Linear Layout is not properly showing the component when using android studio

Linear Layout is not properly showing the component when using android studio - android

This is code
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">

android:layout_height="wrap_content"
android:text="Email:"

android:paddingLeft="0dp"
android:paddingTop="10dp"/>
<EditText
android:layout_width="150dp"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"
android:singleLine="true" />
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Login"
android:paddingTop="10dp"/>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="match_parent"

</LinearLayout>
I want to practice a layout in android studio and I'm getting an error while implementing the code.
This is the text which goes outside the mobile screen:
Why does the blue box go outside the mobile screen?

You're not properly setting the layout. The childViews of your parentView(LinearLayout) was aligned horizontally without setting the layout weight. You should read the documentation on LinearLayout. However, to fix your layout, you can add another container to hold the first row of your layout to make the second row visible on the screen. Your current code contains all the childViews in a single row which makes the other views not visible. Try the code below:
<?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">
<LinearLayout
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:layout_width="100dp"
android:layout_height="wrap_content"
android:text="Email:"
android:textSize="30dp"
android:paddingLeft="0dp"
android:paddingTop="10dp"/>
<EditText
android:layout_width="150dp"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"
android:singleLine="true" />
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Login"
android:paddingTop="10dp"/>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:layout_width="200dp"
android:layout_height="100dp"
android:text="Home" />
<TextView
android:layout_width="200dp"
android:layout_height="200dp"
android:text="About" />
</LinearLayout>
</LinearLayout>

You are setting the layout_width of each view yourself. You should know that there is a maximum width of screen that is available. Moreover, you are setting the width of button as match_parent that is not proper way when the neighbouring views have some fixed width. If your are using LinearLayout try layout_weight attribute. Play around and try to experiment.
For example:
<?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="match_parent"
android:orientation="horizontal">
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="2"
android:paddingLeft="0dp"
android:paddingTop="10dp"
android:text="Email:"
android:textSize="30dp" />
<EditText
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"
android:layout_weight="2"
android:singleLine="true" />
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="2"
android:paddingTop="10dp"
android:text="Login" />
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="2"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="100dp"
android:text="Home" />
<TextView
android:layout_width="wrap_content"
android:layout_height="200dp"
android:text="About" />
</LinearLayout>
</LinearLayout>

Height of ListView in dialog in android not set as per the number of items in ListView; results in blank space when there are less number of options

Result is appropriate when there are enough options; image-> result is ok, But when there are less options in listview then there will be empty space; which I don't want to be there.image-> not ok result
I want to set the height like, when there are less options, there should not be any blank space bw. cancel button and list view.

I can't use the other views like fragment and such, as then there will be lot of changes in my code.

You set the layout_weight to 10 which is not required here for list view we just want to use wrap_content in layout_height:-
<ListView
android:id="#+id/dialogList"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="10"
android:background="#drawable/listview_background"
android:choiceMode="singleChoice"></ListView>
Please check by Trying Recycler view instead of List View using my code:-

How do I align text to any position I want to align it to?

This is basically how I want my layout to look like:
There has to be a space separating the imageView from the Text. Ok button in the center, but I think the main challenge is making sure that the bold text is very closely aligned (almost touching the tip) to the regular text and is above it. Also, the added challenge is that all of this must be done using ONLY linear layout. So far, I have been using a vertical orientation linear layout followed by a horizontal orientation linear layout. The horizontal orientation linear layout covers the imageView and the regular text. My main problem is that I can not get the bold text and the regular text to align in the way I need it to.
By the way, I got rid of all the id's and images, since these are all private, but adding them should be no problem.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="wrap_content"

android:layout_height="wrap_content"

android:textColor="#color/black"
android:textSize="18sp"
android:textStyle="bold" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageView
android:id="#+id/"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="13dp"
android:layout_marginTop="12dp"

