Android EspressoTest match navigationDrawer item with position -

-

i want open navigation drawer , click specific position item code below.

private void clickmenu(int position) {     onview(withid(r.id.drawer_layout))             .perform(actionopendrawer());      ondata(is(instanceof(navdraweritem.class)))             .inadapterview(withid(r.id.navigation_list))             .atposition(position).perform(viewactions.click()); }

current shows no matches.

android.support.test.espresso.nomatchingviewexception: no views in hierarchy found matching: id: com.trumpia.android.loyaltea.debug:id/navigation_list if target view not part of view hierarchy, may need use espresso.ondata load 1 of following adapterviews:android.widget.listview{3bb66aad vfed.vc. .f...... 0,0-720,1533 #7f0f008c app:id/navigation_drawer} - android.widget.listview{22585c25 gfed.vc. ......i. 0,0-0,0 #102000a android:id/list}

or other error below

caused by: java.lang.runtimeexception: action not performed because target view not match 1 or more of following constraints: (is assignable class: class android.widget.adapterview , displayed on screen user) target view: "listview{id=2131689612, res-name=navigation_drawer, visibility=invisible, width=720, height=1533, has-focus=false, has-focusable=false, has-window-focus=true, is-clickable=true, is-enabled=true, is-focused=false, is-focusable=true, is-layout-requested=false, is-selected=false, root-is-layout-requested=false, has-input-connection=false, x=-720.0, y=0.0, child-count=5}"

it seems there inconsistent between each running. because drawer not opened? how can guarantee drawer opened?

if comment .inadapterview line then, matches 2 item below.

+--------->listview{id=16908298, res-name=list, visibility=gone, width=0, height=0, has-focus=false, has-focusable=false, has-window-focus=true, is-clickable=true, is-enabled=true, is-focused=false, is-focusable=true, is-layout-requested=true, is-selected=false, root-is-layout-requested=false, has-input-connection=false, x=0.0, y=0.0, child-count=0} ****matches**** ... +------>listview{id=2131689612, res-name=navigation_drawer, visibility=visible, width=720, height=1533, has-focus=true, has-focusable=true, has-window-focus=true, is-clickable=true, is-enabled=true, is-focused=true, is-focusable=true, is-layout-requested=false, is-selected=false, root-is-layout-requested=false, has-input-connection=false, x=-1.0, y=0.0, child-count=5} ****matches****

is there way match navigation drawer item item position? can match text item order matter in case.

well, changed adapterview's resource name r.id.navigation_drawer r.id.navigation_list. , update espresso core 2.2 2.0, works well.

private void clickmenu(int position) {     onview(withid(r.id.drawer_layout))             .perform(actionopendrawer());       ondata(is(instanceof(navdraweritem.class)))              .inadapterview(withid(r.id.navigation_drawer))             .atposition(position).perform(viewactions.click()); }

navigationdrawerfragment replaced r.id.navigation_drawer fragment mainactivity. , navigationdrawerfragment has r.id.navigation_list listview.

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
