Android Linear Layout buttons not aligning after adding text to one of them

I am trying to put 6 buttons in the middle of the screen and it worked until I added text to one of them, as you can see in the picture below :
https://imgur.com/IxIVgHj
This is the code for the 2 buttons that causes problems :
<LinearLayout
android:id="#+id/tableRow3"
android:padding="5dp"
android:layout_gravity="center_horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:id="#+id/utilitiesButton"
android:layout_width="125dp"
android:layout_height="125dp"
android:layout_marginLeft="10dp"
android:background="#drawable/menu_sms"
android:gravity="bottom|right"
android:padding="10dp"
android:text="0"
android:textColor="#color/red"
android:textSize="40dp" />
<Button
android:id="#+id/statisticsButton"
android:layout_width="125dp"
android:layout_height="125dp"
android:layout_marginLeft="10dp"
android:background="#drawable/menu_statistics"
android:gravity="center_vertical|center_horizontal" />
</LinearLayout>
I need the text to be bottom|right. The bigger the text size from the left button is, right button goes down more. Any ideas on this ?
Thank you,
Marius

If you set android:baselineAligned="false" on the LinearLayout, then the buttons inside the LinearLayout would align properly.

Instead of using a LinearLayout try and use relative layout instead, with an android:gavity of fill_horizontal, and add a bit of space between your textviews, also try and decrease the padding on the first button.

Why view elements are going out of the page

I have a keyword search option with EditView and a button in my android app, which in ADT looks perfect.
But when i run the program, the EditView expand beyond the viewing area and search button disappears because it goes out of page.
Xml for this is:
<TableRow
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<LinearLayout
android:id="#+id/detail_ll"
style="#style/search_bg_style"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<EditText
android:id="#+id/keyword_detail"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.7"
android:ems="10"
android:hint="#string/keyword" />
<Button
android:id="#+id/button_search"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.3"
android:text="#string/search" />
</LinearLayout>
</TableRow>
Please help me in getting this in viewing area..

can you post the entire xml?
i mean with the
<TableLayout />
main tag
try setting android
android:layout_weight="1"
for both
or try android:layout_weight="1.5"
for edit text and
android:layout_weight="0.5"
for the button

I think you should make the android:layout_width="wrap_content" to android:layout_width="match_parent" or any fixed width (in dps) in the TableRow element.
layout_weight attribute divides a pre-known space according to its weight which is not present in this case.

Here you have to TableRow and LinearLayout height MatchParent and
give Weightsum="1" to LinearLayout it will fixed your problem and also remove android:ems property from Edittext
Hope this Help you.

Button size and padding within RelativeLayout

I'm attempting to create a a Heading + button similar to the Google Music App, e.g. where there is a "Songs" Header on the Left and then on the right there is a Button with the text "X more"..
I've using a RelativeLayout for the TextView and Button
My problem is that the button is taking up the size of the layout that contains the text the height is all wrong and the padding doesn't seem to do anything.
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
[REMOVED for clarity]
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/list_foreground"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:text="#string/photos"
android:textAppearance="?android:attr/textAppearanceMedium" />
<Button
android:id="#+id/photo_button"
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:background="#color/actionbar_background"
android:padding="10dp"
android:text="test" />
</RelativeLayout>
What am I doing wrong here?

RelativeLayouts are designed to have children in the layout "relative" to each other. In other words, if you want the Button to the right of the Textview, you need to tell it.
Because you are aligning relative to the parent LEFT / RIGHT, it appears that things are "kind of" working.
You may be better off with a LinearLayout, depending on your needs. LinearLayouts use "orientation" not RelativeLayouts.
You should look over some tutorials (like this one: http://mobile.tutsplus.com/tutorials/android/android-layout/) but ultimately you will probably put your button in first and then your text view so that the textview content will wrap appropriately.

To get the same effect as the Music App I ended up using a RelativeLayout but instead of a Button I'm using another TextView, this is giving the impression it's a button but it gives me more scope to format the background etc. I think just setup a OnClickListener in the code
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/photo_title">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="10dp"
android:text="#string/photos"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:id="#+id/more_photo_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="10dp"
android:background="#color/actionbar_background"
android:paddingLeft="5dp"
android:paddingRight="5dp"
android:text="10 MORE"
android:textColor="#color/button_text"
android:textSize="12sp" />
</RelativeLayout>

Dynamic TextViews wrapping to next row/line in Linear layout

I am trying to build a UI, where in I have a linear layout which has been defined in the XML.
As per the user's input, I need to add some TextViews to this linear layout. I am able to do this.
My actual problem is, when I have more text views, they are stacked next to each other and some of text views text are hidden or stretched vertically as shown in the image below.
I would like to use the whole width of the linear layout and if the text view can not fit in this row, it should be put in a new row or below the first text view.. I would like the display to be as below.
Following is my Linear layout configuration in XML:
<RelativeLayout
android:id="#+id/RL1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:paddingBottom="5dip"
android:paddingTop="5dip" >
<TextView
android:id="#+id/text1"
android:layout_width="85dip"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:gravity="left"
android:text="Lable 1"
android:textColor="#999999" />
<LinearLayout
android:id="#+id/LL1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toLeftOf="#+id/button1"
android:layout_toRightOf="#+id/text1"
android:gravity="left|center_vertical"
android:orientation="horizontal"
android:paddingLeft="5dip"
android:paddingRight="5dip"
android:paddingTop="3dip" >
</LinearLayout>
<Button
android:id="#+id/button1"
android:layout_width="30dip"
android:layout_height="30dip"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginTop="2dip"
android:background="#drawable/plus"
android:clickable="true"
android:focusable="true"
android:paddingTop="5dip" />
</RelativeLayout>
Can any one please help me in how to realign the same in java code.

