效果演示
随手做的一个小玩意，还有很多功能没有完善，倘有疏漏，万望海涵。
实现功能总览
实现了登录、注册、忘记密码、成绩查询、考勤情况、课表查看、提交作业、课程打卡等。
代码
登录与忘记密码界面
登录与忘记密码界面采用的是tablayout+viewpager+pageradapter实现的
一、添加布局文件
view view_homepager = layoutinflater.from( student.this ).inflate( r.layout.homeppage_item,null,false ); view view_data = layoutinflater.from( student.this ).inflate( r.layout.data_item,null,false ); view view_course = layoutinflater.from( student.this ).inflate( r.layout.course_item,null,false ); view view_my = layoutinflater.from( student.this ).inflate( r.layout.my_item,null,false );
private list<view> views = new arraylist<>( );
views.add( view_homepager ); views.add( view_data ); views.add( view_course ); views.add( view_my );
二、添加标题文字
private list<string> titles = new arraylist<>( );
titles.add( "首页" ); titles.add( "数据" ); titles.add( "课程" ); titles.add( "我的" );
三、绑定适配器
/*pageradapter 适配器代码如下*/
public class viewpageradapter extends pageradapter {
private list<view> views;
private list<string> titles;
public viewpageradapter(list<view> views,list<string> titles){
this.views = views;
this.titles = titles;
}
@override
public int getcount() {
return views.size();
}
@override
public boolean isviewfromobject(@nonnull view view, @nonnull object object) {
return view == object;
}
@nonnull
@override
public object instantiateitem(@nonnull viewgroup container, int position) {
container.addview( views.get( position ) );
return views.get( position );
}
@override
public void destroyitem(@nonnull viewgroup container, int position, @nonnull object object) {
container.removeview( views.get( position ) );
}
@nullable
@override
public charsequence getpagetitle(int position) {
return titles.get( position );
}
}
viewpageradapter adapter = new viewpageradapter( views,titles );
for (string title : titles){
title.addtab( title.newtab().settext( title ) );
}
title.setupwithviewpager( viewpager );
viewpager.setadapter( adapter );
注册界面
一、创建两个drawable文件
其一
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
<solid android:color="#63b8ff"/>
<size android:width="20dp" android:height="20dp"/>
</shape>
其二
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
<solid android:color="#ffffff"/>
<size android:height="20dp" android:width="20dp"/>
<stroke android:width="1dp" android:color="#eaeaea"/>
</shape>
二、将其添加数组内
private final int[] identity = {r.drawable.press_oval_textview,r.drawable.notpress_oval_textview};
三、动态变化背景
private void selectstudent(){
midentity_student.setbackgroundresource( identity[0] );
midentity_teacher.setbackgroundresource( identity[1] );
}
private void selectteacher(){
midentity_student.setbackgroundresource( identity[1] );
midentity_teacher.setbackgroundresource( identity[0] );
}
考勤界面
主要是通过绘制一个圆，圆环、内圆、文字分别使用不同的背景颜色，并将修改背景颜色的接口暴露出来。
一、circleprogressbar代码如下
public class circleprogressbar extends view {
// 画实心圆的画笔
private paint mcirclepaint;
// 画圆环的画笔
private paint mringpaint;
// 画圆环的画笔背景色
private paint mringpaintbg;
// 画字体的画笔
private paint mtextpaint;
// 圆形颜色
private int mcirclecolor;
// 圆环颜色
private int mringcolor;
// 圆环背景颜色
private int mringbgcolor;
// 半径
private float mradius;
// 圆环半径
private float mringradius;
// 圆环宽度
private float mstrokewidth;
// 圆心x坐标
private int mxcenter;
// 圆心y坐标
private int mycenter;
// 字的长度
private float mtxtwidth;
// 字的高度
private float mtxtheight;
// 总进度
private int mtotalprogress = 100;
// 当前进度
private double mprogress;
public circleprogressbar(context context) {
super( context );
}
public circleprogressbar(context context, @nullable attributeset attrs) {
super( context, attrs );
initattrs(context,attrs);
initvariable();
}
public circleprogressbar(context context, @nullable attributeset attrs, int defstyleattr) {
super( context, attrs, defstyleattr );
}
private void initattrs(context context, attributeset attrs) {
typedarray typearray = context.gettheme().obtainstyledattributes(attrs,
r.styleable.taskscompletedview, 0, 0);
mradius = typearray.getdimension(r.styleable.taskscompletedview_radius, 80);
mstrokewidth = typearray.getdimension(r.styleable.taskscompletedview_strokewidth, 10);
mcirclecolor = typearray.getcolor(r.styleable.taskscompletedview_circlecolor, 0xffffffff);
mringcolor = typearray.getcolor(r.styleable.taskscompletedview_ringcolor, 0xffffffff);
mringbgcolor = typearray.getcolor(r.styleable.taskscompletedview_ringbgcolor, 0xffffffff);
mringradius = mradius + mstrokewidth / 2;
}
private void initvariable() {
//内圆
mcirclepaint = new paint();
mcirclepaint.setantialias(true);
mcirclepaint.setcolor(mcirclecolor);
mcirclepaint.setstyle(paint.style.fill);
//外圆弧背景
mringpaintbg = new paint();
mringpaintbg.setantialias(true);
mringpaintbg.setcolor(mringbgcolor);
mringpaintbg.setstyle(paint.style.stroke);
mringpaintbg.setstrokewidth(mstrokewidth);
//外圆弧
mringpaint = new paint();
mringpaint.setantialias(true);
mringpaint.setcolor(mringcolor);
mringpaint.setstyle(paint.style.stroke);
mringpaint.setstrokewidth(mstrokewidth);
//mringpaint.setstrokecap(paint.cap.round);//设置线冒样式，有圆 有方
//中间字
mtextpaint = new paint();
mtextpaint.setantialias(true);
mtextpaint.setstyle(paint.style.fill);
mtextpaint.setcolor(mringcolor);
mtextpaint.settextsize(mradius / 2);
paint.fontmetrics fm = mtextpaint.getfontmetrics();
mtxtheight = (int) math.ceil(fm.descent - fm.ascent);
}
@override
protected void ondraw(canvas canvas) {
super.ondraw( canvas );
mxcenter = getwidth() / 2;
