tabStripEnabled for TabWidget in Older API's
Android 2.2 i.e API Level 8 has tabStripEnabled="true" for T开发者_JAVA百科abWidget how to achieve the same in Older versions of Android?
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) {}
}
I made it so:
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();
}
