Question

アプリケーションの起動をクリックし、ボタンの上にクラッシュが、ボタン上のImageButton

背後CustomListViewでクラッシュこのコード形式のリストビューカスタムアダプタ、それをクリックします

holder.submitAttendance.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      String Lt,teacherName,status = null,startTime,endTime; 
      if(holder.radioButtonPresent.isChecked()) 
      { 
       status=holder.radioButtonPresent.getText().toString(); 
      } 
      else if(holder.radioButtonAbsent.isChecked()) 
      { 
       status=holder.radioButtonAbsent.getText().toString(); 
      } 
      startTime=holder.etxtStart_time_Picker.getText().toString(); 
      endTime=holder.etxtEnd_time_Picker.getText().toString(); 
      Lt=holder.txtlt.getText().toString(); 
      teacherName=holder.txtteacher.getText().toString(); 
     dataBaseHelper1.insertData(Lt,teacherName,status,startTime,endTime); 
     } 
    }); 

このフォームのSQLiteデータベースヘルパークラス

public class DataBaseHelper extends SQLiteOpenHelper 
{ 

public static String DATABASE_NAME = "Teacher.db"; 
public static String TABLE_NAME = "Teacher_Table"; 
public static String Col_1_LT = "LT"; 
public static String Col_2_TName = "Teacher_Name"; 
public static String Col_3_Status = "Status"; 
public static String Col_4_StartTime = "StartTime"; 
public static String Col_5_EndTime = "EndTime"; 

public DataBaseHelper(Context context) { 
    super(context, DATABASE_NAME, null, 1); 
} 
@Override 
public void onCreate(SQLiteDatabase db) { 
    String query="create table" + TABLE_NAME +"(LT TEXT PRIMARY 
    KEY,Teacher_Name TEXT, Status TEXT, StartTime TEXT, EndTime TEXT)"; 
    db.execSQL(query); 
} 
@Override 
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) 
{ 
    db.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME); 
    onCreate(db); 
} 
    ContentValues contentValues = new ContentValues(); 
    public boolean insertData(String Lt, String TeacherName, String Status,String StartTime, String EndTime) 
    { 
    SQLiteDatabase db = this.getWritableDatabase(); 
    contentValues.put(Col_1_LT, Lt); 
    contentValues.put(Col_2_TName, TeacherName); 
    contentValues.put(Col_3_Status, Status); 
    contentValues.put(Col_4_StartTime, StartTime); 
    contentValues.put(Col_5_EndTime, EndTime); 
    long result = db.insert(TABLE_NAME, null, contentValues); 
    db.close(); 
    //to check whether Data is Inserted in Database 
    if (result == -1) { 
     { 
      return false; 
     } 
    } else 
     { 
     return true; 
     } 
}}

Answer 1

あなたのCreate Tableクエリ内のスペースやカンマ不足している：へ

変更を：

クラッシュlogcatである

String query = "create table " + TABLE_NAME +"(LT TEXT PRIMARY 
KEY,Teacher_Name TEXT, Status TEXT, StartTime TEXT, EndTime TEXT);"; 
db.execSQL(query);
