java - GridView.minHeight does not work for small item counts -


i use markup:

<gridview         android:id="@+id/gvblock0"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:background="@color/solitude"         android:gravity="center"         android:minheight="120dp"         android:numcolumns="2"         android:stretchmode="columnwidth"         tools:layout_height="120dp"         tools:listitem="@layout/list_item_block"/>

if have 3 items (40dp height per row) have 2 rows , 80dp height. if change android:layout_height=120dp, have 120dp height expected.

but want use minheight. why doesn't work?

from gridview source code, seems not support minheight attribute.

you can fix 1 of following:

1) create minheightgridview custom class extends gridview , fix issue adding following override code example:

@override protected void onmeasure(int widthmeasurespec, int heightmeasurespec) {     super.onmeasure(widthmeasurespec, heightmeasurespec);     // after gridview measured everything, see if height needs update     int desiredheight = getmeasuredheight();     desiredheight = math.max(desiredheight, getsuggestedminimumheight());     setmeasureddimension(getmeasuredwidth(), desiredheight); }

2) encapsulate gridview inside container view - container view have minheight. make sure set background , gravity needed on container view, example: 

<framelayout     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:background="@color/solitude"     android:minheight="120dp">     <gridview         android:id="@+id/gvblock0"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:gravity="center"         android:numcolumns="2"         android:stretchmode="columnwidth"         tools:layout_height="120dp"         tools:listitem="@layout/list_item_block"/> </framelayout>

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
