[英]Add and replace one fragment with another on button click
我有兩個片段,WishlistFragment和GoShoppingFragment和一個按鈕“ Continue Shopping”。 在按鈕上單擊我希望將WishlistFragment替換為GoShoppingFragment。
這是onClick的實現。
public void onClickShopNow() {
FragmentManager fragmentManager = getFragmentManager();
Fragment fragment = new GoShoppingFragment();
fragmentManager
.beginTransaction()
.replace(R.id.container, fragment)
.addToBackStack(null)
.commit();
if(fragmentManager.getBackStackEntryCount() > 0) {
fragmentManager.popBackStackImmediate();
}
}
這里的問題是,當我點擊“繼續購物”,然后WishlistFragment被relaced GoShoppingFragment,但我得到的輸出喜歡這樣 。 WishlistFragment仍保留在后台。 我該如何解決這個問題?
GoShopping布局:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".ui.store.goshopping.GoShoppingFragment">
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/swipe_refresh_go_shopping"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone">
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_go_shopping"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.v4.widget.SwipeRefreshLayout>
<ProgressBar
android:id="@+id/progress_bar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:visibility="visible" />
<LinearLayout
android:id="@+id/moreLoading"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_alignParentBottom="true"
android:background="@color/transparent"
android:gravity="center"
android:orientation="horizontal"
android:visibility="gone">
<ProgressBar
android:id="@+id/moreLoadingIndicator"
style="?android:attr/progressBarStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginStart="10dp"
android:text="@string/label_loading_more" />
</LinearLayout></RelativeLayout>
心願單布局:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/container"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="io.launchbyte.appio.ui.store.mywishlist.MyWishlistFragment">
<LinearLayout
android:id="@+id/layout_continue_shopping"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:orientation="vertical"
android:visibility="gone">
<TextView
android:id="@+id/txt_wishlist_empty"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:padding="8dp"
android:text="@string/wishlist_empty" />
<TextView
android:id="@+id/txt_wishlist_add_items"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:padding="8dp"
android:text="@string/wishlist_add_items" />
<Button
android:id="@+id/button_continue_shopping"
android:layout_width="150dp"
android:layout_height="48dp"
android:layout_gravity="center"
android:layout_marginTop="24dp"
android:background="@drawable/primary_color_button_selector"
android:text="@string/continue_shopping" />
</LinearLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_my_wishlist"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fadeScrollbars="true"
android:visibility="gone" />
<ProgressBar
android:id="@+id/progress_bar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:visibility="visible" />
</RelativeLayout></FrameLayout>
設置片段的背景,並在每個片段xml中設置setClickable(true)。
在父級布局中將背景色設置為白色可解決此問題。
刪除此:
if(fragmentManager.getBackStackEntryCount() > 0) {
fragmentManager.popBackStackImmediate();
}
同樣在您的GoShopping layout:
在根標記中添加:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true"
android:background="?android:attr/windowBackground"
tools:context=".ui.store.goshopping.GoShoppingFragment">
public void onClickShopNow() {
FragmentManager fragmentManager = getFragmentManager();
Fragment fragment = new GoShoppingFragment();
Fragment WishlistFragment =
fragmentManager.getFragmentByTag("TagName");
fragmentManager
.beginTransaction()
.remove(WishlistFragment)
.commit();
fragmentManager
.beginTransaction()
.add(R.id.container, fragment,"TagHere")
.commit();
}
希望對您有幫助。
