[android-developers] Re: How is android's AlertDialog layout define?
usually your layout is defined in an xml file (in res/layout) and in
your Java-like Android code you can reference it so:
d.setContentView(R.layout.dialog_view);
where d is an instance of AlertDialog.
and dialog_view.xml could contain:
?xml version=1.0 encoding=utf-8?
RelativeLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:layout_width=fill_parent
android:layout_height=fill_parent
!-- android:title=any title does not work
--
TextView
android:id=@+id/label
android:layout_width=fill_parent
android:layout_height=wrap_content
android:text=The search is case sensitive:/
EditText
android:id=@+id/entry
android:layout_width=fill_parent
android:layout_height=wrap_content
android:background=@android:drawable/editbox_background
android:layout_below=@id/label/
Button
android:id=@+id/find
android:layout_width=wrap_content
android:layout_height=wrap_content
android:layout_below=@id/entry
android:layout_alignParentLeft=true
android:layout_marginRight=10dip
android:text=Find Next /
Button
android:id=@+id/cancel_search
android:layout_width=wrap_content
android:layout_height=wrap_content
android:layout_toRightOf=@id/find
android:layout_alignTop=@id/find
android:text=Cancel /
/RelativeLayout
The above answers your direct question but there are a few different
ways to use such a layout.
I know 5 techniques for setting up an AlertDialog (details are below):
1. Dialog parent class: if you need to roll a simple version.
2. AlertDialog plain (without the builder): not recommended but works.
3. AlertDialog.Builder: classic; probably better than the above 2.
4. Using the two Activity methods that are called by Android: great
for persisting AlertDialog instances = better performance.
5. Using an Activity that looks like a Dialog: for fancy stuff.
Details:
1. Dialog parent class: a mix of code and xml layout
Dialog d = new Dialog(this); //*this* is the Activity
Window w = d.getWindow((;
w.setFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND,
WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
d.setTitle(Dialog (not alert));
//your layout defined in an xml file (in res/layout)
d.setContentView(R.layout.dialog_view);
d.show();
2. AlertDialog plain (not recommended but works)
I sometimes use this technique in an uncaughtException method.
AlertDialog error = new AlertDialog(this){
//*this* is the Activity because it needs the Context.
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
}
};
error.setTitle(Anomaly Detected);
error.setMessage(A possible defect has been detected in
+getString(R.string.app_name)
+ v. +getString(R.string.versionString)
+\nFor support, please write m...@myplace.com);
error.show();
There are more complex versions of this technique but the other
techniques below are better.
3. The AlertDialog.Builder technique: recommended, as are # 4 and 5
below.
AlertDialog.Builder bookmarkDialog = new AlertDialog.Builder(this);
//*this* is the Activity because it needs the Context.
bookmarkDialog.setIcon(android.R.drawable.ic_menu_myplaces);
bookmarkDialog.setTitle(Bookmark +getString(R.string.app_name));
AlertDialog ad = bookmarkDialog.create();
ad.requestWindowFeature(Window.FEATURE_LEFT_ICON);
//more setup here...
//setup completed:
bookmarkDialog.show();
4. Using Activity methods called by Android: good for persisting
AlertDialog instances
4.1. you override these 2 methods:
onCreateDialog(int yourId)
//called by Android the first time that you call showDialog.
//You may use the AlertDialog.Builder technique in this method.
onPrepareDialog(int yourId, Dialog dialog)
//called by Android each time the dialog is shown.
//You don't create any dialog instance here; use the one given.
//You can do things like
dialog.setMessage(new message with new info);
4.2. and you do this somewhere in your code:
showDialog(yourUniqueDialogId);
4.3. yourUniqueDialogId must be defined by you, usually as a static
field; must be an int.
5. Using an Activity that looks like a Dialog:
activity android:name=.ActivityDialog1
android:theme=@android:style/Theme.Dialog
/activity
And you manage the Activity like any another Activity.

[android-developers] Re: How is android's AlertDialog layout define?
Thank you for both of your answers.
In the android source, it has:
* If you
* want to display a more complex view, look up the FrameLayout called body
* and add your view to it:
*
* pre
* FrameLayout fl = (FrameLayout) findViewById(R.id.body);
* fl.add(myView, new LayoutParams(FILL_PARENT, WRAP_CONTENT));
* /pre
How can I hook up to that?
Do I need to create a layout xml file with 'body' as it name?
And how can I make an AlertDialog loads that layout xml?
Thank you.