<TextView

Unless this is for a school project or something I wouldn't actually use nested layouts like this.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="wrap_content"
android:layout_weight="1"
android:adjustViewBounds="true"
android:cropToPadding="false"
android:scaleType="fitXY"
app:srcCompat="#drawable/ic_launcher_background" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="vertical">
<TextView
android:id="#+id/textView2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Bold Text"
android:textStyle="bold" />
<TextView
android:id="#+id/textView3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="TextView" />
</LinearLayout>
</LinearLayout>
<Button
android:id="#+id/button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>
Edit:
<ImageView
android:id="#+id/imageView2"
android:layout_width="wrap_content"
android:layout_height="10dp"
android:layout_weight="1"
android:adjustViewBounds="true"
android:cropToPadding="false"
android:scaleType="fitXY"
android:layout_gravity="center_vertical"
app:srcCompat="#drawable/ic_launcher_background" />

Parent should be vertical linear layout, as you have now.
First child should be horizontal linear layout
First child of that should be ImageView
Second child should be BOLD TEXT with gravity=center_horizontal
Second child of your parent should be Regular Text Blah Blah Blah with gravity=center_horizontal
Third child of parent should be ok button with gravity=center_horizontal
If you want to add more space before things, give them android:marginStart="some_value"

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageView
android:id="#+id/img"
android:layout_width="75dp"
android:layout_height="50dp"
android:layout_marginEnd="16dp"
android:src="#drawable/dummy_camera" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="#+id/tv1"
android:layout_width="match_parent"
android:layout_height="40dp"
android:text="Bold Text"
android:gravity="bottom"
android:textColor="#color/black"
android:textSize="18sp"
android:textStyle="bold" />
<TextView
android:id="#+id/tv2"
android:layout_width="match_parent"
android:layout_height="20dp"
android:gravity="top"
android:text="Regular Text"
android:textColor="#color/black" />
</LinearLayout>
</LinearLayout>
<Button
android:id="#+id/btn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Ok" />
</LinearLayout>

Add this to TextView parameters:
android:baselineAlignBottom="true"

Not blurry TextView in blurry Layout

I'm trying to put some TextViews on black-transparent layer.
To make the layout blurry, I set alpha(0.3) inside layout
It works well. The layout became transparent.
But the problem is that the textview inside the layout also becomes blurry.
How can I fix it?
<LinearLayout
android:layout_width="match_parent"
android:layout_height="30dp"
android:background="#E6000000"
android:alpha="0.3"
>
<TextView
android:id="#+id/text_feed_myPlant_name"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="Error"
android:textSize="19dp"
android:textColor="#FFFFFF"
android:layout_marginLeft="10dp"
android:layout_gravity="center_vertical"
android:layout_weight="1"/>
<TextView
android:id="#+id/text_feed_myPlant_time"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:textSize="14dp"
android:textColor="#FFFFFF"
android:gravity="right"
android:layout_gravity="center_vertical"
android:paddingRight="10dp"
android:layout_weight="1.5"/>
</LinearLayout>

What you can do is take a relative layout and take a view which covers all of it and set the aplha to that view.Then you can take your linear layout and set it as the second child of the relative layout.
<?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="wrap_content">
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:alpha="0.3"
android:background="#E6000000"
/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="30dp"
>
<TextView
android:id="#+id/text_feed_myPlant_name"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="Error"
android:textSize="19dp"
android:textColor="#FFFFFF"
android:layout_marginLeft="10dp"
android:layout_gravity="center_vertical"
android:layout_weight="1"/>
<TextView
android:id="#+id/text_feed_myPlant_time"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:textSize="14dp"
android:textColor="#FFFFFF"
android:gravity="right"
android:layout_gravity="center_vertical"
android:paddingRight="10dp"
android:layout_weight="1.5"/>
</LinearLayout>
</RelativeLayout>
I did this and it works fine.

