选中选项卡时更改其TextSize

Question

选中时，是否可以更改Tabwidget中TextView的文本大小？

Answer 1

是的，这是一个例子：

public class MainActivity extends TabActivity {

static TabHost mytabs;


mytabs = getTabHost();

    mytabs.setOnTabChangedListener(new OnTabChangeListener() {
        @Override
        public void onTabChanged(String arg0) {         
            Log.i("TAG", "Im currently in tab with index: " + mytabs.getCurrentTab());
            TabWidget tw = (TabWidget)tabHost.findViewById(android.R.id.tabs);
            View tabView = tw.getChildTabViewAt(mytabs.getCurrentTab());
            TextView tv = (TextView)tabView.findViewById(android.R.id.title);
            // Changing textSize.
            tv.setTextSize(20);
        }       
    });
