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" />

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);
}
