I have a CustomListView, when I longClick on a row, the layout of that row changes to a different listRow Layout. So far, everything is working, however, the layout of the new view is compressed. Here are my xml files:
search_result_layout.xml --> this is the original xml file used by the customListView Adapter.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/search_result_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:minHeight="50dp"
android:orientation="horizontal"
android:padding="1dip" >
<TextView
android:id="@+id/dialogItemName"
android:layout_width="0dp"
android:layout_weight="0.54"
android:layout_marginRight="5dp"
android:layout_height="match_parent"
android:text="Item Name"
android:gravity="center"
android:textSize="10pt" />
<TextView
android:id="@+id/price"
android:layout_width="0dp"
android:layout_weight="0.14"
android:layout_height="match_parent"
android:text="Price"
android:gravity="center"
android:textSize="10pt" />
<TextView
android:id="@+id/discount"
android:layout_width="0dp"
android:layout_weight="0.10"
android:layout_height="match_parent"
android:text="Discount"
android:gravity="center"
android:textSize="10pt" />
<TextView
android:id="@+id/qtyInput"
android:layout_width="0dp"
android:layout_weight="0.14"
android:layout_height="match_parent"
android:text="qtyInput"
android:gravity="center"
android:textSize="10pt" />
<TextView
android:id="@+id/discInput"
android:layout_width="0dp"
android:layout_weight="0.11"
android:layout_height="match_parent"
android:text="discInput"
android:gravity="center"
android:textSize="10pt" />
</LinearLayout>
Here is my search_result_inflate.xml file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:minHeight="50dp"
android:orientation="horizontal"
android:padding="1dip" >
<TextView
android:id="@+id/dialogItemName"
android:layout_width="0dp"
android:layout_weight="0.54"
android:layout_marginRight="5dp"
android:layout_height="match_parent"
android:text="Item Name"
android:gravity="center"
android:textSize="10pt" />
<TextView
android:id="@+id/price"
android:layout_width="0dp"
android:layout_weight="0.14"
android:layout_height="match_parent"
android:text="Price"
android:gravity="center"
android:textSize="10pt" />
<TextView
android:id="@+id/discount"
android:layout_width="0dp"
android:layout_weight="0.10"
android:layout_height="match_parent"
android:text="Discount"
android:gravity="center"
android:textSize="10pt" />
<EditText
android:id="@+id/qtyInput"
android:layout_width="0dp"
android:layout_weight="0.14"
android:layout_height="match_parent"
android:hint="qtyInput"
android:inputType="number"
android:gravity="center"
android:textSize="10pt" />
<EditText
android:id="@+id/discInput"
android:layout_width="0dp"
android:layout_weight="0.11"
android:layout_height="match_parent"
android:hint="discInput"
android:inputType="number|date"
android:gravity="center"
android:textSize="10pt" />
</LinearLayout>
The two files are almost identical, only that the last two TextViews become EditTexts instead so the user can input the values he or she wants.
Also, kindly notice that I placed weight in my textViews and EditTexts, so that the spaces are maximized when the user shifts the view from portrait to landscape.
resultListView.setOnItemLongClickListener(new OnItemLongClickListener() {
@Override
public boolean onItemLongClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
TextView textViewQuantity = (TextView)view.findViewById(R.id.qtyInput);
TextView textViewDiscountReq = (TextView)view.findViewById(R.id.discInput);
TextView textViewName = (TextView)view.findViewById(R.id.dialogItemName);
TextView textViewPrice = (TextView)view.findViewById(R.id.price);
TextView textViewDiscount = (TextView)view.findViewById(R.id.discount);
textViewQuantity.setVisibility(View.GONE);
textViewDiscountReq.setVisibility(View.GONE);
textViewName.setVisibility(View.GONE);
textViewPrice.setVisibility(View.GONE);
textViewDiscount.setVisibility(View.GONE);
LinearLayout ll_inflate = (LinearLayout)view.findViewById(R.id.search_result_layout);
Log.d("Angelo", "original width = " + ll_inflate.getWidth());
View child = getLayoutInflater().inflate(R.layout.search_result_inflate, null);
TextView newText = (TextView)child.findViewById(R.id.qtyInput);
newText.setText(textViewQuantity.getText().toString());
EditText enter_txt = (EditText)child.findViewById(R.id.qtyInput);
ll_inflate.addView(child);
Log.d("Angelo", "not original width = " + ll_inflate.getWidth());
return false;
}
});
When the I longClick an item, the layout changes. However, the TextViews and the EditTexts are all next to one another, as if the weight property was ignored. At first I thought that the width might have changed before and after the view was changed, but the Log told me it had 1136 width (I'm using a 2nd Gen Nexus 7). Now I'm blank, the width of the parent didn't change but the weight value was ignored. How do I fix this? Would assigning the weight programmatically a viable solution?
Also, follow up question, I only want the last 2 TextViews to change to EditTexts. So what I try to do to achieve that effect is that from the original layout, I pull the values of the first 3 fields (Item Name, Price, Discount) by doing textView.getText().toString() and get the textviews from the new layout and use setText() but so far, it did not work, any suggestions?
UPDATE:
Upon reading this link, I think that the Weight property of the TextViews inside the LinearLayout is being ignored when I use the LinearLayout as my ListView Row View. Nesting another Linear Layout did not help much either.
I placed another LinearLayout inside as such:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:minHeight="50dp"
android:orientation="horizontal"
android:padding="1dip" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:padding="1dip" >
<TextView
android:id="@+id/dialogItemName"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_marginRight="5dp"
android:layout_weight="0.70"
android:gravity="center"
android:text="Item Name"
android:textSize="23sp" />
<TextView
android:id="@+id/price"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="0.16"
android:gravity="center"
android:text="Price"
android:textSize="23sp" />
<TextView
android:id="@+id/discount"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="0.12"
android:gravity="center"
android:text="Discount"
android:textSize="23sp" />
<EditText
android:id="@+id/qtyInput"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="0.16"
android:gravity="center"
android:hint="qtyInput"
android:inputType="number"
android:textSize="23sp" >
<requestFocus />
</EditText>
<EditText
android:id="@+id/discInput"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="0.13"
android:gravity="center"
android:hint="discInput"
android:inputType="number|date"
android:textSize="23sp" />
</LinearLayout>
</LinearLayout>
Any ideas?
