完整代码在最下面。。
头布局xml：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="50dp">
<LinearLayout

</LinearLayout>添加头布局并隐藏
private void initView(Context context) {
header = LayoutInflater.from(context).inflate(R.layout.refresh_header, null);
measureView(header);
headerHeight = header.getMeasuredHeight();
topPadding(-headerHeight);
addHeaderView(header);
setOnScrollListener(this);
}设置上边距
/**
* 设置header上边距
*
* @param topPadding 上边距
*/
private void topPadding(int topPadding) {
header.setPadding(header.getPaddingLeft(), topPadding,
header.getPaddingRight(), header.getPaddingBottom());
header.invalidate();
}隐藏头布局得告诉父布局头布局占多大宽高
/**
* 通知父布局占多大宽高
*/
private void measureView(View view) {
ViewGroup.LayoutParams layoutParams = view.getLayoutParams();
if (layoutParams == null) {
layoutParams = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
}
int width = ViewGroup.getChildMeasureSpec(0, 0, layoutParams.width);
int height;
int tempHeight = layoutParams.height;
if (tempHeight > 0) {
// 高度不是0的时候，要填充
height = MeasureSpec.makeMeasureSpec(tempHeight, MeasureSpec.EXACTLY);
} else {
// 高度是0的时候不要填充
height = MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED);
}
view.measure(width, height);
}给布局添加滚动事件
/**
* 滚动事件
*
* @param view 当前可见的view
* @param firstVisibleItem 当前界面第一个可见的item的位置
* @param visibleItemCount
* @param totalItemCount
*/
@Override
public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount,
int totalItemCount) {
this.firstVisibleItem = firstVisibleItem;
}
@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
this.scrollState = scrollState;
}
按下时的三个事件
/**
* 触摸事件
*/
@Override
public boolean onTouchEvent(MotionEvent ev) {
switch (ev.getAction()) {
case MotionEvent.ACTION_DOWN:
// 判断界面是不是在最顶端
if (firstVisibleItem == 0) {
isRemark = true;
startY = (int) ev.getY();
}
break;
case MotionEvent.ACTION_MOVE:
onMove(ev);
break;
case MotionEvent.ACTION_UP:
if (state == RELESE) {
state = REFRESHING;
//加载最新数据
refreshViewByState();
mListener.onRefresh();
} else if (state == PULL) {
state = NONE;
isRemark = false;
refreshViewByState();
}
break;
}
return super.onTouchEvent(ev);
}
手指移动的操作
/**
* 判断移动过程中的操作
*/
private void onMove(MotionEvent ev) {
if (!isRemark) {
return;
}
//当前已经移动到什么位置
int tempY = (int) ev.getY();
//手指移动的距离
int space = tempY - startY;
int topPadding = space - headerHeight;
switch (state) {
case NONE:
if (space > 0) {
state = PULL;
refreshViewByState();
}
break;
case PULL:
topPadding(topPadding);
if (space > headerHeight + 30 && scrollState == SCROLL_STATE_TOUCH_SCROLL) {
state = RELESE;
refreshViewByState();
}
break;
case RELESE:
topPadding(topPadding);
if (space < headerHeight + 30) {
state = PULL;
refreshViewByState();
} else if (space <= 0) {
state = NONE;
isRemark = false;
refreshViewByState();
}
break;
case REFRESHING:
break;
}
}手指移动改变文本，这里用了两个不同的动画用于旋转下拉箭头
/**
* 根据当前状态改变界面显示
*/
private void refreshViewByState() {
TextView textView = header.findViewById(R.id.txt_xia_la);
ImageView imageView = header.findViewById(R.id.jian_tou);
ProgressBar progressBar = header.findViewById(R.id.progress);
// RotateAnimation animation1 = new RotateAnimation(0, 180,
// RotateAnimation.RELATIVE_TO_SELF, 0.5f,

// //设置时间间隔500ms
// animation1.setDuration(500);
// //当它完成时将会持续动画执行 转换
// animation1.setFillAfter(true);
// RotateAnimation animation2 = new RotateAnimation(180, 0,
// RotateAnimation.RELATIVE_TO_SELF, 0.5f,
// RotateAnimation.RELATIVE_TO_SELF, 0.5f);
// animation2.setDuration(500);
// animation2.setFillAfter(true);
switch (state) {
case NONE:
topPadding(-headerHeight);
imageView.clearAnimation();
break;
case PULL:
imageView.setVisibility(VISIBLE);
progressBar.setVisibility(GONE);
textView.setText("下拉可以刷新");
imageView.clearAnimation();
break;
case RELESE:
imageView.setVisibility(VISIBLE);
progressBar.setVisibility(GONE);
textView.setText("松开可以刷新");
imageView.clearAnimation();
// imageView.setAnimation(animation1);
ObjectAnimator.ofFloat(imageView, "rotation",
0, 180F).setDuration(500).start();
break;
case REFRESHING:
topPadding(headerHeight);
imageView.setVisibility(GONE);
progressBar.setVisibility(VISIBLE);
textView.setText("正在刷新");
imageView.clearAnimation();
break;
}
}
获取完数据
/**
* 获取完数据
*/
public void refreshComplete() {
state = NONE;
isRemark = false;
refreshViewByState();
TextView textView = header.findViewById(R.id.txt_last_time);
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
Date date = new Date(System.currentTimeMillis());
String time = format.format(date);
textView.setText(time);
}
设置接口给activity用于刷新后的操作
/**
* 刷新数据接口
*/
public interface RefreshListener {
void onRefresh();
}
public void setInterface(RefreshListener listener) {
this.mListener = listener;
}MainActivity.class
public class PullToRefreshActivity extends AppCompatActivity implements PullToRefresh.RefreshListener {
private PullToRefresh pullToRefreshView;
// private PullLoadRefresh pullLoadRefresh;
private ListView listView;
private ArrayAdapter<String> adapter;
String items[] = {"A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M",
"N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z"};
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pull_to_refresh);
pullToRefreshView = (PullToRefresh) findViewById(R.id.refresh_view);
// listView = (ListView) findViewById(R.id.refresh_list);
adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, items);
pullToRefreshView.setAdapter(adapter);
pullToRefreshView.setInterface(this);
}
@Override
public void onRefresh() {
//获取最新数据
//显示数据
//刷新数据
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
if (!pullToRefreshView.isBottom) {
pullToRefreshView.refreshComplete();
} else {
pullToRefreshView.refreshComplete2();
}
ToastUtil.showToast(PullToRefreshActivity.this, "sss");
}
}, 2000);
}
}activity_pull_to_refresh.xml<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

</LinearLayout>至此下拉刷新结束。
上拉加载和下拉刷新原理都是一样的。
