该篇说明
该篇我们进行单词测试实现讲解
也就是单词测试界面WordExamActivity中功能
布局也需要在xml中实现
但是也需要有单词测试视图类来设置一些值具体查看对照源码
在该界面中，测试完后会更新数据
效果如图
流程图
单词测试界面功能流程详解
1> 显示单词测试信息
a> 首先要加载单词测试数据
需要调用单词测试管理模块加载数据功能
private void loadWordExamData() { loadingExamDataProgressBar = (ProgressBar) findViewById(R.id.loadingExamDataProgressBar); loadingExamDataProgressBar.setVisibility(View.VISIBLE); new Thread() { public void run() { new WordExamManager().loadData(); SystemUtil.sleepvd(2000); myHandler.sendEmptyMessage(0); } }.start(); }
b> handler处理0的消息并初始及处理逻辑
@SuppressLint("HandlerLeak")
private void initHandler() {
myHandler = new Handler() {
public void handleMessage(android.os.Message msg) {
switch (msg.what) {
case 0:
wordExamLinearLayout.setVisibility(View.VISIBLE);
loadingExamDataProgressBar.setVisibility(View.GONE);
init();
logic();
break;
}
}
};
}
c> 接着在初始中加载显示单词测试界面
private void loadView() { //正确选项随机数 Global.rightOptionRandom = Math.floor(Math.random() * 4 + 1); WordDet wordDet = Global.wordDetList.get(Global.studyedWordId - 1); //单词测试标题 wordExamTitelTextView.setText(wordDet.wordStr + String.format(" /%s/", wordDet.pron)); WordExamView.initOptions(this); WordExamView.setOptionsData(wordDet); }
2> 四个选项添加监听
来实现点击判断选择的正确还是错误。进一步确定执行
监听类请自行查看源码
private void logic() { for(int i=1; i<=4; i++) { LinearLayout wordExamOptionll = WordExamView.weOptionLLayoutList.get(i-1); wordExamOptionll.setOnClickListener(new WordExamOptionClickListener(wordExamOptionll, i)); } }
3> 测试正确后下一个
a> 跳转下一个
单选正确后自动跳转到下一个
如果是已是最后一个，那么更新数据
public void examNext() { Global.studyedWordId += 1; if(Global.studyedWordId <= Global.wordList.size()) { timer.schedule(new TimerTask() { @Override public void run() { myHandler.sendEmptyMessage(1); } }, 1000); } else if((Global.studyedWordId > Global.wordList.size())) { updateData(); } }
b> 使用计时器控制1秒后跳转
Handler异步任务处理1的消息测试下个单词
@SuppressLint("HandlerLeak")
private void initHandler() {
myHandler = new Handler() {
public void handleMessage(android.os.Message msg) {
switch (msg.what) {
case 1:
if(timer != null) {
timer.cancel();
}
timer = new Timer();
showNextView();
break;
}
}
};
}
c> 更新数据
如果测试完最后一个，就进行更新数据。
如果从单词背诵界面跳转的，才更新记录次数
private void updateData() { clear(); if(parentStr != null && parentStr.equals("wordDet")) { updateDataProgressDialog.setMessage("正在更新数据"); updateDataProgressDialog.show(); new Thread(){ @Override public void run() { updateRecordTimes(); } }.start(); } else if(parentStr.equals("wordList")) { Toast.makeText(context, Global.selectUnitGroupFlagStr + "单元测组试完，回到单词列表界面！！！", Toast.LENGTH_LONG).show(); toNextView(WordListActivity.class); } }
d> 更新次数
> 没有完成次数进度才可设置需要更新数据
> 如果结果记录次数等于需要背诵的次数，则返回到今天任务
进度归0(会存储到数据库)，同时需要清空单词记录表及单词表
> 否则返回到单词列表，递增进度(不保存到数据库)
private void updateRecordTimes() {
int recitedtimes = Integer.parseInt(Global.studyPlanObj.lastReciteProgressStr.split("/")[0]); int resultRtimes = 0; if(recitedtimes != Global.defaultReciteTimes) { resultRtimes = recitedtimes + 1; Global.studyPlanObj.lastReciteProgressStr = resultRtimes + "/" + Global.defaultReciteTimes; if(resultRtimes == Global.defaultReciteTimes) { new ReciteManager().updateData(); SystemUtil.sleepvd(2000); myHandler.sendEmptyMessage(2); } else { new ReciteManager().updateReciteProgress(Global.studyPlanObj.lastReciteProgressStr); SystemUtil.sleepvd(2000); myHandler.sendEmptyMessage(3); } } }
