带有JPEG源的ImageButton会导致InflateException

标签： java android xml android-layout

我有15个imageButtons，其src属性设置为JPEG图片：

    <ImageButton
        android:id="@+id/button01"
        android:layout_width="fill_parent"
        android:layout_height="match_parent"
        android:layout_weight="0.2"
        android:padding="5dp"
        android:scaleType="fitCenter"
        android:adjustViewBounds="true"
        android:background="@drawable/button_state"
        android:src="@drawable/agri_b" />

当我运行我的应用程序时，出现InflateException错误。我尝试将Activity课改为FragmentActivity课，但没有改变。我想我的JPEG图片大小有问题。然而，我最大的图片有217 KB的大小。 这是我得到的错误：

任何帮助都将不胜感激。

修改-1

要检查错误是否与图片大小有关，我从ImageButtons删除了所有图片来源，但我意外地再次收到错误!!严重的问题在哪里？

2 个答案:

答案 0 :(得分：0)

尝试

android:layout_width="0dp"

（如果您的图像在其父视图中水平显示） 或

 android:layout_height="0dp"

（如果它们在其父级内垂直显示）。如果您正在使用layout_weight，则图片的宽度或高度应始终为0dp。

答案 1 :(得分：0)

可能是您的代码存在问题

<ImageButton
    android:id="@+id/button01"
    android:layout_width="fill_parent"
    android:layout_height="match_parent"
    android:layout_weight="0.2"
    android:padding="5dp"
    android:scaleType="fitCenter"
    android:adjustViewBounds="true"
    android:background="@android:color/transparent"
    android:src="@drawable/ic_launcher" />

尝试使用此代码..如果这有效..那么问题可能就是..你在背景和src上都设置了drawable。为什么你会收到错误..
