我正在创建一个应用程序，我想将自定义文本字体设置为所有文本View。当我尝试运行应用程序时，我收到以下错误。我也包含了代码。请仔细研究。

试试这个对我有用 -
package com.example.customviews;
import android.content.Context;
import android.util.AttributeSet;
import android.widget.TextView;
public class CustomTextView extends TextView {
public CustomTextView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
setTypeface(Utils.getTypeFace(context));
}
public CustomTextView(Context context, AttributeSet attrs) {
super(context, attrs);
setTypeface(Utils.getTypeFace(context));
}
public CustomTextView(Context context) {
super(context);
setTypeface(Utils.getTypeFace(context));
}
}
public class Utils {
public static Typeface getTypeFace(Context context) {
return Typeface.createFromAsset(context.getAssets(),"Arail.ttf");
}
在yor xml中 -
<com.example.customviews.CustomTextView
android:id="@+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
答案 1 :(得分：0)
你可以这样做......
<resources>
<style name="MyFont" parent="@android:style/TextAppearance.Medium">
<item name="android:layout_width">wrap_content</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:textColor">your_color</item>
<item name="android:typeface">name of your_custom font</item>
</style>
答案 2 :(得分：0)
它为我工作
Textiew textView = (TextView) toolbar.findViewById(R.id.toolbar_title);
Typeface typeFace =Typeface.createFromAsset(getAssets(),Constants.TYPEFACE_SOLAIMAN_LIPI);
textView.setTypeface(typeFace);
textView.setText(getString(R.string.welcome));
setSupportActionBar(toolbar);
答案 3 :(得分：0)
是的，有反思。这有效：
import java.lang.reflect.Field;
import android.content.Context;
import android.graphics.Typeface;
public final class FontsOverride {
public static void setDefaultFont(Context context,
String staticTypefaceFieldName, String fontAssetName) {
final Typeface regular = Typeface.createFromAsset(context.getAssets(),
fontAssetName);
replaceFont(staticTypefaceFieldName, regular);
}
protected static void replaceFont(String staticTypefaceFieldName,
final Typeface newTypeface) {
try {
final Field staticField = Typeface.class
.getDeclaredField(staticTypefaceFieldName);
staticField.setAccessible(true);
staticField.set(null, newTypeface);
} catch (NoSuchFieldException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
}
}
然后，您需要重载几个默认字体，例如在应用程序类：
中public final class Application extends android.app.Application {
@Override
public void onCreate() {
super.onCreate();
FontsOverride.setDefaultFont(this, "DEFAULT", "MyFontAsset.ttf");
FontsOverride.setDefaultFont(this, "MONOSPACE", "MyFontAsset2.ttf");
FontsOverride.setDefaultFont(this, "SERIF", "MyFontAsset3.ttf");
FontsOverride.setDefaultFont(this, "SANS_SERIF", "MyFontAsset4.ttf");
}
}
当然，如果你使用相同的字体文件，你可以改进它只加载一次。
但是我倾向于覆盖一个，说“MONOSPACE”，然后设置一个样式来强制该字体字体应用程序：
<resources>
<style name="AppBaseTheme" parent="android:Theme.Light">
</style>
<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
<item name="android:typeface">monospace</item>
</style>
API 21 Android 5.0 我已经在评论中调查了它不起作用的报告，它似乎与主题android：Theme.Material.Light不兼容。
如果该主题对您不重要，请使用较旧的主题，例如：
<style name="AppTheme" parent="android:Theme.Holo.Light.DarkActionBar">
<item name="android:typeface">monospace</item>
</style>