4> 测试错误后的操作
测试错误后显示按钮操作
> 返回学习按钮，返回单词列表界面进行学习
> 继续测试按钮，重新开始测试
public void showButtonAfterNotRight() { returnToStudyButton.setVisibility(View.VISIBLE); continueExamButton.setVisibility(View.VISIBLE); returnToStudyButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { clear(); toNextView(WordListActivity.class); } }); continueExamButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Global.studyedWordId = 1; Global.examedWordId = 1; returnToStudyButton.setVisibility(View.GONE); continueExamButton.setVisibility(View.GONE); showNextView(); } }); }
单词测试后台功能详解
在加载数据以及更新次数方法使用到了后台模块
使用到了如下模块功能
> 单词测试管理WordExamManager的加载数据loadData()方法
> 背诵管理ReciteManager的更新背诵次数updateReciteProgress()方法
1> 单词测试管理加载数据详解
a> 首先是加载数据方法
public void loadData() { if(Global.examWordDetList == null) { if(wordDetManager == null) { wordDetManager = new WordDetManager(); } List<Word> tmexamWordList = getExamWordList(); Global.examWordDetList = wordDetManager.findMoreWordDet(tmexamWordList); } }
b> 获得测试单词范围
private List<Word> getExamWordList() { //确定单元及组 String unitGroupIntro = Global.todayStudyUnitGroupIntroList.get(Global.studyPlanObj.lastUnitGroupIndex); int cunit = Integer.parseInt(unitGroupIntro.split("-")[0]); int cgroup = Integer.parseInt(unitGroupIntro.split("-")[1]); int scopeBegin = -1; int scopeEnd = -1; //确定范围 if(cunit == 1 && cgroup <= 3) { scopeBegin = (cunit - 1) * ReciteConstant.DUNIT_WORD_COUNT + (cgroup+1) * ReciteConstant.DUNITG_WORD_COUNT; scopeEnd = scopeBegin + 3 * ReciteConstant.DUNITG_WORD_COUNT; } else { scopeEnd = (cunit - 1) * ReciteConstant.DUNIT_WORD_COUNT + cgroup * ReciteConstant.DUNITG_WORD_COUNT; if(scopeEnd > Global.studyPlanObj.allWordCount) { scopeEnd = Global.studyPlanObj.allWordCount - ReciteConstant.DUNITG_WORD_COUNT; } scopeBegin = scopeEnd - 3 * ReciteConstant.DUNITG_WORD_COUNT; } if(wordDao == null) { wordDao = new WordDao(); } String pathStr = PathConstant.STUPLAN_PATH + "sp_" + Global.studyPlanObj.name; return wordDao.findScope(scopeBegin, scopeEnd, pathStr); }
c> 根据单词列表得到单词详解列表
这里引用单词详解模块WordDetManager的查找更多单词详解方法
请查看源码点到该类
public List<WordDet> findMoreWordDet(List<Word> wordList) { List<WordDet> wordDetList = new ArrayList<WordDet>(); for(Word word : wordList) { WordDet wordDet = findDetWord(word.wordStr); if(wordDet != null) { wordDetList.add(wordDet); } }
return wordDetList; }
查找某个单词的单词详解方法
public WordDet findDetWord(String wordStr) { if(dictDao == null) { dictDao = new DictDao(); } String wordDefinition = dictDao.findWordDefinition(wordStr); WordDet wordDet = jsonDefiToDefWord(wordStr, wordDefinition); return wordDet; }
2> 背诵管理更新次数详解
更新背诵次数，直接调用相应的dao即可
public void updateReciteProgress(String reciteProgressStr) { if(reciteDao == null) { reciteDao = new ReciteDao (); } String pathStr = PathConstant.STUPLAN_PATH + "sp_" + Global.studyPlanObj.name; reciteDao.updateReciteProgress(reciteProgressStr, Global.studyPlanObj.name, pathStr); }
