Кривая волны в студии android

Question

Привет друзья, может кто-нибудь, пожалуйста, помогите мне в этом. Я хочу создать страницу входа в систему таким образом

Но это не работает в эмуляторе и android 8 телефона. это работает в android 5 телефон. Работает нормально, если я удаляю изображение, которое содержит кривую. получаю эту ошибку при попытке в android 8 или эмуляторе.

Answer 1

Здесь проблема в вашем изображении в первых двух тегах пути android:pathData="" пусто. Из-за пустого приложения pathData происходит сбой, и вы получаете ошибку.

Пожалуйста, используйте другое изображение или ниже векторный код:

<?xml version="1.0" encoding="utf-8"?>
<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="600dp"
    android:height="600dp"
    android:viewportWidth="600"
    android:viewportHeight="600">
    <path
        android:fillColor="#11b6ed"
        android:strokeWidth="1"
        android:pathData="M0 00L637.5 00L637.5 519.0C528.33 483.94 424.58 482.69 326.25 516.02C227.91 549.35 119.17 545.6 0 504.77L0 00Z" />
    <path

    <path

        android:pathData="M0 00L637.5 00L637.5 519.0C528.33 483.94 424.58 482.69 326.25 516.02C227.91 549.35 119.17 545.6 0 504.77L0 00Z" />
</vector>

И используйте android:src="@drawable/wave" вместо app:srcCompat="@drawable/wave"

Я надеюсь, что это работает для вас.

Answer 2

Если srcCompat, вы должны использовать android.support.v7.widget.AppCompatImageView вместо ImageView.

 <android.support.v7.widget.AppCompatImageView
    android:id="@+id/image"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="364dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintHorizontal_bias="0.0"
    app:layout_constraintStart_toStartOf="parent"
    app:srcCompat="@drawable/wave" />

И добавить это в build.gradle

 android {
   defaultConfig {
      vectorDrawables {
         useSupportLibrary = true
      }
    }
   }

ИЛИ используйте src вместо srcCompat в ImageView.

Надеюсь, это поможет.
