Question

我正在使用ExpandableHeightGridView，但我无法计算gridview的正确高度，我使用外部布局制作的自定义行，但它在底部剪切了几行，这是代码：

public class ExpandableHeightGridView extends GridView {

boolean expanded = false;

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

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

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

public boolean isExpanded() {
    return expanded;
}

@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    if (isExpanded()) {
        int expandSpec = MeasureSpec.makeMeasureSpec(MEASURED_SIZE_MASK,
                MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);

        ViewGroup.LayoutParams params = getLayoutParams();
        params.height = getMeasuredHeight();
    } else {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }
}

public void setExpanded(boolean expanded) {
    this.expanded = expanded;
}
}

自定义行

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@null"
android:orientation="vertical" >

<TextView
    android:id="@+id/textViewBioAnno"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="5dp"
    android:gravity="center_horizontal"
    android:text="TextView"
    android:textColor="@color/oro"
    android:textSize="20sp" />

<TextView
    android:id="@+id/textViewBioTesto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center_horizontal"
    android:text="TextView"
    android:textSize="15sp" />

</LinearLayout>

我的活动：

...
g = (ExpandableHeightGridView) findViewById(R.id.mebersListGridView);
arrayAdapter = new StandardArrayAdapter(this,
            R.layout.activity_bio, arrayList);
g.setExpanded(true);
g.setAdapter(arrayAdapter);
...

GridView可扩展高度
