Expand ListView not working while adding button

I tried Expand ListView method from using the code from the following blog, https://wirasetiawan29.wordpress.com/2016/01/20/membuat-expand-listview-material-design-di-android/
Everything works fine. But if I add a button in FrameLayout then the touchevent for listview item not works properly. Also I tried changing FrameLayout to Relative & also to Linear, but still no success.
<FrameLayout
android:id="#+id/wrapper"
android:layout_below="#+id/rl_title_wrapper"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.AppCompatTextView
android:id="#+id/deskripsi"
android:padding="16dp"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:text="Share"/>
</FrameLayout>
Thanks in advance.

According to Frame Layout description by Google's documentation...
FrameLayout is designed to block out an area on the screen to display
a single item. Generally, FrameLayout should be used to hold a single
child view, because it can be difficult to organize child views in a
way that's scalable to different screen sizes without the children
overlapping each other. You can, however, add multiple children to a
FrameLayout and control their position within the FrameLayout by
assigning gravity to each child, using the android:layout_gravity
attribute.
Hence, your original TextView is actually overlapping by the Button (Share). You can use android:layout_gravity="right" to position the button in the right end of the screen, however, then you will have to fix the maxium length of string for TextView, so that it doesn't get overlap by the Button on the right.
If you don't have any problem, might I suggest you to use LinearLayout? It's easier to handle and render by the GPU (As far as I know). Here's an example code of your item...
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/wrapper"
android:layout_below="#+id/rl_title_wrapper"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<TextView
android:id="#+id/deskripsi"
android:padding="16dp"
android:layout_weight="1"
android:layout_gravity="left|center"
android:text="This is a big chunk of description for your listView item. you can write as much as you want...."
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Share"
android:layout_gravity="right|center"/>
</LinearLayout>
You can also use RelativeLayout and GridLayout here.
I hope it answers your question. Cheers!

Why my TextView under an ImageView is not showing

I am writing an Android game. In the level selection activity's layout file, I want to layout the levels' buttons (They are actually ImageViews) like this:
x x x
x x x
And each level button has a TextView, with that level's name as the text, below it (Let's call these two views together as a "level choice"). I used a lot of LinearLayouts to do this. Here is the code for a level choice:
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center_horizontal"
android:layout_weight="1">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/angles"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/angles_level"
android:textSize="#dimen/level_text_size"/>
</LinearLayout>
As you can see, the two views' height and width are all wrap_content. But when I look at the designer, the text view doesn't show up.When I select the text view in the component tree, it shows where the text view is:
P.S. The picture isn't showing all six levels because I haven't made them yet.
As you can see, the text view is right at the bottom! When I select the ImageView, it shows that it is occupying all the space of its parent!
I don't know why this is happening, my image is certainly a square! Can you explain why this is happening and how do I fix it?
If you need my whole layout code, feel free to tell me in the comments.

For me, the best solution is to position and size it properly by code (where you have total control) instead of xml.
Anyway, i think your problem can be solved by setting ImageViews ScaleType
imageView1.setScaleType(ScaleType.FIT_START);
By XML:
android:scaleType="fit_start"
Hope this helps.

I use background color for textview when I'm studying the layout.
If you use wrap content in both dimension for TextView, that is invisible since you did not write any text inside it. wrap content means that the view take the minimum space. And no text means 0px; try to set ImageView and TextView with layout_weight 1 and layout_height 0dp. In this way both view take half of space of parent layout

Because right now, your LinearLayout doesn't know how to distribute the ratio of its children. And in fact, your imageview's wrap content already
consumes the whole space.
So, LinearLayout says "Sorry TextView, you have no space left".
Use layout_weight to both of the children.
I guess you want to have your picture twice the size of your text.
2:1
That is,
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center_horizontal"
android:layout_weight="1">
<ImageView
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight=2
android:src="#drawable/angles"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight=1
android:text="#string/angles_level"
android:textSize="#dimen/level_text_size"/>
</LinearLayout>

I just realized that I posted a question about ImageViews leaving out too much whitespace:
LinearLayout leaving out too much white space. Why?
I think this is the same as that problem. So I tried setting adjustViewBounds to true in the xml. And it works! Now the image view look like this:
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:src="#drawable/parallel_lines"/>

You can use relative layout
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/angles"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/angles_level"
android:textSize="#dimen/level_text_size"/>
</RelativeLayout>
or simple you can set background of textview to that image by putting this
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/angles_level"
android:background="#drawable/angles"
android:textSize="#dimen/level_text_size"/>

