listview - Android Simple ToDo list app not rendering correctly -
am following tutorial here on creating simple todo list app: http://www.mydroid.apnafundaz.com/2010/07/todolist-application-in-android-step-by-step-guide-with-screen-shots/
have completed , have no errors, app doesn't appear in example, rather looks - edittext appears, there's no listview previous tasks...
as there's no errors, it's rather hard work out i'm going wrong, partner's doing same tutorial , has come same result, thinking there issue tut - advice appreciated!
just in case, here's java file:
package com.example.helloworld; import java.util.arraylist; import android.r.string; import android.app.activity; import android.os.bundle; import android.view.keyevent; import android.view.view; import android.view.view.onkeylistener; import android.widget.arrayadapter; import android.widget.edittext; import android.widget.listview; public class helloworld extends activity { /** called when activity first created. */ @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); // inflate view setcontentview(r.layout.main); // references ui widgets listview mylistview = (listview)findviewbyid(r.id.mylistview); final edittext myedittext = (edittext)findviewbyid(r.id.myedittext); // create array list of todo items final arraylist<string> todoitems = new arraylist<string>(); // create array adaptor bind array listview final arrayadapter<string> aa; aa = new arrayadapter<string>(this, android.r.layout.simple_list_item_1, todoitems); // bind array adapter listview mylistview.setadapter(aa); myedittext.setonkeylistener(new onkeylistener(){ public boolean onkey(view v, int keycode, keyevent event){ if(event.getaction() == keyevent.action_down) if(keycode == keyevent.keycode_dpad_center) { todoitems.add(0,myedittext.gettext().tostring()); aa.notifydatasetchanged(); myedittext.settext(""); return true; } return false; } } ); } } and here's main.xml:
<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <edittext android:id="@+id/myedittext" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="new item" /> <listview android:id="@+id/mylistview" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </linearlayout>
do 1 small change, in edittext setting android:layout_height="fill_parent". cannot see list view. change wrap_content
<edittext android:id="@+id/myedittext" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="new item" />
