如何在类中设置自定义文本风格

Question

我正在创建类并设置文本样式。我已经在attrs和stylable and Style中定义了，使Getter Setter和SET TEXTSTYLE BOLD仍然不会变得大胆。如何设置大胆的文本？plz帮助？

 <declare-styleable name="CustomTagGroup"> 
        <attr name="descriptionTextStyle" format="flags">
            <flag name="normal" value="0" />
            <flag name="bold" value="1" />
            <flag name="italic" value="2" />
            <flag name="bolditalic" value="3" />
        </attr>
    <style name="CustomTagGroup">
  <item name="atg_horizontalPadding">12dp</item>
        <item name="atg_verticalPadding">3dp</item>
        <item name="android:textStyle">bold</item>
        <item name="descriptionTextStyle">bolditalic</item>
    </style>

  final TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.CustomTagGroup, defStyleAttr, R.style.CustomTagGroup);
        try {
a.getType(R.styleable.CustomTagGroup_descriptionTextStyle);
            int bold = Typeface.BOLD_ITALIC;
            textStyle = a.getInt(R.styleable.CustomTagGroup_descriptionTextStyle, bold);
}catch(Exception e){
e.printStackTrace()
}

这是您的自定义类，它扩展了 textView ？如果是，则首先获得属性taht，您在XML中定义了：

<com.package.CustomTextView
 ......
 app:text_style = "1"
/>

采用属性值后，添加setbold by Dower code

@Override
    protected void onFinishInflate() {
        super.onFinishInflate();
        // set your if else condition that come from attr
        // Like you get 1 then execute below line
        this.setTypeface(getTypeface(),Typeface.BOLD);
    }
