1.在module的build.gradle中執行compile操作

compile ‘cn.yipianfengye.android:zxing-library:2.2‘

2.在demo Application中執行初始化操作

@Override
    public void onCreate() {
        super.onCreate();

        ZXingLibrary.initDisplayOpinion(this);
    }

3.在代碼中執行打開掃描二維碼界面操作

  Intent intent = new Intent(MainActivity.this
 
, CaptureActivity.class);
  startActivityForResult(intent, REQUEST_CODE);
//這裏的REQUEST_CODE是我們定義的int型常量

4.在Activity的onActivityResult方法中接收掃描結果

/**
         * 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();
                }
            }
        }
