Android6.0以及更高的版本需要动态申请权限，在manifest中配置好权限之后，然后再动态申请所需权限，这里整理一下方便后期使用，代码如下：

public class MainActivity extends BaseActivity {
    public String[] per = new String[]{
            Manifest.permission.INTERNET,
            Manifest.permission.READ_EXTERNAL_STORAGE,
            Manifest.permission.WRITE_EXTERNAL_STORAGE,
            Manifest.permission.CAMERA
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

    }

    @Override
    protected int initLayout() {
        return R.layout.activity_main;
    }

    @Override
    protected void initView() {
        boolean isAllGranted = checkPermissionAllGranted(per);
        if (!isAllGranted) {
            ActivityCompat.requestPermissions(this, per,
                    0);
        } else {
            initElement();
        }


    }

    private void initElement() {
        findViewById(R.id.text).setOnClickListener(new OnSingleClickListener() {
            @Override
            public void onSingleClick(View view) {
                SecondActivity.startActivity(MainActivity.this);
            }
        });
    }

    @Override
    protected void initData() {

    }

    /**
     * 检查是否有指定的权限
     *
     * @param permissions 权限列表
     * @return 是否有权限
     */
    private boolean checkPermissionAllGranted(String[] permissions) {
        for (String permission : permissions) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                if (getApplicationContext().checkSelfPermission(permission) != PackageManager.PERMISSION_GRANTED) {
                    return false;
                }
            }
        }
        return true;
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if (requestCode == 0) {
            boolean isAllGranted = true;
            for (int grant : grantResults) {
                if (grant != PackageManager.PERMISSION_GRANTED) {
                    isAllGranted = false;
                    break;
                }
            }

            if (isAllGranted) {
                Toast.makeText(this, "已授权 ", Toast.LENGTH_SHORT).show();
                initElement();
            } else {
                Toast.makeText(this, "未授权 ", Toast.LENGTH_SHORT).show();
                finish();
            }
        }
    }
}
