ฉันทดสอบใน Android 8 (อุปกรณ์ 360dp x 640dp) และทุกอย่างก็โอเค แต่ใน Android 5.1.1 (อุปกรณ์ 320dp x 480dp) มันผิดรูปหน้าจอที่เต็มไปด้วย VectorDrawable ของฉันและปล่อยอัตราส่วนกว้างยาวฉันจะแก้ไขได้อย่างไร

และชุดรูปแบบ

@ManiKandan ทำไมต้อง 24dp ?? SVG ของฉันไม่ใช่ไอคอนมันเป็นภาพประกอบขนาดใหญ่
WebMaster

@ManiKandan ฉันอัพเดทโพสต์และเพิ่มเวกเตอร์แบบเต็ม
WebMaster

ฉันโพสต์ก่อนหน้านี้ XML ตัวแรกคือเลย์เอาท์สาดของฉันและ XML ตัวที่สองคือเวกเตอร์อันดับสามคือธีม

VectorDrawableกำหนดวัตถุ drawable คงที่ คล้ายกับรูปแบบ SVG แต่ละกราฟิกแบบเวกเตอร์ถูกกำหนดเป็นลำดับชั้นของต้นไม้ซึ่งประกอบด้วยวัตถุพา ธ และกลุ่ม แต่ละพา ธ ประกอบด้วยเรขาคณิตของโครงร่างของวัตถุและกลุ่มที่มีรายละเอียดสำหรับการแปลงรูป

คุณสามารถใช้SDP - หน่วยที่ปรับขนาดได้

android SDK ที่มีหน่วยขนาดใหม่ - sdp (scalable dp) หน่วยขนาดนี้ปรับขนาดด้วยขนาดหน้าจอ มันสามารถช่วยนักพัฒนา Android รองรับหน้าจอหลายหน้าจอ

วิธีเพิ่ม sdp ในโครงการของคุณ (ใช้ Android Studio และ Gradle) build.gradle

dependencies {
  implementation 'com.intuit.sdp:sdp-android:1.0.6'
}

ตอนนี้เพิ่มSDP แทน DP

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="@dimen/_300sdp"
    android:height="@dimen/_225sdp"
    android:viewportWidth="512"
    android:viewportHeight="512">

หมายเหตุ - ใช้AppCompatImageView (ด้วยapp:srcCompat) แทนImageViewในเค้าโครงของคุณ

 <android.support.v7.widget.AppCompatImageView //Or androidx.appcompat.widget.AppCompatImageView
    app:srcCompat="@drawable/your_svg"
    />

แต่ imageview ช่วยได้จริงเมื่อใช้หน้าจอสแปลชที่ "ถูกต้อง"? อย่างไรก็ตามถ้ามันรักษาอัตราส่วนกว้างยาวของ API ทั้งหมดฉันคิดว่ามันใช้งานได้

ปัญหาเกี่ยวข้องกับ API ของ 21, 22 และ 23 สำหรับสิ่งที่คุณต้องใช้ในการวาดบิตแมป สิ่งที่คุณต้องทำคือสร้าง 2 เลเยอร์ของ drawable list-list แล้วใส่ลงไปใน drawable-v22 และ drawable-v24 หากว่าโฟลเดอร์เหล่านี้ไม่มีอยู่แล้วเพียงแค่สร้างมันใน res / และสังเกตว่าคุณต้องตั้งโปรเจค ดู Poject เพื่อดู (ดูภาพด้านล่าง)

สำหรับ v24 คุณใช้อันที่คุณมีอยู่แล้ว:

<?xml version="1.0" encoding="utf-8"?><layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
    android:drawable="@android:color/white"
    android:gravity="fill" />

<item

    android:gravity="center"
    android:src="@drawable/splash_screen" >
</item>

</layer-list>

สำหรับ drawable-v21 คุณใช้สิ่งต่อไปนี้ (โปรดทราบว่าด้วยเหตุผลบางประการ drawable เหล่านี้จะไม่ทำงานบน API ที่สูงกว่า 23)

<?xml version="1.0" encoding="utf-8"?><layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
    android:drawable="@android:color/white"
    android:gravity="fill" />

<item android:gravity="center">
    <bitmap
        android:gravity="center"
        android:src="@drawable/splash_screen" />
</item>
