There is an example like that in the ApiDemos (came with SDK 1.1, not
1.5 - don't know why?). Anyway, you should download SDK 1.1 and start
ApiDemos in 1.1 emulator, and play around a little. There is a Dialog
example in com.example.android.apis.app.AlertDialogSample.java, and
here is the part of code that concerns you:
public class AlertDialogSamples extends Activity {
private static final int DIALOG_TEXT_ENTRY = 7;
@Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DIALOG_TEXT_ENTRY:
// This example shows how to add a custom layout to an
AlertDialog
LayoutInflater factory = LayoutInflater.from(this);
final View textEntryView = factory.inflate
(R.layout.alert_dialog_text_entry, null);
return new AlertDialog.Builder(AlertDialogSamples.this)
.setIcon(R.drawable.alert_dialog_icon)
.setTitle(R.string.alert_dialog_text_entry)
.setView(textEntryView)
.setPositiveButton(R.string.alert_dialog_ok, new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int
whichButton) {
/* User clicked OK so do some stuff */
}
})
.setNegativeButton(R.string.alert_dialog_cancel, new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int
whichButton) {
/* User clicked cancel so do some stuff */
}
})
.create();
}
return null;
}
//and here is how you show your dialog
public boolean onMenuItemSelected(int featureId, MenuItem item) {
switch(item.getItemId()) {
case INSERT_ID:
showDialog(DIALOG_TEXT_ENTRY);
return true;
}
return super.onMenuItemSelected(featureId, item);
}
} // end AlertDialogSamples
//////////////////////////////////// Here is the layout inflated into
dialog
<?xml version="1.0" encoding="utf-8" ?>
- <LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:orientation="vertical">
<TextView android:id="@+id/username_view"
android:layout_height="wrap_content"
android:layout_width="wrap_content" android:layout_marginLeft="20dip"
android:layout_marginRight="20dip" android:text="@string/
alert_dialog_username" android:gravity="left" android:textAppearance="?
android:attr/textAppearanceMedium" />
<EditText android:id="@+id/username_edit"
android:layout_height="wrap_content"
android:layout_width="fill_parent" android:layout_marginLeft="20dip"
android:layout_marginRight="20dip" android:scrollHorizontally="true"
android:autoText="false" android:capitalize="none"
android:gravity="fill_horizontal" android:textAppearance="?
android:attr/textAppearanceMedium" />
<TextView android:id="@+id/password_view"
android:layout_height="wrap_content"
android:layout_width="wrap_content" android:layout_marginLeft="20dip"
android:layout_marginRight="20dip" android:text="@string/
alert_dialog_password" android:gravity="left" android:textAppearance="?
android:attr/textAppearanceMedium" />
<EditText android:id="@+id/password_edit"
android:layout_height="wrap_content"
android:layout_width="fill_parent" android:layout_marginLeft="20dip"
android:layout_marginRight="20dip" android:scrollHorizontally="true"
android:autoText="false" android:capitalize="none"
android:gravity="fill_horizontal" android:password="true"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
Hope this helps!
