            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            //初始化控件
            pbHorizontal = findViewById(R.id.pbCircle);
            button = findViewById(R.id.button);

                @Override
                public void onClick(View v) {
                    //setProgress()设置进度条进度，getProgress获取进度条进度
                    pbHorizontal.setProgress(pbHorizontal.getProgress()+10);
                }
