Custom dialog usages in Android programming _android

This example describes the custom dialog usage in Android programming. Share to everyone for your reference, specific as follows:

Dialog is a set of pop-up prompts in Android that works very well, but its style is a stereotype, and sometimes we need to define our own style.

1, the definition of a style file, this file inherits from Theme.dialog, in the Style.xml file to create a style of their own

<style name= "Addnotetype_error_dialog" parent= "@android: Theme.dialog" >
  <item name= "Android: Windowframe "> @null </item>
  <item name=" Android:windownotitle ">true</item>
  <item Name= "Android:windowbackground" > @color/color_shenhui</item>
  <item name= "Android: Windowisfloating ">true</item>
  <item name=" Android:windowcontentoverlay "> @null </item>
</style>

2, a new layout, as a pop-up box display

<?xml version= "1.0" encoding= "Utf-8"?> <linearlayout xmlns:android= "http://schemas.android.com/apk/res/"
 Android "Android:layout_width=" Wrap_content "android:layout_height=" wrap_content "android:orientation=" vertical " android:background= "#DFDFDF" > <textview android:layout_width= "fill_parent" android:layout_height= "50DP" Andr
  Oid:gravity= "center_vertical" android:layout_marginleft= "5DP" android:text= "@string/txt_addnotetype_error_title" Android:textcolor= "#00CCFF" android:textsize= "18sp"/> <view android:layout_width= "Fill_parent" android:l ayout_height= "1px" android:background= "#00CCFF"/> <textview android:layout_width= "Fill_parent" Android:lay out_height= "50DP" android:gravity= "Left|center" android:layout_margintop= "5DP" android:text= "@string/txt_
   Addnotetype_error_content_null "/> <view android:layout_width=" fill_parent "android:layout_height=" 1px " Android:background= "#BBB9BA" Android:layout_margintop= "5DP"/> <button android:id= "@+id/btn_add_note_addnotetype_error_ok" android:layout_width= "Fill_parent" android:layout_height= "50DP" android:text= "@string/txt_ok" android:background= "@null"/> </linearlayout

3. Call this dialog

Here is a direct new dialog object, which is passed into the theme
Dialog = New dialog (Sel_notetypeactivity.this, R.style.addnotetype_error_ Dialog);
Set its Contentview
Dialog.setcontentview (r.layout.dialog_addnotetype_error);
Button BTN_ADD_NOTE_ADDNOTETYPE_ERROR_OK = (button) Dialog.findviewbyid (R.ID.BTN_ADD_NOTE_ADDNOTETYPE_ERROR_OK);
Btn_add_note_addnotetype_error_ok.setonclicklistener (New Addnotetypeerroclicklistener ());
Dialog.show ();

button click event:

Class Addnotetypeerroclicklistener implements onclicklistener{
  @Override public
  void OnClick (View v) {
   TODO auto-generated Method Stub
   dialog.cancel ();
  }

Sometimes we want to set the width or height of the dialog, which is relatively simple, add the following code directly under Dialog.show ():

Windowmanager.layoutparams layoutparams = Dialog.getwindow (). GetAttributes ();
Layoutparams.width = (int) (Mscreenwidth *9/10); Set width
dialog.getwindow (). SetAttributes (Layoutparams);

I hope this article will help you with the Android program.
