android - ListView in SlidingUpPanel is not scrollable -

i use library, https://github.com/umano/androidslidinguppanel, , put listview inside, not work, no scrolling, why? not listview, entire layout not roll, nor textview, nor image, nothing. here xml code:

<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"     tools:context=".detalhe_linha"       <com.sothree.slidinguppanel.slidinguppanellayout         android:id="@+id/sliding_layout"         android:layout_width="match_parent"         android:layout_height="match_parent">      <linearlayout      android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical">      <textview         android:id="@+id/textview1"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_gravity="center"         android:text="próximo onibûs sai ponto final em" />      <textview         android:id="@+id/txtprox"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="x minutos"         android:layout_gravity="center"         android:textappearance="?android:attr/textappearancelarge" />      <gridview         android:id="@+id/tabelahorarios"         android:layout_width="315dp"         android:layout_height="match_parent"         android:layout_x="0dp"         android:layout_y="123dp"         android:layout_gravity="center"         android:numcolumns="3" >      </gridview> </linearlayout>          <linearlayout             android:layout_width="match_parent"             android:layout_height="match_parent"             android:background="#cccc"             android:orientation="vertical">                <textview                 android:layout_width="match_parent"                 android:layout_height="34dp"                 android:gravity="center|bottom"                 android:text="itinerário"                 android:textsize="16sp" />              <textview                 android:id="@+id/brought_by"                 android:layout_width="match_parent"                 android:layout_height="34dp"                 android:gravity="center|top"                 android:text="arraste para cima"                 android:textsize="14sp"                 android:autolink="web" />                  <textview                 android:id="@+id/itinerarios"                 android:layout_width="match_parent"                 android:layout_height="match_parent"                 android:gravity="center|top"                 android:text=""                 android:textsize="17sp"                 android:autolink="web" />          </linearlayout>      </com.sothree.slidinguppanel.slidinguppanellayout> </linearlayout> 

by way, sorry bad english.

i found issue slidinguppanellayout intercepts touch events (onintercepttouchevent). solutions rewriting (or overriding) method isdragviewhit checked in case motionevent.action_down , can potentially cancel intercepting given touch event.

here solution cancels intercepting if panel expanded allowing click/scroll expanded child panel. means can't slide down expanded panel. implemented collapsing of panel on button click. check implementation , give ideas possible.

private boolean isdragviewhit(int x, int y) {     if(isexpanded()){         //don't intercept touch if panel expanded         return false;     }     else{         //original implementation - allow dragging on mdragview         view v = mdragview != null ? mdragview : mslideableview;         if (v == null) return false;         int[] viewlocation = new int[2];         v.getlocationonscreen(viewlocation);         int[] parentlocation = new int[2];         this.getlocationonscreen(parentlocation);         int screenx = parentlocation[0] + x;         int screeny = parentlocation[1] + y;         return screenx >= viewlocation[0] && screenx < viewlocation[0] + v.getwidth() &&                 screeny >= viewlocation[1] && screeny < viewlocation[1] + v.getheight();     } }
