i don't know how to make this bar in the layout in android studio?
i want the XML code for this part of the activity.

You can use Seekbar to achieve a similar one. Please refer this for more information: https://developer.android.com/reference/android/widget/SeekBar.html
This is a sample xml:
<SeekBar
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginTop="26dp"
android:max="100" >
</SeekBar>
Feel free to customize the indicators. Also, this is a good tutorial: http://abhiandroid.com/ui/seekbar

I saw a special ripple effect in an app, i want to do it, too now. I attached a video to this ripple effect.
Any ideas or suggestions how I can do this?

You can use library for that
And wrap your view inside it
<com.andexert.library.RippleView
android:id="#+id/more"
android:layout_width="?android:actionBarSize"
android:layout_height="?android:actionBarSize"
android:layout_toLeftOf="#+id/more2"
android:layout_margin="5dp"
rv_centered="true">
<ImageView
android:layout_width="?android:actionBarSize"
android:layout_height="?android:actionBarSize"
android:src="#android:drawable/ic_menu_edit"
android:layout_centerInParent="true"
android:padding="10dp"
android:background="#android:color/holo_blue_dark"/>
</com.andexert.library.RippleView>

<EditText android:id="#+id/edit_message"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:hint="#string/edit_message" />
what is the purpose of #+id/edit_message? I am searching for it yet I haven't found a clear explanations.

This means you are creating a reference for the EditText so that it can be used in another View, layout file, or in your Java code.
To me, it is very much like declaring a variable in your code.
String ggjon = "New to android and need an explanation";
The difference between using #+id/edit_message and #id/edit_message is declaration vs. referencing an already declared View.

You define id for your TextEdit. Thanks to that You can access it via Java code:
EditText myedit = (EditText)this.findViewById(R.id.edit_message);

ProgressBar progressBar=new ProgressBar(this,null,android.R.attr.progressBarStyleHorizontal);
progressBar.setProgressDrawable(getResources().getDrawable(R.drawable.progress_bar));
progressBar.setMinimumWidth(100);

Try to change it from Resources, from XML.
<ProgressBar
android:id="#+id/progressBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:indeterminate="true" />
EDIT :
If you want to change it on runtime, take a look on this link.

I am creating an android application and would like to set up my activity to have a question with multiple answers that they could chose from. I was thinking radio buttons but I'm sure there is something more appropriate for this task. Example
Question
Answer1[x] Answer2[x] Answer3[x]

Use TextView for the question and ListView with multiple choices for the answers below
ListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);

Use CheckBox if the user can select multiple options.
RadioButtonis for when the user can only select one option.
As for layout:
It really depends, there are a lot of possible solutions, one possibility is:
<!--not all attributes are included,such as width and height, you have to add them-->
<LinearLayout android:orientation="vertical">
<TextView />
<LinearLayout android:orientation="horizontal"> <!--contains options-->
<CheckBox /> <CheckBox/> <CheckBox />
</LinearLayout>
</LinearLayout>
