Android ListView - add dynamic row to row -


in listview have 3 row types, txt, img, sms. each 1 has different row layout , works fine this:

... extends baseadapter ...  public view getview(int position, view convertview, viewgroup parent) {      textviewholder textviewholder = null;     imageholder imageholder = null;     smsholder smsholder = null;     //placeholder placeholder = null;      conversionmodel conversion = getitem(position);     int type = conversion.type;      if (convertview == null) {          if(type == conversionmodel.txt) {             textviewholder = new textviewholder();              convertview = minflater.inflate(r.layout.convers_txt,  null);             textviewholder.textview = (textview)convertview.findviewbyid(r.id.row_txt);              convertview.settag(textviewholder);         }        if(type == conversionmodel.img) {             imageholder = new imageholder();              convertview = minflater.inflate(r.layout.convers_img,  null);             imageholder.img = (imageholder)convertview.findviewbyid(r.id.row_txt);              convertview.settag(textviewholder);         }        ....     }     ...    }

my purpose this:

-alllist----------- ----txt------------ ----img------------ -----(multipledata) //placeholder must has dynamic rows in --------button----- --------button----- ---sms------------- .....

my placeholder must has dynamic rows in because don't know numbers of data comes server. tried nested listview shows first data in list.

also put linearlayout placeholder , added items this(pseudo):

for data in datas {    button btn = new button(ctx)    ...    placeholder.layout.addview(btn); }

but whenever scroll listview, getview method messing , it's rendering same buttons 10-20 times, when should 2-3.

how can achieve this? looked @ app sources telegram couldn't found similar approaches.

solution:

string arr[] = conversion.message.split(pattern.quote("$$"));   linearlayout layholder = new linearlayout(ctx);   (int = 0; < arr.length; i++) {       button test_btn = new button(ctx);       //placemodel pm = new placemodel(arr[i]);       layholder.addview(test_btn);  }    placeholder.linearlay.removeallviews(); //<-   placeholder.linearlay.addview(layholder);

add linear layout in child layout this:(for demo have added 1 button in odd child , 2 buttons in child position)

    ...         <!--main linear layout contnet-->     <textview         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:id="@+id/textview" />      <linearlayout         android:id="@+id/layout"         android:orientation="vertical"         android:layout_width="fill_parent"         android:layout_height="wrap_content" />

and add buttons in it:

in getview()

 ...                 linearlayout layout = (linearlayout)   view.findviewbyid(r.id.layout);     //important line    layout.removeallviews();     if (position % 2 == 0)         {             button b1 = new button(_context);             b1.settext("b1");             layout.addview(b1);         }         else         {             button b1 = new button(_context);             b1.settext("b1");             layout.addview(b1);             button b2 = new button(_context);             b2.settext("b2");             layout.addview(b2);         }
