zXing 扫码问题

[JakeWang123]

1.布局如下 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/fragmentContainer" android:layout_width="match_parent" android:layout_height="match_parent"

   >
    <cn.bingoogolapple.qrcode.zxing.ZXingView
        android:id="@+id/zxingview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:qrcv_animTime="1000"
        app:qrcv_barCodeTipText="将条码放入框内，即可自动扫描"
        app:qrcv_barcodeRectHeight="140dp"
        app:qrcv_borderColor="@android:color/white"
        app:qrcv_borderSize="1dp"
        app:qrcv_cornerColor="@color/colorPrimaryDark"
        app:qrcv_cornerLength="20dp"
        app:qrcv_cornerSize="3dp"
        app:qrcv_isBarcode="false"
        app:qrcv_isOnlyDecodeScanBoxArea="true"
        app:qrcv_isScanLineReverse="true"
        app:qrcv_isShowDefaultGridScanLineDrawable="true"
        app:qrcv_isShowDefaultScanLineDrawable="false"
        app:qrcv_isShowTipBackground="true"
        app:qrcv_isShowTipTextAsSingleLine="false"
        app:qrcv_isTipTextBelowRect="false"
        app:qrcv_maskColor="#33FFFFFF"
        app:qrcv_qrCodeTipText="将二维码/条码放入框内，即可自动扫描"
        app:qrcv_rectWidth="200dp"
        app:qrcv_scanLineColor="@color/colorPrimaryDark"
        app:qrcv_scanLineMargin="0dp"
        app:qrcv_scanLineSize="1dp"
        app:qrcv_tipTextColor="@android:color/white"
        app:qrcv_tipTextSize="12sp"
        app:qrcv_toolbarHeight="56dp"
        app:qrcv_topOffset="90dp" />

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:layout_alignParentTop="true"
    android:background="@color/colorPrimary"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" />

    <ImageView
        android:id="@+id/iv_torch"
        android:layout_height="@dimen/height_button"
        android:layout_width="@dimen/height_button"
        android:background="@drawable/bg_circle_dark"
        android:padding="12dp"
        android:layout_centerHorizontal="true"
        android:layout_alignParentBottom="true"
        android:layout_marginBottom="24dp"
        android:src="@drawable/ic_bt_torch_normal"/>
    </RelativeLayout>

2.调用如下： @BindView(R.id.zxingview) ZXingView zxingview; @BindView(R.id.iv_torch) ImageView ivTorch; boolean isOpenFlashlight;

@Override
protected int provideContentViewId() {
    return R.layout.activity_warehouse_out_stock;
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setSupportActionBar((Toolbar) findViewById(R.id.toolbar));
   /* tv_title.setText(R.string.repository_scan_out);
    mActionBar.setDisplayShowTitleEnabled(false);
    mActionBar.setDisplayHomeAsUpEnabled(true);*/
}

@Override
protected void onStart() {
    super.onStart();
    zxingview.startCamera();
    //zxingview.startSpotAndShowRect();

// mQRCodeView.startCamera(Camera.CameraInfo.CAMERA_FACING_FRONT); }

@Override
protected void onStop() {
    zxingview.stopCamera();
    //zxingview.stopSpotAndHiddenRect();
    super.onStop();
}

@Override
protected void onDestroy() {
    zxingview.onDestroy();
    super.onDestroy();
}

private void vibrate() {
    Vibrator vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE);
    vibrator.vibrate(200);
}

@Override
public void onScanQRCodeSuccess(String result) {
    ToastUtils.showShortTime(result);
    vibrate();
    zxingview.startSpot();
}

@Override
public void onScanQRCodeOpenCameraError() {
    Toast.makeText(this, "onScanQRCodeOpenCameraError", Toast.LENGTH_SHORT).show();
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

}

@OnClick(R.id.iv_torch)
public void onClick() {
    zxingview.startSpotAndShowRect();

/* if (isOpenFlashlight) { zxingview.startSpotAndShowRect(); ivTorch.setImageResource(R.drawable.ic_bt_torch_normal); zxingview.closeFlashlight(); isOpenFlashlight = false;

    } else {
        ivTorch.setImageResource(R.drawable.ic_bt_torch_pressed);
        zxingview.openFlashlight();
        isOpenFlashlight = true;
    }*/

}

3.我debug 了一下卡在 rawResult = mMultiFormatReader.decodeWithState(new BinaryBitmap(new HybridBinarizer(source)));：

@Override public String processData(byte[] data, int width, int height) { String result = null; Result rawResult = null;

    try {
        PlanarYUVLuminanceSource source = null;
        Rect rect = mScanBoxView.getScanBoxAreaRect(height);
        if (rect != null) {
            source = new PlanarYUVLuminanceSource(data, width, height, rect.left, rect.top, rect.width(), rect.height(), false);
        } else {
            source = new PlanarYUVLuminanceSource(data, width, height, 0, 0, width, height, false);
        }
        rawResult = mMultiFormatReader.decodeWithState(new BinaryBitmap(new HybridBinarizer(source)));
    } catch (Exception e) {
    } finally {
        mMultiFormatReader.reset();
    }

    if (rawResult != null) {
        result = rawResult.getText();
    }
    return result;
}

@JakeWang123 并没有看到你提的是什么问题！
