增加基于所述装置的尺寸的字体大小 [英] Increase the font size based on the size of the device

问题描述

予计划使用不同的字体大小在不同的设备尺寸的TextView以便使字母清晰。我已经决定不使用不同的布局，为不同的设备，并建立了一个共同的布局，以适应所有设备。现在唯一的问题是关于文字大小。

I planned to use different font size for the textview on different device size so as to make the letters legible. I have already decided not to use different layouts for different devices and built a common layout to fit in all the devices. Now the only problem is on the text size.

问题：

1. 我想就如何改变的基础上的大小（物理尺寸）的设备的字体大小的技术建议。

1. I would like to have your technical suggestions on how to alter the font size based on the size (the physical size) of the device.

如何根据宽高比导出的字体大小

How to derive the font size based on the aspect ratio.

什么破绽使用这种方法？

Any Flaws in using this kind of approach ?

XML文本视图

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ffffff"
android:orientation="vertical"  > 

                <TextView
                    android:id="@+id/tvValue4"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:text="I planned to use different font size for the textview on different device size so as to make the letters legible. I have already decided not to use different layouts for different devices and built a common layout to fit in all the devices. Now the only problem is on the text size."
                    android:textColor="#000000"  
                    android:textSize="15sp" />

</LinearLayout>

在此先感谢

推荐答案

试试这个，添加这个属性在你的XML。它会调整基于屏幕尺寸TEXTSIZE试试吧。

Try this, Add this attribute in your xml. It will adjust textsize based on screensize try it.
