Help please. The error does not link to some error in my code, i'm so confused

You must register your MotorActivity activity in your manifest.
<activity android:name=".MotorActivity" />

As i can see the above code,
if you are using Activity then you don't
need to use getApplicationContext() instead
of this you should use this.ActivityName or only this
because Context is define for their specific reason like
example if you are using fragment then you can use context
from onAttach and for Apdater you can use application context.
Please share your error without error i am not sure what is the reason of crash in your app.
for reference check this answer : Android button onClick changing activity cause app to crash
and for context description :- https://medium.com/#banmarkovic/what-is-context-in-android-and-which-one-should-you-use-e1a8c6529652

Always position "GOT IT" button of MaterialShowcaseView on the bottom left corner of the screen

I'm using the following library: https://github.com/deano2390/MaterialShowcaseView
I've been trying to find a way (for 2 days straight!) to always position the "GOT IT" button on the bottom left corner of the screen. How do I achieve that simply and effectively?
I will immediately accept the working answer. As you can see, I have a history of always accepting answers.
With Osama's answer, I get error:

This lib is based on ShowcaseView, take a look at it.
You can also go to the showcase_content.xml at the library module and put the tv_dismiss that is the "GOT IT" TextView into a RelativeLayout like this:

</LinearLayout>
Go to MaterialShowcaseView.java and empty the applyLayoutParams() method and update the setDelay to 1000

Within the builder, add the following code.
mDismissButton.setGravity(Gravity.BOTTOM);

ClassCastException from View objects in android studio

In Android Studio, when i try to run my project i get a ClassCastException as following:
Caused by: java.lang.ClassCastException: android.widget.EditText cannot be cast to android.widget.RelativeLayout
when the View object is 100% RelativeLayout and not EditText.
The problem occurs on another View element if i comment out the above-related code..
I have tried cleaning and rebuilding the project, i have tried editing the XML file and change the ID, i have tried deleting the XML file and restarting Android Studio and then make a new XML file, all that to no avail.
Thank you for your help.
EDIT
When i add new views to the xml, with id that i never used, somehow the activity before it gets nulls on its own (and totally seperate) xml file.. this is weird because theres no reason why a simple view on a different xml file should impact another xml that is loaded even before it..
EDIT2
I inspected View rl = activityView.findViewById(R.id.notification); and found out that it gets etMessage which is another view element in the same XML and is infact an EditText type view.
The code before the exception occurs:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setInitialView();
}
private void setInitialView() {
RelativeLayout frame = (RelativeLayout) findViewById(R.id.activity_frame);
LayoutInflater layoutInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View activityView = layoutInflater.inflate(R.layout.chat, null,false);
frame.removeAllViews();
frame.addView(activityView);
chatMap.put("Public", new ArrayList<ChatMessageBox>());
// move the notification layout outside the screen
RelativeLayout rl = (RelativeLayout) findViewById(R.id.notification);
TranslateAnimation moveAnim = new TranslateAnimation(
TranslateAnimation.ABSOLUTE, 0, TranslateAnimation.ABSOLUTE, 0,
TranslateAnimation.RELATIVE_TO_SELF, 0, TranslateAnimation.RELATIVE_TO_SELF, -1);
moveAnim.setDuration(0);
moveAnim.setFillAfter(true);
rl.startAnimation(moveAnim);
}
This activity's parent XML, which is loaded with setContentView in its onCreate:
<?xml version="1.0" encoding="utf-8"?>

The problem was probably with the cache of the application in the device itself.
I ran the application on a different device and there was no issue, so i cleared the data and cache from the device (Settings -> Apps) and uninstalled the app (just uninstalling didnt work), and now it works.

Change your onCreate like this:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.yourLayoutXmlName);
setInitialView();
}
Edit:
Try changing this line:
RelativeLayout rl = (RelativeLayout) findViewById(R.id.notification);
to
RelativeLayout rl = (RelativeLayout) activityView.findViewById(R.id.notification);
Hope it helps you.

R.id.activity_frame
does not exists in your xml file. Try to resolve this.
And post the complete code.

I don't know why it happens. Is there any solution? Thank you.

This is related to the way AppCompat inflates your layout. Try adding a programmatic onClick listener to your buttons rather than doing it within XML.
There's a discussion about it on Google Code. It's because you are using the AppCompat Buttons.

You could use butterknife annotations instead
#OnClick(R.id.IdForAppCompatButton)
public void doAction() {doSomething();}

In my case the problem was from setting the android:theme attribute to the view, (and also is related to the AppCompat library ... see #Peter Marozzi's answer).
So I simply removed the android: namespace from this line (from the view's style):
<item name="android:theme">#style/someTheme</item>
and make it likes:
<item name="theme">#style/someTheme</item>
and it works fine.
The interactive note is the problem is only on high-level APIs (23 I tested) and on low-level APIs (16 and 19 I tested) both methods (with or without android: namespace) work.

It worked for me to register the listener on the current DialogFragment class:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
dialogView = inflater.inflate(/*your layout*/, container, false);
dialogView.findViewById(R.id.close_button).setOnClickListener(this);
return dialogView;
}
#Override
public void onClick(View v) {
//Handle the button click event here
}

I keep getting an error message when running my app?

This is the error message I keep getting when I run my app in the emulator.
There's nothing in the Error Log and it doesn't really tell me where the error is coming from but I get this in the LogCat:
WARN/ActivityManager(51): Launch timeout has expired, giving up wake lock!

This is my Java for the Layout that comes up when the app is started: (I would think if this is what comes up first, that would be where the problem is, but I really don't know.)

import android.content.Intent;

import android.view.View;
import android.widget.TextView;
public class FirstActivity extends Activity {

super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView next1 = (TextView) findViewById(R.id.signuptext);
next1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent myIntent = new Intent(view.getContext(), Screen2.class);
startActivityForResult(myIntent, 0);
finish();
}
});
}
}
