}

mainactivity跳转到扫描类以及扫描结果回调、

public static final int REQUEST_CODE = 111;

 默认扫描类

Intent intent = new Intent(getApplication(), CaptureActivity.class);
startActivityForResult(intent, REQUEST_CODE);

自定义扫描类

Intent intent = new Intent(MainActivity.this, TwoActivity.class);
startActivityForResult(intent, REQUEST_CODE);

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {/*** 处理二维码扫描结果*/if (requestCode == REQUEST_CODE) {//处理扫描结果（在界面上显示）if (null != data) {Bundle bundle = data.getExtras();if (bundle == null) {return;}if (bundle.getInt(CodeUtils.RESULT_TYPE) == CodeUtils.RESULT_SUCCESS) {String result = bundle.getString(CodeUtils.RESULT_STRING);Toast.makeText(this, "解析结果:" + result, Toast.LENGTH_LONG).show();} else if (bundle.getInt(CodeUtils.RESULT_TYPE) == CodeUtils.RESULT_FAILED) {Toast.makeText(MainActivity.this, "解析二维码失败", Toast.LENGTH_LONG).show();}}}}
