Widgets aren't being casted. how do I fix it?

Whenever I click the sign in button in my app, it just crashes and shows an error. Here is my activity_sign_in.xml and my SignIn.java.

"Caused by: java.lang.ClassCastException: android.support.v7.widget.AppCompatTextView cannot be cast to com.rey.material.widget.TextView"

Check your imports in SignIn.java. You are probably importing com.rey.material.widget.TextView instead of android.widget.TextView.
If you want to use the com.rey TextView instead of the normal one you have to write
<com.rey.material.widget.TextView
android:id="#+id/txtForgotPwd"
android:textColor="#android:color/white"
...
in your xml.

This is the code MainActivity.java file. I think there should be no mistake in this code. But it shows the message
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'android.view.Window$Callback android.view.Window.getCallback()' on a null object reference.
I don't know why it is showing up there? Please help me to figure out.

Here is the image of it should look like it is the screenshot the preview

All these findViewById must be included in your onCreate() method. You can keep the declarations out of onCreate(). Your views do not exist before setContentView(R.layout.activity_main);
I mean before onCreate() you can have Button b1;
and after setContentView(R.layout.activity_main); in onCreate() you must have b1=(Button)findViewById(R.id.b_i1);
for every view.

I have made the corrections in your and now the app is not crashing. Try using the below code snippet
MainActivity
public class MainActivity extends AppCompatActivity {
int score = 0, wickets = 0;
String value = null, number = null;
Button b1;

and this is spinner item
<string-array name="secim">
<item> YAZI </item>
<item> RESİM </item>
<item> VİDEO </item>
</string-array>
Any help would be appreciated.

You have to show and hide buttons on spinner selection in your Activity class. Set "OnItemSelectedListener" to your spinner, it will override few methods. In overridden "OnItemSelected" method hide the button like this:
yourButton.setVisibility(VISIBILTY.GONE);

I would like to add the previous answer as a comment. But the reputation is inadequate.
Actually it should be like this:
Use for hide: resimButonu.setVisibility(View.GONE);
or resimButonu.setVisibility(INVISIBLE);
use for show: resimButonu.setVisibility(View.VISIBLE); or resimButonu.setVisibility(VISIBLE);

thanks but i have 4 button and text i need :
if RESİM selected show 2 button
if * YAZI * selected show textbox
if *VİDEO * selected show 2 button
i have 4 button in app
ArrayAdapter adapter = ArrayAdapter.createFromResource(this, R.array.secim, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
camerax.setVisibility(View.VISIBLE);
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}

There is nothing in your activity layout with android:id="#+id/LinearContainer, and so FragmentManager does not have anywhere to place your DetailsFragment.
