我有一個插入條目邏輯到我的android應用程序，它是完全響應，直到我上次訪問應用程序。 但它突然開始停止響應和運行。所以，請幫助我在我的邏輯中犯了什麼錯誤或錯誤，或者在我的編碼中突然響應sqlite以這種方式行事的問題。 請儘快幫助我，因爲我今天有最終的android應用程序演示文稿，而且我很少花時間省略。突然Android應用程序開始停止共鳴
在此先感謝您的幫助。
問候:)
繼我創建表的邏輯：
private static final int DATABASE_VERSION = 1; // db version
private static final String DATABASE_NAME = "db_Blood_Donation"; // db name
private static final String TABLE_NAME = "Table1"; // table name
// table fields
private static final String KEY_ID = "bid";
private static final String KEY_NAME = "bname";
private static final String KEY_DATE = "bdate";
private static final String KEY_GRP = "bgroup";
private static final String KEY_ADD = "baddress";
private static final String KEY_PH = "bphno";
public DBHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
// TODO Auto-generated constructor stub
}
@Override
public void onCreate(SQLiteDatabase db) {
// TODO Auto-generated method stub
/* ------------- CREATE TABLE ------------- */
String CREATE_TABLE1 = "CREATE TABLE " + TABLE_NAME + "(" + KEY_ID
+ "INTEGER PRIMARY KEY, " + KEY_NAME + "TEXT, " + KEY_DATE
+ "TEXT, " + KEY_GRP + "TEXT, " + KEY_ADD + "TEXT, " + KEY_PH
+ "TEXT " + ")";
db.execSQL(CREATE_TABLE1);
Log.d("Table_Created", "table1");
}
以下是我的AddEntry邏輯：
/* ----------------- ADD USER ------------- */
void addUser(BDFieldClass user) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues cv = new ContentValues();
cv.put(KEY_NAME, user.getBname());
cv.put(KEY_DATE, user.getBdate());
cv.put(KEY_GRP, user.getBgroup());
cv.put(KEY_ADD, user.getBaddress());
cv.put(KEY_PH, user.getPhno());
// INSERT ROWS
db.insertOrThrow(TABLE_NAME, null, cv);
db.close();
}
下面是我打電話是我的插入邏輯的代碼：
/* ------------------------------- ADD RECORED ----------- ------- -------------- */
btnadd.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
// TODO Auto-generated method stub
EditText ednm = (EditText)findViewById(R.id.txtname);
String name = ednm.getText().toString();
eddate = (EditText)findViewById(R.id.txtdate);
String date1 = eddate.getText().toString();
EditText edadd = (EditText)findViewById(R.id.txtadd);
String add = edadd.getText().toString();
EditText edno = (EditText)findViewById(R.id.txtno);
String phno = edno.getText().toString();
dbh.addUser(new BDFieldClass(name,date1,bgrp,add,phno));
以下是logcat的錯誤：

您應該發佈堆棧跟蹤。它比代碼更重要。 – wtsang02
