0，null）;

返回bmOverlay;

}

}



我不知道有没有人可以指导我清除这个问题..



提前感谢帮助的心。

It is Possible to add logo image in the middle of QR code image using android?

I have generated the QR code but now what i need is need to insert the logo image in the middle of QR code.

Is there any way to achieve this.

Here is my QR code with Logo Generation code:

>private String LOG_TAG = "GenerateQRCode";
private Bitmap myLogo, bitmap, bitMerged;

public void onClick(View v) {

EditText qrInput = (EditText) findViewById(R.id.qrInput);
String qrInputText = qrInput.getText().toString();
Log.v(LOG_TAG, qrInputText);
Point point = new Point();
// display.getSize(point);
int width = point.x;
int height = point.y;
int smallerDimension = width < height ? width : height;
smallerDimension = smallerDimension * 3/4;

//Encode with a QR Code image
QRCodeEncoder qrCodeEncoder = new QRCodeEncoder(qrInputText,null,Contents.Type.TEXT,BarcodeFormat.QR_CODE.toString(),smallerDimension);
try {
bitmap = qrCodeEncoder.encodeAsBitmap();

myLogo = BitmapFactory.decodeResource(getResources(), R.drawable.image);

bitMerged = mergeBitmaps(bitmap, myLogo);

ImageView myImage = (ImageView) findViewById(R.id.imageView1);

myImage.setImageBitmap(bitMerged);

} catch (WriterException e) {
e.printStackTrace();
}
}
public static Bitmap mergeBitmaps(Bitmap bmp1, Bitmap bmp2) {
Bitmap bmOverlay = Bitmap.createBitmap(bmp1.getWidth(), bmp1.getHeight(), bmp1.getConfig());
Canvas canvas = new Canvas(bmOverlay);
canvas.drawBitmap(bmp1, new Matrix(), null);
canvas.drawBitmap(bmp2, 0, 0, null);
return bmOverlay;
}
}

I don't have idea about that could someone please guide me to clear this issue..

Thanks in advance for the helping hearts.

推荐答案

在此尝试 http ：//www.markhagan.me/Samples/Create-QR-Code-With-Logo-ASPNet [ ^ ]

您需要做的是合并两个位图。所以你可以使用画布 [ ^ ]



1.创建画布，为它指定一个位图（QR码位图）。

What you need to do is to merge the two bitmaps. So you can use Canvas[^]

1. create a Canvas, and specify a bitmap (the QR code bitmap) for it.

setBitmap(Bitmap bitmap)

2。将徽标绘制到QR码位图上。

2. draw the logo onto the QR code bitmap.

public void drawBitmap (Bitmap bitmap, Rect src, RectF dst, Paint paint)
