How to implement customized Dialog with transparent background?¶

If you want to display a dialog with buttons such as OK,Cancel, you can use an AlertDialog which extends the Dialog class. But the AlertDialog leaves less customization space for you to set the theme, such as a transparent background, customized background picture...(whatever, I could not find the solutions, if you know it, pls tell me, thanks.)

You can not construct an AlertDialog by using the constructor, you should use AlertDialog.Builder class to build your AlertDialog, it is very easy by

AlertDialog.Builder builder = new AlertDialog.Builder();//static inner class 
builder.setTitle().setIcon().setMessage(); 
builder.setPositiveButton().setNegativeButton().setNeutralButton(); 
builder.setItems().setAdapter().setCursor().setMultiChoiceItems().setSingleChoiceItems(); 
builder.create();

But I could not find a way to set the theme of an AlertDialog. The theme of an AlertDialog was internally used.

<style name="Theme.Dialog.Alert"> 
    <item name="windowBackground">@android:color/transparent</item> 
    <item name="windowTitleStyle">@android:style/DialogWindowTitle</item> 
    <item name="windowIsFloating">true</item> 
    <item name="windowContentOverlay">@null</item> 
</style>

While, for the public class Dialog, you can use new Dialog(Context ctx, int theme) to specify the theme you want use. The default theme for a Dialog is defined as below:

<style name="Theme.Dialog"> 
    <item name="android:windowFrame">@null</item> 
    <item name="android:windowTitleStyle">@android:style/DialogWindowTitle</item> 
    <item name="android:windowBackground">@android:drawable/panel_background</item> 
    <item name="android:windowIsFloating">true</item> 
    <item name="android:windowContentOverlay">@null</item> 
    <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item> 
    <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item> 
</style>

But you can define a theme or style in your $proj/res/values/styles.xml file and apply it to your dialog.

You can also apply the Theme.Dialog to an Activity, then the activity will appear looks like a dialog.

More details about Dialog & AlertDialog, refer the ApiDemos application.

기본적으로 android 에서 dialog 를 만들어 띄우면 다음과 같은 모습니다

너무 케간단해서 글로 올리기가 민망하구먼;;


LayoutInflater mInflater = getLayoutInflater();
View dialogLayout = mInflater.inflate(R.layout.dialog_notic01,(ViewGroup)findViewById(R.drawable.popup_bg));

Dialog mDialog = new Dialog(this);
mDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
mDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
mDialog.setContentView(dialogLayout);
mDialog.show();
자 이런시긍로 하는 거임.ㅋ

heme 를 Dialog 로 지정하면 해당 팝업 뒤에 Activity 의 Label 이 출력되는 부분이 나오는것 같더라구요

혹시 onCreate 안에 this.setVisible(false); 를 주어도 같은 현상이 나는지 궁금해 집니다

다음 추가해보세요. 어디서 본건지 기억이 안나는...

1.protected void onApplyThemeResource(Resources.Theme theme, int resid, boolean first) {

2.super.onApplyThemeResource(theme, resid, first);

3.// no background panel is shown

4.theme.applyStyle(style.Theme_Panel, true);

5.

자신이 만든 xml view 만 보이게 하기

 View popupView = View.inflate(act, R.layout.cchatpopup, null);
        

 AlertDialog _ab = new AlertDialog.Builder(act)
        .show();
       
        _ab.getWindow().setBackgroundDrawable(new ColorDrawable(0x0000ff00)); 
        _ab.setContentView(popupView);
