Only the original thread that created a view hierarchy can touch its views

Only the original thread that created a view hierarchy can touch its views.

最近在积累自己的Android UI compenent库，在做到自定义相机的时候，点击拍摄按钮，当前的activity会自动finish（），并报以上错误，出错位置在我改变界面组件的visibility属性

rl_resultview.setVisibility(View.VISIBLE);

然后，我做了如下调整，让这部分界面更新在UI主线程中进行

CameraCustomize.this.runOnUiThread(new Runnable() {
    @Override
    public void run() {
        rl_resultview.setVisibility(View.VISIBLE);
    }
});
