Moving from one activity to another takes a long time

Within my application I could notice that each time I went from one activity to another it took a long time (1 second or more), when it should be almost instantly. I did the test on my own cell phone and it takes about 2 seconds. I tested on a newer (more powerful) one, it takes less but still takes longer than it should.
I don't know if my activities are very loaded or if I am calling them in the wrong way.
Call to activities from my MainActivity:

I removed all the 'include' and used a single ViewStub to load the layouts depending on which one the user wanted to see.
Main_container.xml:
<ViewStub
android:id="#+id/viewStub"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
MainActivity:
viewStub = findViewById(R.id.viewStub);
viewStub.setLayoutResource(R.layout.home_layout);
viewStub.inflate();

How to limit ListView to particular number of list items?

I am working on a functionality in which I have a ListView and I want listView to show only 3 items. I have set ListView height to "wrap_content" and in adapter I have set get count to 3 so that it will show only 3 items but it is showing only 1 item. I am not able to figure out what is happening.My API is returing only 3 items but not able to show all the items in ListView.
Adapter Code:
public class Adapter3Testimonials extends BaseAdapter {
private Activity activity;
private ArrayList<HashMap<String, String>> data;
private static LayoutInflater inflater = null;
private Context context;
public Adapter3Testimonials(Activity a, ArrayList<HashMap<String, String>> d) {
activity = a;
this.data = d;
context = a;
inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public int getCount() {
return data.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(final int position, View convertView, ViewGroup parent) {
View itemView = inflater.inflate(R.layout.item_3_testimonials, parent, false);
TextView txtTestimonial = (TextView) itemView.findViewById(R.id.txtAdvisorTestimonails);
Log.e("TAG", "item_3_testimonials: " + position);
HashMap<String, String> testimonialsList;
testimonialsList = new HashMap<String, String>();
testimonialsList = data.get(position);
txtTestimonial.setText(testimonialsList.get("description"));
return itemView;
}
}

Inside this code I have ListView with id "listCustomer_testimonial".

Never use ListView inside Scrollview. But if you must use ListView inside ScrollView create a scrollhandler.
public class scrollhandler {
public static void getListViewSize(ListView myListView) {
ListAdapter myListAdapter = myListView.getAdapter();
if (myListAdapter == null) {
//do nothing return null
return;
}
//set listAdapter in loop for getting final size
int totalHeight = 0;
int rowheight=56;
for (int size = 0; size < myListAdapter.getCount(); size++) {
View listItem = myListAdapter.getView(size, null, myListView);
listItem.measure(0, 0);
totalHeight += listItem.getMeasuredHeight();
rowheight=listItem.getMeasuredHeight();
}
//setting listview item in adapter
ViewGroup.LayoutParams params = myListView.getLayoutParams();
params.height = totalHeight + (myListView.getDividerHeight() * (myListAdapter.getCount() - 1));
myListView.setLayoutParams(params);
// print height of adapter on log
Log.i("height of listItem:", String.valueOf(totalHeight)+","+myListAdapter.getCount());
}
}
Then lastly bind the ListView with the Handler
lv.setAdapter(adapter);
scrollhandler.getListViewSize(lv);

Your problem is not with the getCount() method or list items count.
You have used listview inside scrollview, so only one item will be visible and others can be seen on scroll.
You can use custom Listview to avoid issue in height of listview,
public class NonScrollableListview extends ListView {
public NonScrollableListview(Context context) {
super(context);
}
public NonScrollableListview(Context context, AttributeSet attrs) {
super(context, attrs);
}
public NonScrollableListview(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int heightMeasureSpec_custom = MeasureSpec.makeMeasureSpec(
Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, heightMeasureSpec_custom);
ViewGroup.LayoutParams params = getLayoutParams();
params.height = getMeasuredHeight();
}
}
In your xml ,
<com.yourpack.NonScrollableListview
android:id="#+id/list_detail"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
Or use NestedScrollView with RecyclerView instead of listview.
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:fillViewport="true">
<!--otherviews-->
<android.support.v7.widget.RecyclerView
android:id="#+id/list_detail"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<!--otherviews-->
</android.support.v4.widget.NestedScrollView>

Recyclerview items unable scroll down.inside tabpane

used tabpane take 120dp height in top.

