Android: height of LinearLayout didn't fill parent of ListView item

I have a ListView, the item is a RelativeLayout, at left is text, and the right side is ImageView in a LinearLayout.
I expect the height of the LinearLayout**(white background)** to be fillParent but it didn't.
The effect is :
Anyone can help on this?

I believe this is something that the parent RelativeLayout can't handle by itself - it creates kind of a vicious circle - parent defers the height to the child (wrap_content on the RelativeLayout) and the child defers the height to the parent (match_parent on main_list_item_delete_layout).
What you can do is to anchor the top of the main_list_item_delete_layout to the parent and its bottom to another view that is guaranteed to be the bottom (the LinearLayout on the left, containing the three text views):
<RelativeLayout ...>
<LinearLayout
android:id="#+id/left_layout"
android:layout_toLeftOf="#+id/main_list_item_delete_layout"
android:layout_toStartOf="#+id/main_list_item_delete_layout"
...
>
</LinearLayout>
<LinearLayout
android:id="#+id/main_list_item_delete_layout"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_alignParentTop="true"
android:layout_alignBottom="#id/left_layout"
...>
</LinearLayout>
</RelativeLayout>
PS: in your example, in case the text on the left LinearLayout is too long, it will overflow and overlap the delete layout - hence the addition of the anchor I added to the left layout.
PS2: I know this solution is very customized to your layout. If you are set on using the RelativeLayout as a parent, you might want to try the new ConstraintLayout.

Button doesn't appear in android appwidget layout

I have this xml file as a layout of an appwidget:
<?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="vertical"
android:background="#android:color/black" >
<!-- ListView to be shown on widget -->
<ListView
android:id="#+id/listViewWidget"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<Button
android:id="#+id/refresh_appwidget"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="refresh"
/>
</LinearLayout>
The button is not displayed, and I don't know the cause. I tested layout_with match_parent but always the same result.
How can I fix this issue?

Set a fixed height for the listview for example android:layout_height="400dp" in LinearLayout.
Or use a RelativeLayout
Or add your button as a footer to listview. So you can see the button when you scroll down
Or add your button as a header to listview.
With Relative layout you can place the button at the top or button and relative tot eh button you can place your listview.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:background="#android:color/black"
android:layout_height="fill_parent" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:text="Button" />
<ListView
android:id="#+id/listView1"
android:layout_above="#+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" >
</ListView>
</RelativeLayout>

Try with RelativeLayout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#android:color/black" >
<!-- ListView to be shown on widget -->
<ListView
android:id="#+id/listViewWidget"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<Button
android:id="#+id/refresh_appwidget"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="refresh"
/>
</RelativeLayout>
I try and see the Button but dont see the List

How to make a edittext view fill the parent element in android

I have two edittext views. One of them has only one line, its the title. But the other one should fill the linearlayout to the end, but it doesn't.
I updated the code so this is my whole xml for this app. I hope someone can find what's wrong. The part that i want to form like this is the part inside the LinearLayout named addView.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mainLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#ffffff">
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<Button
android:id="#+id/addButton"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:background="#drawable/addbuttonstyle"
android:layout_weight="20"/>
<ImageView
android:id="#+id/titleView"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:background="#drawable/titleview"
android:layout_weight="60"/>
<Button
android:id="#+id/orderButton"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:background="#drawable/orderbuttonstyle"
android:layout_weight="20"/>
</LinearLayout>
<FrameLayout

android:layout_width="fill_parent"
android:layout_height="wrap_content"

<LinearLayout

android:id="#+id/addView"
android:orientation="vertical"
android:layout_width="fill_parent"

<EditText
android:id="#+id/textBoxTitle"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="note title"
android:singleLine="true"
/>
<EditText
android:id="#+id/textBoxContent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:hint="content"
/>
</LinearLayout>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/backgroundLayout"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/background"
/>
</FrameLayout>

I changed textBoxTitle's height to wrap_content and I see this:
Is this what you were hoping for? Also if you want content to appear in the upper-left corner use this attribute:
<EditText
...
android:gravity="top"
/>

So i found what was wrong.
I needed to set layout_height (of the textBoxContent view) to 0dp and layout_weight (of the textBoxContent view) to 1.

The first view should have android:layout_width="wrap_content"

How to divide screen with three different-sized panel in android?

</LinearLayout>
</LinearLayout>

A RelativeLayout will accomplish what you want
<?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">
<LinearLayout
android:id="#+id/rightLayout"
android:layout_width="100dip"
android:layout_height="fill_parent"
android:layout_alignParentRight="true"
android:background="#003300"
android:orientation="vertical" >
</LinearLayout>
<LinearLayout
android:id="#+id/topLayout"
android:layout_toLeftOf="#id/rightLayout"
android:layout_width="fill_parent"
android:layout_height="100dip"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:background="#330033"
android:orientation="vertical" >
</LinearLayout>
<LinearLayout
android:id="#+id/bottomLayout"
android:layout_toLeftOf="#id/rightLayout"
android:layout_below="#id/topLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentLeft="true"
android:background="#334433"
android:orientation="vertical" >
</LinearLayout>
</RelativeLayout>
The result as LinearLayouts and as Buttons/TextViews (since I wasn't sure which you wanted):
If you are using the LinearLayouts as a container to hold multiple views then leave it as I have it.
If you plan on having only one view in each of your "parts" change the LinearLayouts in my layout file to that type.
Ex. if you want Part 1 to be just a button change
<LinearLayout
android:id="#+id/topLayout"
to be
<Button
android:id="#+id/topLayout"
Nested views are bad so its good to avoid them if you can

you could :
Main linear layout with vertical alignment
add a new linear layout with horizontal alignment
add a new linear layout with horizontal or vertical alignment
So in the first layout ( the left part of main layout) you add a new linear layout with horizontal alignment and add the two elements you want.
In the second layout ( the right part of main layout) you add a new linear layout or directly the object you want to show

Fitting image layout

Attached image shows an interface. Notice the black part on the bottom. How do I pull my footer image to the bottom? I used fill_parent on my middle layout but it fills the whole screen and the footer wont show.

You can use weight attribute.
for example see the headerfooter.xml in this answer you can make your xml like that.

Using fill_parent on middle layout make your middle layout take all screen height left.
You can have relative layout as main layout and set footer android:layout_alignParentBottom="true".

Easiest way is to use a RelativeLayout for your entire layout.
You can then set the footer attribute layout_alignParentBottom="true" which moves it to the bottom. You will also have to set the body to layout_above="#+id/idoffooter", so that it does not disappear behind the footer.
Another way would be to use a vertical LinearLayout where you give the body a weight of 1, but the RelativeLayout way is imho better.
