下面說(shuō)說(shuō)android的事把

最近是不是也會(huì)遇到需求中需要用到錄屏錄音的功能,最近也是遇到的 現(xiàn)在整理完記錄一下

首先呢,錄音錄屏需要權(quán)限 先貼一個(gè)動(dòng)態(tài)權(quán)限類(lèi)

public class TalAllow { /** * RECORD_AUDIO 音頻權(quán)限 * WRITE_EXTERNAL_STORAGE 寫(xiě)入權(quán)限 * CAMERA相機(jī)權(quán)限 */ public static void requestPermissions(Context context,int allowCode) { ArrayList<String> ps = new ArrayList<>(); int per = ContextCompat.checkSelfPermission(context, Manifest.permission.RECORD_AUDIO); if (per != PackageManager.PERMISSION_GRANTED) { ps.add(Manifest.permission.RECORD_AUDIO); } per = ContextCompat.checkSelfPermission(context, Manifest.permission.WRITE_EXTERNAL_STORAGE); if (per != PackageManager.PERMISSION_GRANTED) { ps.add(Manifest.permission.WRITE_EXTERNAL_STORAGE); } per = ContextCompat.checkSelfPermission(context, Manifest.permission.CAMERA); if (per != PackageManager.PERMISSION_GRANTED) { ps.add(Manifest.permission.CAMERA); } per = ContextCompat.checkSelfPermission(context, Manifest.permission.READ_PHONE_STATE); if (per != PackageManager.PERMISSION_GRANTED) { ps.add(Manifest.permission.READ_PHONE_STATE); } Log.d(TAG, 'requestPermissions:ps=' + ps.size()); if (!ps.isEmpty()) { String[] ps3 = new String[ps.size()]; ps.toArray(ps3); ActivityCompat.requestPermissions((Activity) context, ps3, allowCode); } }}

有需求需要判斷權(quán)限的呢 插入個(gè)鏈接 （上面那個(gè)類(lèi)code碼為100）判斷是否有權(quán)限

下面重點(diǎn)來(lái)了

首先說(shuō)明一下這個(gè)錄屏和錄音是在服務(wù)里面做的，所以呢貼一個(gè)服務(wù)類(lèi)這個(gè)代碼絕對(duì)有質(zhì)量 做了很多處理,下面一行一行解讀把

//首先呢實(shí)現(xiàn)的是Handle.Callback接口 主要是做時(shí)間及計(jì)時(shí)時(shí)間回調(diào)的,會(huì)重新寫(xiě)HandleMessage方法,其實(shí)我個(gè)覺(jué)得跟在括號(hào){} 里面重寫(xiě)沒(méi)啥區(qū)別就是簡(jiǎn)潔頁(yè)面public class TalScreenRecordService extends Service implements Handler.Callback {//這個(gè)就不解釋了吧 log private static final String TAG = 'TalScreenRecordService';

下面貼關(guān)于手機(jī)像素還有dpi的類(lèi)
