Question

我想在我的数据库中填充一个Android应用程序，但我不知道我是否做得很好。所以我想在这里寻求一点帮助

这是我的DB代码

public long createData() {
    // TODO Auto-generated method stub
    String [] arg = new String [] {"Abdullah", "Abdulatif","Abdulaziz","Abdulbaki","Zafir"};
    String [] mng = new String [] { "Adhurues; Rob i Zotit", "Adhurues i Zotit Ledhatues","Adhurues i Zotit Fuqiplotë","Adhurues i Zotit të përhershëm","Fitimtar"};
    String [] gnr = new String [] {"Mashkull", "Mashkull","Mashkull", "Mashkull", "Mashkull"};
    ContentValues cv = new ContentValues();
    for (int i = 0; i < arg.length; i++){
        cv.put(KEY_EMRI, arg[i]);

        cv.put(KEY_KUPTIMI, mng[i]);


        cv.put(KEY_GJINIA, gnr[i]);
        ourDatabase.insert(DATABASE_TABLE, null, cv);
    }
    return  ourDatabase.insert(DATABASE_TABLE, null, cv);

}

这是我在java文件中创建的方法onCreate，我想显示来自DB的结果

    protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.meshkuj);

    search = (Button) findViewById(R.id.bKerko);
    etSearch = (EditText) findViewById(R.id.etKerko);
    tvName = (TextView) findViewById(R.id.tvEmr);
    tvGenre = (TextView) findViewById(R.id.tvGjinia);
    tvMeaning = (TextView) findViewById(R.id.tvKuptimi);
    emri = (TextView) findViewById(R.id.tvShEmri);


    Emertimet info = new Emertimet(this);
    info.open();
    info.createData();
    info.close();           
}

所以我再次想知道填充DB或（createData）的任何其他方法，或者这个方法是好的。提前谢谢你

你做错了，因为

你是在主线程上做的（片段在这里：Correct use of Sqlite on Android (SQLiteOpenHelper, connections, main thread, etc...)）
您没有在交易（Android SQLite database: slow insertion）

在android中填充DB的更有效方法
