Question

android 自定义dialog如何去掉半透明

Answer 1

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();
