推荐答案

给该布局一个 id 例如...

Give that layout an id such as...

<LinearLayout   
    android:id="@+id/check_add_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/feedbackPlansCheckBoxLL"
    android:orientation="horizontal" >
    <!--
        Required to Add CheckBoxes Here Dynamically
    -->
</LinearLayout>

使用给定的 id 初始化父布局...

Initialize a parent layout using the given id as...

LinearLayout parentLayout = (LinearLayout) findViewById(R.id.check_add_layout);

然后创建您的复选框...

Then create your CheckBox...

CheckBox checkBox = new CheckBox(this);
checkBox.setId(id);
checkBox.setText("text");

创建有关其大小、填充、对齐方式的参数...

Create parameters about its size, padding, alignment...

LinearLayout.LayoutParams checkParams = new LinearLayout.LayoutParams(
                LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
checkParams.setMargins(10, 10, 10, 10);
checkParams.gravity = Gravity.CENTER;

现在将这个新创建的 CheckBox 添加到该父布局...

now add this newly created CheckBox to the that parent layout...

parentLayout.addView(checkBox, checkParams);
