点击是在项目中给出错误 [英] on click is giving error in project

问题描述

我正在开发一个应用程序项目，我想在其中创建一个数据库，并将在editText中输入的一些细节添加到表中。点击OnBtnIncludeClick按钮后，我收到一条错误消息不幸的是，应用程序已停止。我可以在editText中输入一些文字。

I am developing an apps project in which I want to create a database and add some details entered in editText into a table. On click of button 'OnBtnIncludeClick' I get an error stating 'Unfortunately, apps has stopped'. I am able to enter some text in editText.

public class listmasteritems extends Activity implements OnClickListener{
public EditText editText;
    SQLiteDatabase db;
    String AccountName;

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_listmasteritems);
        editText = (EditText)findViewById(R.id.idRelationShip);
        editText.setOnClickListener(this);
    db=openOrCreateDatabase("myDb",MODE_PRIVATE,null);
    db.execSQL("CREATE TABLE IF NOT EXISTS TblAccountMaster (AccountId int primary key, AccountName varchar ) ");

    }

    public void onBtnIncludeClick( View v)
    {
        AccountName=editText.getText().toString();
        db.execSQL( "INSERT INTO TblAccountMaster VALUES('"+AccountName+"');");
        db.close();

    }
