sqlite数据库只插入一列数据

Question

所以我使用多个 radiogroup 和一个 EditText 将数据插入数据库。问题是只插入了一列数据，而且它始终是 collection_time 列。

这是插入数据的编码：

    BtnNext1.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
   Intent intent = new Intent(SelectPrintingDetails.this, Summary.class);

                    int selectedId = rgCP.getCheckedRadioButtonId();
                    if(selectedId != -1)
                    {
                        RadioButton selectedRadioButton = (RadioButton) findViewById(selectedId);
                        String rbCP = selectedRadioButton.getText().toString();
                        Boolean insertPD = db.insertcolor(rbCP);
                        if(insertPD == true)
                        {
                            intent.putExtra("Color", rbCP);
                        }
                        else
                        {
                            Toast.makeText(getApplicationContext(), "Data is not inserted",Toast.LENGTH_SHORT).show();
                        }

                    }
                    else
                    {
                        Toast.makeText(getApplicationContext(), "Radiobutton is not selected",Toast.LENGTH_SHORT).show();
                    }

                    int selectedId1 = rgFP.getCheckedRadioButtonId();
                    if(selectedId1 != -1)
                    {
                        RadioButton selectedRadioButton = (RadioButton) findViewById(selectedId1);
                        String rbFP = selectedRadioButton.getText().toString();
                        Boolean insertPD1 = db.insertflip(rbFP);
                        if(insertPD1 == true)
                        {
                            intent.putExtra("Flip", rbFP);
                        }
                        else
                        {
                            Toast.makeText(getApplicationContext(), "Data is not inserted",Toast.LENGTH_SHORT).show();
                        }

                    }
                    else
                    {
                        Toast.makeText(getApplicationContext(), "Radiobutton is not selected",Toast.LENGTH_SHORT).show();
                    }

                    int selectedId2 = rgPC.getCheckedRadioButtonId();
                    if(selectedId1 != -1)
                    {
                        RadioButton selectedRadioButton = (RadioButton) findViewById(selectedId2);
                        String rbPC = selectedRadioButton.getText().toString();
                        Boolean insertPD2 = db.insertpc(rbPC);
                        if(insertPD2 == true)
                        {
                            intent.putExtra("Plastic", rbPC);
                        }
                        else
                        {
                            Toast.makeText(getApplicationContext(), "Data is not inserted",Toast.LENGTH_SHORT).show();
                        }

                    }
                    else
                    {
                        Toast.makeText(getApplicationContext(), "Radiobutton is not selected",Toast.LENGTH_SHORT).show();
                    }

                    int selectedId3 = rgBind.getCheckedRadioButtonId();
                    if(selectedId1 != -1)
                    {
                        RadioButton selectedRadioButton = (RadioButton) findViewById(selectedId3);
                        String rbBind = selectedRadioButton.getText().toString();
                        Boolean insertPD3 = db.insertbind(rbBind);
                        if(insertPD3 == true)
                        {
                            intent.putExtra("Bind", rbBind);
                        }
                        else
                        {
                            Toast.makeText(getApplicationContext(), "Data is not inserted",Toast.LENGTH_SHORT).show();
                        }

                    }
                    else
                    {
                        Toast.makeText(getApplicationContext(), "Radiobutton is not selected",Toast.LENGTH_SHORT).show();
                    }



                    String timecollect = etCT.getText().toString();
                    Boolean insertPD4 = db.insertct(timecollect);
                    if(insertPD4 == true)
                    {
                        intent.putExtra("Collect", timecollect);
                    }
                    else
                    {
                        Toast.makeText(getApplicationContext(), "Data is not inserted",Toast.LENGTH_SHORT).show();
                    }


                    startActivity(intent);
                }
            });

这是数据库助手：

public class DatabaseHelper extends SQLiteOpenHelper {
    public DatabaseHelper(Context context) {
        super(context, "hdatabase1.db", null, 1);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {


        db.execSQL("Create table printingdetails (color text, binding text, collection_time text, flipped_page text, plastic_cover text)");


    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int i, int i1) {


        db.execSQL("drop table if exists printingdetails");
    }


    public boolean insertcolor(String color)
        {
            SQLiteDatabase db = this.getWritableDatabase();
            ContentValues contentValues = new ContentValues();
            contentValues.put("color", color);

            long ins = db.insert("printingdetails", null, contentValues);
            if(ins==-1) return false;
            else return true;

        }

        public boolean insertflip(String flipped_page)
        {
            SQLiteDatabase db = this.getWritableDatabase();
            ContentValues contentValues = new ContentValues();
            contentValues.put("flipped_page", flipped_page);

            long ins = db.insert("printingdetails", null, contentValues);
            if(ins==-1) return false;
            else return true;

