編輯你的代碼，在頂部

private int whichLayout = 0; 

然後一個私有變量，當你拿到包做到這一點：

 switch(btnNumber) 
    { 
     case 1 : setContentView(R.layout.first_layout); whichLayout = 1; break; 
     case 2 : setContentView(R.layout.second_layout); whichLayout = 2; break; 
     default: //Handle this 
    } 

最後編輯您的onClick監聽器是這樣的：

public void onClick(View arg0) { 

    switch(whichLayout) { 
    case 1: {//Do what you want; } break; 
    case 2: {//Do what you want; } break; 
    default: //Handle this 
}
