Android实现通话自动录音

124 阅读 0 评论 82 点赞

我是靠谱客的博主年轻花生，最近开发中收集的这篇文章主要介绍Android实现通话自动录音，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

最近需要做一个类似于电话客户的功能，要求拨打电话能自动录音。所以写了一个dome，希望能够帮到大家。

主要思路就是监听手机通话状态在监听到接听时开始录音，结束停止录音。

AndroidManifest中配置

<!-- 权限 -->
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
 <uses-permission android:name="android.permission.INTERNET" />
 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
 <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
 <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
 <uses-permission android:name="android.permission.RECORD_AUDIO" />
 <uses-permission android:name="android.permission.VIBRATE" />
 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
 <uses-permission android:name="android.permission.READ_CONTACTS" />
 <uses-permission android:name="android.permission.WRITE_CONTACTS" />
 <uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />
 <uses-permission android:name="android.permission.READ_CALL_LOG" />
 <uses-permission android:name="android.permission.CALL_PHONE" />
 <uses-permission android:name="android.permission.WRITE_CALL_LOG" />
 <uses-permission android:name="android.permission.MANAGE_ACCOUNTS" />
 <uses-permission android:name="android.permission.GET_ACCOUNTS" />
 <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />

当然了还要在清单文件中注册service

public abstract class CommonAdapter<T> extends BaseAdapter{

 protected Context mContext;
 protected List<T> mList;
 protected int mLayoutId;

 public CommonAdapter(Context context, List<T> list, int layoutId) {
  mContext=context;
  mList=list;
  mLayoutId=layoutId;
 }

 //刷新数据
 public void refresh(List<T> list){
  mList=list;
  notifyDataSetChanged();
 }

 @Override
 public int getCount() {
  return mList.size();
 }

 @Override
 public T getItem(int position) {
  return mList.get(position);
 }

 @Override
 public long getItemId(int position) {
  return position;
 }

 @Override
 public View getView(int position, View convertView, ViewGroup parent) {
  ViewHolder holder = ViewHolder.getHolder(mContext, mLayoutId, convertView, parent);
  convertView(holder,mList.get(position));
  return holder.getConvertView();
 }

 public abstract void convertView(ViewHolder holder,T t);
}
