Question

listview可以添加两个头部布局吗

Answer 1

第一个头布局我 设置了一下 位置，目的是为了证明，在自定义下拉刷新时，当listview已经添加了一个headerview时候，可以继续添加一个headerview，不影响下拉刷新

代码如下:

MainActivity

package com.ss.hsx;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;

public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
MyListView listView = (MyListView) findViewById(R.id.listView);

String[] data = new String[] { "第一个", "第二个", "第三个" };

ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, data);

listView.setAdapter(adapter);
}
}

MyListView

package com.ss.hsx;

import android.content.Context;
import android.util.AttributeSet;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ListView;

public class MyListView extends ListView {
View one;

public MyListView(Context context) {
super(context);
initHeaderView(context);
}

public MyListView(Context context, AttributeSet attrs) {
super(context, attrs);
initHeaderView(context);

}

public MyListView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
initHeaderView(context);

}

private void initHeaderView(Context context) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
one = inflater.inflate(R.layout.one, null);
View two = inflater.inflate(R.layout.two, null);

addHeaderView(one);
addHeaderView(two);

}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
//控制第一个头部布局的位置
one.setPadding(0, -1 * one.getHeight()/2, 0, 0);

}
}
