设置android textview字体,android
android-为活动中的所有textViews设置字体?
是否可以为活动中的所有TextView设置字体? 我可以使用以下命令为单个textView设置字体:
TextView tv=(TextView)findViewById(R.id.textView1);
Typeface face=Typeface.createFromAsset(getAssets(), "font.ttf");
tv.setTypeface(face);
但是我想一次更改所有textViews,而不是为每个textView手动设置它,任何信息都将不胜感激!

解决方案1 ::只需通过将父视图作为参数传递来调用这些方法。
private void overrideFonts(final Context context, final View v) {
try {
if (v instanceof ViewGroup) {
ViewGroup vg = (ViewGroup) v;
for (int i = 0; i < vg.getChildCount(); i++) {
View child = vg.getChildAt(i);
overrideFonts(context, child);
}
} else if (v instanceof TextView ) {
((TextView) v).setTypeface(Typeface.createFromAsset(context.getAssets(), "font.ttf"));
}
} catch (Exception e) {
}
}
解决方案2 ::您可以使用自定义字体将TextView类子类化,然后使用它代替textview。
public class MyTextView extends TextView {
public MyTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
public MyTextView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public MyTextView(Context context) {
super(context);
init();
}
private void init() {
if (!isInEditMode()) {
Typeface tf = Typeface.createFromAsset(getContext().getAssets(), "font.ttf");
setTypeface(tf);
}
}
}

我个人收藏中的一个:
private void setFontForContainer(ViewGroup contentLayout) {
for (int i=0; i < contentLayout.getChildCount(); i++) {
View view = contentLayout.getChildAt(i);
if (view instanceof TextView)
((TextView)view).setTypeface(yourFont);
else if (view instanceof ViewGroup)
setFontForContainer((ViewGroup) view);
}
}

如果您正在寻找更通用的编程解决方案,我创建了一个静态类,该类可用于设置整个视图的字体(活动UI)。 请注意,我正在使用Mono(C#),但是您可以使用Java轻松实现它。
您可以向此类传递要自定义的布局或特定视图。 如果您想提高效率,可以使用Singleton模式实现它。
public static class AndroidTypefaceUtility
{
static AndroidTypefaceUtility()
{
}
//Refer to the code block beneath this one, to see how to create a typeface.
public static void SetTypefaceOfView(View view, Typeface customTypeface)
{
if (customTypeface != null && view != null)
{
try
{
if (view is TextView)
(view as TextView).Typeface = customTypeface;
else if (view is Button)
(view as Button).Typeface = customTypeface;
else if (view is EditText)
(view as EditText).Typeface = customTypeface;
else if (view is ViewGroup)
SetTypefaceOfViewGroup((view as ViewGroup), customTypeface);
else
Console.Error.WriteLine("AndroidTypefaceUtility: {0} is type of {1} and does not have a typeface property", view.Id, typeof(View));
}
catch (Exception ex)
{
Console.Error.WriteLine("AndroidTypefaceUtility threw:\n{0}\n{1}", ex.GetType(), ex.StackTrace);
throw ex;
}
}
else
{
Console.Error.WriteLine("AndroidTypefaceUtility: customTypeface / view parameter should not be null");
}
}
public static void SetTypefaceOfViewGroup(ViewGroup layout, Typeface customTypeface)
{
if (customTypeface != null && layout != null)
{
for (int i = 0; i < layout.ChildCount; i++)
{
SetTypefaceOfView(layout.GetChildAt(i), customTypeface);
}
}
else
{
Console.Error.WriteLine("AndroidTypefaceUtility: customTypeface / layout parameter should not be null");
}
}
}
在您的活动中,您将需要创建一个Typeface对象。 我使用放在我的Resources / Assets /目录中的.ttf文件在OnCreate()中创建我的。 确保该文件在其属性中被标记为Android资产。
protected override void OnCreate(Bundle bundle)
{
...
LinearLayout rootLayout = (LinearLayout)FindViewById(Resource.Id.signInView_LinearLayout);
Typeface allerTypeface = Typeface.CreateFromAsset(base.Assets,"Aller_Rg.ttf");
AndroidTypefaceUtility.SetTypefaceOfViewGroup(rootLayout, allerTypeface);
}

