Hello I am using this code and for some reason the button doesn't show up. Why? Also I tried switching the setcontentView(); to the button. But when that happens the text doesn't show up. How do I show both?
Code:
package com.kmccmk9.CarVoice;
import java.util.Locale;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.Intent;
import android.widget.Button;
import android.widget.TextView;
import android.os.Bundle;
import android.speech.tts.*;
import android.speech.tts.TextToSpeech.OnInitListener;
public class CarVoice extends Activity implements OnInitListener {
/** Called when the activity is first created. */
private TextToSpeech tts;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView lbl_tv = new TextView(this);
lbl_tv.setText("Welcome to Car Voice. This app was designed for you to never have to use your hand for your phone while you are in the car.");
lbl_tv.setTextSize(28);
setContentView(lbl_tv);
Button cmd_Button = new Button(this);
cmd_Button.setText("Command");
AlertDialog.Builder safetybuilder = new AlertDialog.Builder(this);
safetybuilder.setMessage("Do not use this app while the vehicle is in motion. Doing so can seriously injur yourself or someone else. We are not responsible for anything that may happen. Please use this at your own risk.");
safetybuilder.setCancelable(false);
safetybuilder.setPositiveButton("Agree", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
dialog.cancel();
}
});
safetybuilder.setNegativeButton("Close", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
System.exit(0);
}
});
AlertDialog safety = safetybuilder.create();
safety.show();
Intent checkIntent = new Intent();
checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(checkIntent, 0);
tts = new TextToSpeech(this, this);
}
public void onInit(int arg0) {
// TODO Auto-generated method stub
String speech1 = "Do not use this app while the vehicle is in motion, Doing so can seriously injur yourself or someone else, We are not responsible for anything that may happen, Please use this at your own risk.";
String speech2 = "To use this app, Touch the command button, listen to the prompt and say your response, You can say things like, text, phone, or navigation.";
tts.setLanguage(Locale.US);
tts.speak(speech1, TextToSpeech.QUEUE_FLUSH, null);
tts.speak(speech2, TextToSpeech.QUEUE_ADD, null);
}
}
