How to create a paragraph in android studio?

I want to create a layout of the list item as shown in the image.I divided it into three parts taking whole layout as Linear(orientation-horizontal).Three parts are
1) Image
2) Paragraph
3) three edit text in a linear layout.
I have problem in the second part as the length of paragraph (Text View) it disturbs the next part.I also try by putting weight in relative layout but it does not work.What is the solution for this problem?
How to do something like this.
Code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/item_icon"
android:src="#drawable/hammer"
android:layout_weight="1"
android:layout_width="100dp"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/item_name"
android:layout_toRightOf="#id/item_icon"
android:layout_weight="1"
android:text="skvnksjdjbkjbkjb"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<LinearLayout
android:id="#+id/item_detail"
android:layout_toRightOf="#id/item_name"
android:layout_weight="1"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="#+id/detail1"
android:layout_weight="1"
android:text="fkvjbfvkjbv"
android:textSize="20dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/detail2"
android:layout_weight="1"
android:text="fkvjbfvkjbv"
android:textSize="20dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/detail3"
android:layout_weight="1"
android:text="fkvjbfvkjbv"
android:textSize="20dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</LinearLayout>

if you use layout_weight, the layout_width (for horizontal LinearLayouts) should be set to 0dp

FrameLayout in LinearLayout is pushed to side in View

I have a game layout in my app that has four buttons that should display at the top of my view and then I have two FrameLayouts that are also in this linear layout. The first FrameLayout just makes the top 1/4 of the view so my imageButtons that implement the Drag and drop API are not allowed at the top. The second FrameLayout is for the bottom 3/4 of the view which has 4 imagebuttons in it.
My issue is that when the game layout is displayed, the buttons in the linear layout are displayed just how i want them to, but the two FrameLayouts are squished to the top right corner.
Here is the code:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/game_layout" >
<Button
android:id="#+id/doneButton"
android:layout_width="170dp"
android:layout_height="wrap_content"
android:onClick="onDoneClicked"
android:text="#string/done" />
<Button
android:id="#+id/cancelButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="onCancelClicked"
android:text="#string/cancel" />
<Button
android:id="#+id/leaveButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="onLeaveClicked"
android:text="#string/leave" />
<Button
android:id="#+id/finishButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="onFinishClicked"
android:text="#string/finish" />
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="0.75"
android:orientation="horizontal"
android:id="#+id/topHalf" >
</FrameLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="0.25"
android:orientation="horizontal"
android:id="#+id/bottomHalf" >
<ImageButton
android:id="#+id/polarCapButton1"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="top|left"
android:background="#drawable/polarcap" />
<ImageButton
android:id="#+id/polarCapButton2"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="top|right"
android:background="#drawable/polarcap" />
</FrameLayout>
<TextView
android:id="#+id/scores"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ImageButton
android:id="#+id/spaceRockButton1"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|left"
android:background="#drawable/spacerock" />
<ImageButton
android:id="#+id/spaceRockButton2"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|right"
android:background="#drawable/spacerock" />
</LinearLayout>
Any help would be appreciated guys. Thanks.

I see several things that can be a potential problem.
Your linear layout contains several widgets and only 2 of those contain layout_weight values. To solve this issue, you want to wrap your two frame layouts in another LinerLayout container, where you specify the distribution of your 2 frame layouts inside your new linear layout.
In your new linerLayout, you want to specify the total weight of the layout, such as: android:weightSum="1".
Depending of your linear layout orientation, (if unspecified, it will be horizontal) If your LinearLayout orientation is horizontal, specify: android:layout_width="0dp". If the orientation is vertical, specify: android:layout_height="0dp" for the child elements.
Also, it seems to me that you want your buttons to align horizontally next to each other (horizontal orientation), and your two frames to align underneath the buttons, but right underneath each other (vertical orientation).
So in this case, the code would look something like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:id="#+id/top_layout" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:id="#+id/game_layout" >
<Button
android:id="#+id/cancelButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="onCancelClicked"
android:text="#string/cancel" />
<Button
android:id="#+id/leaveButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="onLeaveClicked"
android:text="#string/leave" />
<Button
android:id="#+id/finishButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="onFinishClicked"
android:text="#string/finish" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:weightSum="1"
android:id="#+id/ll_layout_frames" >
<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.75"
android:orientation="horizontal"
android:id="#+id/topHalf" >
</FrameLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.25"
android:orientation="horizontal"
android:id="#+id/bottomHalf" >
<ImageButton
android:id="#+id/polarCapButton1"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="top|left"
android:background="#drawable/polarcap" />
<ImageButton
android:id="#+id/polarCapButton2"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="top|right"
android:background="#drawable/polarcap" />
</FrameLayout>
</LinearLayout>
<!-- you can insert more widgets here, they will be placed in the vertical linear layout -->
</LinearLayout>