mycenter = getheight() / 2;
//内圆
canvas.drawcircle( mxcenter, mycenter, mradius, mcirclepaint );
//外圆弧背景
rectf oval1 = new rectf();
oval1.left = (mxcenter - mringradius);
oval1.top = (mycenter - mringradius);
oval1.right = mringradius * 2 + (mxcenter - mringradius);
oval1.bottom = mringradius * 2 + (mycenter - mringradius);
canvas.drawarc( oval1, 0, 360, false, mringpaintbg ); //圆弧所在的椭圆对象、圆弧的起始角度、圆弧的角度、是否显示半径连线
//外圆弧
if (mprogress > 0) {
rectf oval = new rectf();
oval.left = (mxcenter - mringradius);
oval.top = (mycenter - mringradius);
oval.right = mringradius * 2 + (mxcenter - mringradius);
oval.bottom = mringradius * 2 + (mycenter - mringradius);
canvas.drawarc( oval, -90, ((float) mprogress / mtotalprogress) * 360, false, mringpaint ); //
//字体
string txt = mprogress + "%";
mtxtwidth = mtextpaint.measuretext( txt, 0, txt.length() );
canvas.drawtext( txt, mxcenter - mtxtwidth / 2, mycenter + mtxtheight / 4, mtextpaint );
}
}
//设置进度
public void setprogress(double progress) {
mprogress = progress;
postinvalidate();//重绘
}
public void setcirclecolor(int color){
mringpaint.setcolor( color );
postinvalidate();//重绘
}
}
签到界面
签到界面就倒计时和位置签到
一、倒计时
采用的是thread+handler
在子线程内总共发生两种标志至handler内，0x00表示倒计时未完成，0x01表示倒计时完成。
private void countdown(){
new thread( ){
@override
public void run() {
super.run();
for (int j = 14; j >= 0 ; j--) {
for (int i = 59; i >= 0; i--) {
message message = handler.obtainmessage();
message.what = 0x00;
message.arg1 = i;
message.arg2 = j;
handler.sendmessage( message );
try {
thread.sleep( 1000 );
} catch (interruptedexception e) {
e.printstacktrace();
}
}
}
message message = handler.obtainmessage( );
message.what = 0x01;
handler.sendmessage( message );
}
}.start();
}
final handler handler = new handler( ){
@override
public void handlemessage(@nonnull message msg) {
super.handlemessage( msg );
switch (msg.what){
case 0x00:
if (msg.arg2 >= 10){
signinminutes.settext( msg.arg2+":" );
}else if (msg.arg2 < 10 && msg.arg2 > 0){
signinminutes.settext( "0"+msg.arg2+":" );
}else {
signinminutes.settext( "00"+":" );
}
if (msg.arg1 >= 10){
signinseconds.settext( msg.arg1+"" );
}else if (msg.arg1 < 10 && msg.arg1 > 0){
signinseconds.settext( "0"+msg.arg1 );
}else {
signinseconds.settext( "00" );
}
break;
case 0x01:
signinseconds.settext( "00" );
signinminutes.settext( "00:" );
break;
}
}
};
二、位置签到
位置签到采用的是百度地图sdk
public class locationcheckin extends appcompatactivity {
private mapview baidumapview;
private textview currentposition,mlatitude,mlongitude,currentdate,signinposition;
private button submitmessage,successsignin;
private imageview locationsignin_exit;
private view view = null;
private popupwindow mpopupwindow;
private locationclient client;
private baidumap mbaidumap;
private double latitude = 0;
private double longitude = 0;
private boolean isfirstlocate = true;
@override
protected void oncreate(bundle savedinstancestate) {
super.oncreate( savedinstancestate );
if (build.version.sdk_int >= 21) {
view decorview = getwindow().getdecorview();
decorview.setsystemuivisibility( view.system_ui_flag_layout_fullscreen | view.system_ui_flag_layout_stable );
getwindow().setstatusbarcolor( color.transparent );
}
sdkinitializer.initialize( getapplicationcontext() );
client = new locationclient( getapplicationcontext() );//获取全局context
client.registerlocationlistener( new mybaidumap() );//注册一个定位监听器，获取位置信息，回调此定位监听器
setcontentview( r.layout.activity_location_check_in );
initview();
initbaidumap();
initpermission();
initpopwindows();
listener();
}
private void initview(){
baidumapview = findviewbyid( r.id.baidu_mapview );
currentposition = findviewbyid( r.id.currentposition );
submitmessage = findviewbyid( r.id.submitmessage );
mlatitude = findviewbyid( r.id.latitude );
mlongitude = findviewbyid( r.id.longitude );
locationsignin_exit = findviewbyid( r.id.locationsignin_exit );
}
private void initpopwindows(){
view = layoutinflater.from( locationcheckin.this ).inflate( r.layout.signin_success ,null,false);
currentdate = view.findviewbyid( r.id.currentdate );
signinposition = view.findviewbyid( r.id.signinposition );
successsignin = view.findviewbyid( r.id.success);
mpopupwindow = new popupwindow( view, viewgroup.layoutparams.match_parent,viewgroup.layoutparams.wrap_content );
mpopupwindow.setfocusable( true ); //获取焦点
mpopupwindow.setbackgrounddrawable( new bitmapdrawable() );
mpopupwindow.setoutsidetouchable( true ); //点击外面地方，取消
mpopupwindow.settouchable( true ); //允许点击
mpopupwindow.setanimationstyle( r.style.mypopupwindow ); //设置动画
calendar calendar = calendar.getinstance();
int hour = calendar.get( calendar.hour_of_day );
int minute = calendar.get( calendar.minute );
string shour,sminute;
if (hour < 10){
shour = "0"+hour;
}else {
shour = ""+hour;
}
if (minute < 10){
sminute = "0"+minute;
}else {
sminute = ""+minute;
}
currentdate.settext( shour+":"+sminute );
//signinposition.settext( position+"000");
successsignin.setonclicklistener( new view.onclicklistener() {
@override
public void onclick(view v) {
mpopupwindow.dismiss();
}
} );
}
private void showpopwindows(){
mpopupwindow.showatlocation( view, gravity.center,0,0 );
}
private void initbaidumap(){
/*百度地图初始化*/
mbaidumap = baidumapview.getmap();//获取实例，可以对地图进行一系列操作，比如：缩放范围，移动地图
mbaidumap.setmylocationenabled(true);//允许当前设备显示在地图上
}
private void navigateto(bdlocation location){
if (isfirstlocate){

