如何從聯繫人列表中顯示的名字在Android應用程序

Question

到ListView控件如何從聯繫人列表中顯示的名字在Android應用程序

Answer 1

public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 


    // We'll define a custom screen layout here (the one shown above), but 
    // typically, you could just use the standard ListActivity layout. 
    setContentView(R.layout.contacts_list_item); 

    Cursor mCursor = getContentResolver().query(Data.CONTENT_URI, 
        null,      // projection 
        null,      // selection 
        null,      // selectionArgs 
        Data.DISPLAY_NAME);   // sortOrder   

    startManagingCursor(mCursor); 



    // Now create a new list adapter bound to the cursor. 
    // SimpleListAdapter is designed for binding to a Cursor. 
    contactAdapter = new SimpleCursorAdapter(
      this, // Context. 
      android.R.layout.two_line_list_item, // Specify the row template to use (here, two columns bound to the two retrieved cursor rows). 
      mCursor, // Pass in the cursor to bind to. 
      new String[] {Data.DISPLAY_NAME},   // Array of cursor columns to bind to. 
      new int[] {android.R.id.text1}); // Parallel array of which template objects to bind to those columns. 

    // Bind to our new adapter. 
    setListAdapter(contactAdapter); 

} 

到ListView的，如果你想顯示聯繫人姓名和電話號碼都然後更改contactAdapter值as

contactAdapter = new SimpleCursorAdapter(
      this, // Context. 
      android.R.layout.two_line_list_item, // Specify the row template to use (here, two columns bound to the two retrieved cursor rows). 
      mCursor, // Pass in the cursor to bind to. 
      new String[] {Data.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER},   // Array of cursor columns to bind to. 
      new int[] {android.R.id.text1, android.R.id.text2}); // Parallel array of which template objects to bind to those columns.
