所有android:id=@+id/imageTitle都给了我属性值expected errorXML的主要问题是所有视图都有两个冗余属性
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:layout_width=”wrap_content”
android:layout_height=”wrap_content”
应删除前两行。我还建议对不同的视图使用不同的ID。如果删除前两行,则会出现错误,提示应定义布局高度和宽度。如果我使用不同的ID,我仍然会出错
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:layout_width=”wrap_content”
android:layout_height=”wrap_content”
