Android開源-Zbar掃描(代碼比zxing簡單N倍，掃描速度也夠快是zxing的3~5倍)

我找AndroidZbar的代碼找了好久，兄弟們有福了，這是github上的一個基于Zbar的開源庫 BGAQRCode (這個庫真的很棒)。

代碼結構：

你可以先運行，看下得到的app，反正我沒用過zbar，但是看完demoApp就會改代碼了，你把它鑲嵌入自己的app最多2小時

主要用到的東西：

MainActivity.java

其實就是跳轉界面

TestScanActivity

public class TestScanActivity extends AppCompatActivity implements QRCodeView.Delegate {
    private static final String TAG = TestScanActivity.class.getSimpleName();

    private QRCodeView mQRCodeView;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test_scan);
        setSupportActionBar((Toolbar) findViewById(R.id.toolbar));

        mQRCodeView = (ZBarView) findViewById(R.id.zbarview);
        mQRCodeView.setDelegate(this);
    }

    @Override
    protected void onStart() {
        super.onStart();
        mQRCodeView.startCamera();
    }

    @Override
    protected void onStop() {
        mQRCodeView.stopCamera();
        super.onStop();
    }

    @Override
    protected void onDestroy() {
        mQRCodeView.onDestroy();
        super.onDestroy();
    }
    private void vibrate() {
        Vibrator vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE);
        vibrator.vibrate(200);
    }
//下面這個方法就是返回掃描結果的
    @Override
    public void onScanQRCodeSuccess(String result) {
        Log.i(TAG, "result:" + result);
        Toast.makeText(this, result, Toast.LENGTH_SHORT).show();
        vibrate();
        mQRCodeView.startSpot();
    }

    @Override
    public void onScanQRCodeOpenCameraError() {
        Log.e(TAG, "打開相機出錯");
    }

    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.start_spot:
                mQRCodeView.startSpot();
                break;
            case R.id.stop_spot:
                mQRCodeView.stopSpot();
                break;
            case R.id.start_spot_showrect:
                mQRCodeView.startSpotAndShowRect();
                break;
            case R.id.stop_spot_hiddenrect:
                mQRCodeView.stopSpotAndHiddenRect();
                break;
            case R.id.show_rect:
                mQRCodeView.showScanRect();
                break;
            case R.id.hidden_rect:
                mQRCodeView.hiddenScanRect();
                break;
            case R.id.start_preview:
                mQRCodeView.startCamera();
                break;
            case R.id.stop_preview:
                mQRCodeView.stopCamera();
                break;
            case R.id.open_flashlight:
                mQRCodeView.openFlashlight();
                break;
            case R.id.close_flashlight:
                mQRCodeView.closeFlashlight();
                break;
            case R.id.scan_barcode:
                mQRCodeView.changeToScanBarcodeStyle();
                break;
            case R.id.scan_qrcode:
                mQRCodeView.changeToScanQRCodeStyle();
                break;
        }
    }

R.layout.activity_test_scan

基本只要改這上邊兩個類，代碼比zxing簡單N倍，掃描速度也夠快是zxing的3~5倍（我覺得用zxing的公司可能做了大量代碼算法優化，所以他們用zxing），畢竟Zbar基于c，對于單純的對掃描速度的有要求，就算我們們不優化代碼，也滿足我們的需要
