mainactivity跳轉到掃描類以及掃描結果回調、

public static final int REQUEST_CODE = 111;

?默認掃描類

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

自定義掃描類

Intent intent = new Intent(MainActivity.this, TwoActivity.class); startActivityForResult(intent, REQUEST_CODE); @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) {/*** 處理二維碼掃描結果*/if (requestCode == REQUEST_CODE) {//處理掃描結果（在界面上顯示）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, "解析結果:" + result, Toast.LENGTH_LONG).show();} else if (bundle.getInt(CodeUtils.RESULT_TYPE) == CodeUtils.RESULT_FAILED) {Toast.makeText(MainActivity.this, "解析二維碼失敗", Toast.LENGTH_LONG).show();}}}}
