* 项目名称：LiuTest
* 类描述： 权限请求工具类
* 创建人：liubing
* 创建时间：2016/10/19 9:44
* 修改人：Administrator
* 修改时间：2016/10/19 9:44
* 修改备注：
* 使用步骤
* 1.在activity中在PERMISSIONS数组中放入该类中所有用到的权限
* private String [] PERMISSIONS = new String[]{
* Manifest.permission.CALL_PHONE,
* Manifest.permission.READ_PHONE_STATE
* };
* 2. 点击拨打电话时调用requestPer方法判断
* findViewById(R.id.button).setOnClickListener(new View.OnClickListener() {
* @Override public void onClick(View v) {
* if (RequstPermissionsUtil.requestPer(MainActivity.this, PERMISSIONS[0],0))
* {
* Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:4001851518"));
* startActivity(intent);
* }
* }
* });
* 3.在activity中的onRequestPermissionsResult方法中调用RequstPermissionsUtil.onRequestPermissionsResult方法将数据传进去进行回调
* @Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
* super.onRequestPermissionsResult(requestCode, permissions, grantResults);
* RequstPermissionsUtil.onRequestPermissionsResult(MainActivity.this,PERMISSIONS[requestCode],requestCode,permissions,grantResults);
* }