mbaidumap.animatemapstatus(update);
isfirstlocate = false;
}
mylocationdata.builder builder = new mylocationdata.builder();

string[] permissions = permissionlist.toarray( new string[permissionlist.size()] );//转化为数组
activitycompat.requestpermissions( locationcheckin.this, permissions, 1 );//一次性申请权限

成绩查询界面
采用的是md的cardstackview，需要实现一个adapter适配器，此适配器与recyclerview适配器构建类似
一、创建stackadapter 适配器
package com.franzliszt.student.queryscore;
public class stackadapter extends com.loopeer.cardstack.stackadapter<integer> {
public stackadapter(context context) {
super(context);
}
@override

h.onbind(data, position);
}
if (holder instanceof coloritemwithnoheaderviewholder) {
coloritemwithnoheaderviewholder h = (coloritemwithnoheaderviewholder) holder;
h.onbind(data, position);
}
if (holder instanceof coloritemviewholder) {
coloritemviewholder h = (coloritemviewholder) holder;
h.onbind(data, position);
}
}
@override
protected cardstackview.viewholder oncreateview(viewgroup parent, int viewtype) {
view view;
switch (viewtype) {

view = getlayoutinflater().inflate(r.layout.other_item, parent, false);
return new coloritemviewholder(view);
case r.layout.other_item_thank:

return new coloritemviewholder(view);
case r.layout.other_item_note_1:
view = getlayoutinflater().inflate(r.layout.other_item_note_1, parent, false);
return new coloritemviewholder(view);
case r.layout.other_item_note_2:
view = getlayoutinflater().inflate(r.layout.other_item_note_2, parent, false);
return new coloritemviewholder(view);
default:
view = getlayoutinflater().inflate(r.layout.first_semester, parent, false);
return new coloritemviewholder(view);
}
}
@override

@override
public void onclick(view v) {
((cardstackview)itemview.getparent()).performitemclick(coloritemlargeheaderviewholder.this);
}
});
}
}
}
二、绑定适配器
queryscorecardstackview.setitemexpendlistener( this );
adapter = new stackadapter( this );
queryscorecardstackview.setadapter( adapter );
三、为每一个子项添加背景色
public static integer[] color_datas = new integer[]{
r.color.color_1,
r.color.color_2,
r.color.color_3,
r.color.color_4,
r.color.color_5,
r.color.color_6,
r.color.color_7,
r.color.color_8,
r.color.color_9,
r.color.color_10,
};
new handler( ).postdelayed( new runnable() {
@override
public void run() {
adapter.updatedata( arrays.aslist( color_datas ) );
}
} ,200);
