无法启动活动：android.database.sqlite.SQLiteException

Question

我正在编写一个应用程序来点击按钮阅读圣经，我想将圣经存储在SQLight数据库中并使用应用程序将其加载到设备中，以便用户即使在离线时也可以访问圣经。程序不加载活动（在我创建表并尝试从中读取之前它是完美的），它还说package com.example.roopa.jesus; import android.content.Intent; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.view.View; public class choosingTestament extends AppCompatActivity { private View v; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_choosing_testament); // View view = findViewById(android.R.id.button1); //view = findViewById(android.R.id.button2); } public void onClickOldTestament(View v) { Intent i = new Intent(choosingTestament.this, ChooseBook.class); startActivity(i); } public void onClickNewTestament(View v){ Intent i2 = new Intent(choosingTestament.this, choosingNewTestamentBook.class); startActivity(i2); } } 附近有语法错误。以下是我的源代码

        genesis = (Button) findViewById(R.id.genesis);

                    }

        builder.setTitle(title);
        builder.setMessage(Message);
        builder.show();
    }
}

// /cursor.close();
        //String query="SELECT * FROM"+TABLE_OLDTESTAMENT;
        //return data;



    /*@Override

        //dbHandler.printDatabase();
        String text = dbHandler.getYourData();
        dbHandler.close();

请帮我找错。

Answer 1

观看那些空间！您在CREATE TABLE语句中遗漏了一些您正在连接字符串的内容。你的陈述应该是：

String queryoldtest = ("CREATE TABLE " + OLDTESTAMENT + "(" +
            COLUMN_BOOK + " TEXT, " +
            COLUMN_CHAPTER + " TEXT,  " +
            COLUMN_VERSE + " TEXT, " +
            COLUMN_WORDING + " TEXT" +
            ");");

请注意三行之后TABLE之后和TEXT之前的新空格。出于同样的原因，您还需要在所有VALUES语句INSERT之前留出空格。

同样对于INSERT语句，您使用的是文字OLDTESTAMENT而不是变量，因此您需要将这些语句的开头更改为：

db.execSQL("INSERT INTO " + OLDTESTAMENT + 

更好的是，如果您计划在OLDTESTAMENT或其他表中插入大量经文，我建议为其创建一个功能，例如

private void insertIntoOldTestament(SQLiteDatabase db, String book, int chapter, 
        int verse, String wording) {

    final String toExec = String.format("INSERT INTO %s ", OLDTESTAMENT) +
            "[(COLUMN_BOOK, COLUMN_CHAPTER,COLUMN_VERSE,COLUMN_WORDING)] " +
            String.format("VALUES ('%s', '%d', '%d', '%s');", book, chapter, verse, wording);
    db.execSQL(toExec);
}

所以你可以这样做：

insertIntoOldTestament("GENESIS", 1, 1, "In the beginning God created heaven, and earth.");
insertIntoOldTestament("GENESIS", 1, 2, "And the earth was void and empty, and darkness was upon the face of the deep; and the spirit of God moved over the waters.");

等等，所以你只需要担心一次SQL语句。

（如果您对String.format()感到疑惑，那么在没有所有这些优点的情况下将变量插入字符串的方法就更好了;
