cant move the text near each other

Hello i having some problem design the app I working on
I'm trying to make the TextEdit and The TextView be near each other but they still at the same place
i'm using a grid layout because I want the app be available for all sizes of all the devices
i'm kind of a beginner so I don't understand so much on developing android apps

how it looks like
the red arrows represent where I want the EditText to be (at the end of each Text View)

You have to bring "info" and "WelcomeText" and "nextBtn" out of "GridLayout", then add LinearLayout:

ImageButtons overlap in GridLayout, but don't want this

I am having problems with a GridLayout. In the layout below, phone_image and voip_image overlap and I don't want them to. phone_image is in column 0 and voip_image is in column 2.

Edit:
I tried using Space like so:
<android.support.v4.widget.Space
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:layout_column="1"
android:layout_row="5"/>
It seems to insert about 1/2 column, whereas using the blank image inserts a whole column. There may be parameters to play within the Space component though.

You can try to give android:maxWidth property to both voipImage and phoneImage ImageButtons, like this:
<ImageButton
android:id="#+id/phone_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_column="0"
android:layout_row="5"
android:maxWidth="96dp"
android:background="#null"
android:src="#drawable/ic_phone_enabled" />
<ImageButton
android:id="#+id/voip_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_column="2"
android:layout_row="5"
android:maxWidth="96dp"
android:background="#null"
android:src="#drawable/ic_voip_enabled" />
Update
The above changes are not necessary. I think that to solve your problem you can simply change the layout_column property of voip_image like this:
android:layout_column="1"
Hope this can help

One solution is to create a blank image and put it in the drawable folder.
Then use it to take up space in the layout like so:
<ImageButton
android:id="#+id/phone_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_column="0"
android:layout_row="5"
android:background="#null"
android:src="#drawable/ic_phone_enabled" />
<ImageButton
android:id="#+id/blank_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_column="1"
android:layout_row="5"
android:background="#null"
android:src="#drawable/ic_blank" />
<ImageButton
android:id="#+id/voip_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_column="2"
android:layout_row="5"
android:background="#null"
android:src="#drawable/ic_voip_enabled" />

Why does the length of a textview determine the position of other elements in android?

I have the following xml file to define my layout for an activity in android:
<GridLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:useDefaultMargins="true"
android:alignmentMode="alignBounds"
android:columnOrderPreserved="false"
android:columnCount="10"
android:background="#cccccc"
>
<TextView
android:text="#string/new_title"
android:textSize="32dip"
android:layout_columnSpan="10"
android:layout_gravity="center_horizontal"
android:id="#+id/textTitleEdit"
android:layout_row="0"
android:layout_column="0" />
<TextView
android:text="#string/new_descr"
android:textSize="16dip"
android:layout_columnSpan="8"
android:layout_gravity="left"
android:id="#+id/textSubTitleEdit"
android:layout_row="1"
android:layout_column="0" />
<TextView
android:text="#string/new_name"
android:layout_gravity="right"
android:layout_row="2"
android:layout_column="0"
/>
<EditText
android:ems="7"
android:singleLine="true"
android:inputType="textCapWords"
android:id="#+id/new_name"
android:layout_row="2"
android:layout_column="1" />

android:src="#mipmap/ic_backspace_black_24dp"
android:id="#+id/clear_line"
android:layout_row="2"
android:minHeight="15dp"

android:maxWidth="15dp"

android:id="#+id/new_search"
android:layout_row="2"

android:maxWidth="15dp"

android:layout_width="150dp"
android:max="10"
android:id="#+id/seek_offset"
android:layout_column="1"

<Space

android:layout_column="8"

</GridLayout>
This works fine, and I see something like in the following image (although I might have defined nonesense in this xml, or something incorrect, as I am a beginning beginner in Android...)
However, I am reusing this layout in some other activity and replace the text of the textView with the id textSubTitleEdit by a shorter text. As a consequence, the Ok-Button is shifted to the left, and is no longer at its place in the lower right corner.
Is there something wrong with my layout? How can the length of a TextView affect the position of a button?

The problem here is that you are using a GridLayout to place all your views in the layout.
If you want your buttons to stick to the bottom, one on each side of the screen, you may consider adding a RelativeLayout above your GridLayout, and move your button there as follows:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#cccccc"
>
<GridLayout
android:id="#+id/grid"
android:layout_margin="8dp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_above="#+id/new_cancel"
android:alignmentMode="alignBounds"
android:columnCount="10"
android:columnOrderPreserved="false"
android:useDefaultMargins="true">
<TextView
android:id="#+id/textTitleEdit"
android:layout_column="0"
android:layout_columnSpan="10"
android:layout_gravity="center_horizontal"
android:layout_row="0"
android:text="#string/new_title"
android:textSize="32dip"/>
....
<SeekBar
android:id="#+id/seek_offset"
style="#android:style/Widget.Holo.SeekBar"
android:layout_width="150dp"
android:layout_column="1"
android:layout_row="7"
android:max="10"/>
<Space
android:layout_column="0"
android:layout_columnSpan="3"
android:layout_gravity="fill"
android:layout_row="4"
/>
</GridLayout>
<Button
android:id="#+id/new_cancel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentStart="true"
android:background="#color/colorPrimaryDark"
android:text="Cancel"
/>
<Button
android:id="#+id/new_ok"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true"
android:background="#color/colorPrimaryLight"
android:text="Ok"
/>
</RelativeLayout>

Grid layout has space on last column

I have set up a grid layout with 6 columns and there is a space between column 5 and 6. The grid contains image buttons all with the same size. I have tried to use fill_parent and wrap_content but the gap still shows. I have also tried layout gravity=1 without results.
button image dimensions 104 x 104 pixels

parameters on all textviews are the same. all 15colums and 12 rows are used. hope you can help me

the solution is :
in your layout , you should declare :
<?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:orientation="vertical" >
<GridView
android:id="#+id/fragment_dandan_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:numColumns="3"
android:paddingTop="10dp"
android:listSelector="#0099f1"
android:divider="#drawable/parand_line_divider"
android:dividerHeight="1dp"
android:footerDividersEnabled="false"
android:headerDividersEnabled="false" />
</RelativeLayout>
