Huge gap between imageview and textview

On my activity with fragments, I've some pages that have an image and some that don't. The layout is like this: Textview-Imageview-Textview, so when I there isn't an image I want the Textviews to be below each other. This is my XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#006400">
<ScrollView
android:layout_width="fill_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Text"
android:id="#+id/handling"
android:textColor="#ffffff"
android:textSize="20dp" />
<ImageView
android:layout_width="match_parent"
android:layout_height="200dp"
android:id="#+id/stilling"
android:layout_below="#id/handling"
android:layout_gravity="center_vertical" />
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textAlignment="center"
android:text="New Text"
android:id="#+id/arabisk"
android:layout_below="#id/stilling"
android:layout_gravity="center"
android:textSize="18dp"
android:textColor="#ff0000" />
</RelativeLayout>
</ScrollView>
</LinearLayout>
This is what I get
EDIT:
My array of images
int[] billede = new int[18];
billede[1] = R.mipmap.sojle1;
billede[2] = R.mipmap.sojle4;
billede[3] = R.mipmap.sojle2;
billede[4] = R.mipmap.sojle3;
billede[6] = R.mipmap.sojle4;
billede[8] = R.mipmap.sojle6;
billede[10] = R.mipmap.sojle7;
billede[12] = R.mipmap.sojle8;
billede[15] = R.mipmap.sojle9;
stilling.setImageResource(billede[mPage]);
return view;

Set the visiblity to GONE
in your xml
android:visibility="GONE"
or via code
imageView.setVisibility(View.GONE);

Set ImageView visibility to Gone and your text view must be one below other like you want. Like this
stilling.setVisibility(View.GONE);

Use LinearLayout instead of RelativeLayout. And set visible View.GONE to hide ImageView.

Android - Custom Keyboard on manually inflated listview row not showing

Good day.
I have an android application. In my application, I have a custom listView with 5 columns that are textViews. The user can click the rows, once he does, the row layout will change, changing the last 2 textViews to EditTexts. I then register the new EditTexts onto my custom keyboard taken from this example - kindly note that I did a functional copy-paste of his example with regards to the custom keyboard class and how to make it work in the main layout. However, when I click the EditText in the row, my custom keyboard does not show up at all.
I have a global variable as such:
CustomKeyboard mCustomKeyboard;
And in my onCreate() method in the activity, I do:
mCustomKeyboard= new CustomKeyboard(this, R.id.keyboardview, R.xml.custom_keyboard);
This is my layout, I have the KeyboardView at the bottom of the Layout:
<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:orientation="vertical"
android:paddingBottom="#dimen/activity_vertical_margin"
tools:context=".SearchResult" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<!-- A lot of views go here, enclosed in my linear layout -->
</LinearLayout>
<android.inputmethodservice.KeyboardView
android:id="#+id/keyboardview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:focusable="true"
android:focusableInTouchMode="true"
android:visibility="gone" />
</RelativeLayout>
Here is the code that changes the layout. What I do is that I take the row values from the old layout, get the new layout search_result_inflate, then set the texts of the new layout using the values I got. Kindly note the mCustomKeyboard.registerEditText(R.id.qtyInputSearchResult); line after inflating the layout:
private void changeLayout(final View view){
//get views from old layout
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);
//store values in strings
String itemName = textViewName.getText().toString();
String itemPrice = textViewPrice.getText().toString();
String itemDiscount = textViewDiscount.getText().toString();
String itemQty = textViewQuantity.getText().toString();
String itemDisc = textViewDiscountReq.getText().toString();
//set the view to gone
textViewQuantity.setVisibility(View.GONE);
textViewDiscountReq.setVisibility(View.GONE);
textViewName.setVisibility(View.GONE);
textViewPrice.setVisibility(View.GONE);
textViewDiscount.setVisibility(View.GONE);
//get the old layout
LinearLayout ll_inflate = (LinearLayout)view.findViewById(R.id.search_result_layout);
//get the inflate/new view
View child = getLayoutInflater().inflate(R.layout.search_result_inflate, null);
//get the views in the new view, populate them
TextView newName = (TextView)child.findViewById(R.id.dialogItemName);
newName.setText(itemName);
TextView newDiscount = (TextView)child.findViewById(R.id.discount);
newDiscount.setText(itemDiscount);
TextView newPrice = (TextView)child.findViewById(R.id.price);
newPrice.setText(itemPrice);
EditText qtyInput = (EditText)child.findViewById(R.id.qtyInputSearchResult);
qtyInput.setText(itemQty);
EditText discInput = (EditText)child.findViewById(R.id.discInputSearchResult);
discInput.setText(itemDisc);
//show new layout
ll_inflate.removeAllViews();
ll_inflate.removeAllViewsInLayout();
ll_inflate.addView(child);
mCustomKeyboard.registerEditText(R.id.qtyInputSearchResult);
}
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:id="#+id/search_result_inflate"

