Android studio how to know which textview was clicked?

I'm basically building a small quiz app and for every question, there are 4 answers in 4 different textviews. What I want to know is which textview has been clicked by the user.

Try This : 

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;

import com.example.dgnc.testproject.R;

public class YourClass extends AppCompatActivity implements View.OnClickListener{
TextView view1,view2;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    view1 = (TextView)findViewById(R.id.text);
    view2 = (TextView)findViewById(R.id.text2);
    view1.setOnClickListener(this);
    view2.setOnClickListener(this);

}

@Override
public void onClick(View v) {
    Toast.makeText(getApplicationContext(),"clicked textView : 
               "+v.getId(),Toast.LENGTH_LONG).show();
    switch (v.getId()){
        case R.id.text : 
            // do somthing
            break;
        case R.id.text2 : 
            //do somthing
            break;
    }

}

}

You can give different id's to your TextViews and set onclickListener the following way

 TextView textView=(TextView)findViewById(R.id.textView);
        textView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

            }
        });

and then perform any of the task you want.Here you can use if else statement in order to check the answer afterwards.

You can easily do this by applying onClickListeners to the textViews, Following code may help :

TextView mTvAnswer1, mTvAnswer2, mTvAnswer3, mTvAnswer4;
mTvAnswer1 = findViewById(R.id.text_1);
// similarly find other textviews

mTvAnswer1.setOnClickListener(this);
mTvAnswer2.setOnClickListener(this);
mTvAnswer3.setOnClickListener(this);
mTvAnswer4.setOnClickListener(this);

And after this in you can override onClick() as follows:

@Override
public void onClick(View v){
switch (v.getId()){
     case R.id.text1:
         // First option clicked
         break;
     case R.id.text2:
        // Second option clicked
        break;
     case R.id.text3:
         // Third option clicked
         break;
     case R.id.text4:
         // Fourth option clicked
         break;

} }

There are many, many ways to do this. The simplest thing would be create a method that takes one parameter, than each TextView's OnClickListener will call that method with different parameter.

private final View.OnClickListener mOnOptionClickListener = 
    new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            onOptionClicked(v.getTag());
        }
    });

private void onOptionClicked(final int optionNumber) {
    // take care of it
}

protected void onCreate(...) {
    // after all your textviews are bound... 
    textView1.setTag(1);
    textView2.setTag(2);
    textView3.setTag(3);
    textView4.setTag(4);

    textView1.setOnClickListener(mOnOptionClickListener);
    textView2.setOnClickListener(mOnOptionClickListener);
    textView3.setOnClickListener(mOnOptionClickListener);
    textView4.setOnClickListener(mOnOptionClickListener);
}
