Android的自定義字體列表視圖

Question

我有我的android活動的自定義字體。

MainActivity.class

private void initControls() { 
    // TODO Auto-generated method stub 
    header = (TextView) findViewById (R.id.tvAccommodations); 
    lv = (ListView) findViewById (R.id.lvAccommodations); 
    text = (TextView) findViewById (R.id.textView); 

    Typeface tf = Typeface.createFromAsset(getAssets(), 
      "fonts/heartbre.ttf"); 
    header.setTypeface(tf); 
    text.setTypeface(tf); 



    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, 
        R.array.abra_hotel, R.layout.custom_list_text); 
      lv.setAdapter(adapter); 
      header.setText(value); 

custom_list_text.xml

<TextView xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/list_text" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:textSize="18sp" 
android:textStyle="bold" 
android:text="@string/app_name" 
android:paddingLeft="6dip" /> 

的Android拋出NullPointerException異常。爲什麼這樣？任何幫助表示讚賞。謝謝。

Answer 1

這裏是自定義適配器類和構造

class CustomAdapter extends ArrayAdapter<CharSequence>{ 

    Context context; 
    int layoutResourceId;  
    CharSequence data[] = null; 
    Typeface tf; 

public CustomAdapter(Context context, int layoutResourceId, CharSequence[] data, String FONT) { 
    super(context, layoutResourceId, data); 
    this.layoutResourceId = layoutResourceId; 
    this.context = context; 
    this.data = data; 
    tf = Typeface.createFromAsset(context.getAssets(), FONT); 
} 

把你想要在你的資產文件夾中使用，並填寫您的列表視圖像這樣的字體：

listAdapter = new CustomAdapter(this, R.layout.custom_list_text, R.array.abra_hotel, "name_of_font.ttf");

你不能應用字體直接ListView和你需要爲列表視圖創建自定義的適配器和更改字體爲更多詳情請點擊下面的疊後，它已經討論。
