customlistviewadapter.java custom list adapter file

and xml file holds listview design

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" > <imageview android:id="@+id/imgthumbnail" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignparentleft="true" android:layout_alignparenttop="true" android:src="@drawable/ic_action_call" android:layout_marginleft="10dp" android:layout_margintop="2dp"/> <textview android:id="@+id/txttitle" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_aligntop="@+id/imageview1" android:layout_torightof="@+id/imageview1" android:text="large text" android:layout_marginleft="60dp" android:layout_margintop="6dp"/> <textview android:id="@+id/txtsubtitle" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignbottom="@+id/imageview1" android:layout_alignleft="@+id/textview1" android:layout_below="@+id/textview1" android:text="" /> <imageview android:id="@+id/imageview2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignparentright="true" android:layout_below="@+id/textview1" android:src="@drawable/arrow" /> </relativelayout>

looking log cat, error seems because theme used not compat. check manifest, , create sure utilize compat theme.

example (for acitivities in apps) :

<application //other code android:theme="@style/theme.appcompat.light" >

or if utilize action bar on particular activity :

<activity //other code android:theme="@style/theme.appcompat.light" >

tips :

always pay attending log cat, caused by. know problem there.
