I need help with this Android Studio Project

I need to implement these 2 steps:

Step 1 Implement Next button

In the onClick method for the Next button, you need to do two things:

1. Update the current index (mCurrentIndex) by increasing its value by 1. However, there are only 3 questions in the array. Therefore, you need to adjust the index accordingly.
2. Update the text in the text view for showing the question.

Step 2. Implement True/False buttons

In the onClick method for the True and False buttons, you need to update the text in the text view showing either correct or incorrect based on which button the user clicks and the answer of the question. Remember, you need to use the string in the resources to update the text.

Below are the codes:

Java Code:

package n01059882.unf.edu; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.TextView; public class MainActivity extends AppCompatActivity { private TextView mQuestionTV; private TextView mAnswerTV; private Button mTrueButton; private Button mFalseButton; private Button mNextButton; private int mCurrentIndex = 0; private int [] mQuestionBank = new int [] { R.string.question_text1, R.string.question_text2, R.string.question_text3 }; private boolean [] mAnswerBank = new boolean[] { true, false, true }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mQuestionTV = (TextView)findViewById(R.id.question_textView); mQuestionTV.setText(R.string.question_text1); mAnswerTV = (TextView)findViewById(R.id.answer_text_view); mAnswerTV.setText(R.string.answer_text); mTrueButton = (Button)findViewById(R.id.true_button); mTrueButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { } }); mFalseButton = (Button)findViewById(R.id.false_button); mFalseButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { } }); mNextButton = (Button)findViewById(R.id.next_button); mNextButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { mAnswerTV = +1; mAnswerTV.setText([] mAnswerBank); } }); }//end method }//end class 

The xml Code:

The String (Resource) Code:
