这里介绍两种方式，如下：

一、逐次

private static final int PERMISSION_READ_EXTERNAL_STORAGE = 101;
private static final int PERMISSION_WRITE_EXTERNAL_STORAGE = 102;
private static final int PERMISSION_CAMERA = 103;
private void requestPermission() {
 if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)== PackageManager.PERMISSION_DENIED) {
  ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, PERMISSION_WRITE_EXTERNAL_STORAGE);
 }
 if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_DENIED) {
  ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, PERMISSION_READ_EXTERNAL_STORAGE);
 }
 if (ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) == PackageManager.PERMISSION_DENIED) {
  ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CAMERA}, PERMISSION_CAMERA);
 }
}


@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int []grantResults) {
 switch (requestCode) {
  case PERMISSION_CAMERA: {
   if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {


   } else {
    Toast.makeText(this, "没有摄像头权限我什么都做不了哦!", Toast.LENGTH_LONG).show();
   }
   break;
  }
  case PERMISSION_READ_EXTERNAL_STORAGE: {
   if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {


   } else {
    Toast.makeText(this, "请打开存储读写权限，确保APP正常运行", Toast.LENGTH_LONG).show();;
   }
   break;
  }
  case PERMISSION_WRITE_EXTERNAL_STORAGE: {
   if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {


   } else {
    Toast.makeText(this, "请打开存储读写权限，确保APP正常运行", Toast.LENGTH_LONG).show();;
   }
   break;
  }
 }
}

二、全部

private void requestPermission() {

 List<String> permissionsNeeded = new ArrayList<String>();

 if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)== PackageManager.PERMISSION_DENIED) {
  permissionsNeeded.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);
 }
 if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_DENIED) {
  permissionsNeeded.add(Manifest.permission.READ_EXTERNAL_STORAGE);

 }
 if (ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) == PackageManager.PERMISSION_DENIED) {
  permissionsNeeded.add(Manifest.permission.CAMERA);

 }
 if(permissionsNeeded.size()>0){
  ActivityCompat.requestPermissions(this, permissionsNeeded.toArray(new String[permissionsNeeded.size()]), 1);
 }
}

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int []grantResults) {
 switch (requestCode) {
  case 1: {
   if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
    if (grantResults.length > 0 && grantResults[1] == PackageManager.PERMISSION_GRANTED) {
     if (grantResults.length > 0 && grantResults[2] == PackageManager.PERMISSION_GRANTED) {

     } else {
      dialog();
     }
    } else {
     dialog();
    }
   } else {
    dialog();
   }
   break;
  }
 }
}
