In android Textview arabic text is not displaying properly it is breaking a word into alphabets. Is there any library or another way to resolve this issue?
推荐答案
您可以使用波斯语类来做到这一点.
you can use Farsi Class to do this.
import android.content.Context;
import android.graphics.Typeface;
public final class Farsi {
public static boolean isFarsiConversionNeeded = true;
private final static String szLamAndAlef = Character
.toString((char) 0xfedf)
+ Character.toString((char) 0xfe8e); // Lam + Alef
private final static String szLamStickAndAlef = Character
.toString((char) 0xfee0)
+ Character.toString((char) 0xfe8e); // Lam (Sticky !!!)+
// Alef
private final static String szLa = Character.toString((char) 0xfefb); // La
private final static String szLaStick = Character.toString((char) 0xfefc); // La
// (Sticky!!!)
private final static String szLamAndAlefWoosim = Character
.toString((char) 0xe1)
+ Character.toString((char) 0xbb); // Lam + Alef
private final static String szLamStickAndAlefWoosim = Character
.toString((char) 0x90)
+ Character.toString((char) 0xbb); // Lam (Sticky !!!)+
// Alef
private final static String szLaWoosim = Character.toString((char) 0xd9); // La
private final static String szLaStickWoosim = Character
.toString((char) 0xd9); // La
// (Sticky!!!)

}
并致电:
Typeface tf = Farsi.GetFarsiFont(this);
MyTextView.setTypeface(tf);
MyTextView.setText(Farsi.Convert("سلام"));
在资产文件夹中也需要TAHOMA.TTF"
you need TAHOMA.TTF" in assets folder too
有关更多信息，请参见此链接
for more info see this link
如果您不想在应用程序中添加字体，请使用
if you don't want add font to your application just use
MyTextView.setText(Farsi.Convert("سلام"));
