今天来请求请求权限吧

    //权限请求
    private void requestPermissions() {
        List<String> permissionList = new ArrayList<>();
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
            permissionList.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);
        }
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
            permissionList.add(Manifest.permission.CALL_PHONE);
        }

        if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            permissionList.add(Manifest.permission.ACCESS_COARSE_LOCATION);
        }

        if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            permissionList.add(Manifest.permission.ACCESS_FINE_LOCATION);
        }

        if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
            permissionList.add(Manifest.permission.READ_EXTERNAL_STORAGE);
        }

        if (ContextCompat.checkSelfPermission(this, Manifest.permission.INTERNET) != PackageManager.PERMISSION_GRANTED) {
            permissionList.add(Manifest.permission.INTERNET);
        }

        if (ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
            permissionList.add(Manifest.permission.CAMERA);
        }

        // if list is not empty will request permissions
        if (!permissionList.isEmpty()) {
            ActivityCompat.requestPermissions(this, permissionList.toArray(new String[permissionList.size()]), 1);
        }
    }

这个函数可以动态请求各种所需权限，有的没的都可以先申请下（记得在AndroidManifest.xml中声明权限哦）
