android MediaRecorder realizes recording function when recording screen

Let's talk about android
Will you also encounter the function of recording screen recording in the demand recently, and it is also encountered recently. Now finish the record 1
First of all, the recording screen needs permission to post a dynamic permission class first
public class TalAllow {
/**
* RECORD_AUDIO Audio permissions
* WRITE_EXTERNAL_STORAGE Write permission
* CAMERA Camera permissions
*/
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);
}
}
}
If there is a need to judge the authority, insert a link (the above class code code is 100)
Determine whether you have permission
Here comes the key point
First of all, explain that this recording screen and recording are done in the service, so paste a service class
This code definitely has quality and has done a lot of processing. The following one line and one line will be interpreted
//首先呢实现的是Handle.Callback接口 主要是做时间及计时时间回调的,会重新写HandleMessage方法,其实我个觉得跟在括号{} 里面重写没啥区别就是简洁页面
public class TalScreenRecordService extends Service implements Handler.Callback {
//这个就不解释了吧 log
private static final String TAG = "TalScreenRecordService";
//这个类是管理类拿到服务后会通过下面的类申请录屏,点击允许，
//其中会回调两个参数,code码 和 data,都在ActivityForResult中进行判断code
private MediaProjectionManager mProjectionManager;
//这个会拿到申请的结果
private MediaProjection mMediaProjection;
//这个类就是我们主要的录屏录音的类啦
private MediaRecorder mMediaRecorder;
//这个就是我们要获取录制屏幕的大小,像素,等等1些数据
//关于这类更详细的介绍https://blog.csdn.net/qq_16628781/article/details/62038163
private VirtualDisplay mVirtualDisplay;
//是否正在录制 false 没有录制
private boolean mIsRunning;
//获取屏幕的宽高和像素密度 稍后贴类
private int mRecordWidth = TalScreenParams.getScreenWidth();
private int mRecordHeight = TalScreenParams.getScreenWidth();
private int mScreenDpi = TalScreenParams.getScreenDpi();
//code data 就是上面说的允许后回调
private int mResultCode;
private Intent mResultData;
//录屏文件的保存地址
private String mRecordFilePath;
private Handler mHandler;
//已经录制多少秒了
private int mRecordSeconds = 0;
//handle发送消息时的what
private static final int MSG_TYPE_COUNT_DOWN = 110;
//这个是继承Service 必须重写的方法 这是使用的BindService(生命周期的长短跟activity1致)
