下拉刷新框架Android-Ultra-Pull-To-Refresh的使用

GitHub地址：https://github.com/liaohuqiu/android-Ultra-Pull-To-Refresh

首先看下项目结构：

在ptr-demo中的build.gradle中

compile 'in.srain.cube:clog:1.0.2'
compile 'in.srain.cube:cube-sdk:1.0.44.38'

在整个项目中app的build.gradle中

compile(project(':ptr-lib'))

在布局文件中使用PtrClassicFrameLayout

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
 xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff">

<in.srain.cube.views.ptr.PtrClassicFrameLayout
 xmlns:cube_ptr="http://schemas.android.com/apk/res-auto"
android:id="@+id/fragment_rotate_header_with_text_view_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#fff"
cube_ptr:ptr_duration_to_close="200"
cube_ptr:ptr_duration_to_close_header="1000"
cube_ptr:ptr_keep_header_when_refresh="true"
cube_ptr:ptr_pull_to_fresh="false"
cube_ptr:ptr_ratio_of_header_height_to_refresh="1.2"
cube_ptr:ptr_resistance="1.7">
<!-- 放入任何view-->
</in.srain.cube.views.ptr.PtrClassicFrameLayout>

</RelativeLayout>

在自定义PtrClassicFrameLayout中可以放入任何view

SecondActivity.java

package com.zhoujian.application;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import in.srain.cube.views.ptr.PtrClassicFrameLayout;
import in.srain.cube.views.ptr.PtrDefaultHandler;
import in.srain.cube.views.ptr.PtrFrameLayout;

/**
 * Created by zhoujian on 2017/1/9.
 */

public class SecondActivity extends Activity 
{

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);

final PtrClassicFrameLayout ptrFrame = (PtrClassicFrameLayout) findViewById(R.id.fragment_rotate_header_with_text_view_frame);

        ptrFrame.setLastUpdateTimeRelateObject(this);
        ptrFrame.setPtrHandler(new PtrDefaultHandler() {
@Override
public void onRefreshBegin(PtrFrameLayout frame) {
                frame.postDelayed(new Runnable() {
@Override
public void run() {
                        ptrFrame.refreshComplete();
                    }
                }, 1500);
            }

@Override
public boolean checkCanDoRefresh(PtrFrameLayout frame, View content, View header) {
return true;
            }
        });
    }
}

activity_second.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
 xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

cube_ptr:ptr_duration_to_close="200"
cube_ptr:ptr_duration_to_close_header="1000"
cube_ptr:ptr_keep_header_when_refresh="true"
cube_ptr:ptr_pull_to_fresh="false"
cube_ptr:ptr_ratio_of_header_height_to_refresh="1.2"
cube_ptr:ptr_resistance="1.7">

android:gravity="center"
android:text="我是TextView"
android:textColor="#000000"
android:textSize="30sp"/>

</in.srain.cube.views.ptr.PtrClassicFrameLayout>

</RelativeLayout>
