在android中,我可以为不同的按钮使用相同的OnClickListener吗?如果是,如何获取点击是从哪个按钮生成的?我目前有4个按钮,每个按钮都有自己的OnClickListener。每个OnClickListener都在做同样的事情,只是获取被点击按钮的文本。我想创建一个OnClickListener,但我不知道如何确定正在单击哪个按钮。非常感谢。
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);
}
不同部分用粗体表示的侦听器代码
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);
}
};
手柄的代码Button click
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);
}
}
根据Karthik的建议,我将代码修改为以下内容:
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);
}
OnClickListener代码
private OnClickListener buttonClickListener = new View.OnClickListener() {
@Override
public void onClick(View arg0) {
handleButtonClick((Button)arg0);
}
};
