根据设备大小增加字体大小 [英] Increase the font size based on the size of the device

问题描述

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.

Questions :

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.

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

3. Any Flaws in using this kind of approach ?

Xml for the text view

<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>

Thanks in advance

Yes, this approach is flawed. Android devices have different sizes, but they can also have very different densities as well.

You should just be following the Android design best practices.

They're actually very well thought out. Why would you want to reinvent the wheel?
