android 6.0 常用权限请求

请求6.0以上手机的读写文件、相机权限，可根据需要自己添加

private static final int REQUEST_PERMISSIONS = 1000;
    private void requestPermissons(){
        String[]  permissions= new String[]{
                Manifest.permission.WRITE_EXTERNAL_STORAGE,
                Manifest.permission.READ_EXTERNAL_STORAGE,//文件读写
                Manifest.permission.CAMERA,//相机
                Manifest.permission.RECORD_AUDIO//音频
         };
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)!= PackageManager.PERMISSION_GRANTED){
            if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)){
                Toast.makeText(this, "用户曾拒绝xxxx", Toast.LENGTH_SHORT).show();
            }else {
                ActivityCompat.requestPermissions(this, permissions, REQUEST_PERMISSIONS);
            }
        }
    }