I think this is Not really the best of doing it. But it will fix your problem
<FrameLayout
android:layout_width="match_parent"
android:layout_height="30dp"
android:background="#color/white">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#E6000000"
android:alpha="0.3"
>
<TextView
/>
<TextView
/>
</LinearLayout>

Why only one attribute in layout_gravity in my xml working

I want my reset button to be at bottom and horizontally centered, but layout_gravity is not working, only one of them is working.
I know it can be done by choosing RelativeLayout as my parent layout but I want to do it with LinearLayout as my parent layout.
I just want reset button as bottom and horizontally centered rest everything is fine.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="wrap_content"
android:layout_gravity="bottom|center_horizontal"
android:onClick="resetButton"
android:padding="8dp"
android:text="RESET" />
</LinearLayout>

Use this instead if you don't want to go completely relative (inside the parent Linear Layout):
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal|bottom"
android:onClick="resetButton"
android:padding="8dp"
android:text="RESET"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>
or if you don't want to keep the reset button inside a relative layout, there doesn't seem to be a solution.
You can check this out as well: How to align views at the bottom of the screen?

Since the rest of your ViewGroups in that layout fill the parent's width, you could simply set the parent LinearLayout's gravity to center_horizontal and it should line up properly, without affecting the other children:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center_horizontal"
tools:context="com.example.android.courtcounter.MainActivity">
Edit: I didn't notice you also wanted it at the bottom... This can be achieved with an invisible weighted View between your content and the bottom:
...
<View
android:layout_width="1dip"
android:layout_height="fill_parent"
android:layout_weight="1" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="resetButton"
android:padding="8dp"
android:text="RESET" />
</LinearLayout>
Edit 2: Removed layout_gravity on your button since it no longer applies.

textview overlapping in relativeLayout

I m having a Custom List for a chat application.
It has basically Two imageView in the either side and textView for the "chat message" in the middle.
Below all the three above there is textview for time at the bottom.
The screenshot below would better suffice.
The problem here is the time textView is overlapping over the imageView if the text of the "chat message" is only line.
This problem is better corrected with html-css as float clear:both.
I went through another answer for this with a nested RelativeLayout within LinearLayout here but i want to keep it clean with a single RelativeLayout.
The layout xml is as below -
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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/icon1"
android:layout_width="40dp"
android:layout_height="40dp"
android:src="#mipmap/ic_launcher" />
<TextView
android:id="#+id/msgText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="bottom"
android:textSize="20sp"
android:layout_marginLeft="42dp"
android:layout_marginRight="42dp"
android:text="this is a test" />
<ImageView
android:id="#+id/icon2"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_alignParentRight="true"
android:src="#mipmap/ic_launcher" />
<TextView
android:id="#+id/timeText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="40px"
android:layout_marginTop="10dp"
android:layout_below="#+id/msgText"
android:layout_alignParentRight="true"
android:gravity="right"
/>
</RelativeLayout>
The screenshot for this as below -

You have this:
android:layout_below="#+id/msgText"
Change to this:
android:layout_below="#id/icon2"
EDIT
Put a minHeight on your message TextView which is equal to the image height and don't change as I told you above.

You should use LinearLayout instead
The layout example which avatar on the left side
<?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="wrap_content"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<ImageView
android:id="#+id/avatar"
android:layout_width="50dp"
android:background="#ff0000"
android:layout_height="50dp" />
<TextView
android:id="#+id/content"
android:layout_width="0dp"
android:text="content here"
android:layout_height="wrap_content"
android:layout_weight="1" />
</LinearLayout>
<TextView
android:id="#+id/date"
android:layout_width="match_parent"
android:text="date here"
android:layout_height="wrap_content" />
</LinearLayout>
The layout example which avatar on the right side
<?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="wrap_content"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="#+id/content"
android:layout_width="0dp"
android:text="content here"
android:gravity="right"
android:layout_height="wrap_content"
android:layout_weight="1" />
<ImageView
android:id="#+id/avatar"
android:layout_width="50dp"
android:background="#ff0000"
android:layout_height="50dp" />
</LinearLayout>
<TextView
android:id="#+id/date"
android:layout_width="match_parent"
android:text="date here"
android:layout_height="wrap_content" />
</LinearLayout>