android child layout not showing

I have a LinearLayout with three RelativeLayout inside. The first two children layouts show. The third one does not show. When I change the children from RelativeLayout to LinearLayouts, the third one still does not show. Any ideas on how to fix this? The one not showing contains the ImageView.
Here is the code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="60dp"
android:clickable="true"
android:orientation="horizontal" >
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#drawable/back1" >
<View
android:id="#+id/fract"
android:layout_width="60dp"
android:layout_height="1dp"
android:layout_centerInParent="true"
android:background="#00a5e5"
android:paddingLeft="5dp"
android:paddingRight="5dp" />
<TextView
android:id="#+id/nume"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#id/fract"
android:layout_centerHorizontal="true"
android:ellipsize="end"
android:singleLine="true"
android:text="58 apple"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textSize="14sp" />
<TextView
android:id="#+id/denom"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/fract"
android:layout_centerHorizontal="true"
android:ellipsize="end"
android:singleLine="true"
android:text="46 orange"
android:textSize="12sp"
android:textStyle="bold" />
</RelativeLayout>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#drawable/back2" >
<TextView
android:id="#+id/red_1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:ellipsize="end"
android:singleLine="true"
android:text="11 apple "
android:textAppearance="?android:attr/textAppearanceMedium"
android:textSize="14sp" />
<TextView
android:id="#+id/red_2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/red_1"
android:layout_centerHorizontal="true"
android:layout_marginRight="5dp"
android:ellipsize="end"
android:singleLine="true"
android:text="13 oranges "
android:textSize="12sp"
android:textStyle="bold" />
</RelativeLayout>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#ffffff" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignParentRight="true"
android:src="#drawable/guess" />
</RelativeLayout>
</LinearLayout>

Your second Relative Layout's height is
android:layout_height="match_parent"
try putting:
android:layout_height="wrap_content"
--edit - try adding a weight attribute.
</RelativeLayout>
<RelativeLayout
android:weight=1
>
</RelativeLayout>
<RelativeLayout
android:weight=1>
</RelativeLayout>

android:layout_centerInParent="true" remove this from the view, if you want to add a view you can add separately out of the RelativeLayout with this your Layout is already in the center of the parent, For debug purpose set the width of each view to certain level so that you can see. Your two RelativeLayout already took the width of the Linear Layout, so no space left for the third Layout.

I decide to do it programmatically. I get the width of the device using context.getResources().getDisplayMetrics().widthPixels. Then from there I layout my pieces pixels by pixels, so to speak.

Custom dialog height to match content

This is my custom dialog, there are some textboxs and two buttons.
I'm using a RelativeLayout on it.
I'd like the dialog size to match the content, not all that blank space under there.
I don't want to use explicit pixel heights (it's not good practice).
Another thing, there's a way to have some space between every view?
This is my XML
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/txt_desc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="8pt"
android:textStyle="italic" />
<TextView
android:id="#+id/txt_date"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_below="#+id/txt_desc"
android:textSize="8pt" />
<TextView
android:id="#+id/txt_place"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_below="#+id/txt_date"
android:textSize="8pt" />
<Button
android:id="#+id/btn_close"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_below="#+id/txt_place"
android:layout_toRightOf="#+id/view"
android:text="#string/btn_close" />
<View
android:id="#+id/view"
android:layout_width="0dp"
android:layout_height="1dp"
android:layout_centerHorizontal="true" />
<Button
android:id="#+id/btn_edit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/txt_place"
android:layout_toLeftOf="#+id/view"
android:drawableLeft="#android:drawable/ic_menu_edit"
android:text="#string/btn_edit" />
</RelativeLayout>

