All kinds of dialog

　Figure 1 Effect: This effect is a prompt that pops up when you press the Back button to ensure error-correct operation, using a common dialog box style.

Code:

Create a dialog box Method dialog ()

protected void dialog () {
Alertdialog.builder builder = new Builder (main.this);
Builder.setmessage ("Confirm exit?") ");

Builder.settitle ("hint");

Builder.setpositivebutton ("Confirm", new Onclicklistener () {

@Override
public void OnClick (Dialoginterface dialog, int which) {
Dialog.dismiss ();

Main.this.finish ();
}
});

Builder.setnegativebutton ("Cancel", new Onclicklistener () {

@Override
public void OnClick (Dialoginterface dialog, int which) {
Dialog.dismiss ();
}
});

Builder.create (). Show ();
}

This method is called in the onkeydown (int keycode, KeyEvent event) method

public boolean onKeyDown (int keycode, keyevent event) {
if (keycode = = Keyevent.keycode_back && event.getrepeatcount () = = 0) {
Dialog ();
}
return false;
}

　　Figure 2 Effect: Change the Chart of the dialog box, add three buttons

Dialog Dialog = new Alertdialog.builder (this). SetIcon (
Android. R.drawable.btn_star). Settitle ("Survey of Preferences"). Setmessage (
"Do you like Jet Li's movies?" "). Setpositivebutton (" Very like ",
New Onclicklistener () {

@Override
public void OnClick (Dialoginterface dialog, int which) {
TODO auto-generated Method Stub
Toast.maketext (Main.this, "I like his movie very much. ",
Toast.length_long). Show ();
}
}). Setnegativebutton ("Don't like", New Onclicklistener () {

@Override
public void OnClick (Dialoginterface dialog, int which) {
TODO auto-generated Method Stub
Toast.maketext (Main.this, "I don't like his movies. ", Toast.length_long)
. Show ();
}
}). Setneutralbutton ("General", new Onclicklistener () {

@Override
public void OnClick (Dialoginterface dialog, int which) {
TODO auto-generated Method Stub
Toast.maketext (Main.this, "I don't like it. ", Toast.length_long)
. Show ();
}
}). Create ();

Dialog.show ();

android:layout_height= "Wrap_content" android:layout_width= "Wrap_content"
Android:background= "#ffffffff" android:orientation= "Horizontal"
Android:id= "@+id/dialog" >
<textview android:layout_height= "Wrap_content"
Android:layout_width= "Wrap_content"
Android:id= "@+id/tvname" android:text= "Name:"/>
<edittext android:layout_height= "Wrap_content"
Android:layout_width= "Wrap_content" android:id= "@+id/etname" android:minwidth= "100dip"/>

</LinearLayout>

Layoutinflater inflater = Getlayoutinflater ();
View layout = Inflater.inflate (R.layout.dialog,
(ViewGroup) Findviewbyid (R.id.dialog));
