TextView overlaps with another textview

I want the text to be displayed to the right of the name,but if the name is too large, the text on the right doesn't fit on the screen. I used the following solution, but it causes the first textview to stretch beyond the size of the text in it.

just remove android:weighSum="1" and android:layout_weight attribute in two textViews
enter code here<LinearLayout android:layout_width="match_parent"

How can I conditionally 'remove' or hide a button?

I have a fragment containing a recyclerView.
When an item is clicked on in the recyclerView I set the recyclerview item background to green and change the "saveBtn" text to "Update".
I need to also be able to remove the "deletebtn" every time a user clicks on a recyclerView item, or hide it so that the UI looks somewhat like this:
How could this be done?
Method I am using to update UI on recyclerView click
public void onExerciseClicked(int position) {
saveBtn.setText("Update");
clearBtn.setText("Delete");
}

Using LinearLayout as a direct child of ConstraintLayout defeats the whole purpose of using ConstraintLayout. It is not a good practice to use nested layout from the performance point of view. Besides, if deleteBtn is direct child of ConstraintLayout, then setting the layout_width of saveBtn to match_constraint will enable it to take up the whole space if we change the visibility of deleteBtn to gone.

cgb_pandey's answer is great and it is the recommended approach since your root viewgroup is ConstraintLayout. However, I wanted to present you an alternative way to do this using your current LinearLayout approach.
All you need to do is to set the width of both bottoms to 0dp. This way, their weight would determine how much space they occupy. If both view are visible, each of them would have 50% of the total width of the screen. If only one of the buttons is visible, it would occupy the entire screen. Here's a code snippet to guide you:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:orientation="horizontal">
<Button
android:id="#+id/save_btn"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_weight="1"
android:background="#drawable/my_small_green_shape"
android:text="Save"
android:textColor="#ffffff"
android:textSize="20sp" />
<Button
android:id="#+id/clear_btn"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_weight="1"
android:background="#drawable/my_small_red_shape"
android:text="Clear"
android:textColor="#ffffff"
android:textSize="20sp" />
</LinearLayout>
Not that this approach involves nesting layouts and this might affect performance in the long run and also complicate your layout code pretty fast.

How to align Two TextViews next to each other in LinnearLayouts?

I am trying to put two TextViews next to each other but somehow I can't get it to work. I wanted to have the following: txtViewAddress: txtAddress
I've tried putting android:layout_toRightOf="#id/txtViewAddress"
I also tried putting layout_toLeftOf, but both did not work.
Hope you guys can help me out. Thanks in advance.

If you need views inside a linear layout next to each other, the orientation of your layout must be horizontal.
You can also use the constraint layout, it has much more flexibility in placing view on your screen.

android:layout_toRightOf="#id/txtViewAddress" is atrribute part of Relative Layout
Use this code
<LinearLayout
android:layout_width="480dp"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/txtViewAddress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Address: "
android:textAppearance="?android:attr/textAppearanceMedium"
android:textSize="22dp"
android:textStyle="bold"/>
<TextView
android:id="#+id/txtAddress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toEndOf="#id/txtViewAddress"
android:text="Hello"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textSize="22dp"
android:textStyle="bold"/>
</LinearLayout>

<LinearLayout
android:layout_width="480dp"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="2">
<TextView
android:id="#+id/txtViewAddress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Address: "
android:layout_weight="1"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textSize="22dp"
android:textStyle="bold"/>
<TextView
android:id="#+id/txtAddress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toEndOf="#id/txtViewAddress"
android:layout_weight="1"
android:text="Hello"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textSize="22dp"
android:textStyle="bold"/>
</LinearLayout>
change the android:orientation="vertical" to android:orientation="horizontal"
and you can also use android:weightSum="2" weightSum is used to define the priority of the view
if you give equal weight to all views inside linear layout then all the views take on equal amount of space inside the Linear Layout

this should be like following
<LinearLayout
android:layout_width="480dp"
android:layout_height="wrap_content"
android:orientation="horizontal">
.....
......
.....
</LinearLayout>
and also I suggest that do not give fix width to layout instead you set it releted to screen size

How to put an image below textview in layout?

