嗨！我怎么能进入我从微调选择的布局？

Question

我有三个选择从微调，如果我选择（例如：“选择模式”），然后点击下一个按钮来发送我选择的布局， 等等，我想使用开关案件，但我不知道如何做到这一点

Answer 1

做这样的事情。当动态切换视图时，我建议查看片段。

spinner1.setOnItemSelectedListener(new OnItemSelectedListener() { 
@Override 
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) { 
    switch (positiion) { 
     case 0: loadView1(); 
       break; 
     case 1: loadView2(); 
       break; 
     case 2: loadView3(); 
       break; 
    } 
} 

@Override 
public void onNothingSelected(AdapterView<?> parentView) { 
    // your code here 
} 

});
