该篇说明
该篇我们来详解创建计划功能实现。
创建计划功能是在创建计划界面中的。
也就是在CreatePlanActivity中
在后台模块中只描述管理层，其它的数据库操作等请自行查看
效果如图
执行流程图
创建计划UI界面功能说明
1> 横幅显示创建计划字符
hfTitleTextView = (TextView) findViewById(R.id.hfTitleTextView);
hfTitleTextView.setText("创建计划");
2> 创建计划项的填写
a步骤> 单词书名输入操作，只需要显示组件和获取组件即可
private void init() {
studyNameEditText = (EditText) findViewById(R.id.studyNameEditText);
}
b步骤1> 初始化选择单词书相关属性及值
private void init() { selectWordBookRelativeLayout =
(RelativeLayout) findViewById(R.id.selectWordBookRelativeLayout);
wordBooknameTextView = (TextView) findViewById(R.id.wordBooknameTextView);
wordBookname = WordBookConstant.WDBK_CATE_ARRAY[0];
wordBooknameTextView.setText(wordBookname);}
b步骤2> 选择单词书布局点击监听
private void logic() {
selectWordBookRelativeLayout.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
alertSelectWorkBook();
}
});
}
b步骤3> 弹出的单选框选择单词书
private void alertSelectWorkBook () {
new AlertDialog.Builder(context)
.setTitle("请选择书籍")
.setIcon(android.R.drawable.ic_dialog_info)
.setSingleChoiceItems(WordBookConstant.WDBK_CATE_ARRAY, wordBookSelectedIndex,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
wordBookname = WordBookConstant.WDBK_CATE_ARRAY[which];
wordBookSelectedIndex = which;
wordBooknameTextView.setText(wordBookname);
Toast.makeText(context, "单词书是:" + wordBookname, Toast.LENGTH_LONG).show();
}
}
)
.setNegativeButton("取消", null)
.show();
}
c步骤1> 初始选择每天单元量布局组件及值
private void init() {
selectDayUnitRelativeLayout =
(RelativeLayout) findViewById(R.id.selectDayUnitRelativeLayout);
dayUnitTextView = (TextView) findViewById(R.id.dayUnitTextView);
dayUnitStr = ReciteConstant.DUNITCT_ITEMS_ARRAY[0];
dayUnitTextView.setText(dayUnitStr);
}
c步骤2> 选择每天单词量布局点击监听
private void logic() {
selectDayUnitRelativeLayout.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
alertSelectDayUnit();
}
});
}
c步骤3> 弹出的单选框选择每天单元量
private void alertSelectDayUnit() {
new AlertDialog.Builder(context)
.setTitle("请选择每天单元量")
.setIcon(android.R.drawable.ic_dialog_info)
.setSingleChoiceItems(ReciteConstant.DUNITCT_ITEMS_ARRAY, dayUnitSelectedIndex,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
dayUnitStr = ReciteConstant.DUNITCT_ITEMS_ARRAY[which];
dayUnitSelectedIndex = which;
dayUnitTextView.setText(dayUnitStr);
Toast.makeText(context, "每天单元量:" + dayUnitStr, Toast.LENGTH_LONG).show();
}
}
)
.setNegativeButton("取消", null)
.show();
}
3> 创建学习计划确定按钮监听
private void logic() {
confirmButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
if(validate()) {
createStudyPlan();
}
}
});
}
4> 效验信息
在创建前需要进效验信息，也就是输入和选择项的信息的
这些信息将作为计划的一些属性
private boolean validate() {
studyPlaname = studyNameEditText.getText().toString().trim();
if(studyPlaname == null || "".equals(studyPlaname)) {
Toast.makeText(context, "学习名必须填写", Toast.LENGTH_LONG).show();
return false;
}
return true;
}
5> 创建学习计划方法
因为是耗时操作，所以也需要在多线程完成
private void createStudyPlan() {
createStudyPlanProgressDialog.setMessage("正在创建计划数据");
createStudyPlanProgressDialog.show();
Thread createStudyPlanThread =
new Thread(new CreateStudyPlanThread());
createStudyPlanThread.start();
}
6> 创建学习计划线程
除了创建计划以外，还需要初始单词表数据，也就是将sdcard对应的单词书数据复制到了学习计划中
class CreateStudyPlanThread implements Runnable {
public void run() {
//创建计划
new StudyPlanManager().create(
studyPlaname, wordBookname, Integer.parseInt(dayUnitStr));
//初始单词表数据
new WordManager().initData(studyPlaname, wordBookname);
SystemUtil.sleepvd(2000);
myHandler.sendEmptyMessage(0);
}
}
创建计划功能后台模块讲解
创建计划功能调用了两个管理模块
一个是计划管理模块StudyPlanManager
一个单词管理模块WordManager
1> 计划管理的模块创建功能
也就是创建计划功能
public void create(String studyPlaname, String wordBookname, int dayUnit) {
if(studyPlanDao == null) {
studyPlanDao = new StudyPlanDao();
}
//---------
// 创建学习计划对象
StudyPlan studyPlan = new StudyPlan();
studyPlan.name = studyPlaname;
studyPlan.wordBookname = wordBookname;
studyPlan.allWordCount = WordBookConstant.getWordCountFromWordBook(wordBookname);
studyPlan.dayUnitCount = dayUnit;
//总单元量(除不尽+1，最后一个单元少于70)
studyPlan.allUnitCount =
studyPlan.allWordCount % ReciteConstant.DUNITG_WORD_COUNT == 0 ?
studyPlan.allWordCount / ReciteConstant.DUNITG_WORD_COUNT :
studyPlan.allWordCount / ReciteConstant.DUNITG_WORD_COUNT + 1;
//所有新单元耗时天数，不算复习(除不尽+1, 最后一天少于70个单词)
studyPlan.needDayCount =
studyPlan.allWordCount % (dayUnit * ReciteConstant.DUNITG_WORD_COUNT) == 0 ?
studyPlan.allWordCount / (dayUnit * ReciteConstant.DUNITG_WORD_COUNT) :
studyPlan.allWordCount / (dayUnit * ReciteConstant.DUNITG_WORD_COUNT) + 1;
studyPlan.createDated = DateUtil.getDateString(DateUtil.FORMATE_DAY);
//一些计划中背诵的属性
studyPlan.lastTodayTaskState = ReciteConstant.TODAYTASK_STUDY;
Global.defaultReciteTimes = Integer.parseInt(ReciteConstant.RECTIMES_ITEMS_ARRAY[0]);
studyPlan.lastReciteProgressStr = 0 + "/" + Global.defaultReciteTimes;
studyPlan.lastUnitGroupIndex = 0;
//---------
//---------
//添加数据
String spPathStr = PathConstant.STUPLAN_PATH + "sp_" + studyPlaname;
// 创建学习计划文件
createStudyPlanFile(spPathStr);
//添加数据到学习计划数据库中
studyPlanDao.add(studyPlan, spPathStr);
//---------
}
2> 单词管理的的初始单词表数据
就是将sdcard对应的单词书数据复制到了学习计划中
调用了单词书的数据库操作以及单词的数据库操作，这里数据库操作都是本地的sqlite3
public void initData(String studyPlaname, String wordBookname) {
if(wordDao == null) {
wordDao = new WordDao();
}
if(wordBookDao == null) {
wordBookDao = new WordBookDao();
}
List<String> wordStrList = wordBookDao.findWordBook(wordBookname);
String pathStr = PathConstant.STUPLAN_PATH + "sp_" + studyPlaname;
wordDao.initAddMoreUseTransaction(wordStrList, pathStr);}
