为什么我不能读取我的数据库？

Question

我可以在我的数据库中插入信息，但是当我想在插入它之后像阅读developer.android一样阅读它们时，它将与此错误关闭，“不幸的是，应用程序已停止”。
这是我的代码：

FeedReaderDbHelper mDbHelper = new FeedReaderDbHelper(getApplicationContext()); 
SQLiteDatabase db = mDbHelper.getWritableDatabase(); 
ContentValues values = new ContentValues(); //for insert 
Date now=new Date(); //for insert 
values.put("ID", 1); //for insert 
values.put("kalame", "good"); //for insert 
values.put("mani", "salam"); //for insert 
values.put("marhale", "1"); //for insert 
values.put("taghir", String.valueOf(now.getTime())); //for insert 

long newRowID=db.insert("english", "taghir" , values); //for insert 

String[] meghdarha={"good"}; 
String[] sotoonha={"ID","kalame","mani","marhale","taghir"}; 
Cursor nowRead =db.query("english", sotoonha, "kalame = good", null, null, null, null); 

nowRead.moveToFirst(); 
long newWord=nowRead.getLong(nowRead.getColumnIndexOrThrow("ID")); 
TextView tv= (TextView)findViewById(R.id.textView1); 
tv.setText(String.valueOf(newWord)); 

这是我FeedReaderDbHelper：

public class FeedReaderDbHelper extends SQLiteOpenHelper { 

    // If you change the database schema, you must increment the database version. 
    public static final int DATABASE_VERSION = 1; 
    public static final String DATABASE_NAME = "FeedReader.db"; 
    public static final String sakht="CREATE TABLE english (ID INTEGER PRIMARY KEY,kalame TEXT,mani TEXT,marhale TEXT,taghir TEXT);"; 
    public static final String pak="DROP TABLE IF EXISTS english"; 

    public FeedReaderDbHelper(Context context) { 
     super(context, DATABASE_NAME, null, DATABASE_VERSION); 
    } 

    public void onCreate(SQLiteDatabase db) { 
     db.execSQL(sakht); 
    } 

    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
     // This database is only a cache for online data, so its upgrade policy is 
     // to simply to discard the data and start over 
     db.execSQL(pak); 
     onCreate(db); 
    } 

    public void onDowngrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
     onUpgrade(db, oldVersion, newVersion); 
    }  
} 

这是我的日志猫：

我该如何解决？
请帮我请

Answer 1

不知道是否这是问题，但你创建表查询是缺少“）;”

你有

public static final String sakht="CREATE TABLE english (ID INTEGER PRIMARY KEY,kalame TEXT,mani TEXT,marhale TEXT,taghir TEXT"; 

，但它应该是

public static final String sakht="CREATE TABLE english (ID INTEGER PRIMARY KEY,kalame TEXT,mani TEXT,marhale TEXT,taghir TEXT);"; 

而且您的查询是错误的。您可以做

Cursor nowRead =db.query("english", sotoonha, "kalame = good", null, null, null, null); 

或更动态

Cursor nowRead =db.query("english", sotoonha, "kalame = ?", meghdarha, null, null, null); 

请查看以下职位的详细信息 How to pass two or more selection argument in "query" method

Answer 2

“约束失败”与您的主键来执行。您正在试图插入行具有重复“ID”

当您创建表：

CREATE TABLE english (ID INTEGER PRIMARY KEY,kalame TEXT,mani TEXT,marhale TEXT,taghir TEXT);" 

你是在告诉列“ID”不能有重复的值的SQLite。当您重新启动应用程序，你的数据库已经存在，你正试图插入具有“ID = 1”，在这里再次行：

long newRowID=db.insert("english", "taghir" , values); //for insert
