我要做的就是打开一个非常简单的应用程序，它应该什么都不做，只是在 textView 上方显示一个 imageView。在我添加 imageView 之前，该应用程序运行良好，所以我假设我的问题与此有关。

这是代码：

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);
    }
}

这是我的布局-> 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>

当我尝试通过模拟器在 Eclipse 中运行应用程序时，模拟器给了我以下错误：

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

Eclipse 中的控制台日志显示以下消息：

在此先感谢您的帮助！

ImageView 缺少 layout_height 并且您不能将它们都作为“fill_parent”。您应该使用 RelativeLayout 或使用绝对高度/宽度。
