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;

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();

}
private void InitView(){

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) {

}
} );
}
private void ShowPopWindows(){

}
private void InitBaiDuMap(){
/*百度地图初始化*/

}
private void navigateTo(BDLocation location){
if (isFirstLocate){

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> {

@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);
