java - 我想在 onCreate 期间使子线性布局不可见，然后通过点击按钮使其可见

Question

XML Layout Here这是我的布局。我希望按钮之后的所有内容在点击按钮之前都是不可见的。

/**
     * This activity toggles open the order_form layout AFTER "Order" Button is clicked.
     */
    Button properties = (Button) findViewById(R.id.order_button);

// and LinearLayout to toggle
    final LinearLayout propLayout = (LinearLayout) findViewById(R.id.order_form);

    properties.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            propLayout.setVisibility((propLayout.getVisibility() == View.VISIBLE)
                    ? View.INVISIBLE
                    : View.VISIBLE);
        }
    });

Answer 1

xml 中的位置和可见性属性像这样

android:visibility="invisible"

<LinearLayout
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:orientation="vertical"
  android:visibility="invisible">

   <-- edittext views here-->
   <EditText
      ......./>
</LinerLayout>
