Question

我正在尝试使用多次设置内容在一个活动中实现多个布局并再次使用它初始化所有窗口小部件，到目前为止我已经成功了，但我一度陷入困境。

setContentView(R.layout.layout1) - ＆gt; initWidgets1(); - ＆gt; btn1.setOnClickListner() - ＆gt;工作
setContentView(R.layout.layout2) - ＆gt; initWidgets2(); - ＆gt; btn2.setOnClickListner() - ＆gt;工作

但是

handleClick2(View v)
{
Switch (v.getId())
{-------------
---------
Multiple click handles
-----
---
}

Similarly.
handleClick1(View v)
{
Switch (v.getId())
{
-----------
---------
Multiple click handles
-----
---
}

此方法对任何布局都不起作用。

虽然btn.setOnClickListner()有效，但是对于大型列表会占用大量内存，如果有效，后者会很容易。

代码：

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE); 
    setContentView(R.layout.activity_user);
    initCurrUserWidgets();      
    setAdapter();   
    setCurrUserClickListners();
}

private void initNewUsrWidgets() {
    // TODO Auto-generated method stub
           cancel_new_user          =   (TextView)findViewById(R.new_user.cancel_TV);
           name_new_user            =   (TextView)findViewById(R.new_user.name_TV);
           username_new_user        =   (TextView)findViewById(R.new_user.username_TV);
           password_new_user        =   (TextView)findViewById(R.new_user.password_TV);
           phone_new_user           =   (TextView)findViewById(R.new_user.phone_TV);
           email_new_user           =   (TextView)findViewById(R.new_user.email_TV);
           role_new_user            =   (TextView)findViewById(R.new_user.role_TV);
           window_group_new_user    =   (TextView)findViewById(R.new_user.window_group_TV);

我尝试使用set在一个活动中实现多个布局多次内容并再次使用它初始化所有小部件

尝试使用多个活动或片段。大多数人不会做你想做的事。

XML OnClick属性不适用于setContent更改
