26 | zxing.setViewfinderView((ViewfinderView) findViewById(R.id.preview_view));//设置预览 27 | zxing.setTorch((ToggleButton) findViewById(R.id.torch));//设置闪光灯，可选 28 | ``` 29 | 第二步：处理生命周期 30 | 31 | ```Java 32 | @Override 33 | protected void onResume() { 34 | super.onResume(); 35 | zxing.onResume(); 36 | if (!zxing.isOpen()) {//相机在onResume启动，此处需要判断启动是否失败 37 | new OnFailDialog(this).show(); 38 | } 39 | } 40 | 41 | @Override 42 | protected void onPause() { 43 | super.onPause(); 44 | zxing.onPause(); 45 | } 46 | 47 | @Override 48 | protected void onDestroy() { 49 | super.onDestroy(); 50 | zxing.onDestroy(); 51 | } 52 | ``` 53 | 54 | 第三步：处理回调 55 | 56 | ```Java 57 | @Override 58 | public void onScanReady() {//初始化完成 59 | zxing.requestScan();//开始扫描 60 | } 61 | 62 | @Override 63 | public void onScanSuccess(ScanResult result) {//扫描完成 64 | String scanResult = result.getRawText();//扫描所得原生数据 65 | } 66 | ``` 67 | 68 | 可选： 69 | 70 | ```Java 71 | BeepManager beep;// 播放哔声 72 | InactivityTimer timer;// 自动关闭 73 | 74 | // 自定义扫描的覆盖层 75 | Drawable draw = new ViewfinderView.FrameDrawable(){...}; //FrameDrawable支持定制边框 76 | viewfinderView.setForeground(draw); 77 | ``` 78 | ### License 79 | 80 | Copyright 2017 Yeamy. 81 | 82 | Licensed under the Apache License, Version 2.0 (the "License"); 83 | you may not use this file except in compliance with the License. 84 | You may obtain a copy of the License at 85 | 86 | http://www.apache.org/licenses/LICENSE-2.0 87 | 88 | Unless required by applicable law or agreed to in writing, software 89 | distributed under the License is distributed on an "AS IS" BASIS, WITHOUT 90 | WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.
