Tifinagh 字符未显示在 Android 模拟器上

Question

正如您在附图中看到的那样，Eclipse 正在正确显示资源文件中 XML 中的 Tifinagh 文本。 但是当我将此 XML 解析为 listView 时，它不会显示。我教它与 XML 解析有关，所以我基于 Hello world 教程创建了一个新项目并替换为“Hello world！”使用 Tifinagh 字符（我从 XML 中复制的）并再次使用；他们不显示。

我在 stackoverflow 上查看了similar question，但还没有答案。

所以;

1. Android 是否支持 Tifinagh？
2. 如果没有，是否有任何解决方法可以解决此问题？

感谢您的帮助。

更新

我设法通过使用以下方法在 hello world 界面中设置字体：

// Set the tifinagh font
    Typeface tf = Typeface.createFromAsset(getAssets(), "t_ircam-webfont.ttf");               
    TextView tv = (TextView) MainActivity.this.findViewById(R.id.txt);
    tv.setTypeface(tf);

但是如何为 ListView 设置它？

    package com.theopentutorials.android.activities;

import java.io.IOException;
import java.util.List;

import android.app.Activity;
import android.graphics.Typeface;
import android.os.Bundle;
import android.view.Menu;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;

import com.theopentutorials.android.beans.PostObj;
import com.theopentutorials.android.xml.XMLPullParserHandler;

public class XMLPullParserActivity extends Activity {

    ListView listView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        // Prepare the list view to publish item to.
        listView = (ListView) findViewById(R.id.list);

        List<PostObj> posts = null;
        try {
            XMLPullParserHandler parser = new XMLPullParserHandler();
            posts = parser.parse(getAssets().open("amawal_posts.xml"));

            System.out.println("============================== ");
            System.out.println("Posts fresh "+ posts);
            System.out.println("============================== ");

            ArrayAdapter<PostObj> adapter = new ArrayAdapter<PostObj>(this, R.layout.list_item, posts);
            listView.setAdapter(adapter);
        } catch (IOException e) {
            e.printStackTrace();
        }

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.xmlpull_parser, menu);
        return true;
    }

}

经过更多的试验和错误，我得到了它的工作:) 由于我将原始数据从 XML 获取到列表视图，因此我必须创建一个自定义适配器，查看完整代码：

package com.theopentutorials.android.xml;

import java.util.List;

import android.content.Context;
import android.graphics.Typeface;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;

import android.widget.TextView;

public class MyAdapter<T> extends BaseAdapter {

private final Typeface mTypeface;

private List<T> objects; // obviously don't use object, use whatever
                                // you really want

private final Context context;

public MyAdapter(Context context, int resource, List<T> objects) {//Context context, int resource, List<T> objects
    this.context = context;
    this.objects = (List<T>) objects;
    mTypeface = Typeface.createFromAsset(context.getAssets(), "t_ircam-webfont.ttf");
}

@Override
public int getCount() {
    return objects.size();
}

@Override
public Object getItem(int position) {
    return objects.get(position);
}

@Override
public long getItemId(int position) {
    return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    Object obj = objects.get(position);

    TextView tv = new TextView(context);
    tv.setTypeface(mTypeface);
    tv.setText(obj.toString()); // use whatever method you want for the
                                // label
    // set whatever typeface you want here as well
    return tv;
}
}

在我的主要活动中

public class XMLPullParserActivity extends Activity {

    ListView listView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        // Prepare the list view to publish item to.
        listView = (ListView) findViewById(R.id.list);

        List<PostObj> posts = null;
        try {
            // Parse the XML
            XMLPullParserHandler parser = new XMLPullParserHandler();
            posts = parser.parse(getAssets().open("amawal_posts.xml"));

            /*System.out.println("============================== ");
            System.out.println("Posts fresh " + posts);
            System.out.println("============================== ");*/

            listView.setAdapter(new MyAdapter<PostObj>(this, R.layout.list_item, posts));


        } catch (IOException e) {
            e.printStackTrace();
        }

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.xmlpull_parser, menu);
        return true;
    }
}

在布局/list_item.xml中

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >


</TextView>

在layout/main.xml中

    <TextView
        android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:text="@string/hello_world"
        android:textColor="#CC0033"
        android:textSize="16sp" />

    <ListView
        android:id="@+id/list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_below="@id/text" />

</RelativeLayout>
