I am trying to add skeleton layouts/effect to my viewpager, but due to some issue, the shimmer layout loads and right after i see a white screen instead of . viewpager data content.
I am currently using the libraries :
implementation 'com.ethanhua:skeleton:1.1.2'
implementation 'io.supercharge:shimmerlayout:2.1.0'
Here's my code :
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/white"
android:paddingTop="64dp"
>
<View
android:id="@+id/roomsTitle"
style="@style/Headline2LeftBlack"
android:layout_width="match_parent"
android:layout_height="240dp"
android:layout_marginStart="16dp"
android:layout_marginEnd="16dp"
android:layout_gravity="center_vertical"
android:background="@color/black_12"
android:text="@string/meeting_rooms"
android:textAppearance="@style/TextAppearance.Text.Chronicle"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
android:paddingBottom="16dp"/>
<View
android:id="@+id/room1"
android:layout_width="match_parent"
android:layout_height="240dp"
android:clipToPadding="false"
android:overScrollMode="never"
android:layout_marginStart="16dp"
android:layout_marginEnd="16dp"
android:layout_marginTop="16dp"
android:paddingBottom="16dp"
android:background="@color/black_12"
app:layout_constraintTop_toBottomOf="@id/roomsTitle" />
<View
android:id="@+id/room2"
android:layout_width="match_parent"
android:layout_height="240dp"
android:clipToPadding="false"
android:overScrollMode="never"
android:layout_marginStart="16dp"
android:layout_marginEnd="16dp"
android:layout_marginTop="16dp"
android:background="@color/black_12"
app:layout_constraintTop_toBottomOf="@id/room1" />
</android.support.constraint.ConstraintLayout>
The above code is my layout for skeleton view. The code below is my viewpager code in activity : public class RoomListsActivity extends BaseActivity implements RoomListsMvpView {
@Inject
RoomListsPagerAdapter mPagerAdapter;
@BindView(R.id.room_lists_view_pager)
ViewPager mViewPager;
@BindView(R.id.tab_layout)
TabLayout mTabLayout;
private SkeletonScreen skeletonScreen;
public static Intent getStartIntent(Context context) {
return new Intent(context, RoomListsActivity.class);
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_room_lists);
getActivityComponent().inject(this);
setUnBinder(ButterKnife.bind(this));
mPresenter.onAttach(this);
setUp();
}
@Override
protected void setUp() {
setSupportActionBar(mToolbar);
if (getSupportActionBar() != null) {
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_backarrow);
getSupportActionBar().setElevation(0);
getSupportActionBar().setDisplayShowTitleEnabled(false);
}
mViewPager.setAdapter(mPagerAdapter);
mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(mTabLayout));
mTabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
mViewPager.setCurrentItem(tab.getPosition());
TextView text = (TextView) tab.getCustomView();
if (text != null) {
text.setTypeface(null, Typeface.BOLD);
text.setTextColor(ContextCompat.getColor(RoomListsActivity.this, R.color.reddish));
}
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
TextView text = (TextView) tab.getCustomView();
if (text != null) {
text.setTypeface(null, Typeface.NORMAL);
text.setTextColor(ContextCompat.getColor(RoomListsActivity.this, R.color.brownish_grey));
}
}
@Override
public void onTabReselected(TabLayout.Tab tab) { }
});
mRefresh.setOnRefreshListener(this::refreshassistant);
mPresenter.getAvailableRooms();
}
@Override
protected void onDestroy() {
mPresenter.onDetach();
super.onDestroy();
}
@Override
public void showRooms(List<RoomList> roomLists) {
int selectedTab = mTabLayout.getSelectedTabPosition();
mPagerAdapter.setRooms(roomLists);
if (mTabLayout.getTabCount() != roomLists.size()) {
mTabLayout.removeAllTabs();
for (int i = 0; i < roomLists.size(); i++) {
mTabLayout.addTab(mTabLayout.newTab().setText(roomLists.get(i).getRoomTitle()));
}
mViewPager.setOffscreenPageLimit(mTabLayout.getTabCount());
for (int i = 0; i < mTabLayout.getTabCount(); i++) {
TabLayout.Tab tab = mTabLayout.getTabAt(i);
if (tab != null) {
TextView tabTextView = new TextView(this);
tab.setCustomView(tabTextView);
tabTextView.getLayoutParams().width = ViewGroup.LayoutParams.WRAP_CONTENT;
tabTextView.getLayoutParams().height = ViewGroup.LayoutParams.WRAP_CONTENT;
tabTextView.setText(tab.getText());
if (i == 0) {
tabTextView.setTypeface(null, Typeface.BOLD);
tabTextView.setTextColor(ContextCompat.getColor(this, R.color.reddish));
}
}
}
if (selectedTab > 0 && selectedTab < mTabLayout.getTabCount()) {
TabLayout.Tab tab = mTabLayout.getTabAt(selectedTab);
if (tab != null) {
tab.select();
}
}
}
}
@Override
public void showLoading() {
skeletonScreen = Skeleton.bind(mViewPager)
.load(R.layout.item_skeleton_roomlist)
.duration(1000)
.color(R.color.shimmer_color)
.angle(20)
.shimmer(false)
.show();
}
@Override
public void hideLoading() {
super.hideLoading();
skeletonScreen.hide();
mRefresh.setRefreshing(false);
}
}
For some reason
{
skeletonScreen = Skeleton.bind(mViewPager)
.load(R.layout.item_skeleton_roomlist)
.duration(1000)
.color(R.color.shimmer_color)
.angle(20)
.shimmer(false)
.show();
}
is overriding my viewpager code and shows a blank white screen instead of content. Any idea how I can go about fixing this?
Thanks!
from How do I update my skeleton layout code such that it doesn't block my viewpager?
