在build.gradle,app的那個,加入這些:android
repositories { mavenCentral() maven { url "http://dl.bintray.com/journeyapps/maven" } } dependencies { // Supports Android 4.0.3 and later (API level 15) compile 'com.journeyapps:zxing-android-embedded:2.0.1@aar' // Supports Android 2.1 and later (API level 7), but not optimal for later Android versions. // If you only plan on supporting Android 4.0.3 and up, you don't need to include this. compile 'com.journeyapps:zxing-android-legacy:2.0.1@aar' // Convenience library to launch the scanning and encoding Activities. // It automatically picks the best scanning library from the above two, depending on the // Android version and what is available. compile 'com.journeyapps:zxing-android-integration:2.0.1@aar' // Version 3.0.x of zxing core contains some code that is not compatible on Android 2.2 and earlier. // This mostly affects encoding, but you should test if you plan to support these versions. // Older versions e.g. 2.2 may also work if you need support for older Android versions. compile 'com.google.zxing:core:3.0.1' }
用的時候,這裏有個例子app
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // Scanner mButton = (Button) findViewById(R.id.assistant_button); mButton.setonclickListener(new View.onclickListener() { @Override public void onclick(View v) { IntentIntegrator integrator = new IntentIntegrator(MainActivity.this); integrator.initiateScan(); } }); } public void onActivityResult(int requestCode, int resultCode, Intent intent) { IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent); if (scanResult != null) { String re = scanResult.getContents(); Log.d("code", re); } // else continue with any other code you need in the method }
