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();
}
}
And here is the content of activity_main.xml

Calculation using Textwatch

the question I going to ask, might be kind of complicated.
Pardon me, if I can't explain it clearly.
It's my first time having touch with android coding.
I would like to do a calculation doing android .
It's about Fuel Log.
What I want to do right now is
When I keep in the price(edittext) and pump(edittext),
the output will be shown straight away in the cost(textview), that I've placed.
I would want to do that,
but I don't think I have did the right coding for it.
I've tried out myself,
but I didn't run the application, cause I think that the codes I've done is not fully completed/right.
I would love to hear the advice from you guys.
Could someone please help me out with it?
Thank you,
your help will be much appreciate.
(:

add change lister to both edit text
priceEdit.addTextChangedListener(mCostChangeWatcher);
pumpEdit.addTextChangedListener(mCostChangeWatcher);
TextWatcher mCostChangeWatcher = new TextWatcher() {
#Override

}
}
};

Dialog + callback?

I have made a CustomTypeDialog class and what I want is to use EditText which is not in the active layout. I get a nullpointer exception when I try to click one of the buttons, which I think is because they are not in the active layout. Can you help me solve this? The dialog is called in an activity from another class.
package dk.droidrun.droidrunapp;
import android.app.Dialog;
import android.content.Context;
import android.content.DialogInterface;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageButton;
public class CustomTypeDialog extends Dialog {
ImageButton routeType;
EditText txtType;
Button imageRun, imageBike, imageWalk;
public CustomTypeDialog(final Context context) {
super(context);
this.setContentView(R.layout.customtype_dialog);
routeType = (ImageButton)findViewById(R.id.saveRoute_activityType);
txtType = (EditText)findViewById(R.id.saveRoute_typeTxt);
imageRun = (Button)findViewById(R.id.dialog_btn1);
imageBike = (Button)findViewById(R.id.dialog_btn2);
imageWalk = (Button)findViewById(R.id.dialog_btn3);
setTitle("Select activity type");
show();
imageRun.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
txtType.setText("Run");
routeType.setBackgroundResource(R.drawable.track_run);
}
});
imageBike.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
txtType.setText("Bike");
routeType.setBackgroundResource(R.drawable.track_bike);
}
});
imageWalk.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
txtType.setText("Walk");
routeType.setBackgroundResource(R.drawable.track_walk);
}
});
}
}

You cannot access views from another layout (your activity) using findViewById within the dialog view.
You need to add a callback listener for when the buttons on your dialog are clicked:
public interface OnDialogClickListener {
void onDialogImageRunClick();
}
public class CustomTypeDialog extends Dialog {
private final OnDialogClickListener listener;
public CustomTypeDialog(final Context context, OnDialogClickListener listener) {
this.listener = listener;
}
....
imageRun.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
listener.onDialogImageRunClick();
}
);
}
Then when you create your dialog in your Activity where you have access to the view:
new CustomTypeDialog(context, new CustomTypeDialog.OnDialogClickListener() {
#Override
public void onDialogImageRunClick() {
txtType.setText("Run");
routeType.setBackgroundResource(R.drawable.track_run);
}
});
