Edittext does not show keyboard

for some reason, my edittext does not show the keyboard when tapped on, i have no idea what is wrong, any help would be greatly appreciated
i have tested this using an emulator and an actual device, but neither work
<?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">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Notification text:"
android:id="#+id/intro"/>
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/intro"
android:id="#+id/txt_tekstNotif"
android:textSize="20dp"
android:lines="4"
android:focusable="true"/>
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#id/txt_tekstNotif"
android:text="#string/cre_notif"
android:id="#+id/btn_cre_notif"/>
</LinearLayout>

You need to give a size to you EditText otherwise it's size is 0.
You set it as "wrap_content" and you have no content. So you either set a background drawable to it or put some text or "hint" in it so it will have an actual size.
Just try and put android:layout_width="50dp"
android:layout_height="100"
and see if it works.

Android AutoCompleteTextView suggestions overlapping the TextView

I am making an application using Google maps. I am using AutoCompleteTextView to get suggestions of places. The output is as follows :
As you can see from the image, the border of the suggestion box is overlapping the TextView. I am using custom item layout with a Textview inside a Linear Layout.
<?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="fill_parent"
android:background="#fff"
android:orientation="horizontal" >
<TextView
android:id="#+id/resultValue"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#fff"
android:paddingBottom="5dp"
android:paddingLeft="5dp"
android:paddingRight="5dp"
android:paddingTop="5dp"
android:textColor="#474040"
android:textSize="15sp" />
</LinearLayout>
Is there a way to bring the suggestion window down and to remove or change the colour of the grayish border of the suggestion window ?

Was doing the same thing as in the accepted answer, but was still having the overlap issue. To fix that make this call:
autocompleteView.setDropDownVerticalOffset(0);

Try like this, android:popupBackground="#EFEEEC"// change according your border you want for the suggestion box
<AutoCompleteTextView
android:id="#+id/autocomplete"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:background="#drawable/text_area"
android:inputType="text|textNoSuggestions|textMultiLine"
android:paddingLeft="10dp"
android:popupBackground="#EFEEEC"
android:textColor="#333333"
android:textColorHint="#9c9c9c"
android:textSize="18sp"
android:completionThreshold="1" />
and auto_textview.xml
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="12dp"
android:textColor="#333333"
android:layout_margin="15dp"
android:textSize="16sp" >
</TextView>

Final output will look like
Hope this help you.

Use a custom drawable like
AutoCompleteTextView txtNames= (AutoCompleteTextView)findViewById(R.id.editBox);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.drawable.customlist, restList);
txtRestNames.setAdapter(adapter);
and add customlist as
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/cust_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="5dip"
android:textSize="12dp"
android:singleLine="false"/>
Change the parameters/color to suit your needs. Try it....hope it helps

RelativeLayout textviews overlapping

I have a rather simple ListView row:
<?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="horizontal" >
<TextView
android:id="#+id/tournament_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:textSize="25dp" />
<TextView
android:id="#+id/tournament_winner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:textSize="25dp" />
</RelativeLayout>
When the text of "#+id/tournament_name"is long - it overlaps with the one from "#+id/tournament_winner" and I don't understand why.
I tried using android:singleLine="false"to no avail. I also tried using android:inputType="textMultiLine"as the docu says android:singleLine="false" is deprecated but then I get the warning: Attribute android:inputType should not be used with <TextView>: Change element type to
<EditText> ? so no good here as well.
I also tried using android:ellipsize="end" but this doesn't work. I assume it is because the text in the left TextView ("#+id/tournament_name") is NOT long enough to fill up the full width of the ListView (which code is not sowing here).
I was sure that if I use android:layout_width="wrap_content"the two TextView fields shouldn't overlap.
Here is an example (see the second line):
Any further ideas how this could be fixed?

android:layout_toLeftOf="#id/tournament_winner" in First TextView.
Also set android:maxLines="1" and Fix width for tournament winner because when it gets long tournament name cant see...
row.xml
<?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="horizontal" >
<TextView
android:id="#+id/tournament_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="#id/tournament_winner"
android:maxLines="1"
android:text="NAMEEEEEEEEEEEEEEEEEEEEEEEEEEE"
android:textSize="25dp" />
<TextView
android:id="#+id/tournament_winner"
android:layout_width="wrap_content" android:layout_marginLeft="10dp"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="WINER"
android:textSize="25dp" />
</RelativeLayout>

