使用Activity
// kotlin调用 Intent(this, QRCodeActivity::class.java) .putExtra(EXTRA_TITLE, "二维码扫描") .putExtra(EXTRA_HINT, "将二维码放入框内，即可自动扫描") .also { startActivityForResult(it, REQUEST_CODE) } override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) { super.onActivityResult(requestCode, resultCode, data) if (requestCode == REQUEST_CODE) { when (resultCode) { Activity.RESULT_OK -> tvResult.append("${data?.getStringExtra(EXTRA_RESULT)}\n\n") Activity.RESULT_CANCELED -> tvResult.append("取消\n\n") } } }
// java调用 final Intent intent = new Intent(MainActivity2.this, QRCodeActivity.class); intent.putExtra(QRCodeActivity.EXTRA_TITLE, "二维码扫描"); intent.putExtra(QRCodeActivity.EXTRA_HINT, "将二维码放入框内，即可自动扫描"); startActivityForResult(intent, REQUEST_CODE); @Override protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) { super.onActivityResult(requestCode, resultCode, data); if (requestCode == REQUEST_CODE) { switch (resultCode) { case RESULT_OK: if (data != null) { tvResult.append(data.getStringExtra(QRCodeActivity.EXTRA_RESULT) + "\n\n"); } break; case RESULT_CANCELED: tvResult.append("取消\n\n"); break; } } }

使用QRCodeView
// kotlin <com.zourw.libqrcode_ktx.QRCodeView android:id="@+id/qrCodeView" android:layout_width="match_parent" android:layout_height="match_parent" app:qr_cornerBreadth="3dp" app:qr_cornerColor="#00ff00" app:qr_cornerLength="30dp" app:qr_gridColor="#00ff00" app:qr_gridColumnCount="30" app:qr_gridRowCount="30" app:qr_offsetXRatio="0.5" app:qr_offsetYRatio="0.5" app:qr_sizeRatio="0.7" /> // java <com.zourw.libqrcode_java.QRCodeView android:id="@+id/qrCodeView" android:layout_width="match_parent" android:layout_height="match_parent" app:qr_cornerBreadth="3dp" app:qr_cornerColor="#03A9F4" app:qr_cornerLength="30dp" app:qr_gridColor="#03A9F4" app:qr_gridColumnCount="30" app:qr_gridRowCount="30" app:qr_offsetXRatio="0.5" app:qr_offsetYRatio="0.5" app:qr_sizeRatio="0.7" />