android:focusableInTouchMode="true"
android:gravity="center"
android:hint="discInput"
android:textColorHighlight="#color/white_opaque"
android:textSize="23sp" />
</LinearLayout>
</LinearLayout>
As you can see, I have 2 editTexts and I registered qtyInputSearchResult to the custom keyboard class. However, the custom keyboard does not show up.
I also tried to use the custom keyboard class on an editText in another activity and it works just fine. Am I missing something here? I'm confused as to why the custom keyboard does not show up properly.
Any help is very much appreciated, thank you.

Got it, I placed the keyboard layout in the search_result_inflate.xml like so:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/search_result_inflate"

<!-- a lot of components here -->

CardView has lost margin when inflating

In my activity, I am setting the layout activity_main onCreate. I am then wanting to inflate my CardView for each of the items in my array.
So far, I've got everything loaded, however my CardView's have lost their margin. When added to the layout through XML, the margin works, but when its inflated as a separate XML file the margin is lost.
I am inflating the activity_main_card like so:
LinearLayout item = (LinearLayout)findViewById(R.id.card_holder);
View child = getLayoutInflater().inflate(R.layout.activity_main_card, null);
item.addView(child);
In the activity_main_card, my XML is as follows:
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="#+id/card_view"
android:layout_gravity="center"
android:layout_width="match_parent"
android:layout_height="wrap_content"
card_view:cardCornerRadius="2dp"
android:layout_marginBottom="16dp">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:scaleType="fitCenter"
android:background="#drawable/cin"/>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="16dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="20sp"
android:textStyle="bold"
android:textColor="#color/dark_grey"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="12sp"
android:textStyle="normal"
android:textColor="#color/grey_500"/>
</LinearLayout>
</LinearLayout>
</android.support.v7.widget.CardView>
Can anyone point me in the direction where I am going wrong?

You're passing in null as the parent ViewGroup parameter to inflate(). This will cause all layout_* attributes to be ignored, as the inflater has no idea which attributes are valid for the container in which it will be placed (i.e. it has no idea which LayoutParams type to set on the View).
View child = getLayoutInflater().inflate(R.layout.activity_main_card, null);
should be
View child = getLayoutInflater().inflate(R.layout.activity_main_card, item, false);
For more info, see this great article about it -- it's a common mistake.

Android: ScrollView does not re-size when adding child views

I have a ScrollView that I am trying to populate dynamically. Here is the XML that contains the ScrollView:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#f6f5f5" >
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#40ff0000"
android:paddingBottom="70dp"
android:paddingTop="20dp"
android:paddingLeft="20dp"
android:paddingRight="20dp">
<LinearLayout
android:id="#+id/option_list_container"
android:background="#40ffff00"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/textView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="20dp"
android:background="#292929"
android:paddingBottom="5dp"
android:paddingLeft="15dp"
android:paddingTop="5dp"
android:text="Stap 3/5"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#color/white" />
</LinearLayout>
</ScrollView>
And here is the XML for the element I'm inserting in the ScrollvVew:
<?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:orientation="horizontal" >
<np.custom.FontIcon
android:id="#+id/option_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/calendar_circleround"
android:textSize="40sp"
android:gravity="center"
android:text="#string/planit_selection_empty_circle"
android:textColor="#292929" />
<TextView
android:id="#+id/option_text"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_vertical"
android:layout_marginLeft="10dp"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
This is the code I use to populate the scrollview:
ArrayList<String> g = new ArrayList<String>();
g.add("Fix a Bug");
g.add("Buy a new PC");
g.add("Make Coffee");
g.add("Take a Break");
g.add("Don't do that");
g.add("Throw your hands in the air like you just don't care!");
LinearLayout optionListLayout = (LinearLayout) rootView.findViewById(R.id.option_list_container);
LayoutInflater inflater = LayoutInflater.from(getActivity());
for(String p:g){
View v = inflater.inflate(R.layout.planit_option_item, null);
TextView optText = (TextView) v.findViewById(R.id.option_text);
optText.setText(p);
optionListLayout.addView(v);
}
This all works almost fine, except that the sizes of the ScrollView and the LinearLayout it contains do not come out as I expected. This a screenshot of that it looks like on a device, which shows text being cut out when it goes to a second line:
So how can I make sure the linear layout re-sizes to accommodate children views of different heights?