Thank you very much for your answer - sorry it took me some time to respond. I ended up using your android:layout_toLeftOf="#+id/tournament_winner" but left the single line and the margin to the left unused, as the result seemed perfect to me (hope this is also the case for other devices).
One thing though - in the first text view (tournament_name) I had to use android:layout_toLeftOf="#+id/tournament_winner"and not android:layout_toLeftOf="#id/tournament_winner" - pay attention to the added +. For some reason I get an error using android:layout_toLeftOf="#id/tournament_winner": Error: No resource found that matches the given name... so it seems that it is possible and NEEDED to define the resource in the time of calling it because the system doesn't know it before it was defined.
<?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="horizontal" >
<TextView
android:id="#+id/tournament_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="#+id/tournament_winner"
android:layout_alignParentLeft="true"
android:textSize="25dp" />
<TextView
android:id="#+id/tournament_winner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:textSize="25dp" />
</RelativeLayout>

You can use single text view in place of two and simply display both strings in one text view !!

Android View background layout problem

I am trying to use a empty View to indicate the color for each item in a ListView.
The idea is that the rowColor View is just a 3dp wide line that should automatically size to the height of secondLine and thirdLine (note that all of the content is set in code including the background color of rowColor and that firstLine and thirdLine are often set to GONE).
It shows up perfectly in Eclipse's Graphical Layout but the rowColor does not show up at all on my phone (running 2.3.3) and all the views are stacked. Any idea how to fix it?
The following code for the list_row was adopted from here. I've provided all the code that I would think works based on that layout, but not even close. Does that layout still work?
list_row.xml:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:padding="6dip">
<TextView
android:id="#+id/firstLine"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:singleLine="true"
android:text="First Line" />
<View
android:id="#+id/rowColor"
android:background="#FF0000"
android:layout_width="3dp"
android:layout_height="fill_parent"
android:layout_below="#id/firstLine"
android:layout_alignParentBottom="true" />
<TextView
android:id="#+id/thirdLine"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/rowColor"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:singleLine="true"
android:text="Third Line" />
<TextView
android:id="#+id/secondLine"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/rowColor"
android:layout_alignParentRight="true"
android:layout_below="#id/firstLine"
android:layout_above="#id/thirdLine"
android:layout_alignWithParentIfMissing="true"
android:gravity="center_vertical"
android:singleLine="true"
android:text="Second Line" />
</RelativeLayout>
main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView
android:id="#+id/android:list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>

Thanks.

I tested your layout in several emulators (from 2.1 to 2.3.3) and it works fine, with or without setting the first TextView visibility to View.GONE.
It must be either a problem in your code elsewhere or a glitch of your specific device.
As a workaround, you can use:
android:layout_height="0dp"
for your rowColor View. Since you are already defining the position of the top and bottom limits with android:layout_below="#id/firstLine" and android:layout_alignParentBottom="true", the actual value of layout_height is irrelevant.

I ran into this recently, and I found that a View with no content apart from a background color will not appear in a RelativeLayout.
If you can, try converting your layout to a LinearLayout. This seems to work for me.

Custom titlebar positioning

I've created a custom titlebar for my Android application. All is well except I've placed a checkbox on the titlebar and I want my checkbox to be positioned farther left (so I can line it up with the checkboxes in each list item). I can not figure out how to move it farther left. It's almost like that's as far as it will let me put it. Here is a screenshot of what I mean as well as my titlebar XML:
http://i28.tinypic.com/2dpfn9.png
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
style="?android:attr/windowTitleBackgroundStyle"
android:layout_height="?android:attr/windowTitleSize"
>
<CheckBox
android:id="#+id/inbox_selectall"
android:text=""
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="left|center_vertical"
android:focusable="false"
android:background="#drawable/checkbox_background"
android:button="#drawable/checkbox"
/>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerVertical="true">
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
style="?android:attr/windowTitleStyle"
android:id="#+id/inbox_title"
android:text="#string/title_inbox"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_vertical|center_horizontal"
android:background="#null"
android:fadingEdge="horizontal"
android:scrollHorizontally="true"
/>
</LinearLayout>
</RelativeLayout>

One thing to note is that when you set android:background to a 9-patch, you assume its padding. For the title bar graphic, there are a few pixels of left-padding (see the bottom row of pixels). I don't remember off the top of my head, but you may be able to override it using android:padding.
