Remove layout on a button click programmatically in android studio-CodePudding

The

As you can see in the above image I have added 4-5 layouts of the product but when I click the remove button I remove all the layouts.

Update 1

I have added the below layout in my main layout and then called the product layout inside it programatically

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@ id/ll_prod" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > </LinearLayout>

The product layout is created separately and I am calling it in my main layout.

<?xml version="1.0" encoding="utf-8"?>  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <LinearLayout android:id="@ id/ll_out" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@drawable/background_round" android:orientation="vertical" android:padding="5sp"> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:layout_marginTop="10sp" android:orientation="horizontal"> <AutoCompleteTextView android:id="@ id/tv_product" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="left|center_vertical" android:gravity="left" android:hint="Enter Product" android:inputType="text" /> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="10sp" android:orientation="horizontal"> <LinearLayout android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight=".5" android:orientation="vertical"> <EditText android:id="@ id/prod_qty" android:layout_width="match_parent" android:layout_height="wrap_content" android:editable="false" android:focusable="true" android:focusableInTouchMode="true" android:hint="Enter Quantity" android:gravity="left" android:inputType="number" /> </LinearLayout> <LinearLayout android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight=".5" android:orientation="vertical"> <EditText android:id="@ id/prod_price" android:layout_width="match_parent" android:layout_height="wrap_content" android:editable="false" android:focusable="false" android:focusableInTouchMode="false" android:hint="Prod Price" android:gravity="left" android:inputType="none" /> </LinearLayout> <LinearLayout android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight=".5" android:orientation="vertical"> <EditText android:id="@ id/prod_specs" android:layout_width="match_parent" android:layout_height="wrap_content" android:editable="false" android:focusable="false" android:focusableInTouchMode="false" android:gravity="left" android:hint="Prod Specs" android:inputType="none" /> </LinearLayout> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginBottom="1dp" android:layout_marginTop="1dp" android:padding="0dp"> <Button android:id="@ id/btn_rmv" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Remove Product" android:textColor="@color/white" /> </LinearLayout> </LinearLayout>

The above layout is called whenever I click on Add New Product Button.

How can I remove a particular layout??

Any help would be highly appreciated.

CodePudding user response：

It's because you are removing the entire layout instead you should remove layout been added dynamically I'm supposing that remove product is a direct child in product_layout main view group

removeProduct.setOnClickListener(v -> { if (mLinearLayout.getChildCount()>0) { ((LinearLayout)mLinearLayout.getParent()).removeView(removeProduct.getParent()); } });}

But you should keep in mind that this is totally not recommended and instead you should use recyclerview and on adding new product add an object to products list and call notifyDataSetChanged(), also you can use System.currentTimeMillis() as a unique id for product object.

I think @Islam Assem approch is right and for your error, i think it should be solved with type casting like this:

removeProduct.setOnClickListener(v -> { if (mLinearLayout.getChildCount()>0) { ((LinearLayout)mLinearLayout.getParent()).removeView((ViewGroup)removeProduct.getParent().getParent()); } }); }

and also can you shere XML of your product_layout file, so I can see who is the real parent of removeProduct, is it a new layout or a main one.
