在tabview中從ListActivity啓動新的ListActivity

Question

我有tabview和4個選項卡，我使用TabHost來顯示選項卡我的應用程序。 被另一個類填充每個選項卡從ListActivity延伸，這裏是代碼

public class TabbedActivity extends TabActivity { 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.tab_layout); 

    TabHost tabHost = getTabHost(); 

    // Tab for Catalog 
    TabSpec catalogspec = tabHost.newTabSpec("Catalog"); 
    catalogspec.setIndicator("Complete Catalog Fall 2012", getResources().getDrawable(R.drawable.ic_catalog)); 
    Intent catalogIntent = new Intent(this, Category.class); 
    catalogspec.setContent(catalogIntent); 
// Adding all TabSpec to TabHost 
    tabHost.addTab(catalogspec); // Adding catalog tab 
} 

，這在其他意圖

public class Category extends ListActivity { 
@Override 
public void onCreate(Bundle savedInstanceState) {  
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.list_of_data); 
Categories = new ArrayList<String>(); 
    fillListCategories(); 

    myListItems = new ArrayList<String>(); 
    adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, Categories); 
     this.setListAdapter(adapter); 
}} 

代碼在列表視圖有產品清單,,我的觀點是如何設置Onclick在同一Tab中打開另一個「ListActivity」？

Answer 1

在您的範疇類，添加一個onClickListener像這樣：

public class Category extends ListActivity { 
@Override 
public void onCreate(Bundle savedInstanceState) {  
super.onCreate(savedInstanceState); 
setContentView(R.layout.list_of_data); 
Categories = new ArrayList<String>(); 
fillListCategories(); 

myListItems = new ArrayList<String>(); 
adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, Categories); 
    this.setListAdapter(adapter); 
    this.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
    @Override 
    public void onItemClick(AdapterView<?> parent, View item, 
          int position, long id) { 
    mSelectedCategory = (String)parent.getItemAtPosition(position); 

    Intent intent = new Intent(getBaseContext(), ScreenTwo.class); 
      intent.putExtra("name", mSelectedCategory.(WHATEVER INFO YOU NEED ABOUT THE CATEGORY); 
      startActivity(intent); 
    } 
}); 
}} 

ScreenTwo.java會是什麼樣子與ListAdapter範疇類，但與通過意圖傳遞的信息：

public class ScreenTwo extends ListActivity { 
@Override 
public void onCreate(Bundle savedInstanceState) {  
super.onCreate(savedInstanceState); 
setContentView(R.layout.list_of_data); 
Bundle b = getIntent().getExtras(); 
    String Name = b.getString("name"); 
Categories = new ArrayList<String>(); 
fillListCategories(); 

myListItems = new ArrayList<String>(); 
adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, Categories); 
    this.setListAdapter(adapter); 
}}
