自定义包含DatePicker的AlertDialog

1.创建AlertDialog中需要加载的布局borndate_dialog.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/borndate_dialog_background">
<TextView
android:id="@+id/textView_title_mydialog"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:text="请选择出生日期"
android:textColor="@color/white"
android:gravity="center"
android:textSize="22sp"
>
</TextView>
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:layout_marginTop="15dp"
android:background="@color/white"></View>
<DatePicker
android:id="@+id/DatePicker_student_born_date"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:layout_gravity="center"
></DatePicker>
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:layout_marginTop="15dp"
android:background="@color/white"></View>
<Button
android:id="@+id/button_student_mydialog"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignBottom="@+id/imageView_background_mydialog"
android:layout_marginTop="1dp"
android:layout_centerHorizontal="true"
android:background="@drawable/selector_button_bg_setting"
android:textSize="22sp"
android:textColor="@color/white"
android:gravity="center"
android:text="确定" />
</LinearLayout>

2.brondate_dialog_background:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<corners android:radius="5dp"></corners>
<solid android:color="@color/select_day"></solid>
</shape>

3.selector_button_bg_setting:

<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="@drawable/button_bg_default_pressed" />
<item android:state_focused="true" android:drawable="@drawable/button_bg_default_pressed" />
<item android:state_enabled="false" android:drawable="@drawable/button_bg_disabled" />
<item android:drawable="@drawable/button_bg_default_normal" />
</selector>

4.Acitivity中的代码：

tv_student_born_date.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog=new AlertDialog.Builder(StudentAttributeSettingActivity.this).create();
dialog.show();
dialog.getWindow().setContentView(R.layout.borndate_dialog);
//dialog.getWindow().setGravity(Gravity.CENTER_HORIZONTAL|Gravity.BOTTOM);//设置Dialog现实的位置
datePicker= (DatePicker) dialog.getWindow().findViewById(R.id.DatePicker_student_born_date);
Calendar calendar=Calendar.getInstance();
datePicker.init(calendar.get(Calendar.YEAR),
calendar.get(Calendar.MONTH),
calendar.get(Calendar.DAY_OF_MONTH), null);
dialog.getWindow().findViewById(R.id.button_student_mydialog).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
StringBuilder sb=new StringBuilder();
sb.append(
String.format("%d-%02d-%02d",
datePicker.getYear(),
datePicker.getMonth()+1,
datePicker.getDayOfMonth()));
LogUtil.i("borndate_sb",sb.toString()+"");
tv_student_born_date.setText(sb.toString());
dialog.dismiss();
}
});
}
});
