如何改變標籤的顏色TabHost（

默認背景是黑色的，我想它不同的顏色。我想答案是下面的XML內（但我可能是錯的）。如何改變標籤的顏色TabHost（

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android" 

    > 
    <!-- When selected --> 
    <item android:drawable="@drawable/login" 
      android:state_selected="true" 


     /> 
    <!-- When not selected --> 
    <item android:drawable="@drawable/login" 

     /> 
</selector>

這是Mainactivity

TabHost tabHost = getTabHost(); 


    // Tab for login 
    TabSpec Login = tabHost.newTabSpec("Login"); 
    // setting Title and Icon for the Tab 

    Login.setIndicator("", getApplicationContext().getResources().getDrawable(R.drawable.drawtab1)); 
    Intent LoginIntent = new Intent(this, Tab1Activity.class); 
    LoginIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
    Login.setContent(LoginIntent);

那麼你可以通過編程改變它這個樣子。

tabHost.getTabWidget().getChildAt(index).setBackgroundColor(Color.parseColor("#93BEDF"));

它爲你的先生工作？ – Remario

謝謝。對不起，它沒有 - 確定哪個索引是。 –

您試圖修改的孩子的索引。例如第一個孩子索引= 0 – Remario

變化state_selected到state_enabled 和定製tabhost背景使用這個選擇

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <!-- When selected --> 
    <item android:drawable="@drawable/login" 
     android:state_enabled="true"/> 
</selector>

和改變選擇的標籤顏色，你必須處理它編程

fragmentTabHost.setOnTabChangedListener(new TabHost.OnTabChangeListener() { 
     @Override 
     public void onTabChanged(String s) { 
      //this change previous selected tab color to default color 
      for (int i = 0; i < fragmentTabHost.getTabWidget().getChildCount(); i++) 
       fragmentTabHost.getTabWidget().getChildAt(i).setBackgroundColor(ContextCompat.getColor(getContext(), R.color.backgroundColor)); 
      //this line change selected tab color 
      fragmentTabHost.getTabWidget().getChildAt(fragmentTabHost.getCurrentTab()).setBackgroundColor(ContextCompat.getColor(getContext(), R.color.colorAccent)); 
     } 
    });
