在
android中,可以使用相同的OnClickListener来进行不同的按钮吗？如果是,如何获取点击生成的按钮？我目前有4个按钮,每个按钮都有自己的OnClickListener.每个OnClickListener都做同样的事情,除了获取点击的按钮的文本.我想创建一个单一的OnClickListener,但是我不知道如何确定哪个按钮被点击了.谢谢
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);
}
侦听器的代码与粗体不同的部分
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);
}
};
handleButtonclick的代码
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);
}
}
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);
}
};
解决方法
是的,这是可能的.我下面写了一个例子,应该比较简单.
像往常一样,为所有按钮添加OnClickListener,如下所示：
btn1.setOnClickListener(this); btn2.setOnClickListener(this); btn3.setOnClickListener(this);
然后添加onClick()事件,如下所示：
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(v == btn1){
//Things to do
}
if(v == btn2){
//Things to do
}
if(v == btn3){
//Things to do
}
}
这应该是正常的.不要忘记为您的onCreate所在的类隐含View.OnClickListener,否则所有设置OnClickListener的语句将不正确.
