progress bar for [Android] components 2

This is a good example of the use of Alertdialog and layoutinflater in detail:

Main.xml

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <Button android:id="@+id/Button01" android:layout_height="wrap_content" android:text="非Layout型对话框" android:layout_width="fill_parent"> </Button> <Button android:id="@+id/Button02" android:layout_height="wrap_content" android:text="Layout型对话框" android:layout_width="fill_parent"> </Button> <View android:id="@+id/View01" android:layout_width="wrap_content" android:layout_height="wrap_content"> </View> </LinearLayout>

Dialoglayout.xml

<?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"> <EditText android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_marginLeft="20dip" android:layout_marginRight="20dip" android:textAppearance="?android:attr/textAppearanceMedium" android:id="@+id/edtInput"/> </LinearLayout>

Summary under:
1. For button, you can learn the above, a unified event to deal with.

2. In the actual development of the species layoutinflater this class is still very useful, its role is similar to Findviewbyid (),
The difference is that Layoutinflater is used to find layouts under the XML layout file and instantiate it! Instead, Findviewbyid () is looking for specific widget controls (such as: Button,textview, etc.) under specific XML.

3. Note the alertdialog here. Usage of Builder
