android - How to add custom layout to linear layout in scrollView dynamicaly -


i want show screen text area vertically scrolling , image area horizontally scrolling. have created 2 layouts:

activity_display.xml  <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical"     tools:context=".mainactivity" >      <scrollview         android:id="@+id/displaysv1"         android:layout_width="match_parent"         android:layout_height="200dp"         android:layout_marginbottom="20dp">          <linearlayout             android:id="@+id/displayll1"             android:layout_width="wrap_content"             android:layout_height="match_parent"             android:orientation="vertical">         </linearlayout>      </scrollview>      <horizontalscrollview         android:id="@+id/displaysv2"         android:layout_width="match_parent"         android:layout_height="200dp"         android:layout_marginbottom="20dp">          <linearlayout             android:id="@+id/displayll2"             android:layout_width="wrap_content"             android:layout_height="match_parent"             android:orientation="horizontal">         </linearlayout>     </horizontalscrollview>  </linearlayout>

and custom_layout.xml : want add custom layout in linear layout displayll1.

<framelayout     android:layout_width="match_parent"     android:layout_height="wrap_content"     xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/customframe">      <textview         android:layout_width="150dp"         android:layout_height="wrap_content"         android:id="@+id/customtv1"         android:layout_gravity="start|top"         android:layout_marginstart="10dp"         android:layout_marginleft="10dp"         android:text="test text"         android:layout_margintop="5dp" />      <textview         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:id="@+id/customtv2"         android:layout_gravity="top|center_horizontal"         android:text="test value"         android:layout_margintop="5dp" />      <button         style="?android:attr/buttonstylesmall"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="edit"         android:id="@+id/editbutton"         android:layout_gravity="right|top" /> </framelayout>

display activity calls: 

super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_display); linearlayout linearlayout2 = (linearlayout) findviewbyid(r.id.displayll2); for(int = 0; < count1; i++)             {                 linearlayout linearlayout = (linearlayout) findviewbyid(r.id.displayll1);                 framelayout custlayout = (framelayout) findviewbyid(r.id.customframe);                 textview label = (textview) findviewbyid(r.id.customtv1);                 textview value = (textview) findviewbyid(r.id.customtv2);                  label.settext("test");                 value.settext("test");                 linearlayout.addview(custlayout);             }              (int x = 0; x < count2; x++)             {                 final imageview image = new imageview(this);                 image.setbackgroundresource(r.drawable.ic_launcher);                 linearlayout2.addview(image);             }

i able populate image part if text part commented out. above code nothing displayed on screen. idea might going wrong? thank you!

probably have nullpointerexception.

because there no customtv1 , customtv2 ids in activity xml, calling findviewbyid(r.id.customtv1); return null value, , label.settext("test"); throw nullpointerexception.

actually calling framelayout custlayout = (framelayout) findviewbyid(r.id.customframe); not add custom xml activity one, need inflate it.

try code:

linearlayout linearlayout = (linearlayout) findviewbyid(r.id.displayll1); linearlayout linearlayout2 = (linearlayout) findviewbyid(r.id.displayll2);  layoutinflater inflater = layoutinflater.from(youractivity.this);      for(int = 0; < count1; i++){      view custlayout= inflater.inflate(r.layout.custom_layout, null, false);     textview label = (textview) custlayout.findviewbyid(r.id.customtv1);     textview value = (textview) custlayout.findviewbyid(r.id.customtv2);      label.settext("test");     value.settext("test");     linearlayout.addview(custlayout); }  (int x = 0; x < count2; x++){   imageview image = new imageview(this);   image.setbackgroundresource(r.drawable.ic_launcher);   linearlayout2.addview(image); }

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
