gridView height is too tall when using an imageView inside

问题

I'm having an issue with the height for the cells inside the GridView. Each of my cells will have an imageView inside like so:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:orientation="vertical"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent">

<GridView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:verticalSpacing="10dp"
        android:horizontalSpacing="10dp"
        android:id="@+id/eventGridView" android:numColumns="2"/>
</LinearLayout>

Here is the ImageView for each cell

<com.example.scheduling_android.view.RoundedCornerImageView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:maxWidth="150dp"
        android:maxHeight="150dp"
        xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/eventImageView"
        android:adjustViewBounds="false"/>

I was playing around with different image size for my imageView. What I got was that whenever my image becomes larger (say, 400 x 400px) the height of the cell becomes very tall (around double the size of the width, note that I set the grid to use 2 columns). However, when I save my image as a smaller size (say, 160 x 160px), the gridView came out correctly. The height and the width matches.

Here's a screenshot:

What seems to be the problem? Could it be that the large image is causing gridView to calculate the height of its cell incorrectly? What can I do to fix this?

回答1:

I think you haven't set adjustViewBounds to true. Can you set as follows?

imageView.setAdjustViewBounds(true);

回答2:

Here i have user 3 column for in each row and it works fine. Gallery view set the column width at run time,

mPhotoGalleryGridView.setColumnWidth(display.getWidth() / 3);

in layout

<GridView android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/photogallerygridview"      
    android:padding="5dp"
    android:verticalSpacing="5dp"
    android:horizontalSpacing="5dp"
    android:stretchMode="columnWidth"
    android:numColumns="3"
    android:gravity="center">    
</GridView>

in adapter: set imageview height and width,

imageview.setMaxHeight(150);
        imageview.setMinimumHeight(150);

Hope useful to you.

Try the below code. The width should be in dips

 android:adjustViewBounds="true"
 android:maxWidth="150dip"
 android:maxHeight="150dip"

回答4:

Use wrap_content instead of using fill_parent.

Because fill_parent will actually take original height of image and try to fill it in the screen. Even if u use 400x400 image and set layout_width = "160dp" and layout_height = "160dp" , it will work because we are not allowing image to display more than that.