        }

        public boolean insertpc(String plastic_cover)
        {
            SQLiteDatabase db = this.getWritableDatabase();
            ContentValues contentValues = new ContentValues();
            contentValues.put("plastic_cover", plastic_cover);

            long ins = db.insert("printingdetails", null, contentValues);
            if(ins==-1) return false;
            else return true;

        }

        public boolean insertbind(String binding)
        {
            SQLiteDatabase db = this.getWritableDatabase();
            ContentValues contentValues = new ContentValues();
            contentValues.put("binding", binding);

            long ins = db.insert("printingdetails", null, contentValues);
            if(ins==-1) return false;
            else return true;

        }

        public boolean insertct (String collection_time)
        {
            SQLiteDatabase db = this.getWritableDatabase();
            ContentValues contentValues = new ContentValues();
            contentValues.put("collection_time", collection_time);

            long ins = db.insert("printingdetails", null, contentValues);
            if(ins==-1) return false;
            else return true;

        }

希望大家指导我如何在每一列中插入所有数据。我还是新手，我已经在这里参考了几个相关的 post，其中 none 确实对

有帮助

目前您似乎是分别插入每一列的值。这意味着您最终得到的不是单行，而是多行，其中只有一列有值，其余为空。

为了解决这个问题，您需要一个类似这样的方法：

public boolean insertRow(String color, String binding, String time, String flipped_page, String plastic_cover) {
    SQLiteDatabase db = this.getWritableDatabase();
    ContentValues contentValues = new ContentValues();
    contentValues.put("color", color);
    contentValues.put("binding", binding);
    contentValues.put("collection_time", time);
    contentValues.put("flipped_page", flipped_page);
    contentValues.put("plastic_cover", plastic_cover);

    long ins = db.insert("printingdetails", null, contentValues);
    if(ins==-1) return false;
    else return true;
}

应删除每个单独的插入命令。现在，您的 onClick 方法必须检索所有选定的项目，然后调用此插入方法。未选择的无线电组的处理将取决于您的应用程序。在下面的示例中，我只是中断了方法，从而取消了提交。如果某些单选组是可选的，那么可以将相应的字符串设置为空（""）并继续该方法，而不是通过返回取消提交。

public void onClick(View v) {

    Intent intent = new Intent(SelectPrintingDetails.this, Summary.class);
    String color, binding, time, page, cover;

    int selectedId = rgCP.getCheckedRadioButtonId();
    if(selectedId != -1)
    {
        RadioButton selectedRadioButton = (RadioButton) findViewById(selectedId);
        color = selectedRadioButton.getText().toString();    
    }
    else
    {
        Toast.makeText(getApplicationContext(), "Color is not selected",Toast.LENGTH_SHORT).show();
        return; // this prevents the rest of the code from executing
    }

    int selectedId1 = rgFP.getCheckedRadioButtonId();
    if(selectedId1 != -1)
    {
        RadioButton selectedRadioButton = (RadioButton) findViewById(selectedId1);
        page = selectedRadioButton.getText().toString();
    }
    else
    {
        Toast.makeText(getApplicationContext(), "FlipPage is not selected",Toast.LENGTH_SHORT).show();
        return;
    }

    int selectedId2 = rgPC.getCheckedRadioButtonId();
    if(selectedId2 != -1)
    {
        RadioButton selectedRadioButton = (RadioButton) findViewById(selectedId2);
        cover = selectedRadioButton.getText().toString();
    }
    else
    {
        Toast.makeText(getApplicationContext(), "Plastic Cover is not selected",Toast.LENGTH_SHORT).show();
        return;
    }

    int selectedId3 = rgBind.getCheckedRadioButtonId();
    if(selectedId3 != -1)
    {
        RadioButton selectedRadioButton = (RadioButton) findViewById(selectedId3);
        binding = selectedRadioButton.getText().toString();
    }
    else
    {
        Toast.makeText(getApplicationContext(), "Binding is not selected",Toast.LENGTH_SHORT).show();
        return;
    }

    time = etCT.getText().toString();

    // since all attributed have been read, now we call insert
    // you can read the returned boolean to determine if the insertion was successful
    db.insertRow(color, binding, time, page, cover);

    // Also add all of them as intent extras
    intent.putExtra("Color", color);
    intent.putExtra("Bind", binding);
    intent.putExtra("Collect", time);
    intent.putExtra("Flip", page);
    intent.putExtra("Plastic", cover);

    startActivity(intent);
}

我希望这能帮助您了解哪里出了问题，以及您如何才能继续前进。
