android中的ProgressDialog(进度)，DatePickerDialog（日期选择）与TimePickerDialog（时间选择）

ProgressDialog

AlertDialog的子类，并且有ProgressBar的控件
所以包含他们两个的方法
1. setMax,setProgress
2. get…
3. setTitle,setIcon,show,dismiss,
4. setProgressStyle 设置形状
5. setCancelable

DatePickerDialog与TimePickerDialog

DatePicker与TimePicker一样都含有Dialog的方法

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void progress1(View v) {
        final ProgressDialog dialog = new ProgressDialog(this);
        dialog.setTitle("提示");
        dialog.setMessage("正在加载");
        // 设置为水平样式
        dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        dialog.show();
        new Thread() {
            public void run() {
                int index = 0;
                while (index++ < dialog.getMax()) {
                    dialog.setProgress(index);
                    try {
                        Thread.sleep(100);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
            };
        }.start();
        // 关闭时一般判断
        //
        // if (dialog != null && dialog.isShowing())
        // dialog.dismiss();
    }

    public void datePicker(View v) {
        DatePickerDialog dialog = new DatePickerDialog(this,
                new OnDateSetListener() {

                    @Override
                    public void onDateSet(DatePicker view, int year,
                            int monthOfYear, int dayOfMonth) {
                        // 这里是用户选择完毕后的回调
                        Toast.makeText(
                                getBaseContext(),
                                year + "-" + (monthOfYear + 1) + "-"
                                        + dayOfMonth, Toast.LENGTH_SHORT)
                                .show();

                    }
                }, 2016, 11, 11);
        dialog.show();
    }

    public void timePicker(View v) {
        TimePickerDialog dialog = new TimePickerDialog(this,
                new OnTimeSetListener() {

                    @Override
                    public void onTimeSet(TimePicker view, int hourOfDay,
                            int minute) {
                        Toast.makeText(getBaseContext(),
                                hourOfDay + ":" + minute, Toast.LENGTH_SHORT)
                                .show();
                    }
                }, 11, 11, true);
        dialog.show();
    }
}

xml的设置

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:onClick="progress1"
        android:text="进度对话框" />

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:onClick="datePicker"
        android:text="日期选择器" />

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:onClick="timePicker"
        android:text="时间选择器" />
