實際應(yīng)用

在上一篇文章中只是初步識別了一下效果氧急；今天就來做一個實際應(yīng)用涣狗，拿公司的頁面來做效果.

手機上的效果圖

Pad 上的效果圖

看圖我們知道碘裕，控件按一定比例放大了，但不能變形纳令，所以上下會留有空白。
先看下我們實現(xiàn)后的效果
1.phone 1920*1080

2.phone 1280*728

3.pad 2948*1536

是不是完美適配了？烁臁Ｆ郊ā！
再來看下如果不用我們的適配布局的效果

好了 看下我們的layout
這是使用系統(tǒng)的ConstraintLayout

<?xml version="1.0" encoding="utf-8"?>

這是使用AdapterConstraintLayout

        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:srcCompat="@drawable/nav_music"/>

        android:layout_marginLeft="28dp"
        app:layout_constraintBottom_toTopOf="@+id/imageView7"
        android:layout_marginStart="28dp"
        app:layout_constraintTop_toBottomOf="@+id/imageView2"/>

        app:srcCompat="@drawable/music_piano"/>
</com.weihu.autolayout.AdapterConstraintLayout>

單位都是使用dp漠另，因為設(shè)計圖是1920*1080 所以px轉(zhuǎn)dp就使用px／3捏雌。
為什么使用dp不直接使用px呢？因為ConstraintLayout 在拖動控件時會把px轉(zhuǎn)為dp笆搓，要是我們用px設(shè)計好布局后一動就都轉(zhuǎn)為px是不是想死的心都有Ｐ允纬傲！所以干脆直接使用dp
好了
