java - Views are invisible after they was added into ViewGroup -

-

i'm adding views programatically framelayout:

public class pixelgridview extends framelayout { ...      public void addviewwithoutcoords(tableview view, int column, int row) {             float x = column * mcellsidesize;             float y = row * mcellsidesize;              framelayout.layoutparams lp = new framelayout.layoutparams(viewgroup.layoutparams.wrap_content,                         viewgroup.layoutparams.wrap_content);                 view.setlayoutparams(lp);              view.setleft(0);             view.settop(0);              view.setx(x);             view.sety(y);             view.setvisibility(visible);             addview(view);         } ... }

however, somehow invisible. getchildcount() returns count of them. getvisibility() each added view returns visible.

i can drag'n'drop such views viewgroup framelayout , when this, earlier added views become visible.

view layout file:

<relativelayout     xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent" android:layout_height="match_parent">     <imageview         android:id="@+id/ivtable"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_centerinparent="true"/>     <edittext         android:id="@+id/ivtablename"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_centerinparent="true"         android:background="@color/style_table_grey"         android:textcolor="@android:color/white"/> </relativelayout>

even if add new view without drag become visible.

the item view of framelayout , relativelayout can overlapping. if 2 item views in same positions of framelayout, first loaded item covered later item.

i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response...
