该elseif(v == button2)行给出错误,指出"令牌上的语法错误'==',删除此令牌".我从这个网站的主题"变量OnClick监听器android"中得到了这个想法.谁能告诉我如何使用它？
这是我的代码:
View.OnClickListener yourListener = new View.OnClickListener(){
public void onClick(View v){
if( v == button1){
new AlertDialog.Builder(this)
.setTitle("Paracettamol")
.setMessage("This medicine is generally used to cure Fever")
.setNeutralButton("OK", null)
.show();}
}
elseif( v == button2){
new AlertDialog.Builder(this)
.setTitle("sertraline")
.setMessage("This medicine is generally used to cure Head aches")
.setNeutralButton("OK", null)
.show();
}
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
}
} ;
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
}
}
上面提到的问题的答案有以下代码:
Button btn1, btn2;
public void onCreate(Bundle b)
{
// here you do normal things like assigning a
// content view to the activity, initiate buttons, etc.
// then you assign the same listener to both buttons
btn1.setOnClickListener(yourListener);
btn2.setOnClickListener(yourListener);
}
// declare a OnClickListener that will execute different actions
// depending on the view that was clicked
View.OnClickListener yourListener = new View.OnClickListener(){
public void onClick (View v){
if( v == btn1 ){
// do something
}
elseif( v == btn1 ){
// do another thing
}
}
};
