List View item is not gettting wrap content height using `ArrayAdapter`

ListView item is not getting wrap content height as I need to show only
I tried to set dynamic height to item but it's not working.
Please provide other solutions.

String in it's item. I am using ArrayAdapter and here is the code of TextView that I am using for inflating the item. Thank you

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/text1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:ellipsize="none"
android:gravity="center_vertical"
android:paddingBottom="@dimen/dp2"
android:paddingTop="@dimen/dp2"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:textColor="@color/white" />

I am trying to set ListView's items height using below code - 

 for (int itemPos = 0; itemPos < numberOfItems; itemPos++) {
            View item = arrayAdapter.getView(itemPos, null, listView);
            LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
            item.setLayoutParams(layoutParams);
            item.measure(item.getMeasuredWidth(), item.getMeasuredHeight());
            totalItemsHeight += item.getMeasuredHeight();
        }

Put

android:layout_height="wrap_content"

on your TextView cell layout. Should change the TextView height dinamically based on their content.

Delete this two lines:

LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
item.setLayoutParams(layoutParams);

And do you have your for code onCreate() or onStart()? because if it's onCreate it's probably that getMeasuredHeigh() returns 0 always.

Try to give some hardcoded value and check if it works instead of wrap content or just rebuild the project and try again with wrap_content

Try to change as below:

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/text1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:ellipsize="none"
    android:gravity="center_vertical"
    android:paddingBottom="@dimen/dp2"
    android:paddingTop="@dimen/dp2"
    android:textAppearance="?android:attr/textAppearanceListItemSmall"
    android:textColor="@color/white" />
