1、重要代碼

1.0、先加上權(quán)限申請

<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.WRITE_EXTERNAL_STORAGE"/><uses-permission android:name="android.permission.RECORD_AUDIO"/>

?

1.1、申請視頻和存儲權(quán)限

//請求視頻和存儲權(quán)限private void requestPermission() {if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE)!= PackageManager.PERMISSION_GRANTED) {ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, STORAGE_REQUEST_CODE);}if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.RECORD_AUDIO)!= PackageManager.PERMISSION_GRANTED) {ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.RECORD_AUDIO}, AUDIO_REQUEST_CODE);}} @Overridepublic void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {super.onRequestPermissionsResult(requestCode, permissions, grantResults);if (requestCode == STORAGE_REQUEST_CODE || requestCode == AUDIO_REQUEST_CODE) {if (grantResults[0] != PackageManager.PERMISSION_GRANTED) {finish();}}}

1.2、申請錄屏和建立錄屏服務(wù)

Intent intent = new Intent(this, RecordService.class);bindService(intent, connection, BIND_AUTO_CREATE); //錄屏權(quán)限同意后返回@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {if (requestCode == RECORD_REQUEST_CODE && resultCode == RESULT_OK) {mediaProjection = projectionManager.getMediaProjection(resultCode, data);recordService.setMediaProject(mediaProjection);recordService.startRecord();startBtn.setText(R.string.stop_record);//設(shè)置文字countTimer();//開始計時openZFB();//打開支付寶luPinStatus = true;//設(shè)置錄屏狀態(tài)為true}} //建立錄屏服務(wù)private ServiceConnection connection = new ServiceConnection() {@Overridepublic void onServiceConnected(ComponentName className, IBinder service) {DisplayMetrics metrics = new DisplayMetrics();getWindowManager().getDefaultDisplay().getMetrics(metrics);RecordService.RecordBinder binder = (RecordService.RecordBinder) service;recordService = binder.getRecordService();recordService.setConfig(metrics.widthPixels, metrics.heightPixels, metrics.densityDpi);startBtn.setEnabled(true);startBtn.setText(recordService.isRunning() ? R.string.stop_record : R.string.start_record);}@Overridepublic void onServiceDisconnected(ComponentName arg0) {}};
