Android的ZXing获取吧code图像 [英] Android ZXing Get Barcode Image
本文介绍了Android的ZXing获取吧code图像的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我使用Zxing库来产生一个吧code在我的Android应用程序
I am using Zxing library to generate a barcode in my Android application
Intent intent = new Intent("com.google.zxing.client.android.ENCODE");
intent.putExtra("ENCODE_FORMAT", "UPC_A");
intent.putExtra("ENCODE_DATA", "55555555555");
startActivityForResult(intent,0);
反正是有保存在我的应用程序,它被调用Zxing生成的图像?我看到,在我的 onActivityResult
我得到的意图空。
在此先感谢您的帮助
推荐答案
取意见高速缓存,并将其保存在位图这样的事情
Take the views cache and save it in bitmap something like this
View myBarCodeView = view.getRootView()
//Else this might return null
myBarCodeView.setDrawingCacheEnabled(true)
//Save it in bitmap
Bitmap mBitmap = myBarCodeView.getDrawingCache()
或 画出你自己吧code或QR code
OR draw your own barcode or QR CODE
//Change the writers as per your need
private void generateQRCode(String data) {
com.google.zxing.Writer writer = new QRCodeWriter();
String finaldata =Uri.encode(data, "ISO-8859-1");
try {
BitMatrix bm = writer.encode(finaldata,BarcodeFormat.QR_CODE, 350, 350);
mBitmap = Bitmap.createBitmap(350, 350, Config.ARGB_8888);
for (int i = 0; i < 350; i++) {
for (int j = 0; j < 350; j++) {
mBitmap.setPixel(i, j, bm.get(i, j) ? Color.BLACK: Color.WHITE);
}
}
} catch (WriterException e) {
e.printStackTrace();
}
if (mBitmap != null) {
mImageView.setImageBitmap(mBitmap);
}
}
public void generateBarCode(String data){
com.google.zxing.Writer c9 = new Code128Writer();
try {
BitMatrix bm = c9.encode(data,BarcodeFormat.CODE_128,350, 350);
mBitmap = Bitmap.createBitmap(350, 350, Config.ARGB_8888);
for (int i = 0; i < 350; i++) {
for (int j = 0; j < 350; j++) {
mBitmap.setPixel(i, j, bm.get(i, j) ? Color.BLACK : Color.WHITE);
}
}
} catch (WriterException e) {
e.printStackTrace();
}
if (mBitmap != null) {
mImageView.setImageBitmap(mBitmap);
}
}
一旦你的位图图像只是保存
Once you get the bitmap image just save it
//create a file to write bitmap data
File f = new File(FilePath, FileName+".png");
f.createNewFile();
//Convert bitmap to byte array
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ImageBitmap.compress(CompressFormat.PNG, 0, bos);
byte[] bytearray = bos.toByteArray();
//Write bytes in file
FileOutputStream fos = new FileOutputStream(f);
fos.write(bytearray);
fos.flush();
fos.close();
您还可以从github上检查小型图书馆的,我创造了创造吧code或QR $ C $ ç
You can also check a small library from github that i had created to create Barcode or QR Code
GZxingEncoder Encoder = GZxingEncoder.getInstance();
Encoder.initalize(this);
//To generate bar code use this
Bitmap bitmap = Encoder.generateBarCode_general("some text")
