我在oncreate中创建了一个动态按钮,我没有在我的XML中放任何按钮。
LinearLayout table = (LinearLayout)findViewById(R.id.linearlayout);
Button btnAttendance,btnSched;
btnAttendance = new Button(this);
btnSched = new Button(this);
btnAttendance.setOnClickListener(this);
btnSched.setOnClickListener(this);
table.addView(btnAttendance);
table.addView(btnSched);
//这是我在实现我的监听器时创建的OnClick方法:
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
BackgroundWorker fetchRiddles = new BackgroundWorker(DashActivity.this,"retrieveRiddles");
switch (arg0.getId()) {
case 1: // in this case i usually put "R.id.Button1:" but my problem is that my buttons are dynamic
fetchRiddles.execute("0,"+username);
break;
case 2:
fetchRiddles.execute("1,"+username);
break;
}
如何确定使用开关点击了哪个按钮?我的按钮是动态创建的,不需要在我的xml中放任何按钮。
答案 0 :(得分:0)
您可以通过编程方式设置ID:
btnAttendance = new Button(this);
btnAttendance.setId(100);
btnSched = new Button(this);
btnSched.setId(200);
然后比较:
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
BackgroundWorker fetchRiddles = new BackgroundWorker(DashActivity.this,"retrieveRiddles");
switch (arg0.getId()) {
case 100: // in this case i usually put "R.id.Button1:" but my problem is that my buttons are dynamic
fetchRiddles.execute("0,"+username);
break;
case 200:
fetchRiddles.execute("1,"+username);
break;
}
