WeixinUtil.java这个类是定义过的，里面的方法可以直接用的把？我想在点击分享的那个按钮直接调用这里的方法？这样是可以的？

在MainActivity的这样用：

    private void handleShareToWeixin() {
    ImageButton button = (ImageButton)findViewById(R.id.btn_share_to_weixin);
        button.setOnClickListener(new View.OnClickListener() {
            
            @Override
            public void onClick(View v) {
                WeixinUtil.getInstance(MainView.this).sentRequest("text");
            }
        });
    }