Your issue isn't the ScrollView not accommodating new children. The problem is that the text, when it spans more than one line, is being clipped due to layout parameters in R.layout.planit_option_item. Try changing the TextView of ID #+id/option_text so that its height is wrap_content.

Change your TextView for the ScrollView element to accommodate two lines:
...
<TextView
android:id="#+id/option_text"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_vertical"
android:layout_marginLeft="10dp"
android:maxLines="2"
android:singleLine="false"
android:textAppearance="?android:attr/textAppearanceMedium" />
...
This is not an issue with ScrollView, it's an issue with the specifications of the element you are inserting into the ScrollView. If you expect there may be more than 2 lines of text in some cases set maxLines = X where X is the maximum number of lines you expect.
Please let me know if this does not work and I would be happy to help further.

Horizontal Scroll View One Child(Eclipse IDE, Android)

I realize there many related problems, but I'm looking for this specific answer. The below code is my XML for my mainactivity in an app. Now my question. I would like to be able to alter the contents of the horizontal view, dynamically. This will involve clearing it of Views as well as adding new ones. How exactly do I go about doing this, as well as accessing the Linear Layout within it, when I tried to assign an ID to the Linear Layout I was given an error saying it could not accept a id of type string.
<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:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<TextView
android:id="#+id/txtClassification"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="Classification:<>"
android:textAppearance="?android:attr/textAppearanceLarge"
tools:ignore="HardcodedText" />
<Spinner
android:id="#+id/spinGoto"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_marginBottom="56dp" />
<Button
android:id="#+id/btnBack"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:text="Go Back"
tools:ignore="HardcodedText" />
<Button
android:id="#+id/btnSelect"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:text="Select"
tools:ignore="HardcodedText" />
<HorizontalScrollView
android:id="#+id/gallery"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/txtClassification"
android:layout_alignRight="#+id/spinGoto"
android:layout_below="#+id/txtClassification" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
</LinearLayout>
</HorizontalScrollView>
<ImageView
android:id="#+id/myImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</RelativeLayout>
All help is greatly appreciated!

You will have to work with the LinearLayout because a HorizontalScrollView can only have one direct child.
<HorizontalScrollView
android:id="#+id/gallery"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/txtClassification" >
<LinearLayout
android:id="#+id/yourLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
</LinearLayout>
</HorizontalScrollView>
Then you access it programmatically to add or remove views
public void addView(View v) {
LinearLayout yourLayout = (LinearLayout) findViewById(R.id.yourLayout);
yourLayout.addView(v);
}
public void clearLayout() {
LinearLayout yourLayout = (LinearLayout) findViewById(R.id.yourLayout);
yourLayout.removeAllViews();
}
public void removeView(View v) {
LinearLayout yourLayout = (LinearLayout) findViewById(R.id.yourLayout);
yourLayout.removeView(v);
}
hope this helps

The id has a predifined format. Enter the name you want after the "#+id/" syntax. Example android:id="#+id/layout".
Then in code get the LinearLayoutinside of the HorizontalScrollView:
LinearLayout layout = findViewById(R.id.layout);
To add a View to layout call the adView() of your layout. Example:
//add 5 buttons
for (int i = 1; i <= 5 ; i++){
Button btn = new Button(this);
btn.setId(i);
btn.setText(i+"");
layout.addView(btn);
}
To remove a View from the layout call removeView()
//remove button nr. 3
Button btn3 = layout.findViewById(3);
layout.removeView(btn3);
The HorizontalScrollView takes care of everything, you just have to populate and organize the elements inside the nested LinearLayout.
Good luck!
