Want To Setemptyview() Of A Listactivity
As the title suggests, I want to set a default view for a list activity. I have tried to do this : TextView emptyView = new TextView(this); emptyView.setText('No lists available');
Solution 1:
The problem is that emptyView
is never attached to anything, if you use addView()
:
TextViewemptyView=newTextView(this);
((ViewGroup) getListView().getParent()).addView(emptyView);
emptyView.setText("It's empty!");
getListView().setEmptyView(emptyView);
Now you'll see it!
I wrote a quick Runnable to alternate between empty / "full"...
publicclassExampleextendsListActivity {
@OverridepublicvoidonCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView emptyView = newTextView(this);
((ViewGroup) getListView().getParent()).addView(emptyView);
emptyView.setText("It's empty!");
getListView().setEmptyView(emptyView);
getListView().postDelayed(newRunnable() {
@Overridepublicvoidrun() {
if(getListAdapter() == null)
setListAdapter(newArrayAdapter<String>(Example.this, android.R.layout.simple_list_item_1, newString[] {"It", "Has", "Content"}));
elsesetListAdapter(null);
getListView().postDelayed(this, 2000);
}
}, 2000);
}
}
