java - SetAdapter for arrayadapter is crashing -
my app keeps crashing whenever setadapter function gets called , have no idea why, can help? emulator running says app has stopped unexpectedly.
this main
public class mainactivity extends activity { private listview listview1; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); ride ride_data[] = new ride[] { new ride("la trip", "la man"), new ride("sd trip", "sd man"), new ride("sf trip", "sf man") }; rideadapter adapter = new rideadapter(this, r.layout.listview_item_row,ride_data); listview1 = (listview)findviewbyid(r.id.listview1); view header = (view)getlayoutinflater().inflate(r.layout.listview_header_row, null); listview1.addheaderview(header); listview1.setadapter(adapter); } } and adapter
public class rideadapter extends arrayadapter<ride>{ context context; int layoutresourceid; ride data[] = null; public rideadapter(context context, int layoutresourceid, ride[] data) { super(context,layoutresourceid,data); this.context = context; this.layoutresourceid = layoutresourceid; this.data = data; } @override public view getview(int position, view convertview, viewgroup parent) { view row = convertview; rideholder holder = null; if(row == null) { layoutinflater inflater = ((activity)context).getlayoutinflater(); row = inflater.inflate(layoutresourceid, parent, false); holder = new rideholder(); holder.ridename = (textview)row.findviewbyid(r.id.txtridename); holder.personname = (textview)row.findviewbyid(r.id.txtpersonname); row.settag(holder); } else { holder = (rideholder)row.gettag(); } ride ride = data[position]; holder.ridename.settext(ride.ridename); holder.personname.settext(ride.personname); return row; } public static class rideholder { textview ridename; textview personname; } } this ride class
public class ride { public string ridename; public string personname; public ride() { } public ride(string ridename, string personname) { super(); this.ridename=ridename; this.personname=personname; } } and list item view
<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:padding="10dp" > <textview android:id="@+id/txtridename" android:layout_width ="wrap_content" android:layout_height="fill_parent" android:gravity="center_horizontal" /> <textview android:id="@+id/txtpersonname" android:layout_width ="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal" /> </linearlayout> any appreciated!
<textview android:id="@+id/txtridename" android:layout_width ="wrap_content" android:layout_height="fill_parent" android:gravity="center_horizontal" /> <textview android:id="@+id/txtpersonname" android:layout_width ="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal" /> textview should textview not textview.
you should learn read crash in logcat.
