android - Optimal way to handle a large list of Textviews -

i have make in xml:

at moment have this:

<scrollview xmlns:android="http://schemas.android.com/apk/res/android" xmlns:pixlui="http://schemas.android.com/apk/com.neopixl.pixlui" android:id="@+id/scroll_view" android:layout_width="match_parent" android:layout_height="match_parent">  <linearlayout     android:id="@+id/container"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="vertical">      <include         layout="@layout/view_general_properties"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:layout_margintop="15dp" />      <include         layout="@layout/view_property_interior_properties"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:layout_margintop="15dp" />  </linearlayout> </scrollview> 

this view_general_properties:

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:paddingleft="12dp" android:paddingright="12dp">  <textview     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:singleline="true"     android:text="@string/general_properties"     android:textallcaps="true"     android:textsize="@dimen/title_fontsize" />  <linearlayout     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="horizontal">      <textview         style="@style/property_detail_label_style"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="0.66"         android:text="@string/total_living_area" />      <textview         style="@style/property_detail_label_style"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="0.33"         android:text="220 m²" />  </linearlayout>  <linearlayout     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="horizontal">      <textview         style="@style/property_detail_label_style"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="0.66"         android:text="@string/number_of_fronts" />      <textview         style="@style/property_detail_label_style"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="0.33"         android:text="1" />  </linearlayout>  <linearlayout     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="horizontal">      <textview         style="@style/property_detail_label_style"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="0.66"         android:text="@string/number_of_accommodation_units" />      <textview         style="@style/property_detail_label_style"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="0.33"         android:text="2" />  </linearlayout>  <linearlayout     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="horizontal">      <textview         style="@style/property_detail_label_style"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="0.66"         android:text="@string/number_of_floors" />      <textview         style="@style/property_detail_label_style"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="0.33"         android:text="4" />  </linearlayout>  <linearlayout     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="horizontal">      <textview         style="@style/property_detail_label_style"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="0.66"         android:text="@string/condition_of_the_building" />      <textview         style="@style/property_detail_label_style"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="0.33"         android:text="uitstekend" />  </linearlayout>  <linearlayout     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="horizontal">      <textview         style="@style/property_detail_label_style"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="0.66"         android:text="@string/frontage_street" />      <textview         style="@style/property_detail_label_style"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="0.33"         android:text="6m" />  </linearlayout>  <linearlayout     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="horizontal">      <textview         style="@style/property_detail_label_style"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="0.66"         android:text="@string/year" />      <textview         style="@style/property_detail_label_style"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="0.33"         android:text="1902" />  </linearlayout>  </linearlayout> 

this works fine, since have lot of duplicate code wondering if there better solution scenario.

thanks!

there many ways in can improved.

trivially, common style attributes each textview can pulled out style. see developer docs styles , themes.

i'd go further, , create separate layout resource file 1 single line of content, containing 2 textviews. leave out text values, assign id values each textview.

my_list_item.xml

<?xml version="1.0" encoding="utf-8"?> <linearlayout     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="horizontal">     <textview         style="@style/property_detail_label_style"         android:id="@+id/label"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="0.66" />     <textview         style="@style/property_detail_label_style"         android:id="@+id/value"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_weight="0.33" /> </linearlayout> 

then, in code, manually inflate 1 of these each data item, , add list dynamically.

view item;  ( /* each data item in list */ ) {     item = inflater.inflate(r.layout.my_list_item, containerview, true);     textview label = (textview) item.findviewbyid(r.id.label);     textview value = (textview) item.findviewbyid(r.id.value);     label.settext(dataitem.label);     value.settext(dataitem.value); } 

where containerview outer linearlayout holds list.
