android MediaRecorder實現(xiàn)錄屏?xí)r帶錄音功能
更新時間：2020年04月07日 11:47:59 作者：不再皺眉✔
這篇文章主要介紹了android MediaRecorder錄屏?xí)r帶錄音功能實現(xiàn)代碼，本文通過實例代碼給大家介紹的非常詳細，對大家的學(xué)習(xí)或工作具有一定的參考借鑒價值,需要的朋友可以參考下
下面說說android的事把
最近是不是也會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 先貼一個動態(tài)權(quán)限類
public class TalAllow {
/**
* RECORD_AUDIO 音頻權(quán)限
* WRITE_EXTERNAL_STORAGE 寫入權(quán)限
* CAMERA 相機權(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 插入個鏈接 （上面那個類code碼為100）
判斷是否有權(quán)限
下面重點來了
首先說明一下這個錄屏和錄音是在服務(wù)里面做的，所以呢貼一個服務(wù)類
這個代碼絕對有質(zhì)量 做了很多處理,下面一行一行解讀把
//首先呢實現(xiàn)的是Handle.Callback接口 主要是做時間及計時時間回調(diào)的,會重新寫HandleMessage方法,其實我個覺得跟在括號{} 里面重寫沒啥區(qū)別就是簡潔頁面
public class TalScreenRecordService extends Service implements Handler.Callback {
//這個就不解釋了吧 log
private static final String TAG = "TalScreenRecordService";
//這個類是管理類拿到服務(wù)后會通過下面的類申請錄屏,點擊允許，
//其中會回調(diào)兩個參數(shù),code碼 和 data,都在ActivityForResult中進行判斷code
private MediaProjectionManager mProjectionManager;
//這個會拿到申請的結(jié)果
private MediaProjection mMediaProjection;
//這個類就是我們主要的錄屏錄音的類啦
private MediaRecorder mMediaRecorder;
//這個就是我們要獲取錄制屏幕的大小,像素,等等一些數(shù)據(jù)
//關(guān)于這類更詳細的介紹https://blog.csdn.net/qq_16628781/article/details/62038163
private VirtualDisplay mVirtualDisplay;
//是否正在錄制 false 沒有錄制
private boolean mIsRunning;
//獲取屏幕的寬高和像素密度 稍后貼類
private int mRecordWidth = TalScreenParams.getScreenWidth();
private int mRecordHeight = TalScreenParams.getScreenWidth();
private int mScreenDpi = TalScreenParams.getScreenDpi();
//code data 就是上面說的允許后回調(diào)
private int mResultCode;
private Intent mResultData;
//錄屏文件的保存地址
private String mRecordFilePath;
private Handler mHandler;
//已經(jīng)錄制多少秒了
private int mRecordSeconds = 0;
//handle發(fā)送消息時的what
private static final int MSG_TYPE_COUNT_DOWN = 110;
//這個是繼承Service 必須重寫的方法 這是使用的BindService(生命周期的長短跟activity一致)
@Override
public IBinder onBind(Intent intent) {
return new RecordBinder();
}
//說一說這個返回值的問題吧
// START_STICKY 粘性返回 ,一次失敗,多次啟動,不保留Intent對象
