How to perform onclick action on multiple buttons created dynamically in Android Studio

I am new to android and i want to create a workout application for my own use and for that my idea was-

1) The main activity will display an add button to add number of exercises. Lets suppose i need 5 exercises so 5 buttons will be create dynamically.

2) Now buttons are created what i need is when i click on any button the corresponding textToSpeech is called because this textToSpeech class will speak the name of exercise to be started. As each button is associated with a different exercise name and time.

Activity images-- Main Activity , Add number of Buttons

I don't Know how to do this as there are lots of button and how to call different textToSpeech for each buttons.

just add onCLickListener in your activity

View.OnClickListener onClickListener=new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // put condition as per id of view
            }
        };

// here while creating dynamically add click listner

Button button=new Button(ButtonActivity.this);
        button.setText("Button"+i);
        button.setId(1000+i);
        button.setOnCLickListener(onClickListener);

I hope i gave you solution.

SecondActivity(Button display) No need to create Activity Create Java file and add the file in manifest

GridLayout gridLayout=new GridLayout(this);
    ViewGroup.LayoutParams layoutParams=new ViewGroup.LayoutParams(GridLayout.LayoutParams.MATCH_PARENT,GridLayout.LayoutParams.WRAP_CONTENT);
    gridLayout.setLayoutParams(layoutParams);
    gridLayout.setColumnCount(2);
    setContentView(gridLayout);
    if(getIntent()!=null){
        int buttoncount=getIntent().getIntExtra("value",0);
        for(int i=0;i<buttoncount;i++){
           Button button=new Button(ButtonActivity.this);
            button.setText("Button"+i);
            button.setId(1000+i);
            button.setBackgroundResource(R.drawable.button_back);
            button.setPadding(10,10,10,10);
            gridLayout.addView(button);
        }
    }

Xml file for background (create this file inside of drawable)

 <?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#66ff0000" />
<size
    android:width="120dp"
    android:height="120dp"/>
</shape>

Any confusion then use this is full code of Java file

public class ButtonActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    GridLayout gridLayout=new GridLayout(this);
    ViewGroup.LayoutParams layoutParams=new ViewGroup.LayoutParams(GridLayout.LayoutParams.MATCH_PARENT,GridLayout.LayoutParams.WRAP_CONTENT);
    gridLayout.setLayoutParams(layoutParams);
    gridLayout.setColumnCount(2);
    setContentView(gridLayout);
    if(getIntent()!=null){
        int buttoncount=getIntent().getIntExtra("value",0);
        for(int i=0;i<buttoncount;i++){
           Button button=new Button(ButtonActivity.this);
            button.setText("Button"+i);
            button.setId(1000+i);
            button.setBackgroundResource(R.drawable.button_back);
            button.setPadding(10,10,10,10);
            gridLayout.addView(button);
        }
    }

}
}

Manifest file

<activity android:name=".ButtonActivity"></activity>

and use the background file above...

Add clicklistener while inflating new button/view.

    private void addNewExcercise(String exercise) {

    Button button = new Button(ActivityMain.this);
    button.setText(exercise);

    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // do ur task here
        }
    });

    parentLinearLayout.addView(button);
}

If I understand your problem in right manner you need to assign Ids to button while creating the buttons start loop for five buttons

for(i=1;i<=5;i++){
   Button button=new Button(Activity.this);
   button.setId(R.id.existingButtonId+i);
   button.setWidth(LinearLayout.LayoutParams.MATCH_PARENT);
   button.offsetTopAndBottom(40);
   button.setHint("hint x ");
   yourLayout.addView(button);
 }

after this implement onClickListener on your activity and use 

public void onClick(View v) {
    switch (v.getId()) {
        case R.id.ex1:
             //call textToSpeech for exercise one
            break;
        case R.id.ex2:
            //call textToSpeech for exercise two
            break;
        default:
            break;
    }
}

            break;

        case R.id.threeButton:
