安卓選項卡布局與查看傳呼機

Question

我使用選項卡布局與查看傳呼機包含4個選項卡，我的問題是，如何在選項卡上設置onLongClickListener，然後重命名它？ 在此先感謝。

Answer 1

爲onLongClickListener

View tabView= mTabHost.getTabWidget().getChildAt(i); 
// set the tag information at the view of the tab (the tag contains the position number of the tab) 
tabView.setTag(Integer.valueOf(i)); 
tabView.setOnLongClickListener(new OnLongClickListener() { 

      @Override 
      public boolean onLongClick(View v) { 
       // TODO Auto-generated method stub 
       // I print the number position of the tab 
       Log.d("tab number", ((Integer)view.getTag()).toString()); 
       return false; 
      } 
     }); 

爲重命名選項卡

((TextView)((RelativeLayout)getTabWidget().getChildAt(tabIndex)).getChildAt(textIndex)).setText("NewTabText"); 

Answer 2

try like this. 

private void changeTabsText() { 

    ViewGroup vg = (ViewGroup) tabLayout.getChildAt(0); 
    int tabsCount = vg.getChildCount(); 
    for (int j = 0; j < tabsCount; j++) { 
     ViewGroup vgTab = (ViewGroup) vg.getChildAt(j); 
     int tabChildsCount = vgTab.getChildCount(); 
     for (int i = 0; i < tabChildsCount; i++) { 
      View tabViewChild = vgTab.getChildAt(i); 
      if (tabViewChild instanceof TextView) { 
       ((TextView) tabViewChild).setText("your Text"); 
      } 
     } 
    } 
}
