如何更改自定义警告对话框的背景 [英] How to change the background of the custom alert dialog

问题描述

我有一个自定义警告对话框，在其中我设置列表视图和它的背景是白色的。

但我得到这样的看法。

这是这是适合截图整个屏幕。

 对话D =新的对话框（背景下，android.R.style.Theme_Translucent_NoTitleBar）;
        CustomDialogListAdapter customDialogAdapter;
        ListView控件customList =新的ListView（背景）;
        customList.setLayoutParams（新的LayoutParams（LayoutParams.FILL_PARENT，LayoutParams.WRAP_CONTENT））;
        customList.setChoiceMode（ListView.CHOICE_MODE_SINGLE）;
        customDialogAdapter =新CustomDialogListAdapter（背景下，PaymentInfo.creditCardTypes，类型）;
        customList.setAdapter（customDialogAdapter）;
        customList.setBackgroundColor（Color.WHITE）;
        d.setContentView（customList）;
        d.show（）;
 

在此先感谢..！

解决方案

 上下文mContext = getApplicationContext（）;
对话的对话=新的对话框（mContext，android.R.style.Theme_Translucent_NoTitleBar）;
dialog.setContentView（R.layout.custom_dialog）;
dialog.show（）;
 

以上code将产生一个透明的对话框。所以，你的列表视图背景将是该对话框的唯一背景。

I have a custom alert dialog, in which i set a list view and its background is white.

But i am getting a view like this.

This is the screenshot which is fits entire screen.

 Dialog d = new Dialog(context,android.R.style.Theme_Translucent_NoTitleBar);       
        CustomDialogListAdapter customDialogAdapter;
        ListView customList = new ListView(context);
        customList.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
        customList.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
        customDialogAdapter = new CustomDialogListAdapter(context,PaymentInfo.creditCardTypes, type);
        customList.setAdapter(customDialogAdapter);
        customList.setBackgroundColor(Color.WHITE);
        d.setContentView(customList);
        d.show();

Thanks in advance..!

解决方案

Context mContext = getApplicationContext(); 
Dialog dialog = new Dialog(mContext,android.R.style.Theme_Translucent_NoTitleBar);
dialog.setContentView(R.layout.custom_dialog); 
dialog.show();

the above code will generate a transparent dialog box. So your listviews background will be the only background for the dialog box.
