ImageView в адаптере просмотра списка корректно изменяет размер, только если я прокручиваю вниз и снова прокручиваю вверх?

Question

В моем адаптере списка просмотра я устанавливаю параметры макета для изображения, "play_button_final"

Когда он впервые загружается, он выглядит так:

Хотя после прокрутки вниз и прокрутки вверх это выглядит так:

Он меняется на первый каждый раз, когда я уведомляю своих наблюдателей... как я могу предотвратить это?

Это мой код адаптера. Обратите внимание на getView(). Я устанавливаю эти изображения в "STREAM_LAYOUT"

@Override
public View getView(final int position, View convertView, ViewGroup parent) {

    holder = null;
    int type = getItemViewType(position);

    if (convertView == null) {
        convertView = mInflater.inflate(R.layout.listview_cell, null);
        holder = new ViewHolder();
    } else {
        holder = (ViewHolder) convertView.getTag();
    }



     switch (type) {

Мой XML, если вы хотите увидеть это:

   <RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:adjustViewBounds="true"

        android:scaleType="fitXY"
        android:src="@drawable/boombox"
        android:id="@+id/boombox"
        />

    <ImageView
        android:id="@+id/play_stop_button"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_toRightOf="@id/boombox"
        android:layout_alignParentRight="true"
        />




</RelativeLayout>

Answer 1

Попробуйте это: измените высоту родительского макета на wrap_content

<RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">

Или вы можете попробовать использовать LinearLayout

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:adjustViewBounds="true"

        android:scaleType="fitXY"
        android:src="@drawable/boombox"
        android:id="@+id/boombox"
        />

    <ImageView
        android:id="@+id/play_stop_button"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_toRightOf="@id/boombox"
        android:layout_alignParentRight="true"
        />
</LinearLayout >

Или используйте пропорции:

<LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="horizontal">

        <ImageView
            android:layout_width="0dp"
            android:weight="4"
            android:layout_height="wrap_content"
            android:adjustViewBounds="true"
            android:scaleType="fitXY"
            android:src="@drawable/boombox"
            android:id="@+id/boombox"
            />

        <ImageView
            android:id="@+id/play_stop_button"
            android:layout_width="0dp"
            android:weight="1"
            android:layout_height="fill_parent"
            android:layout_toRightOf="@id/boombox"
            android:layout_alignParentRight="true"
            />
    </LinearLayout >
