<Setxmlns:android= "Http://schemas.android.com/apk/res/android"Android:shareinterpolator= "false" >    < ScaleAndroid:fromxscale= "0.9"Android:toxscale= "1.0"Android:fromyscale= "0.9"Android:toyscale= "1.0"Android:pivotx= "50%"Android:pivoty= "50%"android:duration= "$" />    <AlphaAndroid:fromalpha= "0.0"Android:toalpha= "1.0"android:duration= "$" />   </Set>

Exit

<Setxmlns:android= "Http://schemas.android.com/apk/res/android"Android:shareinterpolator= "false">    < Scaleandroid:duration= "$"Android:fromxscale= "1.0"Android:fromyscale= "1.0"Android:pivotx= "50%"Android:pivoty= "50%"Android:toxscale= "0.9"Android:toyscale= "0.9"/>    <Alphaandroid:duration= "$"Android:fromalpha= "1.0"Android:toalpha= "0.0"/></Set>

Third, set the style in the construction method

Context mcontext;      Public Mydialog (Context context) {        Super(context, r.style.mydialog);         this. mcontext=context;            }

Iv. Setting the layout

@Override     protected void onCreate (Bundle savedinstancestate) {        super. OnCreate (savedinstancestate);        Setcontentview (R.layout.layout_dialog);    }

The layout file is 2 TextView

V. Rewrite the show method, set width, height, etc.

  @Override  public  void   Show () { super  .show ();  /**   * Set width full screen, to be set after show  */  Layoutparams layoutparams  = GetWindow (). Getatt        Ributes ();        layoutparams.gravity  =gravity.bottom;        Layoutparams.width  = layoutparams.match_parent;        Layoutparams.height  = layoutparams.wrap_content;        GetWindow (). Getdecorview (). Setpadding ( 0, 0, 0, 0);    GetWindow (). SetAttributes (Layoutparams); }

Six, complete dialog class

/*** Dialog July 30, 2016*/ Public classMydialogextendsDialog {Context mcontext;  PublicMydialog (Context context) {Super(context, r.style.mydialog);  This. mcontext=context; } @Overrideprotected voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate);    Setcontentview (R.layout.layout_dialog); } @Override Public voidShow () {Super. Show (); /*** Set width full screen, to be set at the back of show*/Layoutparams Layoutparams=GetWindow (). GetAttributes (); Layoutparams.gravity=Gravity.bottom; Layoutparams.width=layoutparams.match_parent; Layoutparams.height=layoutparams.wrap_content; GetWindow (). Getdecorview (). setpadding (0, 0, 0, 0);    GetWindow (). SetAttributes (Layoutparams); }    }
