setVisibility（View.INVISIBLE）在 MapFragment 中不起作用

Question

我有一個具有展開和折疊功能的 map 片段。 因此，當我展開 map 時，我想隱藏 LinearLayout，而當我折疊時，我想顯示該布局。

但是setVisibility(View.INVISIBLE); 不工作。 當我調試應用程序時，我可以看到編譯器讀取了該行但仍然無法正常工作。

這是我的 XML 文件

Answer 1

我像這樣使用 LayoutParams 來隱藏一個接一個水平出現的元素：

LinearLayout.LayoutParams params_visible = new LinearLayout.LayoutParams(
    LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
layoutToBeVisible.setLayoutParams(params_visible);

LinearLayout.LayoutParams params_invisible = new LinearLayout.LayoutParams(
    0, LinearLayout.LayoutParams.WRAP_CONTENT);
layoutToBeInvisible.setLayoutParams(params_invisible);

LayoutParams 的第一個參數是寬度，第二個參數是高度。

Answer 2

在FrameLayout中覆蓋您的片段 xml 部分，然后在該 FrameLayout object 上的 Java 代碼調用 setVisibility()。

更新：

為了隱藏存儲在您的視圖組（即線性布局）下的視圖，請將您的線性布局與 Framelayout 作為父級包圍起來。

Answer 3

我找到了解決方法。 我將 Linearlayout 約束設置為屏幕外，因此它不再可見並以編程方式重新設置默認約束。

我所做的是在單擊展開按鈕時以編程方式向app:layout_constraintBottom_toTopOf="parent"添加設置約束。（當它展開時）

然后在折疊時以編程方式設置默認約束和邊距。

  app:layout_constraintBottom_toBottomOf="@+id/linearLayout"
  app:layout_constraintEnd_toEndOf="@+id/linearLayout"

這是解決方案的代碼

                mVib.vibrate(50);
                storageAccess.logMessage("Expand button click");

                constraintMap.clone(constraintLayout);
                constraintMap.clear(R.id.map, ConstraintSet.START);
                constraintMap.clear(R.id.map, ConstraintSet.TOP);
                constraintMap.applyTo(constraintLayout);
                constraintMap.connect(R.id.map, ConstraintSet.START, R.id.main_fragment_constraint_layout, ConstraintSet.START);
                constraintMap.connect(R.id.map, ConstraintSet.TOP, R.id.main_fragment_constraint_layout, ConstraintSet.TOP);
