1、我的TextView。
<TextView
android:id="@+id/tev_title"
android:layout_width="match_parent"
android:layout_height="@dimen/dp_50"
android:gravity="center"
android:text="@string/create_user"
android:textColor="@color/color_FFFFFFFF"
android:textSize="@dimen/sp_17" />
2、res下的values文件夹下的strings.xml文件的资源字符串。
<string name="created_b">创建了</string>
<string name="users_b">个用户</string>
3、TextView Style 管理类。
package com.phone.common_library.manager;
import android.content.Context;
import android.graphics.Typeface;
import android.text.Spannable;
import android.text.SpannableString;
import android.text.style.AbsoluteSizeSpan;
import android.text.style.StyleSpan;
import android.widget.TextView;
import com.phone.common_library.spannable.VerticalAlignTextSpan;
public class TextViewStyleManager {
private static final String TAG = TextViewStyleManager.class.getSimpleName();
public static void setTextViewStyle(TextView textView,
String data,
int start) {
Spannable spannable = new SpannableString(data);
// 粗体
spannable.setSpan(new StyleSpan(Typeface.BOLD), start, data.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);
// 显示
textView.setText(spannable);
}
public static void setTextViewStyle(Context context,
TextView textView,
String data,
int start,
int end,
float size) {
Spannable spannable = new SpannableString(data);
// 粗体
spannable.setSpan(new StyleSpan(Typeface.BOLD), start, end, Spannable.SPAN_INCLUSIVE_INCLUSIVE);
spannable.setSpan(new AbsoluteSizeSpan(ScreenManager.spToPx(context, size)), start, end, Spannable.SPAN_INCLUSIVE_INCLUSIVE);
// 显示
textView.setText(spannable);
}
public static void setTextViewStyleVerticalCenter(Context context,
TextView textView,
String data,
int start,
int end,
float size) {
Spannable spannable = new SpannableString(data);
// 粗体
spannable.setSpan(new StyleSpan(Typeface.BOLD), start, end, Spannable.SPAN_INCLUSIVE_INCLUSIVE);
spannable.setSpan(new AbsoluteSizeSpan(ScreenManager.spToPx(context, size)), start, end, Spannable.SPAN_INCLUSIVE_INCLUSIVE);
//SpannableString字体大小不一致垂直居中显示
spannable.setSpan(new VerticalAlignTextSpan(context, size), start, end, SpannableString.SPAN_INCLUSIVE_EXCLUSIVE);
// 显示
textView.setText(spannable);
}
}
4、在Activity中设置SpannableString多个字体大小不一致的情况下，设置字体垂直居中显示。
TextViewStyleManager.setTextViewStyleVerticalCenter(this,
tevTitle, getResources().getString(R.string.created_b)
+ 3
+ getResources().getString(R.string.users_b),
getResources().getString(R.string.created_b).length(),
getResources().getString(R.string.created_b).length() + 1,
28);
5、效果如下（见下图一，图中红圈处的3这个字最大，而且这个字水平居中显示了）。