Shared elements in fragments dont work, textview -> edittext

I have 2 fragments, and want to do a shared element transition between them.
The item in an recyclerview, with an adapter, contains a textview that should be animated to an edittext in the next fragment.
The recyclerview is in an fragment too.
Here's my code:
item layout for viewholder from adapter:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/row_container"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:background="#FAFAFA"
android:elevation="0dp"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="?android:attr/selectableItemBackground"
android:elevation="0dp"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="5dp"
android:elevation="0dp"
>
<RelativeLayout
android:layout_width="40dp"
android:layout_height="40dp"
android:background="#null"
android:elevation="0dp"
android:layout_centerVertical="true"
>
<ImageButton
android:id="#+id/notify_btn"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/ic_bookmark_black_24dp"
android:background="#null"
android:tint="#9E9E9E"
android:layout_centerInParent="true"
/>
</RelativeLayout>
<TextView

android:textStyle="bold"
android:textColor="#android:color/black"
android:layout_alignParentTop="true"
android:maxLines="1"

<TextView

android:src="#drawable/ic_star_black_24dp"
/>
</RelativeLayout>
MyAdapter class, the item row click:
row.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Fragment frag = new Fragment_Notice();
int tin_title = Integer.parseInt(String.valueOf(title.getText().length()));
if ( (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) &&
( SharedPrefHelper.getBool("shared_transition") == true) &&
( tin_title >= 1 ) ) {
//Exit transition for old fragment
frag.setSharedElementReturnTransition(TransitionInflater.from(context).inflateTransition(R.transition.title_transform));
frag.setExitTransition(TransitionInflater.from(context).inflateTransition(android.R.transition.explode));
//Enter transition for new fragment
frag.setSharedElementEnterTransition(TransitionInflater.from(context).inflateTransition(R.transition.title_transform));
frag.setEnterTransition(TransitionInflater.from(context).inflateTransition(android.R.transition.explode));
ft.replace(R.id.container, frag, "NoticeTag")
.addToBackStack(null)
.addSharedElement(title, "title")
.commit();
} else {
int open = R.anim.abc_fade_in;
int close = R.anim.abc_fade_out;
ft.setCustomAnimations(open, close, open, close)
.replace(R.id.container, frag, "NoticeTag")
.addToBackStack(null)
.commit();
}
}
});
Layout from final fragment:

android:layout_alignParentRight="true"
android:layout_centerVertical="true"

</RelativeLayout>
</LinearLayout>

android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:gravity="top"
android:id="#+id/snackbar">
</android.support.design.widget.CoordinatorLayout>
The textview doesnt animate to an edittext.
The explode animation appears.
Between activities the animation works.
Any suggestions how to fix?

GridView does not expand

I am kinda new in android and got such a problem, I am trying to use ExpandableHeightGridView for gridview inside scrollview, but layout doesn't render, some advice please.
It always gives me this error:
Exception raised during rendering: ScrollView can host only one direct child
ExpandableHeightGridView.class:
public class ExpandableHeightGridView extends GridView {
boolean expanded = false;
public ExpandableHeightGridView(Context context)
{
super(context);
}
public ExpandableHeightGridView(Context context, AttributeSet attrs)
{
super(context, attrs);
}
public ExpandableHeightGridView(Context context, AttributeSet attrs,
int defStyle)
{
super(context, attrs, defStyle);
}
public boolean isExpanded()
{
return expanded;
}
#Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
// HACK! TAKE THAT ANDROID!
if (isExpanded())
{
// Calculate entire height by providing a very large height hint.
// View.MEASURED_SIZE_MASK represents the largest height possible.
int expandSpec = MeasureSpec.makeMeasureSpec(MEASURED_SIZE_MASK,
MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);
ViewGroup.LayoutParams params = getLayoutParams();
params.height = getMeasuredHeight();
}
else
{
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
public void setExpanded(boolean expanded)
{
this.expanded = expanded;
} }

This problem is discussed here.
Try adding one more LinearLayout inside your ScrollView as a direct child and put all other layouts/controls inside of the new LinearLayout.
