**已解决** Uri图片未显示在ScrollView

Question

嗨，我正在显示使用URI和Picasso库存储在手机中的图像，当我在没有ScrollView的新Activity中执行此操作时，但在包含两个带有线性布局的卡片视图的原始活动布局中执行相同操作时，该图像正确显示并且不显示ScrollView图像，但显示带有应用程序原色的空白图像。

这是我的TryActivity代码，一切正常：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".ui.TryActivity">

<androidx.cardview.widget.CardView
    android:layout_width="match_parent"
    android:layout_height="370dp"
    android:layout_marginStart="8dp"
    android:layout_marginTop="16dp"
    android:layout_marginEnd="8dp"
    android:padding="10dp"
    app:cardCornerRadius="10dp"
    app:cardElevation="5dp">

    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingBottom="12dp"
        android:paddingTop="8dp">

        <TextView
            android:id="@+id/time_const"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginStart="8dp"
            android:layout_marginTop="8dp"
            android:layout_marginEnd="8dp"
            android:text="@string/time_const"
            android:textColor="@android:color/black"
            android:textAppearance="?android:textAppearanceMedium"
            android:textStyle="italic"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintHorizontal_bias="0.24"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent" />

        <TextView
            android:id="@+id/pic_time"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginStart="12dp"
            android:textAppearance="?android:textAppearanceMedium"
            android:textColor="@android:color/darker_gray"
            android:textStyle="bold"
            app:layout_constraintBaseline_toBaselineOf="@+id/time_const"
            app:layout_constraintStart_toEndOf="@+id/time_const" />

        <ImageView
            android:id="@+id/camera_pic"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginStart="16dp"
            android:layout_marginEnd="16dp"
            android:tint="@color/colorPrimary"
            android:contentDescription="@string/app_name"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:srcCompat="@drawable/camera" />

        <ImageView
            android:id="@+id/click_click"
            android:layout_width="match_parent"
            android:layout_height="250dp"
            android:maxHeight="250dp"
            android:layout_marginStart="8dp"
            android:layout_marginTop="16dp"
            android:layout_marginEnd="8dp"
            android:layout_marginBottom="16dp"
            android:contentDescription="@string/app_name"
            app:layout_constraintBottom_toTopOf="@+id/camera_pic"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/time_const"/>

    </androidx.constraintlayout.widget.ConstraintLayout>

</androidx.cardview.widget.CardView>

</FrameLayout> 

这是我用于此活动的Java代码：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_try);

    ImageView imageView = findViewById(R.id.click_click);

    Picasso.get()
            .load("file:/storage/emulated/0/Pictures/JPEG_20190330_190925_8486610829519670776.jpg")
            .into(imageView);
}

但是，如果我尝试在原始活动中执行相同的操作，则将无效：

这是我的xml布局：

我在这里犯了一个愚蠢的错误，我在应用程序图标图像中设置了单击图像，这就是它被应用程序原色拉伸的原因。从我那一天起花了几个小时！
