如果预构建的小部件或布局都不符合您的需求,您可以创建自己的View子类。如果您只需要对现有的小部件或布局进行小的调整,您可以简单地对小部件或布局进行子类化并覆盖其方法。
创建自己的View子类可以精确控制 屏幕元素的外观和功能。
但是,您可以轻松extend the existing one and create your own。
此外,如果您只是想让您的用户界面变得模糊,那么您可以查看DateSlider。

从对话框中选择日期并在TextView中显示。
public class DatePickerDemoActivity extends Activity {
/** Called when the activity is first created. */
private TextView mDateDisplay;
private Button mPickDate;
private int mYear;
private int mMonth;
private int mDay;
static final int DATE_DIALOG_ID = 0;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// capture our View elements
mDateDisplay = (TextView) findViewById(R.id.dateDisplay);
mPickDate = (Button) findViewById(R.id.pickDate);
// add a click listener to the button
mPickDate.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showDialog(DATE_DIALOG_ID);
}
});
// get the current date
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
// display the current date (this method is below)
updateDisplay();
}
// updates the date in the TextView
private void updateDisplay() {
mDateDisplay.setText(getString(R.string.strSelectedDate,
new StringBuilder()
// Month is 0 based so add 1
.append(mMonth + 1).append("-")
.append(mDay).append("-")
.append(mYear).append(" ")));
}
// the callback received when the user "sets" the date in the dialog
private DatePickerDialog.OnDateSetListener mDateSetListener =
new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
mYear = year;
mMonth = monthOfYear;
mDay = dayOfMonth;
updateDisplay();
}
};
@Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:
return new DatePickerDialog(this, mDateSetListener, mYear, mMonth,
mDay);
}
return null;
}
}
