how to make the method onWindowFocusChanged(boolean) to true(or call) in one tabs of tablayout in android..
Explanation:
In tablayout onWindowFocusChanged() called automatically in default activity (true), But when we click/touch on to the next tab ( which call another activity)
not able to call the onWindowFocusChanged() !!!!!! how to call onWindowFocusChanged() in second tab?
source code:
public class TabTestActivity extends TabActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Resources res = getResources();
TabHost tabHost = getTabHost();
TabHost.TabSpec spec;
Intent intent;
// Create an Intent to launch an Activity for the tab (to be reused)
intent = new Intent().setClass(this, TabOne.class);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("TabOne").setIndicator("TabOne",
res.getDrawable(R.drawable.ic_tab_One))
.setContent(intent);
tabHost.addTab(spec);
// Do the same for the other tabs
intent = new Intent().setClass(this, TabTwo.class);
spec = tabHost.newTabSpec("TabTwo").setIndicator("TabTwo",
res.getDrawable(R.drawable.ic_tab_az))
.setContent(intent);
tabHost.addTab(spec);
//tabHost.setCurrentTab(2);
}
public void onWindowFocusChanged(boolean hasFocus) {
// TODO Auto-generated method stub
Toast.makeText(this, ""+hasFocus , Toast.LENGTH_LONG).show();
super.onWindowFocusChanged(hasFocus);
}
}
-----------------------------------------------------------------------------------------------------
public class TabOne extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView textview = new TextView(this);
textview.setText("This is the Coll tab");
setContentView(textview);
}
@Override
public void onWindowFocusChanged(boolean hasFocus) {
// TODO Auto-generated method stub
Toast.makeText(this, "On window One"+hasFocus , Toast.LENGTH_LONG).show();
super.onWindowFocusChanged(hasFocus);
}
}
--------------------------------------------------------------------------
public class TabTwo extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView textview = new TextView(this);
textview.setText("This is the Coll tab");
setContentView(textview);
}
@Override
public void onWindowFocusChanged(boolean hasFocus) {
// TODO Auto-generated method stub
Toast.makeText(this, "On window TabTwo"+hasFocus , Toast.LENGTH_LONG).show();
super.onWindowFocusChanged(hasFocus);
}
}
TabTwo’s (2ndTab) onWindowFocusChanged not called while TabTwo activity runs please give the solution.
I tried to provide tabHost.setFocusable(true); I doesn’t worked!!!
Tabs are basically deprecated. You should use fragments instead. This will clearly handle your issue.
See: https://stackoverflow.com/questions/9714650/converting-tabactivity-into-fragmentactivity for an example of how to do this.
