I am just trying to display a list from an array that I have in my arrays.xml
. When I try to run it in the emulator, I get a force close message.
If I define the array in the java file
String[] testArray = new String[] {"one","two","three","etc"};
it works, but when I use
String[] testArray = getResources().getStringArray(R.array.testArray);
it doesnt work.
Here is my Java file:
package com.xtensivearts.episode.seven;
import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
public class Episode7 extends ListActivity {
String[] testArray = getResources().getStringArray(R.array.testArray);
/** Called when the activity is first created. */
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Create an ArrayAdapter that will contain all list items
ArrayAdapter<String> adapter;
/* Assign the name array to that adapter and
also choose a simple layout for the list items */
adapter = new ArrayAdapter<String>(
this,
android.R.layout.simple_list_item_1,
testArray);
// Assign the adapter to this ListActivity
setListAdapter(adapter);
}
}
Here is my arrays.xml
file
<?xml version="1.0" encoding="utf-8"?>
<resources>
<array name="testArray">
<item>first</item>
<item>second</item>
<item>third</item>
<item>fourth</item>
<item>fifth</item>
</array>
</resources>
You can't initialize your testArray
field this way, because the application resources still aren't ready.
Just change the code to:
package com.xtensivearts.episode.seven;
import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
public class Episode7 extends ListActivity {
String[] mTestArray;
/** Called when the activity is first created. */
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Create an ArrayAdapter that will contain all list items
ArrayAdapter<String> adapter;
mTestArray = getResources().getStringArray(R.array.testArray);
/* Assign the name array to that adapter and
also choose a simple layout for the list items */
adapter = new ArrayAdapter<String>(
this,
android.R.layout.simple_list_item_1,
mTestArray);
// Assign the adapter to this ListActivity
setListAdapter(adapter);
}
}
