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

 

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

 

 

 

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

 

 

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

 

 

AlertDialog.Builder builder = new AlertDialog.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 = new AlertDialog.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;

window.setAttributes(lp);

。。。

dialog.show();
