In android, can I use the same OnClickListener for different buttons? If yes, how do I get which button the click is generated from? I currently have 4 buttons and each button have their own OnClickListener. Each of the OnClickListener are doing the same exact thing with the exception of getting the text of the button being clicked. I want to create a single OnClickListener but I can't figure out how to determine which button is being clicked. Thank you
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
mTts = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
@Override
public void onInit(int arg0) {
// TODO Auto-generated method stub
}
});
setContentView(R.layout.home);
Button button1 = (Button)findViewById(R.id.button1);
Button button2 = (Button)findViewById(R.id.button2);
Button button3 = (Button)findViewById(R.id.button3);
Button button4 = (Button)findViewById(R.id.button4);
//Load First Word
button1.setOnClickListener(button1ClickListener);
button2.setOnClickListener(button2ClickListener);
button3.setOnClickListener(button3ClickListener);
button4.setOnClickListener(button4ClickListener);
}
Code for the listener with the the different part in bold
private OnClickListener button1ClickListener = new View.OnClickListener() {
@Override
public void onClick(View arg0) {
**Button button = (Button)findViewById(R.id.button1);**
handleButtonClick(button);
}
};
private OnClickListener button2ClickListener = new View.OnClickListener() {
@Override
public void onClick(View arg0) {
**Button button = (Button)findViewById(R.id.button2);**
handleButtonClick(button);
}
};
private OnClickListener button3ClickListener = new View.OnClickListener() {
@Override
public void onClick(View arg0) {
**Button button = (Button)findViewById(R.id.button3);**
handleButtonClick(button);
}
};
private OnClickListener button4ClickListener = new View.OnClickListener() {
@Override
public void onClick(View arg0) {
**Button button = (Button)findViewById(R.id.button4);**
handleButtonClick(button);
}
};
Code for handleButtonclick
private void handleButtonClick(Button button) {
if(button.getText().equals(currentWord)){
currentScore += availableScore;
TextView score = (TextView)findViewById(R.id.textViewScore);
score.setText(String.valueOf(score));
currentIndex++;
availableScore = 4;
InitializeGame();
}
else{
availableScore--;
button.setEnabled(false);
}
}
With recommendation from Karthik I modified my code to the following:
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
mTts = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
@Override
public void onInit(int arg0) {
// TODO Auto-generated method stub
}
});
setContentView(R.layout.home);
Button button1 = (Button)findViewById(R.id.button1);
Button button2 = (Button)findViewById(R.id.button2);
Button button3 = (Button)findViewById(R.id.button3);
Button button4 = (Button)findViewById(R.id.button4);
//Load First Word
button1.setOnClickListener(buttonClickListener);
button2.setOnClickListener(buttonClickListener);
button3.setOnClickListener(buttonClickListener);
button4.setOnClickListener(buttonClickListener);
}
OnClickListenerCode
private OnClickListener buttonClickListener = new View.OnClickListener() {
@Override
public void onClick(View arg0) {
handleButtonClick((Button)arg0);
}
};
