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 現在整理完記錄一下

首先呢,錄音錄屏需要許可權 先貼一個動態許可權類

public class TalAllow {
  /**
   * RECORD_AUDIO     音訊許可權
   * WRITE_EXTERNAL_STORAGE 寫入許可權
   * CAMERA        相機許可權
   */
  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);
    }
  }
}

有需求需要判斷許可權的呢 插入個連結 （上面那個類code碼為100）
判斷是否有許可權

下面重點來了

首先說明一下這個錄屏和錄音是在服務裡面做的，所以呢貼一個服務類
這個程式碼絕對有質量 做了很多處理,下面一行一行解讀把

//首先呢實現的是Handle.Callback介面 主要是做時間及計時時間回撥的,會重新寫HandleMessage方法,其實我個覺得跟在括號{} 裡面重寫沒啥區別就是簡潔頁面
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後會通過下面的類申請錄屏,點選允許，
  //其中會回撥兩個引數,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製螢幕的大小,畫素,等等一些資料
  //關於這類更詳細的介紹https://blog.csdn.net/qq_16628781/article/details/62038163
  private VirtualDisplay mVirtualDisplay;
 //是否正在錄製 false 沒有錄製
  private boolean mIsRunning;
  //獲取螢幕的寬高和畫素密度 稍後貼類
  private int mRecordWidth = TalScreenParams.getScreenWidth();
  private int mRecordHeight = TalScreenParams.getScreenWidth();
  private int mScreenDpi = TalScreenParams.getScreenDpi();
 //code data 就是上面說的允許後回撥
  private int mResultCode;
  private Intent mResultData;
  //錄屏檔案的儲存地址
  private String mRecordFilePath;
  private Handler mHandler;
  //已經錄製多少秒了
  private int mRecordSeconds = 0;
  //handle傳送訊息時的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(生命週期的長短跟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物件
 //關於返回值問題https://blog.csdn.net/github_37663523/article/details/78811539

    mIsRunning = false;

    //getMediaProjection(code,data)不知道這樣寫看不看的董

到了最後了,是一些呼叫時的內容

public class MainActivity extends AppCompatActivity {
  private static final String TAG = MainActivity.class.getSimpleName();
  private Button mBtn;
  private final int REQUEST_ALLOW = 100;
  private Button mButton;
  //bindService需要建立連線
  private ServiceConnection mConnection = new ServiceConnection() {
    @Override
    public void onServiceConnected(ComponentName name,IBinder service) {
      //啟動service
      TalScreenRecordService.RecordBinder recordBinder = (TalScreenRecordService.RecordBinder) service;
      TalScreenRecordService recordService = recordBinder.getRecordService();
      //這個其實是傳值在使用的activity中拿到Service
      TalScreenUtils.setScreenService(recordService);
    }
    @Override
    public void onServiceDisconnected(ComponentName name) {
    }
  };
 //開啟service,意圖跳轉到service,別忘了AndroidManifest裡面需要註冊這個service哦
  private void startService() {
    Intent intent = new Intent(MainActivity.this,TalScreenRecordService.class);
    bindService(intent,mConnection,BIND_AUTO_CREATE);
  }
  @Override
  protected void onCreate(final Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mBtn = findViewById(R.id.btn);
    mButton = findViewById(R.id.button2);
    initView();
    //兩個按鈕 一個開始 一個結束 xml不貼了
    mBtn.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
        if (TalFileUtils.getFreeMem(MainActivity.this) < 100) {
          Toast.makeText(MainActivity.this,"手機記憶體不足,請清理後再進行錄屏",Toast.LENGTH_SHORT).show();
          return;
        }
        //開始錄屏錄音
        TalScreenUtils.startScreenRecord(MainActivity.this,REQUEST_ALLOW);
      }
    });
    mButton.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
        stop();
        Log.i(TAG,"onClick: " + stop());
      }
  //停止錄屏錄音返回路徑
      private String stop() {
        TalScreenUtils.stopScreenRecord(MainActivity.this);//停止
        return TalScreenUtils.getScreenRecordFilePath();
      }
    });
  }
  @Override
  protected void onStart() {
    super.onStart();

  }

  private void initView() {
    //許可權申請
    TalAllow.requestPermissions(this,REQUEST_ALLOW);
    //獲取螢幕大小 在onCreate裡面初始化就可以獲取
    TalScreenParams.init(this);
    startService();
  }

  @Override
  protected void onStop() {
    super.onStop();
    //在對使用者可見不可互動的時候防止異常
    TalScreenUtils.clear();
  }
 //列印許可權獲取情況日誌
  @Override
  public void onRequestPermissionsResult(int requestCode,@NonNull String[] permissions,@NonNull int[] grantResults) {
    Toast.makeText(this,permissions[0] + "\n" + grantResults[0],Toast.LENGTH_SHORT).show();
    super.onRequestPermissionsResult(requestCode,permissions,grantResults);
  }
 //在使用者允許錄屏後拿到確定的code 跟data
  @Override
  protected void onActivityResult(int requestCode,int resultCode,@Nullable Intent data) {
    super.onActivityResult(requestCode,resultCode,data);
    if (requestCode == REQUEST_ALLOW && data != null) {
      try {
      //設定資料，在使用者允許後 呼叫了開始錄屏的方法
        TalScreenUtils.setUpData(resultCode,data);
        //拿到路徑
        String screenRecordFilePath = TalScreenUtils.getScreenRecordFilePath();
        if (screenRecordFilePath == null) {
          Toast.makeText(this,"空的",Toast.LENGTH_SHORT).show();
        }
        Toast.makeText(MainActivity.this,"" + screenRecordFilePath,Toast.LENGTH_SHORT).show();
        Log.i("zlq","onClick: " + screenRecordFilePath);
      } catch (Exception e) {
        e.printStackTrace();
      }
    } else {
      Toast.makeText(this,"禁止錄屏",Toast.LENGTH_SHORT).show();
    }
  }

  @Override
  protected void onDestroy() {
    super.onDestroy();
    unbindService(mConnection);
  }
}

至此，一個還算比較完整的錄屏錄音功能就可以實現,不足之處請批評指正
