我有一个不适用于我的应用程序的现有 Sqlite 数据库。谁能知道如何帮助我？此外，我只用一张表制作了一个小测试 .db 文件，它工作正常。认为我发布图片的大数据库有问题，但我不确定是什么。
我已经发布了数据库外观的图片，如果您需要更多屏幕截图等，请询问。

这是 onCreate：
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView contentLog = (TextView) findViewById(R.id.content_log);
// Create the database
DataBaseHelper myDbHelper = new DataBaseHelper(
this.getApplicationContext());
myDbHelper = new DataBaseHelper(this);
try {
myDbHelper.createDataBase();
contentLog.append("Database Created\n");
} catch (IOException ioe) {
throw new Error("Unable to create database");
}
// Open the database
try {
myDbHelper.openDataBase();
contentLog.append("Database Opened\n");
} catch (SQLException sqle) {
sqle.printStackTrace();
}
// Get the readable version
SQLiteDatabase db = myDbHelper.getReadableDatabase();
contentLog.append("Get the readable database\n");
// Make a select
Cursor cur = db.rawQuery(
"SELECT libelle FROM detail_verbe ORDER BY libelle ASC;", null);
cur.moveToPosition(0);
Log.v(TAG, "Nb Col:" + cur.getColumnCount());
Log.v(TAG, "Nb Records:" + cur.getCount());
cur.close();
contentLog.append("Select:\t" + cur.getColumnCount() + " cols, "
+ cur.getCount() + " rows\n");
// Make an insert
ContentValues values = new ContentValues();
values.put("libelle", "Serval");
values.put("single_present", "Cat");
long servalCatID = db.insert("detail_verbe", null, values);
Log.v(TAG, "Serval Cat Inserted @: " + servalCatID);
contentLog.append("Insert @ \t" + servalCatID + "\n");
// Check insert
cur = db.rawQuery(
"SELECT libelle FROM detail_verbe ORDER BY libelle ASC;", null);
cur.moveToPosition(0);
Log.v(TAG, "Nb Col:" + cur.getColumnCount());
Log.v(TAG, "Nb Records:" + cur.getCount());
cur.close();
contentLog.append("Select:\t" + cur.getColumnCount() + " cols, "
+ cur.getCount() + " rows\n");
// dumb
cur = db.rawQuery(
"SELECT libelle FROM detail_verbe ORDER BY libelle ASC;",
null);
contentLog.append("\nDUMP\n");
int i = 0;
cur.moveToFirst();
while (cur.isAfterLast() == false) {
contentLog.append("(" + i++ + ")\t\t" + cur.getString(0) + "\t"
+ cur.getString(1) + "\n");
cur.moveToNext();
}
cur.moveToPosition(0);
// Close
myDbHelper.close();
contentLog.append("Database closed.");
// YEAH
}
这是堆栈跟踪