扩展Agarwal的答案...您可以通过切换TextView的样式来设置常规,粗体,斜体等。
import android.content.Context;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.widget.TextView;
public class TextViewAsap extends TextView {
public TextViewAsap(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
public TextViewAsap(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public TextViewAsap(Context context) {
super(context);
init();
}
private void init() {
if (!isInEditMode()) {
Typeface tf = Typeface.DEFAULT;
switch (getTypeface().getStyle()) {
case Typeface.BOLD:
tf = Typeface.createFromAsset(getContext().getAssets(), "Fonts/Asap-Bold.ttf");
break;
case Typeface.ITALIC:
tf = Typeface.createFromAsset(getContext().getAssets(), "Fonts/Asap-Italic.ttf");
break;
case Typeface.BOLD_ITALIC:
tf = Typeface.createFromAsset(getContext().getAssets(), "Fonts/Asap-Italic.ttf");
break;
default:
tf = Typeface.createFromAsset(getContext().getAssets(), "Fonts/Asap-Regular.ttf");
break;
}
setTypeface(tf);
}
}
}
您可以这样创建您的Assets文件夹:
您的Assets文件夹应如下所示:
最后,您在xml中的TextView应该是TextViewAsap类型的视图。 现在它可以使用您编码的任何样式...
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Example Text"
android:textStyle="bold"/>

最佳答案
1.为一个textView设置自定义字体
Typeface typeface = Typeface.createFromAsset(getContext().getAssets(), "Fonts/FontName.ttf");
textView.setTypeface (typeface);
2.为所有textViews设置自定义字体
创建如下的Java类
public class CustomFont extends android.support.v7.widget.AppCompatTextView {
public CustomFont(Context context) {
super(context);
init();
}
public CustomFont(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public CustomFont(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init();
}
private void init() {
Typeface tf = Typeface.createFromAsset(getContext().getAssets(), "fonts/FontName.ttf");
setTypeface(tf);
}
}
并在您的xml页面中
...
/>
=>
android:id="@+id/TextView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:text="KEEP IT SIMPLE"
android:textAlignment="center" />

使用反射的“通用”方式示例:
**它提出了一个包含视图组子级方法setTextSize(int,float)的想法,但是您可以像对setTypeFace()的问题一样采用它
/**
* change text size of view group children for given class
* @param v - view group ( for example Layout/widget)
* @param clazz - class to override ( for example EditText, TextView )
* @param newSize - new font size
*/
public static void overrideTextSize(final View v, Class> clazz, float newSize) {
try {
if (v instanceof ViewGroup) {
ViewGroup vg = (ViewGroup) v;
for (int i = 0; i < vg.getChildCount(); i++) {
View child = vg.getChildAt(i);
overrideTextSize(child, clazz, newSize);
}
} else if (clazz.isAssignableFrom(v.getClass())) {
/** create array for params */
Class>[] paramTypes = new Class[2];
/** set param array */
paramTypes[0] = int.class; // unit
paramTypes[1] = float.class; // size
/** get method for given name and parameters list */
Method method = v.getClass().getMethod("setTextSize",paramTypes);
/** create array for arguments */
Object arglist[] = new Object[2];
/** set arguments array */
arglist[0] = TypedValue.COMPLEX_UNIT_SP;
arglist[1] = newSize;
/** invoke method with arguments */
method.invoke(v,arglist);
}
} catch (Exception e) {
e.printStackTrace();
}
}
警告:
使用反射应该非常小心。 反射课非常“例外”
例如,您应该检查是否存在注释,以防止出现各种不同的问题。 在方法SetTextSize()的情况下,最好检查批注android.view.RemotableViewMethod
