Android TabHost how to solve the following white line, I believe that many inexperienced people do not know what to do, so this article summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

I used to use GridView and ActivityGroup to do paging. Because I think TabHost is not easy to use, there is also the reason why my level is poor. If you help, rewrite view any problem can be solved, ha ha, the following please see the implementation process, is actually very simple.

For (int I = 0; I < tabWidget.getChildCount (); iTunes +) {

/ / get the tabview entry

V = tabWidget.getChildAt (I)

/ / set tab background color

/ / get the textview control (default is white)

TextView textView = (TextView) v.findViewById (android.R.id.title)

TextView.setTextColor (Color.BLACK)

/ / default options to deal with

If (tabHost.getCurrentTab () = = I)

V.setBackgroundResource (R.drawable.renren_sdk_pay_repair_btn)

}

/ / tabchanged monitoring

TabHost.setOnTabChangedListener (new OnTabChangeListener () {

/ / tabId displays the value in newTabSpec

@ Override

Public void onTabChanged (String tabId) {

/ / initialize all view backgrounds first.

For (int I = 0; I < tabHost.getTabWidget (). GetChildCount (); iTunes +) {

View v = tabHost.getTabWidget () .getChildAt (I)

/ / set tab background color

V.setBackgroundResource (android.R.color.white)

/ / selected for processing

If (tabHost.getCurrentTab () = = I) {

V.setBackgroundResource (R.drawable.renren_sdk_pay_repair_btn)

}

}

}

});

}

}

In fact, it is the annotated part of those lines, which I believe you will understand at a glance.

Solve the method of white line under Tab:

First we need to get the paging view and textview controls for Tab, because the default font for textview is white. We have to deal with it. Get it and process it accordingly (that is, the background should be added, and the font color should be changed). * We need to OnTabChangedListener the TabHost; it is not listening. Is to use his click to execute the event.
