问题描述
我要寻找一个TextView它看起来像。我用低于code对本实施..
I am looking for a textview which looks like . I have used below code for the implementation of this..
SpannableString text;
text = new SpannableString(bal_dollars.getText());
int index = bal_dollars.getText().toString().indexOf(".");
text.setSpan(new TextAppearanceSpan(getApplicationContext(),
R.style.HeroGraphicBalanceSmallFont), index, bal_dollars
.getText().toString().length(),
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
bal_dollars.setText(text, TextView.BufferType.SPANNABLE);
下面是跨度使用的样式..
here is the style used in the span..
<style name="HeroGraphicBalanceSmallFont" parent="@android:style/TextAppearance.Medium">
<item name="android:layout_width">wrap_content</item>
<item name="android:textSize">50sp</item>
<item name="android:singleLine">true</item>
<item name="android:layout_height">match_parent</item>
<item name="android:layout_gravity">top|right</item>
<item name="android:paddingBottom">30dp</item>
<item name="android:gravity">top|right</item>
<item name="android:textColor">@color/status_text</item>
<item name="customFont">fonts/HeroicCondensedMedium.ttf</item>
</style>
一切看起来除了文本即小数部分重力的针对性跨度间隔很好.. 。我尝试了所有的XML属性。请帮助
everything looks fine except the spacing of targeted span of text i.e decimal part gravity.. . I tried all the xml attributes. Please help
推荐答案
我破解它。我张贴这个,因为它可能是有益他人,感谢@kcoppock的提示。
我已经延长 MetricAffectingSpan
类,它影响,改变宽度或字符高度扩展的方式字符级的文本格式此类。
I cracked it. I am posting this as it might be helpful for others and thanks to @kcoppock for the hint.
I have extended MetricAffectingSpan
class which affects character-level text formatting in a way that changes the width or height of characters extend this class.
public class CustomCharacterSpan extends MetricAffectingSpan {
double ratio = 0.5;
public CustomCharacterSpan() {
}
public CustomCharacterSpan(double ratio) {
this.ratio = ratio;
}
@Override
public void updateDrawState(TextPaint paint) {
paint.baselineShift += (int) (paint.ascent() * ratio);
}
@Override
public void updateMeasureState(TextPaint paint) {
paint.baselineShift += (int) (paint.ascent() * ratio);
}}
使用这个在视图中更新文本。
use this to update the text in your views..
String string = tv.getText().toString();
SpannableString text = new SpannableString(tv.getText());
int index = tv.getText().toString().indexOf(".");
text.setSpan(new CustomCharacterSpan(), index, string.length(),
SpannableString.SPAN_EXCLUSIVE_EXCLUSIVE);//u can use ur own ratio using another constructor
tv.setText(text, TextView.BufferType.SPANNABLE);
