Question

Android 2.2 i.e API Nivel 8 tiene tabStripEnabled = "true" para TabWidget cómo lograr lo mismo en versiones anteriores de Android?

Answer 1

private void SetupTabs(TabHost tabHost) { 

    LinearLayout ll = (LinearLayout) tabHost.getChildAt(0); 
    TabWidget tw = (TabWidget) ll.getChildAt(0); 

    Field mBottomLeftStrip; 
    Field mBottomRightStrip; 

    try { 
     mBottomLeftStrip = tw.getClass().getDeclaredField("mBottomLeftStrip"); 
     mBottomRightStrip = tw.getClass().getDeclaredField("mBottomRightStrip"); 

     if (!mBottomLeftStrip.isAccessible()) { 
      mBottomLeftStrip.setAccessible(true); 
     } 

     if (!mBottomRightStrip.isAccessible()) { 
      mBottomRightStrip.setAccessible(true); 
     } 

     mBottomLeftStrip.set(tw, getResources().getDrawable(R.drawable.blank)); 
     mBottomRightStrip.set(tw, getResources().getDrawable(R.drawable.blank));// blank is the name of the image in drawable folder 

    } 
    catch (java.lang.NoSuchFieldException e) { 
     // possibly 2.2 
     try { 
      Method stripEnabled = tw.getClass().getDeclaredMethod("setStripEnabled", boolean.class); 
      stripEnabled.invoke(tw, false); 

     } 
     catch (Exception e1) { 
      e1.printStackTrace(); 
     } 
    } 
    catch (Exception e) {} 
} 

Answer 2

me hizo tan:

try { 
     Method setStripEnabled = tabWidget.getClass().getDeclaredMethod(
       "setStripEnabled", boolean.class); 
     setStripEnabled.invoke(tabWidget, true); 

     Method setLeftStripDrawable = tabWidget.getClass() 
       .getDeclaredMethod("setLeftStripDrawable", int.class); 
     setLeftStripDrawable.invoke(tabWidget, R.drawable.tab_line); 

     Method setRightStripDrawable = tabWidget.getClass() 
       .getDeclaredMethod("setRightStripDrawable", int.class); 
     setRightStripDrawable.invoke(tabWidget, R.drawable.tab_line); 
    } catch (NoSuchMethodException e) { 
     e.printStackTrace(); 
    } catch (IllegalArgumentException e) { 
     e.printStackTrace(); 
    } catch (IllegalAccessException e) { 
     e.printStackTrace(); 
    } catch (InvocationTargetException e) { 
     e.printStackTrace(); 
    }
