ListView的addHeaderView(),ScrollView嵌套ListView和GridView只显示一行。

addHeaderView()

一、使用addHeaderView(View view)方法给ListView添加Header，添加之后Header占据了ListView的第一项，因此item的点击事件的position需要-1。

ScrollView嵌套

二、重写ListView

public class MyListView extends ListView {

public MyListView(Context context) {
// TODO Auto-generated method stub
super(context);
}

public MyListView(Context context, AttributeSet attrs) {
// TODO Auto-generated method stub
super(context, attrs);
}

public MyListView(Context context, AttributeSet attrs, int defStyle) {
// TODO Auto-generated method stub
super(context, attrs, defStyle);
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
// TODO Auto-generated method stub
int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);
}
}

三、重写GridView

public class MyGridView extends GridView{
public MyGridView(Context context, AttributeSet attrs) {
super(context, attrs);
}

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

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

@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);
}
}
