我正在寻找一个看起来像的textview。我使用下面的代码来实现这个..
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);
这是跨度中使用的样式..
<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>
除了目标文本跨度的间距,即小数部分重力... 之外,一切看起来都很好。我尝试了所有的xml属性。请帮忙

我破解了它。我发布这个,因为它可能对其他人有帮助,并感谢@kcoppock提示。
我扩展了MetricAffectingSpan
类,这会影响字符级文本格式,改变字符的宽度或高度扩展此类。
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);
}}
使用它来更新视图中的文本..
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);
