Apps TableLayout declared in XML, not found in code.

Heya!

This has started to do my head in, and I can't figure this out.

After many searches on google, i found several examples of how to programmatically/dynamically add rows to a TableLayout.

My customers.xml file.

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:stretchColumns="0,1"
                android:id="@+id/customers_table" >
</TableLayout>

My CustomersActivity.java:

setContentView(R.layout.customers);

later on:

TableLayout tl = (TableLayout)findViewById(R.id.customers_table);

My AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.crmdeskapp"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="10" />

    <application
        android:icon="@drawable/ic_tab_support"
        android:label="@string/app_name" >
        <activity android:name=".CustomersActivity" android:label="@string/app_name"
          android:theme="@android:style/Theme.NoTitleBar"
          android:screenOrientation="landscape">
          <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
          </intent-filter>
                
    	</activity>
    	<activity android:name =".CustomerActivity">
    	  
    	</activity>
    </application>
    <uses-permission android:name="android.permission.INTERNET"></uses-permission>
</manifest>

Now, for some weird reason "findViewById" returns null. This is frustrating as hell since "customers_table" TableLayout is declared RIGHT THERE.

Am i missing something? Newbie here.

Where do you call setContentView(R.layout.customers)?

You should make sure to call it in the acitivity's onCreate() method.

It is indeed called from activity's onCreate() method:

public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.customers);

Right. I think i found the source of my problem. Orientation.

I started experimenting with orientations, and layouts for these. Apparently, the "customers.xml" had to be identical (or the name of the layout atleast, had to be identical). Problem solved.

.....i think It runs atleast.