How to vertically align text in a TextView with Compound Drawable

This question is in a way a continuation of my last question.
My problem now is pretty much the same, except that instead of separating the image and text in differend views (namely ImageView and TextView) I learned I can use the attribute android:drawableLeft to set an image "for" my text (the suggestion was pointed to me by Eclipse with a warning icon on the LinearLayout line).
I thought the only difference would be that instead of setting the ImageView with setImageResource() method I would simply set the TextView's drawableLeft attributed with the setCompoundDrawablesWithIntrinsicBounds() method. Instead, when I made the change, I was taken back to my original issue: the text aligns with the top edge of the view rather than the center.
This is what my TextView looks like:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<TextView
android:id="#+id/account_login"
android:layout_marginTop="10dp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:drawableLeft="#drawable/pm_gmail"
android:drawablePadding="8dp"
android:text="example#gmail.com"
android:paddingLeft="16dp"
android:layout_gravity="left|center_vertical" />
<View
android:layout_width="fill_parent"
android:layout_height="1dip"
android:layout_centerVertical="true"
android:layout_below="#id/account_login"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:layout_marginTop="5dp"
android:background="#DDDDDD" />
</RelativeLayout>
The second View is just a separator.
... and this is what the layout looks like after setting the above mentioned attributes:
(I don't have enough reputation to post images yet, so here's the link to it)
(Just to be clear, this is only a static example. My text and image are both set dynamically in the code at runtime).
Any help is greatly appreciated.

Change android:layout_gravity="left|center_vertical" to android:gravity="center_vertical".
layout_gravity is for positioning a View inside a container (layout), while gravity is referred to
the View contents (that is, in this case, the text inside the TextView).

android layout with selector as a background, and overlapping text view

I want to draw a button using a "drawable/selector" so that the background color changes as the button is clicked.
So I defined the background of my RelativeLayout using the drawable (that has the selector). This first step works fine: when i click the layout object, the color changes.
In that RelativeLayout, I now add two independant dynamic Text Views. These Text Views are now using much of the space of the RelativeLayout. So when I click on the text views object, the background of the parent layout does not change anymore.
So, is there a way to have a layout with a dynamic background (to handle user's clicks so it changes color) and have overlapping views on the top?
Note that the background of the relativeLayout is a gradient that goes from top to bottom.
<RelativeLayout
android:id="#+id/titleBackground"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#drawable/button_background"
android:gravity="left|center_vertical"
android:clickable="true"
>
<TextView android:id="#+id/title"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="#color/light_text"
android:gravity="left|center_vertical"
android:singleLine="true"
android:ellipsize="end"
/>
<TextView android:id="#+id/subtitle"
android:layout_below="#id/title"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="#color/light_text_alpha"
android:gravity="left|center_vertical"
android:textSize="#dimen/secondarylisttext_size"
android:scrollHorizontally="true"
android:singleLine="true"
android:ellipsize="end"
/>
</RelativeLayout>

Your textview are capturing the click events and they are not passed to the relativelayout in the background. You will need to add a onTouchListener to both textviews and set the background for the relative layout inside the touch listener based on 'ACTION_DOWN,ACTION_UP' of the motion event.
There might be ways to make the textview pass the click events. But Im not sure about it. The above method is just 1 solution. There can be others.

As blessenm said, everything depends on the TextView, if you make them clickable then the parent selector doesn't count anymore (of course you can use a selector also on the TextView).

How to get UI to look right

I am having a problem getting the ListView to display properly. It currently looks like this with the following xml code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/favs_main">
<Button
android:text="Return to Home"
android:id="#+id/return_button"
android:layout_width="150dp"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
android:textSize="15sp"/>
<ListView
android:id="#+id/favsListView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="180dp"
android:layout_above="#id/return_button"/>
</RelativeLayout>
If you notice the list is down on the screen. I want it to be just below the favorites text instead of just above the return to home button. The catch however is that I always want the button to show and the list view to just occupy the space between the favorites text and the button. The text is from the background image so I can't just align below that. So even with 100 items I would still like to show the button.
Thanks for the help

If the word "favorites" is part of a background image as suggested in the RelativeLayout's background attribute, then you won't be able to align an element below it without using hacky margins or something to that effect. If you want to align an element below the word, separate that into a different ImageView and set the layout_below of the ListView to the id of that ImageView. To get an element to align properly in between two other elements, use a combination of layout_above and layout_below.

Couldn't you just align the ListView to the Parents' Top and set a margin for the ListView so that it is below the Text of the Background?
Also you could change the background to provide the Text in an ImageView and align the ListView to be below the ImageView.

Instead of trying to make a persistent View always show up under the ListView and align it (which you can do, see other suggestions), you might want to take a look at using a footerView:
http://developer.android.com/intl/de/reference/android/widget/ListView.html#addFooterView
"Add a fixed view to appear at the bottom of the list."
Note that it can be another layout too if you eventually need to do more than just one Button.

this my listview which have multiple entries and textview and button fixed in the botton. i haven't inserted background. try this hope it will help.

You could use a simple LinearLayout and use the weight attribute on the ListView :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:background="#drawable/favs_main">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<ListView
android:id="#+id/favsListView"
android:layout_width="wrap_content"
android:layout_weight="1"
android:layout_height="wrap_content"
android:layout_marginTop="180dp"/>
<Button
android:text="Return to Home"
android:id="#+id/return_button"
android:layout_width="150dp"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:layout_centerHorizontal="true"
android:textSize="15sp"/>
</LinearLayout>
