Android Custom Popupwindow Instance code _android

Let's take a look at the effect chart:

First, the layout

<?xml version= "1.0" encoding= "Utf-8"?> <linearlayout xmlns:android=
"http://schemas.android.com/apk/" Res/android "
  android:layout_width=" match_parent "
  android:layout_height=" wrap_content "
  android:o" rientation= "vertical"
  android:background= "#ffffff"
  android:padding= "20DP" >

  <textview
    Android:layout_width= "Match_parent"
    android:layout_height= "wrap_content"
    android:clickable= "true"
    android:gravity= "center"
    android:textcolor= "@android: Color/holo_orange_dark"
    android:text= "OK" />

  <textview
    android:layout_margintop= "20DP"
    android:layout_width= "Match_parent"
    android:layout_height= "Wrap_content"
    android:layout_marginbottom= "10DP"
    android:clickable= "true"
    android:gravity= "center"
    android:text= "Cancel"/>

</LinearLayout>

2, custom Mypopupwindow inheritance Popupwindow

public class Mypopupwindow extends Popupwindow {

3, rewrite the construction method and animation style
in Styles.xml custom style, animation

<style name= "Mypopupwindow" >

    <item name= "android:windowenteranimation" > @anim/pop_in</item>
    <item name= "android:windowexitanimation" > @anim/pop_out</item>
  </style>

Pop_in

<?xml version= "1.0" encoding= "Utf-8"?> <set xmlns:android=
"http://schemas.android.com/apk/res/" Android >

  <!--translation
  <translate
     android:duration= "5000"
     android:fromxdelta= "100%"

     Android:toxdelta= "0"/>
     -->

  <scale
    android:fromxscale= "0"
    android:fromyscale= "0"
    android:pivotx= "50%"
    android:pivoty= "50%" android:toxscale= "0.8"
    android:toyscale= "0.5"
    android:duration=/>

  <!--

 -->

  <!--transparency-->
  <alpha
    android:duration= "200"
    android:fromalpha= "0.0"

    android:toalpha= "1.0"/>


</set>

Pop_out

<?xml version= "1.0" encoding= "Utf-8"?> <set xmlns:android=
"http://schemas.android.com/apk/res/" Android ">

  <!--<translate
    android:duration=" 5000 "
    android:fromxdelta=" 0 "

    android: Toxdelta= "100%"/>--> <scale android:fromxscale= "0.8" android:fromyscale=
    "0.5"
    Android :p ivotx= "50%"
    android:pivoty= "50%"
    android:toxscale= "0"
    android:toyscale= "0"
    android: duration= "/>



  <alpha
    android:duration=" android:fromalpha= "1.0"

    android: Toalpha= "0.0"/>

</set>

4, rewrite the construction method and set the click outside can disappear listening

 Super (context);
    This.mcontext=context;


    Pump minflater = (layoutinflater) context.getsystemservice (Context.layout_inflater_service);

    Pep Mcontentview = minflater.inflate (r.layout.layout_dialog,null);


    Set View Setcontentview (Mcontentview);

    Set wide and high setwidth (WindowManager.LayoutParams.MATCH_PARENT);


    SetHeight (WindowManager.LayoutParams.WRAP_CONTENT);


    /** * Set in and out of animation/Setanimationstyle (R.style.mypopupwindow);


    /** * Setting background only this can be clicked outside and back disappears * * setbackgrounddrawable (new colordrawable ());

    /** * settings can get the set point * * Setfocusable (TRUE);

    /** * Set Click on the outside can disappear * * setoutsidetouchable (TRUE);


    /** * settings can touch/settouchable (TRUE); /** * Settings Click External can disappear * * Settouchinterceptor (new View.ontouchlistener () {@Override public boolean O Ntouch (View V, motionevent event) {/** * judgment is not clicked on the external */if (event.getaction () ==motIonevent.action_outside) {return true;
      ///Not click External return false;

 }
    });

5, display and set the window darken and lighten

public void Displaydialog (view view) {

    Mypopupwindow Mypopupwindow = new Mypopupwindow (this);

    Mypopupwindow.showasdropdown (mbtndispaly,0,0);
    Lightoff ();


    /**
     * When the screen becomes bright
    /Mypopupwindow.setondismisslistener (new Popupwindow.ondismisslistener () {
      @ Override public
      void Ondismiss () {
        Windowmanager.layoutparams layoutparams = GetWindow (). GetAttributes ();

        layoutparams.alpha=1.0f;

        GetWindow (). SetAttributes (Layoutparams);}}
    );

  /**
   * Display when the screen dims
   /
  private void Lightoff () {

    Windowmanager.layoutparams layoutparams = GetWindow (). GetAttributes ();

    layoutparams.alpha=0.3f;

    GetWindow (). SetAttributes (layoutparams);
