最近公司做了一款OTP令牌激活的产品,由于之前激活手机令牌需要输入很多的激活信息才能进行激活。经过一段使用后,发现易用性不是很强,考虑如果加入二维码的的扫码功能岂不是大大增加了易用性。 在网上搜了很多资料,要不是配置太多,要不就是代码量太大,最后没办法就硬着头皮去写和去精简,最后压缩至目前的版本。如果有更好的版本可以联系我。
具体DEMO可以通过 下载http://download.csdn.net/detail/fugui6611634/7341277下载
本文代码运行的结果如下:
代码的结构如下:
下面主要来看一下配置文件:
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.ft" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".TwoCodeActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name="com.google.zxing.ui.CaptureActivity" android:configChanges="keyboardHidden|orientation" android:screenOrientation="landscape" android:windowSoftInputMode="adjustResize|stateAlwaysHidden" /> </application> <uses-sdk android:minSdkVersion="3" /> <uses-permission android:name="android.permission.READ_PHONE_STATE"/> <uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="android.permission.DEVICE_POWER" /> <uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.VIBRATE" /> <uses-permission android:name="android.permission.FLASHLIGHT" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-feature android:name="android.hardware.camera" /> <uses-feature android:name="android.hardware.camera.autofocus" /> </manifest>
启动类 TwoCodeActivity.java
package com.ft; import android.app.Activity; import android.app.AlertDialog; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.TextView; import com.google.zxing.ui.CaptureActivity; public class TwoCodeActivity extends Activity { public static final int SCAN_CODE = 1; AlertDialog.Builder alertDialog = null; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button button = (Button)this.findViewById(R.id.scan); button.setOnClickListener(new OnClickListener(){ @Override public void onClick(View v) { Intent intent = new Intent(TwoCodeActivity.this, CaptureActivity.class); startActivityForResult(intent, SCAN_CODE); } }); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { TextView textView = (TextView)this.findViewById(R.id.mytext); switch (requestCode) { case SCAN_CODE: if (resultCode == RESULT_OK) { String result = data.getStringExtra("scan_result"); textView.setText("扫描成功:"+result); } else if (resultCode == RESULT_CANCELED) { textView.setText("扫描失败:"); } break; default: break; } } }
