        this.context = context;
        this.content = content;
    }

    @Override
    protected int getImplLayoutId() {
        return R.layout.bottom_popup; // 指定自定义布局
    }

    @Override
    protected void onCreate() {
        super.onCreate();
        contView = findViewById(R.id.title);
        contView.setText(this.content);
        // 设置按钮点击事件
        findViewById(R.id.close_button).setOnClickListener(new OnClickListener() {
