The Android implementation can use custom transparent dialog-style activity complete instances _android

The example in this article describes an activity that the Android implementation can use to customize the transparent dialog style. Share to everyone for your reference, specific as follows:

Sometimes you need a dialog box, but the content in the dialog box has more control and control over its lifecycle, and you can use a dialog-style activity to apply your project, so that the activity has a dialog box that can be added to the androidmanifest Theme features of Android:style/theme.dialog

For example this:

<activity android:name= "mydialogactivity"
    android:theme= "@android: Style/theme.dialog" >
</ Activity>

If you feel that the above is not enough to meet your needs to achieve translucent, rounded corners, you may wish to try the custom dialog box style

First of all

The first step : Prepare to do a good job. 9 pictures

Step two : Custom style Creates a Styles.xml file in your project values folder

Then add a style named Mydialogstyle to the styles file

<style name= "Mydialogstyle" >
    <item name= "Android:windowbackground" > @android: Color/transparent </item>
    <item name= "Android:windowframe" > @null </item>
    <item name= "Android: Windownotitle ">true</item>
    <item name=" android:windowisfloating ">true</item>
    < Item Name= "Android:windowistranslucent" >true</item>
    <item name= "Android:windowcontentoverlay" > @null </item>
    <item name= "Android:windowanimationstyle" > @android: style/animation.dialog</ item>
    <item name= "android:backgrounddimenabled" >true</item>
</style>

Step three : Dialog layout adds a layout file to the Layout folder Activity_main.xml

<relativelayout xmlns:android= "http://schemas.android.com/apk/res/android" xmlns:tools= "http:// Schemas.android.com/tools "android:layout_width=" match_parent "android:layout_height=" Match_parent "> < 
    Relativelayout android:layout_width= "180DP" android:layout_height= "180DP" android:layout_centerinparent= "true" android:background= "@drawable/loading_bg" > <linearlayout android:layout_width= "fill_parent" an
      droid:layout_height= "Fill_parent" android:layout_alignparentleft= "true" android:layout_alignparenttop= "true" android:gravity= "center" android:orientation= "vertical" > <progressbar android:id= "@+id/pro" GressBar1 "style="? Android:attr/progressbarstylelarge "Android:layout_width=" Wrap_content "Android : layout_height= "wrap_content" android:layout_gravity= "Center_horizontal"/> <textview android: Layout_width= "Wrap_content" android:layout_height= "Wrap_content" android:layout_margintop= "10DP" android:text= "Logging on" android:textcolor= "#fff"

 Android:textsize= "20sp"/> </LinearLayout> </RelativeLayout> </RelativeLayout>

Create Dialogactivity Class

public class Dialogactivity extends activity
{
  @Override
  protected void OnCreate (Bundle Savedinstancestate)
  {
    super.oncreate (savedinstancestate);
    Setcontentview (r.layout.activity_main);
    Here you can do some waiting operation, I here in 8 seconds after the toast agent waiting for the operation of the
    New Handler (). postdelayed (New Runnable () {
      @Override public
      void Run () {
        DialogActivity.this.finish ();
        Toast.maketext (Getapplicationcontext (), "Login Successful", Toast.length_short). Show ();
      }
    , 8000);
  }

Step Fourth : Register the dialogactivity in the manifest file and use the custom Mydialogstyle style above

<activity
   android:name= "loadingactivity"
   android:theme= "@style/mydialogstyle"/>

Step Fifth : Run the project and view the effect chart

Finish the call.
