I am developing an android app page.

This page will load images from url. But the loaded images not obey layout constraint. The result appear some unexpected blank space. Why, and how to solve this?

Here is my code:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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:id="@+id/main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".for_dynamic_add_img_and_desc">

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <LinearLayout
            android:id="@+id/LinearLayout_content"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

        </LinearLayout>
    </ScrollView>

</androidx.constraintlayout.widget.ConstraintLayout>

package com.example.emptyactivityjava;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;
import androidx.activity.EdgeToEdge;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.graphics.Insets;
import androidx.core.view.ViewCompat;
import androidx.core.view.WindowInsetsCompat;
import com.squareup.picasso.Picasso;

public class for_dynamic_add_img_and_desc extends AppCompatActivity {

    LinearLayout LinearLayout_content;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        EdgeToEdge.enable(this);
        setContentView(R.layout.activity_for_dynamic_add_img_and_desc);
        ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.main), (v, insets) -> {
            Insets systemBars = insets.getInsets(WindowInsetsCompat.Type.systemBars());
            v.setPadding(systemBars.left, systemBars.top, systemBars.right, systemBars.bottom);
            return insets;
        });

        LinearLayout_content = findViewById(R.id.LinearLayout_content);

        String[] imgs_url = {
                "https://amateurphotographer.com/wp-content/uploads/sites/7/2023/04/Paulina-Stopka-vertical-landscapes-Tryfan-Eryri-National-Park-Tatra-Mountains.jpg",
                "https://images.pexels.com/photos/247599/pexels-photo-247599.jpeg?auto=compress&cs=tinysrgb&w=1260&h=750&dpr=1",
                "https://samuelearp.com/wp-content/uploads/2023/10/IMG_1512-1536x1273.jpeg",
        };

        String[] descs = {
                "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa",
                "bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb",
                "cccccccccccccccccccccccccccccccccccccccccccccccc"
        };

        for (int i = 0; i < 3; i++) {
            View view = LayoutInflater.from(for_dynamic_add_img_and_desc.this).inflate(R.layout.item_template, null);
            Picasso.get().load(imgs_url[i]).into((ImageView) view.findViewById(R.id.img));
            ((TextView) (view.findViewById(R.id.desc))).setText(descs[i]);
            LinearLayout_content.addView(view);
        }
    }
}

item_template.xml:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/img"
        android:layout_width="300dp"
        android:layout_height="wrap_content" />

    <TextView
        android:id="@+id/desc"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_constraintTop_toBottomOf="@id/img" />

</androidx.constraintlayout.widget.ConstraintLayout>

And the result is, it appear some unexpected blank space(how to solve this):
