开发中经常会遇见在一个编辑框或者文本框中选择日期，点击一个文本框弹出一个日期选择器的组件，在此基础上进行选择，废话少说，直接上代码：
先定义两个常量，后面选择的时候会用到
private static final int DIALOG = 1 ;
private static final int DIALOG2 = 2 ;
定义点击事件
View.OnClickListener datatextlist = new TextOnClickListener(DIALOG) ;
View.OnClickListener datatext2list = new Text2OnClickListener(DIALOG2) ;
text.setOnClickListener(datatextlist);
text1.setOnClickListener(datatext2list) ;
定义显示的对话框以及显示的日期
public Dialog onCreateDialog(int id){
Calendar calendar = Calendar.getInstance() ;
Dialog dialog = null ;
switch(id){
case 1 :
DatePickerDialog.OnDateSetListener datatextlist = new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker picker, int year, int month, int dayOfMonth) {
text.setText(year+"-"+(month+1)+"-"+dayOfMonth) ;
}
};
dialog = new DatePickerDialog(MainActivity.this, datatextlist, calendar.get(Calendar.YEAR),
calendar.get(Calendar.MINUTE), calendar.get(Calendar.DAY_OF_MONTH)) ;
break;
case 2 :
DatePickerDialog.OnDateSetListener datatext2list = new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker pick, int year, int month, int dayOfMonth) {
text1.setText(year+"-"+(month+1)+"-"+dayOfMonth) ;
}
};
dialog = new DatePickerDialog(MainActivity.this, datatext2list, calendar.get(Calendar.YEAR),
calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH)) ;
break ;
}
return dialog ;
}
以下是实现点击事件显示对话框
private class TextOnClickListener implements View.OnClickListener{
private int dialogId = 0; //默认为0则不显示对话框
public TextOnClickListener(int dialogId) {
this.dialogId = dialogId;
}
@Override
public void onClick(View view) {
showDialog(dialogId);
}
}
private class Text2OnClickListener implements View.OnClickListener{
private int dialogId = 0; //默认为0则不显示对话框
public Text2OnClickListener(int dialogId) {
this.dialogId = dialogId;
}
@Override
public void onClick(View view) {
showDialog(dialogId);
}
}
