我已经实现了自定义TextView,然后我需要更改其文本大小以供将来使用.在那一步,我决定使用style.xml和attr.xml进行textSize自定义

但是,当我的自定义布局膨胀时,我收到运行时错误.与我为了自定义而更改的部件相关的错误.

这是我实现的代码片段.

attr.xml

styles.xml

?attr/right_detail_text_size

layout_field_detailed.xml

android:id="@+id/layout_fielddetailed_textview_rightdetail"

style="@style/TextViewRightDetail" />

layout_implementation.xml

xmlns:iattr="http://schemas.android.com/apk/res-auto"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="vertical">

android:id="@+id/fieldlayoutdetailed_example"

android:layout_width="match_parent"

android:layout_height="wrap_content"

iattr:right_detail_text_size="16sp"/>

FieldLayoutDetailed.java

public FieldLayoutDetailed(Context context,AttributeSet attrs) {

super(context,attrs);

TypedArray array = context.obtainStyledAttributes(attrs,R.styleable.FieldLayout,0);

LayoutInflater.from(context).inflate(R.layout.layout_field_deailed,this,true);

我在运行时遇到的错误

现在我通过动态更改文本大小来解决问题,但我很好奇问题的原因.

谢谢.
