如何传递嵌套对话框片段中的数据

Question

我有一个对话框片段，它有六个按钮。当用户单击按钮时，颜色选择器打开。然后颜色数据传递给第一个对话框片段和单个颜色在按钮上设置。 Dialog Fragment 1。 问题是当我声明接口方法时，我能够获取片段或活动中的数据，但无法将数据获取到对话框片段1中。 如何将数据从对话框片段2传递到对话框片段1 ？

我想将被触及的RGB颜色传递给第一个对话框片段。

是否可以使用颜色模型中的getter和setter发送数据，如果是的话怎么做？

builder.setView(layout) 
      .setNegativeButton(R.string.cancel, 
        new DialogInterface.OnClickListener() { 
         @Override 
         public void onClick(DialogInterface dialog, int id) { 
          ColorDialog.this.getDialog().cancel(); 
          mListener.onDialogNegativeClick(ColorDialog.this);//calling the listener 

         } 
        }) 
      .setPositiveButton(R.string.ok, 
        new DialogInterface.OnClickListener() { 
         @Override 
         public void onClick(DialogInterface dialog, int id) { 
          ColorModel colormodel = new ColorModel(); 
          colormodel.setColorData(ColorData); 
          mListener.onDialogPositiveClick(ColorDialog.this); 
          mListener.receiveColorData(touchedRGB); //calling the listener 
         } 
        }); 
    return builder.create(); 
}

预先感谢您。

你只是实现了ColorDialog.ColorDialogListener，但你忘记了将ColorDialog设置回调。

对话片段1

ColorDialog dialogFragment = new ColorDialog(); 
dialogFragment.setCallBack(this); 
dialogFragment.show(getChildFragmentManager(), "ColorSelect"); 

ColorDialog类

public ColorDialog extends DialogFragment { 
    private ColorDialogListener mCallback; 

    public void setCallBack(ColorDialogListener listener) { 
     this.mCallback = listener; 
    } 

    public interface ColorDialogListener { 
      public void onColorSelect(ColorModel model); 
    } 

    /** Now you call back is ready to send data**/ 
    mCallback.onColorSelect(colorModel) 
}
