我有一个二维码阅读器,当它扫描二维码并获取文本时,我希望代码使用if
函数检查该文本,并显示某个图像。但是由于某种原因,它总是卡在if
函数中...就像它不会将其识别result.getText().ToString()
为字符串...\
public void processPicture(CameraEvent event) {
updateLayout("Please wait...");
if (event.getIndex() == 0) {
if (event.getData() != null && event.getData().length > 0) {
byte[] data = event.getData();
Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length);
int[] intArray = new int[bitmap.getWidth() * bitmap.getHeight()];
//copy pixel data from the Bitmap into the 'intArray' array
bitmap.getPixels(intArray, 0, bitmap.getWidth(), 0, 0, bitmap.getWidth(), bitmap.getHeight());
LuminanceSource source = new RGBLuminanceSource(bitmap.getWidth(), bitmap.getHeight(), intArray);
BinaryBitmap bbmap = new BinaryBitmap(new HybridBinarizer(source));
Reader reader = new QRCodeReader();
int DelayTime = 5000;
boolean error = false;
try {
Result result = reader.decode(bbmap);
Log.d(Constants.LOG_TAG, result.getText());
qc = result.getText().toString();
// updateLayout(result.getText());
if( qc == "zoi"){
Bundle iconBundle = new Bundle();
iconBundle.putInt(Control.Intents.EXTRA_LAYOUT_REFERENCE, R.id.image);
iconBundle.putString(Control.Intents.EXTRA_DATA_URI,
getUriString(R.drawable.zoiko));
currentlyTakingPicture = false;
showLayout(R.layout.layout, new Bundle[] {iconBundle});
}
} catch (NotFoundException e) {
updateLayout("QR Code Not Found");
error = true;
e.printStackTrace();
} catch (ChecksumException e) {
e.printStackTrace();
updateLayout(new String[] {
"QR Code looks corrupted",
"Maybe try again?"
});
error = true;
} catch (FormatException e) {
e.printStackTrace();
updateLayout("That's not a QR Code");
error = true;
}
if (error) {
try {
Thread.sleep(DelayTime);
} catch (InterruptedException e) {
e.printStackTrace();
}
currentlyTakingPicture = false;
updateLayout(DEFAULT_TEXT);
}
}
}
}
