I created a tab host in activity_main.xml that includes two tabs eg: tab1 and tab2
that includes two xml files namely tab1.xml and tab2.xml
Both the tabs has been included in mainactivity.java.

TabHost mytabhost=(TabHost)findViewById(R.id.tabhost);
mytabhost.setup();

TabSpec spec1=mytabhost.newTabSpec("HHU");
spec1.setContent(R.id.settings);
spec1.setIndicator("HHU",getResources().getDrawable(R.drawable.hhu));
TabSpec spec2=mytabhost.newTabSpec("Smart Plug");
spec2.setIndicator("Smart Plug",getResources().getDrawable(R.drawable.smartplud_tab));
spec2.setContent(R.id.control);

mytabhost.addTab(spec1);
mytabhost.addTab(spec2);

In my mainactivity.java , setcontentview(R.id.main).

setContentView(R.layout.activity_main);

In tab1.xml i have a Imagebutton with id 'btn_add'.When i click this Imagebutton i need to generate a textview dynamically in the same tab1.xml from mainactivity.java instead of activity_main.xml

IamgeButton add_btn=(ImageButton)findViewById(R.id.btn_add);
add_btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view)
{
linearlayout = new LinearLayout(getApplicationContext());
LayoutParams LLParams = new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
linearlayout.setLayoutParams(LLParams);
TextView txt_roomDetails=new TextView(getApplicationContext());

txt_roomDetails.setText("abcdefghi");
linearlayout.addView(txt_roomDetails);

setContentView(linearlayout);
}
});


I know if I give "getApplicationContext()" that will be created in activity_main.xml.........But i need in tab1.xml just below btn_add without using any intent.Please help....any solutions
