Android：在TabHost中對齊中心圖像

Question

我做了一個自定義的TabHost，我只想要在每個選項卡上沒有文字的圖像。我怎樣才能調整我的圖片選項卡的中心？請幫忙嗎？謝謝。這是MI java代碼： JAVA

private void cargarTabHost() { 

     tabs=(TabHost)findViewById(android.R.id.tabhost); 
    tabs.setup(); 

    TabHost.TabSpec spec = tabs.newTabSpec("mitab1"); 
    spec.setContent(R.id.tab1); 
    spec.setIndicator("", getResources().getDrawable(R.drawable.borrar)); 
    tabs.addTab(spec); 

    spec = tabs.newTabSpec("mitab2"); 
    spec.setContent(R.id.tab2); 
    spec.setIndicator("PLANO"); 
    tabs.addTab(spec); 

    tabs.setCurrentTab(0); 

    RelativeLayout.LayoutParams rllp = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT); 
    rllp.addRule(RelativeLayout.CENTER_IN_PARENT); 

    for (int i = 0; i < tabs.getTabWidget().getTabCount(); i++) { 
     tabs.getTabWidget().getChildAt(i).getLayoutParams().height = 75; 
     tabs.getTabWidget().getChildAt(i).findViewById(android.R.id.title). 
     setLayoutParams(rllp); 
    } 

    TabWidget tw = (TabWidget)tabs.findViewById(android.R.id.tabs); 

      View tabView = tw.getChildTabViewAt(0); 
    tabView.setBackgroundResource(Modulo.cargarColorPestanas(perfilObj.getColor())); 

    View tabView2 = tw.getChildTabViewAt(1); 
    tabView2.setBackgroundResource(Modulo.cargarColorPestanas(perfilObj.getColor())); 

    tabs.setOnTabChangedListener(new OnTabChangeListener() { 
     @Override 
     public void onTabChanged(String tabId) { 

      ... 
     } 
    }); 
}

嘗試這樣做，我還沒有嘗試過，但希望它的工作原理。

... 
for (int i = 0; i < tabs.getTabWidget().getTabCount(); i++) { 
     tabs.getTabWidget().getChildAt(i).getLayoutParams().height = 75; 
     tabs.getTabWidget().getChildAt(i).findViewById(android.R.id.title) 
     .setVisibility(View.GONE); 
    } 
...