First question
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
Second question
Plus use android:marginTop="5dp" if you want to separate a View from Top for 5 dp.
marginLeft|Right|Bottom are also available.
<TextView
android:id="#+id/txt_place"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginTop="5dp" <-----------------
android:layout_below="#+id/txt_date"
android:textSize="8pt" />
By the way, if I were you, I'd nest some layouts to make order. You can have a general Relative Layout, then 2 linear layouts: one horizontal for TextViews and one vertical for Buttons. You can definely play with your editor and try to make the best appearance for your dialog.
EDIT
Try this one:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#0000"
android:orientation="vertical"
android:paddingBottom="50dp" >
<LinearLayout
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/txt_desc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="prova"
android:textSize="8pt"
android:textStyle="italic" />
<TextView
android:id="#+id/txt_date"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:text="prova"
android:textSize="8pt" />
<TextView
android:id="#+id/txt_place"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:text="prova"
android:textSize="8pt" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<Button
android:id="#+id/btn_edit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableLeft="#android:drawable/ic_menu_edit"
android:text="btn_edit" />
<Button
android:id="#+id/btn_close"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="btn_close" />
<View
android:id="#+id/view"
android:layout_width="0dp"
android:layout_height="1dp" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
I've hard-coded the texts. The main idea is to use a big container layout in background, which is trasparent (background=#0000) and in top of that a layout in wrap_content containing your Views.
If this solution doesn't resolve your problem, I think you could edit height directly in your code. Try to relate to this question

Set your relative layout's height to wrap_content.
For example:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!-- More XML -->
</RelativeLayout>
Also be aware that fill_parent is deprecated for widths and heights.
You can add either margin (extra space outside a view) or padding (extra space inside a view) with android:layout_margin or android:padding respectively. There are also variants such as layout_marginTop that only apply to a specific side of the view.

Button on the left of a frame layout?

In a vertical linear layout, I have 2 textviews, then a button and then a frame layout.
I would like the button to be on the left of the frame layout. I tried putting the button in a relative layout, but how do I tell the frame layout to be on the right?
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/content_container_white"
android:orientation="vertical" >
<TextView
android:id="#+id/editText1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingLeft="30dp"
android:text="#string/t0"
android:textColor="#color/black"
android:textSize="30dp" />
<TextView
android:id="#+id/editText2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/t1"
android:textColor="#color/black" />
<RelativeLayout
android:id="#+id/RelativeLayout1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Button
android:id="#+id/buybtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:layout_marginLeft="30dp"
android:text="#string/buy_button" />
</RelativeLayout>
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal|right"
android:layout_marginTop="10dp" >
<ImageButton
android:id="#+id/videothumb"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal|center_vertical"
android:src="#drawable/button_play_on" />
<ImageView
android:id="#+id/videothumbimage"
android:layout_width="380dp"
android:layout_height="170dp"
android:scaleType="centerCrop"
android:src="#drawable/demo_thumb_home" />
</FrameLayout>
</LinearLayout>

You can do it by simply telling your FrameLayout android:layout_toRightOf="#+id/#+id/buybtn", but your FrameLayout must be inside a RelativeLayout too.
<RelativeLayout
android:id="#+id/RelativeLayout1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Button
android:id="#+id/buybtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:layout_marginLeft="30dp"
android:text="#string/buy_button" />
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal|right"
android:layout_marginTop="10dp"
android:layout_toRightOf="#+id/#+id/buybtn" >
<ImageButton
android:id="#+id/videothumb"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal|center_vertical"
android:src="#drawable/button_play_on" />
<ImageView
android:id="#+id/videothumbimage"
android:layout_width="380dp"
android:layout_height="170dp"
android:scaleType="centerCrop"
android:src="#drawable/demo_thumb_home" />
</FrameLayout>
</RelativeLayout>

Push FrameLayout into RelativeLayout or just put button and frame together in horizontal LinearLayout - what would be more simple
ps - kepp your code clean, use ctrl+shift+F (if using Eclipse) to auto-arrange it

Put your framelayout within Relativelayout and then set property align parent right.

The question makes no sense. From the documentation:
FrameLayout is designed to block out an area on the screen to display a single item.
Emphesis mine.
If you want your layout to contain more than one item, do not use a frame layout. Use something else.
