I have a viewpager with 5 fragment that handle the fragment view by TabLayout. all of them are in activity and i want when the second tablayout selected the activity's textview's text changes and also two of my control's Visibility should be Gone.
this is what i did for viewpager:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_page);
tf = Typeface.createFromAsset(getAssets(), "IRANSans_Bold.ttf");
context=this;
/*if(UIHelper.check_screenSize(this, Configuration.SCREENLAYOUT_SIZE_SMALL))
{
FloatingActionButton fab=(FloatingActionButton)UIHelper.getInstance(this,R.id.fav_GetAddress, Tags.fab);
fab.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
}*/
Display display=getWindowManager().getDefaultDisplay();
int height=display.getHeight();
tabCustomization();
/*changeTabsFont();*/
setupTabIcons();
tabLayout.getTabAt(0).getIcon().setColorFilter(Color.parseColor("#f6fda6"), PorterDuff.Mode.SRC_IN);
linearLayout=(LinearLayout)tabLayout.getTabAt(0).getCustomView();
ImageView firstTab=(ImageView)linearLayout.getChildAt(0);
firstTab.setColorFilter(Color.parseColor("#f6fda6"), PorterDuff.Mode.SRC_IN);
fav_GetAddress();
}
/* @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Toast.makeText(this,"get Activity camera result",Toast.LENGTH_LONG).show();
}*/
