EditText not focusing, and not showing keyboard after keyboard is hidden after one input

I am implementing an OTP Verification system and have 3 EditText fields in my layout, and one of them is hidden until the user clicks a button.
Here is the layout file:

The problem I am having is that when the third otp EditText is shown it doesn't show the virtual keyboard or gets focused when clicked. Instead I have to first click one of the previous two EditTexts for it to show the virtual keyboard.
What can I do to make the virtual keyboard show on clicking the OTP field at once?
Here is the java file.

}
};
}
}

Put this line when you want to give it focus:
otpField.requestFocus();
Also, to show the soft keyboard explicitly, you can do like below:
otpField.postDelayed(new Runnable() {
#Override
public void run() {
InputMethodManager im = (InputMethodManager)
getSystemService(Context.INPUT_METHOD_SERVICE);
im.showSoftInput(otpField, InputMethodManager.SHOW_IMPLICIT);
}
},200);

App keeps crashing every time i click the Log in Button

I am new to android, i was following some tutorial and at this point, app keeps crashing when i click the login button.
When i run the app and click the login button, the app crashes and in the logcat, it shows this error of java RuntimeException.
This is my logcat, loginactivity.xml and loginactivity.java.

It looks like you're defining standard Android components in the XML layout, then attempting to inflate them into custom components (the com.rey.material package). Try going into your imports and deleting the com.rey.material lines. Then when your IDE prompts you to import the TextView and Checkbox, make sure you're importing the versions from android.widget, not com.rey.material. Alternatively, you could change your XML file to specify the com.rey.material components if you wanted to be using those instead of the default ones.

You used the wrong import so you need to
replace this import
import com.rey.material.widget.TextView;
with
import android.widget.TextView;
OR
You can use the corresponding view in the XML
Replace
<TextView
android:id="#+id/forget_password_link"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Forget Password"
android:textColor="#color/colorPrimaryDark"
android:textSize="15sp"
android:textStyle="bold"
android:layout_marginLeft="80dp"
/>
with
<com.rey.material.widget.TextView
android:id="#+id/forget_password_link"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Forget Password"
android:textColor="#color/colorPrimaryDark"
android:textSize="15sp"
android:textStyle="bold"
android:layout_marginLeft="80dp" />
in your XML file

Looks like you are using the AppCompat Button in your XML, but using the material button in your java code.
So they need to be the same.
First you need to use the right import for whatever view you're using, if you want to use the AppCompat button then import like this
import android.widget.Button;
If you want to use the Material button, then use this import:
import com.rey.material.widget.Button;
Same thing goes for the TextView.
Hope this helps!

androidx.appcompat.widget.AppCompatTextView cannot be cast to
com.rey.material.widget.TextView
In your xml, you're using the SDK TextView but in your code, you want the com.rey.material.widget one.
--> Change one of these

How to set imageViews to single clicks rather than double

My android app includes a true/false game.
The user should click either the true or false image one time and the next statement will appear.
I need the user to click the image only once, but it is only allowing for double clicks.
Is there anyway to set the clicks to be single rather than double?
I have checked that the focusable and focusable in touch attributes are null

You can set your view to not be focusable with view.setFocusable(false), because if they are focusable, the first touch will "focus" them (which has no effects on ImageViews) and the second will call the onClick()-method.
If it is set to false, you will just need one click to call your onClick()-method.

Clicking register causes android app to crash

Clicking on register makes the app crash when the email and password fields are empty, but when the name field is empty it works properly what seems to be the problem?

and this is what is supposed to be happening: (works perfectly in name text but not in other edittexts)
screenshot of mobile app
any help will be appreciated :D

My guess is that it has something to do with what you put into #style/TextLabel.
When you have an error with password or email you request focus programmatically. Which is fine, however when that happens something in your style is looking for a color resource which doesn't exist. That's what's causing the error.

The error seems to be for getColor() method of textview, your primary color has some problem, please check that.

How do you turn a set string into speech in android studio?

I'm trying to find out how to set a string that will be read out-loud.
For example:
String text = "Hello";

You can find a very detail example that show how to convert text to speech on this site. HTH.
Your MainActivity.java should look something like this
import android.app.Activity;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import java.util.Locale;
import android.widget.Toast;
public class MainActivity extends Activity {
TextToSpeech t1;
EditText ed1;
Button b1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ed1=(EditText)findViewById(R.id.editText);
b1=(Button)findViewById(R.id.button);
t1=new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if(status != TextToSpeech.ERROR) {
t1.setLanguage(Locale.UK);
}
}
});
b1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String toSpeak = ed1.getText().toString();
Toast.makeText(getApplicationContext(), toSpeak,Toast.LENGTH_SHORT).show();
t1.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null);
}
});
}
public void onPause(){
if(t1 !=null){
t1.stop();
t1.shutdown();
}
super.onPause();
}
}
