Question

我正在学习一个教程，一切都很顺利，直到我尝试添加图片。

在发布代码之前，这就是我正在使用的内容：

eclipse与android附加组件建立目标：2.2 api 8 avd目标：2.2 api 8

在教程中，我被告知在res中制作我自己的drawable文件夹，所以我做了并在文件夹中有3个.pngs。是的我尝试使用drawable-hdpi文件夹，但仍然出现此错误：

“抱歉，申请等等等异常停止。请再试一次。”

这是我的xml代码：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/LinearLayoutVert"
android:layout_width="wrap_content"
android:layout_height="125dp"
android:background="@layout/activity_postage_calculator"
android:gravity="center|left|top"
android:orientation="vertical"
android:paddingTop="5dp"
tools:context=".PostageCalculator" >

<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:paddingBottom="10dp"
    android:text="@string/package_type"
    android:textColor="@android:color/black"
    android:textSize="20sp" />

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/LinearLayoutHoriz1"
    android:layout_width="320dp"
    android:layout_height="wrap_content"
    android:gravity="center" >

    <RadioButton
        android:id="@+id/radioButton1"
        android:layout_width="100dp"
        android:layout_height="60dp"
        android:text="@string/letter" />
</LinearLayout>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/LinearLayoutHoriz2"
    android:layout_width="320dp"
    android:layout_height="wrap_content"
    android:gravity="center" >

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:contentDescription="@string/letter"
        android:src="@drawable/letter" />
      </LinearLayout>
  </LinearLayout>

我是新手，所以你们可以给我的任何东西都会非常感激

Answer 1

异常说明：二进制XML文件行＃1：无效的可绘制标记LinearLayout 。

您是否将布局文件（您发布的XML）放在res / drawable目录中？如果是这样，请尝试将其移动到res / layout目录。

Answer 2

错误表示找不到资源。

检查文件名是否与您在XML上调用的名称相同。并确保文件的名称全部为小写。