How can I put the image view below two of the text views, tv_pw and tv_un. So that in the layout the two text views are on top of the image, while the image serves as a background for that two text views. How could I do that?
Here is my xml file:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="510dip"
android:layout_marginTop="10dip"
android:background="#DDDDDD">"
<EditText
android:id="#+id/et_pw"
android:layout_width="150dip"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/et_un"
android:layout_below="#+id/et_un"
android:background="#android:drawable/editbox_background"
android:ems="10"
android:inputType="textPassword" />
<TextView
android:id="#+id/tv_pw"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/et_pw"
android:layout_alignBottom="#+id/et_pw"
android:layout_marginRight="20dp"
android:layout_toLeftOf="#+id/et_pw"
android:text="Password:"
android:textColor="#444444"
android:textSize="10pt" />
<Button
android:id="#+id/btn_login"
android:layout_width="100dip"
android:layout_height="wrap_content"
android:layout_below="#+id/et_pw"
android:layout_centerHorizontal="true"
android:text="Login" />
<TextView
android:id="#+id/tv_un"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignRight="#+id/tv_pw"
android:layout_marginTop="98dp"
android:text="User Name:"
android:textColor="#444444"
android:textSize="10pt" />
<EditText
android:id="#+id/et_un"
android:layout_width="150dip"
android:layout_height="wrap_content"
android:layout_alignTop="#+id/tv_un"
android:layout_centerHorizontal="true"
android:background="#android:drawable/editbox_background"
android:ems="10"
android:inputType="text" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/btn_login"
android:layout_centerHorizontal="true"
android:text="" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="32dp"
android:text="text"
android:textAppearance="?android:attr/textAppearanceLarge" />
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="14dp"
android:src="#drawable/bkground" />

There's a lot more in your XML but, focusing on what you are asking, you can use the margin attribute to overlap the textviews.
Try something like this
<RelativeLayout 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" >
<ImageView
android:id="#+id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/myImage">
</ImageView>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/image"
android:layout_marginTop="-50dp"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello_world" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello_world2" />
</LinearLayout>
</RelativeLayout>
In this example I wrapped the two textviews inside a linear-layout (vertical) and set the linear-layout below the imageview and a margin of -50dp so it goes up and overlap.

Another way would be to use drawableBottom="#drawable/ic_launcher" inside your textview

If you don't care about having control on how the image scales, you can set the background of a LinearLayout that's wrapped around the TextViews.
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/your_background_image_here"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/text_view_1" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/text_view_2" />
</LinearLayout>

Try this way,hope this will help you to solve your problem.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="510dp"
android:layout_marginTop="10dp"

android:gravity="center"
android:background="#DDDDDD">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="98dp">
<LinearLayout
android:layout_width="110dp"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#drawable/bkground">

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="User Name:"

android:layout_height="wrap_content"
android:layout_marginTop="32dp"
android:text="text"
android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>

Wrap the two TextViews in linear layout with vertical orientation and assign background for linear layout.

use android:weight on the the two text views and boom

<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content" />

How can I align my ImageView with my TextView in a LinearLayout?

I have the following ImageView and TextView:
Here is the XML:
<LinearLayout android:layout_height="wrap_content" android:layout_width="match_parent" android:id="#+id/headerLinearLay" android:orientation="horizontal">
<ImageView android:src="#drawable/icon" android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="#+id/avatarImageView"></ImageView>
<TextView android:layout_height="wrap_content" android:id="#+id/usernameTextView" android:text="TextView" android:layout_width="wrap_content" android:paddingLeft="4px"></TextView>
</LinearLayout>
How can I make the image and the text be positioned at the same height? I also want the ImageView to be in the corner

Try this:
<RelativeLayout
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:id="#+id/headerLinearLay">
<ImageView
android:id="#+id/avatarImageView"
android:src="#drawable/icon"
android:layout_height="wrap_content"
android:layout_width="wrap_content"></ImageView>
<TextView
android:id="#+id/usernameTextView"
android:text="TextView"
android:paddingLeft="4dp"
android:layout_toRightOf="#id/avatarImageView"
android:layout_centerVertical="true"
android:layout_height="wrap_content"
android:layout_width="wrap_content"></TextView>
</RelativeLayout>

Here is a simple solution that works well. Essential here is to add: android:layout_gravity="center_vertical" to TextView
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/icon" />
<TextView
android:id="#+id/usernameTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical" />
</LinearLayout>

<TextView
android:id="#+id/textView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="TextView"
android:layout_weight="0.04" />
<ImageView
android:id="#+id/imageView"
android:layout_width="204dp"
android:layout_height="200dp"
app:srcCompat="#mipmap/ic_launcher" />
