将另一个EditText值插入Android的数据库？

Question

我有下面的代码，我相信设置我的数据库。一切正常，但它只允许我插入一个编辑文本值，然后显示在列表视图中。

理想情况下，我想添加时间和另一个编辑文本字段到数据库任何人都可以请帮助我。

SQLiteOpenHelper

public class TaskDBHelper extends SQLiteOpenHelper { 

public TaskDBHelper(Context context) { 
    super(context, TaskContract.DB_NAME, null, TaskContract.DB_VERSION); 
} 

@Override 
public void onCreate(SQLiteDatabase sqlDB) { 

    String sqlQuery = 
      String.format("CREATE TABLE %s (" + 
          "_id INTEGER PRIMARY KEY AUTOINCREMENT, " + 
          "%s TEXT)", TaskContract.TABLE, 
        TaskContract.Columns.TASK); 



    Log.d("TaskDBHelper", "Query to form table: " + sqlQuery); 

    sqlDB.execSQL(sqlQuery); 
} 

@Override 
public void onUpgrade(SQLiteDatabase sqlDB, int i, int i2) { 
    sqlDB.execSQL("DROP TABLE IF EXISTS "+TaskContract.TABLE); 
    onCreate(sqlDB); 
} 

}

MainActivity哪些更新UI等，对话框工作正常

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_meds2); 

    updateUI(); 

    FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); 
    fab.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 


      AlertDialog.Builder builder = new AlertDialog.Builder(Meds2.this); //start builder 

      LayoutInflater inflater = Meds2.this.getLayoutInflater(); 
      final View dialogView = inflater.inflate(R.layout.alert_box, null); 
      builder.setView(dialogView); 
      final EditText edt = (EditText) dialogView.findViewById(R.id.edit1); 
      final EditText edt2 = (EditText) dialogView.findViewById(R.id.edit2); 


      builder.setTitle("Add a task"); 
      builder.setMessage("What do you want to do?"); 

      // final EditText inputField = new EditText(Meds2.this); 
      // final EditText inputField2 = new EditText(Meds2.this); 
      // builder.setView(inputField); 
      // builder.setView(inputField2); 


      builder.setPositiveButton("Add", new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialogInterface, int i) { 


        String task = edt.getText().toString(); //retrieve vales from fields 
        String task2 = edt2.getText().toString(); 

        TaskDBHelper helper = new TaskDBHelper(Meds2.this); 


        SQLiteDatabase db = helper.getWritableDatabase(); 
        ContentValues values = new ContentValues(); 

        values.clear(); 
        values.put(TaskContract.Columns.TASK, task); //place values in db 
        values.put(TaskContract.Columns.TASK, task2); 


        db.insertWithOnConflict(TaskContract.TABLE, null, values, 
          SQLiteDatabase.CONFLICT_IGNORE); 

        updateUI(); //refresh list view 
       } 
      }); 

      builder.setNegativeButton("Cancel", null); 

      builder.create().show(); 
     } 
    }); 


    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); 
    navigationView.setNavigationItemSelectedListener(this); 

    SQLiteDatabase sqlDB = new TaskDBHelper(this).getWritableDatabase(); 
    Cursor cursor = sqlDB.query(TaskContract.TABLE, 
      new String[]{TaskContract.Columns.TASK}, 
      null,null,null,null,null); 

    cursor.moveToFirst(); 
    while(cursor.moveToNext()) { 
     Log.d("MainActivity cursor", 
       cursor.getString(
         cursor.getColumnIndexOrThrow(
           TaskContract.Columns.TASK))); 
    } 
} 

private ListAdapter listAdapter; 

public void onDoneButtonClick(View view) { 
    View v = (View) view.getParent(); 
    TextView taskTextView = (TextView) v.findViewById(R.id.taskTextView); 
    String task = taskTextView.getText().toString(); 

    String sql = String.format("DELETE FROM %s WHERE %s = '%s'", 
      TaskContract.TABLE, 
      TaskContract.Columns.TASK, 
      task); 


    helper = new TaskDBHelper(Meds2.this); 
    SQLiteDatabase sqlDB = helper.getWritableDatabase(); 
    sqlDB.execSQL(sql); 
    updateUI(); 
} 

private void updateUI() { 
    helper = new TaskDBHelper(Meds2.this); 
    SQLiteDatabase sqlDB = helper.getReadableDatabase(); 
    Cursor cursor = sqlDB.query(TaskContract.TABLE, 
      new String[]{TaskContract.Columns._ID, TaskContract.Columns.TASK}, 
      null, null, null, null, null); 

    listAdapter = new SimpleCursorAdapter(
      this, 
      R.layout.task_view, 
      cursor, 
      new String[]{TaskContract.Columns.TASK}, 
      new int[]{R.id.taskTextView}, 
      0 
    ); 

    this.setListAdapter(listAdapter); 
} 

自定义列表视图布局

<RelativeLayout 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
xmlns:android="http://schemas.android.com/apk/res/android"> 

<TextView 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="New Text" 
    android:id="@+id/taskTextView" 
    android:layout_alignParentTop="true" 
    android:layout_alignParentLeft="true" 
    android:layout_alignParentStart="true" 
    android:textSize="20dp" 
    android:layout_toLeftOf="@+id/doneButton" 
    android:layout_alignBottom="@+id/doneButton" 
    android:gravity="center_vertical" /> 

<Button 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="Delete" 
    android:id="@+id/doneButton" 
    android:layout_alignParentTop="true" 
    android:layout_alignParentRight="true" 
    android:layout_alignParentEnd="true" 
    android:onClick="onDoneButtonClick"/> 

<TextView 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="New Text" 
    android:id="@+id/time" 
    android:textSize="20dp" 
    android:layout_marginLeft="94dp" 
    android:layout_marginStart="94dp" 
    android:layout_alignBottom="@+id/taskTextView" 
    android:layout_alignParentTop="true" 
    android:layout_alignParentLeft="true" 
    android:layout_alignParentStart="true" 
    android:layout_toRightOf="@+id/doneButton" 
    android:gravity="center_vertical" 
    /> 

Answer 1

做到这一点

//insert first edittext value 
values.put(TaskContract.Columns.TASK, task); 
db.insertWithOnConflict(TaskContract.TABLE, null, values,SQLiteDatabase.CONFLICT_IGNORE); 

values.clear(); 

//insert seco edittext value 
values.put(TaskContract.Columns.TASK, task2); 
db.insertWithOnConflict(TaskContract.TABLE, null, values,SQLiteDatabase.CONFLICT_IGNORE);
