Question

All I’m trying to do is open a very simple application that is supposed to do nothing but display an imageView above a textView. The application worked fine until I added the imageView so I’m assuming my problem has something to do with that.

Here is the code:

package com.isi.sa;

import android.app.Activity;
import android.os.Bundle;

public class SimpleAssessment extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.main);
    }
}

Here is my layout -> 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">

    <ImageView
        android:layout_width="fill_parent"
        android:src="@drawable/isi_logo"/>

    <TextView  
        android:layout_width="fill_parent" 
        android:layout_height="fill_parent" 
        android:text="@string/hello"
        android:background="@color/white"
        android:textColor="@color/black"/>
</LinearLayout>

When I try and run the app in Eclipse through the Emulator the emulator gives me the following error:

The application Application Name (process.com.isi.sa) has stopped unexpectedly. Please try again.

The Console log in Eclipse shows the following messages:

Thanks in advance for the help!

ImageView is missing a layout_height and you can’t have both of them as “fill_parent”. You should use a RelativeLayout or use absolute heights/widths.
