菜单项的android系统中更改文字大小 [英] Changing text Size of menu item in android

问题描述

我正在使用操作栏简单的菜单项，在主要活动使用以下code：

I am using simple menu items in action bar by using following code in main activity:

    package com.kaasib.ftpclient;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.app.ActionBar;


public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item){
        boolean ret;
        if(item.getItemId() == R.id.connection_manager){
            ret = true;
        }else{
            ret = super.onOptionsItemSelected(item);
        }

        return ret;
    }
}

下面是main.xml中菜单的xml：

Here is menu xml in main.xml:

    <menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:id="@+id/connection_manager"
        android:orderInCategory="100"
        android:showAsAction="collapseActionView"
        android:title="@string/connection_manager"
        android:textSize="2sp"
        />

</menu> 

这是工作，除了它不进行任何更改文字大小。眼下菜单项的文本大小较大，而我想要的字体大小小。所以我在做什么错了？不应该的android：TEXTSIZE attributute工作？还是有一些其他的方式这样做呢？我认为，文字大小应该从XML设置不从Java，因为它是设计相关的事情。任何建议？

It is working except it is not making any change to text size. Right now text size for menu item is bigger while I want font size to be smaller. So what am I doing wrong? Shouldn't android:textSize attributute work? Or is there some other way to do so? I believe that text size should be set from XML not from java as it is design related thing. Any suggestion?

推荐答案

或者你也可以在你使用的主题值/款式项目设置字体大小。在我的情况在AndroidManifest.xml文件中指示的风格是：

Or you can set the font size in the values/styles item for the theme you are using. In my case the style indicated in the AndroidManifest.xml file is:

android:theme="@style/AppTheme"

所以我对AppTheme风格是现在：

And so my style for the AppTheme is now:

<style name="AppTheme" parent="AppBaseTheme">
    <item name="android:textSize">20sp</item>
</style>

似乎有些奇怪它不会因为尽管该项目工作...

Seems strange it doesn't work for the item though...
