單擊ListView項目，根據點擊的項目打開顯示佈局的活動？

Question

在我的應用程序中，我有一個MainActivity包含許多可以單擊的項目（ListView）。如果點擊某個項目，我希望它打開下一個活動（例如NextActivity），該活動顯示與用戶在前一個屏幕上單擊了哪個項目相關的xml佈局。 這是我的完整MainActivity代碼：

public class MainActivity extends ListActivity { 
private LayoutInflater mInflater;

RowData rd;

    "Temaki Sushi", "Oyakodon", "Okonomiyaki", "Tofu Dango", "Oden", //5

    };

    "Variation of Sushis from fresh vegetables and seafoods! Good for family occassions!", 
    "Oyakodon is a Japanese Rice Bowl dish with Chicken, Eggs and various sorts of healthy and delicious Veggetables!", 
    "Japanese assorted Pancake that is made from many different ingredients. The taste is so delicious!", 
    "Japanese Dumplings made of Rice Flour. This one of the healthiest sweets in Japan!", 
    "Japanese assorted stews. Made from many different kind of veggetables. Popular in Winter!", //5 
    "Stew made of Beef and Veggetables. Very delicious and delightful! Yummy!", 
    "new era", 
    "new era",

如何編寫代碼NextActivity顯示基於項目的佈局點擊？例如，如果項目0被點擊，setContentView（R.layout.item0），如果項目1被點擊，setContentView（R.layout.item1）等等？

Answer 1

在MainActivity在onListItemClick部分：

Bundle bundle = new Bundle(); 
bundle.putint("Layout", position); 

Intent newIntent = new Intent(this.getApplicationContext(), NextActivity.class); 
newIntent.putExtras(bundle); 
startActivityForResult(newIntent, 0); 

，第二部分是像晴天說：

Bundle bundle = this.getIntent().getExtras(); 
int chooser = bundle.getInt("Layout"); 

switch(chooser) { 
case 0: 
setContentView(R.layout.main0); 
break; 

case 1: 
setContentView(R.layout.main1); 
break; 
...... 
...... 
} and so o 

Answer 2

您可以使用sharedPreference存儲的整數變量初始設置爲0.更改activity start上的整數值，並根據該變量加載setContentView。

http://developer.android.com/reference/android/content/SharedPreferences.html

http://developer.android.com/guide/topics/data/data-storage.html

例如

int chooser;  // sharedPrefernce variable in your mainActivity 

//這是你的diiferent佈局

switch(chooser) { 
case 0; 
setContentView(R.layout.main0); 
break; 

case 1: 
setContentView(R.layout.main1); 
break; 
...... 
...... 

} 等活動...... ......
