ListFragment images change size
I have a ListFragment
with a custom ListAdapter
that lazy loads images and displays a view with the image on the left and some text on the right. The custom list item I'm using looks like this:
<?xml ve开发者_Python百科rsion="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ImageView
android:id="@+id/image"
android:maxWidth="80dp"
android:adjustViewBounds="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:padding="10dp"
android:textSize="16sp"
android:gravity="left|center_vertical" />
</LinearLayout>
This is all working fine, but when I click a list item and then click back, most times the list displays with the images at their full size, not at 80dp width as specified. If I wait a while before pressing back, the list sometimes loads correctly.
Does anyone know how I could fix this? I want the images to always display at 80dp width. Thanks.
This is how I use images with different widths and heights. Force every image to 85x85, cropped.
<ImageView
android:src="@drawable/some_img"
android:layout_width="85dip"
android:layout_height="85dip"
android:scaleType="centerCrop"
/>
You might consider using either centerCrop or centerInside.
I wouldn't be surprised if android:adjustViewBounds="true"
is causing the issue you are seeing.
Another possible culprit is that you are setting android:layout_height="fill_parent"
in the TextView
which should be wrap_content
