应用程序意外停止。强制关闭。单击“更新”按钮后，此消息仅针对一个意图，对于另一个意图，该应用程序可以正常工作。该应用程序将获取两个字符串输入并将它们更新到数据库并查看表。我的应用程序正在完美更新，但是当我单击查看它时出现错误消息。

public void onCreate(SQLiteDatabase db) {
    // TODO Auto-generated method stub
    db.execSQL("CREATE TABLE " + DATABASE_NAME + "(" +
            KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
            KEY_NAME + " TEXT NOT NULL, " + 
            KEY_HOTNESS + " TEXT NOT NULL);"

    );


}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    // TODO Auto-generated method stub
    db.execSQL("DROP TABLE IF EXISTS " + DATABASE_NAME);
    onCreate(db);
}

}

public hotornot(Context c){
ourcontext = c;
}
public hotornot open(){
ourHelper = new DbHelper(ourcontext);
ourDatabase = ourHelper.getWritableDatabase();
return this;
}
public void close(){
ourHelper.close();
}
public Long createentry(String name, String hotness){
ContentValues cv= new ContentValues();
cv.put(KEY_NAME, name);
cv.put(KEY_HOTNESS,hotness );
return ourDatabase.insert(DATABASE_TABLE, null, cv);
}
    public String getdata() {
// TODO Auto-generated method stub
String[] columns = new String[]  {KEY_ROWID, KEY_NAME, KEY_HOTNESS};
Cursor c = ourDatabase.query(DATABASE_TABLE, columns, null, null, null, null,      null);
String result = "";
int irow = c.getColumnIndex(KEY_ROWID);
int iname = c.getColumnIndex(KEY_NAME);
int ihotness = c.getColumnIndex(KEY_HOTNESS);
for(c.moveToFirst(); !c.isAfterLast(); c.moveToNext())
{
    result = result + c.getString(irow) + " " + c.getString(iname) + " " + c.getString(ihotness) + "\n";

}
return result;
}
}

这是更新的清单文件：

Your exception stack shows that the error is due to the table (peopletable) not being present.

A quick glance at your code shows the following:

db.execSQL("CREATE TABLE " + DATABASE_NAME + "(" + KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + KEY_NAME + " TEXT NOT NULL, " + KEY_HOTNESS + " TEXT NOT NULL);"

The error is probably due to a typo in your code. You are using DATABASE_NAME instead of DATABASE_TABLE in your code, as a result of which your table name is different from the one that the rest of your code is expecting.
