[英]Set custom style to textviews inside a custom view in android
I have a custom view class DoubleTextView.java which looks like below, 我有一个自定义视图类DoubleTextView.java,如下所示,
public class DoubleTextView extends LinearLayout {
LinearLayout layout;
TextView upTextView;
TextView downTextView;
Context mContext;
public DoubleTextView(Context context) {
super(context);
mContext = context;
}
public DoubleTextView(Context context, AttributeSet attrs) {
super(context, attrs);
mContext = context;
String service = Context.LAYOUT_INFLATER_SERVICE;
LayoutInflater li = (LayoutInflater) getContext().getSystemService(service);
layout = (LinearLayout) li.inflate(R.layout.custom_double_text, this, true);
upTextView = layout.findViewById(R.id.text_up);
downTextView = layout.findViewById(R.id.text_down);
TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.DoubleTextView);
String upText = a.getString(R.styleable.DoubleTextView_upText);
String downText = a.getString(R.styleable.DoubleTextView_downText);
int upTextStyle = a.getInteger(R.styleable.DoubleTextView_styleUpText,R.style.ListOtherLightInfo);
int downTextStyle = a.getInteger(R.styleable.DoubleTextView_styleDownText,R.style.ListOtherLightInfo);
upText = upText == null ? "" : upText;
downText = downText == null ? "" : downText;
upTextView.setText(upText);
downTextView.setText(downText);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
upTextView.setTextAppearance(R.style.ListOtherLightInfo);
downTextView.setTextAppearance(downTextStyle);
}
a.recycle();
}
public DoubleTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
mContext = context;
}
}
Attributes to be set in DoubleTextView.class is below, 在DoubleTextView.class中设置的属性如下,
<declare-styleable name="DoubleTextView">
<attr name="upText" format="string"/>
<attr name="downText" format="string"/>
<attr name="styleUpText" format="reference"/>
<attr name="styleDownText" format="integer"/>
</declare-styleable>
I am unable to add custom styles to the two textviews present in my DoubleTextView.java class. 我无法将自定义样式添加到DoubleTextView.java类中存在的两个textview中。 Custom styles are present in my styles.xml 自定义样式存在于我的styles.xml中
This is how I am trying to use this, 这就是我要使用的方式
<com.loconav.common.widget.DoubleTextView
app:upText="heklow"
app:downText="askjdnakjsndjasndjkasndasndj"
app:styleUpText="@style/BoldTextBlue"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
But it is throwing error when app:styleUpText is used in xml , 但是在xml中使用app:styleUpText时,它会引发错误,
Method threw 'java.lang.UnsupportedOperationException' exception. 方法抛出“ java.lang.UnsupportedOperationException”异常。
Thanks in advance 提前致谢
使用getResourceId
代替getInteger
作为样式属性。
