Why am I getting a different Sized list row while using a CustomListAdapter even though i tried giving a specific value to the custom list row

问题

这是listview_row.xml的代码：

  1. <?xml version="1.0" encoding="utf-8"?>
  2. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  3.     xmlns:app="http://schemas.android.com/apk/res-auto"
  4.     xmlns:tools="http://schemas.android.com/tools"
  5.     android:id="@+id/ll"
  6.     android:layout_width="match_parent"
  7.     android:layout_height="wrap_content">
  9.     <ImageView
  10.         android:id="@+id/imageViewID"
  11.         android:layout_width="112dp"
  12.         android:layout_height="match_parent"
  13.         android:layout_weight="1"
  14.         app:srcCompat="@android:drawable/ic_menu_today" />
  16.     <LinearLayout
  17.         android:layout_width="match_parent"
  18.         android:layout_height="match_parent"
  19.         android:layout_weight="1"
  20.         android:gravity="center_vertical"
  21.         android:orientation="vertical">
  23.         <TextView
  24.             android:id="@+id/nameTextViewID"
  25.             android:layout_width="match_parent"
  26.             android:layout_height="wrap_content"
  27.             android:text="TextView"
  28.             android:textAlignment="center"
  29.             android:textSize="18sp" />
  31.         <TextView
  32.             android:id="@+id/infoTextViewID"
  33.             android:layout_width="match_parent"
  34.             android:layout_height="wrap_content"
  35.             android:text="TextView"
  36.             android:textAlignment="center"
  37.             android:textSize="18sp" />
  38.     </LinearLayout>
  39. </LinearLayout>

但在完成其他代码后，输出是这样的：
我只能看到一页一行，第二行远在下面

我已经向下滚动了一点并展示了

有谁能帮我解决这个问题，以便像正常的ListView一样显示行，而不是每页显示一行？

我对此不太了解，提前谢谢。

英文:

I have created a custom listView but when I run the code I get 1 row per screen. I have put the layout width and height of the parent layout in the listview_row.xml as match_parent and wrap_Content respectively.

this is the code for the listview_row.xml

  1. <?xml version="1.0" encoding="utf-8"?>
  2. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  3.     xmlns:app="http://schemas.android.com/apk/res-auto"
  4.     xmlns:tools="http://schemas.android.com/tools"
  5.     android:id="@+id/ll"
  6.     android:layout_width="match_parent"
  7.     android:layout_height="wrap_content">
  9.     <ImageView
  10.         android:id="@+id/imageViewID"
  11.         android:layout_width="112dp"
  12.         android:layout_height="match_parent"
  13.         android:layout_weight="1"
  14.         app:srcCompat="@android:drawable/ic_menu_today" />
  16.     <LinearLayout
  17.         android:layout_width="match_parent"
  18.         android:layout_height="match_parent"
  19.         android:layout_weight="1"
  20.         android:gravity="center_vertical"
  21.         android:orientation="vertical">
  23.         <TextView
  24.             android:id="@+id/nameTextViewID"
  25.             android:layout_width="match_parent"
  26.             android:layout_height="wrap_content"
  27.             android:text="TextView"
  28.             android:textAlignment="center"
  29.             android:textSize="18sp" />
  31.         <TextView
  32.             android:id="@+id/infoTextViewID"
  33.             android:layout_width="match_parent"
  34.             android:layout_height="wrap_content"
  35.             android:text="TextView"
  36.             android:textAlignment="center"
  37.             android:textSize="18sp" />
  38.     </LinearLayout>
  39. </LinearLayout>

but after all rest coding, I get the output as
i can see only one row a screen the 2nd row is far below

here I have scrolled a bit down and showed

Can anyone help me with this such that to display rows like a normal listView instead of getting 1 row per page?

I am new to this and thanks in advance.
