                    android:visibility="invisible"
                    />

            <Button

                    android:layout_marginStart="8dp"
                    android:padding="10dp"
                    android:text="รายละเอียด"
                    android:background="#81C784"
                    android:src="@drawable/menu_complete"
                    android:scaleType="fitCenter"
                    />

        </RelativeLayout>

    </LinearLayout>

</android.support.v7.widget.CardView>

但是当我通过下面的代码通过膨胀XML文件动态地添加View（）时，它看起来像这样。似乎toLeftOf无效。

CODE

private void addCardView(int id, String type, String description) {
    View v = View.inflate(this, R.layout.listitem_complete_confirm, null);
    CheckBox ckbConfirm = (CheckBox) v.findViewById(R.id.ckbConfirm);
    TextView tvShipmentType = (TextView) v.findViewById(R.id.tvShipmentType);
    TextView tvShipmentDescription = (TextView) v.findViewById(R.id.tvShipmentDescription);
    TextView tvAlert = (TextView) v.findViewById(R.id.tvAlert);
    Button btnDetail = (Button) v.findViewById(R.id.btnDetail);

    tvShipmentType.setText(type);
    tvShipmentDescription.setText(description);
    btnDetail.setId(id);
    btnDetail.setOnClickListener(this);
    ckbConfirm.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            if (isChecked) {
                buttonView.setButtonDrawable(R.drawable.checkbox_default);
                tvAlert.setVisibility(View.INVISIBLE);
            }
        }
    });

    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
            LinearLayout.LayoutParams.MATCH_PARENT,
            LinearLayout.LayoutParams.WRAP_CONTENT
    );
    int margin = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 10, getResources().getDisplayMetrics());
    params.setMargins(margin, margin, margin, 0);
    llContainer.addView(v, params);
}

我怎样才能解决这个问题，似乎有些价值被忽略了扩充XML文件并使用addView（）。请指教。

这是一个更好的选择，因为我曾经weight代替高度或宽度的数字。

重量就像屏幕上的百分比一样，XML将适应任何屏幕分辨率。

Answer 2

当使用null参数进行充气时，将忽略布局参数。这就是你膨胀的方式：

View v = View.inflate(this, R.layout.listitem_complete_confirm, null);

使用父容器充气，不要追加。这看起来像这样：

View v = View.inflate(this, R.layout.listitem_complete_confirm, container/parentView, false);

您的容器或父视图必须是ViewGroup。

您需要更改.xml文件。
