在开发中用到了需要ScrollView嵌套GridView的情况,由于这两款控件都自带滚动条,当他们碰到一起的时候便会出问题,即GridView会显示不全。

解决办法,自定义一个GridView控件

 

package com.weijie.app_user.activity.order;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.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);
}
}

 

XML布局代码:



XML布局代码
<ScrollView Android:layout_height="wrap_content"
android:layout_width="fill_parent" android:id="@+id/scroll_content">
<com.yourclass.MyGridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/grid_view" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:numColumns="auto_fit"
android:horizontalSpacing="1dip" android:verticalSpacing="1dip"
android:columnWidth="150dip" android:stretchMode="columnWidth"
android:gravity="center">

</com.yourclass.MyGridView>
</ScrollView>



 

Java调用代码:

MyGridView gridview = (MyGridView) findViewById(R.id.grid_view);
gridview.setAdapter(new ImageAdapter(this));
