Can't edit EditText

I'm having a weird problem i've never encountered.
I'm building quite a complex layout for an activity. My only issue is, i can't edit the edittexts in any way. I've tried both with the emulator and the real device. To be more specific, when i click on the edittext, the cursor appears for a very short moment, then disappears. The keyboard never shows up. In the java code i didn't do anything with the EditTexts (not even called them yet).
Any idea what could be the issue?
I've already tried many solutions from other posts, with no luck.
Attaching the xml code here:

Remove android:descendantFocusability="blocksDescendants" from your LinearLayout it will work
"blocksDescendants"
The ViewGroup will block its descendants from | receiving focus.
Try this

Unable to align text to right of imageview android layout xml

I am trying to create layout like below in android:
But my problem is I am unable to add textbelow the image or on the right hand side of imageview. If I wrap ImageView and textview in a LinearLayout the then the whole view shrinks. Should I be using TableLayout?
My current layout xml is like below:

Hope this will help you and you will find your solutions from this xml code. I just modify some of your code
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Have placeholder views where text is not required.

How to set the max height of a list view

I have 3 vertical parts on the screen:
Some texts
Listview
Some more text fields
I don't understand why when there are more elements in the listview, it takes the whole screen to the bottom without leaving place for the 3rd part and makes this 3rd part unreachable and not visible.

I am sure you can find a solution only using the constraint layout and removing your linear layouts altogether but I don't know enough about ConstraintLayout to help you there. However you can give weights to the elements inside your Outermost LinearLayout. e.g. assign android:weightSum="3" to your outermost LinearLayout and then android:layout_weight="1" to the inner elements (in your case the other LinearLayouts)

Android, layout_above not working

I want to display some text in the middle of the screen, below header and above footer. Since this text is very long I nested it in ScrollView. I have tried a number of solutions: this, this, this, this, and a bunch more...
At first I had a problem of the two relative_layouts overlapping and text being cut of. The most accepted answer is to use layout_above and layout_below, but when I use layout_above, the text is never displayed.
This is what my xml looks like:

In you layout using two properties that why it doesn't work. So you can remove one properties here is your working code
<RelativeLayout
android:id="#+id/scrollViewAndStuff"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/linear_layout_header">
<ScrollView
android:id="#+id/scrollView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_marginTop="10dp">
<TextView
android:textColor="#000"
android:id="#+id/meetupDescription"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="5dp"
android:text="#string/text" />-
</ScrollView>
</RelativeLayout>
you can use this android:layout_below="#+id/linear_layout_header or this android:layout_above="#+id/ln_layout_footer, one property at a time. or simply copy and past

alignParentBottom working in emulator but not on device

I have a RelativeLayout with a LinearLayout inside it which should stick to the bottom of the screen. I have added the android:layout_alignParentBottom="true" property to it, and this works fine in the emulator, but on a real device this LinearLayout falls partially outside of the screen (I can only see the ImageViews but not the TextViews).

That is because of the scrolling behaviour, in that case, the last items of whatever will be scrolling are out of the screen actually. I guess what you could do is add a marginBottom to the root linearlayout?

Try this one
