如何在工具栏上的溢出菜单中的菜单项上设置字体 [英] How to set a typeface to menu items in overflow menu on toolbar
问题描述
我想更改溢出菜单的各项的默认字体并设置自定义字体.
我尝试将Factory添加到LayoutInflater，并在onCreateView()方法中更改了 TextView的字体.但这没有用.这是代码(在onCreateOptionsMenu内部)，
getLayoutInflater().cloneInContext(this).setFactory(new LayoutInflater.Factory() {
@Override
public View onCreateView(String name, Context context, AttributeSet attrs) {
if (name.contains("com.android.internal.view.menu.IconMenuItemView")) {
try {
LayoutInflater li = LayoutInflater.from(context);
final View view = li.createView(name, null, attrs);
new Handler().post(new Runnable() {
@Override
public void run() {
((TextView) view).setTypeface("custom_typeface");
}
});
return view;
} catch (Exception e) {
e.printStackTrace();
}
}
return null;
}
});
实际上，当我调试代码时，它从未到达onCreateView()内部.
那该如何解决呢?
谢谢.
这就是我解决此问题的方式，
第1步:创建一个全局Factory变量，并在如下所示的onCreate()中初始化
mFactory = new LayoutInflater.Factory() {
@Override
public View onCreateView(String name, final Context context, AttributeSet attrs) {
try {
LayoutInflater li = LayoutInflater.from(context);
final View view = li.createView(name, null, attrs);
new Handler().post(new Runnable() {
@Override
public void run() {
((TextView) view.findViewById(R.id.title)).setTypeface("custom_typeface");
}
});
return view;
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
};
第2步:覆盖AppCompatActivity中的 onCreateView()方法. 请记住，有两个具有不同签名的oncreate()方法.
public View onCreateView(字符串名称，上下文上下文，AttributeSet属性)-适用于HONEYCOMB之前的应用程序
public View onCreateView(查看父级，字符串名称，上下文上下文，AttributeSet属性)-已在API 11中添加.
onCreateView的实现如下所示，
@Override
public View onCreateView(View parent, String name, Context context, AttributeSet attrs) {
if(name.contains("android.support.v7.view.menu.ListMenuItemView")) {
LayoutInflater li = LayoutInflater.from(context);
View view = null;
try {
view = li.createView(name, null, attrs);
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
if (view != null) {
if(mFactory != null) {
view = mFactory.onCreateView(name,context,attrs);
}
return view;
}
}
return super.onCreateView(name, context, attrs);
}
注意:
(1)我使用了如何为选项"菜单设置字体?
使用LayoutInflaterCompat.setFactory的Android菜单项字体
I want to change the default typeface of the items of the overflow menu and set a custom typeface.
I tried adding a Factory to the LayoutInflater and within the onCreateView() method I changed the TextView's typeface. But it didn't work. Here is the code(Inside onCreateOptionsMenu),
getLayoutInflater().cloneInContext(this).setFactory(new LayoutInflater.Factory() {
@Override
public View onCreateView(String name, Context context, AttributeSet attrs) {
if (name.contains("com.android.internal.view.menu.IconMenuItemView")) {
try {
LayoutInflater li = LayoutInflater.from(context);
final View view = li.createView(name, null, attrs);
new Handler().post(new Runnable() {
@Override
public void run() {
((TextView) view).setTypeface("custom_typeface");
}
});
return view;
} catch (Exception e) {
e.printStackTrace();
}
}
return null;
}
});
Actually when I debug the code, it never reached inside onCreateView().
So how to fix this?
Thanks.
This is how I solved this issue,
step 1: create a global Factory variable and initialized in onCreate() like below,
mFactory = new LayoutInflater.Factory() {
@Override
public View onCreateView(String name, final Context context, AttributeSet attrs) {
try {
LayoutInflater li = LayoutInflater.from(context);
final View view = li.createView(name, null, attrs);
new Handler().post(new Runnable() {
@Override
public void run() {
((TextView) view.findViewById(R.id.title)).setTypeface("custom_typeface");
}
});
return view;
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
};
Step 2: override the onCreateView() method in AppCompatActivity. remember there are 2 oncreate() methods with different signatures.
public View onCreateView (String name, Context context, AttributeSet attrs) - for pre HONEYCOMB apps
public View onCreateView (View parent, String name, Context context, AttributeSet attrs) - added in API 11.
The implementation of onCreateView is like below,
@Override
public View onCreateView(View parent, String name, Context context, AttributeSet attrs) {
if(name.contains("android.support.v7.view.menu.ListMenuItemView")) {
LayoutInflater li = LayoutInflater.from(context);
View view = null;
try {
view = li.createView(name, null, attrs);
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
if (view != null) {
if(mFactory != null) {
view = mFactory.onCreateView(name,context,attrs);
}
return view;
}
}
return super.onCreateView(name, context, attrs);
}
Note:
(1) I used android.support.v7.view.menu.ListMenuItemView instead of com.android.internal.view.menu.IconMenuItemView since I am using the AppCompat support library.
(2) Since I have already initialized a Factory object in onCreate(), I removed the code segment(posted in my question) from onCreateOptionsMenu(). So it contains only this part,
getMenuInflater().inflate(R.menu.my_menu, menu);
return true;
