pda的广播扫码 uni-app 安卓端详细步骤

以下是在uni-app中实现PDA的广播扫码功能的详细步骤：

1. 在manifest.json文件中添加以下权限：

"android": {
  "permission": [
    "android.permission.INTERNET",
    "android.permission.ACCESS_NETWORK_STATE",
    "android.permission.ACCESS_WIFI_STATE",
    "android.permission.CHANGE_WIFI_STATE",
    "android.permission.WAKE_LOCK",
    "android.permission.READ_EXTERNAL_STORAGE",
    "android.permission.WRITE_EXTERNAL_STORAGE",
    "android.permission.CAMERA",
    "android.permission.FLASHLIGHT",
    "android.permission.VIBRATE",
    "com.android.launcher.permission.INSTALL_SHORTCUT"
  ]
}

2. 在App.vue文件中添加以下代码：

<template>
  <div>
    <button @click="scan">扫码</button>
  </div>
</template>

<script>
export default {
  methods: {
    scan() {
      let Intent = plus.android.importClass("android.content.Intent");
      let IntentFilter = plus.android.importClass("android.content.IntentFilter");
      let BarcodeFormat = plus.android.importClass("com.google.zxing.BarcodeFormat");
      let DecodeHintType = plus.android.importClass("com.google.zxing.DecodeHintType");
      let activity = plus.android.runtimeMainActivity();
      let filter = new IntentFilter();
      filter.addAction("com.google.zxing.client.android.SCAN");
      let formats = new Array();
      formats.push(BarcodeFormat.QR_CODE);
      let hints = new plus.android.getDecodeHintType();
      hints.put(DecodeHintType.POSSIBLE_FORMATS, formats);
      activity.registerReceiver(
        new plus.android.implementsReceiver({
          onReceive: function(intent) {
            let result = intent.getStringExtra("SCAN_RESULT");
            alert(result);
          }
        }),
        filter
      );
      let scanIntent = new Intent("com.google.zxing.client.android.SCAN");
      scanIntent.putExtra("SCAN_MODE", "QR_CODE_MODE");
      scanIntent.putExtra("SCAN_WIDTH", 800);
      scanIntent.putExtra("SCAN_HEIGHT", 800);
      scanIntent.putExtra("SCAN_FORMATS", "QR_CODE");
      scanIntent.putExtra("EXTRA_SCAN_RESULT_ORIENTATION", "landscape");
      scanIntent.putExtra("EXTRA_SCAN_RESULT_DISPLAY_DURATION_MS", 1000);
      scanIntent.putExtra("EXTRA_SCAN_RESULT_VIEWFINDER_WIDTH", 800);
      scanIntent.putExtra("EXTRA_SCAN_RESULT_VIEWFINDER_HEIGHT", 800);
      activity.startActivityForResult(scanIntent, 0);
    }
  }
};
</script>

3. 在main.js文件中添加以下代码：

import Vue from "vue";
import App from "./App.vue";

Vue.config.productionTip = false;

// 在plusReady中执行扫码
document.addEventListener(
  "plusready",
  function() {
    new Vue({
      render: h => h(App)
    }).$mount("#app");
  },
  false
);
