android - 具有透明背景的对话框（带有任何颜色）

Question

I want blue translucent behind custome dialog box. but I am not getting blue color

Here is code of dialog declaration:

final Dialog dialog = new Dialog(BookAppointmentActivity.this,R.style.TranslucentBlue );
                //Dialog dialog = new Dialog(BookAppointmentActivity.this,  android.R.style.Theme_Translucent_NoTitleBar_Fullscreen );

                dialog.setContentView(R.layout.customedialog);
                Window window = dialog.getWindow();
                window.setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));


                dialog.show(); 

Here is my style.xml

<color name="transparent_green_color">@color/dialog_back</color>
    <style name="TranslucentBlue" parent="android:Theme.Translucent">
        <item name="android:windowBackground">@color/transparent_green_color</item>
    </style>

Answer 1

Ok I got the solution

First make change in theme. Don't make custome theme. Use android.R.style.Theme_Translucent_NoTitleBar_Fullscreen

final Dialog dialog = new Dialog(BookAppointmentActivity.this, android.R.style.Theme_Translucent_NoTitleBar_Fullscreen);

instead of custom theme, and add following:

window.setBackgroundDrawableResource(R.color.dialog_back);

Full code:

final Dialog dialog = new Dialog(context, android.R.style.Theme_Translucent_NoTitleBar_Fullscreen);

dialog.setContentView(R.layout.customedialog);
Window window = dialog.getWindow();

window.setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

window.setBackgroundDrawableResource(R.color.dialog_back);
dialog.show();

Use color from your resource file color.xml and at last but not least don't forget to decrease the opacity of the color.