I would Like to suggest you about how you can provide equal sizes to all your views in Linear Layout,you can do that by using weight property in the XML file i.e., android:weight for that particular View and when you use this property you should give width=0dp or 0dip.I think this will solve your problem easily.
Please I suggest you first you take full Knowledge of how to use this property in the following Link:-Weight property with an example

Please see:
How to wrap Image buttons in a horizontal linear layout?
How can I do something like a FlowLayout in Android?
You also might search github for FlowLayout.java.
An alternative approach is given in:
Android - multi-line linear layout
In addition, there's a class that adds images into a TextView:
https://stackoverflow.com/a/21250752/755804
which is not the same as wrapping views in the general case, but sometimes may do the job.

i'm korean.
so i don't speak English well, but i'll help you.
first, Create 'item.xml' with four text boxes.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/set_checkbox"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/text2"
android:text="0"
android:layout_weight="1"
android:gravity="center"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/text3"
android:text="0"
android:layout_weight="4"
android:gravity="center"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/text4"
android:text="0"
android:layout_weight="4"
android:gravity="center"/>
</LinearLayout>
second, Create 'main.xml' where 'item.xml' will be dynamically generated.
'orientation' helps to create one line at a time.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
</LinearLayout>
Finally, You can create four TextView per line using the code below.
LinearLayout layout = (LinearLayout)findViewById(R.id.mainxml);
LinearLayout item = (LinearLayout)layout.inflate(this.getContext(), R.layout.itemxml, null);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(MATCH_PARENT, WRAP_CONTENT);
item.setLayoutParams(params);
CheckBox cb = item.findViewById(R.id.set_checkbox);
TextView text2 = item.findViewById(R.id.text2);
TextView text3 = item.findViewById(R.id.text3);
TextView text4 = item.findViewById(R.id.text4);
cb.setChecked(true);
text2.setText("text2");
text3.setText("text3");
text4.setText("text3");
layout.addView(item);
The 10th loop is shown in the following picture.

Centering a TextView while keeping it to the right of a button?

I'm pretty sure I've done this before, but I've forgotten how.
Here's the problem:
I've got a button and a textview, and I want the textview to be centered, while the button is on the left side.
No problem? Just put them in a relativelayout, make the textview centerinparent, and the button alignparentleft.
But now I'm going to dynamically change the text, so it can potentially be written on top of the button! I'll just add toRightOf="#id/button" on the textview. No, now it's no longer centered.
I wish I could provide a screenshot, but it seems the computer is out of memory and can't do that.
Here's some code: http://pastebin.com/3N70Vjre (Since I can't paste xml...?)
<RelativeLayout
android:id="#+id/header"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true">
<Button
android:id="#+id/leftbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:text="text!"
/>
<TextView
android:id="#+id/toptext"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#android:color/white"
android:layout_toRightOf="#id/leftbutton"
android:layout_centerInParent="true"
android:textSize="16sp"
android:textStyle="bold"
android:text="Text!"
android:singleLine="true"
/>
</RelativeLayout>

Try this (unfortunately I'm at work so can't jump into Eclipse to get you some code) -
Change the layout_width of the TextView to fill_parent.
Set the gravity of the TextView to center (so the text centers inside the TextView)
Set the layout_weight of the Button to 1 and the layout_weight of the TextView to 2. Note that you may have to fudge with these numbers to get the layout you're looking for.
This should center the text of the TextView after the Button, though it will not center the TextView itself. You can accomplish that by replacing the TextView with a container (Linear/Relative Layout) and doing the same method as above on the Layout instead of the TextView. You would then put your TextView inside the container and set the container's gravity to "center".
Hope this helps point you in the right direction :)

You can try this (pseudo-code):
<RelativeLayout>
<Button>
<LinearLayout toLeftOf="toptext" type="horizontal">
<TextView gravity="center">
</LinearLayout>
</RelativeLayout>
You might have to have the LinearLayout as width="fill_parent". Not sure if that will work nor not. You can subsequently try some of the things listed here: http://thinkandroid.wordpress.com/2010/01/14/how-to-position-views-properly-in-layouts/

Try declaring the TextView first, then aligning the button to the left of the text view. Keep in mind you may run into issues if the TextView becomes too wide.
EDIT: I see, so you're trying to do something sort of like the iPhone's header with back/next buttons (similar anyway). Try this modification. I still believe you're going to run into issues if the TextView gets large enough to hit the Button, though.
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/header"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
>
<TextView
android:id="#+id/toptext"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#android:color/white"
android:layout_alignParentCenter="true"
android:textSize="16sp"
android:textStyle="bold"
android:text="Text!"
android:singleLine="true"
/>
<Button
android:id="#+id/leftbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="text!"
/>
</RelativeLayout>
Try this FrameLayout instead. This may do more what you're expecting:
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:id="#+id/toptext"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:textColor="#android:color/white"
android:textSize="16sp"
android:textStyle="bold"
android:text="Text!"
android:singleLine="true"
/>
<Button
android:id="#+id/leftbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Text!"
/>
</FrameLayout>
