在我的 listView 中更改字体

Question

所以我的这个 listView 让我很头疼。它运行良好，但我似乎无法更改 lV 中文本的字体。

这是我的代码：

public class MyActivity3 extends Activity {
private TextView tv;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_my3);
    Button m = (Button) findViewById(R.id.button3);
    tv = (TextView) findViewById(R.id.textViewcat);
    Typeface typeface = Typeface.createFromAsset(getAssets(), "BebasNeue Bold.ttf");
    tv.setTypeface(typeface);


    String listArray[] = new String[] { "India", "England", "Canada",
            "New zealand", "South Africa", "Pakistan", "West indies" };
    int icon[] = new int[] { R.drawable.ic_launcher, R.drawable.ic_launcher,
            R.drawable.ic_launcher, R.drawable.ic_launcher,
            R.drawable.ic_launcher, R.drawable.ic_launcher,
            R.drawable.ic_launcher };

    ListView listView = (ListView) findViewById(R.id.listView);
    List<HashMap<String, String>> aList = new ArrayList<HashMap<String, String>>();

    for (int i = 0; i <= listArray.length - 1; i++) {

        HashMap<String, String> hm = new HashMap<String, String>();
        hm.put("title", listArray[i]);
        hm.put("icon", Integer.toString(icon[i]));
        aList.add(hm);
    }

    String[] sfrm = { "title", "icon" };
    int[] sto = { R.id.title, R.id.list_image};

    SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), aList,
            R.layout.row_layout, sfrm, sto);



    listView.setAdapter(adapter);

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View view,
                                int position, long id) {

            switch (position) {

                case 0:
                    Toast.makeText(getApplicationContext(), "",
                            Toast.LENGTH_SHORT).show();
                    break;
                case 1:
                    Toast.makeText(getApplicationContext(), "",
                            Toast.LENGTH_SHORT).show();
                    break;
                case 2:
                    Toast.makeText(getApplicationContext(), "",
                            Toast.LENGTH_SHORT).show();
                    break;
                case 3:
                    Toast.makeText(getApplicationContext(), "",
                            Toast.LENGTH_SHORT).show();
                    break;
                case 4:
                    Toast.makeText(getApplicationContext(), "",
                            Toast.LENGTH_SHORT).show();
                    break;
                case 5:
                    Toast.makeText(getApplicationContext(), "",
                            Toast.LENGTH_SHORT).show();
                    break;
                case 6:
                    Toast.makeText(getApplicationContext(), "",
                            Toast.LENGTH_SHORT).show();
                    break;

            }

        }
    });
}

@Override
public void onBackPressed() {
    super.onBackPressed();
    overridePendingTransition(R.anim.animation8, R.anim.animation7);
    }
}

row_layout.xml：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="5dip" >


<LinearLayout
    android:id="@+id/thumbnail"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_marginRight="5dip"
    android:padding="3dip" >

    <ImageView
        android:id="@+id/list_image"
        android:layout_width="50dip"
        android:layout_height="50dip"
        android:src="@drawable/ic_launcher" />
</LinearLayout>



<TextView
    android:id="@+id/title"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerVertical="true"
    android:layout_toRightOf="@+id/thumbnail"
    android:text="Country name"
    android:textColor="#FFFFFF"
    android:textSize="30sp"
    android:typeface="sans" />

</RelativeLayout>

这就是我的代码，你可以看到有一个 id 为“title”的文本视图。如何更改标题的字体？如果您根据我的代码回答问题，我真的很感激，因为我已经尝试了所有其他解决方案，但没有成功

Answer 1

这里是问题的详细解释。

基本上对你来说，因为它在一个列表视图中，我建议你创建自定义文本视图。将字体文件放在 assets 文件夹中很重要。

说您尝试了所有其他来源都没有成功是错误的，因为上面的链接看起来像第二个谷歌搜索结果并且工作正常。

嗨，克里斯蒂亚诺，

我想我找到了您更改字体的问题。

At your code:
Typeface typeface = Typeface.createFromAsset(getAssets(), "BebasNeue Bold.ttf");
tv.setTypeface(typeface);

Change like below and try out:
Typeface typeface = Typeface.createFromAsset(getAssets(), "customfont.ttf");
tv.setTypeface(typeface);

请将 ttf 文件名更改为任何小写字母且字母之间没有空格的名称，然后试一试即可。

Answer 3

您必须创建一个自定义适配器，并在 getView 方法中，将字体放到您的视图中：

public class ListAdapter extends ArrayAdapter<Item> {

public ListAdapter(Context context, int textViewResourceId) {
    super(context, textViewResourceId);
}

public ListAdapter(Context context, int resource, List<Item> items) {
    super(context, resource, items);
}

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

    View v = convertView;

    if (v == null) {

        LayoutInflater vi;
        vi = LayoutInflater.from(getContext());
        v = vi.inflate(R.layout.itemlistrow, null);

    }
    TextView tv = (TextView) v.findViewById(R.id.tv_name);
    tv.setTypeface(typeFace);
    ...
}

试试这个方法，希望能帮助你解决问题。

public class MyActivity3 extends Activity {
    private TextView tv;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my3);
        Button m = (Button) findViewById(R.id.button3);
        tv = (TextView) findViewById(R.id.textViewcat);
        Typeface typeface = Typeface.createFromAsset(getAssets(), "BebasNeue Bold.ttf");
        tv.setTypeface(typeface);


        String listArray[] = new String[] { "India", "England", "Canada",
                "New zealand", "South Africa", "Pakistan", "West indies" };
        int icon[] = new int[] { R.drawable.ic_launcher, R.drawable.ic_launcher,
                R.drawable.ic_launcher, R.drawable.ic_launcher,
                R.drawable.ic_launcher, R.drawable.ic_launcher,
                R.drawable.ic_launcher };

        ListView listView = (ListView) findViewById(R.id.listView);
        ArrayList<HashMap<String, String>> aList = new ArrayList<HashMap<String, String>>();

        for (int i = 0; i <= listArray.length - 1; i++) {

            HashMap<String, String> hm = new HashMap<String, String>();
            hm.put("title", listArray[i]);
            hm.put("icon", Integer.toString(icon[i]));
            aList.add(hm);
        }
//
//        String[] sfrm = { "title", "icon" };
//        int[] sto = { R.id.title, R.id.list_image};
//
//        SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), aList,
//                R.layout.row_layout, sfrm, sto);


        listView.setAdapter(new CustomAdapter(this,aList));
