How to assign wrap_content as height to dynamically loaded gridview

Question

I am loading gridview dynamically with buttons. So for that I am using scrollview, But if i assign wrap_content as height to gridview all the buttons are not displayed. I dont want to assign any static height for the gridview. This is the code which I am using: ``` ```

Accepted Answer

You need to create a new class for example

```
public class WrappingGridView extends GridView {

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

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

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

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    int heightSpec = heightMeasureSpec;
    if (getLayoutParams().height == LayoutParams.WRAP_CONTENT) {
        // The great Android "hackatlon", the love, the magic.
        // The two leftmost bits in the height measure spec have
        // a special meaning, hence we can't use them to describe height.
        heightSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
    }
    super.onMeasure(widthMeasureSpec, heightSpec);
}

}
```

also you need to change in your XML

```
<com.your.project.WrappingGridView
                android:id="@+id/gridviewtable"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:horizontalSpacing="10dp"
                android:numColumns="4"
                android:verticalSpacing="10dp"/>
```

and finally in your java class you need to chance the object GridView to WrappingGridView
