Android: GridView width not wrapping to content?

I am trying to display a GridView in a Dialog. Despite all my efforts, the GridView width grows to the entire screen, instead of wrapping to the columns. The layout and an image depicting the issue are below (I set a background color for the GridView to illustrate the issue).

<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/colorgridview"
    android:background="#FF00CCBB"
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"
    android:numColumns="4"
    android:verticalSpacing="5dp"
    android:horizontalSpacing="5dp"
    android:columnWidth="70dp"
    android:stretchMode="none"
/>

enter image description here

Had the same problem... I solved it with overridden onMeasure()

public class GridViewEx extends GridView {

    private int mRequestedNumColumns = 0;

    public GridViewEx(Context context) {
        super(context);
    }

    public GridViewEx(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public GridViewEx(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public void setNumColumns(int numColumns) {
        super.setNumColumns(numColumns);

        if (numColumns != mRequestedNumColumns) {
            mRequestedNumColumns = numColumns;
        }
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        if (mRequestedNumColumns > 0) {
            int width = (mRequestedNumColumns * getColumnWidth())
                    + ((mRequestedNumColumns-1) * getHorizontalSpacing())
                    + getListPaddingLeft() + getListPaddingRight();

            setMeasuredDimension(width, getMeasuredHeight());    
        }
    }
}

I know that this post is a bit outdated. But if someone needs a solution to this, this answer may come in handy.

It is possible to set the view's width after screen measurement.

To do this:

Let your class implement the OnGlobalLayoutListener. The screen is measured when the onGlobalLayout method is called. We can do our magic here. GridView.getLayoutParams().width = ....

edit: I wasn't very clear on how to add the onGlobalLayoutListener. See plugmind's post, he shows how to add it. Can't figure out how to get view/layout width/height

Kind regards, Bram

It's certainly possible to set a fixed layout_width (in dp). Since the number of your columns is also fixed, could this be a workaround for you?

I think you should use android:layout_width="fill_parent" instead of android:layout_width="wrap_content" because wrap content use the minimum place it needs. On the other hand, fill_parent use all space needed. More over you should get rid of "android:columnWidth="70dp".
