本文介绍如何在Android应用中使用AlertDialog.Builder创建不同样式的对话框，包括传统主题、深色与浅色Holo主题、设备默认主题及自定义布局，并展示了如何调整对话框的透明度。

AlertDialog.Builder(DialogActivity.this,AlertDialog.THEME_TRADITIONAL);//传统主题

AlertDialog.Builder builder =newAlertDialog.Builder(DialogActivity.this,AlertDialog.THEME_HOLO_DARK);//使用深色背景主题

AlertDialog.Builder builder =newAlertDialog.Builder(DialogActivity.this,AlertDialog.THEME_HOLO_LIGHT);//使用浅色背景主题

AlertDialog.Builder builder =newAlertDialog.Builder(DialogActivity.this,AlertDialog.THEME_DEVICE_DEFAULT_DARK);//使用默认设备深色主题

AlertDialog.Builder builder =newAlertDialog.Builder(DialogActivity.this,AlertDialog.THEME_DEVICE_DEFAULT_LIGHT);//使用默认设备浅色主题

//自定义布局

View layout =getActivity().getLayoutInflater().inflate(R.layout.mydialog,null);

AlertDialog.Builder dialog =newAlertDialog.Builder(DialogActivity.this,AlertDialog. THEME_DEVICE_DEFAULT_DARK);

final AlertDialog dialog = builder.create();

dialog.setView(layout);

//透明

Window window =dialog.getWindow();

WindowManager.LayoutParams lp =window.getAttributes();
lp.alpha = 0.9f; //透明度
lp.dimAmout = 1f; //黑暗度

window.setAttributes(lp);

dialog.show();
