1、Dialog的使用
【1】AlertDialog的使用
1）新建一个AlertDialog.Builder对象
AlertDialog.Builder ad = new AlertDialog.Builder(this);
2）设置标题
ad.setTitle("It‘s Pitch Black");
3）设内容
ad.setMessage("HelloWorld");
4）加按钮
ad.setPositiveButton("Back",new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
System.out.println("Back");
}
});
ad.setNegativeButton("Next", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
System.out.println("Next");
}
});
5）设可取消（可以不设置）
ad.setCancelable(true);
ad.setCancelable(true);
ad.setOnCancelListener(new DialogInterface.OnCancelListener() {
@Override
public void onCancel(DialogInterface dialog) {
System.out.println("Cancel");
}
});
6）show展示
ad.show();
【2】特殊的输入Dialog
1)DatePickerDialog 可以让用户选择一个日期
Calendar calendar = Calendar.getInstance();
DatePickerDialog dialog = new DatePickerDialog(this, TRIM_MEMORY_RUNNING_LOW, new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
// TODO Auto-generated method stub
}
}, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH),calendar.get(Calendar.DAY_OF_MONTH));
dialog.show();
