仿sina微博的listview更多分页按钮

<?xml version="1.0" encoding="UTF-8"?>

<LinearLayout android:layout_width="fill_parent" android:orientation="vertical"

android:layout_height="wrap_content" android:focusable="true"

xmlns:android="http://schemas.android.com/apk/res/android"

android:background="@drawable/loadmore" android:layout_centerVertical="true"

android:layout_centerHorizontal="true">

<!--

<Button android:id="@+id/loadMoreButton"

android:layout_width="fill_parent"

android:layout_height="wrap_content" android:text="更多" />

-->

<LinearLayout android:gravity="center" android:layout_height="wrap_content"

android:orientation="vertical" android:layout_width="fill_parent">

<ImageView android:background="@drawable/divider"

android:layout_height="2.0dip" android:layout_width="fill_parent" />

</LinearLayout>

<LinearLayout android:gravity="center" android:layout_gravity="center"

android:orientation="horizontal" android:layout_centerVertical="true"

android:layout_width="fill_parent" android:layout_height="60dip">

<TextView android:textSize="20.0sp" android:textColor="#ff545454"

android:gravity="center" android:id="@id/tv_msg" android:text="更多"

android:layout_width="fill_parent" android:layout_height="wrap_content"/>

<LinearLayout android:gravity="center" android:layout_height="wrap_content"

android:layout_gravity="center" android:orientation="horizontal"

android:id="@+id/llloading" android:layout_width="fill_parent">

<ProgressBar android:layout_gravity="center_vertical"

android:id="@id/footprogress" android:layout_width="wrap_content"

android:layout_height="wrap_content" android:indeterminateBehavior="repeat"

style="?android:progressBarStyleSmallInverse" />

<TextView android:textColor="#ff000000" android:gravity="left|center"

android:padding="2.0px" android:layout_width="wrap_content"

android:layout_height="wrap_content" android:text="读取中" />

</LinearLayout>

</LinearLayout>

</LinearLayout>
期中上面的一个@drawable/loadmore是一个选择器如下

<?xml version="1.0" encoding="utf-8"?>

<selector

xmlns:android="http://schemas.android.com/apk/res/android"

>

<item

android:state_pressed="false"

android:drawable="@drawable/listview_gradient"

>

</item>

<item

android:state_pressed="true"

android:drawable="@drawable/list_selector_background_pressed"

>

</item>

</selector>其中list_selector_background_pressed系统带的一个按钮在listview源代码中可以找到或sdk中也有

2、同时加载footer布局

list_footer = (LinearLayout)LayoutInflater.from(FansActivity.this).inflate(R.layout.sinalist_footer, null);

tv_msg = (TextView)list_footer.findViewById(R.id.tv_msg);

loading = (LinearLayout)list_footer.findViewById(R.id.llloading);

//btloadmore = (Button)list_footer.findViewById(R.id.loadMoreButton);

listView = getListView();

top_panel = (View)findViewById(R.id.fans_top);

top_btn_left = (Button)top_panel.findViewById(R.id.top_btn_left);

top_btn_right = (Button)top_panel.findViewById(R.id.top_btn_right);

top_title = (TextView)top_panel.findViewById(R.id.top_title);

listView.addFooterView(list_footer, null, false);//利用FooterVIew分页动态加载,参数false是不让选择
3、list_footer中增加按钮事件如下

list_footer.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

try {

// Toast.makeText(FansActivity.this, "我将消失了",

// Toast.LENGTH_SHORT).show();

//list_footer.setBackgroundColor(Color.YELLOW);

//list_footer.invalidate();

new FansThread().start();

//tv_msg.setEnabled(false);

tv_msg.setVisibility(View.GONE);// 隐藏更多提示的TextView

loading.setVisibility(View.VISIBLE);// 显示最下方的进度条

} catch (Exception e) {

e.printStackTrace();

}

}

});
