[android-developers] ListView problem

[sisko]

In following a tutorial from "SAMS Android Application Development in
24 hours" I hit a problem with my first ListView example.

Basically, my java code is firing according to log messages I set but
my ListView does not display when I execute my app. The App runs fine
without crashing so syntactically all seems to be well.

Since I can't attach documents, please bear with me as I paste some
code but you can download the entire sample app from
http://www.icerge.com/android-sample-app-download

My layout file is called Menu.xml and is as below:
<?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">

<RelativeLayout
        android:id="@+id/RelativeLayout01"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">
        <ImageView
                android:id="@+id/ImageView01"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentLeft="true"
                android:layout_alignParentTop="true"
                android:src="@drawable/quizicon">
        </ImageView>
        <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_centerHorizontal="true"
                android:layout_alignParentTop="true"
                android:textColor="@color/menuxmlTitleColor"
                android:textSize="@dimen/menuxmlTitleSize"
                android:id="@+id/menuxmlTitle"
                android:text="@string/menuxmlTitleText">
        </TextView>
        <ImageView
                android:id="@+id/ImageView02"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentTop="true"
                android:layout_alignParentRight="true"
                android:src="@drawable/quizicon">
        </ImageView>
</RelativeLayout>



<RelativeLayout
        android:id="@+id/RelativeLayout02"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">
        <ListView
                android:layout_height="wrap_content"
                android:layout_above="@+id/ImageView03"
                android:layout_width="fill_parent"
                android:layout_alignParentTop="true"
                android:id="@+id/ListView_Menu"
                android:layout_centerVertical="false">
        </ListView>
        <ImageView
                android:id="@+id/ImageView03"
                android:layout_alignParentBottom="true"
                android:scaleType="fitEnd"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent">
        </ImageView>
</RelativeLayout>

</LinearLayout>


The java file is called QuizMenuActivity.java and is as follows:
package com.androidbook.triviaquiz;

import android.os.Bundle;
import android.util.Log;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class QuizMenuActivity extends QuizActivity {
        private final String LOGID      =       "Track";
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.menu);

        Log.i(LOGID, "Begining!");

        ListView menuList       =       (ListView)
findViewById(R.id.ListView_Menu);
        /*String[] items                =
{ getResources().getString(R.string.menu_item_play),
                                                                
getResources().getString(R.string.menu_item_scores),
                                                                
getResources().getString(R.string.menu_item_settings),
                                                                
getResources().getString(R.string.menu_item_help) };*/
        String[] items          =        {"test#1","test#2","test3","test#4"} ;
        ArrayAdapter<String> adapt      =       new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, items);
        menuList.setAdapter(adapt);


        Log.i(LOGID, "Reaching this point!");
    }
}

Finally, there is a Menu_item.xml which defines my TextView that the
java file above attempts to write array data to. It is as follows:
<TextView
        android:id="@+id/TextView01"
        android:layout_height="wrap_content"
        xmlns:android="http://schemas.android.com/apk/res/android";
        android:layout_width="match_parent"
        android:text="testing testing"
        android:layout_gravity="center_horizontal"
        android:shadowRadius="5"
        android:gravity="center"
        android:textColor="@color/listview_items_color"
        android:shadowDx="3"
        android:shadowDy="3"
        android:textSize="@dimen/menuxml_item_size"
        android:shadowColor="@color/listview_items_color_glow">
</TextView>

As I don't want to overwhelm you with code you will have to take my
word for it that all the resources are in place and are not the
problem.


Can anyone offer some insight? Please download the app from

better and see what I mean.

Thanks.
