我想显示具有透明背景的警报对话框。我的警报对话框代码是:

AlertDialog.Builder imageDialog = new AlertDialog.Builder(SubProducts.this);
LayoutInflater inflater = (LayoutInflater)SubProducts.this.getSystemService(LAYOUT_INFLATER_SERVICE);

View layout = inflater.inflate(R.layout.cust_toast_layout,(ViewGroup)findViewById(R.id.linearLayout2));

ImageView image = (ImageView)layout.findViewById(R.id.imageView1);
image.setPadding(0, 20, 0, 0);
imgLoader.DisplayImage(image_url, loader, image);


TextView tprice=(TextView)layout.findViewById(R.id.pricetext);
tprice.setText("$ "+pricedouble);

TextView tvdprh=(TextView)layout.findViewById(R.id.textView1);

tvdprh.setText(prohd);




WebView wv=(WebView)layout.findViewById(R.id.webview);



Spanned sub=Html.fromHtml(descp);
String s = "<html><head><style type='text/css' >@font-face {font-family:'myfont';src: url('file:///android_asset/fonts/ABeeZee-Regular.ttf');}body {margin:0px;color:000000;font-family: myfont;"
+ "text-align: justify;}</style></head><body>"
+ sub
+ "</body></html>";

wv.loadDataWithBaseURL("", s, "text/html", "utf-8", null);
wv.setVerticalScrollBarEnabled(true);
wv.setBackgroundColor(Color.TRANSPARENT);
wv.setPadding(5, 25, 5, 0);


ImageView imgcartl=(ImageView)layout.findViewById(R.id.imageView2);
imgcartl.setBackgroundResource(R.drawable.cartlines);

ImageView brobutton=(ImageView)layout.findViewById(R.id.imageView3);
brobutton.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {



Intent intentlabl = new Intent(getBaseContext(), Label.class);
Bundle b=new Bundle();
b.putString("url", image_urlpdf);
b.putBoolean("isDialog", true);
intentlabl.putExtras(b);
startActivity(intentlabl);

}
});

ImageView shobutton=(ImageView)layout.findViewById(R.id.imageView4);

shobutton.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
//intent code
}
});

ImageView addbutton=(ImageView)layout.findViewById(R.id.imageView5);
addbutton.setBackgroundResource(R.drawable.addicon);
addbutton.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
// TODO Auto-generated method stub

passingid.add(prodid);

Product prodobj=new Product();
prodobj.setId(passingid);


new LongRunningGetIO4().execute(pricedouble, prodid);
}
});


imageDialog.setView(layout);


imageDialog.create();
imageDialog.show();

我的背景图片包含圆角。但不幸的是,pop 出现在矩形白色背景上。任何 body 请向我提出想法。在此先感谢。

最佳答案

styles.xml 文件中定义以下内容

<style name="CustomDialog" parent="android:Theme.Dialog">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">@android:color/transparent</item>
</style>

并将其作为参数传递给 AlertDialog 构造函数

AlertDialog.Builder imageDialog = new AlertDialog.Builder(SubProducts.this, R.style.CustomDialog);

或者以编程方式,通过Dialog实例可以调用

myDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT))
