三、部分代码
1：添加成绩信息
public class CreatScoreActivity extends BaseActivity {
// 标题
private TextView mTvTitle;
// 返回
private ImageView mIvBack;

private Button mSubmit;
private TextView bookTitle;
private EditText bookType;
private TextView courseWeek;

private List<User> mlistData = new ArrayList<User>();
private DialogListMsg dialogListMsg;
private ChoiceTypeAdapter listaAdapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_create_score);
initWidget();
initData();
}

@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.mIvBack:
finish();
break;
case R.id.courseWeek:
dialogListMsg.Show();
break;

case R.id.mSubmit:

Score message=new Score();
message.setScoreCourseId(course.getId());
message.setScoreCourseName(course.getCourseName());
message.setScoreStuId(mlistData.get(posIndex).getId());
message.setScoreStuName(mlistData.get(posIndex).getUserName());
message.setScoreInfor(bookType.getText().toString());
message.save();
CustomToast.showToast(this, "添加成功");
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
finish();
}
}, 1000);

break;

}
}

@Override
public void initWidget() {

bookTitle =(TextView) findViewById(R.id.bookTitle);
bookType = (EditText) findViewById(R.id.bookType);
courseWeek = (TextView) findViewById(R.id.courseWeek);
courseWeek.setOnClickListener(this);

mSubmit = (Button) findViewById(R.id.mSubmit);
mIvBack = (ImageView) findViewById(R.id.mIvBack);
mTvTitle = (TextView) findViewById(R.id.mTvTitle);
mTvTitle.setText("添加学生成绩信息");
mIvBack.setVisibility(View.VISIBLE);
mIvBack.setOnClickListener(this);
mSubmit.setOnClickListener(this);

}

private int posIndex;
Course course;
@Override
public void initData() {

course = (Course)this.getIntent().getSerializableExtra("msg");
bookTitle.setText(course.getCourseName());

dialogListMsg = new DialogListMsg(this);
dialogListMsg.setTitle().setText("请选择学生信息");
listaAdapter = new ChoiceTypeAdapter(this);

mlistData = User.listAll(User.class);
listaAdapter.setData(mlistData);
dialogListMsg.show_listview().setAdapter(listaAdapter);

dialogListMsg.show_listview().setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
posIndex = i;
courseWeek.setText(mlistData.get(posIndex).getUserName());
dialogListMsg.Close();
}
});

dialogListMsg.submit_no().setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
dialogListMsg.Close();
}
});
}

}

2：添加课程信息
public class CreatCourseActivity extends BaseActivity {
// 标题
private TextView mTvTitle;
// 返回
private ImageView mIvBack;

private Button mSubmit;
private EditText bookTitle;
private EditText bookType;
private TextView courseWeek;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_create_course);
initWidget();
initData();
}

@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.mIvBack:
finish();
break;
case R.id.courseWeek:
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm");// 设置日期格式
TimeSelector timeSelector = new TimeSelector(this, new TimeSelector.ResultHandler() {

@Override
public void handle(String time) {
courseWeek.setText(time);
}

}, df.format(new Date()), "2030-12-01 23:59");

timeSelector.setMode(TimeSelector.MODE.YMDHM);//显示年月日时分(默认)；
timeSelector.show();
break;

case R.id.mSubmit:

Course message=new Course();
message.setCourseName(bookTitle.getText().toString());
message.setCourseAddress(bookType.getText().toString());
message.setCourseWeek(courseWeek.getText().toString());
message.save();
CustomToast.showToast(this, "添加成功");
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
finish();
}
}, 1000);

break;

}
}

@Override
public void initWidget() {

bookTitle =(EditText) findViewById(R.id.bookTitle);
bookType = (EditText) findViewById(R.id.bookType);
courseWeek = (TextView) findViewById(R.id.courseWeek);
courseWeek.setOnClickListener(this);

mSubmit = (Button) findViewById(R.id.mSubmit);
mIvBack = (ImageView) findViewById(R.id.mIvBack);
mTvTitle = (TextView) findViewById(R.id.mTvTitle);
mTvTitle.setText("添加课程");
mIvBack.setVisibility(View.VISIBLE);
mIvBack.setOnClickListener(this);
mSubmit.setOnClickListener(this);

}

@Override
public void initData() {
bookTitle.setText("计算机基础");
bookType.setText("一号楼1001室");
}

}

3：查看课程信息

public class LookScoreActivity extends BaseActivity {

private int choiceType = 1;
// title
private TextView mTvTitle;
// 返回
private ImageView mIvBack;

private TextView paiming;
private TextView metName;
private TextView metPswd;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_lookscore);
initWidget();
initData();
}

@Override
public void initWidget() {

metName = (TextView) findViewById(R.id.metName);
paiming = (TextView) findViewById(R.id.paiming);
metPswd = (TextView) findViewById(R.id.metPswd);
mIvBack = (ImageView) findViewById(R.id.mIvBack);
mTvTitle = (TextView) findViewById(R.id.mTvTitle);
mTvTitle.setText("查看成绩信息");
mIvBack.setVisibility(View.VISIBLE);
mIvBack.setOnClickListener(this);

}

@Override
public void onClick(View v) {

switch (v.getId()) {
case R.id.mIvBack:
LookScoreActivity.this.finish();
break;

}
}

private List<Score> list_result = new ArrayList<Score>();
Course course;

@Override
public void initData() {

course = (Course)this.getIntent().getSerializableExtra("msg");
list_result = Score.findWithQuery(Score.class, "Select * from Score where scoreCourseId = " + course.getId()+" order by scoreInfor desc ");
for(int i=0;i<list_result.size();i++){
if((list_result.get(i).getScoreStuId()+"").equals(MemberUserUtils.getUid(this))){
paiming.setText("第"+(i+1)+"名");
metName.setText(list_result.get(i).getScoreCourseName());
metPswd.setText(list_result.get(i).getScoreInfor()+"分");
}
}

}

五、注意事项
如果遇到数据库未初始化的情况，解决办法如下：

1：Android Studio的Settings

2：在Android Studio在搜索框输入Instant Run（或者File——Settings——Build， Execution,Deployment——Instant Run
）

3：可以看到如下信息,第一排的Enable Instant Run to hot swap code/resource changes on deploy(default enabled)默认是有√的

4）现在将√去掉就OK了!
