Android Custom Popup effect

Android 's pop-up effect there are many kinds of, in the simplest case, you can call a alertdialog pop-up window display, but to customize the pop-up window effect has the following method, I personally feel very convenient, applicability is quite wide.

First of all, write a simple use of alertdialog

public void ShowDialog () {alertdialog dialog = new Alertdialog.builder (this). Settitle ("hint"). Setmessage (Getresources () . getString ("Are you sure you want to quit?"). Setpositivebutton ("Cancel", new Onclicklistener () {@Overridepublic void OnClick (dialoginterface dialog, int which) { Dialog.dismiss ();}}). Setnegativebutton ("OK", new Onclicklistener () {@Overridepublic void OnClick (dialoginterface dialog, int which) {//TODO A uto-generated method Stub}}). Create ();d ialog.show ();}}

The next step is to customize the pop-up window:

Here is the sample code:

<?xml version= "1.0" encoding= "Utf-8"? ><relativelayout xmlns:android= "http://schemas.android.com/apk/res/     Android "Android:layout_width=" Match_parent "android:layout_height=" wrap_content "android:orientation=" vertical " > <linearlayout android:layout_width= "match_parent" android:layout_height= "Wrap_content" Androi        D:gravity= "Center_horizontal" android:orientation= "vertical" android:layout_alignparentbottom= "true" Android:id= "@+id/top" > <textview android:layout_width= "match_parent" android:layout_height = "40.5dip" android:text= "@string/select_head" android:layout_marginleft= "7.2dip" Android:        layout_marginright= "7.2dip" android:gravity= "center" android:textcolor= "#aaaaaa"/> <button android:id= "@+id/takephoto" android:layout_width= "Match_parent" android:l           ayout_height= "40.5dip" android:layout_marginleft= "7.2dip" android:layout_marginright= "7.2dip" android:text= "@string/takeph            Oto "android:background=" @null "android:textcolor=" #fc4643 "/> <button Android:id= "@+id/selectfromalbum" android:layout_width= "Match_parent" android:layout_height= " 40.5dip "android:layout_marginleft=" 7.2dip "android:layout_marginright=" 7.2dip "android:t         ext= "@string/takefromalbum" android:background= "@null" android:textcolor= "#fc4643"/> <button android:id= "@+id/cancel" android:layout_width= "Match_parent" android:l            ayout_height= "40.5dip" android:layout_marginleft= "7.2dip" android:layout_marginright= "7.2dip"            android:layout_margintop= "7.2dip" android:text= "@string/cancel" android:background= "@null" Android:textcolor= "#fc4643"/> </LinearLayout></RelativeLayout>
