Android: How to start another activity after all views shown

Vote count:

0

I have a stub activity with progress bar and two labels, and another activity, that may do heavy task (initialize sqlite db from xml resources at first start).

I need start second activity after progress bar and labels are shown.

I'm trying

stubLayout.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {
        if (progress.getHeight() <= 0 || progress.getWidth() <= 0) return;
        if (label1.getHeight() <= 0 || label1.getWidth() <= 0) return;
        if (label2.getHeight() <= 0 || label2.getWidth() <= 0) return;

        stubLayout.getViewTreeObserver().removeOnGlobalLayoutListener(this);

        Intent intent = new Intent();
        intent.setClass(getApplicationContext(), SongListActivity.class);
        startActivity(intent);
    }
});

But I see empty screen while heavy activity is starting. What am I doing wrong?
